Crossbreeding: It works for feral pigs

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Crossbreeding, bringing together parents that are distantly related but capable of producing viable offspring, has increased hybrid vigor within domestically raised livestock.Extensive research has shown positive improvement for several production traits, particularly survival traits that are lowly heritable. Interestingly, sometimes if one looks at what others are intentionally or not intentionally doing, one can learn a lot. The same is true about crossbreeding.The concept of domesticated livestock mating with their wild relatives is not new and generally not encouraged. The reason comes back to the increased hybrid vigor of the offspring and their tendency to out-compete the parents.In native environments, hybrid offspring can be very detrimental, particularly when reproductive capacity increases. For example, feral pigs are a very real, current and major problem. They are aggressive, productive and reproduce copiously.The domestic pig (Sus Scrofa) is capable of producing viable offspring when mated to several subspecies. The vigor of the offspring borders on aggressive and environmentally destructive, so laws have been enacted to control feral and/or hybrid pigs.In fact, several species of wildlife are protected from hybridization with closely related subspecies because the hybrids will, at times, outperform both parents and actually lower the population of the original parents. This hybrid vigor is real and not something to be taken lightly.In the canine world, dogs, coyotes and wolves can produce a hybrid that may have a selective advantage over the original parents. Florida is fearful of the potential hybridization of pythons. Although one may not think of snakes as domesticated, they are, some more so than others.Two snakes — the African rock python (Python sebae) and the Burmese python (Python molurus bivittatus) — keep making the news, primarily because of the fear they may crossbreed. When confined to their normal habitat, one in Sub-Saharan Africa and the other in southern and Southeast Asia, they do not cross. They fit their environment.Like beef producers who traveled the mountain passes and waterways, who also co-mingled different breeds and subspecies of cattle, those who appreciate raising snakes worry the same may occur. Imagine a snake the size of a Burmese python with the aggressive nature of the African rock python. Not a good thing.Fortunately, the actual crossing of these and most subspecies that result in viable, reproductively sound offspring is very rare. But the point is made: hybrid vigor is real. Much effort was made in crossing American bison with domestic cattle. Although not all the offspring are viable, enough viability existed to create the Beefalo breed, or cattle with bison and cattle DNA.I could continue, but the concept of hybrid vigor is accepted as real. And if not, then go try to herd some feral pigs. So, the discussion of hybrid vigor certainly has a place for beef producers. The beef industry can tone down the extremes of hybrid vigor and keep the good points: increased calf vigor that improves livability, increased reproductive potential and associated decreased costs.The premise of a good beef crossbreeding program was to keep the production unit, the cow, smaller and refine costs to make the cow practical but productive. The advantage came with a terminal sire, or one that would maintain all the pluses achieved with heterosis (the crossing of unrelated breeds), plus add unique traits associated with the selected breed of terminal sire. This was good. And the beef cattle breeding systems were expanded to handle more breeds.Programs maximized production through terminal sires or more sophisticated rotational breeding programs and allowed for the inclusion of new breeds on the maternal side. Crossbreeding works.Seedstock producers have improved their genetics through selection for increased production attained through selection for growth and other traits. The lowly heritable traits, however, still maintain the advantages attained though heterosis.So why the point? In the genetic world, remember that measureable and non-measurable advantages are evident as diverse genetics are crossed. That is simply fact, but the concept of developing crossbreeding systems has taken second seat to selection, potentially shrinking the tool chest.As new, cost-efficient beef systems are explored, a large tool chest is needed. Those early black baldy concepts were real as producers look to manage the right cows, cows that are reproductively superior, biologically efficient and wean calves that exceed the cows’ ability to grow.Now is a good time to think about terminal beef cattle systems.May you find all your ear tags.last_img read more

Conscious clothes

He,Amit Aggarwal, DelhiRecycling mantraWaste material to couture clothing.The couture garments in his studio in Lado Sarai are almost an indulgence into a compressed fantasia. Since 2009, Delhi-based designer Amit Aggarwal has been using unconventional material like plastic to make garments that have been hailed as the new sustainability alternative. He calls it “conscious fashion”. “Right from the choice of material, to the reason why a particular thing needs to be made and in what conditions and by whom, these are important questions one should ask oneself before creating conscious fashion,” he says.”I thought an interesting language of new-age textiles can be created through traditional craftsmanship using industrial byproducts,” he adds. The malleable, recycled polymer sheet is his signature material.”Recycling used plastic causes much less damage than many organic fibres, including cotton. Polyester, a derivative from plastic polymer, has seen radical improvements of late. As an alternative textile for clothing, it can easily be moulded into a variety of uses, from daily wear to performance clothing.”Aggarwal is challenging the notion that only cotton and silk are healthy while plastic is bad for the environment. “Indeed, their use together might ease the pressure brought by the huge consumption of cotton by the industry,” he says.A ‘GREEN’ IPL Photo by: Pawan BhawarDistrict Administration, IndoreRecycling mantra Recycle waste for environment-friendlier sports The objective was to recycle the waste generated during IPL matches and ultimately scale up to a ‘plastic-free’ IPL season in Indore by 2020. Awareness camps were held and volunteers deployed at the 30,000-capacity Indore cricket stadium. After the matches, some 300 ‘safai mitr’ segregated the waste generated-dry waste was sold to recyclers in the city; wet waste composted. In the four matches hosted by Indore (May 4-14), 7,500 kg of dry waste, including plastic, and 1,200 kg of wet waste was generated. A big chunk of it had been segregated by the spectators themselves. The initiative was funded by the Madhya Pradesh Cricket Association (MPCA) and IPL team Kings XI Punjab. “The idea was to ensure people learn to segregate waste and take the concept home,” says Rohit Pandit, chief administrative officer, MPCA.advertisementlast_img read more

Closure at busy USMexico border crossing promises headaches

first_imgSAN DIEGO – The busiest border crossing in the United States will close this weekend to the more than 40,000 cars that pass through it daily to Mexico.The closure between San Diego and Tijuana for work on a $741 million expansion project presents a monumental headache for border businesses, workers, tourists and Christopher Enjambre. His band, Minor Gems, plays gigs in Tijuana.“It’s already hectic now, so … damn,” he said, shaking his head in disbelief. “It’s going to be crazy.”Travellers have been enduring hours-long waits on the Mexican side of the border to enter the U.S. with the constant addition of security measures since the Sept. 11, 2001, attacks.Frequent crossers, like Enjambre, 28, of Chula Vista, south of downtown San Diego, worry they will now face long lines on both sides, making trips through the San Ysidro crossing intolerable.The expansion is believed to be the largest renovation of a crossing along the nearly 2,000-mile-long U.S.-Mexico border. It has been in the works for years to ease congestion and boost cross-border commerce.U.S. officials are warning people to avoid driving to Baja California from 3 a.m. Saturday until noon Monday, hoping to ease what is feared will be a massive traffic jam on the U.S. side as Mexico-bound cars are detoured to the much smaller Otay Mesa crossing to the east.“Don’t even think about going across in a vehicle,” said Jason M-B Wells, executive director of the San Ysidro Chamber of Commerce. “It’s going to be a standstill.”Wells and other business leaders want people to cross on foot and are planning a festival with live music and food trucks to greet those who do. San Ysidro’s pedestrian crossing, where 22 inspection lanes into the U.S. were added this summer, will be open in both directions. The crossing will also remain open on the Mexican side for U.S.-bound cars.Leaders in Baja California’s tourism industry are concerned about the disruption that could continue well past the weekend as some lanes stay closed until November.They already were working to get word out that their tourist spots are safe after the U.S. State Department issued a travel advisory last month that included the region because of violent crime.Ricardo Argiles, CEO of the Rosarito Beach Group, which owns the landmark Rosarito Beach Hotel, said the border closure is a second blow.Reservations for his hotel this weekend are down 30 per cent from last year at this time, and he fears tourism will keep lagging during the construction.Hotels are cutting rates to convince people to still venture south of the border. Rooms at the Rosarito Beach Hotel, once frequented by Hollywood stars like Marilyn Monroe, are going for as low as $60 a night, a 25 per cent drop from last year.The hotel also offers instructions and a Google map on its website that details how to get there after crossing through Otay Mesa.“We hope people still come and once they relax, they forget about the lines,” said Argiles, president of the Hotel and Motel Association of Rosarito Beach.Baja California has been drawing more visitors with growing interest in its picturesque wine country, chic boutique hotels, and booming culinary scene from Tijuana to Ensenada, where restaurants offer Baja-Med cuisine, a blend of Mexican and Mediterranean flavours.The weekend border closure is to allow for the removal of a large metal canopy spanning over all the southbound lanes into Mexico.The crossing will reopen Monday with three southbound lanes while California’s Interstate 5 is realigned to feed into the renovated crossing. U.S. officials expect traffic flows to go back to normal by Thanksgiving, when four of the five lanes at the Western Hemisphere’s largest land crossing will be open.Anthony Kleppe of the U.S. General Services Administration said he is “cautiously optimistic” that the government’s efforts to get the word out about the closure will minimize the hassle.He expects the renovation’s biggest impact to be on the thousands who cross to work and study in San Diego and return each day to their homes in Tijuana.Once complete in summer of 2019, there will be 10 southbound lanes — twice the current number — to handle the estimated 40,000 vehicles that pass through San Ysidro on weekends and 50,000 on weekdays. The expansion also added eight more lanes from Mexico to the United States.last_img read more

Football Torrance Gibson signs letter of intent with junior college

Former OSU redshirt freshman wide receiver Torrance Gibson (6) carries the ball after a reception during the first half of the spring game. Credit: Alexa MavrogianisOhio State wide receiver Torrance Gibson’s future in Columbus was uncertain following his semester-long suspension before the team began its 2016 season in September. On Tuesday, Gibson expressed his desire to play elsewhere, at least for the near future.Gibson signed a letter of intent with junior-college program Mississippi Gulf Coast Community College. A press release sent from a team’s spokesman said Gibson will enroll in the spring.Although Gibson’s signing does show his interest in playing for the Bulldogs, the letter of intent is not binding, meaning he can continue to search for other options, like from other Division I schools. Gibson is eligible to play in 2017 for MGCCC, but would have to sit out a full season if he were to transfer to another Division I school.Gibson, a native of Plantation, Florida, attended American Heritage School and was a member of the 2015 recruiting class. He came out of high school as a four-star dual-threat quarterback and rated the No. 6 athlete in the class by 247Sports.Gibson redshirted his first year at OSU while undergoing a change from quarterback to wide receiver. Gibson shined in the 2016 spring game, scoring twice. OSU coach Urban Meyer said that the wide receiver was “in the mix” for playing time this year before his suspension.“We are looking forward to having Torrance join our football program,” MGCCC coach Chad Huff said in a press release. “We are confident in his abilities on the field and his character off the field, and we expect him to contribute to our team and the Gulf Coast community.Gibson is expected to play quarterback at MGCCC. He made the switch to receiver with OSU after an already deep group at signal caller forced him to make a change.Editor’s Note 12/13: Gibson’s high school has been corrected to American Heritage School. The Lantern originally published that Gibson attended St. Thomas Aquinas High School. read more

Former Buckeye Cameron Heyward juggles academics preparations for NFL

After lining up a job that guarantees a multimillion-dollar contract, the best benefits an employee can hope for and fame and recognition as the newest member of the Pittsburgh Steelers’ dominant defense, it’d be easy to throw away your textbooks and forget lecture halls ever existed. But former Ohio State defensive end Cameron Heyward isn’t taking the easy way out. Even after being drafted in the first round of last month’s NFL draft, Heyward still attends classes and will graduate with a degree in education at the end of this quarter. The motivation to finish college all comes from within. Heyward knows he wants to earn a degree and do something that has not been done before by anyone in his immediate family. “I’m pushing myself,” Heyward said. “I want to impress my family. I’ll be the first one to graduate and that’s just a big accomplishment.” Now that he’s been drafted, his textbooks aren’t the only books he needs to study. Heyward was fortunate to get a playbook from his Pittsburgh coaching staff, something many draft picks weren’t able to do as a result of the NFL lockout. He said the playbook was the first thing he asked for when he arrived in Pittsburgh on April 29. “The playbook is like a magazine,” Heyward said. “I could read it all day, but I’ve still got to look at my textbooks.” Reading his textbooks might not help him a great deal when he’s studying opposing offenses and which quarterback he’ll be trying to sack on Sundays, but it could end up having a bigger impact sooner than he imagined. If the NFL and NFL Players Association don’t reach an agreement on the labor situation, delaying or canceling the season, Heyward said he will take advantage of the opportunity to complete his student-teaching duties. Heyward would be teaching elementary aged children. “I definitely want to do my student-teaching,” Heyward said. “I didn’t get a chance to do it, and I won’t until after my career. But if I can go into that … that’d be so much fun and that’s truly a dream of mine.” If an agreement is reached and Heyward ends up on the field instead of in the classroom, he will get a chance to return to Pittsburgh, where he’s already been welcomed by some of the town’s biggest celebrities. Heyward said Steelers quarterback Ben Roethlisberger called him and wide receiver Hines Ward sent him a text message to congratulate him. With offensive weapons like Roethlisberger and Ward and a defense that has allowed the fewest points in the league two of the past three seasons, Heyward sees no reason why his new team shouldn’t compete for a championship every year. “I like to think we have the best defensive line in the NFL right now,” Heyward said. “It’s unbelievable. We should be in the Super Bowl every year.” Roethlisberger and Ward won’t be the only ones welcoming Heyward to the Steel City — Heyward was born in Pittsburgh and said he still has a lot of family in the area. “It’s like going back to your old stomping grounds,” he said. “I’m very grateful and I feel blessed to be in this situation. Not a lot of players get to say they’re going somewhere that they actually know a lot about. “I get to see my extended family a little bit more. I’m a big family guy and the chance to see them a little bit more, I love it.” Heyward said he’s “ecstatic” about being a Steeler but that it hasn’t yet hit him full force that he will be playing professional football in his hometown. “I’m just an average kid right now,” he said. “It hasn’t really set in to me that I’m going to be a Pittsburgh Steeler yet.” Heyward is just an average kid who stands 6-foot-5 and pushes 300 pounds, plays defensive end for one of the NFL’s elite franchises and goes to class on weekday mornings. read more

Ohio State mens womens basketball launch seasons at Carrier Classic

Some liken sporting events to wars and battles, but the USS Yorktown has seen and fought in the real thing. Sport will converge with the Yorktown, a decommissioned U.S. Navy aircraft carrier, when the Ohio State men’s and women’s basketball teams will open their 2012-13 seasons against Marquette and Notre Dame, respectively, Friday in the Carrier Classic. Friday’s games, which will take place on a court constructed on the Yorktown’s flight deck, bare no likeness to the battles the warship has seen. Still, OSU coach Thad Matta has an appreciation for the venue’s history. The OSU teams and their opponents’ stay on the ship will last for the duration of the 40-minute basketball games. Retired U.S. Navy Lt. Bob Dorsey, 73, of Milton, Fla., recalled that a typical stay as a sailor on the Yorktown was much longer. Unlike for the basketball teams, a “short” stay, or cruise, on the ship would last six to nine weeks. Long cruises could last six to nine months, and the cruises weren’t for basketball games or other forms of pleasure, but for war. Dorsey, a former helicopter pilot and President of the Yorktown Association, was stationed on the Yorktown from 1963-1966 and was twice deployed to Vietnam and the South China Sea. Following World War II, during which the ship faced bombings and other forms of heavy combat, the Yorktown was modified for rooting out the Soviet submarine threat during the Cold War. When it became evident that there was no threat of Soviet submarines in the seas near Vietnam, Dorsey’s mission changed, he said. “We were doing basic utility work, moving men and cargo from different ships in the South China Sea,” Dorsey said. “We were also doing what was considered coastal surveillance. They would send us out to investigate various shipboard targets that they would pick up on our radar and we would fly out to sea if there was a threat. And so that was our primary mission.” Then, the mission changed again once Vietnam “was going pretty big,” Dorsey said. “A lot of (planes) got shot down, so our mission really changed to being combat rescue,” Dorsey said. “During all that time, we never lost a single helicopter due to combat loss, which was pretty spectacular.” And there were many missions that launched on the sea and saw Dorsey and other members of America venture into Vietnamese airspace. The missions, while thrilling, Dorsey said, were exceedingly dangerous and included night missions at low altitude. “You know, flying off an aircraft carrier is probably one of the most exciting things most people ever do, and I thoroughly enjoyed it,” Dorsey said. “We did a lot of night flying, which was fairly dangerous … generally, helicopters were limited to a maximum altitude of 200 feet. So on a dark night at 200-feet, you really better pay attention.” Obviously, OSU won’t face dangers like what Dorsey saw. The biggest risk the two Buckeyes’ squads run on Friday is starting their respective seasons with a loss. For the men’s team, it would be the first opening-game loss since a 76-65 defeat to San Francisco on Nov. 21, 2003. OSU women’s coach Jim Foster has never lost a season opener since arriving in Columbus for the 2002-03 campaign. Given the Buckeyes teams’ history of opening-night success, some fans in Columbus might be disappointed to miss the opener. The Carrier Classic will take place in Charleston, S.C., some 10 hours from Columbus by car. Buckeye Nation will get to see its team play live at the Schottenstein Center again, though. They will return home. In combat on the Yorktown, Dorsey obviously couldn’t make the same guarantee. “As Navy sailors do,” Dorsey said, “you tell your family, ‘Goodbye. I’ll see you when I get back.’” Matta conveyed appreciation for the sacrifice of the Yorktown’s crews during OSU’s Oct. 11 media day. “(The Carrier Classic is) something that these young men, for the rest of their lives, will remember,” Matta said. “Obviously I want to win the basketball game, but that is one game that is more than the game of basketball. People forget we got guys fighting the war for us right now.” OSU women’s basketball is scheduled to tip off its Carrier Classic game against Notre Dame at 4 p.m. on Friday. The OSU men will tip off against Marquette at 7 p.m. Yorktown takes a starring role The Yorktown has enjoyed Hollywood limelight in her day, having served at the movie set for the movies “The Fighting Lady” and “Tora! Tora! Tora!” (1970). She was also featured in the TV series “Get Smart” (1968) and on the SyFy Channel’s “Ghost Hunters” (2012). Yorktown aids in space exploration On Dec. 27, 1968, the Yorktown recovered the astronauts aboard NASA’s Apollo 8 spacecraft, the first manned spacecraft to travel to the vicinity of Earth’s moon and return safely, according to a Carrier Classic release. Apollo 8 Commander Frank Borman, Command Module Pilot James Lovell and Lunar Module Pilot William Anders splashed down in the Pacific Ocean before a Yorktown helicopter arrived to scoop the astronauts out of the ocean.

Christian Eriksen Spurs need to get back on track immediately

first_imgTottenham playmaker Christian Eriksen has urged the team to bounce back immediately after their 100% start to the season ended in a 2-1 loss to Watford on SundayThe Lilywhites went ahead at Vicarage Road through Abdoulaye Doucoure’s own goal in the first half.But headers from Troy Deeney and Craig Cathcart handed Watford all three points and maintained their 100 per cent start to the season, whilst ending Spurs’ in the process.“We’re very disappointed,” Eriksen told the club website.“We want and expect to win every game and losing is not something we often do, luckily.“We need to get back on track and do that against Liverpool. That’s the perfect occasion to come back and we’ll do that.”Cristiano Ronaldo, Nemanja Vidic, Manchester UnitedVidic: “Ronaldo is the most professional footballer I’ve seen” Andrew Smyth – September 14, 2019 Nemanja Vidic opened up on how a 21-year-old Cristiano Ronaldo’s professionalism left him stunned at Manchester United.Sunday’s defeat was Spurs’ first in the Premier League for 43 games after taking the lead, which last came back in November 2016 against Chelsea.“It’s not something that often happens to us,” said Eriksen.“That’s what everyone felt, everyone had the feeling that they were not going to score but they got a free-kick in a dangerous place, a decent cross and a good header,” he added.“We had chances, didn’t finish the game and they scored from two set-pieces – we can’t be satisfied with that.“The result against United (3-0 last week) was exceptional but we’re down to earth again. This is football, anything can happen in any game, it goes so quickly with ups and downs.”Spurs will next face Liverpool at Wembley on September 15.last_img read more
