16 CALF News • February | March 2022 • www.calfnews.net Beyond those numbers, Jones says feed conversion, while not quite as good as quality beef steers, was much better than straight Holstein steers, and the F1s had about 6 percent more days on feed. But the hybrids had better yield grades than straight beef steers. “So our yield grades were going lower and our quality grades were going higher. We were getting more Choice and Prime with less fat,” he says. “And we’ve made significant progress in the last five years, moving up into where we’re much better than the commodity cattle here in the yard,” Jones says. Those type of cattle generally grade around 70 percent Choice, maybe a little better. What’s more, according to research conducted by Texas Tech University with beef-on-dairy steers at Hy-Plains Feedyard’s Research Center, the crossbreds performed well in consumer sensory tests.“In the consumer sensory panel, the most tender was a straight dairy steer,” according to the research report. But the beef-on-dairy cross produced more tender steaks than beef steers. “On juiciness, we were slightly more juicy,” Jones says. The beef-on-dairy cattle at Hy-Plains are marketed to packers on a grid “and we’re getting a bit of a premium for them,” Jones says. Connecting the Dots At the moment, agreements to produce and buy beef-on-dairy calves happen between individual feedyards and individual dairies. However, Dorn says ABS is developing a program to help feedyards and dairies connect the dots on a bigger scale. “We’re just on the cusp of creating that actual program,” he says. “We’ll work on lots of different agreements with different feeders, different packers.” Dairy producers are numbers nuts just as much as feedyard folks. So they can identify the top cows in their barn and breed those to sexed semen to produce replacement heifers. The rest of the cows could be bred to beef bulls and produce a calf with much higher value than a straight Holstein. “Anywhere from $60 to $100 [per head] is what a dairy calf is worth,” Dorn says. “These [F1] calves are worth $200 and I’m hearing as high as $285 for a day-old calf.” And some dairies are retaining ownership in the crossbred calves to realize the full value of the beef-on-dairy cross. Unlike a straight Holstein calf that will be on feed for a year or more, the beef-ondairy crosses can be handled more like a beef steer. After a stay at a calf ranch, “We’re growing a lot of these composites in a typical grow yard program,” Jones says, and the cattle are going on feed around 800 pounds. What’s more, the beef-on-dairy crosses are available 52 weeks a year, Dorn points out. That takes away the seasonality with spring and fall weaning. As the beef-on-dairy trend has grown, some have wondered if the F1 crosses are putting more tonnage into the beef market. According to Jones, however, the opposite may happen. Those dairy steers are part of the fed beef marketing mix already. “We’re able to market these cattle [F1 crosses] at a lighter weight.” Rather than pressure the entire beef market, Jones thinks the price pressure will be put on commodity cattle. The carcass quality is much better than that from a high-risk commodity steer. “When we can make these cattle grade 91 percent Choice, we’ll grow that chain,” Jones says. “We’ll get more as we go forward out of these cattle. We’ve done it in straight beef cattle and we’ll do it in these as well.” According to Dorn, “What we’re doing to the average beef producer is raising the quality bar they have to compete with. We think there’s opportunity to influence more than 5 million calves going into the beef supply chain.” Jones agrees.“We’re growing. It really has the potential to be a branded product.” BEEF WITH A SIDE OF DAIRY Continued from page 12 Each mL contains 300 mg of oxytetracycline base (equivalent to 323.5 mg of oxytetracycline dihydrate). For Use in Beef Cattle, Non-lactating Dairy Cattle, Calves, Including pre-ruminating (veal) calves BRIEF SUMMARY (For full Prescribing Information, see package insert.) INDICATIONS: NOROMYCIN 300 LA is intended for use in treatment for the following diseases when due to oxytetracycline-susceptible organisms: Beef cattle, non-lactating dairy cattle, calves, including pre-ruminating (veal) calves: NOROMYCIN 300 LA is indicated in the treatment of pneumonia and shipping fever complex associated with Pasteurella spp., and Histophilus spp. NOROMYCIN 300 LA is indicated for the treatment of infectious bovine keratoconjunctivitis (pink eye) caused by Moraxella bovis, foot-rot and diphtheria caused by Fusobacterium necrophorum; bacterial enteritis (scours) caused by Escherichia coli; wooden tongue caused by Actinobacillus lignieresii; leptospirosis caused by Leptospira pomona; and wound infections and acute metritis caused by strains of staphylococcal and streptococcal organisms sensitive to oxytetracycline. Swine: NOROMYCIN 300 LA is indicated in the treatment of bacterial enteritis (scours, colibacillosis) caused by Escherichia coli; pneumonia caused by Pasteurella multocida; and leptospirosis caused by Leptospira pomona. In sows NOROMYCIN 300 LA is indicated as an aid in control of infectious enteritis (baby pig scours, colibacillosis) in suckling pigs caused by Escherichia coli. PRECAUTIONS: Exceeding the highest recommended level of drug per pound of bodyweight per day, administering more than the recommended number of treatments, and/or exceeding 10 mL intramuscularly or subcutaneously per injection site in adult beef cattle and non-lactating dairy cattle and 5 mL intramuscularly per injection site in adult swine, may result in antibiotic residues beyond the withdrawal time. Consult with your veterinarian prior to administering this product in order to determine the proper treatment required in the event of an adverse reaction. At the first sign of any adverse reaction, discontinue use of the product and seek the advice of your veterinarian. Some of the reactions may be attributable either to anaphylaxis (an allergic reaction) or to cardiovascular collapse of unknown cause. Shortly after injection treated animals may have transient hemoglobinuria resulting in darkened urine. As with all antibiotic preparations, use of this drug may result in overgrowth of non-susceptible organisms, including fungi. The absence of a favorable response following treatment, or the development of new signs or symptoms may suggest an overgrowth of non-susceptible organisms. If superinfections occur, the use of this product should be discontinued and appropriate specific therapy should be instituted. Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving NOROMYCIN 300 LA in conjunction with penicillin. WARNINGS: Warnings: Discontinue treatment at least 28 days prior to slaughter of cattle and swine. Not for use in lactating dairy animals. Rapid intravenous administration may result in animal collapse. Oxytetracycline should be administered intravenously slowly over a period of at least 5 minutes. CAUTION: Intramuscular or subcutaneous injection may result in local tissue reactions which persists beyond the slaughter withdrawal period. This may result in trim loss of edible tissue at slaughter. Intramuscular injection in the rump area may cause mild temporary lameness associated with swelling at the injection site. Subcutaneous injection in the neck area may cause swelling at the injection site. ADVERSE REACTIONS: Reports of adverse reactions associated with oxytetracycline administration include injection site swelling, restlessness, ataxia, trembling, swelling of eyelids, ears, muzzle, anus and vulva (or scrotum and sheath in males), respiratory abnormalities (labored breathing), frothing at the mouth, collapse and possibly death. Some of these reactions may be attributed either to anaphylaxis (an allergic reaction) or to cardiovascular collapse of unknown cause. To report a suspected adverse reaction call 1-866-591-5777.
