F3o*Lancaster Fanning, Saturday, January 9,1993 «r- Livestock Notes Does A Maternal Milk EPD Really Mean More Milk Production? John W. Comerford Penn State Beef Specialist Beef producers are often con fused about the use of the maternal milk EPD in beef selection. After all, how can something reported in pounds of weaning weight actual ly mean more milk production? A couple of recent research reports have confirmed that selec tion for higher maternal milk EPD does indeed result in higher milk production as well as higher weaning weights. A South Dakota State University study compared daughters of high and low EPD sires for maternal milk. They found the higher EPD sires pro duced daughters that liad more daily milk production and calves with heavier weaning weights. A second study at Virginia Tech University compared heifers and cows from sires that were selected as: high milk + high year ling wt., low milk + high yearling wt,, high milk + low yearling wt. and low milk + low yearling wt They also found that selection for higher milkEPDs results in higher actual milk production and hea vier weaning weights in daughters of these sires. In fact the latter study found that a 1 percent increase in milk production accounted for about 2 pounds of DRASTIC FUEL COST REDUCTIONS With This Attractive Outside Wood & Coal Heating System Protect your bottom line profits The best way to protect pigs—and profits—from respiratory diseases is with Schenng-Plough’s family of AR-PAC® vaccines Here’s why • First US DA licensed rhinitis vaccines • Filiated anti attachment atrophic rhinitis technology • Lets you opt for broad range respiratory disease control or target specific diseases • Combines unparalleled rhinitis protection with a choice of defenses against erysipelas, pneumonia, parasuis and mycoplasma profit-robbers • Available in convenient multiple dose vials Your choice of profit-protection AR-PAC vaccines is available now at ANIMAL HEALTH SALES, INC.

But using data like this in a selection program for increasing milk production in the herd is not without its pitfalls. One problem, in our environment anyway, may be too much milk. There is a decreasing return to calf growth with increased milk production. That is, the growth response to increased milk production levels off once a sufficient amount of milk is available. Secondly, there must be some genetic potential for growth in order for the calf to use the increased milk. Finally, it takes feed to produce milk and we must be aware that heavier milking cow have increased nutritional require ments, particularly for protein. However, the South Dakota study showed that production efficien cy, measured as the ratio of feed energy to pounds of weaned calf, was greater for cows with heavier milk production. Information is available to increase milk production in any beef herd and it will increase the efficiency of production as well. But before making any selections, consider the additional costs of production and other genetic values. Take Care In Handling Your Livestock More than 50 percent of all bruises in slaughter livestock are caused by rough careless hand ling. The most common cause of bruising sheep/lambs is grabbing the lamb by the wool or by the nind leg- more than 25 percent of lamb bruises occur on the hind leg while 17 percent occur in the loin area. A bruise results from a blood vessel hemorrhaging under the skin/hide. The outside of the ani mal can appear normal even when there is a large injury under the hide. Unless you sell on a carcass basis, you may never know if you are selling livestock with bruises. Bruised meat is not supposed to be used for human consumption. According to a recent report, $46 million annually is lost from bruises on cattle and hogs. Some hints to aid in handling livestock: • Try to exercise patience in loading or when working with livestock. Let them move at their own pace.

ASI requested this yield and quality grade system to give the lamb industry a value-based mark eting tool that provides an incen tive to produce lean consumer pre ferred lambs. They believe that current marketing structure encourages fat rather than lean. Proposed revisions to the grad ing standards are: • Require that ovine carcasses be identified for quality and yield grade when officially graded • Require that most of the kid ney and pelvic fat be removed Quality and Safety Features 800-858-WASH or (215) 689-8850 prior to grading cannot be over 1 percent of carcass weight * Shift and narrow the fat thick ness range in each yield grade * Eliminate consideration of leg conformation score in determin ing the yield grade. The proposed standards incor porate one component of the USDA yield grade standards of 1982, utilizing fat thickness over the loin eye at the 12/13 rib. Yield grade is basically deter mined by fat thickness as follows: Yield Grade 1 = up to 0.15 inches: Yield Grade 2 = 0.16 to 0.25 inches; Yield Grade 3 = 0.26 to 0.35 inches; Yield Grade 4 = 0.36 to 0.45 inches; Yield Grade 5 = > 0.46 inches. This is some of the basic infor mation included in the AS I proposal. WIN POWER WE WELCOME YOU TO VISIT US AT BOOTHS 466 & 467 MAIN FLOOR - PA FARM SHOW ATTENTION FARMERS.
