—Lancaster Farming, Saturday. September 14.1968 16 Broiler Diet Research Shows Meat & Bone Meal Economical And Effective Adding up to 10 percent meat and bone meal to broiler diets is both economical and effective. Recent research by Thomas D. Runnels, associate professor in the department of animal sci ence and agricultural biochemis ts at the University of Dela ware, shows it can be used at higher levels than previously be lieved At the present time, most com mercial bi oiler feeds contain less than five percent meat and bone meal. Nutritionists recom mended such low levels because they believed higher calcium levels supplied by meat and bone meal might have a depress ing effect on broiler growth and their use of feed In a previous study by Sathe and Clymont (1964), high calci um levels tended to depress growth when small amounts of meat and bone meal were used in the total protein supplement However, this growth depiessing effect of calcium was not observ ed when meat and bone meal was the majoi source of diet pro tein Runnels believes this sug gests that other dietary sources of calcium may have been re sponsible foi the giowth depres sion Runnels’ study showed con clusively that the high level of calcium and phosphorus contrib uted by meat and bone meal has no ill effects on broilei weight gain and feed utilization if diet ereigy and essential ainino acid lev els-are maintained Broiler quality remained high when meat and bone meal was used, according to Runnels Ob servations on live buds showed no diffeience in grade, peiosis, bieasl blisters 01 other condi tions Substituting fish meal, distill ei s dark grains or meat and bone meal in the basic corn-soybean diet improved broiler growth On 7 5 percent meat and bone meal, broilers average weight was 4 64 pounds in nine weeks compaied to 424 pounds foi a coin-soybean meal diet With thiee peicent fish meal added weights averaged 442 pounds, on 10 percent distilleis daik giains, they aveiaged 456 pounds Thus, the greatest gains were observed with broilers receiving the largest peicentages of meat and bone meal in their diets Runnels points out that this is particularly important since the cost of this ration was the low est of any tested Least cost com puter diets containing up to 10 percent meat and bone meal re duced the feed ingredient costs from $1 to $2 50 per ton com pared to other feed costs at the same nutrient levels Approximately four billion pounds of high protein meals aie produced annually from animal by-products in the United States Despite the extreme variability in raw material used for produc ing these meals (fat trimmings, waste fat, bone, packing-house oftal, fallen animals, etc), the finished product has a reason ably uniform composition Close process control and the relative ly low temperature to which the product is exposed—24o-degrees F or less in most plants—helps prevent any significant loss In nutritive quality from heat dam age to the essential amino acids The high protein meals aie ex cellent sources of calcium and phosphorous as well as some of the water soluble vitamins Runnels conducted four ex- periments to evaluate'meat and bone meal in bi oiler diets. The .chicks used in all four tests were white broiler crosses bought from the same commercial hatchery. In the firrt experiment they were sexed cockerels; in the other three experiments, th-y were sexed, but both sexes were used Chicks were thoroughly ran' READY FOR MARKET... in record time!

This precaution was in addition to obtaining all chicks for each test from the same breeder flock. Chicks were kept in tjie start ing batteries for the first four to five weeks and then transferred to growing batteries for the rest of the test period. Starter feed was provided for all chicks for the first four to five weeks. At this time, the chicks were weigh* ed, starter feeds removed and finishing feeds provided. These finishing diets were similar but were computed to a lower amino acid level and contained approx- Atglen imately 2.5 percent less protein than the startor feeds. Formulas for the first two ex periments were prepared with a computer, ail based on the same nutrient requirements. In the first experiment, fish meal, dis tillers dark grains and meat and bone meal were used; in the sec ond, fish meal and meat and bone meal were, used. Commer cial broiler feeds were used for the remaining two experiments. All feeds were reduced to a uni form feed mix to prevent chicks selectively choosing ingredients. Runnels states that broiler di ets containing up to 1.3 percent calcium and 1.0 percent phos phorus, mostly from bone in the meat and bone meal, produced results equal in all respects to those from diets containing low- SURE you want to get your steers to market fast.
