Abstract
This experiment was designed to determine the effect of spray dried animal plasma (SDAP) on digestibility of a corn-soybean meal diet in Ross 308 male broiler chicks. Two corn-soybean meal diets were formulated, a Control diet and one with 2% SDAP. Treatment (Trt) 1 and 2 were fed the Control and SDAP diet for 10 d while Trt 3 and 4 were fed the Control and SDAP diet for 21 d. Growth performance and nutrient digestibility was determined at 10 d and 21 d. By d 21, dietary treatment did not affect (P > 0.10) growth performance (BW, FI, G/F). At both 10 d and 21 d, SDAP improved (P < 0.05) digestibility of AMEn, DM and organic matter (OM). Digestibility of EE was reduced (P < 0.05) on d10 but not (P > 0.10) on d21. The addition of SDAP improved (P < 0.05) Cys digestibility on d 10 while on d 21 the addition of SDAP improved digestibility of Pro, Ala, Cys, Leu, Thr, Trp, Tyr, Val (P < 0.05) and Ser (P < 0.10). Previously published amino acid digestibility coefficients (determined in 21 d chicks) for individual ingredients (corn, soybean meal and SDAP) were used to calculate expected AA digestibility of the experimental diets and then compared to 21 d digestibility coefficients measured in the current experiment. Cystine digestibility (21 d) in the SDAP fed chicks was greater (P < 0.10) than that expected based on digestibility coefficients of individual ingredients. These data demonstrate that SDAP is a highly digestible ingredient in broiler chick diets, and it may improve digestibility of a corn-soybean meal diet fed to broiler chicks.
期刊介绍:
The Journal of Applied Poultry Research (JAPR) publishes original research reports, field reports, and reviews on breeding, hatching, health and disease, layer management, meat bird processing and products, meat bird management, microbiology, food safety, nutrition, environment, sanitation, welfare, and economics. As of January 2020, JAPR will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers.
The readers of JAPR are in education, extension, industry, and government, including research, teaching, administration, veterinary medicine, management, production, quality assurance, product development, and technical services. Nutritionists, breeder flock supervisors, production managers, microbiologists, laboratory personnel, food safety and sanitation managers, poultry processing managers, feed manufacturers, and egg producers use JAPR to keep up with current applied poultry research.
