An optimal dietary non-phytate phosphorus level of broilers fed a conventional corn-soybean meal diet from 4 to 6 weeks of age.
It is imperative to evaluate precise nutrient requirements of animals in order to optimize productivity and minimize feed cost and nutrient excretions. The current non-phytate phosphorus (NPP) recommendation for broilers is based on the papers published 30 years ago. However, today's commercial birds are quite different from those before 30 years. Therefore, the present experiment was conducted...
متن کاملRelative bioavailabilities of organic zinc sources with different chelation strengths for broilers fed a conventional corn-soybean meal diet.
An experiment was conducted to estimate relative bioavailability of Zn in 3 organic zinc sources with different chelation strength (Q(f)) compared with ZnSO(4). A total of 1,092, 1-d-old male broiler chicks were assigned randomly to 6 replicate cages (14 chicks per cage) for each of 13 treatments. Dietary treatments included the basal corn-soybean meal diet (27.82 mg of Zn/kg of DM) supplemente...
متن کاملThe chemical characteristics of organic iron sources and their relative bioavailabilities for broilers fed a conventional corn-soybean meal diet.
Twenty-four organic Fe sources were evaluated by polarographic analysis and via solubility in buffers (pH 5 and 2) and deionized water. Organic Fe sources included 6 Fe-Met complexes (Fe-Met), 10 Fe-Gly complexes, 1 Fe-Lys complex, 4 Fe proteinates, and 3 Fe-AA complexes (Fe-AA). Sources varied considerably in chemical characteristics. Chelation strengths (quotient of formation [Q] values) rang...
متن کاملSunflower Meal and Enzyme Supplementation in Diets of Broilers from 21 to 42 Days of Age
The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...
متن کاملEffect of Using Enzyme Complex on Productivity and Hatchability of Broiler Breeders Fed a Corn-Soybean Meal Diet
A total number of 5520 female and 480 male breeders (Arbor Acres plus) at 42wks of age were used in a 10-week-trial to investigate the effect of an enzyme complex on the quality and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. There were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...
