A New Precision–Fed Chick Assay for Determining True Metabolizable Energy Values of some Poultry Feed Ingredients for Broiler Chickens
Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...
متن کاملthe available energy values of fats for broiler chickens at 42 days of age
an experiment was conducted to determine the effect of different inclusion rates and degree of saturation of fat sources on true metabolizable energy corrected to zero nitrogen retention ( tmen) values in broiler chickens at 42 days of age. animal fat and cotton seed oil were blended in the proportions of: 0.25:0.75 , 0.50:0.50 , 0.75:0.25. the three blends together with the animal fat and cott...
متن کاملDetermination of Apparent and True Digestibility of Poultry by Product Meal in Broiler Chickens
In order to determination of ileum apparent and true digestibility of two samples of poultry by product meal, an experiment was conducted with a total of 60 day-old broiler chicks, Ross 308 strain. Poultry by-product meal was prepared from two slaughter house in Alborz province. Samples were sent to laboratory for determination of chemical analysis. The birds received commercial broiler starter...
متن کاملApparent metabolizable energy of glycerin for broiler chickens.
Three energy balance experiments were conducted to determine AMEn of glycerin using broiler chickens of diverse ages. In experiment 1, two dietary treatments were fed from 4 to 11 d of age. Dietary treatments consisted of a control diet (no added glycerin) and a diet containing 6% glycerin (94% control diet + 6% glycerin). Four dietary treatments were provided in experiment 2 (from 17 to 24 d o...
متن کاملEstimation of metabolizable energy equivalency of Bacillus Subtilis spore for male broiler chickens
There are many studies on the effects of probiotics on performance of broiler chickens, but none of them has evaluated the metabolizable energy (ME) equivalency values of probiotics. The aim of this study was to determine the metabolizable energy equivalency value of Bacillus subtilis spore and its potential for decreasing feed ME content and cost. One hundred seventy-six day-old male broilers ...
