three experiments were conducted to study metabolizable energy, protein quality and chemical composition of four blood meal (bm) samples from local animal rendering plant during 20 days sampling. all experiments were designed in a completely randomized design. the result of first experiment showed that chemical composition averages of bm samples were: dm, 88.43; cp, 77.03; ee, 1.12; ash, 5.01; ...

one hundred twenty male broiler chickens of 20 d of age were used to study the effect of enzyme supplementation on the apparent metabolisable energy corrected for nitrogen in corn, wheat and triticale using total excreta collection or marker methods. the average apparent metabolisable energy corrected for nitrogen in corn, wheat and triticale on dry matter basis, were 3480 ±90, 3263 ±61 and 326...

three experiments were conducted to study the chemical composition and the effect of variety, cultivation area as well as enzyme supplementation on the apparent and true metabolisable energy of triticale. in the first experiment, the precision-fed rooster assay was employed to determine the true metabolisable energy corrected for nitrogen in triticale. in the second and third experiments, total...

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...

Three experiments were conducted to evaluate the effect of β-mannanase BM: supplementation on the performance, metabolizable energy, amino acid digestibility, and immune function of broilers. A total of 1,600 broilers were randomly distributed in a 4 × 2 factorial arrangement (4 nutritional levels × 0 or 500 g/ton BM), with 10 replicates and 20 broilers per pen. The same design was used in the ...

objective: the aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (cgm) and its effect on growth performance of broiler chicks. methods: chemical composition and nitrogen corrected true metabolizable energy of cgm was determined by standard and precision-fed cockerel assay methods.  for evaluating of protein quality, 90 male broiler chicks in a com...

this study was carried out to determine regression equations for prediction of apparent metabolizable energy corrected by nitrogen (amen) using 11 barley cultivar (valfajr, karon, bahman, aras, dasht, afzal, zarjo, kavir, reihani, makui and yousef) the seeds obtain from alborz province, iran. all of the cultivar were analyzed based on proximate analysis, starch, ndf and adf. result showed that ...
