Metabolizable Energy and Chemical Composition of Poultry by-Product Meal
This study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (PBPM) from two slaughterhouses in Iran. Samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. The amounts of calcium, phosphorus, sodium, potassium, Magnesium, Iron, Manganese, copper and Zinc were determined. The apparent metabolizable energy (...
متن کاملComparative Analysis of Fatty Acid Composition of Yolk Lipids in Indigenous and Conventional Chicken Eggs
Eggs of the indigenous laying hens are preferred by consumers to those obtained from commercial breeds. The present study aimed to compare the fatty acid (FA) composition of yolk lipids of indigenous eggs (Indigenous; n = 20) and conventional eggs (Conventional; n = 20). Indigenous and conventional eggs were collected from Lori layer hens reared under free-range condition and an commercial farm...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولChemical composition, true metabolisable energy content and amino acid availability of grain legumes for poultry
Samples of sweet yellow lupins (Lupinus luteus; n = 4), broad leaf lupins (Lupinus albus; n = 12), narrow leaf lupins (Lupinus angustifolius; n = 8), faba beans (Vicia faba; n = 2), field peas (Pisum sativum; n = 4) and narbon beans (Vicia narbonensis; n = 2) were collected over a two-year period. The physical characteristics (thousand seed and hectolitre mass), chemical composition (dry matter...
