Effect of Dietary Crude Fiber on Endogenous Dry Matter and Nitrogen Excretion in Cockerels
GEORGIEVA, V., S. CHOBANOVA, N. TODOROV and D. PAVLOV, 2014. Effect of dietary crude fiber on endogenous dry matter and nitrogen excretion in cockerels. Bulg. J. Agric. Sci. 20: 903-908 The experiments were carried out with 10 cecectomisеd cockerels for each diet. They are force fed by method of Sibbald (1986) with nitrogen free diets of pure nutrients and with sunflower meal with different cru...
متن کاملDietary protein effects on hen performance and nitrogen excretion.
Because dietary nitrogen intake affects nitrogen content in manure, diet management has been recognized as a means to reduce ammonia emissions from poultry operations. The objectives of the present research were 1) to determine the extent to which the CP content of laying diets can be reduced, based on performance criteria, and 2) to determine how ash:nitrogen ratios of manure, eggs, and hens a...
متن کاملEffects of dietary protein level on growth performance and nitrogen excretion of dairy heifers
OBJECTIVE Protein supplementation is costly and can result in excess nitrogen (N) excretion. The objective of this study was to evaluate the effects of feeding different levels of dietary protein on average daily gain, body size, rumen fermentation, and nitrogen excretion of 8 to 10 month-old Holstein heifers. METHODS Thirty-six Holstein heifers were divided into 12 blocks according to age (2...
متن کاملStudies of Urea Excretion. Ix. Comparison of Urea Clearances Calculated from the Excretion of Urea, of Urea plus Ammonia, and of Nitrogen Determinable by Hypobromite.
According to the usually accepted concept, the urea removed from the blood by the kidneys is excreted in two forms, chiefly as urea itself, but partly as ammonia. That the ammonia of the urine is formed in the kidneys was demonstrated by Nash and Benedict (1921), in work which has been confirmed by other authors (cf. Peters and Van Slyke, I, p. 373). Evidence from animal experiments in v4vo has...
