21 Three levels of metabolizable protein supply (108, 98–95 and 85 g PDIE kg DM) (PDIE: protein digested in the small intestine when rumen-fermentable energy is limiting) in the diet and three levels of difference between rumen-degradable 21 energy and N (PDIE 2 PDIN 5 0, 10 and 20 g kg DM) (PDIN: protein digested in the small intestine when rumenfermentable nitrogen is limiting) were used in t...

Alternative ingredients can be adequately used in poultry feeds as long the energy values and nutrient digestibility have been previously determined. For example, brewer’s grains olive pomace waste, which are residues of food industry, potential animal feed. This study was conducted to determine metabolizable (ME), nitrogen-corrected ME (MEn), ileal digestible (IDE) waste for broiler chickens u...

eight male lambs each aged approximately 11 months and having a body weight of 32.5 ± 2.5 kg were selected as experimental samples in the ongoing experiment. for the supplemented group, monensin was fed at 22 mg/lamb per day. relationships between dietary characteristics and fecal as well as urinary nitrogen losses were examined using data from the two treatments. microbial n production was est...

an experiment was conducted to study the effect of metabolizable energy (me) and protein of japanese quails diets on offspring performance and antibody production against sheep red blood cell (srbc). a total of 432 japanese quails (13 week-old) were divided into nine treatments. each treatment comprised four replicates of twelve birds (9 female and 3 male). nine diets including three levels of ...

The digestible protein requirements of lactating ewes were studied with Chios 3 ewes during the declining state of lactation in two nitrogen balance and three feeding trials. A 60 kg ewe producing 1.0 or 2.0 kg milk of 6% protein and maintaining weight equilibrium, required 134 and 230 g digestible protein daily, respectively. These requirements were obtained with ewes receiving 110 Kcal metabo...

Twelve goats of the Granadina breed in mid- and late lactation were used in two consecutive years to determine their protein and energy requirements for lactation. The animals were individually fed on diets based on pelleted lucerne (Medicago sativa) hay and barley. A total of six balance experiments were carried out. Gas exchange was measured using open-circuit respiration chambers. Milk yield...
