effects of condensed tannins (ct) on crude protein availability in sainfoin hay was investigated according to most popular ruminant feeding systems. different treatments including polyethylene glycol (6000 mw), sodium hydroxide, sodium bicarbonate, potassium permanganate, wood ash, water and urea, were applied for deactivation of ct crude protein fractioning was determined using nylon bag techn...

The objective of this study was to evaluate the effect adding exogenous enzymes diet on nutrient intake and digestibility, nitrogen balance, ingestive behavior rumen movement ewe lambs. Five lambs, Dorper x Santa Inês crossbred, with an average age 7 ± 1 months, weight 36.40 2.36 kg were assigned in a 5x5 Latin square design. treatments consisted concentrate: Allzyme, Fibrozyme®, Amaize®, Mix C...

an experiment was conducted to predict the true metabolizable energy (tmen) of compounded starter feeds of broiler chickens trough their chemical composition using precision-feeding method of sibbald in male boilers. in the first, eight compounded feed samples provided from eight feed plants and their chemical composition determined in laboratory. results of chemical composition showed that ave...

The amount of nitrogen gas (N2) available for microbial protein synthesis via nitrogen fixation in the rumen was estimated. Measurements were made of nitrogen fixation by ruminal ingesta from goats fed low protein rations for a prolonged period of time, and by ingesta from sheep fed high protein rations. Nitrogen fixation by rumen microorganisms incubated for 30 or 180 min in vitro was measured...

The true digestibility of amino acids of 5 groups of different Trifolium varieties and hybrids was established by using the balance method adapted for geese. Digestibility of the most important amino acids Lysine varies from 70.40 (for tetraplod red clover) to 81.78 (for medium leafy white clover varieties); for Methionine from 60.54 (for Trifolium repens f. giganteum) to 89.42 (diploid red clo...

The objective was to determine the values of apparent metabolizable energy (AME) and corrected for nitrogen balance (AMEn) roasted in natura amaranth grains. A breeding stock 108 female Japanese quails (Coturnix coturnix japonica) with an initial age 29 days used. birds were distributed a completely randomized design three treatments six replications, per experimental unit. used reference diet,...

Sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). Diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, T1), 35% wheat straw (T2), 35% barley straw (T3) or 35% maize straw (T4). Total-tract apparent digestibility for dry matter, organic matter...

The following characteristics were determined in raw and popped amaranth grain: crude protein (158.1 and 168.5 g/kg), ether extract (71.5 and 69.4 g/kg), neutral detergent fibre (NDF) (99.2 and 111.8 g/kg), cellulose (86.6 and 60.0 g/kg) and essential amino acids (Cys 4.2 and 4.1, Thr 6.0 and 6.5, Ala 8.8 and 9.2, Val 6.8 and 7.4, Ile 5.2 and 5.6, Lys 9.2 and 8.8, Arg 12.8 and 14.2 g/kg). In vi...

In order to investigate the effect of different levels of niacin supplementation on growth, nutrient utilization, their balance and blood biochemical profile, 15 male buffalo calves (9-10 months of age, 88.4±4.37 kg average body weight) were divided into 3 equal groups each of 5 calves, following a completely randomized design, and fed individually for 120 days with wheat straw and concentrate ...
