In this experiment 144 Hy-line (W36) laying hens, 65 to 77 weeks of age were separated into 4 treatments with 3 replicates (12 birds per replicate) in a completely randomized design experiment. The grass clipping wastes incorporated into a complete formulated layer diet, consisting on a corn and soybean based diet, were 0, 1.5, 3.0 and 4.5% in 1 to 4 experimental groups. The results showed that...

This study was conducted to determine the effects of adding ethanol extract of propolis (EEP) and cumin essential oil (CEO) to diets of broiler chicks on the performance, blood parameters, immune response and carcass traits. A total of 240 day-old Ross-308 broiler chicks were randomly allocated to four treatments with six replicates and 10 birds in each replicate in a completely randomized desi...

Sixty multiprious Holstein cows were fed treatment diets from 11 to 40 d postpartum with corn silage as the forage. Treatment diets each contained a different supplemental protein: 1) solvent soybean meal; 2) extruded soy product; 3) combination of corn gluten meal and distillers dried grains with solubles; and 4) a combination of protein sources from diets 2 and 3. Covariate adjusted means for...

The objective of the current study was to evaluate the effect of a subtilisin protease, without or with inclusion of carbohydrases, on digestibility and retention of energy and protein, as well as the solubilization and disappearance of non-starch polysaccharides (NSP) from corn-soybean meal based diets fed to broiler chickens. Two hundred eighty-eight Ross 308 male broiler chickens were used f...

three experiments were conducted to evaluate the nutritional value of bitter vetch. experiment 1 was conducted to determine the metabolisable energy content of bitter vetch. sixteen adult leghorn roosters were used. forty grams of bitter vetch were precision-fed individually to 12 roosters. in addition, 4 birds were not fed and served as a control treatment in the measurement of metabolic fecal...

The objectives of this study were to expand the database and determine the intestinal digestibility of rumen undegradable protein (dRUP) of common dairy feeds and to determine the effects of feeding 37.9% wet corn gluten feed on these estimates. Two ruminally and duodenally fistulated steers were assigned randomly to a crossover design with 4-wk periods. The mobile bag technique was used to det...

effects of supplemental phytase and xylanase in a corn-soybean meal based diet containing 250 g/kg wheat bran, were investigated. on broiler performance and phosphorus degradability and nitrogen digestibility. phytase (500 and 1000 ftu) and xylanase (2700 and 5400 exu) individually and in combination were added to the basal diet and given to 6 replicate groups (4 birds per replicate). at 21...
