The brown seaweed Sargassum illicifolium is abundant along the Iranian coastline of the Oman Sea in which is rich in nutrients. The aim of the present study was to test the hypothesis which it can be used as a source of protein in shrimp diets. The experiment was conducted in a laboratory, 2013, where 3g shrimp juvenile acclimation in a 5000L tank. They were then kept in plastic tank containing...

The objective of this study was to investigate the effect of dietary protein levels on pullet development and egg production performance of local hens. One hundred sixty local chicken pullets were used in this study. During the rearing period, the pullets were divided randomly at a density of 16 chicks per cage in rearing pens. During week 1, all birds were fed a starter diet containing 19% cru...

Eight ruminally cannulated multiparous Holstein cows that were part of a larger production trial were used to study the effects of varying dietary ratios of alfalfa silage (AS) to corn silage (CS) on omasal flow of nutrients and microbial protein. Cows were blocked by DIM and randomly assigned to 2 replicated 4 x 4 Latin squares (28-d periods). Diets fed contained (dry matter basis): A) 51% AS,...

the aim of this study was to evaluate the effects of balancing low protein diets for methionine and lysine on performance of early lactation holstein cows under hot environmental temperature. twenty one multiparous holstein cows in early lactation were allocated to three experimental rations including, 1) high protein ration with 17.5% cp, 2) medium protein ration with 16% cp and 12 g/d rumen p...

sixty eight holstein cows, 38 primiparous and 30 multiparous ones, were employed in a randomized complete block design, blocked to evaluate the effects of 2 diets in various ruminal fermentable carbohydrate sources (ground corn vs rolled wheat) on rumen fermentation and performance during preparturient period. primiparous and multiparous cows were blocked by parity. the cows were fed diets as t...

Sixty-three Friesian heifers were assigned to three different diets (21 per group) of 11 MJ ME per kg DM containing low crude protein (CP, 142 g CP per kg DM) with high rumen protected protein (REP, 270 g REP per kg CP) (diet A), high-CP (183 g CP per kg DM) with low-REP (133 g REP per kg CP) (diet B) and high-CP (182 g CP per kg DM) with high-REP (267 g REP per kg CP) (diet C) to obtain livewe...
