this study was carried out to determine the effects of different levels of protein and probiotic (protexin) on performance, and immune response in ross (308) broiler exposed to heat stress. five hundred and forty one-day old broilers were employed in a compeletly randomized design (3×3 factorial arrangement) of 3 replicates for each treatment. the diets were formulated according to nrc (1994) r...

prosite database contains a set of entries corresponding to protein families, which are used to identify the family of a protein from its sequence. although patterns and profiles are developed to be very selective, each may have false positive or negative hits. considering false positives as items that reduce the selectiveness of a pattern, then, the more selective pattern we have, a more accur...

A completely randomized design, with 3×3 factorial arrangement, was conducted to test various ratios of dietary protein to energy (P/E) for rainbow trout, reared in brackish water. Three crude protein levels (35, 40 and 45%) and three energy levels (370, 400 and 430 Kcal/100g) at each protein level were utilized. Semi-purified diet containing fish meal, casein and gelatin as the sources o...

nine multiparous lactating cows averaging 171 days in milk were divided according to days in milk and milk production into three 3×3 latin squares with three 3-week periods to investigate the effect of rumen degradable protein on milk urea nitrogen. diets were formulated to provide 3 concentrations of dietary rumen degradable protein (9.8, 10.8, and 11.8% of dry matter), while rumen undegradabl...
