An experiment was conducted to determine growth performance, carcass characteristics, and fat quality of growing-finishing pigs fed diets based on short-season corn hybrids. Twenty-four individually housed, Cotswold, growing pigs with an initial BW of 41.4 (SD = 1.4) kg were blocked by BW and sex and randomly allotted from within block to 1 of 3 diets to give 8 replicate pigs per diet. Experime...

We investigated continuous profiles and within-day variations of some metabolites and hormones in four nonpregnant, nonlactating cows fed hay-based diets in two equal meals. Diets supplied either too much or too little N (approximately 1.3 or .8 times the maintenance requirements) and NE1 (approximately 1.2 or .8 times). Continuous collection of ruminal liquor, blood, and urine samples was perf...

Introduction Sustainable growth of the salmon aquaculture industry is highly dependent on availability new feed resources as well improved management and utilization waste streams from production. Polychaetes are capable recapturing recycling valuable biomolecules contained in sludge at same time constitute a possible resource for aquafeeds. Material methods In this study, potential Hediste div...

Egyptian cheeses are considered an important part of the diet. This study aimed to examine 60 random samples different types commercial in Egypt, including soft (Domiati and Tallaga) hard (Cheddar Ras). The were subjected chemical microbial examination. Biogenic amines (BAs) nitrogenous compounds found a variety foods; their presence is undesirable related spoilage, can result toxicological eff...

one-hundred-sixty-eight 28-wk-old hy-line layers (w-36) were used to evaluate the effect of different levels of linseed (ls) and safflower seed (ss) on antibody titter, blood and yolk cholesterol, yolk fatty acid content and the ratio of omega-6/ omega-3. hens were randomly assaigned in a compeletly randomised design each 3 replicates of 8 hens. they were fed diets contained 0, 4, 7 and 10% ls ...

1. Endogenous levels of amino acids in ileal digesta were determined as the output from pigs given protein-free diets and by extrapolation to zero intake of linear regressions of ileal amino acid output v. dietary amino acid intake. The protein-free diets included 0 or 50 g cellulose/kg and extrapolations were made from two series of four diets which contained graded levels of wheat or barley a...

To know the conditions of contamination by the chemicals in the experimental animal diets, the contents of nitrosodimethylamine (NDMA) were analyzed in the diets for mice and rats. The raw materials of the diets were also analyzed. In addition, NDMA levels were determined in the diets which were stored long or heated in the autoclaves. The averages of NDMA in these diets were less than 10 ppb. ...
