abstract this study aimed to investigate the effects of different levels of the amino acid lysine on growth performance, feed efficiency and body composition of juvenile snow trout (schizothorax zarudnyi). for this purpose, 150 fish with average weight 22.51±0.28 g fed with five levels of dietary amino acid lysine including 0 (control), 7, 12, 17 and 22 g/kg diet, for 8 weeks. fish fed two time...

This study was conducted with different levels (0, 0.25, 0.5,1,2 g) of Zingiber officinale powder per 100 g of common carp commercial diet. Feed was offered for 8 weeks by the post pelleting liquid spraying method. Results showed that there were significant differences in all growth parameters and body composition except in survival rate, Gain Weight Percent (GW%) ,SGR and NFE between treatment...

The weighing records of 18 crossbred females with average live weight of 14.7 ± 3.14 kg were analyzed to study the relationship of the growth of crossbred hair sheep with some zoometric measures. The weight was established and took the measures thoracic perimeter, cannon perimeter, body length, neck length, hip amplitude, ischial amplitude, withers height and croup height. All parameters were s...

This study was conducted to evaluate the effects of the different levels of vermi (Eisenia fetida) meal on fermented ration in broiler chicken growth and profitability under two management systems. For this purpose, 120 day old broiler chickens (cobb vantress) were tested in a Completely Randomized Design with four (4) dietary treatments: first, the commercial feeds (control), second, 2% vermi ...

the present study evaluated effects of 0.0%, 0.5%, 0.75% and 1.0% l-threonine in diet on performance and gastrointestinal tract development in broiler chickens during summer. from 0 to 42 days old, body weight gain was greater in 0.75% l-threonine fed birds than in 0.0% and 0.5% l-threonine fed birds (p0.05). during the growth period, 0.75% l-threonine fed birds had the highest body weight gain...

Objective: Nowadays the value of bioelectrical impedance analysis (BIA) in the estimation of body adiposity both on a clinical basis in the individual and epidemiologically in large populations is of great interest. The current study determine accuracy of BIA compared with body mass index (BMI) measurement for estimating body composition in a group of normal weight employee women with a sedenta...
