digestibility coefficient of whole cottonseed was determined by in vivo method and total collection feces. the whole cottonseed degradability was determined by nylon bag method. a number of 12 holstein bulls were used in a complete randomized design. the rations contained zero (control), seven, 14 and 21 percentages of whole cottonseed. during the experimental period, daily gain, dry matter int...

Black soldier fly larvae (BSFL) are highly efficient at converting organic substrates into insect biomass suitable for livestock nutrition. BSFL conversion efficiency depends on the nature of their feed, and formulation approaches use macronutrient contents to reach a targeted performance. However, digestibility varies between ingredients data is lacking due methods unsuitable insects living in...

This study was conducted to investigate the effect of decreasing concentrations dietary neutral detergent fiber (NDF) at high rumen undegradable protein (RUP) on performance, digestibility, chewing activity, blood attributes, and carcass characteristics in 32 weaned male Afshari lambs (90 days age; 26 kg initial body weight; BW). Dietary metabolic energy (ME) increased from 10.6–11.5 11.8 MJ/kg...

this study was carried out to investigate the effects of medicinal plants, prebiotic and probiotic as alternatives to antibiotics on the growth performance, intestinal morphology and ileal digestibility of nutrients in broilers. a total of 288 one- day-old broiler chicks (cobb 500) were randomly assigned to 6 treatments and 4 replicates with 12 chicks per each replicate in a completely randomiz...

the aim of this study was to investigate the effect of commercial herbal and chemical medicines on growth performance, serum lipids, intestinal selected bacterial population and intestinal morphology of broiler chickens. in this study, 450 day-old female broiler chickens (arian strain) were divided into 10 treatments with three replicates of 15 chicks per replicate. on day 14 of the experiment,...

The experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. Twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...

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 investigate the effects of two levels of metabolism energy (me) and length of fattening periods on performance and growth characteristics of chalishtori male lambs. 64 ram lambs were weaning and intake diets with two levels of energy include: 2.5 and 2.3 mcal me/kg dm in 90 and 120 days fattening period. in this study used of completely random designs with 2×2 factorial methods (...
