The suitability of fermented pigeon pea meal as a protein ingredient in diets for Clarias gariepinus fingerlings was evaluated. A strain of Rhizopus oligoporus was used to ferment the meal for six days at 37°C. Five isonitrogenous (30% crude protein) and isoenergetic (16.45 MJ/kg) diets were formulated in which fermented meal was used to replace soybean meal at five inclusion levels (0%, 25%, 5...

The response of laying Japanese quails to dietary levels of energy and protein on performance, egg quality, hatchability, fertility and their effect on subsequent offspring live body weight was investigated. A total of 432 Japanese quails (13 weeks old) were divided into nine treatments. Each treatment comprised of four replicates of twelve birds (9 females and 3 males). Nine diets including th...

for this reason the samples were obtained from three area in kerman province that cartivate corn in large amounts (giroft, kahnooj, baft).the amounts of samples were enough for both voluntary consumption and investigation of digestibility. after that samples had been chopped by electric chopper we sampled again from every sample and its chemical compositions were determined with standard method...

Five trials involving 432 growing boars were utilized to study the effects of six levels of crude protein on gain, feed efficiency, feed intake, backfat thickness and longissimus muscle area. The boars were fed ad libitum either a 14, 16, 18, 20, 22 or 24% crude protein diet from about 24.6 to 54.4 kg (period 1). From 54.4 to 98.8 kg (period 2), the crude protein in each diet was reduced by 2%....

The aim of this study was to examine the effect age and dietary crude protein (CP) level on nitrogen (N) excretion in dairy heifers develop simple models predict N farm based nutrient intake parameters. Thirty-six Danish Holstein were divided into 4 groups; 8, 12, 16, 20 months old (M8, M12, M16, M20), respectively, with 9 animals per group. Heifers within groups blocked 3 according pregnancy s...

in this study, the chemical composition of the tea wastes determined. the value of dry matter, organic matter, crude protein, crude fiber, calcium and phosphorous 95, 94, 13.3, 23.1, 0.011 and 0.29 percent, respectively. in the experiment of digestibility by animal, five experimental rations (including tea waste and alfalfa in the proportion of 0:100, 10:90, 20:80, 25:75 and 30:70 percent) and ...
