the effect of silver nanoparticles as additive on broiler performance was investigated through employed of 312 day-old broiler chiks (arbor-acre plus) in a completely randomized design with 6 treatment diets each in 4 replicates. corn- soy based diets were formulated for starter, grower and finisher according to nrc (1994) recommendations. the silver nanoparticle solutions (2000 ppm) were added...

Objective: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks.  Methods: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks. Results: The results of experiment 1 indicated that there were no significant differences between earthw...

The influence of dietary Ca and P and growth rate from birth to 60 to 70 days of age on serum minerals, soundness scores and bone development was evaluated with crossbred gilts and barrows or boars. The following dietary treatments, as percentages of NRC recommendations for barrows and gilts, were used: (1) 100% Ca and P, (2) 125% Ca and P, (3) 100% Ca and 125% P and (4) 100% Ca and 75% P. Pigs...

Two growth studies were conducted to determine the Met and Lys requirements of growing cattle. In each 84-d trial, steer calves were fed individually diets containing 44% sorghum silage, 44% corn cobs, and 12% supplement (DM basis) at an equal percentage of BW. In Trial 1, 95 crossbred steers (251 kg) were supplemented with urea or meat and bone meal (MBM). Incremental amounts of rumen-protecte...

the present research was conducted to estimate the dietary lysine (lys) requirements of growing quails as based on performance and carcass constituents parameters at 3 to 24 d of age. the experiment was carried out in a complete randomized design arrangement the 6 dietary lys levels; 1, 1.15, 1.30 (nrc 1994), 1.45, 1.60, and 1.75 %, from 3 to 24 d of age. a dose-response diet mainly based on co...

A 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of Ancherythroculter nigrocauda (mean initial body weight, 23.30±0.59 g). Seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 KJ g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[c...
