abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...

This study investigated the effects of different levels of prebiotic and peptide supplementations on growth performance, apparent digestibility of nutrients and fecal score in suckling Zell lambs. A completely randomized experiment was designed with a factorial arrangement of 3×2 containing 36 male suckling Zell lambs at the age of 10 days and with a mean weight of 4.4±0.33 kg for 70 days. The ...

Thirty six male Chall lambs (four-month old and 26  ±1.5 kg body weight) were randomly assigned into four treatments (nine lambs per treatment) to study the effect of Powerfeed® (a commercial mixture made from wheat processing by-product and wheat bran) on weight gain, feed intake, feed conversion ratio, serum sodium and potassium concentration and urine pH. Lambs in control group were fed with...
