The aim of the present study was to evaluate the influence of roasted soybean and sunflower meal on the consumption and growth performance of lambs from the Blackhead Pleven Breed. The results indicated that the addition of roasted soybean caused the lambs to grow significantly faster than those fed sunflower meal (P

in order to investigate the effect of processing type (whole straw bale processing or opened straw bale processing with urea) on diet digestibility, economical and productive parameters in feedlot cattle, 18 holstein bull with average body weight 224.72 ± 20.45 kg were used in a completely randomized design with 3 treatments and 6 replicate. treatments 1, 2 and 3 contained 40% typical straw, 40...

Fourteen trials were conducted to evaluate the effects of feeding monensin at 33 ppm alone, tylosin at 11 ppm alone and the two feed additives in combination on the average daily gain, average daily feed intake, feed:gain ratio and the incidence of liver abscesses in feedlot cattle. Monensin reduced feed intake and improved feed efficiency (P less than .05), and had no effect on average daily g...

association of genetic polymorphism in the calpastatin (cast) gene with average daily gain was examined in iranian purebred kurdi sheep. the genotypes for cast were determined by the pcr-sscp method. blood samples were collected from 84 purebred kurdi sheep belonging to the kurdi breeding station located in the khorasan province, north-east of iran. extraction of genomic dna was based on the gu...

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...
