Data on 5,130 unsupplemented Hereford range cattle were used to evaluate genetic and phenotypic parameters of growth to 2 yr of age under extensive range conditions. From those data, records on 769 heifers saved as replacements were used to evaluate the relationship between growth and subsequent productivity expressed as most probable producing ability (MPPA). Variation in weight largely was du...

in this study, genetic parameters and (co)variance components were estimated for weights at birth, 3, 6, 9, 12, 24 months, daily weight gain from birth to 3 months and daily weight gain from 3 month to 12 month, keliber ratio from birth to 3 months and keliber ratio from 3 to 12 month, and production of fleece for south khorasan goats at sarbisheh station over a period of 16 years (1996–2012). ...

this study was carried out to evaluate the effects of different dietary protein (30, 35, 40%) and lipid levels (10, 12, 14%) on growth performance and physiological changes of juveniles caspian kutum (rutilus frisii kutum). six hundred and seventy five fish (1.15 ± 0.01 g) were distributed into 27 aquaria (45 l) and were fed four times daily for 8 weeks. interaction between protein and lipid di...

abstract in order to investigation the effect of different levels of onion powdr (allium cepa) on growth performance, survival, fillet composition and hematological parameters of  rainbow trout, a completly randomize design with six treatments and three replicates (15 fish in each replicate) were conducted for eight weeks. experimental dietary included 0, 0.5, 1, 2, 3 and 5% onion powder. all t...

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...

purpose weight loss in wrestling has been found to be an interesting issue for researchers. in this regard, complications of weight loss in wrestlers before the competitions and their weight gain in course of competitions have been debated in previous studies. the objective of this study was to investigate the extent of weight gain and to estimate the percentage of body fat in participants in t...

this study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (psp) on performance and blood parameters in laying hens. a total of 96 layers hens (hy-line w-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of psp, with 4 replicates containing 6 layers in each. results showed no significant effec...
