This study examined the effect of supplementing exogenous cellulase on nutrient and energy utilization. Twelve desexed Boer crossbred goats were used in a replicated 3×3 Latin square design with 23-d periods. Dietary treatments were basal diet (control, no cellulase), basal diet plus 2 g unitary cellulase/kg of total mixed ration dry matter (DM), and basal diet plus 2 g compound cellulase/kg of...

the effect of crossbreeding between ghezel and mehraban on growth performance and carcass characteristics was studied for two consecutive years using 162 purebred and crossbred lambs. the four groups of lambs involved in the study were purebred mehraban (mm), purebred ghezel (gg), crossbred ghezel ram×mehraban ewe (gm) and crossbred mehraban ram×ghezel ewe (mg). the lambs were fed with grazing ...

Abstract The objective of this study was to evaluate the carcass traits crossbred F1 goats (Boer x non-descript breed) finished on thinned caatinga pasture enriched with signal grass (Urochloa trichopus Stapf.), and receiving supplementation. Twenty-four 27.00 ± 3.32 kg body weight were used. supplement designed meet nutritional requirements animals highest supplementation level could gain 150g...

The objective of this study was to evaluate the growth and efficiency-related traits Boer x Central Highland goats. Besides, genetic non-genetic factors affecting (Kleiber ratios) were identified. Data collected for nine years a general linear model procedure SAS employed detect significance fixed effects. overall least-squares mean live weight at birth, 3-, 6-, 9- 12 months age 2.52±0.01, 9.81...

Crossbreding is predominant and intensively used in commercial meat production systems, especially in poultry and swine. Genomic evaluation has been successfully applied for breeding within purebreds but also offers opportunities of selecting purebreds for crossbred performance by combining information from purebreds with information from crossbreds. However, it generally requires that all rele...
