Effect of Crossbreeding European Sheep Breeds with Awassi Sheep on Growth Efficiency of Lambs in Jordan

Original language description

The objective of this study was to evaluate the effect of crossbreeding on body weight and growth efficiency of lambs from birth to weaning. The study was conducted on the Awassi sheep flock and their crossbreds with Charollais and Romanov breeds maintained at the Agriculture Centre for Research and Production at JUST Irbid. In 2004, 2005 and 2006 live weight was determined in 420 lambs (95 Awassi, 158 Charollais x Awassi F1 crossbred and 167 Romanov x Awassi F1 crossbred) at birth and subsequently every fortnight until weaning. Average live weights of lambs at birth,15, 30, 45 and 60 days of age were 4.18 &#61617; 1.13 kg, 8.85 &#61617; 2.12 kg, 12.20 &#61617; 2.80 kg, 15.70 &#61617; 3.50 kg and 19.25 &#61617; 4.60 kg, respectively. ADG of lambs frombirth until weaning was 255 ? 0.10 g. Genotype of lambs and litter size affected ADG, live weight of lambs at birth, 15, 30, 45 and 60 days significantly (P &#8804; 0.001). Investigations of the effect of sex on live weight of lambs at bi
