Effects of ewe live weight and age on reproductive performance, lamb growth, and survival in Central Anatolian Merino sheep
The aim of this study was to evaluate the effects of premating ewe weight and age on ewe reproductive performance, lamb growth and survival in Central Anatolian Merino (CAM) sheep. The trial included 4935 ewes and 5548 lambs from 23 breeder flocks in Eskişehir Province. The live weights (LWs) and ages of the ewes were recorded 1 week before the mating season.

متن کاملNational sheep improvement program: age adjustment of weaning weight.
Lamb weaning weights at 30 +/- 14, 60 +/- 28, and 90 +/- 28 d were used to evaluate the effect of birth weight on the linear adjustment of weaning weight to a constant age and the effect of deviations from target dates on the accuracy of linear age adjustment. The data consisted of 13,501 birth weights, 3,721 30-d records, 10,988 60-d records, and 3,285 90-d records from the National Sheep Impr...
متن کاملThe influence of live weight, live-weight change and diet on protein synthesis in the skin and skeletal muscle in young Merino sheep.
