15 صفحه اولPhenotypic and Genetic Parameters of Pre-Weaning Growth Traits in Gentile di Puglia Lambs
Data from 1731 Gentile di Puglia lambs, sired by 65 rams over a 5-year period were analyzed by a mixed model to estimate the variance components for heritability. The considered growth traits were: birth weight (BW), weight at 30 days of age (W30) and average daily gain from birth to 30 days of age (DG). Year of birth, sex of lamb, type of birth (single or twin), dam age at lambing and farm wer...
متن کاملEffect of rearing system on pre-weaning growth, rumen development and its influence on post-weaning performance of lambs
Twenty-four 21-day-old Balouchi male lambs were equally divided into two groups. Twelve subjects were artificially reared (AR), twelve others were ewe reared (ER) and used as control. AR in comparison of ER lambs maintained higher concentrations of blood betaHydroxybutyric acid (BHBA); however glucose concentration was not affected by rearing system. Unlike the DNA content and cell size, the RN...

Birth weight (BW), weaning weight (WW), preweaning weight gain (PWG), carcass traits and sensory evaluation of meat of Corriedale (C), Pampinta (P) and their Fl crossbred (P C) lambs were studied from 1991 to 1993 at the Agricultural Experimental Station of Anguil (La Pampa, Argentina). Each year the trial involved an average of 35 C, 43 P and 36 P C. Data were analyzed for year, genotype, sex ...
متن کاملInbreeding effects on lamb pre-weaning growth traits and survival in three Iranian sheep breeds
The present study was performed to study the effect of inbreeding on the pre-weaning growth traits including the birth weight (BW), weaning weight (WW), average daily gain (ADG), Kleiber ratio (KR) and lamb survival from birth to weaning (SUR) in Baluchi, Iran-Black and Zandi sheep. Significant positive inbreeding trends were found only for Baluchi and Iran-Black breeds as 0.038 and 0.278, resp...
