Inbreeding 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...
متن کاملSingle Nucleotide Polymorphism Analysis of the Bone Morphogenetic Protein Receptor IB and Growth and Differentiation Factor 9 Genes in Rayini Goats (Capra hircus)
The FecB, a mutation in the bone morphogenetic protein receptor IB (BMPR-IB) gene, which increases the fecundity of Booroola Merino sheep, and FecGH, a mutation in the Growth and Differentiation Factor 9 (GDF9), which affects the fecundity of Cambridge and Belclare sheep in a dose sensitive manner, were analyzed as candidate genes associated with the prolificacy in Rayini goats. These polymorph...
متن کاملPhenotypic 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 Point Mutation in the Growth Differentiation Factor 9 Gene of Oocytes on the Sterility and Fertility of Awassi Sheep
Growth differentiation factor 9 (GDF9) plays a critical role in ovarian follicular development and ovulation rate. The present study aimed to investigate the correlation between the single-nucleotide polymorphism (SNP) of the GDF9 gene and reproductive performance variables, such as fertility and sterility in Awassi sheep. Forty pairs of ovaries from a total of 40 slaughtered Iraqi Awa...
متن کاملPre-weaning growth, carcass traits and sensory evaluation of Corriedale, Corriedale Pampinta and Pampinta lambs
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 ...
