Genetic effects on ewe productivity of crossing D'man and Sardi breeds of sheep.
Data from 364 ewes of Sardi (S), D'man (D), S x DS, DS x S, S x D, D x S (F1), F2, D x DS and DS x D breed groups mated to F1 rams were analyzed for fertility, number of lambs born alive, litter size at weaning, litter weight at weaning per ewe joined and mean lamb weight at 60 d. Each ewe was exposed in two seasons and had one or two lambings. Effects of breed group were significant for all tr...
متن کاملGenetic Analysis of Ewe Productivity Traits in Baluchi Sheep
The present study was carried out to estimate (co)variance components and genetic parameters for some productivity traits of Baluchi ewes. The data were collected during a 31 year period (1984-2014) at the experimental breeding station of Baluchi sheep, which is located in north-east of Mashhad, Iran. The analysis was based on 14030 records of lambs and 4371 records of ewes. Investigated traits...
متن کاملAssociation analysis of variant near ZNF389 with ewe cumulative production in three sheep breeds
experiments revealed the existence of eight and three single nucleotide polymorphisms (SNPs) at the promoter and 30-UTR of the goat LALBA gene respectively (Table S2 and Fig. S1). We also found eight additional putative polymorphic sites at exonic (all synonymous) and intronic regions. The potential functional significance of substitutions detected at the LALBA promoter was evaluated with the T...

Genetic Parameters of Direct and Maternal Effects for Growth Traits of Afshari Sheep
The genetic parameters and (co) variance components of body weight at birth (BW), weaning (WW) and six months of age (BW6) and average daily gain (ADG) pre and post-weaning of Afshari sheep were estimated using restricted maximum likelihood (REML) methodology and animal model implemented in DFREML software. The likelihood ratio test (LRT) was used to compare the models. Year of birth, age of mo...
