Genetic parameters for birth weight (BW), weaning weight (WW), 6 months weight (6MW), 9 months weight (9MW) and yearling weight (YW) in Baluchi sheep were estimated using data collected during a 26-year period (1984-2010). Estimates of (co)variance components were obtained by REML procedures by fitting a linear mixed animal model. Significant random effects for each trait were explored by fitti...

Two nuclear signalling pathways for vitamin D. Nature 1993;361: 657-60. (47) Elstner E, Linker-Israeli M, Umiel T, Le J, Grillier I, Said J, et al. Combination of a potent 20-epi-vitamin D3 analogue (KH 1060) with 9-cisretinoic acid irreversibly inhibits clonal growth, decreases bcl-2 expression, and induces apoptosis in HL-60 leukemic cells. Cancer Res 1996;56: 3570-6. (48) Elstner E, Linker-I...

to study the existence of clostridium septicum as probable agent associated with currently occurrence of black quarter in urmia area, sheep-dung samples were collected. the bacteriological examinations on suspicious gram positive anaerobic spore-bearing bacilli which are in clostridia genus include isolation and biochemical identification were performed. the results showed 28 different types of...

OBJECTIVES Lower birth weight (BW) reoccurs across generations, but the intermediate mechanisms remain poorly understood. One potential pathway involves cortisol, which may be elevated in women born small and in turn could lead to fetal growth restriction in offspring. To test this possibility, we evaluated whether BW predicts hypothalamic-pituitary-adrenal (HPA) function in the nonpregnant sta...

Genetic selection in primary broiler breeders may modify skeletal structure, possibly impeding semen transfer, and could alter the size and degree of fluctuating asymmetry (FA) of bilateral traits associated with fertility. Hence, we hypothesized specific morphometric traits could predict differential fertility. Sixty primary broiler breeder males from Strains A and B (n = 30/strain) were indiv...

Sheep in Australia experience periods with different feed supply causing them to gain and lose BW during the year. It is more efficient if ewes lose less BW during periods of poor nutrition and gain more BW during periods of good nutrition. We investigated whether BW loss during periods of poor nutrition and BW gain during periods of good nutrition are genetically different traits. We used BW m...

The current study investigated the effect of short-term selection for four week body weight (BW) on performance of divergent lines of Japanese quail and their crosses. The mean of BW at hatching time, one, two, three and four week oldand BW at sexual maturity time, age at sexual maturity, number of eggs (from 50 to 100 days old), mean of egg weight, percentage of fertility and hatchability in e...

Three experiments involving a total of 606 pigs weaned at 23 +/- 2 d of age were used to evaluate the effects of added dietary Na or Cl or both in combination (NaCl) on postweaning performance responses. A basal diet without added NaCl was formulated to 1.20% lysine using a corn-soybean protein mixture with 20% dried whey (C-SBP-DW) and was used in all experiments. The analyzed content of the b...
