Genetic parameters for a subjective milk score given to ewes within 24 h of parturition were estimated to determine the usefulness of milk score as a selection trait to improve milk production, which influences total litter weight weaned. Heritability of milk score and the genetic correlation of milk score with litter weight weaned were estimated by REML separately for four sheep breeds, Rambou...

A Hamiltonian approach to black hole entropy is used study Riemannian Kerr-AdS solutions in the general, parity-violating Poincaré gauge theory. Asymptotic charges and are entirely determined by parity-even sector of theory, since related parity-odd contributions vanish. The resulting thermodynamic variables shown satisfy first law thermodynamics.

The effects of frame size (FS) and body condition score (BCS) on performance of Brahman cows were evaluated using records collected from 1984 to 1994 at the Subtropical Agricultural Research Station, Brooksville, Florida. Age at puberty (AP), calving rate (CR), calving date (CD), survival rate (SR), weaning rate (WR), birth weight (BWT), weaning weight (WWT), preweaning ADG, and kilograms of ca...

Estimates of heritabilities and genetic correlations for calving ease over parities were obtained for the Italian Piedmontese population using animal models. Field data were calving records of 50,721 first- and 44,148 second-parity females and 142,869 records of 38,213 cows of second or later parity. Calving ability was scored in five categories and analyzed using either a univariate or a bivar...

BACKGROUND AND PURPOSE Subarachnoid hemorrhage (SAH) is the only type of stroke with female predominance, suggesting that reproductive factors may play a role in the etiology. We conducted a population-based study to examine the influence of parity on the risk of SAH in women. METHODS We linked data from 3 national Swedish registries to identify first-ever hospitalizations for SAH in a cohort...

osteoporosis is considered as an important public health problem especially in postmenopausal women. there are some hypotheses support the contributory effect of pregnancy and lactation on osteoporosis later in life. high calcium demand during pregnancy and lactation and low estrogenic state support those hypotheses. numerous studies have investigated on the issue but there is no consensus abou...
