The objective of this research was to estimate genetic correlations between number of piglets born alive in the first parity (NBA1), litter birth weight in the first parity (LTBW1), number of piglets ...
The Society for Reproduction and Development (SRD) was established in 1948 to encourage the study of reproductive biology in wild, domestic, laboratory, and companion animals. This was two years befor...
The European Society for Domestic Animal Reproduction-ESDAR is a non-profitable community with special emphasis on reproduction in domestic animals and wild animals as well. The society supports all a...
Propagation of pikeperch Sander lucioperca by semi-artificial management was investigated using hormonal induction to better understand the effect of hormonal treatment of both sexes. Fourteen pairs o...
The objective of the current pilot study was to evaluate the reproductive performance and health indicators in Dorper, White Dorper, and Tsigai breed ewes managed semi-intensively under European tempe...
The objective of this study was to evaluate the relationships between several health disorders: milk fever (MF; hypocalcaemia and parturient paresis), retained placenta (RP; retained foetal membranes)...
The study presents estimates of heritability for fur coat and reproduction traits in arctic and silver foxes kept on Polish farms. The estimates of variance components were calculated using the DFREML...
Selenium plays an important role in boar nutrition via participating in selenoprotein synthesis. It seems likely that selenoproteins are central for antioxidant system regulation in the body. Se-depen...
Genetic parameters of production and reproduction traits were estimated using 39,926 records from 5,860 individual progenies of 163 sires and 1,558 dams. The data were collected at Makuie Sheep Breedi...
One of the main goals of small, medium and large farms is to improve the reproductive performance of rabbit does. Stocks of lower productivity can be improved by crossing with intensive breeds. A bett...
Appropriate timing of various seasonal processes is crucial to the survival and reproductive success of animals inhabiting temperate regions. When seasonally breeding animals are subjected to annual c...
Many seasonal breeding animals can estimate the day length (photoperiod) and prepare for breeding in the optimal season. The Japanese quail (Coturnix japonica) is an excellent model for studying photo...
The reproduction component traits are important components of sow efficiency. The objective of this study was to evaluate the phenotypic and genetic parameters of four reproduction component traits (a...
The effects of utilizing evaporative cooling system equipped with tunnel ventilation on postpartum ovarian activities, energy balance and milk production of early lactating dairy cows under hot and hu...
The correlations between longevity, functional longevity, stayability and selected milk, reproductive and type traits were estimated; it was done on the basis of estimated breeding values for longevit...
