The Meishan pig provides a biological model with the genetic capacity to express a high prolificacy. This prolificacy can be partially attributed to a higher ovulation rate and a higher rate of prenatal survival at a given ovulation rate throughout g

In the southern United States, corn production encounters moisture deficit coupled with high-temperature stress, particularly during the reproductive stage of the plant. In evaluating plants for environmental stress tolerance, it is important to moni

Data on lamb survival from birth to weaning of Rambouillet and Finnsheep were analysed with sire-maternal grandsire linear (LM) and threshold (TM) models. Models for the Rambouillet included the effects of year, type of birth, age of dam and sex as f

Gilts were the progeny of eight Duroc, nine Meishan, eight Fengjing, and seven Minzhu boars mated to composite (1/4 Chester White, 1/4 Landrace, 1/4 Large White, and 1/4 Yorkshire) females. Age at puberty was youngest (P < .05) for Meishan and Fengji

Three generations of selection for 56-d blood cholesterol concentrations were used to establish low and high cholesterol lines of pigs in which cholesterol concentrations differed by 39% in the last generation. Litter size (number of fully formed pig
