Genetic correlations between gestation length, piglet survival and early growth
This study is based on 12708 first-parity and 7062 second-parity Yorkshire litters from Swedish nucleus herds; and on 1037 first-parity Yorkshire litters from an experimental herd. Gestation length was analysed together with litter size, piglet mortality and average piglet growth rate. A sire–dam model was used to estimate direct (litter) and maternal (sow) genetic effects. Direct heritability ...

Everyone responds to stressful status in their own way. Researches show anxiety and stress during pregnancy can have both immediate and long-term effects on her offspring. In addition, the emotional state of the pregnant m...
متن کاملHigh and Low Protein∶ Carbohydrate Dietary Ratios during Gestation Alter Maternal-Fetal Cortisol Regulation in Pigs
Imbalanced maternal nutrition during gestation can cause alterations of the hypothalamic-pituitary-adrenal (HPA) system in offspring. The present study investigated the effects of maternal low- and high-protein diets during gestation in pigs on the maternal-fetal HPA regulation and expression of the glucocorticoid receptor (GR), mineralocorticoid receptor (MR), 11β-hydroxysteroid dehydrogenase ...
متن کاملEffect of Oral and Intramuscular Administration of Ivermectin in Guinea Pigs on Survival of Blood-feeding Anopheles stephensi under Insectary Conditions
Background and purpose: Insecticide resistance in mosquitoes particularly malaia may lead to reemergence of malaria epidemics. This study aimed to investigate the effect of oral and intramuscular administration of ivermectin on guinea pigs exposed to Anopheles stephensi mosquitoes, the main malaria vector. Materials and methods: The effect of ivermectin was studied in oral and intramuscular ad...
