ABSTRACT This study aimed to investigate the roles of miRNA in the development of ovarian follicles in sows with high ovulation rate. The miRNA expression profiles in middle-size ovarian follicles between Meishan and Duroc sows were characterized by Affymetrix miRNA GeneChip. Seven differentially expressed miRNA were identified. KEGG pathways analyzed the predicted target genes of differentially expressed miRNA by using the DAVID website. The MAPK signaling pathway may affect the process of ovarian follicle development. Our study suggested that miR-21, […]

ABSTRACT The present study evaluated the optimal duration of creep feeding that improves the growth performance and fecal score of piglets and the performance and estrus interval of sows. Sixteen sows (Yorkshire × Landrace) and their litters were used in this 24-day trial. Dietary treatments were: Treatment 1, in which creep feed was not provided; treatment 2, in which creep feed was provided at the 7th day of life (day 7 to weaning); treatment 3, in which creep feed was […]

A total of 335 records of swine litters from 102 Large White females that farrowed between 1985 and 1996, born in the seasons of september to february and march to august, in the Recife city, in Pernambuco state (Brazil), were analysed. The objective was to compare regression equations to predict stillborn rates. Angular transformation (TA), a generalized linear model (GLM) with binomial distribution and logit link (BL), a Poisson GLM with log link (PL), a mixed GLM (GLMM) with binomial […]
