Effect of prepubertal feeding regimen on reproductive development of gilts.
The effect of prepubertal feed level on growth and reproductive development of gilts was investigated. At 13 wk. of age, white crossbred gilts were penned individually and assigned to the following treatments: Ad lib, ad libitum intake from 13 to 25 wk. of age (n = 64); Control, ad libitum intake from 13 wk. of age until 100 kg BW and then 90% of ad libitum intake until 25 wk. of age (n = 65); ...
متن کاملReproductive Hormone and Transcriptomic Responses of Pituitary Tissue in Anestrus Gilts Induced by Nutrient Restriction
The onset of estrus is a critical sign of female sexual maturity. The pituitary plays a vital role in this process by the secretion of reproductive hormones. To investigate the effects of nutrient restriction on reproductive function and the underlying mechanisms involved, deep RNA sequencing of pituitary gland tissue was carried out to determine the differentially expressed genes (DEGs) betwee...
متن کاملEffect of prepubertal feeding regimen on reproductive development and performance of gilts through the first pregnancy.
Development of gilts that conceive early and continue to produce offspring is an objective of swine production. We investigated different patterns of growth on reproductive development and performance of gilts through the first farrowing. At 13 wk of age and 43 kg BW, 286 white crossbred gilts were penned individually and assigned to treatments: Ad lib, ad libitum intake from 13 to 25 wk of age...
متن کاملUterine response to progesterone in prepubertal gilts.
During early pregnancy, progesterone stimulates the secretion of proteins and other molecules that support the developing conceptus. Some gilts are able to support conceptus development as early as 110 days of age. The objective of this study was to evaluate the onset of responsiveness of the prepubertal uterus to progesterone. Thirty gilts were assigned to receive 2.2 mg progesterone kg-1 body...
متن کاملLevel of dietary energy during prepubertal growth and reproductive development of gilts.
Development of gilts that conceive early and continue to produce offspring is a primary objective of swine production. The objective of this study was to determine the degree of feed restriction during development required to optimize reproductive performance and efficiency in gilts. The effects that various patterns of growth had on reproductive development and performance of gilts through d 3...
