Soybean isoflavone reduces the residue of zearalenone in the muscle and liver of prepubertal gilts.
The aim of the present study was to evaluate the protective effects of isoflavone (ISO) against zearalenone (ZEA) residues in the muscle and liver tissues of prepubertal gilts. Seventy 75-day-old, prepubertal, female pigs (Duroc × Landrace × Yorkshire, 26.5 ± 0.60 kg) were allocated randomly to seven diet treatments for 21days as follows: one control group (fed the basal diet) and six groups fe...
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 کاملPrepubertal exposure to dietary zearalenone alters hypothalamo-hypophysial function but does not impair postpubertal reproductive function of gilts.
At an average age of 70 d, 60 Yorkshire gilts born either in July (Trial 1; n = 30) or August (Trial 2; n = 30) received a diet containing zearalenone for 0 (control), 45 or 90 d. The concentration of zearalenone in diets was 2 ppm for 2 wk and 1.5 ppm for the remainder of the study. Vulval swelling and reddening was evident within 7 d after zearalenone was first fed. Zearalenone consumption ha...
متن کاملLow concentrations of zearalenone in diets of mature gilts.
Four groups of sixteen gilts were each individually fed diets containing 0, 3, 6 or 9 ppm pure zearalenone starting the day after they exhibited puberal estrus. They were artificially inseminated twice at subsequent heat periods. Fifteen of the 30 gilts not exhibiting estrus within 80 d of the start of the experiment were slaughtered and their reproductive tracts examined. The remaining 15 gilt...
متن کاملEffect 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); ...
