Leptin, a 16-kDa protein secreted from white adipocytes, has been implicated in the
regulation of food intake, energy expenditure, and whole-body energy balance in rodents …

Simple Summary Understanding the physiological mechanisms responsible for the
reproductive and productive development of modern sow genotypes will help to create or …

The objective of this trial was to determine the effect of age at first estrus on BW changes and
long-term reproductive performance of sows. At approximately 100 d of age, prepubertal …

Puberty in gilts is the occurrence of first oestrus and the onset of reproductive capability
(usually at between 200 and 220 days of age). It is the combined effect of genetic factors and …

Reproductive records from 1072 Large White sows (3589 litters) were used to examine the
effect ofbackfat depth (Bd) and live weight (Lw) at selection on first litter and lifetime …

The objective of this study was to verify whether pubertal estrus could be influenced by the
growth rate and age of gilts at the onset of boar exposure. Gilts (n= 1486) were evaluated …

The timing of pubertal attainment in gilts is a critical factor for pork production and is an early
indicator of future reproductive potential. Puberty, defined as age at first standing estrus in …

Two hundred sixteen prepubertal Genex Manor hybrid F1 gilts were used to determine the
impact of lean growth rate on sexual development of gilts. This study was composed of two …

The primary goal of this qualitative case study was to investigate the nature of holistic
thinking in the context of an asynchronous computer conference. Holistic thinking was …

The objective of this study was to validate the use of exogenous gonadotropin (PG600)
treatment for stimulating estrus in noncyclic gilts and to compare lifetime productivity of gilts …
