UTERINE CAPACITY IN GILTS [PDF]

Reproduction, 1969
A review of the literature indicates that injection of gonadotrophic hormones or giving high-level-energy feeds will markedly increase the number of ovulations in polytocous animals. Higher ovulations rates are then followed by an increase in the precentage of embroys which die in utero.

Association of the AspP298Asn polymorphism in the MC4R gene with fattening productivity of immunologically castrated and uncastrated gilts

, 2023
The study was aimed at establishing the presence of MC4R (c.1426 A>G) gene polymorphism among the population of immunologically castrated and native gilts (Large White × Landrace) × Maxgro.

Influence of Backfat Thickness and the Interval from Altrenogest Withdrawal to Estrus on Reproductive Performance of Gilts

Animals, 2021
Estrus synchronization of gilts can be achieved by feeding the orally active progestogen altrenogest (AT) to cycling gilts at 20 mg/day for 14 to 18 days with gilts usually returning to estrus 4 to 8 days after the last feeding.

Personalities in female domesticated pigs: behavioural and physiological indications [PDF]

, 2000
The inconclusive evidence so far on the existence of distinct personality types in domesticated pigs, led us to perform the present experiment. A total of 128 gilts from 31 sows were systematically studied from birth to slaughter in two identical trials.

Comparison of Single, Fixed-Time Artificial Insemination in Gilts Using Two Different Protocols to Synchronize Ovulation

Animals, 2020
In order to efficiently have a consistent supply of service-ready gilts available to incorporate into each batch of breeding sows, it is necessary to manipulate the timing of estrus and possibly the timing of ovulation of gilts.

Effects of zearalenone on vulva area, liver function, serum immunoglobulin, antioxidant capability and sex hormone secretion of prepubertal gilts

Italian Journal of Animal Science, 2022
The study aimed to examine the multi-organs toxicity of zearalenone on prepubertal gilts. A total of 48 (Landrace × Yorkshire) prepubertal gilts were randomly divided into 4 groups with 12 replicates in each group.

COMPARISON OF INTRAMUSCULAR FAT CONTENT IN THE FIRST FARROWING GILTS AND IN THE FATTENING GILTS [PDF]

Journal of Central European Agriculture, 2010
The aim of the study was to compare the slaughter value and meat quality of the first farrowing gilts with normal fattening gilts. The study was carried out on 30 primiparous gilts (A) and 39 fattening gilts (B).

Zearalenone Altered the Serum Hormones, Morphologic and Apoptotic Measurements of Genital Organs in Post-weaning Gilts [PDF]

Asian-Australasian Journal of Animal Sciences, 2015
The present study was aimed at investigating the adverse effects of dietary zearalenone (ZEA) (1.1 to 3.2 mg/kg diet) on serum hormones, morphologic and apoptotic measurements of genital organs in post-weaning gilts.

Uterine size in replacement gilts associated with age, body weight, growth rate, and reproductive status

Czech Journal of Animal Science, 2014
The objective of the present study was to determine the association between the uterine size and age, body weight, growth rate, and reproductive status in Landrace × Yorkshire crossbred gilts. Genital organs from 310 gilts (302.6 ± 2.9 days of age, 145.2

CARCASS MARKET VALUE OF FATTENER GILTS AND PRIMIPAROUS GILTS [PDF]

, 2011
Study comprised 60 crossbred gilts F1 (PLW x PL), 30 fattener gilts (A) and 30 littermate primiparous gilts (B). The fattening was conducted in standard condition from 30 to 108 kg body weight. The primiparous gilts were mated at second oestrus.
