Estimation of genetic parameters and inbreeding depression in Piau pig breed

Tropical Animal Health and Production, 2022
This study is aimed at estimating genetic parameters, effective population size, inbreeding, and inbreeding depression for birth weight, weaning weight, and average pre-weaning daily weight gain (ADG) in Piau pigs. We used information from 3841 Piau pigs, and four linear models were fitted in single-trait analyses, including or excluding maternal ...

Effects of heat stress on performance and thermoregulatory responses of Piau purebred growing pigs

Journal of Thermal Biology, 2021
The study of how different breeds adapt to heat stress and the further understanding of mechanisms underlying pigs thermotolerance is of utmost importance to attenuate the negative effects of heat stress on pigs welfare, physiology, and performance.

Sexual behavior and seminal quality of Piau boars

Journal of Veterinary Behavior, 2013
Abstract The objective of this study was to assess parameters of sexual behavior, seminal characteristics, testicular measurements, and their correlations in Piau boars. A total of 169 observations of the sexual behavior and prelude duration (courting) of 10 Piau boars aged from 0.8 to 6.4 years were made; semen was also collected from these animals ...

Duration of spermatogenesis and sperm transit time through the epididymis in the Piau boar

Tissue and Cell, 1998
The Piau boar is a rustic breed of economical importance in Brazil. The duration of spermatogenesis and sperm transit through the epididymis in Piau boars was estimated using intratesticular injections of tritiated thymidine. Animals were sacrificed 1 h, 7 days, 14 days, 21 days, 34 days, and 36 days after injections.

Cryopreservation of Piau‐Breed Wild Boar Sperm: Assessment of Cooling Curves and Centrifugation Regimes

Reproduction in Domestic Animals, 2015
ContentsThis study aimed to assess the effects of different cooling curves and centrifugation regimes used in cryopreservation protocols on the post‐thaw viability of Piau‐breed wild boar (Sus scrofa) sperm using in vitro assessment tests. Two centrifugations (800 g for 10 min and 2400 g for 3 min) and two cooling curves (conventional cooling using ...

Effect of different cryo-protectants on the viability of frozen/thawed semen from boars of the Piau breed

Animal Reproduction Science, 2014
The objective of this study was to evaluate the effect of different cryo-protectants (glycerol, dimethylacetamide and dimethylformamide alone or combined and added to lactose-egg yolk extender) on the viability of frozen/thawed semen from the Piau breed as assessed by in vitro testing. Frozen semen samples (n=20) were used from five male swine.

Transcriptional profile of Piau breed conceptuses and morphohistological characteristics of the uterus of pregnant Piau sows

During gestation, the uterus undergoes essential morphofunctional adaptations to ensure embryonic viability, providing an adequate environment for early conceptus development. Placental functional efficiency is a key determinant of fetal growth and survival, particularly in the early stages of pregnancy, and breed differences may be reflected in ...
