Correlation between estrus onset and ovarian parameters in dairy goats. Abstract: This study assessed the effects of social dominance on the behavioral estrus and ovarian parameters of dairy goats subjected to synchronous estrus induction during the non-breeding season. S... ... Repositório: BDPA Ano de publicação: 2022
Induction of synchronized estrus in dairy goats with different gonadotrophins. The objective of this study was to evaluate lhe efficiency of two gonadotrophins in induction of estrus in dairy goats. A total of 47 dairy goats were randomly divided according to breed into two trea... ... Repositório: BDPA Ano de publicação: 2005
Does GnRH treatment at TAI regardless of estrus occurrence increase pregnancy rate in crossbred Bos taurus suckled cows? The impact of GnRH treatment on the day of TAI in beef cows has received limited investigation, especially concerning its association with estrus expression. Consequently, two experiments were conduct... ... Repositório: BDPA Ano de publicação: 2024
Effects of hCG administered 7.5 days after synchronous estrus induction during the non-breading season in Morada Nova ewes. This study was designed to assess the effects of human chorionic gonadotropin (hCG) administration 7.5 days after the end of synchronous estrus induction protocol in Morada Nova ewes in the non?breedi... ...

Increasing 12 h of intravaginal device permanence allows greater estrus synchrony but lower pregnancy rates in artificially inseminated acyclic dairy goats. This study assessed in dairy goats the effect of hormonal induction treatments varying only 12 h in progestogen device permanence on estrus synchrony and fertility. In both Experiments, goats received... ... Repositório: BDPA Ano de publicação: 2020
