Comparative evaluation of estrus synchronization protocols on reproductive performance and estrus behavior in Barbados Black Belly sheep

This study aimed to compare the effectiveness of three treatment protocols and to record the intensity and duration of estrus signs and pregnancy rate in Barbados Black Belly (BBB) sheep.

The reversible effects of gossypol toxicity on male pigeons' reproductive performance

In this study, the antifertility potential of gossypol in pigeons was evaluated for the first time to determine whether it might be used as a dietary supplement for pigeon population control

The Barb horse occupies a prominent place in the history, culture, and equestrian traditions of the Maghreb (Algeria, Morocco, and Tunisia).

Differential effects of foot-and-mouth disease infection and vaccination on fertility of Holstein–Friesian heifers: Evidence from a within-animal retrospective study in Indonesia

This study evaluated the association of clinical FMD infection and inactivated FMD vaccination with reproductive performance in Holstein–Friesian heifers using a within-animal retrospective design.

Field evaluation of sexed and conventional semen in Holstein–Friesian cows: Linking semen quality with fertility and calf sex ratio across climatic zones

This study evaluated laboratory semen quality and field reproductive performance of sexed and conventional semen in Holstein–Friesian cows across different climatic zones.

Augmented-OvSynch enhances estrus resumption, luteal function, and conception rates in postpartum Zebu crossbred cows under tropical smallholder systems

This study evaluated the effectiveness of an Augmented-OvSynch protocol incorporating a post-insemination gonadotropin-releasing hormone (GnRH) injection in improving reproductive performance and assessing associated endocrine and oxidative stress dynamics in…

Effects of fermented potato protein supplementation on serum insulin-like growth factor-1 (IGF-1) concentrations, skeletal muscle IGF-1 mRNA expression, and the interval to first postpartum estrus in tropical crossbred dairy cows

This study aimed to evaluate the effects of FPP supplementation on serum IGF-1 concentrations, skeletal muscle IGF-1 mRNA expression, and the interval from calving to first postpartum estrus.

Determinants of prolonged weaning-to-service interval in primiparous Landrace × Yorkshire sows under tropical conditions: Impact of age at first farrowing, lactation length, and litter size at weaning

This study aimed to identify critical risk factors associated with prolonged WSI (>6 days) in first-parity Landrace × Yorkshire sows raised under tropical conditions.

Impacts of early postpartum behavioral patterns on the fertility and milk production of tropical dairy cows

This study aimed to investigate how these behavioral patterns, as captured by smart biosensor data, influence reproductive outcomes, and milk yield in Holstein Friesian cows, with specific emphasis on parity differences and behavioral clustering.
