Discriminant analysis of post-thaw sperm cryotolerance among three chicken breeds in a hot, humid tropical environment
Sperm cryopreservation is a practical reproductive technique, with variations in post-thaw sperm quality observed among different breeds. Discriminant functions can be used to distinguish breed-specific responses to cryotolerance. This study applied multivariate discriminant analysis to evaluate…

Protective effects of ascorbic acid against fluoroquinolone-induced spermatogenic disruption in wistar rats
Ciprofloxacin, a widely used fluoroquinolone for the treatment of bacterial infections, has been associated with adverse effects on male reproductive function. This study investigated the protective effects of ascorbic acid on semen quality and testicular histomorphology in male Wistar rats treated…

Parity-related changes in serum biochemical profile, estrus response, and conception rate following double PGF2α estrus synchronization in Ettawa grade dairy goats
Parity affects metabolic status and reproductive performance in female livestock. Since metabolic status can influence ovarian function and fertility, assessing serum biochemical profiles during estrus synchronization may help predict reproductive performance. This study assessed parity-related…

Histological structure of rat preantral follicles after vitrification using date juice as a natural extracellular cryoprotectant
Cold shock, cryoinjury, and apoptosis remain major challenges in ovarian vitrification because they compromise the structural integrity of follicular cells. Date juice (DJ), which contains natural sugars and antioxidant compounds, may provide cryoprotective effects during vitrification. This study…

Influence of clinically differentiated estrus vaginal pH windows on offspring sex ratio following artificial insemination in west African dwarf goats
The offspring sex ratio in mammals is generally considered to occur by chance, with many reports indicating an approximately 1:1 (male:female) ratio. The ability to influence this natural biological ratio could provide significant socioeconomic benefits in livestock production. Although sex-sorted…

Phenotypic stability of reproductive traits in dorper sheep under intensive tropical production systems
This study evaluated the reproductive performance of Dorper sheep in an intensive system in West Java, Indonesia. Data included ewe parity (P1 and P2), lambing interval (LI), litter size at birth (LSB), weaning litter size (WLS), age at first lambing (AFL), annual reproductive rate (ARR), and…

An experimental evaluation of cucumber (cucumis sativus) juice-fortified extenders: effects on semen motility, viability, and microbial dynamics in clarias gariepinus
Conventional semen extenders are often inaccessible to smallholder aquaculture because of their high costs and infrastructure requirements, while bacterio-spermia and oxidative damage further compromise sperm quality during storage This study evaluated a cucumber juice-based semen extender…

Effects of storage time on chilled sperm characteristics of three exotic boars reared under Cameroonian production conditions
The semen quality of exotic boar breeds introduced into Cameroon has been poorly assessed, and the characteristics of their chilled spermatozoa remain largely unknown. In artificial insemination (AI) programs, regular monitoring of semen quality is essential to maintain high reproductive…

Socioeconomic and management factors associated with recognition of infertility signs and reproductive performance in smallholder dairy cattle farming in Tanzania
Understanding the factors that influence dairy farmers’ awareness of infertility and reproductive performance is critical for improving productivity. This cross-sectional survey sampled farmers across six Tanzanian regions (Njombe, Mbeya, Tanga, Kilimanjaro, Arusha, and Morogoro) and used…

Dietary vitamin C supplementation improves semen quality and antioxidant activity in Japanese quail under summer heat stress
Heat stress severely affects the redox balance of poultry semen, as the limited supply of natural antioxidants is unable to neutralize the excessive production of free radicals. This oxidative stress can reduce sperm quality and reproductive productivity in Japanese quails during summer. Dietary…

Anti-androgenic and antifertility activity of Azadirachta indica seed oil in male albino rats
Two experimental phases (I and II) were conducted to investigate the reproductive effects of Azadirachta indica methanol seed extract (AIMSE) in adult male albino rats. In Phase I, male rats were randomly assigned (fourteen per group) to four groups: a control group (A) and three groups treated…

Effect of green tea (Camellia sinensis L.) extract on the quality of Gaok rooster spermatozoa stored in a fructose-egg yolk-milk diluent at room temperature
This study evaluated the effect of a fructose-egg yolk-milk diluent supplemented with different concentration of green tea leaf extract (Camellia sinensis L.) on the quality of rooster semen stored at room temperature (25 °C). Semen was collected from five healthy Gaok roosters (1.5-2 years old)…

Determination of puberty based on morphometric measurements and the gonadosomatic index of lovebird (Agapornis fischeri) testes
This study aimed to determine the relationship between age and testicular morphometrics in lovebird (Agapornis fischeri), as well as the relationship between age and the gonadosomatic index (GSI) of the testes, and to evaluate the effect of body weight on testicular weight in determining the onset…

Comparative serum biochemical and inflammatory profiles between repeat breeder and normal cyclic Holstein Friesian crossbred cows in Bangladesh
Repeat breeding syndrome (RBS) has adverse effects on dairy profitability in Bangladesh. This study compared serum biochemical profiles between RBS-affected and normal cyclic Holstein Friesian crossbred cows to identify potential metabolic biomarkers. A total of thirty-two lactating cows (3-8 years…

Leiomyoma of the broad ligament in an 8-year-old female Nigerian local pig (Sus scrofa): A Case Report
Leiomyomas are benign smooth muscle tumors most frequently arising from the uterus of intact female animals. Extra-uterine forms, including those originating from the broad ligament, are rare across species and hold diagnostic significance, particularly in older pigs. An 8-year-old, nulliparous…
