Abstract

This study aimed to determine the addition of duck egg yolk in skim milk – fructose extender on sperm motility and viability of Muscovy duck (Cairina moschata) at 5°C storage. Ejaculates of Muscovy duck were divided into four portions equally. The first portion was for the control group (diluted in skim milk – fructose extender), and the second, third, and fourth portions were for the treatment groups of T1, T2, and T3 (diluted in skim milk – fructose extender added with 2.5, 5.0, and 7.5% v/v duck egg yolk). Sperm motility and viability were evaluated two hourly until the motility percentage reached 40%. The data were analyzed using ANOVA and Duncan test. The result showed that the highest percentage of spermatozoa motility and viability (p<0.05) was in the T2 group compared to the other groups. It could be concluded that the Muscovy duck semen extended in skim milk - fructose with 2.5 to 7.5% egg yolk of duck qualified for artificial insemination at storage up to 10 hours in 5°C storage.

Abstract

This study aims to determine the factors related to uterine prolapse in beef cow in the Besuki Animal Health Center working area in Situbondo regency. The sample consisted of 100 cows that calved in 2020-2022, whose data was obtained from the Department of Animal Husbandry of Situbondo regency, East Java, Indonesia. Determination of the months of the rainy and dry season was obtained from the Meteorological, Climatological and Geophysical Agency, Juanda Class I Meteorological Station. Other data regarding breed, age, parity of cow and dystocia incidence in cow was obtained by conducting interviews with farmers followed by confirmation with inseminator records, and direct observation of the housing system. The collected data were cross-tabulated and analyzed using Chi-square analysis to determine possible factors causing uterine prolapse. The results showed that the incidence of uterine prolapse in beef cow in the working area was 35% (35/100). The factors of housing, age, parity, and incidence of dystocia were significantly related (p <0.05) to the incidence of uterine prolapse, while breed and season did not have a significant influence (p > 0.05). It could be concluded that the age and parity of the cow at the time of calving, the practice of housing cow, and the incidence of dystocia were related to the incidence of uterine prolapse in cows in the Besuki Animal Health Center operational area.

Abstract

This study aimed to evaluate the association of factors such as nutrition, thermal humidity index (THI), age, and lactation period with the occurrence of repeat breeding of dairy cows. The sample consisted of Holstein Friesian cows aged 1-11 years, with lactation periods ranging from 1 to 7 months, currently in lactation, and experiencing repeat breeding (inseminated three or more times without conception, despite exhibiting normal estrous cycles and intervals). The results showed that feeding practices by farmers did not significantly differ (p >0.05) in relation to the incidence of repeat breeding. THI values recorded in several barns also showed no significant differences (p >0.05), with the cows experiencing light to moderate heat stress. Similarly, the frequency of artificial insemination and the estrous cycle intervals remained within the normal range. The highest incidence of repeat breeding was observed in cows aged 2.5 to 5.5 years, accounting for 78.13%, and during lactation periods of 1-3 months, accounting for 81.26%. It can be concluded that there were no significant differences in the provision of forage and leguminous feed between normal cows and those with repeat breeding, and the crude protein content of forage did not influence its occurrence. Additionally, there was no indirect relationship between THI and repeat breeding. However, the incidence of repeat breeding tended to increase in cows aged 3-4 years, and during the second and third lactation periods.

Abstract

Predicting the turtle's reproductive status and sexual maturity is necessary for ex-situ breeding and conservation program. The histology of the seminiferous tubules of the Indonesian box turtle (Cuora amboinensis couro) at various ages has not been studied much. This study aims to develop equations to predict the sexual maturity of Indonesian box turtles based on straight carapace length (SCL). Six turtles with SCL sizes 10-21 cm were sacrificed and their testes were taken for morphometric measurements and histological preparations for Hematoxylin Eosin staining. Pearson's correlation of SCL with testicular maturity parameters was analyzed, followed by Anova Regression. The results showed that there were differences in the morphometry and topographic anatomy of the Indonesian box turtle testes between SCL below 15 cm and above 15 cm. Six turtles with SCL size of 10-21 cm were sacrificed and their testes were taken for morphometric measurements and histological preparations for Hematoxylin Eosin staining. Pearson's correlation of SCL with testicular maturity parameters was analyzed, followed by Regression Anova. The results showed that there were differences in the morphometry and topographic anatomy of the Indonesian box turtle testes between SCL below 15 cm and above 15 cm.
