Abstract

Sapera goat is a dairy goat resulting from a cross between a Saanen buck and an Ettawah cross doe. These small ruminants are reared by rural households for poverty reduction and undernutrition prevention. Breeding of Sapera goat through artificial insemination (AI) technique was expected to accelerate the increase in population. Unfortunately, the frozen semen of Sapera buck is not available yet. This study aims to determine the effect of the distance between semen straw and liquid nitrogen surface during pre-freezing process on the quality of frozen semen of Sapera goats. Semen was obtained from 1.5 years old Sapera buck. The ejaculates were diluted in tris-egg yolk extender to obtain a concentration of 120 x 106 spermatozoa/mL, then equilibrated at 5°C for one hour. The extended semen was packaged in 0.5 mL French straws (60 x 106 spermatozoa/straw). The filled straws were pre-frozen in the cold handling cabinet (Minitube, Germany) held at 10, 11, 12, 13, 14, and 15 cm above liquid nitrogen respectively for T1, T2, T3, T4, T5, and T6 groups, each with four replicates. After pre-freezing for eight minutes the straws were immediately plunged, and stored in liquid nitrogen (-196°C) for two days, followed by quality assessment. The best post-thawed motility (41.75 ± 2.06 %), viability (49.00 ± 0.82 %) and morphological abnormalities (4.75 ± 0.96 %) were obtained from pre-freezing stage with a distance of 10 cm. It could be concluded that in tris-egg yolk extender, post-thawed spermatozoa viability and motility of Sapera buck were qualified for AI when fresh semen was pre-frozen at 10 cm distance of straws from the surface of liquid nitrogen for eight minutes.

Abstract

Mastitis is a persistent and economically significant health problem in dairy goats in Banyuwangi, East Java, where smallholder production systems dominate. This review synthesises current evidence on the primary risk factors contributing to the high prevalence of subclinical mastitis in the region. Local studies consistently report Staphylococcus aureus as the leading etiological agent, frequently exhibiting antimicrobial resistance linked to unsupervised antibiotic use. Host-related factors such as advanced parity, udder lesions, and teat-end damage increase susceptibility to intramammary infection. Management practices—including inadequate milking hygiene, use of shared towels, absence of pre- and post-dipping, and irregular equipment sanitation—facilitate the transmission of contagious pathogens. Environmental conditions, particularly high humidity and poor housing sanitation, further elevate infection pressure. Socio-economic constraints and limited farmer knowledge about subclinical mastitis and antibiotic stewardship exacerbate disease persistence. The multifactorial nature of mastitis in Banyuwangi underscores the need for context-appropriate interventions combining improved hygiene practices, better housing management, routine screening, and responsible antimicrobial use. Strengthened farmer education and targeted surveillance are essential to reduce mastitis prevalence and enhance the sustainability of goat dairy production in the region.

Abstract

This study aimed to evaluate the differences in blood profile of erythrocytes, hemoglobin, and PCV in Indonesian simental and limousin beef cattle in highlands and lowlands. Banyuwangi is one of the beef cattle contributors in East Java with its highland and lowland topography. This research was conducted from July to August 2023. The research was conducted in 3 locations namely highlands (Kalibaru), lowlands (Rogojampi) and sample examination in Airlangga University Banyuwangi. Animals used in this study were Indonesian simental and limousin beef cattle with 1-2 years of age as many as 15 heads in the highlands and 15 heads in the lowlands. The research method used was purposive sampling. Blood samples used in this study used Indonesian simental and limousin beef cattle blood taken using venoject and inserted in EDTA tubes and examined using a Hematology Analyzer. The variables observed in this study were the number of erythrocytes, hemoglobin, and PCV. The data obtained were processed with Independent T-test data analysis. The results showed no significant difference in erythrocytes and PCV, but there was a significant difference in hemoglobin levels. The conclusion of this study is that Indonesian simental and limousin beef cattle in the lowlands experience mild anemia.
