The adaptability of Garut sheep grazing on oil palm and rubber plantations in tropical conditions of Indonesia.

Background And Aim: The productivity of sheep in humid tropical plantation areas relies on their ability to adapt. Oil palm plantations serve as potential grazing lands for livestock. This study aimed to identify Garut sheep adaptations in oil palm and rubber plantations of the Garut district, West Java, Indonesia.

Sumbawa cattle: a study of growth hormone (GH) gene variants and their association with biometric traits.

The growth hormone (GH) gene plays a vital role in regulating animal metabolism and body size, making it a potential candidate for influencing livestock performance. This study aimed to investigate the polymorphisms within the GH gene and their associations with 10 biometric traits in the Sumbawa cattle population of Indonesia. Biometric trait data and blood samples were collected from 112 Sumbawa cattle individuals, and their GH gene sequences were analyzed using two sets of primers for amplification.

Biodiversity of Indonesian indigenous buffalo: First review of the status, challenges, and development opportunities.

In Indonesia, the buffalo is important for small and marginal farmers' livelihood and economic development as a source of food, working animal, and tourist attraction. Therefore, an in-depth study is needed to examine challenges and opportunities for buffalo development in Indonesia. In Indonesia, the buffalo is divided into two types: swamp buffalo and river buffalo.

Peri-parturient rise in faecal strongyle egg counts of different genotypes of sheep in North Sumatra, Indonesia.

Faecal strongyle egg counts were monitored in peri-parturient ewes and dry ewes grazing in a rubber plantation in North Sumatra, Indonesia. A significant rise in faecal egg counts was observed during the post-parturient period. Haemonchus contortus was the dominant species in the faecal cultures of the lactating ewes.

Comparison of resistance of four genotypes of rams to experimental infection with Haemonchus contortus.

Fifty-five rams aged about 18-24 months weighing 30-42 kg were used in this study. Ten rams of each of four genotypes, S (Sumatra), H1 (50% Sumatra-50% Virgin Island), B1 (50% Sumatra-50% Barbados Blackbelly), E1 (50% Sumatra-50% Java Fat-tail), were infected orally with a newly isolated strain of Haemonchus contortus. Each animal received 2000 infective larvae 3 times week-1 for 3 weeks, with a total of 18,000 larvae.
