Abstract

This study aimed to identify female goats with the potential to give birth to triplets by examining morphological characteristics correlated with FSH and LH hormone levels in the blood. It included four triplet-bearing Boer goats and four triplet-bearing Etawah grade goats, each with 12 kids, and four single-bearing Boer goats and four single-bearing Etawah grade goats, each with four kids. Morphological indices of body sizes, including weight, height slope, length index, width slope, depth index, foreleg length, and hormone levels, were observed. A t-test and descriptive analysis were conducted. The average body size of Boer goats was larger than Etawah grade goats, but there were no significant morphological differences between triplet-bearing Boer and Etawah grade goats. However, single-bearing Boer goats had a significantly higher height slope than single-bearing Etawah grade goats. FSH levels significantly increased in the blood of triplet-bearing Boer goats compared to single-bearing Boer goats. Morphological indices and hormone levels can help select goats likely to give birth to triplets.

Abstract

Observation of body size can be used as an identification of breeders as a selection criterion of dairy goats identify superior breeding stock and optimize milk production in Nusa Tenggara Barat, with potential implications for food security. The study aimed to determine the relationship between body size and udder volume with milk production of Etawa Crossbreed goat. This study was conducted at the experimental pen of Universitas Nahdlatul Wathan Mataram in Desa Ketangga Jeraeng, Lombok Timur, with twenty-five female Etawa Crossbreeds that were lactating. This study used a survey method and measurements of body length (BL), body height (BH), chest circumference (CC), udder volume (UV) and milk production (MP). Data were analyzed using correlation and linear regression analysis. The results showed that the average of BL = 72.76 cm, BH = 66.6 cm, CC = 73.24 cm, UV = 30.31 liters and MP = 327.76 ml / day. Body length and udder volume were moderately correlated with milk production (r = 0.40-0.59). While body height and udder volume had a strong correlation with milk production (r above 0.60). From the results, it can be concluded that body length, body height and udder volume had a significant effect on milk production, and there was a positive correlation with udder volume and milk production which was classified as a moderate correlation (r = 0.40-0.59).
