Abstract

Farmers in Enrekang, South Sulawesi typically feed their goats with Gliricidia maculuta as a sole diet. This may cause a problem due to asynchrony of nutrient availability in the rumen,especially the availability of energy and protein, which could lead to poor milk yield in terms ofquantity and quality. The purpose of this research was to study the effect of providing multi-nutrientblock (MNB) on the physical and chemical characteristics of goat milk. Ten Ettawa crossbred goatson the 3rd-4th month of their lactating period were randomly divided into two groups (fivegoats/group). Each group was either fed on Gliricidia maculata/control (ration C, a ration typicallyused by Enrekang farmers for feeding their goats) or fed on C + MNB (CM). MNB was formulatedfrom locally available feedstuff and was provided at the level of approximately 500 g/head/d. Theresults of the study showed that provision of MNB did not significantly (P>0.05) improve milk yield,i.e. 198 and 274 ml/d for C and CM, respectively. The treatment did not significantly (P>0.05) affectphysical characteristics, i.e. pH and specific gravity of the milk. Similarly, provision of MNB did notsignificantly (P>0.05) alter chemical composition, i.e. total solids, crude protein, fat, carbohydrate,lactose, mineral, Ca, and P of the milk.  In conclusion, there was no significant benefit on providingmulti-nutrient block for goats consuming Gliricidia maculuta as a sole diet in terms of physical andchemical properties of the milk, but there was a tendency that provision of MNB may improve yield,crude protein and fat of goat milk.Key Words: Multi-Nutrient Block, Protein of Goat Milk, Fat of Goat Milk, Total Solids of Goat Milk, Gliricidia maculata

Abstract

Principal component analysis (PCA) is commonly used to examine the relationship among mor-phometric traits and determine which traits effectively describe the body conformation. This study evaluated the morphometric traits of Katjang, Boer, and Katjang × Boer goats through PCA to identify key indicators of body conformation and productivity. A total of 375 does (100 Katjang, 153 Boer, 122 Katjang x Boer) aged 1.5–2 years were measured for body weight (BW), body length (BL), chest depth (CD), chest girth (CG), height at withers (HW), width at withers (WW), hip height (HH), and rump width (RW) raised under semi-intensive management at MARDI Kluang, Malaysia. Results revealed significant (P < 0.05) interbreed differences, with Boer does exhibiting superior size (BW: 39.95 ± 2.22 kg; CG: 80.77 ± 3.96 cm) and Katjang x Boer does showing intermediate values (BW: 32.35 ± 2.65 kg; CG: 70.10 ± 1.63), reflecting heterosis effects. PCA identified two principal components (PCs), with PC1 (57.8–64.0% variance) strongly correlated with CG (0.89–0.94), BW (0.85–0.90), and BL (0.80–0.85), while PC2 (16.0–17.8% variance) distinguished taller/narrower (positive HH/HW loadings) from shorter/wider conformations (negative RW/WW loadings). Boer goats had the highest PC1 eigen-value (5.12), confirming their robust frame. Chest girth emerged as the most reliable predictor of BW (r = 0.85–0.89, P < 0.01), supported by high communality values (0.81–0.89). Body index classifica-tion placed Katjang in the brevigline group (BI: 81.45 ± 2.34) while Boer and Katjang x Boer does in medioline (BI: 85.12–86.51), aligning with their meat production potential. These findings underscore CG utility in selection programs and highlight the conserved morphological integration across breeds, offering practical benchmarks for genetic improvement under Malaysian climate.
