This study aimed to compare therapeutic efficacy of procaine penicillin, Phyllanthus emblica fruit extract and Cocos nucifera oil against subclinical mastitis, and its effects on milk composition. A total of 30 lactating beetal goats were selected, and divided into three groups (GA, GB and GC), each having 10 goats. GA was treated with procaine penicillin and GB with Phyllanthus emblica fruit extract while, GC with Cocos nucifera oil for five consecutive days. The milk sampling was done at pre-treatment (zero day), and post-treatment trial (7^th and 14^th day) aseptically. The evaluation parameters were CMT and bacteriological infection-based cure rate, milk pH, specific gravity, titratable acidity, electrical conductivity, total SCC, ALP and AP enzymes, as well as total milk yield. The cure rate of sub-clinically mastitic teats, based on CMT results was highest in GA (60%, 70%), moderate in GC (50%, 70%) and lowest in GB (50%, 60%) at 7^th and 14^th day respectively, while bacteriological infection-based cure rate was highest in GA (50%, 60%), followed by GC (40%, 70%) and GB (40%, 50%) at 7^th and 14^th day respectively. Further, with the treatment of Phyllanthus emblica fruit extract and Cocos nucifera oil, pH, electrical conductivity, total SCC, titratable acidity, ALP and AP enzymes of milk decreases, while milk fat and protein, specific gravity as well as total milk yield increases with time from zero day to 14^th day in all three groups (P < 0.05). So, it is concluded that Phyllanthus emblica fruit extract and Cocos nucifera oil are an inexpensive source used for treatment of subclinical mastitis, and also as substitutes to antibiotic therapy to produce antibiotic residue-free milk.

本研究旨在比较普鲁卡因青霉素、余甘子果实提取物和椰子油对亚临床乳腺炎的治疗效果及其对牛奶成分的影响。共选择30只泌乳甜菜山羊，分为三组（GA、GB和GC），每组10只山羊。GA 用普鲁卡因青霉素处理，GB 用余甘子果实提取物处理，GC 用椰子油连续 5 天处理。牛奶采样在预处理（零天）和后处理试验（7完成^日和14^日天）无菌。评估参数是 CMT 和基于细菌感染的治愈率、牛奶 pH 值、比重、可滴定酸度、电导率、总 SCC、ALP 和 AP 酶，以及总产奶量。根据 CMT 结果，亚临床乳头炎的治愈率在 GA 中最高（60%, 70%），GC 中等（50%, 70%），GB 最低（50%, 60%）在^第7 天和14^个分别天，而基于感染细菌学治愈率为在GA最高（50％，60％），其次通过GC（40％，70％）和GB（40％，50％）在第7^日和14^日天分别。进一步，用余甘子果实提取物和椰子的处理油、pH、电导率、总SCC、可滴定酸度、牛奶的ALP和AP酶降低，而所有三组的乳脂和蛋白质、比重以及总产奶量随时间从第0天增加到^第14天（P < 0.05)。因此，结论是余甘子果实提取物和椰子油是用于治疗亚临床乳腺炎的廉价来源，也可作为抗生素治疗的替代品，生产无抗生素残留的牛奶。
