Popis: Sufficient nutrient availability in the early period of lactation is needed to improve and to optimize milk production and composition of dairy cows. The objective of this study was to evaluate milk production and chemical composition of crossbred Friesian Holstein fed by diet containing protected soybean groats as feed supplement. Soybean groat was protected by 1% formaldehyde. It was supplemented to three groups of treatment consisted of basal diet (P1), basal diet supplemented by 2% protected soybean groat (P2), and basal diet supplemented with 4% protected soybean groats (P3). A total of 15 lactating dairy cows (crossbred Friesian Holstein) were used in this study. They were equally grouped into three different treatments. Milk samples were measured using milk scan and they were statistically analyzed using the R programing. Duncan’s multiple range test (DMRT) was also applied to distinguish among treatments. The results showed that supplementation of protected soybean groats significantly affected fat and protein contents. Cows treated by diet supplemented with 4% protected soybean groat was found containing highest milk fat percentage. In addition, protected soybean groat supplementation in the diet statistically increased milk proteins. Lactose in the milk was not affected by treatment. In conclusion, supplementation of protected soybean groat in the crossbred Friesian Holstein diet improved milk chemical quality.
