The objective of this study was to compare effects of products derived from soybeans, with different oil content, on milk production and some, more important indicators of metabolic profile, during the middle period of lactation. The experiment was conducted on two groups of Holstein cows. There were 15 cows in each group. The ration of the control group of cows (I), was based on equal amounts of full-fat and low-fat (expeller soybeans meal), heat treated soybeans. Cows in experimental group (II) were received ration, wherein full-fat heat treated soybeans, was completely replaced with expeller soybeans meal (Biopro 60). At the end of experiment, milk production in control group of cows was 29.95 kg with butterfat content 3.54%, while in the experimental group it was 31.47 kg of milk with the butterfat content 3.45%. The differences of mentioned parameters were not statistically significant (p is greater than 0.05), nor in the case of protein content which was 3.50% in control group and 3.48% in experimental group of cows. According to achieved results it can be concluded that is possible to improve production, when nutrition of cows is based on soybean products with lower fat content, during the middle period of lactation.
