The effect of supplementation of dairy cows with cottonseed, sunflower seed and soybean on the liver was studied. The basic ration was equal for all groups and consisted of 20 kg maize silage, 10 kg pea-barley haylage and 2 kg alalfa hay. Additionally, the cows of each groups received dietary supplements as followed: group 1(cotrol) - 3 kg grounded corn and 3.6 kg sunflower meal daily; group 2 - 3.5 kg cottonseed and 2.5 kg sunflower meal, group 3 - 2.3 kg sunflower seed, 3.0 kg sunflower meal and 0.8 kg grounged corn, group 4 - 4 kg soybean and 1 kg grounded corn. Study specimens were obtained by liver biopsy, done after the first and the second month of feeding the experimental diets. In addition, cows from group 2 provided study samples after five months of feeding and 2 months after feeding cessation. Cows given cottonseed for one month exhibited granular dystrophy and initial fatty infiltration of the liver, after a 2-month feeding. After 5 months, a high degree of fatty liver dystrophy was present. The feeding on sunflower seed did not result in any significant changes. The feeding on soybean resulted in moderate liver granular dystrophy.
