THE EFFICIENCY OF ONE-YEAR LEGUME AND CEREAL MIX HAY FOR HEIFERS FEEDING
An important problem of the full feeding of young cattle is the provision of including in their diets feed protein as a main limiting factor of nutrition. Protein deficiency is a major cause of feed overgrowth and stunted growth and development.
The possibility of replacing corn silage by one-year vetch and oats hay has been proved in order to increase the protein nutrition of the heifers.
Chemical composition, energy nutrition of corn silage and one-year vetch and oats haywere studied. Analysis of the chemical composition of the dry matter of the test feeds showed that crude protein and crude fiber content complied with the firstclass requirements.However, corn silage was classified as the third class. The level of crude protein in dry matter of one-year vetch and oats hay was 15.36%, in corn silage it was 7.24%. The proportion of soluble protein fractions in hay was by 8.77% higher than in corn silage. Hay was also characterized by a higher content of readily soluble carbohydrates; theycaused the improvement of the sugar-protein ratio in the diets of heifers.
The oat and vetch hay had low acidity, the pH level was 5.26, the ratio of lactic acid to acetic acid was 2.7: 1; in corn silage, the proportion of lactic acid exceeded the acetic level by 1.6 times. The nutritional energy of 1 kg of hay dry matter amounted to 8.17 MJ of exchange energy, which is 0.49 MJ more than that of corn silage.
The productive effect of corn silage and oat and vetch hay was investigated in 2groups of Ukrainian black-and-white milk breed heifers. The animals of the control group received corn silage (55% in the diet with concerning energy nutrition).In the diet of the experimental group, it was replaced by oat and vetch hay. The ration of the experimental animals had higher protein and carbohydrate nutrition, it had a positive effect on feed intake and growth rates. The average daily weight gain of the calves of the experimental group has increased by 7.6%; feed costs by 1 kg of increase have decreased by 7.1% for 155 days of the experimental period.
