ABSTRACT: Inclusion of feed additives in the winter diet of pregnant mares increases the consumption of crude protein on 3-21%, for digestible 4-32%. In the summer experience, when grazing on alas and valley meadows Yakut mares consume an average of 330 g per day of crude protein per day on 100 kg live weight 211 g of digestible protein. This is according to 5 experiments. In winter, the consumption of crude protein was at 209 g per day per 100 kg live weight on digestible protein, 136 g for an average of four experiments with data on natural herbage of winter pasture. During summer, the horses’ body is intense accumulation of reserve elements, increasing fatness, first by increasing muscle mass, further due to the deposition of subcutaneous fat and visceral fat in the abdomen. At this time in our experiments mare consumed 330 g per day on 100 kg live weight.
