The productivity of animals is closely related to the quality of the diet and of dry matter intake. Dry matter intake (DMI) is a factor that needs to be assessed before an animal’s diet can be calculated correctly. Purebred bulls of the Kazakh white-headed breed in the amount of 70 heads of 7-8 months of age were selected for the experiment. By the end of the test, the bulls were about 11-12 months old. The average weight of the bulls when put to the test was 248.47 ± 2.46 kg, at the end of the test their average weight was 319.7 ± 3.44 kg. It is worth noting that the largest average daily increase was 2.46 ± 0.05 kg, which was in a bull that consumed 6.26 kg of dry matter per day, while the lowest average daily increase was 0.36 ± 0.05 kg, which was in a bull that consumed 5.67 kg of dry matter.
