The relationship between dry matter intake and the average daily gain

Abstract

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.
