Productivity and blood biochemical profile of first-calf heifers at increasing feed levels
Submitted by Гость (not verified) on Mon, 07/29/2024 - 22:38High productivity and longevity of animals are the key challenges in modern dairy farming. In addition to high milk yields, first-calf heifers also have to increase their body weight. Due to their physiological characteristics, they are unable to consume large amounts of bulky forage to provide energy and nutrients for potential productivity. One of the ways to solve this problem is to increase the feeding level of first-calf heifers at the expense of concentrates.
