Sažetak
Sheep and goat milk producers often feed animals a meal with an unfavorable ratio between digestible proteins and energy in order to obtain a higher milk yield per animal. As a result, the fertility of small ruminants and the amount of milk produced during lactation are often lower, the processing characteristics of the milk are poorer, and, in addition, the increased excretion of nitrogen into the soil also pollutes the environment. One of the relatively simple ways to determine a balanced ration for dairy cattle is to determine the milk urea concentration. Unlike cow's milk, the optimal urea concentration in goat and sheep milk has not yet been defined. Due to the numerous specific sources of variability, such as apocrine secretion, reproductive seasonality, or different breeding systems in small ruminants, it is not easy to determine the optimal value. Therefore, it is not surprising that relatively few data on the relationship between urea concentration and production and processing indicators for goat and sheep milk can be found up to date.
