Abstract
Gene expression at the phenotypic level varies due to a number of influences
from the environment in which the animals are reared. Ignoring this reality
or due to insufficient knowledge, farmers are often disappointed when
choosing a population of sheep when they do not get the production results
that the breed achieves where they bought it. The investigation of the
reproductive and production characteristics of parent herds of Sjenica sheep
was conducted on four farms. In the research, it included a total of 921
lambs and 474 sheep. The influence of sheep body weight on the weight of
lambs at birth within a farm was analyzed. Based on the research conducted
on the sheep population and after the obtained and processed data, we can
state the following: certain differences were found in the fertility of
sheep depending on the farm and body weight. We also perceived that certain
differences in the body weight of the lambs are evident depending on the
weight group of the sheep and the farm where the sheep were raised. All of
the above leads us to the general conclusion that management is extremely
important in sheep farming. If the selection of the breeding population is
carried out correctly and adequate measures of keeping, nutrition and
reproduction are applied, success is guaranteed.
