Breeding of rootstock sheep

Sheep body weights vary throughout the year according to the reproductive phase. Nutrient requirements are the lowest at the level of living, increasing from the beginning of pregnancy to the end of pregnancy, the highest level during lactation. In order to follow a successful feeding strategy, it is necessary to know the live weight and fitness scores (KS) of sheep in the following three periods:

However, the problems encountered in the reproductive performance of fatty animals are less than those of the weaker ones. Two weeks before the breeding and two weeks after the breeding, the sheep, if any, should be taken to quality pastures or fortified with 400-500g barley. This application is called flushing and is known to increase the lambing rate by 10-20%. Flushing is more effective on sheep with moderate condition. It is effective in early or off season lambing. Thus, the pastures of the maximum quality of the pasture lambs weaning time is increased by increasing the yield. Most postnatal deaths occur due to malnutrition within the first 25 days after birth. Therefore, sudden changes in the feeding regime of sheep should not be made until two weeks before the vaccination and from birth and weaning.

feed restriction should not be applied. Over 50% legumes pastures should be avoided during the breeding period. Because legumes contain a high percentage of estrogen hormones, they reduce the pregnancy rate. After breeding, sheep can be kept in pastures that are not of high quality until six weeks before lambing, they can be fed with hay or hay, because during this period fetal growth and sheep needs are minimal. The fetus grows 2/3 of the birth weight during the last six weeks of pregnancy from birth to birth. During this period, especially in sheep carrying more than 1 fetus rumen capacity is limited. For this reason, 400-500 g of barley is given to sheep in addition to normal feeding during the last 6 weeks of pregnancy to prevent adverse effects such as pregnancy toxemia, low birth weight lambs and low milk yield.


After lambing, energy and protein needs of sheep increase by 30 - 55%. If these needs are not met, there are situations such as loss of live weight, low milk yield, lack of care for the offspring and inability to grow lambs. Especially for multiple births, supplementation should be made for increased protein needs. If sufficient leguminous plants are not available, different protein sources should be addressed. As a general rule, for each lamb, sheep are given 350 g of concentrate or 400-450 g of grain. If the sheep are divided into groups according to the number of lambs (twins, triplets), the possibility of feeding more or less is eliminated.
