8.1.2.3 Feeding for Reproduction Reproduction stages include tupping and pregnancy. If the animals are under optimum nutritional state, they come into 1st oestrus at 10 to 12 months of age. Otherwise it starts at about 15 months of age. Under Indian conditions one and half year age is considered as the breedable age. Flushing Flushing is conditioning of ewes for breeding. If the ewes are in low plane of nutrition prior to breeding, additional supplementation for about one month has beneficial effect in bringing the ewes into oestrus. Even without additional supplementation when there is flush green pasture, there is flushing effect. Supplementation of about 250g of concetrates could bring about flushing of ewes quite well. If the plane of nutrition of the animal is good prior to breeding, flushing is not at all needed. Feeding during pregnancy If the ewes are flushed and good grazing is available, no additional supplementation is necessary during early pregnancy upto about 14 weeks of gestation period. During advanced pregnancy (last 6 weeks ) however, extra feeding is essential. The consumption of energy, protein and other nutrients should be 50%. During this stage, there is also depression in the intake capacity and feed digestibility. Hence highly digestible feed need to be fed during this stage. 8.1.2.4 Feeding during lactation As already indicated, during the lactation the requirements are twice the requirement for maintenance of the animals. It is not possible to provide the nutrients required by the mother for optimum growth of the nursing lamb from all forage rations. Hence supplementation with high energy feed is essential. A diet with 40% concentrate and 60% roughage would be appropriate for the lactating ewes. A reduction in the concentrate allowance would adversely affect the growth of the lamb. Adequate quantities of minerals and salt are to be provided both to the pregnant and lactating ewe. An ideal system would be to graze them in separate paddocks and provide them additional supplement as per the need after grazing. However, this has not been possible in most farms in our country and every effort should be made to adopt the system. The later part of pregnancy (Last 4 to 6 weeks) and early lactation period, 4 to 6 weeks post partum is most critical for the ewe as well as for the lamb. Higher amounts of energy and protein should be provided to the ewe during this period. The nutrient requirement increase by about 50% during late pregnancy and by about 100% during lactation over the maintenance requirement of the ewe for the growth in lambs. A feeding schedule for different categories of sheep is given in Table 8.7. Table 8.7 Suggested Feeding Schedule for Different Categories of <strong>Sheep</strong> I. Exotic sheep 1.
