Farmers generally prefer to treat ewes in the management of flocks, especially pregnant ewes. Feeding and the environment must be managed to prevent illness. The standards for feeding ewe in different periods of pregnancy will also vary greatly, such as nutrients and feed quality, so what are the feeding standards for ewe in different periods of pregnancy?
First, feed management
1. The concentrate composition of the ewe is: corn 10.0%, bran 5.0%, flax cake 7.5%, sunflower cake 5.0%, stone powder 2.0%, salt 1.5%, trace elements 1.0%, vitamin 0.5%.
2, ewes mixed concentrate: 0.2-0.3 kg, hay 0.3-0.5 kg, straw 0.5-0.7 kg. For sheep with poor constitution and thin body, it is necessary to increase the supply of mixed concentrates so that the ewes reach 7-8 percent before breeding, and they must grasp the sensation.

Second, feeding standards
1. The ewe is about one month after the pregnancy. The fertilized eggs are easily affected by external feeding conditions before the colonization is formed. If the ewes are fed with metamorphic, moldy or toxic feed, it is easy to cause early embryo death. If the diet of the ewes is not comprehensive, lack of protein, vitamins and minerals, it will cause the fertilized eggs to stop developing in the middle. Therefore, the feeding and management is the key period to ensure the normal growth and development of the fetus in the first month of pregnancy.
2. After the ewe is pregnant for two months, as the pregnancy month increases, the fetal development gradually accelerates. The amount of concentrate should be gradually increased. Soy beans, corn, barley, and wheat can be soaked in warm water for 6 hours to 8 hours. Grind into pulp, add the equivalent amount of feed such as soybeans, bean cake, bran, salt, bone powder, feed the pregnant sheep 2 times to 3 times a day, each time each sheep is fed with mixed concentrate, young ewes Also increase the amount of concentrate feed.
3. After the ewe is pregnant for three months, the amount of forage should be properly controlled. Feeding the sheep with forage and adding concentrate should be done with less feed to prevent excessive feeding of the fetus. It affects its normal growth and development.
4. After the ewe's pregnancy for four months, the weight of the fetus has reached 60%~70% of the weight of the lamb at birth. At the same time, the ewes need to store certain nutrients to prepare for postpartum breastfeeding. Generally, the feeding of the abortion is carried out at this stage, and the feeding amount of the concentrate should be increased to about twice that of the pre-pregnancy period, while the forage and feeding concentrates to be fed should be fresh, diversified, and young grasses. Green and juicy feed such as carrots can be fed more. It is forbidden to feed potatoes, distiller's grains and undetoxified cotton cakes or rapeseed cakes, and it is forbidden to be mildewed, too cold or overheated, too acidic or mixed with ergots and poisonous grasses (such as scented flowers, thornless mimosa) Feed, etc., so as not to cause abortion, dystocia and post-production diseases.
5, the ewe should be properly controlled about one month before the birth, feed the soft feed as much as possible, such as nitriding, micro-storing or salinizing straw, green and juicy feed, adding bran to the concentrate The amount of skin is fed to facilitate the benefit of the intestines.
The above is the feed management and feeding standard for the ewe's pregnancy. The ewe is more expensive to consume and the nutrition must be increased. At this time, the management of the ewe is also very important. The farmers must pay attention to avoid the improper feeding. The necessary losses, I hope the above can help the sheep farmers.
