Relationship between sows' backfat and reproductive performance
As we all know, the best body condition of sows is very important to increase the number of litters born in sows and sows. With the development of pig breeding at home and abroad and the improvement of genetic breeding, the breeding potential of sows has become very large. To improve, it is necessary to constantly increase the amount of sow lactation to feed more piglets. The good health and good body condition of the sow are prerequisites for ensuring milk production. How to achieve the best performance by measuring and testing the sow body condition. Pregnancy and lactation are the two major stages of sow body condition changes. The basic goal of the farm is to maintain the stable body condition of the sow in the breeding herd. Many large-scale pig farms and even large-scale farming technicians use their own breeding experience to evaluate the sow's lyricism with naked eyes and classify it into 1 to 5 levels for body condition scoring. At first glance, this seems like a good method. However, there are many misunderstandings. In fact, it is difficult to evaluate different breeds of pigs on different farms, and there are various changes between them. For example, a sow assessing her backbone as lean by eye, but may actually measure the measurement, and her sensation is within the normal range. In order to improve the accuracy of the eye's body condition score, a backfatometer was used to perform an overall assessment of the sow. This can be a great help. When measuring backfat thickness, read at the 10th rib of the sow, 6.5 cm from the midline of the dorsal midline, usually called P2. Metal or hard plastic stencils can be used to ensure that readings are taken at the same location each time. Scanning measurements When the backfat thickness is thick, there are 3 major periods that can help the pig farm to evaluate the herd and ensure that the sows and the primiparous sows maintain the best body condition. The three main periods are: at weaning, 4 weeks after mating, 1 week before birth. Sows are recommended to be back-fed at 16-18cm before birth and 13-15cm after birth. However, because the body tissues of the first-born sow are continuously growing and developing, it is recommended that the prenatal backfitter be slightly higher than the sow, about 19cm. Because there will be some differences in each farm, it is recommended that the farms can grope based on the actual situation, to determine the back lick of the sows in the upper delivery room. When the peak of lactation, select the best sow to do the secondary determination and determine the sow's upper delivery room. Before the best condition, at the same time to do a good job tracking. Establish a database of the farm itself to ensure optimal breeding performance of the sow.
