Abstract: In order to explore the effect of the degree of tooth cutting on the growth and development of piglets. In this trial, 6 lactating sows delivered within 1 week were selected. The 54 piglets produced were randomly divided into a neat group, a non-aligned group and a non-cut group, with 18 in each group. Each of the three teeth is neatly cut, three teeth are not neatly cut, and three teeth are not cut. They are marked with ear tags. The results showed that the daily weight gain of the neat group was 7.9% and 9% higher than that of the non-aligned group at 10 and 30 days respectively. The daily weight gain of the neat group was higher than that of the non-cut group at 10 and 30 days respectively. 0.9% and 1.2%. There were 6 piglets biting the nipples in the non-cutting group, and 4 piglets biting the nipples in the irregularly-cut group. In the non-cutting group and the incisor-cutting group, 6 piglets were bitten in the face, but there was no phenomenon in the neat group. Studies have shown that the degree of tooth decay in piglets has a serious impact on their growth and development, lactating sows and the entire herd.
In modern large-scale or intensive pig production, piglets play an important role in the production of pig farms, and the piglet breeding management stage is the key to production. The management level of piglets affects the success or failure of pig production, and also marks the economic benefits of raising pigs. After birth, piglets face a series of treatments such as cutting teeth, breaking tails, earrings, and castration. The earliest documentary technique of piglet cutting in China was recorded in the book “Qi Min Yao Shu” in the Northern Wei Dynasty. “After six days after the three days, the tail is smashed sixty days later”, which means cutting the teeth and then cutting the tail before cutting the pig. It is to avoid death caused by disease caused by piglets being cut or broken.
The suckling piglets are the material basis for the development and production of the pig industry. From the genetic point of view, the growth traits of the piglets reflect the breeding effect of the ancestors. The feed management stage of suckling piglets is an important period for the growth and development of piglets. The digestive function of suckling piglets is still not perfect and the feed requirements are high. Reasonable nutrient ratio is the key factor to ensure the normal growth and development of piglets, improve production performance and reduce mortality.
The piglets began to have long pre-milk teeth at 1 week of age, and 2 weeks old long-cut teeth, which had grown well before birth. Piglets have been born with fangs and caries. When piglets are eating milk, they fight for nipples and the dogs fight each other to bite their cheeks. Once infected by bacteria, they will become infected and will affect their milk consumption. When the piglets are vying for milk, the sows that cause damage to the sow’s breasts and cause breast pain frequently lie down and step on the piglets. Pigs have a fighting phenomenon during breastfeeding, which seriously affects the quality of breeding and breeding. When the piglets are teething, they are itchy, and they like to use grass, fences, stools and other contaminants to bring pathogens into the body, causing jaundice and white sputum. In view of this, in order to ensure the normal breastfeeding of the sow, the piglet should be cut at the birth of the piglet according to its physical condition. In the aspect of piglet care, it is necessary to improve the hygiene of the column, strengthen the frequency of disinfection with pigs, feed early, start eating, and keep the bar dry. This will improve the digestion and absorption capacity of piglets, feed utilization, and reduce jaundice. White cockroaches are crucial.
In recent years, the development of large-scale and intensive pig raising has made the breeding density of pigs more and more large, and the cutting and cutting work of piglets is indispensable in production. The appropriate time for piglets to cut their teeth should be when the piglet is born, because the pig’s teeth are still soft, and it is not easy to be broken or irregular. With the development of the pig industry, in order to prevent the suckling piglets from injuring the sow’s nipples and breasts, or the biting between the piglets due to the nipples, or biting the tail due to the eclipse, the practice of aquaculture production is practiced. It is common to perform operations such as tail cutting, tooth cutting, and ear tagging on newly born piglets.
