Feeding management skills for gilts

First, full feeding stage: 20-60 kilograms is to promote the full development stage of gilt body, should be fed according to the appropriate feeding standards full nutritional full-priced diet.

Second, the restrictions on the rearing phase: lean-type sows are generally limited in the 90-110 kg began to eat, fat-type fat and fat sows can start to limit food in 70 kg, feed the amount of the daily feed of about 2% of body weight - 2.5%. The gilts were given a limited amount of feed two weeks prior to the start of breeding, and supplemental aphrodisiac was added to increase the number of ovulation.

Third, rational grouping and moderate exercise. In order for the gilts to grow well, they should be bred according to the body weight and be reared in small groups. Before the 60 kg weight, 4-6 heads can be kept in each column. After 60 kg, the weight should be divided into 2-3 heads for a small group. It is good for early estrus breeding. The gilt house should have an outdoor sports field to strengthen the body and enhance the flexibility and firmness of the limbs.

Fourth, timely training. The gilts have to emphasize teaching and management since childhood, establish a harmonious relationship between humans and pigs, and train pigs to develop good living habits. After being raised to a certain age, sexual maturity will be reached and there will be periodic estrus. However, the body has not yet fully matured. Sows are best exposed with adult boars at 150-180 days of age to promote estrus.

Fifth, daily management. The suitable temperature for gilt house is 19-21 °C. In summer, it is necessary to pay attention to sunstroke prevention. Once the room temperature exceeds 30°C, the secretion of sex hormones in the gilt will be inhibited, resulting in non-estrus or estrus. In winter, it is necessary to strengthen the ventilation of the pig house. To deal with the contradiction between temperature and ventilation, it is necessary to maintain the proper temperature while ensuring fresh air. Shelter environment and facilities and equipment should be regularly disinfected, and pigs should be frequently brushed and periodically dewormed.

Six, strictly enforce the immunization program. According to the immunization program, immunization work on foot-and-mouth disease, swine fever, parvovirus disease, pseudorabies, Japanese encephalitis, and blue ear disease can be performed in time.
