According to practical experience, talk about the main points of sow feeding and management techniques in summer:
1. Do a good job in pig house hygiene and improve the disinfection process.
Traditional pigs pay attention to "cooking and feeding," and they say that pigs should be cleaned and kept clean. The feces of nursing sows should be cleaned in time. The personnel are in and out of the vehicle and the vehicle is in and out of the site for strict disinfection. Rules and regulations are established, and management personnel take the lead in observing.
2. Do a good job of sunstroke cooling for sows. Summer temperatures are high, and sows, especially sows, are sensitive to heat stress, have reduced fertility, have fewer ovulations, have more stillbirths, and have increased mortality. Summer should be done to prevent heatstroke, increase ventilation, spray and other measures; to build pergola in the stadium, set up shade nets, wash the body with cold water or add spray settings, spray 4 times a day to 6 times; conditional farms can be Install wet curtain cooling system. It is best to take the drip cooling method in the nursing home sow, drip in the neck near the shoulder.
3. Do a good job in farm greening.
As far as possible, choose to build sites in areas where there are more trees, plant trees in front of pig houses, adjust and improve the microclimate environment in the area, reduce heat radiation in summer, and release oxygen. Doing a good job in greening the pig farm can reduce the ambient temperature of the pig house from 3°C to 4°C in the summer and reduce heat radiation by 80%.
4. Adjust the feed formulation to ensure that the nutritional level is appropriate.
Heat stress often affects the gastrointestinal function of sows, resulting in decreased appetite and increased body weight loss. Therefore, feed formulations should be adjusted in time to improve feed palatability and nutrient concentrations so that sows can also reduce feed intake. Meet nutritional needs.
In the sow diet, 0.2% of hawthorn can be added to promote digestion, or 0.1% to 0.2% of baking soda can resist stress and increase appetite. Conditional farms can also be fed with green and juicy feeds to enhance their ability to resist heat stress. Sows with harder bowel movements can feed breastfeeding materials in advance 2 to 3 days before delivery, and put on laxatives such as sodium sulfate and artificial salt to prevent constipation.
5. Provide plenty of cool, clean drinking water
6. Adjust the feeding time, should feed the wet material. Summer sows in the summer to reduce feed intake, should adjust the sow feed time, adjusted to 6 am in the morning, adjusted to 6 pm in the afternoon, in order to improve the sow's intake the amount. Mix the feed wet to increase palatability.
7. Reduce various stress factors.
Sows show relatively strong expulsive reactions to unfamiliar individuals or bright colors. They usually require the keeper to wear a uniform uniform, do not easily change breeders, minimize stress stimuli, and reduce sows and pregnant sows. Number of columns, try to keep the inside and outside of the pig house quiet.
8. Do a good job of immunization and health care.
In summer, the temperature is high and there are many mosquitoes. In the late spring and early summer, JE vaccine should be well prepared. As the temperature rises, it is easy to cause blood protozoa, such as Eperythrozoon, Toxoplasma gondii, etc. through the spread of mosquitoes, etc. In order to prevent postpartum "triple syndrome" and piglet disease, etc., 1 week before and after sow delivery (ie, perinatal Period) to do good health care, intramuscular injection of constant Wei Kang 20 ml / time, can be added to the per ton feed Qing Kai Ling Ban Qing particles 500 grams or anti-virus 1 1000 grams + 70% amoxicillin 350 grams + Nuo (non-bitter enrofloxacin) 1000g purifies the sow disease and cuts the spread of disease from sows to piglets. Pay attention to the postpartum anti-inflammatory sows, a potent amoxicillin + Qingkailing + Houttuynia, continuous intramuscular injection for 3 days. When artificially assisted, the disinfection and sterilization of sows and operators must be performed in detail. The heatstroke sow was immediately moved to a cool and ventilated place to be rescued. The pig body was sprayed with cold water. At the same time, 5% glucose saline 200 ml to 500 ml was intravenously administered, and 10 ml to 20 ml of Fengqiang Star was intramuscularly injected. For irritated pigs, intramuscular injection of 2.5% chlorpromazine 20 ml.
9. Periodically deworming Each year in March to April, June to July, and September to October, it is best to periodically repel insects.
Summer sow rearing management techniques
Shanghai Hengfengqiang Animal Pharmaceutical Co., Ltd. Technical Department Ouyang Kunrong summer heat, high humidity weather easily cause sows heat stress, decreased collection, poor lactation performance, reduced conception rate, sow postpartum "triple syndrome" occurred Increased rates and problems such as constipation of sows have increased the difficulty of sow rearing and management and have reduced the economics of the farm.
