Key points of feeding tube for pregnant pigs in summer
First, pay attention to heat prevention and cooling
The suitable temperature for pregnant pigs is 15 ℃ ~ 18 ℃. Therefore, the heat prevention and cooling of pregnant pigs should be done well in summer to prevent heat stress. The measures are: all the doors and windows of the pig house are opened to make the air convection; to build an Arbor for pregnant pigs, cold water is often sprayed on pregnant pigs, and it is best to set up a bath to let pregnant pigs take a bath to cool down, so as to facilitate the normal growth and development of the fetus in the mother.
Second, adjust the feed in time
Heat often affects the appetite of pregnant pigs and reduces their food intake. Therefore, it is necessary to adjust the feed in time, increase the proportion of protein and energy feed, reduce the amount of coarse feed, feed more green succulent feed, and improve the nutrient concentration of feed, so that it can also meet the nutritional needs in the case of reduced feed intake.
Adjust the feeding time
It is hot at noon in summer, and pregnant pigs often lose their appetite. Therefore, feed every day must be early for breakfast, late for dinner, and more green fodder at noon. 80% of the feed should be fed in the morning and evening to reduce daytime intake and activity.
4. Ensuring feed quality
The quality of feed directly affects the growth and development of embryos. If moldy, rancidal, toxic or irritating feed is fed, it will cause abortion or death of embryos. Therefore, when matching feed, it is strictly forbidden to use moldy, toxic or irritating feed, but also to achieve Dangton feed, do not feed overnight spoiled feed.
V. do a good job in health and epidemic prevention
Summer is a very active season for the growth and reproduction of pathogenic microorganisms, and timely and effective health and epidemic prevention is the key to ensure the safety of pregnant pigs in summer. Therefore, it is necessary to frequently sweep the pigsty, do not allow feces and urine and sewage to accumulate, keep the enclosure clean and hygienic, and often wash the sink, food trough, disinfect the pigsty, raise utensils and so on. Once it is found that pregnant pigs do not eat, they should be treated in time.
VI. Expel mosquitoes and flies
At night, the pig house can light insect repellent incense or hang gauze-wrapped crystal trichlorfon to repel mosquitoes and flies; if possible, it can cover the whole yard with a gauze net at the open part of the pig house and at the door.

Duck nutritional metabolic disease-gout
Gout is an internal disease caused by protein metabolism disorders in ducks. The main pathological feature is accumulation of urate in joints, internal organs and other interstitial tissues. This disease occurs in the lack of green feed in the winter and early spring season. It can occur in ducks of different breeds and ages, and it is more common in young ducks clinically. Most of them are caused by the subjective and unilateral pursuit of weight gain speed by the breeder, ignoring the scientific allocation of feed and feeding protein feed with excessive content. After the duck is sick, it causes emaciation, loss of appetite and severe disease.
