Sows don't want to eat in summer. What's the solution? The use of "two objects" in the kitchen has achieved good results.

We often say that "big pigs are afraid of heat and little pigs are afraid of cold" because the sweat glands of pigs are underdeveloped, the fat on the body surface of sows is thick, and the body's heat dissipation ability is poor. When encountering high temperature weather, the heat production and heat dissipation in sows are unbalanced, and the excess heat can not be distributed in sows, which will cause a series of physiological reactions in sows, and this reaction is what we often call "heat stress".

One of the most intuitive clinical manifestations of sow heat stress is the decrease of appetite and feed intake.

The decrease of sow's food intake will produce a series of side effects, such as dystocia, more sows with long labor, more stillbirths, more sows with postpartum lochia and endometritis, insufficient nutritional intake of suckling piglets, increased incidence and mortality of diarrhea, and excessive weight loss during lactation, which will affect estrus after weaning, reduce the number of sows' ovulation and affect the number of sows' litter.

Therefore, the heat stress of raising pigs in summer is a problem that must be solved.

Of course, the most effective way to prevent and control heat stress is to provide a comfortable environment for sows. Theoretically, if the temperature of the pigsty is controlled at 30℃, sows will not be harmed by heat stress. However, the hardware facilities of most pig farms are difficult to reach this level, and they still rely on drugs to prevent and control heat stress in clinic. For example, Pogostemon cablin, Borneolum Syntheticum, Radix Bupleuri, Herba Menthae and other traditional Chinese medicines can play a very good role in preventing and treating heat stress.

In addition to giving drugs to sows to improve heat stress and increase appetite, there are actually two things in our kitchen that can improve heat stress, increase appetite and increase food intake.

1, vinegar

Vinegar is an essential condiment for every family, which is rich in amino acids, lactic acid, various minerals, various organic acids, titanic acid, ligustrazine and other nutrients.

Traditional Chinese medicine believes that vinegar is sour, warm and non-toxic, and has the effects of removing blood stasis, stopping bleeding, detoxifying and killing insects when it enters the liver and stomach meridians.

"Herbal Supplement" records that vinegar can "break blood circulation, eliminate symptoms and eliminate accumulation, promote digestion and eliminate accumulation, kill malice, break stagnation, and cause sour water and phlegm in the heart.

"

Clinically, if sows have poor appetite and don't want to eat, vinegar can be sprinkled in feed to induce food, or diluted in water for sows to drink or take orally, which can promote digestion and enhance appetite.

2. Sodium bicarbonate

Baking soda is also one of the common kitchen supplies in the family. Its main component is sodium bicarbonate, which is an alkaline substance.

In summer, when sows are affected by heat stress, they will speed up their breathing to dissipate heat. After breathing is accelerated, the gas exchange in the lungs will be incomplete and the metabolic acid in the body will increase. Baking soda, as an alkaline substance, can neutralize excess acid, stabilize the pH value of body fluids and ensure the normal metabolism of cells.

In addition, the sodium loss of pigs is serious after heat stress, and baking soda can supplement the lost sodium.

Baking soda can be added to feed at the ratio of 0.3% to prevent heat stress in pigs. If vitamin C is added, the effect will be better.

If pigs have been injured by heat stress, 0.2% baking soda and 0.03% vitamins can be added to drinking water to treat heat stress.

The problem of heat stress has been improved, and the appetite and feed intake of pigs can naturally recover.
