What is the adaptation of a pig to temperature? What is the best temperature for pig growth?

The environmental temperature of the growth of fattening pigs refers to the temperature of the pig house, and the suitable temperature for the growth of fattening pigs is 15 a 22 The suitable temperature of pigs at different growth stages and weights is different, and the specific calculation formula is: t = 26 a 0 06w 。

t represents the optimal temperature required for growth, and w represents pig weight. For example, when the pig weighs 100 kg, the optimal temperature is t = 26 a 6 = 20 2 What is the effect of low temperature on piglets?

l) Low temperature has a great impact on the acquisition of maternal antibodies in newborn piglets. Colostrum eaten by newborn piglets after cold stress.

Less than 2 3 of the piglets at normal temperatures, maternal antibodies are obtained correspondingly reduced, and their immunity decreases, morbidity and mortality.

Increase. (2) Due to the incomplete development of the body thermoregulation function of the piglets themselves, the piglets are quite sensitive to temperature changes, especially to low temperatures. Therefore, low temperatures have a great impact on the growth and health of piglets.

3) In the low temperature environment, the piglet activity is restricted, the number of lactation is reduced, and the nutrient intake is insufficient, which directly affects the growth rate of piglets. (4) Low temperature can cause piglets digestive tract and respiratory tract.

The resistance is reduced, and diseases of the digestive tract and respiratory tract of piglets often occur. (5) Under low temperature conditions, the number of piglets crushed to death by sows due to fear of cold increases, and when the temperature is too low, piglets will also freeze to death. 3 What are the effects of low temperatures on fattening pigs?

The formula for calculating the critical minimum temperature of fattening pigs is e-195 a. ．065w 。

E stands for the critical minimum temperature and W stands for the live weight of the pig in kg.

Pigs are homeothermic animals, and when the outside temperature changes, pigs use their own regulation to maintain body temperature balance. The right temperature is very important for the growth and development of pigs. Generally, the most suitable temperature for newborn piglets is 34 35, the suitable temperature for 1 2 weeks after birth is 31 33, the suitable temperature for 3 4 weeks after birth is 28 30, the suitable temperature for the nursery stage after weaning is 24 27, the suitable temperature after coming out of the nursery is 20 23, and the suitable temperature for pigs weighing 40 kg is 18 22.

The optimum temperature for breeding boars is 17 21.

The optimal temperature for gestation sows is 18 21.

The optimal temperature for lactating sows is 20 22.

The optimum temperature for suckling piglets is 29 33.

The optimum temperature for nursery piglets is 22 25.

The optimum temperature for fattening pigs is 19 22.

In addition to knowing the temperature required by the pig herd at each stage, the manager should also have the corresponding conditions, such as ventilation and cooling equipment in summer, and heating and heating equipment in winter. In addition, breeders should also be required to register the temperature of their respective pig houses every day and keep records.

The suitable temperature for newborn piglets is between 32 and 35 degrees.

The optimal ambient temperature for newborn piglets is very important, and its comfort has a direct impact on the health and growth of piglets. In general, the optimum ambient temperature for newborn piglets should be between 32 and 35.

In the first few days after the piglet is born, the suitable ambient temperature should be higher, which can reach about 35. Because newborn piglets have a weak ability to regulate their body temperature, they need to rely on the external environment to maintain their body temperature, and too low or too high an ambient temperature will have a negative impact on their health. When the piglets are about 2 weeks old, it is advisable to gradually adjust the ambient temperature to about 28 to 30.

Maintaining a suitable environmental temperature is not only conducive to the growth and development of piglets, but also improves their immunity and reduces the occurrence of diseases.

Precautions for the maintenance of first-time piglets

On the day of the piglet's birth, it is recommended that the temperature of our incubator be kept at about 32, and from the next day, the temperature of the incubator will be adjusted according to the situation of the solid cavity plexus. As long as the piglets do not catch a cold, they can largely prevent the occurrence of yellow diarrhea in piglets. In addition, on the day of birth, we can also give it 2-3 ml of :

Liktaibao, which can also play a good role in preventing yellow diarrhea in piglets.

On the day of birth of piglets, we need Zheng Shen to be vaccinated with pseudorabies vaccine, and generally on the day of birth of piglets, pseudorabies vaccine intranasal vaccination is the mainstay. Since then, we have vaccinated the piglets every 7 days or so, such as swine fever, ring, foot-and-mouth disease, mycoplasma, etc., and these vaccines can be vaccinated according to the actual situation of our pig farm.

Here's the answer:

The most suitable Wenzhou age for newborn piglets is 34 35, the suitable temperature for 1 2 weeks after birth is 31 33, the suitable temperature for 3 4 weeks after birth is 28 30, and the suitable temperature for the post-weaning nursery stage is 24

The normal temperature of pigs is between 38 degrees and 39 degrees, when raising pigs, it is necessary to drive pigs to a separate pen for isolation when their body temperature is too high or too low, so as not to cause disease infection, and in the summer period, it is necessary to spray water mist into the pen to reduce the ambient temperature, and to provide sufficient drinking water for pigs to avoid thirst.
