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 normal temperature of a pig is 38.

Normal body temperature in pigs.

It is 38, and the body temperature of pigs of different ages is also different. The body temperature of the newborn pig is 39, the body temperature of the suckling piglet is, the body temperature of the middle pig is 39, the body temperature of the fat pig is, the body temperature of the pregnant sow is, and the body temperature of the boar is. In general, the normal body temperature of pigs in the evening is higher than that in the morning.

Pig breeding methods

1. Closed pig raising

At present, more than 90% of pig farms choose this method, feeding full price feed throughout the whole process and implementing strict biosecurity.

Prevention and control strategy, fast growth, low feed-to-meat ratio, 6 months can be slaughtered.

2. Pig breeding by local method

The whole process is free-range, from birth does not feed the full price, the food is mainly grain, green feed, no vaccination, no antibiotics, slow growth rate, high feed to meat ratio, more than 10 months to slaughter.

3. Mixed pig breeding

In the early stage, the closed pig raising, and the last two months of local pig raising. The growth rate and feed-to-meat ratio are between 1 and 2, and the slaughter time is mostly more than 8 months.

4. No antibiotic pigs

In recent years, the main feature of pig breeding methods is that antibiotics are not used in health care and ** links, and other pig breeding methods are similar to closed pig farming. Due to the reduction of breeding efficiency, the production cost is increased.

If you can't achieve premium sales, you will lose money, so not many people choose this method to raise pigs.

5. Pig raising in swill

Mainly use the swill of hotels, canteens, and restaurants to feed pigs, and due to the low cost, it has attracted a group of bold people to raise pigs with swill. But in the African swine fever epidemic.

Since it happened, the number of people who use this method to raise pigs has decreased significantly.

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

Optimal temperature range for <> boars: 17-21. Pregnant sows are more suitable for the temperature of the nest range:

18-21℃。Optimal temperature for lactating sows: 20-22.

The most suitable temperature for suckling piglets: 29-33. Nursery piglets are more suitable for temperature bending:

22-25℃。The most suitable temperature for fattening pigs is 19-22.

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.

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.
