What suitable environment are needed for fattening pigs

Mainly ventilation and temperature.

How to manage fattening pigs to be healthier? "In response to this issue, I would like to share my personal views with you.

Fattening pigs, from birth to slaughter, need to go through three stages, one is the piglet feeding stage; the second is the shelf pig feeding stage; The third is the fattening pig feeding stage. Among these three feeding stages, there are two transitions, one is the transition stage from the piglet stage to the shelf pig, and the other is the transition stage from the shelf pig to the fattening pig.

In the whole fattening pig feeding stage, how to smoothly achieve two transitions, that is, piglets to shelf pigs, and then to fattening pigs?

In this stage, three measures need to be taken to do a good job in the transition management of the piglet to the shelf pig stage: first, reasonable grouping, the main criterion for grouping is the weight of the piglet, and the weight of the congratulatory is the same size in a group. Of course, it is also necessary to distinguish according to the strength of the physique to avoid grabbing and eating badly, which will affect the eating of pigs with weak physique; The second is to choose feed.

According to the physique of the piglet, the feed to be fed should be selected. Mainly young green feed, with an appropriate amount of salt and mineral feed; The third is the feeding method. Feeding should be gradual, concentrate from more to less, green roughage from less to more.

The purpose of such a feeding method is to train the piglets to slowly adapt to the green roughage and successfully transition to the shelf pig stage.

The transition management from the shelf pig to the fattening pig stage has just entered the shelf pig stage, and the green roughage should be the mainstay. The amount should be gradually increased and gradually increased, so that the shelf pigs can transition to the stage of a large amount of green roughage. However, in order to avoid the shelf pig stage being too long, concentrate should be mixed in the late stage of the shelf pig and slowly increase to ensure a smooth transition to the fattening stage.

From the above, it can be seen that the successful realization of fattening pigs"Two transitions"The combination of feed feeding is very important, and each transition needs to be gradual and not rushed. In addition, it should be noted that piglets and shelf pigs are particularly prone to disease, and more attention should be paid to the prevention of diseases.

It should be noted that when feeding, we must ensure that the feed is clean and hygienic, and the lead should also be sprayed with some disinfectant in the environment where they live, and the quality of the feed should also be improved.

The first should pay attention to the feeding density and grouping, the second should do a good job in disease prevention and control, the third should pay attention to feeding methods, the fourth should pay attention to the feeding environment, and the fifth should be castrated.

Be sure to add some nutrients to the feed, to carry out a reasonable match of nutrition, to add some vitamins, to clean the pig house regularly, to ventilate regularly.

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. Newborn piglets under cold stress eat less than 2 3 of piglets at normal temperatures, and maternal antibodies are reduced accordingly, their immunity decreases, and 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 temperature will have a great impact on the growth and health of the late plexus in the piglet hall. (3) In the low temperature environment, the activity of piglets 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 the resistance of piglets' digestive tract and respiratory tract to decrease, and piglet digestive tract, respiratory tract and other diseases 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-19

5 a. ．065w 。E stands for the critical minimum temperature and W stands for the live weight of the pig in kg.

Pork is the most common meat products in our daily life, basically you can eat pork every day, so with the expansion of the pork market, the scope of the breeding industry has gradually become one of the main rural breeding projects in China, breeding is for the meat of the body, so the management of pigs in the fattening period is very critical, because the fattening period is the key period of pig fattening, the following will introduce you to the key points of management of pigs in the fattening period, let's take a look.

1.Feeding management.

Pigs in the fattening period of management is very critical, because this stage is the strongest pig growth and development ability of the time, so the demand for feed will be greatly increased, so to give full feed to ensure that fattening pigs fattening needs nutrients, at the same time to ensure that drinking water is abundant, drinking water should be clean and zero pollution, to avoid heavy metal substances in drinking water, if there are heavy metals in drinking water, it will make the nutrient absorption of fattening pigs blocked, malnutrition, so that it can not increase fat normally and other conditions, In more serious cases, it may also cause fattening pigs to die of internal organ poisoning.

2.Environmental management.

Changes in the natural environment will produce a variety of different reactions to fattening pigs, fattening pigs are very sensitive to changes in the natural environment, we must ensure that the pigsty can be properly ventilated and ventilated, to avoid too many harmful substances in the pigsty, and reduce the probability of respiratory diseases caused by fattening pigs. At the same time, it can reduce the prevalence of infectious diseases that use gas as a vector. Control the sunlight exposure of the pigsty, the excessively dark natural environment is an important condition for the production of germs, but too strong sunlight will directly affect the rest of the fattening pigs, so in the environmental management not only to do a good job in environmental sanitation, but also need to control the radiation and ventilation of the pigsty.

3.Temperature management.

The development temperature of fattening pigs can not be too high or too low, the development temperature suitable for fattening pigs is around 20 degrees, and the temperature is always kept in the range of 18-22 degrees, which can accelerate the speed of pig fattening, improve the conversion rate of feed, if the temperature is too low, fattening pigs need to spend a lot of nutrients on maintaining their own body temperature, the fattening pig's fat gain and growth and development are very bad, and the resistance of fattening pigs will also be reduced.

In addition, when breeding pigs, it is necessary to regularly observe the growth of each fattening pig in the pigsty, and to record the work, record the weight gain of the fattening pigs, the amount of meals, the activity status and whether it is healthy.

We must pay attention to Ji Huidu's suitable feed Bijian matching, should be vaccinated in time, need to kill insects in time, and should also clean up all the feces inside the venue in time, and also take the pigs for walking.

The environment is required to be particularly high and strict, it must be particularly clean, and the water to drink should also be high-quality water, in the process of growth, do not have too much sunlight, and the temperature of the letter bird should not be too low, but also pay attention to keeping warm. Slippery hunger.

The specific requirements should be Li slag is to supplement more nutrition, and not only to eat pig food, but also to quietly manage the pigs, of course, also need to do a good job of ventilation treatment, more to observe the destruction of pigs, what is wrong every day, timely ** these diseases.

To provide sufficient feed in a timely manner, we should pay attention to the composition of the feed, supplement the nutrients in time, and ensure a good growth environment for the feast, ventilate regularly, and grasp the density of captivity.

When the pig is in the fattening period, the requirements are, 1. Prepare a dry pigsty, 2. Excellent feed to rent the front, 3. Clean water, 4. Keep warm, 5. Make Qin Sheng use vaccines, prevent and control pig diseases, and so on.

The optimum temperature for the growth of fattening pigs is: before the weight of 60 kg 18 22; 60 90 kg 17 21 ; More than 90 kg 16 20, the relative humidity in the general house is 50% 75%.

How to do the weaning trough of piglets correctly?

The first point is to grasp the timing of the trough, the trough time is generally 5 days after the birth of the suckling pig, the most important thing is to master the lactation time of the sow, to start feeding before the sow is about to release milk.

The second point is to choose trough tools, according to the habits of pigs, wooden troughs are best, they like to gnaw. Secondly, you can choose iron or rubber.

The third point is to grasp psychology. After putting in the trough and sprinkling the trough material, the piglet goes back to the trough to gnaw, and occasionally eats the feed into the mouth, but if it is placed for too long, the piglet will lose interest in the trough, and will arch the material out of the trough, resulting in waste, we all know that the trough material is very expensive. Over time, the piglets will also excrete on the trough, and eventually the trough becomes a toilet and a source of infection.

How to solve it, then we put the trough and feed in at the best time, and take it out when the sow starts to suckle, so that the repeated trough is fast, and it can also reduce waste and save costs.

According to scientific statistics, the optimal temperature for fattening pigs: 17 22. Suitable temperature: 15 23 .
