Problems solved by technology

The actual production in this field proves that in winter, if the temperature is lower than 25°C, the piglets are prone to loose stools, and the piglets will not eat milk, resulting in mastitis or clogged teats, which will affect the lactation ability of the sows, increa

Embodiment 1

[0012] The present invention firstly relates to providing a method and method for improving the survival rate of sows and maintaining a suitable environment temperature for sows in labor rooms in summer. The basic basis is that the long-term production practice in this field has proved that when the temperature is higher than 25°C, the heat stress on the sow is greater, which increases the embryonic death and delivery time of the sow, and affects the subsequent reproductive ability of the sow. For this reason, in summer, the present invention adopts self-energy water curtain type air conditioner to cool pig house, if the burden of water curtain type air conditioner is too heavy, it can be supplemented with drip type cooling to control the indoor temperature to maintain at 23-25°C. During this period, there were 210 sows waiting to give birth, with a total of 2,541 litters, 2,478 live litters, and 63 stillborns. The stillbirth rate accounted for 2% of the total litters. 2,413 we...

Embodiment 2

[0019] The invention also relates to providing a method and method for improving the survival rate of sows in winter and maintaining a suitable environment temperature for sows in labor rooms. The main basis is that the key in winter is to maintain the temperature of the sow and the birth temperature of the piglets; the suitable temperature for the sow is 25°C and the piglets should be born at 30°C. The actual production in this field has proved that if the temperature in the house is lower than 25°C, the piglets are prone to loose stools, and the piglets do not eat milk, resulting in sow mastitis or clogged teats, affecting the lactation ability of the sows, increasing the mortality rate of piglets, and reducing the weaning weight. If the temperature in the house is higher than 25°C, the feed intake of sows will be reduced by 10%-30%, which will directly affect the amount of lactation and cause more piglets to starve to death. If the temperature is not well controlled, piglet...

Abstract

The invention discloses delivery room temperature capable of increasing sow farrowing survival rate and a control method of the delivery room temperature. An intelligent water-curtain-type air conditioner is used to cool big environment of a hoggery delivery room to enable environmental temperature of the delivery room to reach 23-25 DEG C in summer; in winter, a heating radiator is used for temperature of the big environment of the delivery room to enable the temperature to be controlled at 25-27 DEG C, and a heat-insulating lamp and an electric heating plate are used for small environment of piglets. Compared with the prior art, the delivery room temperature and the control method have the advantages that according to different weather characteristics of summer and winter, an effective hoggery environment temperature control method is utilized to control the delivery room environment temperature to enable the same to reach a constant standard, so that cold-heat stress reaction of the piglets is reduced, and the survival rate of the piglets delivered by a sow in the delivery room is remarkably increased. The control method is simple and convenient in operation, easy to control and low in cost, high economic benefit is obtained with low investment, and an effective path is provided for improving production efficiency of an intensive pig farm.

Description

technical field [0001] The invention relates to an ambient temperature in the field of animal husbandry and a control method thereof, in particular to an ambient temperature of a pig house and a control method thereof for achieving the optimal temperature of a farrowing sow and newborn piglets in a farrowing room and improving the survival rate of piglets born by the sow. Background technique [0002] The ambient temperature of farrowing rooms in intensive pig farms is very important, because farrowing sows and primiparous piglets are very sensitive to temperature, and their respective suitable temperatures are different. Excessively high temperature will cause heat stress in sows and make pigs Reproduction and breeding are affected, and it will induce the occurrence and prevalence of various diseases in piglets; too low temperature will also lead to a decline in sow production performance, affect the survival rate of piglets, and seriously affect the safety and efficient pro...
