A farrowing house that meets the different environmental needs of sows and piglets and achieves precise ventilation

Abstract

The invention discloses a parturition house which meets different environmental demands of sows and piglets and realizes accurate ventilation. The parturition house comprises a parturition house body,a ventilation system, a head cooling system and a neck cooling system; the parturition house body is internally provided with a ventilation chamber and underground air ducts, wherein the ventilationchamber is formed in the end part of the parturition house body and provided with an air inlet, a wet curtain is arranged at the air inlet to form a primary cooling device of the parturition house, and the underground air ducts are formed below each passage and communicated with the ventilation chamber and form a secondary cooling device of the parturition house; fans are arranged on the roof, andbranch pipes of the underground air ducts are gradually increased from the front side to the rear side in the house body for obstetric tables and directly face the heads of the sows; meanwhile, watercooling is adopted for the necks of the sows. Through comprehensive utilization of evaporation, ground source heat, convection and the conduction heat exchange principle, accurate temperature reduction for the sows in summer is achieved, and cold stress of the piglets is avoided by utilizing the underground air ducts for preheating air entering the house and keeping the temperature of the air constant in winter.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding facilities and equipment, in particular to a farrowing house that meets the different environmental needs of sows and piglets and realizes precise ventilation. Background technique [0002] China has a vast territory, and most areas are hot in summer and cold in winter. Pigs are endothermic animals, and their own sweat glands are underdeveloped, their own temperature regulation mechanism is low, and the ambient temperature is too high or too low, which will adversely affect the production and growth of pigs. Therefore, it is necessary to take measures to reduce the ambient temperature in hot summer to reduce heat stress, and to take measures to increase the ambient temperature in winter to reduce cold stress, so as to reduce the negative impact of excessively high or low ambient temperature on pig production and growth. [0003] The specific environmental temperature adjust...
