Embodiment 1

[0019] This experiment was carried out at the Tangrenshen Scientific Research Pig Farm in Hunan Province. There are 500 sows in the pig farm, and the pig house is semi-open, equipped with fans and wet curtains according to conventional breeding methods.

[0020] (1) Production and management of bedding bed

[0021] Four pig pens were selected, and bedding beds were made according to the designed formula according to the method of making bedding beds. At the same time, a control group and experimental groups were set up. The grouping conditions are shown in Table 1.

[0022] Table 1 Test grouping and the formulation situation of each group

[0023]

[0024] The prepared bedding bed will be flattened and used, and pregnant sows will be raised on it. Manage the sows according to the reported breeding and management methods for pregnant sows. The management of the bedding bed requires turning the bedding bed twice a week, with a depth of 40-50cm. Move the feces from the fece...

Abstract

The invention belongs to the technical field of agricultural farming, and particularly relates to biological padding suitable for a pig raising fermentation bed in south China. The biological padding is characterized by comprising the following components in parts by weight: 10-30 parts of 3-5cm straw, 40-20 parts of sawdust and 50 parts of chaff, and is prepared by the following steps of: preparing all components of the biological padding for raising pigs in a padding bed according to the formula amount, and sufficiently and uniformly stirring; adjusting the water content in the stirring process to keep the water content of the padding at 45% in a degree that the padding clusters when held by a hand and scatters when the hand opens; and spreading the prepared padding into a pig padding bed to obtain the biological padding, wherein the thickness of the biological padding for the growing nursery pigs is 90cm, and each pig occupies 0.6m<2> of an area of the biological padding; the thickness of the biological padding for the growing fattening pigs is 100cm, and each pig occupies 1.2m<2> of an area of the biological padding; and the thickness of the biological padding for sows is 110cm, and each sow occupies 2.0m<2> of an area of the biological padding. Through the invention, the scarcity of sawdust resources in the rice producing regions in south China is effectively solved, and a new utilization mode is provided for the pig raising padding of a fermentation bed.

Description

technical field [0001] The invention belongs to the technical field of pig raising, and in particular relates to a biological bedding suitable for fermentation beds in pig farms in southern China. Background technique [0002] Fermentation bed breeding can realize zero discharge of sewage in pig houses, has the advantages of no mosquitoes and flies, water saving, and pigs are not easy to get hoof disease. It has outstanding advantages in the suburbs of cities where water resources are scarce and environmental protection pressure is high. Fully mix sawdust, rice husk and fermentation agent, add water while mixing, control the humidity at about 60%, make a fermentation pile, and spread it on it to raise pigs after the fermentation is completed. The expired litter can be used to cultivate edible fungi and make organic fertilizers. Under reasonable arrangements, litter bed farming can become a green and environmentally friendly farming model with sustainable development. It is ...
