Problems solved by technology

[0011] The volume and mass of rice straw and eucalyptus are only 65-70kg / m 3 , the fluidity is poor, there may be a problem of clogging the pipe, and because the pig keeps arching the distributor, the distributor is deformed and the flow is more difficult

Embodiment

[0065] 1. Test materials and methods

[0066] In the same pig house, two pens with a ground space of 2.0mx3.54m were divided, and 12 Duroc x Landrace x Large White three-way hybrid pigs with an average weight of 38kg were divided into two groups, each group 6 heads, one group is the control group, and the other is the test group, adopting the same feeding and management method. Iron chains were hung in the circle of the control group as environmental enrichment; in addition to the iron chains hung in the test group, a cylindrical dispenser with compressed straw was installed vertically on the wall of the lying area, and the lower end of the dispenser was about 40 cm from the ground; the diameter of the compressed straw rod was 9 cm , length 38cm, weight 1.3kg.

[0067] 2. Observation indicators

[0068] (1) The posture and behavior of the pigs during the test; (2) The weight change of the pigs and the average amount of gnawing on the compressed straw during the test.

Abstract

The invention relates to the technical field of environment richness of pigsties, and provides a compressed straw bar for improving the environment richness of pigsties. The compressed straw bar is characterized by being prepared from the following components in percentage by weight: 75% to 85% of straw, 10% to 15% of molasses, 1% to 3% of edible salt, and 2% to 4% of wheat short, wherein a mixture of straw, molasses, edible salt and wheat short is compressed and formed. The invention also provides a preparation method of the compressed straw bar, and a distributor of the compressed straw bar corresponding to the compressed straw bar. The compressed straw bar has the beneficial effects that the compressed straw bar is designed according to the physiological property and behavior habit of the pig, the attraction force to the pig is large, the natural behavior expression of the pig is effectively promoted, and the occurrence of abnormal behaviors is reduced; the size is reduced to the 1 / 8-1 / 7 of original size, and the storage and transportation are convenient; the waste in the use process is little, the influence to the environment sanitation of the pigsty is little, and the replacement is simple and convenient; the distributor of the compressed straw bar has simple and reasonable structure, and is suitable for popularizing and applying.

Description

technical field [0001] The invention relates to the technical field of environmental richness in pig pens, in particular to a compressed straw stick for improving the environmental richness of pig pens, a preparation method and a dispenser. Background technique [0002] Intensive pig raising, most of the pig houses are made of concrete or light steel structure, the ground is hardened, and the limited activity space is surrounded by iron railings. Daily management is programmed and full-price compound feed is fed. There are very few things that pigs can come into contact with , The living environment is monotonous and poor. Just because pigs live in a poor and monotonous environment, their desire to seek effective stimulation cannot be normally satisfied, and various abnormal behaviors appear accordingly. For example, for sows raised in confined pens, as the number of litters increases, abnormal activities such as head shaking, pacing, dog sitting, chewing without food, and ...
