Embodiment 1

[0017] The test animals were 16 healthy Nubian black goats, aged 3 days, with an average body weight of 2.96±0.38kg. They were randomly divided into control group and test group, with 8 replicates in each group and 1 sheep in each replicate. Before weaning at the age of 2 months, the experimental group and the control group adopted the same feeding management, and the lambs sucked milk freely with the ewes. After weaning at the age of 2 months, the lambs were separated from their mothers and reared in metabolic cages. Feeding consists of Leymus chinensis (30%), alfalfa hay (30%), corn (20%), wheat bran (5%), soybean meal (10%), cotton meal (3%), additive premix (2%) ) composed of conventional full-mixed grains until 12 months of age. Feed twice a day at 09:00 and 17:00 respectively, and drink water freely. The test group was supplied with water from sucking teat drinking fountains, and the control group was supplied with water from duckbill drinking fountains. During the su...

Embodiment 2

[0019] The formal test was carried out when the goats in the test group and control group in Example 1 were reared by the above method and reached the age of 12 months. During the official test period, the goats in the control group and the test group were given red dye that was not absorbed by the gastrointestinal tract, mixed well, and all of them were free to drink water. Drinking fountain water supply. Routine feeding and management. After 6 consecutive days of experimentation, all the goats in the control group and the test group were bled and slaughtered before feeding in the morning of the 7th day. After opening the abdominal cavity, find the rumen, reticulum, omasum, abomasum, and small intestine, and ligate and separate them with cable ties, cut open each part of the gastrointestinal tract with a scalpel, and check the color of the contents of each part of the gastrointestinal tract with the naked eye. Observed. If it is red, it is recorded as "red", and if it is n...

Embodiment 3

[0025] The effect of supplementary feeding of enzyme preparations through esophageal groove reflex on the digestion and utilization rate of goat nutrients, the purpose of the third example is to test whether supplementary feeding of ordinary feed enzyme preparations without any rumen treatment through esophageal groove reflex can improve Digestive utilization of nutrients in meat goats.

[0026] Materials and Methods:

[0027] Enzyme preparation: select the feed compound enzyme preparation produced by a Shanghai Biotechnology Co., Ltd., containing protease, cellulase, etc., and the enzyme activity is 10000IU / g.

[0028] Experimental animals and feeding management:

[0029] Twelve 3-day-old healthy Nubian black goats with an average body weight of 2.32±0.28kg were selected as experimental animals. They were randomly divided into control group and test group, with 6 replicates in each group and 1 sheep in each replicate. Before weaning, the experimental group and the control ...

Abstract

The invention discloses a method for supplementing feeding of a meat goat growth-promoting agent through rumens. After meat goats are ablactated, water is supplied with sucking-type nipple drinkers, edible salt is dissolved in drinking water for supplementing feeding, and through long-term sucking action and intensified stimulation of the edible salt drinking water, oesophagus groove closing reflection of the meat goats can continue to adult years all the way. After the meat goats of two months are ablactated, the sucking-type nipple drinkers are always adopted for water supply, the edible salt is dissolved in the drinking water to supplement feeding, and through long-term sucking action and intensified stimulation of the edible salt drinking water, oesophagus groove closing reflection ofthe meat goats can continue all the way; within the time from ablactation to slaughtering, the compound growth-promoting agent is mixed and dissolved in the drinking water, and directly conveyed intoabomasums without passing through the rumens due to the oesophagus groove closing reflection, and finally reaches small intestines to exert effects, and therefore growth of the meat goats is promoted.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a method for feeding meat goats through the rumen with a growth-promoting agent. Background technique [0002] At present, raising sheep has the characteristics of less investment and quick results, and does not compete with others for food. It is the preferred project for the development of grain-saving animal husbandry. The fundamental reason why sheep can eat crude fiber such as weeds and straw as staple food is that compared with monogastric animals such as pigs and chickens, sheep have a compound stomach structure, and a large number of bacteria, protozoa, fungi, and archaea live in their rumen. Anaerobic microorganisms. After long-term evolution, a symbiotic relationship of interdependence and mutual restriction has been formed between rumen microorganisms and sheep. Sheep provide abundant food and a stable anaerobic environment for the growth and reproduction of...
