Sheep digestion and metabolism cage capable of automatic weighing

Abstract

The invention relates to the technical field of sheep nutrition research, belongs to a testing device of sheep digestion and metabolism, and particularly relates to a sheep digestion and metabolism cage capable of automatic weighing. A top hurdle is arranged at the top of the cage; side steel plates are arranged at the two sides of the cage; a trough door plate is arranged in the front of the cage; the rear part of the cage is provided with a rear board; a trough and an automatic water trough cavity are arranged side by side at the front end of the bottom of the cage; and the rear end of the bottom is provided with a manure leaking floor. The bottom of the cage is provided with a level-adjustable loadometer foot bench; a quantitative feeding machine fixedly connected to the outside is arranged vertically above the trough; a discharging pipe of the quantitative feeding machine is provided with a sheep number recognizing sensor; an automatic water trough and a water pipe, fixedly connected to the outside, are arranged vertically above the automatic water trough cavity; and the water pipe is provided with a flowmeter. In the cage, a metering cup of the quantitative feeding machine has the maximum capacity of 10kg, and the feeding accuracy can reach 10g. The cage has the maximum weighing of 200kg, and the weighing accuracy can reach 50g.

Description

technical field [0001] The invention relates to the technical field of sheep nutrition research, and belongs to a test device for sheep digestion and metabolism, in particular to an automatic scale that can be used for different stages, different body sizes and production purposes (milk or meat) and fistula sheep digestion and metabolism tests Heavy Sheep Digestive and Metabolic Cages. Background technique [0002] At present, researchers often use in vivo method (InVivo), semi-in vivo method (also known as nylon bag method, InSacco) and in vitro method (InVitro) to study the laws of sheep's digestion and metabolism of nutrients. In vivo methods usually use digestive and metabolic cages to collect and sample the digestive metabolites of sheep; semi-in vivo and in vitro methods usually use rumen fistula to collect gastrointestinal contents and infuse nutrients in sheep, which usually cannot be carried out in digestive and metabolic cages. conduct.

AI Technical Summary

Problems solved by technology

[0003] Traditional sheep digestion and metabolism cages have simple functions, and only have the functions of feeding and drinking in a single cage. When receiving feces and urine, they are mixed and it is difficult to completely separate them.

The collection of feces and urine by installing feces bags and urine bags on test sheep can only be used for rams, not for ewes

Therefore, the traditional sheep digestion and metabolism cage has a small range of uses, and it is difficult to completely separate and collect feces and urine, and the experimental effect is poor.

[0004] Secondly, traditional sheep digestion and metabolism cages do not have facilities such as automatic identification of sheep numbers, automatic feed feeding, automatic metering, automatic weighing, and real-time data collection and transmission. They cannot automatically record the weight and feed intake of sheep during the test in real time And other data changes, the accuracy and reliability of experimental data is difficult to guarantee

[0005] Moreover, a large amount of manpower is required during the test, which is labor-intensive and time-consuming, and the measurement is inaccurate, not timely, and the efficiency is low
