A feeding device for experimental pigs

Abstract

The invention provides a feeding device for experimental pigs, which includes a quantitative feeder and a trough, and a movable trough cover is arranged above the trough, and the movable trough cover is connected to a driving mechanism. When the driving mechanism drives the movable trough cover When it is at the left limit position, the movable tank cover can just cover the first tank, and the second tank is open; when the driving mechanism drives the movable tank cover to the right limit position, the movable tank cover can just cover the food tank 2. At this time, the trough is open; a weighing device is provided outside the trough; the present invention not only solves the time-consuming and labor-intensive technical problems of separating pigs into pens and feeding in separate pens, but also reduces the risk of pigs caused by manual penning. Stress, reducing the fighting injuries of multiple mixed pens, is conducive to distinguishing and reducing the specificity of individual differences, and can also realize precise feeding of experimental pigs without affecting the growth of pigs, which is conducive to individualization Intensive breeding, especially the phased refined nutrition research.

Description

A feeding device for experimental pigs technical field The invention belongs to the field of pig experimental equipment, in particular to a kind of feeding device for experimental pigs. Background technique Carrying out precision feeding to pigs is the mainstream direction of future development in the field of pig raising, and in the process of precision feeding, it is necessary to Minimized factors include precise control of feeding amounts. Studies have shown that the existing precision feeding mainly consists of staged feeding and feeding. mode, in the nursery pig stage (body weight 4-21Kg), it can be fed in four stages, and in the fattening pig stage (body weight greater than 21Kg), Feeding can be carried out in five stages, and the amount of feed is put in each stage according to the nutritional needs. However, most of the existing feeding equipment There are the following problems: the feed in the same tank cannot contain different feeds separately; in the sa...

Problems solved by technology

However, most of the existing feeding equipment has the following problems: the feed in the same trough cannot be separately filled with different materials; in the same batch of pigs, there are individual differences, so that each time the pigs eat, they cannot eat according to their own weight If the corresponding feed is weighed and separated according to different weights every day, one needs manual separation, which is time-consuming and laborious, and the other is separated by automatic separation equipment (mainly imported equipment), but its cost is high and the separation effect is not ideal; Especially in scientific research or testing, there are often different nutritional levels at the boundaries. If batch weighing is carried out, there will be disadvantages such as large stress on pigs and large deviations in experimental data. Usually, it can only be determined by later statistics. analysis to process data

Although this kind of special cage is convenient for carrying out experiments on pigs, it is particularly easy to affect the activity and growth of pigs, which will lead to a large difference between the experimental results and the growth of normal pigs
