Embodiment 1

[0028] Embodiment 1, taking four feed troughs as an example, four feed observation windows 6 are arranged on the conjoined feed trough cover 3 corresponding to the position of the feed trough 2, and each feed observation window 6 is provided with 8 through holes with a diameter of 40 mm. Hole 7. During use, put different feeds in the feed buckets in each conjoined feed trough 2, and let a sheep enter the sheep activity area A in the fence 1 from the fence door 15, and at this time the conjoined feed trough cover 3 is closed state, let the sheep observe the feed and smell the smell of the feed through the circular through hole 7 on the feed observation window 6 for 2 minutes, then lift the upper and lower door 18 to isolate the sheep from the combined feed tank 2; then open the combined feed tank cover 3 (eg figure 1 The shown conjoined feed trough cover is positioned at the state of upturning 90 degree angle), then puts down the upper and lower door 18, so that sheep can appr...

Embodiment 2

[0029] Embodiment 2, and embodiment 1 steps are the same, just observe feed time and change to 3 minutes; Repeat above-mentioned observation-feeding process 3 times to each sheep, each experiment provides 3 chances of choosing food to measure sheep feed palatability .

Embodiment 3

[0030] Embodiment 3, the steps are the same as in Embodiment 1, except that the free feeding time is changed to 5 minutes. Repeat the above observation-feeding process 4 times for each sheep, and each experiment provides 4 opportunities to choose food to determine the palatability of sheep feed.

Abstract

The invention discloses a sheep feed palatability measuring system and aims at solving the technical problems of long measurement time, a large quantity of feed, animal houses with large area, few chances for sheep for selecting feed for multiple times, incapability of dynamically recording the feeding behaviors of the sheep and the like in the prior art. The system comprises at least two conjoined feed troughs, conjoined feed trough covers, upper and lower sliding door devices and measuring devices, wherein the conjoined feed trough covers are arranged on the conjoined feed troughs; feed observing windows are arranged on the conjoined feed trough covers; through holes are formed in the feed observing windows; each measuring device comprises a weighing sensor, a laser correlation emitter and a camera. The sheep feed palatability measuring system is capable of accurately measuring time of the sheep for selecting the feed and accurately measuring feeding time; the measurement time of each sheep is short, and the quantity of the required feed is small; the sheep can be effectively separated from the feed troughs, the manual interference on the sheep is lowered, and the chance for the sheep for selecting the feed can be provided for multiple times; the feeding behaviors of the sheep can be recorded dynamically, thereby making relatively accurate evaluation on the palatability.

Description

technical field [0001] The invention relates to the research fields of animal nutrition, animal welfare, feed science and pasture science, in particular to a set of system for measuring the palatability of sheep feed. Background technique [0002] Feed palatability is one of the important factors affecting animal feed intake. Improving feed palatability can increase animal feed intake within a certain range and increase productivity. Therefore, the determination of feed palatability is a must-do item when developing new feed and researching forage formula. However, the traditional palatability research method has the following disadvantages: 1. The measurement time is long: the traditional research method is mainly based on ad libitum feeding, and the measurement time is at least 96 hours; 2. The amount of feed required for the determination is large: the traditional research method uses The average daily feed intake is used as a criterion for judging palatability, so the a...
