Animal intake observation device and animal intake observation method

Abstract

The invention discloses an animal intake observation device and an animal intake observation method. The animal intake observation device comprises: an image acquisition unit, which is used for observing an animal intake situation; a mounting seat; a fixed assembly, which is connected with the mounting seat and worn on an animal body for fixing the position of the mounting seat; and an observationrod, which is connected with the mounting seat, wherein the tail end of the observation rod is connected with the image acquisition unit. The animal intake observation device and the animal intake observation method provided by the invention are applicable to grazing of livestock, such as yak, dairy cattle, horses and sheep; the animal intake observation device can move with movement of an animalin a grazing environment, and observes the intake condition of a grazing animal in real time; and the intake observation method can analyze parameters like the palatability of forage, the intake preferring index of an animal, the contribution degree of a plant to daily ration and the availability of the plant to comprehensively, truthfully and accurately reflect the intake habits of grazing livestock, so effective and reliable guidance is provided for subsequent grazing work.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to an observation device and an observation method for animal feeding. Background technique [0002] At present, most of the equipment for observing and recording animals, such as livestock feeding, is concentrated on house-raised livestock, and there are few recordings on the feeding situation of grazing livestock, even less for all-grazing livestock, such as yaks. [0003] In domestic animals, it has been possible to observe the feeding behavior of pigs through equipment such as the ACEMA48 system feed trough, and record the rumination behavior of cattle with a recorder. But the above-mentioned technology has the following disadvantages: 1. The former can only record the feeding situation in a certain feeding environment, such as pens; 2. Although the recorder can record the feeding behavior of grazing livestock, it can only record the feeding behavior based on audio. Eating time,...

Problems solved by technology

But the above-mentioned technology has the following disadvantages: 1. The former can only record the feeding situation in a certain feeding environment, such as pens; 2. Although the recorder can record the feeding behavior of grazing livestock, it can only record the feeding behavior based on audio. Eating time, total number of jaw movements, number of food intakes, etc.

The direct method is based on the measurement of forage grass, and samples are taken and weighed before and after grazing in the grazing area, but this method has certain defects: 1. The livestock should be enclosed in the area for grazing alone, which will stimulate the stress behavior of the livestock and affect the feeding behavior. 2. The forage feed intake of a single livestock cannot be measured; 3. Only the feed intake can be measured, but the data cannot reflect the livestock's preference for different forages

The indirect method is based on the determination of livestock, including feces collection, leak tube sampling and other methods combined with endogenous or exogenous indicators. 2. Leaky tube sampling involves animal welfare and experimental cost issues; 3. It cannot reflect the selective difference of livestock to native vegetation types, only the difference in the selection of nutrient elements, and the data cannot be predicted Regression Model of Grass Grazing in Grasslands
