Control method for automatically and accurately feeding pregnant sows

Abstract

The invention relates to a control method for automatically and accurately feeding pregnant sows. A combination of a feeding controller, computer client software, a storage hopper, a blanking motor and a trough is included, and electronic ear tags of the sows, an RFID antenna system, a wireless WIFI network, a proximity sensor, entrance and exit doors of a fully-mechanical channel and a linked control mechanism are also included. The control method comprises that 1) only one pregnant sow enters a feeding device at one time, and the ear tag is automatically identified; 2) according to the set feeding amount, the controller interacts with the proximity sensor to control blanking, quantitative ingestion and residual material for at least twice; and 3) a computer client queries the ingestion data of the controller, modifies the control parameters as the total feeding amount and the ending date of feeding. According to the method, individual electronic automatic identification, modularized computer control, sensor control and the feeding controller are combined, so that the sows can be accurately fed to an optimal state according to daily ration required by the physiological and labor nutrient.

Description

1. Technical field [0001] The patent of the present invention relates to the technical field of automatic feeding of livestock, in particular to a precise feeding control method for individual pregnant sows. 2. Background technology [0002] my country is a big country in the pig industry, and the number of commercial pigs slaughtered each year is basically more than 600 million, ranking first in the world. The number of reproductive sows is basically stable, about 49 million, accounting for about 11% of the total number of live pigs. This means that in our country, more breeding sows are needed to ensure the number of marketable pigs. Specifically, it concerns the level of productivity of breeding sows. According to the sow productivity industry basic report provided by Agri-stats in 2010, in the European countries with high sow productivity, such as the Netherlands, Denmark, Ireland, France, etc., the annual litter size of a breeding sow is 2.3~ Between 2.5, the number o...

Problems solved by technology

[0010] Technical problem: the present invention aims at the failure in the prior art to preset the ration feeding amount of individual sows according to the physiological and production goals of individual pregnant sows, nor can it be based on the actual amount of food that can be eaten (may be less than the preset Quantity), automatic control so that there is no defect in feed trough leftover feed, provides an automatic control method based on individual identification of sows and precise feeding of rations, and develops a set of ear tags for individual pigs to wear, Method and equipment for multiple feeding under effective identification and total amount control and no leftover material control
