Sow color board feeding method

Abstract

The invention provides a sow color board feeding method. The method comprises the following contents: (1) according to a sow body shape scoring method, scoring fineness of each pregnant sow in a pig farm, and according to the fineness of each pregnant sow, distributing indicators in different colors; (2) according to the color of the indicator, determining feeding amount of each pregnant sow, to adjust the sow to standard figure of a corresponding stage. The method realizes refined single body shape and feeding management of sows in a pig farm from extensive group rearing, so that the sows keep good reproductive performance in a whole reproductive cycle.

Description

technical field [0001] The invention relates to the field of livestock breeding, in particular to a method for feeding sows with color cards. Background technique [0002] Reproductive performance of sows is greatly influenced by receptor type and body weight, but it has not been paid enough attention and is not understood. According to a British research report: the body weight of sows fed 4 kg per day was 22 kg less after delivery and weaning, and the back fat was 4.6 mm less. Physical exertion during the weaning period has a great impact on subsequent reproductive efficiency, including the following items: 1) The litter size of the next litter decreases; research by Deans Grore in the United Kingdom shows that the ratio of pre-breeding body weight to post-partum body weight is 10 kg less , the number of litters in the next litter will be reduced by 0.5; 2) Extend the distance between mating after weaning; 3) The durability period of sows is shortened, and the elimination...

Problems solved by technology

However, there are still quite a few farms where sow size varies greatly

One of the reasons is that with the improvement of sow breeds, the number of live piglets per litter is increasing year by year. For example, Dan sows can reach about 13 or 14 piglets per litter, and the lean meat rate of sows is getting higher and higher. The decline in feed nutrition and feed intake of high-yield sows during lactation led to insufficient weight loss of high-yield sows, which in turn affected the reproductive performance of high-yield sows in the next litter; the second reason, although there are differences in the industry However, in the actual pig production, most of the pig farmers have a low level of education and knowledge, which makes it difficult to apply various body shape management methods to the actual pig raising. Detect the body shape data, but do not know whether the detected data is correct, let alone how to use and adjust the sow body shape
