[0002] Minbei Huazhu is a local pig breed in the northern mountainous area of ​​Fujian Province. It is a small-scale Huazhu. It is mainly formed by the local mountainous people after long-term selection and breeding based on factors such as living habits, high-energy feed, natural environment, and social economy. This kind of early-maturing and easy-to-fat, tender meat, delicious taste, strong adaptability, resistance to rough feeding, and strong disease resistance, is quite popular with the local people. However, due to its small size and slow growth, especially The farrowing rate is low, and the normal litter size of multiparous sows is 7-8 heads per litter. Currently, under the feeding conditions of green and roughage-based feeds in northern Fujian, and the breeding mode of free range, the current The average farrowing rate of northern Fujian Huazhu is 5-6 heads / litter, which is significantly lower than that of other multiparous sows (more than 10 heads / litter), which seriously restricts the development of Fujian Huayi pig industry
At present, there are no special formula feeds and feed additives for Fujian Huazhu, and there is no feed additive that can effectively improve the farrowing rate of sows in Fujian Huapi.

Embodiment 1

[0020] A method for preparing a feed additive for improving the farrowing rate of sows in northern Fujian, specifically comprising the following steps:

[0021] (1) Remove impurities: pick out the moldy, abnormal coix shells and impurities in the raw materials to obtain clean coix shells;

[0022] (2) Soak in rice vinegar: Add the coix husk after removing impurities into rice vinegar at a solid-to-liquid ratio of 1:0.2g / ml, soak for 5 hours at room temperature, and remove;

[0023] (3) Freezing: Put the coix shells soaked in rice vinegar in a freezer or freezer at minus 5°C for 24 hours, and then thaw naturally at room temperature for later use;

[0024] (4) Vinegar roasting: put the coix shells treated in step (3) into a frying pan, fry on medium heat for 5 minutes, and control the temperature at 150°C;

[0025] (5) Extraction: reflux the barley husk roasted with vinegar for 1.5 hours with 90% ethanol at a mass concentration 4 times its weight, collect the ethanol extract a,...

Abstract

The invention belongs to the technical field of sow feeds, and specifically relates to a feed additive capable of improving farrowing rate of sows of Minbei spotted pigs and a preparation method thereof. The feed additive capable of improving the farrowing rate of the sows of the Minbei spotted pigs is prepared from coix husk waste produced in coix planting and processing processes as a raw material by the following steps: soaking the raw material with rice vinegar; and then, carrying out freezing, stir-frying with vinegar, extracting, concentrating, spraying and so on so as to obtain the feedadditive. The prepared feed additive is added into daily ratio of pregnant and expectant sows of the Minbei spotted pigs at a feed weight ratio of 0.3-1.0%, and is uniformly stirred with the daily ratio so as to be ready for feeding; or the feed additive is added, in the form of a premix, into a basic daily ration formula for the sows of the Minbei spotted pigs, and subjected to granulation so asto be ready for feeding. Sows of the Minbei spotted pigs fed with feeds added with the feed additive have effectively improved farrowing rate. The average litter size of multiparous sows fed with thefeed additive can be up to 8-9 per litter, that is 2-3 more piglets per litter compared with control groups.
