Technical Field

The invention relates to the technical field of gosling feed, in particular to a starter of meat goose starter feed and a preparation method thereof.

Background

According to the growth cycle of the goose, the gosling which just hatched from the eggshell for 1-7 days is called the opening stage of the goose. At the moment, the goose has weak adaptability to the outside, and various diseases are easy to occur due to incomplete intestinal development and poor temperature regulation and disease resistance of the gosling, so that the problems of reduced growth performance, increased mortality rate and the like of the gosling are caused, and the breeding cost is increased. Therefore, in order to improve the growth performance of the meat geese in the starter stage, attention is paid to preventing stress reaction in the feeding management, and besides, the meat geese in the starter stage are provided with the feed which is balanced in nutrition and easy to digest, so that the elimination rate and the feeding cost of the goslings in the starter stage are reduced, and the economic benefit of cultivation is improved.

Because the digestive system of the gosling in the starter is not developed completely, the conversion and absorption capacity of the nutritional ingredients in the feed is poor, in order to better promote the absorption of the gosling in the starter on the nutritional ingredients, the feed needs to be fermented, substances which are not easy to be absorbed and utilized by the gosling in the feed can be converted into high-energy nutritional ingredients which are easy to absorb through the fermentation, the digestive absorption of the gosling in the starter is facilitated, and the effects of promoting the development of the body and enhancing the immunity of the body are achieved.

Most of the existing fermentation treatment modes are integral fermentation feed or added with a leavening agent, and although the fermented feed and the leavening agent of goslings exist in the market at present, the fermented feed and the leavening agent specially used for the goslings in the starter period are less, in particular to the leavening agent of the feed of the goslings in the starter period. The feeding dosage of the whole fermented feed is large, so that the cost is overhigh, and the breeding cost of farmers is directly increased. Chinese patent CN102524538B discloses a feed leaven for promoting goose growth and liver development, which comprises the following components in percentage by weight: 0.1-0.15% of bacillus, 0.1-0.2% of microzyme, 0.3-0.4% of lactic acid bacteria, 0.2-0.3% of butyric acid bacteria, 0.05-0.1% of filamentous fungi, 0.5-2% of auxiliary agent and the balance of carrier.
