1. Benefits of refined feed fermentation Concentrate (here mainly referred to as corn, barley, sorghum, dried sweet potatoes, bran and other carbohydrate feeds) Fermentation is a feed modulation method and technology that should be promoted and promoted in pig industry and dairy industry . It mainly uses the microorganisms contained in the feed itself or additional yeast to ferment the feed under proper temperature, humidity and air conditions, decomposes the carbohydrates, produces lactic acid, acetic acid and ethanol, and becomes aromatic and slightly acidic. Fermented feed. After fermentation, the feed can improve the palatability, increase the digestibility and increase the vitamin B family, and can also increase the utilization of crude protein.
2. Methods for Fermentation of Precision Feeds There are two methods for fermentation of fine feeds.
(1) Direct Fermentation Method: First, the yeast or distiller's yeast should be diluted with warm water, and then diluted 0.5-1 kg of yeast or distiller's yeast and 150-200 kg should be added per 100 kg of ground mixture in the fermentation tank or concrete tank. °C - 40 °C warm water to fully mix, stand indoors, stirring once every half hour, after 6-9 hours can be completed by fermentation.
(2) Primer Fermentation: This method is actually the same as direct fermentation, and it only operates in two steps. First, dilute 0.5-1 kg of yeast or distiller's yeast with warm water, add 40-50 kg of warm water in a wooden bucket, and then pour the diluted yeast or distiller's yeast into it, plus 20 kg of carbohydrate-rich corn and barley. , dried sweet potato, sorghum or bran, etc., mix thoroughly, stand still, stir once every half hour, and make primers after 4-6 hours. In the second step, add 110-150 kg of warm water and 80 kg of mixture to the prepared feed. Stir well and mix well once every hour. Fermentation can be completed after 7-9 hours.
After fermentation, the concentrate feed has a good effect on the appetite, health, reproduction and feed utilization of pigs and cows, especially for pigs, and it is worth adopting.
