Embodiment 1
[0017] A method for fermenting pig blood protein feed includes the following steps:
[0018] (1) According to the ratio of bran mixture: fresh pig blood: blood meal=1:1:0.15, mix the materials evenly;
[0019] (2) Mix according to the ratio of Flavourella family No. 6 strain: Flavourium family No. 7 strain: Lactobacillus acidophilus PB1=3:3:4 to obtain the starter;
[0020] (3) Add the starter obtained in step (2) and the material obtained in step (2) at 0.2% of the total amount and mix them evenly, then add water and stir evenly with a mixer. The stirring time is 8 minutes, and the moisture content is controlled at 65%;
[0021] (4) Put the material obtained in step (3) into the container and exhaust the air, cover it with plastic film for sealed fermentation, the fermentation temperature is 35℃, the relative humidity is 92%, and after 2 days of fermentation, the second heating fermentation is carried out. The fermentation temperature is 50°C, the relative humidity is 92%, and the fe...

Abstract
The invention discloses a fermenting method for a porcine haemoglobin feed. The fermenting method comprises the following steps: (1) uniformly mixing bran mixture, fresh porcine blood and dried blood in a ratio of 1:1:0.15 or 1:1:0.15; (2) uniformly mixing a yellow mould family strain No.6, a yellow mould family strain No.7 and a lactobacillus acidophilus PB1 in a ratio of 3:3:4, thus obtaining a leavening agent; (3) adding the leavening agent obtained in the step (2) accounting for 0.1-0.2% of the total material weight, uniformly mixing with the material obtained in the step (1), then adding water, and uniformly stirring; and (4) putting the material obtained in the step (3) into a container, then exhausting the air, covering with a plastic film and carrying out sealed fermentation, and then carrying out spray drying, thus obtaining the porcine haemoglobin feed. According to the fermenting method disclosed by the invention, the soluble substances can be increased by 45.2% and the digestibility can be improved by 25-30%, protein absorption and utilization rate is high, palatability is good, and the developed porcine haemoglobin feed is detected to contain no aflatoxin B1 and is safe and reliable; meanwhile, the porcine haemoglobin feed has the advantages of rich raw material sources, low price, simple production method and long storage life and has very broad market prospect.
Description
Technical field [0001] The invention belongs to the field of feed, and specifically relates to a method for fermenting pig blood protein feed. Background technique [0002] Pig blood contains high protein. The feed produced by fermenting waste blood from animal slaughter with starter is a kind of nutrient-rich animal protein feed. It can be used to feed animals with nutrition and reduce feeding cost. In our country, about 250,000 tons of pig blood are slaughtered each year. Based on the protein content of 18.9%, there are 47,000 tons of pig blood protein. However, if pig blood is directly dried into blood meal feed, its protein absorption efficiency is low, the taste is fishy, and the palatability is poor. Summary of the invention [0003] In view of the shortcomings of the above-mentioned technology, the present invention provides a method for fermenting pig blood protein feed, which has good effect of degrading pig blood, simple process and low cost, and the prepared pig bloo...
