The proper addition of citrus peel in the diet has no adverse effect on pig production. Fermentation can improve palatability, improve nutritional value, save feed resources, reduce feed costs, improve economic efficiency, and reduce pollution caused by citrus waste disposal. It has obvious ecological benefits.
First, the application of citrus peel in pig feed
Adding 10% citrus peel powder to the growth and finishing pig feed is beneficial to improve the growth performance, improve the carcass quality and reduce the thickness of the back. The citrus peel is dried by microbial fermentation, and the wheat bran is replaced by the ratio of 10% to 15% to the fattening pig diet. The fermented citrus peel has good palatability to the finishing pig, and there is no feeding and weight gain for the pig. influences.
Fermented citrus peel for pig feed has no toxic side effects, and has obvious economic and social benefits. In the case of equal energy and other proteins, 50%, 100% of rapeseed meal (8%) in growing pig basic diet was replaced with fermented summer orange peel residue, and its growth performance, serum total protein, albumin, There was no adverse effect on globulin and white ball ratio; serum urea nitrogen content in 50% replacement group was significantly lower (P<0.05), digestibility of dietary protein and dry matter was significantly increased (P<0.05); 50% and 100% substitution The feed cost of the group was reduced by 2.43% and 4.85%, respectively, and the feed cost per kilogram of weight gain was reduced by 0.06 yuan and 0.23 yuan, respectively. It is proposed that the fermented summer orange pomace protein feed can completely replace rapeseed meal.
The feed intake and daily gain of pigs decreased in the first 4 weeks after adding silage citrus slag in the diet, but had no effect after 4 weeks; the addition of silage citrus slag significantly reduced the number of Enterobacter in pig manure, but had no effect on Lactobacillus; The addition of silage citrus slag to the diet has a tendency to reduce the thickness of the backfat and increase the oleic acid content in the subcutaneous fat.
Stainless Steel Channel steel is a long strip of steel with a groove section shape. With the same I-beam, stainless steel channel steel is also divided into ordinary channel steel and light channel steel two, the model and specification of the same way to waist height (h)× leg width (b)× waist thickness (d) millimeters.
Stainless steel channel :(1) hot rolled stainless steel ordinary channel steel main uses: ordinary channel steel is mainly used in building structure, vehicle manufacturing and other industrial structure, often used with I-steel with cattle yard people.(2) Hot rolled stainless steel light channel steel (YB164-63) hot rolled light probe Fu ox channel steel is a kind of steel with wide legs and thin walls, which has better economic effect than ordinary hot rolled channel steel. Its specifications range from 5-40#. The 1966 standard specified specifications ranging from 10-40#. Main application: construction and steel frame structure.
Stainless steel production commonly used stainless steel channel steel materials are: 201,202,301,304,321,316,316 L, special materials can be customized.
