Embodiment 1

[0017] Taking Canadian canola meal and dehulled soybean meal as the main protein source to prepare grass carp extruded feed (crude protein content is 28.0%, crude fat content is 3.09%, starch content is 14.6%), wherein contains grass carp feed premix 1 of the present invention %. The grass carp premix formula used is that each kilogram of grass carp feed premix contains vitamin A 300000IU, vitamin D 3 100000IU, Vitamin E 2000mg, Vitamin K 3 300mg, vitamin B 1 300mg, vitamin B 2 600mg, vitamin B 6 400mg, vitamin B 12 2mg, inositol 5000mg, vitamin C 7000mg, niacinamide 2500mg, D-calcium pantothenate 1200mg, folic acid 160mg, biotin 4mg, magnesium 5000mg, iron 6000mg, manganese 800mg, iodine 125mg, copper 375mg, zinc 2500mg, selenium 10mg, cobalt 125mg , lysine 156g, methionine 84g. The formulated feed raised 500g of grass carp to 3500g (marketing specification) at the farm in Minmin Town, Zhongshan City, Guangdong Province. The protein deposition rate can reach 31.8%, the ...

Embodiment 2

[0019] Take common rapeseed meal and cotton meal as the main protein source to prepare grass carp submerged feed (crude protein content is 27.4%, crude fat content is 4.32%, starch content is 12.4%), wherein contains the grass carp feed premix described in embodiment one 1%. The formulated feed raised 500g of grass carp to 3500g (marketing specification) in the farm of Anxiang County, Changde City, Hunan Province, which can make the protein deposition rate reach 32.7%, the protein efficiency reach 1.92, the feed coefficient is reduced to 1.9, and the weight gain rate Increased by 10.53%, saving feed cost by 7.58%. And under the same culture conditions in this culture area, use the same feed formula but do not use the culture effect of the grass carp feed of premix of the present invention, protein deposition rate is 29.5% on average, protein efficiency is on average 1.74, and feed coefficient is on average 2.1 . According to statistics, there is a significant difference betw...

Embodiment 3

[0021] Taking Canadian canola meal and cotton meal as the main protein source to prepare grass carp submerged feed (crude protein content is 27.3%, crude fat content is 4.75%, and starch content is 13.6%), which contains the grass carp feed pre- Blend 1%. The formulated feed raised 125g of grass carp to 1100g in the farm of Dafeng City, Jiangsu Province, which can make the protein deposition rate reach 34.2%, the protein efficiency reach 2.01, the feed coefficient is reduced to 1.82, and the weight gain rate is increased by 9.89%, which saves feed Cost 7.31%. However, under the same culture conditions in this culture area, the culture effect of the grass carp feed that uses the same feed formula but does not use the premix of the present invention is that the average protein deposition rate is 31.1%, the average protein efficiency is 1.83, and the average feed coefficient is 2.0 . According to statistics, there is a significant difference between the above-mentioned added gr...

Abstract

The invention discloses a grass carp feed premix and application thereof. The grass carp feed premix comprises limited amino acid, compound vitamins and compound mineral salts. In the invention, plant raw materials are used as a main protein source, such as vegetable meals, cotton meals, soybean products, and the like; and if 1 percent of grass carp feed premix is added to prepare a submerged grass carp compound feed or an expanding feed for breeding grass carps, the protein deposition rate reaches 32 percent, the protein efficiency is improved to 1.9, the feed coefficient is reduced to 1.9, and the feed cost is saved y7.31-11.68 percent. The grass carp feed premix has significance for improving the utilization of the feed by the grass carps, promoting the growth, and the like.

Description

technical field [0001] The invention relates to the field of feed, in particular to a grass carp feed premix and its application. Background technique [0002] Grass carp is the largest fish farmed in my country, and artificial compound feed is basically used throughout the breeding process. At present, most feed production enterprises need to rely on R&D institutions or professional companies to provide feed formula or feed premix due to their own lack of research and development conditions. Feed premix is ​​one of the key factors that determine the overall quality of grass carp feed. When the ratio of basic feed materials (protein source, sugar source and fat source) remains unchanged, the formula of premix can be adjusted to precisely control the quality of grass carp feed. various physiological needs. Protein source accounts for the largest proportion of cost in grass carp feed formula, and its utilization rate is an important link in determining feed cost and quality....
