Embodiment 1

[0017] Use canola meal and soybean meal as the main protein source to prepare submerged feed for tilapia (crude protein content is 26.6%, crude fat content is 4.7%), which contains 1% of tilapia feed premix of the present invention. The tilapia premix formula used is that each kilogram of tilapia feed premix contains vitamin A 400000IU, vitamin D 3 200000IU, Vitamin E 2000mg, Vitamin K 3 500mg, vitamin B 1 500mg, vitamin B 2 1000mg, Vitamin B 6 600mg, vitamin B 12 2mg, inositol 5000mg, vitamin C 7000mg, niacinamide 3500mg, D-calcium pantothenate 2000mg, folic acid 160mg, biotin 8mg, magnesium 5000mg, iron 5000mg, manganese 950mg, iodine 160mg, copper 750mg, zinc 4000mg, selenium 25mg, cobalt 125mg , lysine 150g, methionine 120g. The prepared feed is raised to 500g (marketing specification) of 20g Jifu tilapia in the farm of Dadapo Town, Haikou City, Hainan Province. The protein deposition rate can reach 49.2%, the protein efficiency can reach 2.89, the feed coefficient ca...

Embodiment 2

[0019] With Canadian canola meal and soybean meal as the main protein source, the tilapia submerged feed (crude protein content is 26.6%, and crude fat content is 4.7%) is prepared, which contains the tilapia feed premix 1 described in Example 1 %. The prepared feed is raised to 500g (marketing specification) of 20g Jifu tilapia in Wenchang City, Hainan Province. The protein deposition rate can reach 48.4%, the protein efficiency can reach 2.85, the feed coefficient can be reduced to 1.35, and the weight gain rate can be increased. 18.52%, saving 13.90% of feed cost. However, under the same culture conditions in this culture area, the culture effect of the tilapia 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 35.4%, the average protein efficiency is 2.08, and the average feed coefficient is 1.6. According to statistics, there is a significant difference between the above-mentioned adde...

Embodiment 3

[0021] With Canadian canola meal and soybean meal as the main protein source, the tilapia submerged feed (crude protein content is 26.6%, and crude fat content is 4.7%) is prepared, which contains the tilapia feed premix 1 described in Example 1 %. The prepared feed was raised to 500g (market size) of 25g of Jifu tilapia in the farm of Ding'an County, Hainan Province, which can make the protein deposition rate reach 49.9%, the protein efficiency reach 2.94, the feed coefficient is reduced to 1.31, and the weight gain rate is increased. 18.32%, saving feed cost 12.20%. However, under the same culture conditions in this culture area, the culture effect of the tilapia 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 39.2%, the average protein efficiency is 2.3, and the average feed coefficient is 39.2%. is 1.55. According to statistics, there is a significant difference between the above-men...

Abstract

The invention discloses a tilapia feed premix and an application thereof. The tilapia feed premix is composed of limiting amino acid, a vitamin complex and composite mineral salt. In the invention, plant raw materials such as rapeseed meal, cottonseed meal, soybean products and the like are taken as main protein sources, and 1% of the tilapia feed premix is added to the raw materials to prepare a tilapia submerged compound feed or an extruded feed for cultivating tilapia, which can achieve protein deposition rate up to 48%, improve protein efficiency to 2.85, lower feed coefficient to 1.35 and save feed cost by 12.20%-13.90%. The tilapia feed premix of the invention is of great practical significance for improvement of feed utilization of the tilapia, growth promotion and the like.

Description

technical field [0001] The invention relates to the field of feed, in particular to a tilapia feed premix and application thereof. Background technique [0002] my country is the world's largest tilapia farming production and exporting country, and artificial compound feed is used throughout the tilapia farming 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 determining the overall quality of tilapia feed. When the ratio of basic feed raw materials (protein source, sugar source and fat source) remains unchanged, it can be adjusted precisely by adjusting the formula of premix. Control the various physiological needs of tilapia. Protein source accounts for the largest proportion of cost in tilapia feed formula, and its utilization rate is an important link in determining f...
