Abstract
The invention discloses a feed formula for goldfish in a growth period and a preparation method thereof and belongs to the fields of agriculture farming and goldfish breeding. The feed formula comprises fish meal, soybean meal, peanut meal, rapeseedmeal, flour, bran, monocalcium phosphate, astaxanthin, betaine, soybean lecithin, fish oil, soybean oil, vitamin and microelement premix. The method comprises the following steps of (1) crushing fish meal, soybean meal, peanut meal, rapeseedmeal and bran through a 60-mesh screen, weighing the crushed raw materials and then evenly mixing the crushed raw materials with betaine and astaxanthin at a ratio; (2) weighing soybean lecithin, fish oil and soybean oil, and stirring and mixing the soybean lecithin, the fish oil and the soybean oil evenly;and (3) mixing a mixture obtained in the step (1) with the mixture obtained in the step (2) evenly, and preparing a feed with the particle size of 2.0 mm by a granulator. The prepared feed nutritioncomposition for the goldfish in the growth period has the effects of being abundant in nutrition, good in palatability, gorgeous in body color and high in disease resistance; and the death rate of thegoldfish fed with the prepared feed is significantly reduced in comparison with that fed with a commercial common feed.
Description
technical field [0001] The invention belongs to the field of agricultural goldfish breeding, and in particular relates to a feed formula for goldfish growth period and a preparation method thereof. Background technique [0002] At present, the feed preparation of ornamental fish at home and abroad mainly refers to the research results of edible economic fish. However, the two have different feeding goals. colour, body shape and health. In the intensive farming mode, the unreasonable design of the nutrient level of the compound feed of ornamental fish will easily have a great impact on the growth and health. [0003] The number of goldfish breeding in my country is large, and most of them are high-density extensive farming. With the research and development of modern compound feed, goldfish farming has gradually changed from feeding natural bait to feed farming. However, the development of domestic goldfish feed is immature at present. In order to improve the protein savin...
