Problems solved by technology

The advantages of extruded feed are obvious, but its high temperature and high pressure manufacturing process also leads to the inactivation of the microecological preparations added to the compound feed to regulate the intestinal tract and lose its effectiveness

Embodiment 2

[0036] Embodiment 2 breeding effect contrast

[0037] By cultivating on-site in ponds, the feed of Example 1 and the existing feed of Comparative Example 1 were compared in the breeding effect of Macrobrachium rosenbergii compound feed, and the comparison results are shown in Table 1.

[0038] Table 1

[0039]

[0040] It can be seen from Table 1 that the extruded biological compound feed produced by the new process and the common extruded compound feed have aquaculture data. It can be seen that the extruded biological compound feed produced by the new process has obvious advantages in loach breeding.

Abstract

The invention provides a preparation method of biological expanded compound feed for loach. The feed comprises imported super fish meal, peeled soybean meal, peanut meal, cold-pressed rapeseed cakes,cuttlefish paste or squid paste, imported chicken powder, corn protein powder, high-gluten flour, soybean oil, calcium dihydrogen phosphate, a micro-ecological preparation and a premix. The preparation method comprises the following steps that after superfine grinding all raw materials except the soybean oil and the micro-ecological preparation are mixed, and then the mixture is subjected to superfine grinding, secondary mixing, steam conditioning, puffing, drying, oil spraying, cooling, screening and quantitative packaging; oil spraying is carried out, wherein the micro-ecological preparationis added into the soybean oil and uniformly stirred, and then the outer side of the expanded feed is coated with the mixture. The micro-ecological preparation originally placed in the premix is dissolved in the soybean oil and then sprayed on the outer side of the expanded feed. In this way, destructive inactivation of the micro-ecological preparation during high-temperature high-pressure operation of the expanded feed is avoided.

Description

technical field [0001] The invention relates to a preparation method of loach bio-expanded compound feed, which belongs to the technical field of aquaculture. Background technique [0002] Loach (scientific name: Misgurnus anguillicaudatus), belongs to Loach family. The body is small, slender, only three or four inches. Moreover, it has a round body, short body, small scales under the skin, black in color, and is covered with its own mucus, so it is slippery and difficult to hold. The anterior segment is slightly cylindrical. The rear part is flattened, the abdomen is round, the head is small, the mouth is small, and the lower position is horseshoe-shaped. Eyes small, no undereye thorns. Must be 5 pairs. Loach is widely distributed in China, Japan, Korea, Russia and India along the coast of Asia. Distributed all over China. It is more common in the south and less common in the north. It can be harvested throughout the year, most in summer. After the loach is caught, ...
