Processing of fox mink feed

Fur animals mink, fox canine teeth developed, short digestive tract, small stomach volume, no caecum, food through the digestive tract fast, and digestive gland secretion of amylase less, lipase more, therefore, its feed should be animal feed, especially animal protein feed in the diet should account for a large proportion. Therefore, mink, fox feed processing modulation method has obvious characteristics, is introduced as follows:

1. Selection of materials

Meat feed to remove large fat, livestock viscera should be removed gallbladder, thyroid gland, dry animal powder and grain powder to remove lumps, impurities or foreign matter, vegetables to remove roots and remove yellow leaves, rotten leaves.

Fish meal and bone meal should be soaked in clean water for 4~6 hours (2~3 times of water change), light dried fish soaked for 1~2 hours (2~ 3 times of water change), alkali dried fish soaked for 1~2 days (2~3 times of water change every day), silkworm pupa powder, blood powder and liver residue powder as well as poor quality dried fish and dried stomach organs, etc., in addition to full soaking, but also cooking processing.

IV. Cooking

Poor-quality meat, fish and internal organs of livestock and poultry shall be cooked after disinfection by potassium permanganate; freshwater fish shall be steamed for 2 hours; pork with pox shall be treated at high temperature and high pressure after fat removal; grain flour shall be fully steamed by adding water, and each kilogram of grain flour can be cooked into 1.8~ 2kg of corn flour, or fried into fried noodles and then washed with boiling water to make thick porridge; fresh beef and sheep milk shall be heated and disinfected, milk powder shall be diluted with boiling water; eggs shall be cooked; Blood powder should be boiled before feeding, and then mixed into feed; spinach, cabbage after washing with boiling water to remove bitter taste.

All heat-treated feed must be cooled before mixing.

V. Weighing

According to the feed varieties and quantities specified in the feed mix sheet, weigh and check the weight respectively.

VI. Mincing

Feed that needs to be processed is ground separately with a meat grinder for later use. Feed that is too large in volume can be cut into small pieces by a knife and then ground. Rabbit head, rabbit skeleton and other hard feed, should first be crushed with a grinder, and then twisted again.

VII. Modulation

The feed processed in the previous process is concentrated in the mixing tank, and then milk, water (or soybean milk) and other supplementary feeds are added according to regulations.

Feed preparation should be appropriate for thin consistency, lactating mothers and young weaning feed can be slightly thinner. Keep the feed room clean and sanitary regularly, wash the processing equipment frequently and disinfect it regularly to prevent bacterial infection and infectious diseases.
