Feed and nutrition fat for raccoon dogs
In feed composition analysis, all substances that can be extracted with ether are called crude fat, which includes fat, glycerol and lipid compounds. Fat is an essential component of the body. Such as reproductive cells in the mitochondria, Golgi body components are mainly phospholipids, nerve tissue contains a lot of lecithin and cephalin, blood contains a variety of fat. Skin and hair contain a lot of neutral fat, phospholipids, cholesterol and wax. Fat is the main source of heat energy in animals and the best source of energy.

A New View on Disease Prevention in large-scale Rabbit Farm
Dilute the treatment, optimize the traditional rabbit breeding, pay more attention to treatment than prevention, and often turn the rabbit farm into a sanatorium for sick rabbits. In order to change this situation, some experts put forward the "five no treatments" for diseased rabbits, that is, rabbits that cannot be cured, rabbits with high treatment costs, rabbits with time-consuming and labor-consuming diseases, rabbits with low economic value after cure, and rabbits with strong infectivity and great harm. Practice has proved that after the implementation of this system in rabbit farms, the health status of rabbits has been significantly improved, severe infectious diseases have been effectively controlled, and medical expenses have been paid.

It's good to feed grass powder to deer.
The method of feeding straw powder to deer is very simple. Corn straw, bean straw, rice straw, wheat straw, peanut seedlings and dried leaves are ground into powder by a straw powder machine. Every 100 kg of straw powder is mixed with about 100 kg of warm water, and then stacked on the cement floor, or put in a special pool for 2 to 3 hours to ferment and soften. Then mix the mixed concentrate (corn flour, bean cake, salt, bone meal, etc.) with fermented grass meal, and then ferment for 2-3 hours before feeding the deer. The biggest advantage of feeding grass meal to deer is to improve the feed.

Application of phytase in diets of pigs and chickens
Phytic acid or phytate is common in plant feed, and most of the phosphorus exists in the form of phytate phosphorus. Phytic acid can form a stable complex with metal ions such as calcium ion, iron ion, zinc ion and copper ion, and can also combine with protein and starch, reducing the activities of endogenous amylase, protease and lipase. The digestibility of nutrients decreased significantly. Phytic acid is not absorbed by monogastric animals, and most of it is excreted in the form of feces, which not only greatly reduces the utilization rate of phosphorus, but also causes environmental pollution, especially water pollution.

Duck parasitic helminthiasis-duck subclonorchiasis
Duck clonorchis is a parasite that lives in the bile duct or gallbladder of duck liver. It mainly harms ducks over one month old, and the infection rate and infection intensity are very high. Death is often caused by blockage of gallbladder and bile duct worms, which is a great harm to ducks at present. There are two kinds of Clonorchis sinensis parasitic in the gallbladder and bile duct of ducks (Clonorchis orientalis and Clonorchis Formosa). The most common in clinic is Clonorchis orientalis. 1. Pathogen and epidemic characteristics the pathogen is Clonorchis orientalis, which belongs to the family epididymidae. The insect body is leaf-shaped and 2.4 to 4 years long.

Comprehensive Control of White Crown Disease in Chicken
First, clinical symptoms: the feed intake of sick adult chickens decreased slightly, mouth flow with blood and mucus, slow weight gain, dilute feces, mostly between 60-100 days old, and the mortality rate was about 0.2%. The main manifestations of laying hens were decreased feed intake, pale crown, decreasing laying rate, thinner eggshell and more abnormal eggs. Second, treatment: continuous use of Baiguanling or Baiguanjing for 5-7 days can achieve significant results. The feed intake of adult chickens increased significantly, stopped dying from 3 to 5 days, and gained weight. Generally speaking, the laying hens began to improve obviously from 5 to 6 days, and the crown gradually changed.
