What issues need attention in the feeding and management of pheasant chicks during the brooding period? The following introduces them to farmers from the aspects of drinking water and starting feed, temperature, humidity, density, ventilation and lighting: Timely drinking water and starting feed: pheasant chicks should start feeding 24 to 36 hours after hatching. Before starting feed, they should first drink water. It is best to add 5% glucose or 0.1% potassium permanganate to the drinking water. Chicks that do not know how to drink should be taught promptly so they can drink as soon as possible. Start feeding 1 to 2 hours after drinking water. The starter feed should be soft, palatable, nutritious and easy to digest. During the first 3 to 5 days, it is best to feed wet mixed feed. Remove leftover feed before each feeding. When starting feed, lure them to eat once every 2 to 3 hours, then gradually increase the interval. From 0 to 2 weeks, feed 6 times a day; from 3 to 4 weeks, feed 5 times a day. Generally, as age in days increases, feed intake also increases. When growth approaches adult body weight, the feed requirement tends to stabilize. Temperature and humidity control: the suitable brooding temperatures are: 1 to 3 days old 35 to 34°C, 4 to 7 days old 33 to 32°C, 2 weeks old 31 to 28°C, 3 weeks old 27 to 24°C, 4 weeks old 23 to 22°C, and after 5 weeks old maintain normal temperature.

Several aspects to note in roe deer introduction and breeding
The roe deer, scientific name dwarf deer, belongs to the order Artiodactyla, family Cervidae, and is a ruminant animal. The wild roe deer is a treasure from head to toe, with enormous comprehensive development potential. First, roe antler has the same growth process and similar medicinal value as deer antler, while raising roe deer costs far less than raising deer, and the techniques are simpler. To a certain extent, roe antler can be developed to replace deer antler; second, roe deer skin can be made into mattresses and has a moisture-proof effect. Summer skin lacks down hair and is called “sha pi”; after processing, it can be made into clothing for spring and autumn. The remaining leather board can be used to make summer clothing. Winter skin has more down hair and is suitable for making cold-resistant fur clothing. In addition, roe deer skin can also be made into many kinds of leather products, and roe deer blood, liver, kidney, bone, etc. each have their own unique qualities. The roe deer has no fat on its whole body and enjoys the reputation of “king of lean meat”; its meat is tender and delicious, rich in nutrition, and has the functions of warming the spleen and stomach, strengthening the heart and moistening the lungs, draining dampness, and prolonging life. With reform and opening up and the improvement of people's living standards, roe deer has become a high-grade wild delicacy in some hotels, restaurants, and tourist resorts, and roe deer meat is extremely scarce on the market and expensive. Illegal hunting is serious, and at the same time domestic breeding of wild roe deer has gradually developed. Artificial roe deer breeding has a short breeding cycle, simple techniques, low breeding costs, and high economic benefits.
