Selection method of deer species
First of all, deer, take a closer look at the overall level of the field. To the farm first look at the number of columns, if the number of individuals do is low, may be more inbreeding. Inbreeding can be avoided in the big market. Secondly, we must choose a formal breeding farm with breeding qualifications to buy it.
It is important to choose deer. A look at pilose antler. The best way to choose a male deer is to buy it before the velvet antler growing season, when it is clear at a glance whether the velvet antler is big or small, good or bad. If the velvet antler has been sawed off, it will look like it. The head is big, the eyes are bright, the height is right, and it is not too high. Second, it depends on the eating ability of the deer. Deer in the same deer farm eat the same feed. Deer that love to eat, have strong digestive function and look fat is an ideal choice. In addition, the deer with better tolerance to rough feeding are easier to feed.
There are also skills in selecting fawns. Experts believe that young deer can't tell whether it's good or bad. Deer of the same age choose a big one, go back and choose their cubs, eliminate the bad ones, and stay with the good ones. As for whether it is better to buy a big one or a small one, it depends on your financial ability. if you have strong economic ability, you can buy some big deer for development. buying small deer has a very long turnover period and cannot be developed in a short period of time.

Application of antibiotics in snake disease
Antibiotics, formerly known as antibiotics, are metabolites of bacteria, fungi, actinomycetes and other microorganisms. Their low concentration can inhibit or kill pathogenic microorganisms and systemic bacterial infections. It is one of the most commonly used and indispensable high-efficiency drugs in clinic. It is also suitable for the prevention and treatment of snake disease. Practice has proved that injecting antibiotics into snake bait can not only prevent snake diseases, but also improve snake metabolism, promote growth, increase survival rate or feed conversion rate. The commonly used antibiotics are penicillin, erythromycin, cephalosporin and chlorine.

Red-headed snake-necked turtle
The Chinese name red-headed snakehead turtle is distributed geographically in Venezuela, Colombia, Ecuador, Peru, Bolivia, Guyana and Brazil. The mode of reproduction is to lay eggs. Females can be distinguished by their tails (of course, long and thick tails are male). It can mate all year round. Female turtles can lay 4 to 6 eggs at a time, sometimes laying eggs far away from the water source. Habitual crooked-necked turtles are basically aquatic, but are often found walking on land after rain. The three animals I keep in captivity spend more time on land than they do in the water.
