Breeding management of mallard ducks

Adjusting the planting and breeding: The diseased ducks with low yield, discontinued production, soft feet, severe paralysis, overweight or lean, and no treatment value are eliminated in time, leaving the mallards with good production performance, healthy disease-free and excellent morphological characteristics as Ducks. In the adjustment, we also need to reserve enough male ducks according to the company's ratio of 1 to 6-7 to ensure the fertilization rate of the eggs and increase the production efficiency.

Scientific feeding: According to the adult duck production stage, weight, etc., the amount of feed and the proportion of the diet should be changed as appropriate, so that neither feed nor feed can be guaranteed. At the same time pay attention to calcium supplement, increase green feed and shrimp, snail, small fish and other animal feed to meet its demand for vitamins, trace elements.

Shelter hygiene: Keep the mallard ducks and sports grounds well drained and dry. Clean the floor every day and replace the bedding frequently. Set up enough nest boxes or place egg-laying areas on the walls to avoid laying eggs or contaminating eggs. Food troughs, drinking fountains are often washed, household utensils and fields are regularly sterilized, duck grounds and utensils can be disinfected with 2-3% caustic soda or 2% solution of Lysol, bathing pool water can be used to kill stars at a concentration of 1 to 2,000 disinfection. Winter and spring should pay attention to keeping warm and cold, to ensure that the shelter does not leak rain, not into the snow.

Quiet environment: Pay attention to keep the environment around the shed quiet, avoid disturbing and cause “flocking”, resulting in a decrease in weight and egg production rate. It is forbidden to set off fireworks near the duck house. Feed processing and loading and unloading should also be kept away from the duck house. Animals such as dogs, cats and rats should also be prevented from entering the duck house. In order to prevent the adult ducks from being frightened and escaped, Skynet should be deployed around the playground to create a good living environment for the ducks.

Defensive and deworming: Inject duck cholera, viral hepatitis, duck quail vaccine, etc. to prevent the outbreak of the disease. Observe the dynamics of the ducks in peacetime, and if sick ducks or suspicious individuals are found, they should be treated in isolation. In the abortion period, the following drugs can be used to de-worm the ducks: 1. Levamisole hydrochloride. 20 grams per kilogram of feed or drinking water, allow wild ducks to freely eat or drink, 2 times a day, even feed 3-5 days. 2. Insect nemesis. Each time 50 kg of duck weight per 50 kg with 5 grams of insect meal star powder, evenly fed feed. 3. Amprolium. Mix evenly in the feed at a ratio of 0.025% and feed for 3 days. During the deworming period, duck dung and litter shall be promptly removed; after the deworming is completed, the duck houses and utensils shall be thoroughly disinfected.

Chondroitin Sulfate is a kind of acid mucopolysaccharide extracted from healthy, edible and homebred animal cartilage or shark cartilage. It`s composed of Chondroitin Sulfate A, C and other various Chondroitin Sulfate. China Shark Cartilage Chondroitin Sulfate is widely presented in fish, mammalian and bird cartilage. Chondroitin Sulfate Sodium is the sodium salt of the sulfated linear glycosaminoglycan. Shark Cartilage Chondroitin Sulfate SodiumShark Cartilage Chondroitin Sulfate Sodium is widely used as a material for food ingredient, cosmetics, and medicine. Recently, the use of Chondroitin sulfate for the symptomatic treatment of osteoarthritis has become very popular.


Our Shark Chondroitin Sulfate is derived from pure Shark Cartilage with a content of 85%, 90% and 95%.


Only selects Shark Species which are not on the endangered list, therefore ensuring sustainability of this potential life saving supplement. Shark Chondroitin Sulphates has more effect on human health than Bovine Chondroitin, that is the effect on Eczema and cancer. The 1992 publication of William Lane's book, Sharks Don't Get Cancer, sparked a heated controversy between money-grubbing opportunists and medical orthodoxy. Although sharks do, in fact, occasionally develop cancer, shark cartilage was promoted as a natural "cancer cure" and all around wonder drug.
For some clinic experiments, Shark Chondroitin Sulfate also helps to cure Eczema, but it's not scientifically proved. This is a strong natural material to combat cancer.
