Basic knowledge of feeding and management of cultured mackerel

Raccoon I think many people do not understand it, but this name should be often heard, we can often hear someone say "the hair on my clothes is raccoon hair", which shows that raccoon hair in the industrial use is very wide.

Basic knowledge of breeding management of raccoon

I. Adjustment of mating body condition (winter solstice January 15)

Standard of mating body condition: According to raccoon's length (from ear to tail root), each cm ×2.2 is normal mating body condition. The adjustment of body condition can be divided into two stages:

1. Natural falling body condition: (winter solstice, December 1)

Raccoon enters hibernation period, appetite loss, feed once a day in the evening, food intake halved, generally each day face 1.5 liang, fish meal 4 money, food intake standard should be completely clean after feeding, add food as appropriate.

2. Artificial body condition: (December 1 to January 15)

Starting from December 1, adjust the body condition. First, weigh the weight of each raccoon dog once, measure the height according to the breeding body condition standard, see how to feed when the breeding body condition drops to January 15, make a good adjustment plan and control the food intake. Weigh again on December 10, measure how much you have dropped every day, and adjust according to the reduction to breeding body condition on January 15. This one phase feed presses face 9~7 money, fishmeal 4 money is appropriate. On December 10, the female raccoon dog was kept for medicine: E, cod liver oil rotation feeding;B1, compound B, C rotation feeding male and female raccoon dog, each one piece.

This stage, such as the slow decline in body condition, only reduce the face, not reduce fish meal. Until January 15 to breeding condition. (calculated as 2 liang per centimeter)

2. Feeding and management during mating stage:

1. Ascending body condition promotes estrus

From January 16 to improve body condition, increase protein feed, promote oestrus. Generally: face 7 money, fish meal 5 money, eggs 7 money, food to thin point, feed, noon to feed a small amount of carrots or vegetable leaves (amount in half two or so). Drugs: January 20 E to feed 100 mg, male and female raccoon dogs each day 1, other drugs with the same rotation feeding. From February 1 onwards, feed twice, morning and evening.

III. Management and methods of breeding period

1. The breeding time generally starts from the end of January to the end of March 10, and the best time is mid-February.

2, management: into the breeding period, the general face 8~9 money, fish meal 5 money, eggs 7 money, add carrots or vegetable leaves at noon, male raccoon dog noon plus an egg. Drugs: morning, B1, compound B, C round feed each one; evening, female raccoon dog 100 mg E1, cod liver oil 3; male raccoon dog 100 mg, cod liver oil.

3. Breeding method

① Estrus test: Generally from January 28 to observe the test, male and female raccoon estrus performance is night cage noise and cry, female raccoon water gate swelling and urine wet cage door brick. Every morning 5~7 o'clock, after 4 p.m., put the estrus performance with a clip into the male raccoon cage test, if the bite frame immediately pulled out, so every two days to try once. (This can promote male and female raccoon dog estrus quickly, but not frequently, forcibly, to avoid male and female raccoon dog mate selection) until the female raccoon dog naturally accepts mating.

Breeding method: breeding is generally from the first day of natural breeding with once, the second day with twice (morning and evening), the third day with twice, the fourth day with once, can be finished. To pay attention to match once the female raccoon dog wheel with other male raccoon dog to avoid empty bosom. May appear mate selection, it does not matter, which to let which match.

Feeding and management during pregnancy:

The management of this stage is divided into two parts:

1, 25 to 30 days of management: this period is very important, determine how many litters. At the end of breeding, it is generally necessary to weigh the weight, master the body condition after breeding, and know how much to add to each raccoon's food. Generally, it is mastered in a spoonful. Feed for 25~30 days, then slowly add, grasp on the spoon. Within 30 days, the face should be reduced to 5~6 money, fish meal 8 money, eggs 7 money, food should be diluted. When breeding, the body consumption is large, thin raccoon in 25 days plus face, consumption of small in 30 days plus face, every 5 days plus 2 money (plus 0.4 money per day), that is, 30 to 35 days, face 9 money to 1 liang, 45 days face added to 1.5 liang.

2, 45~60 days of feeding management: (determine the litter size is good or bad), 45~50 days face increased to 1.8 liang, fish meal increased to 1 liang. In addition, starting from 45 days, add a cooked egg at noon, add vegetables at noon, add 2~2.5 liang for 50~60 days, add fish meal to 1.2 liang, keep the egg and vegetable feeding method unchanged, and add some iodized salt appropriately. Pregnancy drug feeding method: morning B1, compound B, C round feed each tablet, evening 10 mg E feed 1 tablet a day, cod liver oil round feed 1 capsule each time;10 mg E feed 60 days to protect the fetus, until the seed so far. In addition, calcium tablets were added every morning for 40 days; yeast was added for 50 days, 4 tablets per meal.

In addition, within 60 days of pregnancy, fish meal and face should be prepared in sufficient quantity, with good quality, not replaced halfway, food intake should be controlled well, food should be sparse, the amount should be small in the first 30 days, and the amount should be sufficient after 40 days, but not excessive, according to the food plate completely licked after each feeding. If you see leftover food, you should add a spoonful less next time you feed it. If you can eat it clean, it will be enough. Pay attention to the observation and adjustment, no loss, but maintain a good appetite.

Feeding and management during lactation

1. Childbirth care: raccoon 2~3 days before birth begins to litter (that is, pregnancy, generally 57~58 days), generally normal feeding in the 60th day of birth, there are also delayed 3~5 days can be. Raccoon lost its wildness 24 hours before giving birth. Don't be afraid. Take good care of it. When giving birth, people will take care of it in front of the nest door to see if the female raccoon has peeled off the embryo and bitten off the umbilical cord when giving birth to the first baby. If it is normal, they don't need to take care of it. If they give birth to several babies, they may not peel off (usually die in 3 minutes). At this time, the caretaker will hook out the unpeeled raccoon with a prepared hook, quickly peel off the head and embryo by hand, and cut off the umbilical cord (leaving 1 cm long) with scissors. Dry with cotton or toilet paper and put it in a warm place in the house (at this time, the most afraid of cold).

Temporarily do not have to put back to the nest, such as peeling like dead, with the hand to do artificial respiration, short time can be saved. The female raccoon is very slow to give birth, generally takes 5 to 6 hours or longer, do not worry, the more to the later the need for care, then the mortality rate is high. After the female raccoon gives birth, use a clamp to clip the big female raccoon out of the nest and put it in other idle cages. Start to check the small raccoon: one is to count the number, the second is to see if the umbilical cord is entangled together, cut it open with scissors, the third is to see if the nipple of the big female raccoon dog is clean, squeeze the nipple with your hand, finally put the small raccoon dog and big female raccoon dog taken outside during nursing back into the nest, cover the nest to keep warm. After waiting for half an hour to listen to the nest quiet is normal, if not quiet, check the reason, generally will not be a problem.

2. Feeding: feeding female raccoon dogs three times after giving birth. Face about 2.5 liang, according to raccoon appetite, with the increase of raccoon appetite, face slowly increased. Fish meal 1 liang, increase fat feed, such as goat milk, lard, the amount should be less. Feed an egg at noon, eat to be thin, want to increase face along with appetite. Drugs: After the female raccoon dog gives birth, feed oxytetracycline for 3 days, one tablet per day, feed yeast for 4 tablets per day, feed other vitamins according to the feeding method when adjusting the body condition, and increase the frequency of C and cod liver oil appropriately. The raccoon begins to eat at about 18~20 days, and the lactating nurse is put in. Each raccoon has 1 piece per meal, and it can be less according to the situation. At this time, we should try to control the food intake of the raccoon to avoid excessive diarrhea.

Feeding and management after litter division

1. Feeding management 30 days after litter division

The raccoon begins to divide into litters in 45~50 days. If the growth in a litter is uneven, the big raccoon can be divided first, and 3~4 raccoon can be divided into a litter gradually later. The small raccoon can be kept by the female raccoon for a few days. Feeding within a month after litter separation is critical and determines its life. At this stage, due to the different birth time of raccoon, the amount of feed cannot be determined, but two standards should be grasped: one is to control the amount of food, after feeding the raccoon, the plate should be licked clean; the other is that no obvious belly can be seen after feeding. Food should be particularly thin (like porridge but not sticky), food intake control in each small raccoon 15 days before each meal to feed half a spoonful of rice. For the next 15 days, slowly increase to half a spoonful or one spoonful every day, that is, 5 to 7 percent full.

Feed can not be fixed quantity, generally master the total amount of face, fish meal 3:1 mix (such as 3 jin face, a catty fish meal). Face corresponding reduction, add appropriate amount of glucose, goat milk or milk powder, add feed essence. Drugs: each meal with appropriate amount of lactase, vitamin C, cod liver oil, B-based complex, according to the day round feed.

Feb. Feeding management from July to November

① July feeding method as above, food intake with raccoon growth appetite gradually increased. Face, fish meal by 4:1 collocation, eggs 3 money, drug feeding method ibid. Feed 7~8 into full, start to fight epidemic prevention.

② From August to September, feed only increased face, fish meal a day 4 money (eggs 2 money or only to the long slow small raccoon), drug cancellation, feed to 8~9 into full.

③ October to November to feed the face, fish meal increased to 5 money, to the end of October began to increase meat, generally chicken rack cheap, 3 money per day, from July to November face should be gradually increased to 3 liang to 3.5 liang per day. Early winter ~ light snow peeling.

Several problems should be paid attention to in breeding process

1. Setting of raccoon dog nest: the female raccoon dog should be sunny, and after the breeding nest in late winter, it should be covered with straw curtain and plastic. Can promote early estrus, male raccoon dog also want sunny warm place.

2. To ensure the normal growth of raccoon without problems, the most important thing is to control and adjust appetite. After feeding, the food tray should be completely licked clean. It is better to have no loss. Look at the feces to adjust the food intake. The black strips of feces are fine and hard, indicating that the food intake is slightly smaller; the feces are slightly soft and black, indicating that the food intake is normal; diarrhea indicates that the food intake is excessive.

3, feed ratio: generally 100 kg corn 20 jin wheat, 10 jin beans. Small raccoon sub-nest within 2 months beans reduced to 5 jin, this time beans high will cause indigestion.

From April to September, disinfect the inside and outside of the nest once a month with Baiji poison.

Prevention and treatment of common diseases of raccoon

1, diarrhea: diarrhea eating, mainly because of excessive food, food is not cooked or feed deterioration, find out the reasons for the corresponding adjustment. Treatment method: control food reduction, oral Qingda, according to the size of the raccoon appropriate 1~2 is appropriate, food plus norfloxacin or other intestinal anti-inflammatory drugs, etc., people use drugs according to instructions; diarrhea does not eat, people use berberine plus ribavirin, Antongding injection dosage according to instructions.

2. Cold: manifested as sudden eating or not eating, dry nose and head, injection of penicillin, antongding, dexamethasone each, one-half or one-third of 5 jin or less, twice a day, until normal.

3. Parasitic disease: main manifestations: gray nose, light eating, diarrhea and atrophy, self-biting hair. Treatment: Use veterinary anthelmintic drugs such as Yilijia and Afodin according to the instructions or according to the veterinary doctor's advice. Each raccoon should be treated once in July.

4, red claw disease (vitamin C deficiency) treatment: add vitamin C in the feed, wipe the claws with sulfur ointment, even wipe for 7 days.

Raccoon breeding in life is not very common, in the process of breeding will encounter a variety of problems, so a lot of understanding of some breeding precautions and breeding methods are very helpful for breeding.
