The role of animal B-ultrasound in the management of female dogs before mating

The female dogs to be bred can be divided into two situations according to whether it is the first mating: one is the female dogs who have never bred and are mating for the first time; the other is the female dogs who have given birth and are in the empty period. For young female dogs who have not bred, their feeding level should be determined according to their physical condition before mating. If the dog is in good physical condition and has a moderate fatness, as long as the protein content in the feed is slightly increased at the beginning of the female dog's estrus, the female dog can be stimulated to ovulate normally. It is best to use animal B-ultrasound to check the reproductive system of the female dog, and even use animal B-ultrasound to measure the back fat of the female dog before determining the time of mating. If the female dog is relatively thin, it is necessary to increase nutrition in advance to restore its fatness before participating in mating: otherwise, due to insufficient nutrition supply, the female dog may suffer from dystocia, stillbirth, weak fetus, etc. In addition, female dogs are generally not involved in breeding during their first estrus, because the dog's body is not fully mature at this time and needs further growth and development. Breeding at this time is likely to affect the normal growth and development of the female dog, and it is also likely to cause dystocia, stillbirth, weak fetus, etc. Animal B-ultrasound should also be used to monitor the development of the fetus. Generally, breeding is performed when the female dog is in estrus for the second time. The feeding level of multiparous female dogs should also be determined according to the dog's fat condition. If the female dog's fat condition is good after measurement using animal B-ultrasound, no special feeding is required, and only short-term good feeding before breeding is sufficient. For female dogs with poor fat condition, nutrition should be strengthened to restore them to the fat condition that a breeding female dog should have as soon as possible. In addition, if the female dog is too fat, it may affect the normal estrus and ovulation of the female dog and the later pregnancy and birth. The feeding level needs to be reduced to reduce weight and restore it to normal fat condition. It should be noted that the feed for breeding female dogs must be safe and full-priced. In addition to the protein, fat and carbohydrates required for the female dogs to maintain their lives, trace elements such as vitamins and minerals must meet the needs of the female dogs, otherwise it may affect the normal estrus and pregnancy of the female dogs. In addition, the female dogs need to be provided with enough clean drinking water.

In terms of management, one thing that is easily overlooked is to ensure that the breeding female dogs exercise appropriately. Exercise can ensure their normal physiological functions, enhance the sexual activity of the female dogs, enable the dogs to estrus and ovulate normally, thereby ensuring normal pregnancy and birth in the later period, and frequently use animal B-ultrasound to observe the female dogs to see if there are any abnormalities. At the same time, the hygiene of the dog's body, kennels and dog activity places must be guaranteed to prevent the dogs from being infected by pathogenic microorganisms and parasites. The physical health of the breeding female dogs is the basis for normal pregnancy and birth. During the estrus period, the female dogs are excited and restless, and have a strong desire to mate. Management should be strengthened to prevent the occurrence of secret mating of female dogs.

The role of animal B-ultrasound in the management of pregnant female dogs

After the female dog has experienced normal estrus and mating, it enters the pregnancy period. The focus of feeding and management is to promote the normal growth and development of the fetus and prevent miscarriage. Animal B-ultrasound should also be used frequently to detect the fetal condition of the female dog and prepare for postpartum lactation.

In the first 2/3 of the pregnancy period, the female dog only needs to increase the amount of food. Because during this period, the fetus is in the differentiation and formation stage, the growth rate is slow, and the gestational sac of the fetus on animal B-ultrasound is very small and grows very slowly. Note that it is not advisable to overfeed in the early pregnancy, which can easily cause the female dog to become obese and affect its production. In the last 1/3 of the female dog's pregnancy, the fetus grows rapidly: during this period, the female dog's food intake also increases. At this time, in addition to increasing the amount of feed supply, the female dog should also be supplemented with some easily digestible, high-protein, calcium, phosphorus, and vitamin-rich feed, such as meat, offal, eggs, milk, etc. It should be noted that in the late pregnancy of female dogs, because the uterus occupies a large amount of abdominal space, the stomach of the female dog cannot dilate normally. It is best to eat more meals and less food every day, and feed 4 times a day. This is conducive to the digestion of food and the reduction of pressure on the uterus, and is also conducive to the growth and development of the fetus. However, in the late pregnancy, animal B-ultrasound should be used frequently to detect the growth of the fetus. At the same time, be careful not to feed too cold feed and drinking water, so as not to irritate the stomach and intestines, affect digestion, and even cause miscarriage.

In terms of management, miscarriage should be prevented. Pregnant female dogs are prohibited from strenuous exercise, whipping and intimidation are not allowed. The dog's body should be kept clean and quiet, so that the female dog can get enough rest, and animal B-ultrasound should be used frequently to check the condition of the embryo. After 40 days of pregnancy, the female dog should be raised alone, and the kennel should be spacious, clean, dry, and well-lit. Appropriate activities during pregnancy can not only increase the appetite of the female dog, but also be conducive to the growth and development of the fetus, and reduce the occurrence of dystocia in the female dog.
