In autumn, what nutritional level should be used to fill pets?

Autumn is the time for pets to get pregnant during the estrus period. The pregnancy and breastfeeding process should be a very unique process for pets. The nutritional regulations for dog food in this link are also the most unique, so the nutritional regulations for dog food in this link are also very special. In this link, pets usually show some abnormal symptoms that are the same as before, such as decreased appetite, nausea, physical depression, and dispersal. Nutrition during pregnancy is unique and critical. It plays a key role in the physical and mental health of the bitch, ensuring all normal growth and development of the baby, avoiding miscarriage, and the metabolism of the bitch's milk.

The nutrition of pet dogs during pregnancy is closely related to the baby's development, new survival rate of young dogs, vitality, physical fitness, and net weight of newborns. Effective nutrition should be provided thoroughly based on the nutritional physiological regularity of pet bitches and fetal babies, which is the key to determining the success and failure of pet breeding.

According to the growth and development of the fetal baby, the pregnancy period of the pet bitch is again subdivided. In fact, within 35 days of pregnancy, that is, 1 to 5 weeks of pregnancy - early pregnancy; within 49 days of pregnancy, that is, 5 to 7 weeks of pregnancy - middle and late pregnancy, and 49 days of pregnancy - day of pregnancy, that is, 7 weeks of pregnancy, 7 weeks of pregnancy, and late pregnancy. In the three stages of pregnancy, pet physiological metabolism has undergone unprecedented tremendous changes. At the same time, pets' maintenance, growth and development nutrition requirements will also have higher regulations and weekdays, and the development trends of the three stages within the pregnancy period have significantly changed. In the early and middle and late stages of pregnancy, the metabolism of pet pregnant mothers has increased significantly, with the average increase of 11% to 14%, while in the middle and late stages of pregnancy, it has reached 30% to 40%.

The growth and development of pet babies during this period of time also have staged weight gain. The early pregnancy is relatively slow and the second half of pregnancy accelerates. The fetal baby has a high fetal growth and rapid fetal growth in the early pregnancy. The key to 2/3 of the fetal weight increases in the second half of pregnancy.

The nutritional requirements of pregnant pets include the growth and development of pregnant pets, the uterus, the amniotic fluid of pregnant women and the baby, and the nutritional chemicals of pregnant mothers themselves.

1. Kinetic energy must

Pregnant mothers in the early stages of pregnancy must have a slightly higher kinetic energy than usual, and there is no major change or regulation; the needs of the middle and late stages of pregnancy have increased greatly, and the kinetic energy must basically increase by 10% to 30% while maintaining growth and development. In fact, it is 10% for 35 days to 42 days during pregnancy; 42 days to 49 days, an increase of 20% for pregnant women; 49 days to give birth, an increase of 30%. The pet metabolic energy requirement for pregnant dogs in the middle and late stages is 786.6KJ per kilogram of metabolic weight.

2. Protein must change the amount of protein nutrition needs. It is one of the more critical factors in this period. It is necessary to ensure that the young pets produced have a high survival rate, strong physical fitness, and rich and colorful milk secretion after giving birth. Protein nutrition is the strongest guarantee. During pregnancy, protein requirements should be significantly higher than 20% of the usual level. At the same time, it is stipulated that it is less than the level during breastfeeding. Each kilogram of metabolic weight must be metabolized 5~7g of protein. That is, the protein level is above 22% of crude protein per kilogram of dry matter foods as the minimum basic.

At the same time, the protein demand and kinetic energy demand are parallel to the protein demand. The protein demand has increased significantly in the second half of pregnancy, and there are also high regulations on the quality of the protein itself. It is stipulated that it can digest and absorb real proteins, and green plant proteins are correspondingly reduced. Animal classification proteins should account for 40~60% of the very proportion. It should also be ensured that sufficient sugar is given as electricity energy to avoid insufficient digestion and absorption of proteins.

3. Minerals must

Calcium, phosphorus, zinc, manganese, iodine, selenium and other minerals are crucial to pregnant mothers during pregnancy, and may have crucial effects on the quality of egg cells of pregnant mothers, the growth and development of fetal babies, and the growth and development of human bones of fetal babies. Therefore, the components of mineral nutritional chemicals should be increased in the middle and late stages of pregnancy, among which calcium should account for 1.2% and phosphorus should account for 1.2%. The highly recommended demand for dog foods is 1.1% calcium and 0.9% phosphorus.

4. Vitamins must

Vitamin A, vitamin E, and vitamin D are three vitamin nutritional chemicals that are more significant to pets during pregnancy among many vitamin types. During the pet's pregnancy, it will immediately endanger the growth and development of the fetal baby, the survival rate after giving birth, and the physical fitness after giving birth. During pregnancy, the bitch's vitamin needs should be twice the usual amount. According to dry matter pet food calculations, the recommended demand is vitamin A5000IU, vitamin E50IU, and vitamin D500IU. Pregnant cats must have vitamin A, vitamin E, and vitamin D every day, and each is 2100IU, 4.0 mg and 100IU.

At the same time, considering that pet pregnant mothers have unsuitable symptoms such as loss of appetite and fasting in the middle and late stages of pregnancy, the proposed feeding frequency is also adjusted accordingly. In the middle and late stages of pregnancy, feed 3 times a day, and in the middle and late stages of pregnancy, feed 4 times a day.

Puppy dog ​​food during pregnancy should also have both good flavor, comprehensive nutrition, balanced nutrition, easy to digest, easy to digest, and prevent excessive body fat. Only by ensuring the above aspects can it be considered the basic for pregnant women to succeed in childbirth and healthy and happy growth of young pets.
