ca exist in every cell of the body, the calcium component of about 1-1.5% of the entire body, accounting for 98% of bone is bone, composed of the most important element. Calcium and participate in many physiological processes (muscle contraction, blood coagulation, the release of hormones, neural response, etc.).
p in the body mainly in the bone (80%) and soft tissue (20%), it is the cells of the important elements of energy exchange is an important part of the nucleus. Phosphorus in the body composition of about 0.5-0.8%.
Dogs on the calcium intake, primarily through food, food as well as the ratio of calcium and phosphorus content of vitamin d is a very important indicator (not vitamin d will not be able to form bone tissue).
Adult dogs on a run, per kilogram of body weight per day should be calcium intake of 100 mg and 85 mg of phosphorus in order to basically meet the needs of the body. The best ratio of calcium and phosphorus should be between 1.2:1 to 1.4:1. Adult dogs at different times have different needs, such as the Bitch of pregnancy in labor a week before the increase in food 60% of calcium and phosphorus, that is, per kilogram of body weight per day would take about 160 mg of calcium and 140 mg phosphorus. In breast-feeding more attention should be paid to calcium and phosphorus content in food, because Bitch through breast-feeding will consume a large amount of calcium and phosphorus. If dogs in the blood calcium will reduce the calcium content, resulting in dogs easily startled, causing convulsions and even shock. According to the number of how many puppies, a Bitch needs per kilogram of body weight per day and 250-495 mg, 175-335 mg of calcium phosphate. Dogs, compared with milk of calcium and phosphorus content of milk richer in nursing puppies during the development of bone calcium and phosphorus are needed for the milk obtained through Bitch This Bitch is for a very heavy burden.
Puppies after weaning in the first two months of the skeleton is also very important development period, the puppy at this stage the amount of calcium and phosphorus needs of adult dogs is about 4 times.
The experts found Mastiff the case of bone lesions occurred more and more because in childhood Mastiff excessive intake of high-energy material, to the neglect of the ratio of calcium and phosphorus. Many people like to animal offal as a dog food, which foods are rich in phosphorus but the calcium content is very poor and could not meet the needs of dogs. Dog food is based on different types of dogs from the food processing, including bone meal and fish meal ingredients such as calcium, is an ideal dog food, dog owners buy dog food dog food to pay attention to the application type and age of the dogs, which It is very important.
