doi:10.3969/j.issn.1674-5817.2020.02.010

Abstract

Abstract: Objective To determine the main nutritional components of SPF golden hamster milk and compare with other rodents milk (mice, rats, guinea pigs), rabbit milk, cow milk and infant formula milk. Methods According to the national standard, the essential nutrients of golden hamster milk were detected by Kjeldahl and ICP-MS. The content of amino acids was detected by an automatic amino acid analyzer. Results The main nutrient contents of 100 g golden hamster milk were as follows: water 86.4 g, protein 6.94 g, fat 2.70 g, lactose 2.21 g, mineral elements calcium 120.00 mg, magnesium 20.10 mg, phosphorus 82.05 mg, zinc 1.470 mg, etc. The total content of hydrolyzed amino acids was 61mg/g, and the content of essential amino acids was 24.4 mg/g, accounting for 0.4 of the total amount of amino acids. Conclusion The milk of golden hamster is characterized by high protein, low fat and low lactose, which provides a scientific basis for the formulation of sterile golden hamster formula milk.
