Changes in Amino Acids Profile of Camel Milk Protein During the Early Lactation

Azza M. Kamal, Omar A. Salama and Kamla M. El-Saied
The aim of the present study was to characterize the changes occurring in amino acids profile of camel milk protein during the 1st month of lactation and seek to justify such dynamics of change in relation to the specific needs of growing neonates. Milk samples were collected from camels at varying stages of lactation from the 1st day till 30 day of parturition. Daily samples were tested for fat, protein, lactose, ash and total solids %. The respective mean values at parturition were 0.50±0.06, 12.99±0.20, 2.75±0.40, 0.96±0.037, 20.25±2.50, while at the 30 day the respective mean values were 3.78±0.68, 3.30±0.25, 5.85±0.43. 0.70±0.040, 15.06±1.45. The mean of different amino acid values at the 1st day were significantly increased then sharply decreased in the 3rd day and continuously decreased till reach to the 5th day after that slightly decreased in the 7th day. So, we noticed a non significant decreased in the reminder time, 10, 15, 21 and 30 day, respectively. While there is a significant increase in the level of serum insulin growth factor-1 at zero time and then began to decrease till 30 days. At the same time, concentrations of triiodothyronine and thyroxin were very high at birth and then decreased to relatively low concentrations on day 30. This study demonstrates that camel milk during the 1st month of lactation have important effects on clinical, metabolic and endocrine traits.
