Abstract: Colostrum is a natural product, issued by both mammals and humans in the first week of lactation. Among different species, donkey colostrum is considered to have, in addition to a valuable composition in nutrients and immune factors, an outstanding similitude with human colostrum. In this context, and taking into account the scarcity of available data concerning the interaction between climate factors and colostrum quality, a trial was conducted aiming to identify the possible influence of environmental factors on donkey colostrum nutritional traits. A stock of 175 jennies from 7 farms located in Cluj and Sălaj Counties was analyzed over a 7-day postpartum period. During the experimental period, the daily temperature, humidity, and wind velocity data were collected. Strong positive correlations are reported between the studied colostrum nutritional traits (fat, protein and lactose). Testing the impact of some environmental parameters upon nutritional content of donkey colostrum indicated three factors that have an influence on the nutritional quality of donkey milk colostrum, labelled as: colostrum nutritional traits, environmental air traits and some colostrum nutritional traits, and climatic traits and some colostrum nutritional traits.
