This study evaluated the effect of colostrum from Azawak cows on plasma protein profile, 24 growth, and survival in Red kids from Niger. Forty (40) newborn kids were allocated to one 25 of two treatment-groups: control (free access to water and the mother) and colostrum (free 26 access to water and the mother, but with additional 50 mL of colostrum/animal/day of birth 27 and 25 mL/animal/day from the 2nd to 15th day of age). Blood samples were collected into 28 EDTA vacutainer tubes by jugular puncture at 10 and 30 days of age. Total protein was 29 quantified by the Biuret method. The agarose gel electrophoresis was used to determine the 30 serum levels of albumin, -globulin, β1-globulin, β2-globulin, γ-globulin and the 31 albumin/globulin ratio. The animals from the colostrum group showed higher body weight 32 and average daily gain when compared to the control group (P < 0.001). The average 33 concentration in protein at the both sampling times reached higher values in the colostrum 34 than in the control group. At D10, the colostrum group tended (P < 0.07) to show higher 35 levels of -globulin and had higher values (P < 0.05) for β1-globulin. At D30, total protein 36 and β2-globulins were higher in colostrum group. Colostrum from Azawak cows seems to 37 have positive effects on some plasma proteins levels and on growth rate in Red kids.Peer reviewe
