AbstractEighty eight Holstein cows and their calves were used to evaluate effects of various levelof intramammary infections on colostrum quality and calves health Average somatic cellcounts SCC in three treatments were 960 103 2137 103 5050 103 cells ml Treatments were arranged in an unbalanced completely randomized design with 3treatments according to LOG10 SCC Maternal Colostrum was fed immediately after birthin amount of 2 L Feeding Any calf that did not receive maternal colostrum was removedfrom the study Calves blood samples were collected at 0 h and 3 h after first feeding and42 d Dams blood samples were taken immediately after parturition Volume density andpH of the first milking was recorded Calves were housed in individual pens and were fedmilk from 3 d until 60 d at 10 of BW d Water and calf starter were offered free choiceafter 3 d Calves were weighted at 0 h 30 d and 60 d Health and fecal scores wereevalueted daily until 42 d Body length and withers heigth were evaluated at 1 and 60 d Colostrum analyzed for protein Lactose TS SNF pH and IgG Serum samples IgG wasdetermined Data were analyzed using MIXED procedure of SAS system No significantdifferences due to intramammary infections were detected for colostrum volume fat protein Lactose density TS SNF and IgG But pH increased significantly 6 29 6 36 6 39 for low medium and high SCCs respectively P 0 05 Calves birth weights IgGconcentrations at 3 h and 42 d ADG in Second thirty days after birth body length andheigth of withers showed no differences among treatments But ADG in first thirty dayswere significant 0 181 0 169 0 103 for low medium and high SCCs respectively P 0 05 Health and fecal scores were affected by infection Dams IgG were also affectedby infection 18 09 22 7 25 14 for low medium and high SCCs respectively P 0 01 Data indicated that intramammary infections can reduce calf health and performance butits effect on colostrum IgG is not significant
