PSXII-1 Effects of copper, zinc, and manganese source and concentration during late gestation on beef cow colostrum yield and quality.

Our objective was to determine effects of Cu, Zn, and Mn metal methionine hydroxy analogue chelates (MMHAC) on beef cow colostrum. Multiparous, fall-calving, Sim-Angus cows (n = 48; BW: 649 ± 80 [SD] kg; BCS: 5.3 ± 0.5; age: 4.3 ± 1.2 yr) were individually-fed tall fescue-based hay (12.2% CP, 61.5%...
