The effect of different starters on performance and physiological characteristics of early-weaned female Holstein calves

The objective of this research was to determine the effect different starters consisted dried whey and soy proteins with low anti-nutritive factors (ANFs) + amino acids (lysine methionine) on body measurements, biochemical parameters, feed consumption early-weaned female Holstein calves. Based starter, calves were divided into four groups: i) control (control starter), ii) E1 (starter added dry whey), iii) E2 ANFs lysine methionine), iv) E3 methionine). Results indicate that based powder methionine significantly affected milk replacer total matter, then withers in height, length (among traits) as well NEFA blood parameters) Finally, could be recommended optimize growth consumption.
