Abstract
Forty-eight Holstein calves were fed one of four liquid diets from 3 to 30 days of age to compare sodium benzoate, propionic acid, and formaldehyde as preservatives for colostrum. Colostrum batches were fermented at temperatures of 20 degrees C or higher. Diets were 2.73 kg of 1) naturally fermented colostrum, or colostrum treated with 2) sodium benzoate (.5% by weight), 3) propionic acid (1.0% by weight), or 4) formaldehyde (.05% by weight). Colostrum diets were diluted with .91 kg water. Prior to feeding, 25 g. sodium bicarbonate was added to liquid diets of one-half the calves on each treatment. Liquid diets were fed once daily. Water and a 15% crude protein complete starter were offered for ad libitum consumption. Calves were weaned abruptly at 30 days of age and received only water and starter from 31 to 44 days of age. Daily gain from 0 to 4 wk and 0 to 6 wk favored calves fed colostrum treated with sodium benzoate or propionic acid. Gains from 0 to 6 wk were .33, .44, .45, and .32 kg/day for the four diets, and feed efficiencies (kg dry matter intake/kg gain) were 3.23, 2.36, 2.76, and 2.89 during the same period. Addition of sodium bicarbonate to colostrum diets improved intake during the 1st wk of feeding. Gain and feed efficiency were similar during wk 0 to 4 but favored slightly calves not receiving sodium bicarbonate during the overall study, wk 0 to 6. Daily gain and efficiencies during wk 0 to 6 were .41 and 2.53 for calves without .36 and 3.01 with sodium bicarbonate added to colostrum diets.(ABSTRACT TRUNCATED AT 250 WORDS)
