METHOD FOR PREVENTING CLOTTING OF WHOLE MILK AND MILK REPLACER BY CHYMOSIN IN CALF ABOMASUM

Milk Replacer versus Whole Milk: Effects on Calf Performance

Introduction The use of pasteurized waste (i.e., nonsalable) milk as a liquid feed for calves has increased in recent years (NAHMS 2002; NAHMS 2007) due to greater availability of on-farm pasteurizers. Properly pasteurized waste milk can be a high-quality source of nutrients for young calves, and is oftentimes thought of as supporting superior calf health and performance compared with conventio...

Digestibility and blood parameters in the preruminant calf fed a clotting or a nonclotting milk replacer.

Eight male Holstein calves 7 to 10 d of age were fed a milk replacer containing a skim milk powder subjected to low-temperature drying either with or without addition of an oxalate-NaOH buffer known to prevent curd formation. The calves were used in a completely randomized design to study the effect of milk clotting on digestibility and blood parameters. Plasma glucose and plasma insulin were s...

Effects of spray-dried whole egg and biotin in calf milk replacer.

Holstein bull calves (n = 120) were fed milk replacers containing 0, 10, or 20% of the formulation (0, 22, or 44% of crude protein) as spray-dried whole egg powder in a 56-d feeding trial. Milk replacer was medicated with oxytetracycline and neomycin and was fed from d 1 to 42 of the study in a phase-fed program. All experimental milk replacers were supplemented with B vitamins, except biotin. ...

Determination of plasmin (alkaline milk proteinase) and chymosin in milk products by the ELISA assay

Effects of additional milk replacer feeding on calf health, growth, and selected blood metabolites in calves.

The objective of the experiment was to evaluate effects of increased milk replacer feeding on growth, intake, feed efficiency, and health parameters in stressed calves. Holstein bull calves (n = 120; approximately 3 to 8 d of age) were purchased from sale barns and dairy farms and housed in fiberglass hutches. In addition, wood shavings contaminated with coronavirus were mixed with clean shavin...
