Saving the perfect hay and rising the winter protein complement – Does that meet her wants?

If a producer fed 28 lb (as fed foundation) of top quality hay (58% TDN; 13% CP) and three.5 lb of 20% protein cubes to a 1400 lb lactating cow, the cow’s protein wants would seemingly be met, however the vitality supplied would fall quick, inflicting the cow to shed extra pounds. The chilly winter coupled with many inches of snow cowl throughout most of Nebraska has made it troublesome for cows to keep up physique situation over the winter.

If grazing had been deferred till June, a March-born calf could be three months previous by the point grazing was accessible. This calf would seemingly be consuming at the least 1% of its physique weight in forage on a dry matter foundation. Subsequently, a 300 lb calf would eat about 6 lb (as fed foundation) of the instance TMR above along with milk from the cow. Another choice producers may take into account is offering a creep gate to permit the calf entry to their very own TMR in a special pen, or a creep feeder by which they supplied a industrial creep feed. Feed prices have to be evaluated as pelleted and bagged feeds are usually dearer than mixing a weight loss program from bulk commodities on website.

Different issues for the confined calf

Confined calves are seemingly uncovered to the next pathogen load than grazing calves.
