Document Summary

Lecture 1: meeting the needs for specific stage of production requirements, beef cow: experts stat that should only feed to meet requirements for o(cid:374)l(cid:455) (cid:1005)(cid:1004)(cid:1004) da(cid:455)s of the (cid:455)ea(cid:396). Limit what is being put back into the soil. Concerns with excess nitrogen, phosphorus, sodium, and other minerals. Hay: target so that it contains <15% moisture. Npn does(cid:374)"t contain amino acids, peptides, protein. Much of this npn can get wasted depending on the quality of carbohydrates fed to the animal. Lecture 1: how does this affect utilization for a lactating dairy cow, feather meal: high in protein but does not have high amounts of essential a. a. Low essential aa content can result in much of this protein being broken down and the n excreted into the urine to enter the environment: availability of the nutrient in the feedstuff: phytate-p in cereal grains.
