ANSC 1111 Lecture Notes - Lecture 16: Short-Chain Fatty Acid, Dairy Cattle, Silage
Document Summary
Feeding the dairy herd accounts for 45-60% of the total costs to produce milk. Example: income . 00/100 lb milk: feed cost /cow/d. Balances the ph in the rumen because volatile fatty acids (vfas) are. Types of feeds that are typically fed to dairy cattle. Soybean meal (high protein and high energy) Forages make up the major portion of the dairy cow ration. Packed so it can go through fermentation. Quality is much better when you feed it months after preparation. Grasses and legumes can be used to make hay, haylage, and baleage. One of the least expensive ways to feed forages. No rain, it drys up, quality decreases. Eating the same quality, so by the time they get to the original plot, it has regrown and is similar to the same source of feed. Esophagus goes into the rumen, which is the largest compartment. Majority of fermentation occurs in the reticulum. Rumen microbes (bacteria, protozoa, fungi) present in the rumen.
