The cecum breaks down some previously undigested fiber, but the exact importance of the cecum remains unknown. Microbes digest about 30 to 50 percent of the fiber units, cellulose and hemicellulose, in the rumen. At times they are small, not appearing as much more than a knot-like structure, and at other times they can double or triple in size. These by-products are absorbed into the blood and are used as sources of nutrients by the animal. Rumen microbes digest simple and complex carbohydrates (fiber) and convert them into VFAs. The tissues in the reticulum form a network similar to a honeycomb. Most commonly, an ovary will increase in size in response to reproductive hormones with the appearance of one or both of two main ovarian structures, a corpus luteum (CL) or a large, fluid-filled follicle.

The muzzle is the black portion above the upper lip. use long and sharp teeth to tear food into small pieces. Segments in the groove formed by the pressure of atrium ruminis all of these work. This prevents milk or milk replacer from entering the rumen. This degradation and resynthesis process has advantages and disadvantages. Upon leaving the omasum, digesta passes into the abomasum, which is frequently referred to as the true stomach. The sternum of the cow is relatively wider, flatter, and longer than in the horse. Aside from storage, the rumen is also a fermentation vat. The cow knows not what hertailis worth until she has lost it. Gall:cleaning agent for leather, paints and dyes 3.

Again the visceral surface is flattened more or less by the pressure of atrium ruminis. During late stages of development, follicles grow and fill with follicular fluid. VFAs mainly consist of acetic, propionic and butyric acids and provide 50 to 70 percent of the cows energy, see figure 1. The end products from microbial fermentation are responsible for developing the rumen. During this phase, income should exceed expenses. Cattle can utilize roughages and other fiberous feedstuffs only through the action of microorganisms which are normally ingested on feed or obtained from other animals.

(Heat and acid treatment to reduce protein solubility are currently being studied as methods of preventing degradation, thus saving the amino acids for use by the animal.) 2. More grain or finely ground forages can cause the amount of acetic acid to decline to 40 percent, while the amount of propionic acid may increase to 40 percent. After ovulation, the remaining cells of the ovulated follicle are collectively transformed into luteal cells and form a corpus luteum (CL). Fermentation in the rumen is made possible by a very stable environment for microbial growth. The microorganisms also pass from the rumen to the lower digestive tract, where the are digested and their constituent protein, vitamins and other nutrients are absorbed and utilized by the animal. Express their feelings is directed dorsally and cranially relatively short and rounded in a cow generally longer flatter!
