In recent years sugarcane had been farmed in large quantities in Iran especially in Khoozestan state due to proper climate. By-products that remain after processing of sugarcane are Lignocellulosis materials contain more than 20% lignin. 700000 ton bagasse pith is produced yearly at Khoozestan that might be used in animal nutrition because industrial usage is limited. Supplying fiber requirement of ruminants in Iran because of hot and dry climate needs attention to new sources of fiber. Bagasse had been used intact in some countries or just with molasses and urea in fattening farms. Bagasse had been used in low milk production cows (1). A new technology (Steam treatment) had open new zones to apply bagasse as steam treated bagasse in ruminant nutrition and had been shown that it is more digestible (2). This study was conducted to use hydrolyzed bagasse pith in high producing dairy cows in early lactation.

Genetic Value

Improvement of the genetic value of cows, enabling increasingly high milk yield, requires increasingly modern feeding. Therefore, in addition to high-quality bulky feed and concentrate feed, specialized feed additives are being introduced to the diet of high-producing dairy cows. The available additives (rumen-protected essential ingredients, phytobiotics, probiotic, prebiotic and others) have a broad spectrum of activity, increasing production efficiency, protecting against metabolic disease, and improving the reproductive parameters and health of the herd. It should be borne in mind, however, that only rational use of feed additives in the diet of cows is conducive to their longevity, which is one of the most important factors improving the economic outcomes of milk production.

Different Levels

Tolkamp et al. (1996) reported that dairy cows were able to choose between complete foods with different MP:ME ratios, and it was concluded that the selection the cows made was not random. Diet selection may remove nutritional constraints on milk production if the cow can choose the appropriate protein level to attain the milk yield determined by her genotype. At a specific DUP content the diet of an individual cow will be correctly balanced. When the cow is offered two foods, one in excess of predicted requirements for DUP, the other deficient in DUP for the predicted level of production, then the cow has the opportunity to select a diet which exactly meets her requirements for DUP. Most diet selection experiments have been completed under conditions of little or no competition; the aim of the experiment was to study the effects of offering lactating cows a choice between two protein concentrates under semi-commercial conditions.
