Previous experiments have shown important differences in milk production when mixed starch sources were replaced by mixed high quality by-products in high concentrate diets with hay as the forage (Sutton et al. 1987). The purpose of the present experiment was to compare rolled barley with sugar beet feed (SBF) in both molassed and unmolassed forms when given alone with grass silage in a high-concentrate diet. Additionally the effect of altering protein concentration of the concentrates was examined.

And Performance

Earlier studies (e.g. Dewhurst et al., 1996, 1999) have shown marked declines in forage voluntary intake as calving approaches. The resultant reduction in nutrient supply may compromise performance in the next lactation, because it coincides with a period of intense metabolic activity in preparation for the next lactation. Feeding concentrates to dry cows did not overcome this problem (Dewhurst et al., 1999). The objective of the current experiment was to investigate alternative dry cow strategies, using only high-quality grass silage, to minimise the severity and consequences for subsequent milk production of the reduction in nutrient supply in this period.

Preliminary studies at the Bernard Weitz Centre have shown that maize silage has the potential to increase forage intake and milk production. The trend towards earlier calving, encouraged by the Milk Marketing Board pricing policy, means that maize silage may not be available for early lactation; as most farmers rely on the current seasons crop, and few carry stocks over from the previous year. The objective of the current trial was to determine the eflect on forage intake and milk production of incorporating maize silage into grass silage based rations either from early or mid-lactation.

Providing adequate protein nutrition for high yielding dairy cows is essential if their milk production potential is to be achieved. However, oversupply of protein has detrimental effects on biological efficiency as well as having a negative impact on the environment due to greater excretion of nitrogen in animal wastes. The present experiment was conducted to investigate the response to protein concentration and degradability in the diet by dairy cows of differing genetic merit (GM).

Quota restricts the volume and butterfat content of milk at farm level. However there is no restriction on milk protein concentration. In a previous study in the present series, sucrose supplementation of cows in late lactation offered grass silage based diets increased milk protein concentration, while supplementation with sucrose and fishmeal increased protein concentration and the yields of milk, protein and fat plus protein equivalent to, or greater than, that obtained from the parent herbage. The present study was undertaken to evaluate the effects of partially replacing a concentrate supplement with sucrose and/or fishmeal, over a range of concentrate feed levels, on forage intake, milk production and composition.Herbage was harvested from the primary growth of a predominantly perennial ryegrass sward, unwilted, precision chopped and treated with a formic acid based additive (Add-Safe, Trouw Nutrition) at 2.85 l/t. A concentrate was formulated consisting of unmolassed sugar beet pulp, barley, soyabean meal and minerals and vitamins. Four complete diets were prepared consisting of the silage and either concentrate (20 g/kg fresh silage) (SC), concentrate and sucrose (each at 10 g/kg fresh silage) (SCS) concentrate and fishmeal (each at 10 g/kg fresh silage) (SCF) or sucrose and fishmeal (each at 10 g/kg fresh silage) (SSF).

Protein Supply

Energy and protein supply during the dry period can affect subsequent milk production and composition (Moorby et al., 1996). Grass silage is a common ingredient of dry cow diets, but although it is usually adequate in crude protein concentration (CP), a high proportion is frequently in non-protein forms. Red clover silage has shown interesting characteristics that would increase true protein supply to ruminants (Broderick et al., 2000), which could avoid the use of more expensive concentrate supplements. The objective of this experiment was to compare red clover and ryegrass silage when fed as the sole source of forage to dry cows with a diet comprising ryegrass silage and a protein supplement.

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.
