Production Losses

Many feeding , economic and managemental problems have been observed to be associated with the silage feeding (Wilkinson, 1990) e.g.;1) The high cost of production, losses during storage and damage to the walls and floors of silos.2) Variation in feed characteristics due to multicut.3) Effluent and pollution problems.4) The unpredictable feeding value and tendency to enhance milk fat but not milk protein in lactating animals.All these factors have forced animal scientists to look for suitable alternatives to grass silage . Whole crop cereals have drawn the attention of workers as a substitute for grass silage due to the following advantages ;1) The number of cuts and the harvesting cost can be reduced .2) A high dry matter yield of crop can be obtained with modest application of fertiliser and no effluent problem.3) The early harvesting of the crop gives more time for the entry of the following crop.4) More predictable nutritive value , high grain content ( approaching 50 % ) of the total crop yield .

Calorimetric Studies

A number of equations for predicting methane energy output (CH4-E) in ruminants have been published since 1930. However the data used to develop these equations were collected from diets containing mainly dried or high dry matter (DM) forages, rather than low DM heavily fermented grass silages. Since 1992 a number of calorimetric studies have been carried out with growing and lactating cattle offered grass-silage based diets at the Agricultural Research Institute of Northern Ireland. The objective of the present study was to use these data to develop new relationships between CH4-E output and animal and dietary factors.

1. High and low dry-matter silages were fed to fattening bullocks on the self-feed system giving daily live-weight increases per head per day of 2·6 lb. and 1·7lb. respectively, over a feeding period of 10 weeks.2. Chemical data on the composition of a low dry-matter silage and high dry-matter silage are presented.3. Digestibility studies using sheep were carried out to obtain the starch equivalent values of the two types of silage. The starch equivalent of the high dry-matter silage was 12·4 while that of the low dry-matter silage was 9·9. This difference in starch equivalent explains the extra 0·9 lb. per head per day live-weight increase made by the bullocks on the high dry-matter silage.4. Mineral balances were carried out. The results show that the low dry-matter silage would supply an inadequate amount of calcium for satisfactory production.

Forage Intake

Patterson et al. (2004, 2005) obtained positive intake and milk production responses to the inclusion of maize silage in grass silage-based diets under Northern Ireland conditions. However, fermented whole crop and high dry matter (DM) milled urea/urease-treated whole crop wheats both increased forage intake, but had no significant effect on milk production. The aim of the present study was to further investigate the milk production potential of milled high DM whole crop wheat, in both urea-treated and ‘fermented’ forms, and fermented triticale whole crop, as a partial replacement for grass silage.

Supplementary feeding of grazing dairy cows is often uneconomic, and whilst supplementation with silage (buffer feeding) can be worthwhile, this often leads to a depletion of winter forage stores. In this study, a mixture of brewers grains and treated straw was used as a supplement. Offered as a 1:1 mixture in the dry matter (DM), it is a purchased substitute for grass silage, having a similar cost, and similar metabolisable energy (ME) and crude protein (CP) contents. The high seasonality adjustments to milk price in mid-late season make supplementation potentially worthwhile.Experiments were carried out from April to September in 1988 and 1989, which had moderate and very low rainfall respectively. Each year 20 British Friesian cows which calved December to March (1988 experiment) and February-April (1989) were allocated at random to either treatment B or C. In B, the cows were offered a 1:1 mixture (DM basis) of brewers grains and NaOH treated chopped barley straw for 60 minutes after morning milking. In C, the cows received no supplement. Both groups were fed 1.0 kg/day of concentrates in the milking parlour. Due to the severe drought in 1989, concentrate feeding was increased to 5.0 kg/day for all cows during the last 4 weeks of the experiment. Also, urea-treated whole crop wheat was fed at a level of 2.5 kg DM/day during the last 7 days.

Randomized Experimental Design

The aim of this study was to evaluate the performance of crossbred Holstein × Zebu steers fed on the diets containing sugarcane in natura or ensiled with two levels of concentrate (30% and 70%). A total of 32 males of 394 kg of body weight were used in a completely randomized experimental design with four treatments and seven repetitions. The animals reported a high dry matter intake (DMI) (P < 0.05) when fed on the high concentrate levels. The increase in concentrate levels resulted in an approximately 25% to 60% higher DMI as compared to the lowest level offered by silage-based diets and sugarcane in natura. The highest apparent digestibility coefficients of dry matter were observed in the diets based on sugarcane in natura (P < 0.05). The sugarcane based diets also affected (P > 0.05) the digestibility of organic matter, neutral detergent fiber, crude protein, ether extract, and non-fiber carbohydrates. There were no differences (P > 0.05) between the diets for average daily weight gain, carcass dressing, carcass gain, and feed conversion. The diets based on sugarcane in nature or ensiled with 30% and 70% concentrates do not influence the performance of crossbred Holstein × Zebu cattle.

Ad Libitum

Following weaning at 6–7 mo of age, 36 beef steers were used to determine production responses when grass silage was supplemented with barley or fishmeal. The silage was made from direct-cut, formic- acid-treated grass harvested from a mixed sward and had a high nitrogen content but poor fermentation characteristics. The silage was fed ad libitum for 98 days either alone or supplemented with 500 g fishmeal or 500 g barley per day. Both fishmeal and barley increased total dry matter intake (P < 0.01) by an amount equivalent to the quantity of supplement offered but had no effect on silage intake (P > 0.05). Steers fed the fishmeal grew substantially faster than either the barley (0.53 kg/day) or unsupplemented (0.54 kg/day) groups (P < 0.01). Fishmeal supplementation resulted in a large reduction (35%) in the amount of feed required per kilogram of gain. Key words: Cattle, grass silage, fishmeal, growth
