Metabolisable Energy

Maize distillers grains (MDG) is a high quality by-product feed containing 317 g crude protein (CP)/kg DM and 13.5 MJ metabolisable energy/kg DM, and as such is a valuable traceable feed resource. An earlier study conducted at the Centre for Dairy Research (Suttonet al.2000) with cows in late lactation using a total mixed ration (TMR) based on maize silage, compared the protein value of MDG with that of soyabean meal (SB). The study showed that MDG could be used to replace SB on a total nitrogen (TN) basis without effecting feed intake or nutrient digestion in the rumen, or flow of non-ammonia nitrogen to the duodenum. The aim of the current study was to determine the effect of replacing SB with MDG on a TN basis, on DM intake and milk production in high yielding lactating dairy cows.

Soyabean Meal

The complete replacement of soyabean meal by maize distillers grains (MDG) in dairy cow diets had no significant effects on milk production, rumen digestion or the supply of non-ammonia N to the duodenum (Sutton et al., 2000; Phipps et al., 2001). The present experiment was designed to extend this work by examining the response when barley (BDG) or wheat (WDG) distillers grains replaced soyabean meal.

Grazing Dairy Cows

Reducing the time available for grazing from 20h to 5h daily, and replacing this with access to a maize silage/soyabean meal diet indoors had no significant effect on milk yield in spring (Hernandez-Mendo and Leaver, 1999). Grazing conditions in autumn present additional problems of shorter daylength and accumulated herbage contamination. The objectives were to examine the production and behavioural responses of grazing dairy cows to reducing access to grazing and increasing access to a maize silage/soyabean meal diet offered indoors.

AbstractDuring the winter feeding period in organic dairy production systems in the alpine and pre-alpine regions of Austria and its neighboring countries, maize silage is an energy-rich forage that is regularly included in grass-silage-based diets to improve the energy supply of the cows. Italian ryegrass (Lolium multiflorumLam.) is also a high-energy fodder grass popular as forage for dairy cows, but it is rarely cultivated in Austrian organic agriculture. The two crops differ in their cultivation demands and characteristics. Italian ryegrass establishes rapidly and may reduce the risk of soil erosion. Italian ryegrass would be a beneficial addition to crop rotation, which is an essential tool in successful organic farming. In a 15-week feeding trial, Italian ryegrass silage and maize silage were fed to 22 lactating Holstein dairy cows. Organically produced Italian ryegrass silage and maize silage were included at a rate of 40% [of dry matter (DM)] in grass-silage-based mixed basal diets. The mixed basal diets were supplemented with modest amounts of additional concentrates (2.7–3.0 kg DM day−1). Owing to the higher energy content of maize silage as compared to Italian ryegrass silage, the maize diet provided more energy [6.3 MJ net energy for lactation (NEL) kg−1DM] than the ryegrass diet (6.15 MJ NEL kg−1DM). The protein supply of the maize diet and the ryegrass diet was intended to be equal, but in fact the protein content of the maize diet was significantly lower (122 g crude protein kg−1DM) than that of the ryegrass diet (141 g kg−1DM). When the maize diet was fed, feed intake, milk yield and milk protein content were significantly higher as compared to the ryegrass diet. Also, intake of crude protein was significantly lower when feeding the maize diet, and in combination with the higher milk protein yield, this enabled an efficiency of gross nitrogen (N) utilization as high as 0.304. This level of N efficiency can be considered as above average and was significantly and considerably higher than the level of 0.259 observed when the ryegrass diet was fed. Therefore, maize silage upholds its reputation as an ideal energy-rich component in grass-silage-based dairy cow diets.

Molasses has been fed to dairy cows for about a century. Extensive studies have shown that its energy value is worth from 75 to 100% that of maize when up to 10% of molasses is fed in a complete diet and high molasses inclusion in the diet can be detrimental to the responses of the animals. Nevertheless, the maximum inclusion rate of molasses in a diet that cows can tolerate has still been unclear. Few publications are available to describle the responses of cows to very high molasses feeding. This is a question, however, that both farmers and advisers are concious of. The present experiment was designed to evaluate the effects on milk yield and composition, feed intake, liveweight gain and health of lactating cows fed on very high levels of molasses, in comparision with those fed a relatively low level.Fifteen British Friesian late lactation cows (168 ± 6 days calved) all in second lactation or more were randomly allocated to a 3 x 3 changeover experiment with 21 day periods. The cattle were fed individually through Broadbent Calan Gates ad libitum on a complete diet of silage plus a liquid supplement including molaferm 20 (a mixture of 80% cane molasses with 20% condensed molasses solubles supplied by United Molasses Ltd.), soyabean meal and fish meal.

Friesian Cows

Friesian cows (16) in late lactation grazed pure white clover (Trifolium repens cv. Haifa) swards for 32 days in autumn and were supplemented with maize (Zea mays) silage. Four groups of 4 cows were offered either 19 or 39 kg dry matter (DM)/cow.day of white clover with either 0 or 4.4 kg DM/cow.day of maize silage. All cows were individually fed maize silage and grazed the pasture as individual groups according to treatment. When maize silage was fed, total intake increased, this occurring to a greater degree at the low pasture allowance. The level of substitution of silage for pasture was 0.14 and 0.40 kg DM reduction in pasture intake per kg DM of maize silage eaten at the low and high allowances, respectively. At the low pasture allowance, milk yields were 10.1 and 13.7 kg/cow. day when 0 and 4.4 kg DM/cow.day of maize silage were fed, respectively, and were 15.5 and 15.9 kg/cow.day at the high pasture allowance. Liveweight and body condition increased as plane of nutrition increased but there were no effects of feeding on milk fat or protein contents. Feeding maize silage had little effect on any rumen or faecal variable although there was generally less ammonia nitrogen in rumen fluid when cows were supplemented with maize silage.

Grazing Dairy Cows

Efficient conversion of grazed pasture and supplementary feeds into milk is essential to the profitability of dairy farming in southern Australia as costs of production continue to rise. The application of diet formulation approaches to the nutritional management of grazing dairy cows provides unique challenges in predicting the interactions that occur between grazed herbage and supplementary feeds. How feed intake and associative effects between feeds in lactating dairy cows grazing pasture might affect estimated metabolisable energy supplied by the diet are examined. The effects of increasing feed intake in high-producing dairy cows on decreasing the digestibility of energy, and the compensatory effects of reduced methane production, are reviewed. The factors affecting intake of grazing cows and possible effects on digestibility are considered, and include characteristics of the pasture/forage and amounts and forms of concentrates. Estimates of the potential magnitude of negative associative effects in dairy cows have been made using 2 datasets from recent experiments. Finally, the potential importance of understanding and predicting the magnitude of associative effects for efficient pasture-based dairy production is discussed. It is concluded that although associative effects between feeds in grazing dairy cows cannot be predicted with certainty, and although they involve complex interactions among a number of variables, ignoring their occurrence can lead to significant errors in both feed evaluation and ration formulation.

Protein Feed

Maize distillers grains (MDG) are a traceable and valuable energy and protein feed for dairy cows (Owen and Larson, 1991) but little is known about the ability of UK MDG to replace more conventional protein sources, particularly their effects on the supply of protein to the cow. The purpose of the present experiment was to examine the effects of replacing soyabean meal with MDG on digestion in the rumen and flow of protein to the duodenum of lactating dairy cows.

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.
