When grass silage is available ad libitum, compound feeds depress the intake of silage by cattle. Castle and Watson (1976) and Gill and England (1984) reported that silage intake was not depressed when protein supplements rather than cereals were given to dairy and beef cattle, respectively. The aim of the present trial was to examine protein supplements as alternatives to cereal based compounds to increase the milk yield of dairy cows without reducing silage intake.

Twenty Friesian cows in four pens were arranged in a 4 x 4 Latin square experiment with 4 wk experimental periods to evaluate the effects on feed intake, milk yield and milk composition of treating barley dried distiller’s solubles (DDS) with a formaldehyde reagent, and to compare DDS with rapeseed meal as a protein supplement in dairy cows given a grass silage-based diet. The control diet (C) consisted of grass silage ad libitum fed with 8.5 kg/d of concentrate based on barley, oats and barley fibre (250, 250 and 500 g/kg dry matter (DM)). In three other diets 1.5 kg/d of the basal concentrate was replaced with rapeseed meal (RSM) treated for reduced ruminal degradability, 1.5 kg of untreated DDS (UDDS) or 1.5 kg of DDS treated with formaldehyde reagent at the level of 15 l/t (TDDS). On average, protein supplementation increased silage and total DM intake by approximately 0.5 kg/d (P>0.05). Milk yield (P

Effect Of Feeding

Fish meal supplementation of grass silage diets has increased the daily live-weight gain of growing beef cattle. However, the live weight advantage at turnout has generally been negated after a period of compensatory growth at grass. Hence, protein supplementation may be economically advantageous with cattle being finished out of yards. The purpose of this experiment was to compare the effect of feeding two types of fish meal on the performance of dairy-bred cattle during the finishing winter of an eighteen-month beef system.

The optimization of milk production includes a rational use of forages, respect for the environment and offers the best quality to consumers. Milk production based on grass and forages produces healthier milk and it is widely spread throughout the Atlantic arc to maximize milk yield per hectare. However, the mode of offering the grass can have a major influence on milk composition. The aim of this study was to evaluate the effect of grass supply mode (grazing, zero-grazing or ensiling) on dairy cows’ performance, with particular reference to fatty acids and fat-soluble antioxidants concentration. A three by three Latin square experiment was performed with 18 dairy cows. Experimental treatments consisted of exclusive feeding with grass silage and zero-grazing, both offered ad libitum indoors, or grazing for 24 h. The results showed that grazing cows had a higher dry matter intake and greater milk yield than cows feeding on grass silage and zero-grazing, as well as higher concentrations of protein, lactose, nonfat-solids and urea in milk than housed cows. Milk fat from grazing cows had a higher proportion of unsaturated fatty acids than from cows feeding on grass silage and zero-grazing, with significant differences in the proportion of vaccenic and rumenic acids. The 18:1 trans-11 to 18:1 trans-10 ratio is proposed as biomarker to identify the milk produced from the management system of grazing cattle. Milk from grazing cows had a greater proportion of lutein than cows eating grass silage, with the zero-grazing system having intermediate values. In conclusion, the mode of grass supply affects fatty acid and antioxidant profiles of milk.

There has been much recent debate about the protein requirements of lactatinq dairy cows, and this issue has been heightened by a general reduction in concentrate feeding in response to the imposition of milk quotas. Furthermore, the value of silage as a source of protein has been questioned widely. The objective of the present trial was to determine the effect of increasing supplementary protein on the performance of cows with ad libitum access to high quality grass silage.The trial, using January/February calving British Frieslan cows in second or subsequent lactations, was performed at Ravenscroft Hall Farm, Middlewich, Cheshire. Four groups of 15 cows were offered either 3 or 6 kg/head/day of cereal/soya/fishmeal based compound feeds containing either 214 (L) or 403 (H) g CP/kg DM, and high quality grass silage ad libitum.

In a previous experiment with dairy cows at this Institute, in which fodder beet was included as a third component of the diet along with grass silage and concentrate, fodder beet considerably increased metabolisable energy intake (MEI), but there was little effect on milk yield (unpublished data). The main objectives of the present study were to examine the effects of including fodder beet versus concentrate in a grass silage diet, on milk production, digestibility of nutrients and the utilization of nitrogen (N) and energy at equal ME intake in lactating dairy cattle.

Finishing Beef Cattle

Two randomised-block experiments have been carried out to examine the relative feeding value of wheat and barley as supplements to grass silage for finishing beef cattle. In each experiment unwilted, formic acid-treated silage was offered ad libitum and supplemented with 500 g soyabean meal and 50 g minerals and vitamins to 44 twelve month old bulls for 157 and 172 days in experiments 1 and 2 respectively. In addition 12 animals received 2.5 kg rolled spring barley (LB), 12 received 4.0 kg barley (HB) and 20 received 3.25 kg rolled wheat (W). Silage was offered once daily and concentrates twice daily in two equal meals.Eleven British Friesian bulls and thirty-three bulls which were Friesian x Continental beef breed were used in each experiment. They were initially 402 and 385 kg live weight in experiments 1 and 2 respectively. In both experiments the animals were housed and fed in groups of four in slatted pens. All animals were slaughtered at the end of the experiments to obtain carcass data.

The Difference ◽  
Present Trial

It has often been observed that increasing silage DM through wilting increases DM intake, although digestibility and efficiency of utilisation of nutrients tends to decrease, resulting in poor responses in terms of milk yield. Rapid solubilisation of nutrients in the rumen may give rise to rapid nutrient absorption, activating satiety mechanisms and resulting in shorter meals. In the present trial the difference in DM content of the silages was high (>200g/kg). Supplements based on different energy sources were fed to determine whether synchronisation of release of nutrients from the silage and the supplement modified DM intake and feeding behaviour.

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.

Present Trial

The “low milk fat” syndrome and “off feed” problems have long been associated with the use of rations incorporting a high proportion of starch based concentrate. These problems can be ameliorated by frequent feeding of concentrate, the use of out of parlour feeders or complete diets. Another approach has been to examine alternatives to cereal starch as the major energy source for concentrate supplements. Since few comparisons of concentrates containing a mixture of high quality fibre sources have been reported, the present trial was designed to compare concentrates based on cereal starch with those containing a mixture of high quality fibre sources when given with ad libitum grass silage from calving. An additional aim was to compare individual feeding through Calan Broadbent gates with groups fed forage at a self-feed clamp.
