Avoparcin is a feed antibiotic growth promoter used widely in Europe for broiler chickens, pigs and beef cattle.This paper presents the results of 17 trials conducted in the UK (13), France (3) and Germany (1) to determine the efficacy of avoparcln at levels of 50-150mg per head per day for improving milk production of lactatlng dairy cows.

Crop Maturity

Interest in the use of whole crop cereals as a complementary forage for dairy cows has developed in Europe over the last fifteen years. Initial studies in the UK concluded that near maximum dry matter (DM) yield/ha of whole crop wheat (WCW) occurred in late July/early August when crops contained at least 500 g/kg DM. However, it was noted that when these crops were ensiled they tended to be aerobically unstable. To minimise this problem it was recommended that these crops were preserved with urea rather than being ensiled. Early studies with dairy cows demonstrated that the use of both urea-treated and low DM fermented WCW increased forage intake and milk yield but effects on milk composition were inconsistent (Leaver and Hill, 1992, Phipps et al., 1995). Concern has been expressed that the use of urea in crop preservation was environmentally unacceptable and that high DM fermented WCW offered a possible alternative, which would provide high DM yields/ha of a starch-rich crop. The objective of the current study was to examine the effect of crop maturity on feed intake and milk production of dairy cows. An additional treatment was included to examine the effectiveness of an additive containing L. buchneri designed to improve aerobic stability.

Winter Feeding

As more farmers try to improve the efficiency of their production systems by sourcing safer and cheaper dietary energy and protein from home grown feeds, the importance of cereal-legume bi-crops for winter-feeding of UK livestock may increase. However, little is known about the production, conservation, feeding value and animal performance from such bi-crops in the UK. This study measured the feed intake and milk production from dairy cows fed pea-wheat bi-crop silages.

Present Trial

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.

Ramensin premix was launched onto the UK market in 1978 and became the first non hormonal feed additive for beef cattle.Since that time it has become the most widely used feed additive worldwide and has been shown both by Elanco research and independent research to improve the utilisation of feed by 10%.However, until recently the only method of administration of Romensin was via the feed or incorporated in a feed block.At pasture, if grass is of sufficient quality, it may be unnecessary to feed a supplement thus losing the carrier for Romensin, for a large part of the summer season. During this period of time, the farmer may thus be missing out on an opportunity to achieve the optimum utilisation of feed.As a result of recent research it may now be possible for beef producers to feed Romensin the whole year round. Romensin has been incorporated in a ruminal delivery device containing 16.5 g of monensin sodium designed to delivery 90 - 100 mg of monensin sodium daily over a period of 150 days.

Apparent Conflict

Previous work has indicated that the optimum calving interval for Friesian/Holstein dairy cattle is 365 days. However, a number of studies in the UK, USA and Israel have suggested that this is difficult to achieve with high yielding cows. This apparent conflict prompted ADAS to undertake a national study to investigate the link between milk production, body condition and reproductive performance in high yielding herds.

Plasma Magnesium

In a four year grazing trial with dairy cows the application of 5000 kg lime/ ha (applied in two applications of 2500 kg/ha in winter of the first two years) significantly increased annual pasture production in two of the four years and dairy production in one year. In three of the four years lime significantly increased pasture growth over summer/autumn with concurrent increases in milk production. In the last year of the trial lime had little effect on pasture growth but a relatively large increase in milkfat production resulted. A higher incidence of grass staggers was recorded on the limed farmlets in spring for each of the four years. In the second spring immediately following the second application of lime significant depressions in both pasture and plasma magnesium levels were recorded. By the third spring differences in plasma magnesium levels were negligible but small depressions in herbage magnesium resulting from lime continued to the end of the trial. Lime significantly raised soil pH, Ca and Mg levels but had no effect on either soil K or P. As pH levels of the unlimed paddocks were low (5.2-5.4) in each autumn and soil moisture levels were increased by liming, these factors may suggest possible causes for the seasonality of the pasture response to lime

The data on feeding dairy cows of an energy protein concentrate (EPC) are presented. EPC consists of grain of narrow-leaved lupine, flax, triticale, subjected to heat treatment on a press extruder. The effect of EPC on the change in milk production of cows was determined. The inclusion of extruded concentrate based on lupine grains in the diets of cows made it possible to obtain an increase in milk. Concentrate based on lupine, flax, triticale is equal in biological value to full-fat soy, and at a much lower cost.
