Eight Finncattle cows were used in two replicated 4x4 Latin squares with 21 -day periods to study the effects of replacing rapeseed cake with linseed cake in proportions of 0, 1/3, 2/3 and 1 (on air dry basis), the total amount of supplement being 1.5 kg/day (on air dry basis). The basal diet consisted of silage fed ad libitum and a 4.5 kg/day (on air dry basis) barley:oats (1:1) mixture. The experimental diets had no effect on feed intake. Effective protein degrability (EPD) determined by the nylon bag method was higher for linseed cake than for rapeseed cake. Milk production decreased linearly (P

Twelve Finnish Ayrshire cows were used in a 4 x 4 Latin square design with 4-week experimental periods to study the effects of replacing increasing amount of barley with wet distiller’s solubles (WDS) on feed intake, milk production, digestibility and blood constituents. The four dietary treatments consisted of grass silage ad libitum and 7.8 kg dry matter (DM)/d of barley, of which 0 (WDSO), 1 (WDS1), 2 (WDS2) and 3 kg DM/d (WDS3) was replaced with WDS. Mainly because of a greater intake of concentrate with WDS containing diets silage DM intake varied quadratically (P

Whole crop wheat (WCW) appears to offer an attractive alternative forage to grass silage for dairy cows, particularly in those areas where maize silage cannot be grown. However in previous feeding trials the inclusion of WCW with grass silage has increased food intake but has not led to a corresponding increase in milk yield (Phipps et al,1993). As part of a programme to try to overcome the low efficiency of diets containing WCW, the present experiment was designed to examine the effects on feed intake and digestibility and milk production of the step-wise replacement of GS by urea-treated WCW.Winter wheat (cv Hussar), harvested at 620g DM/kg fresh weight and preserved with 20 or 40 g urea/kg DM (WCW-2, WCW-4) was compared with first-cut perennial ryegrass silage (GS). Six multiparous Holstein-Friesian cows in mid-lactation were offered six diets over three 4-week periods in an incomplete change-over design. Diets were 6kg DM concentrates daily with forages ad lib. Treatments (DM basis) were GS alone, 2:1 GS:WCW-2 or WCW-4, 1:2 GS: WCW-2 or WCW-4, and WCW-4 alone. Feed intake and milk production were measured in weeks 3 and 4 and digestibility in week 4.

Previous studies (Moorbyet al, 1994) have shown that supplementing grass silage with undegradable protein (UDP) during the dry period can lead to increased yields of milk protein and lactose. These studies have often involved restriction of forage intake through limitation of access time and the feeding of straw. This experiment was conducted to assess the effect of UDP supplementation withad libitumaccess to grass silage as well as the effects of restricting forage intakes by including straw in the diets of dry cows.

Higher dry matter intakes (DMI) have been reported in dairy cows fed maize silage than in dairy cows fed grass silage. The objective of this experiment was to investigate this phenomenon by the measurement of digestibility and the determination of rumen outflow rates for both forages. The response in milk production of late lactation dairy cows to grass or maize silage was also measured.Fourteen late lactation multiparous dairy cows (n = 7) were fed diets containing either grass silage (GS) (DM: 197g/kg; pH: 4.05; NDF: 642g/kg DM) or high starch maize silage (MS) (DM: 339g/kg; pH: 3.94; starch: 360g/kg DM; NDF: 442g/kg DM) ad-libitum plus 4kgs/hd/day of a dairy concentrate (233g CP/kg DM). Urea (460g N/kg DM) was used as a source of degradable protein (10g/kg DM) for the MS diet which also included straw (40g/kg DM). Dietary NDF equalled 542 and 423g/kg DM for the GS and MS diet.

Previous studies have shown a low efficiency of utilisation of urea treated whole crop wheat (UWCW) when offered as the sole forage to dairy cows (Hill and Leaver 1990). The poor efficiency of utilisation of metabolisable energy could possibly be influenced by the level and quality (the balance in QFN, SFN, and UN) of protein intake by the cow.To investigate the effect of level and quality of protein intake on the digestibility of UWCW fed ad libitum to lactating cows, an experiment was carried out using three concentrate sources based upon molassed sugar beet pulp pellets (Diet A), soya bean meal (Diet B) and fishmeal (Diet C). A concurrent experiment was implemented to analyse the degradation characteristics of UWCW using sheep.Six multiparous mid to late lactation Holstein Friesian cows were allocated to two 3x3 latin squares. Each cow was housed in an individual pen and fed UWCW ad libitum once daily and concentrate twice daily. Individual DM intakes of forage, milk production, liveweight and faecal output were estimated for each diet. The degradability trial used the methodology of Paine et al (1982).

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.

Previous studies at this Institute have shown a marked interaction between level of supplementary feeding and protein content in the supplement with dairy cows offered high quality grass silage-based diets. For example, a given milk yield or yield of milk constituents can be obtained by offering supplements of high crude protein (CP) content, eg 340 g CP/kg fresh weight, at much lower levels than would be required with conventional supplements with a CP content of 180 g/kg fresh weight. The aim of the present study was to quantify if. the interrelationships established with high digestibility silages also applied with lower digestibility silage.The experiment was carried out with 60 autumn-calving British Friesian dairy cows. Twenty eight animals were offered early cut silage (E), harvested between 17-19 May, with the remaining thirty two animals offered late cut silage (L) harvested between 2-12 June. Both E and L silages were produced from the same swards and in both cases grass was direct harvested and treated with an inoculant of Lactobacillus plantarum, at the rate of 3.0 litres/t fresh herbage.
