“…However, this latter figure was depressed by the negative SR observed between concentrate levels 1 and 2, namely −0·12 kg silage DM kg −1 fodder beet DM, SR between concentrate levels 2 and 5 being relatively unaffected by the level of concentrate, namely 0·34, 0·21, 0·30 and 0·31 kg silage DM kg −1 fodder beet DM. Nevertheless, these SRs were considerably lower than the mean SR recorded in a number of other studies, namely 0·51 (Sabri and Roberts, 1988), 0·54 (Fisher et al ., 1994) and 0·42 (Phipps et al ., 1995) kg silage DM kg −1 fodder beet DM, and are likely to reflect the low intakes associated with the grass silage on offer in the current study. For example, at a concentrate DM intake of 3·0 kg d −1 , the silage DM intake was only 8·1 kg d −1 .…”

“…(1987), namely 649 g kg −1 DM. Although Sabri and Roberts (1988) suggested that one of the key factors determining the feeding value of fodder beet is the amount of soil contamination, the ash content of the fodder beet in the current study (82 g kg −1 DM) suggested a low level of soil contamination, a reflection of the fodder beet being washed before feeding. Although the ME concentration of the fodder beet offered in this study was not determined, Clark et al .…”

“…However, although the use of maize silage and whole‐crop silage in dairy cow rations has been examined extensively in recent years, fodder beet has received much less attention. The limited work undertaken has indicated that fodder beet, when used as an additional dietary component, normally increases ME intakes, although milk output responses have been variable (Castle et al ., 1963; Roberts, 1987; Sabri and Roberts, 1988; Fisher et al ., 1994). In addition, most studies have examined the response to fodder beet inclusion at a single modest level of concentrate supplementation, and have not examined the response at high levels of supplementation, or identified whether there is an interaction between dietary fodder beet inclusion and level of concentrate supplementation.…”

The effects of level of concentrate supplementation on the response of dairy cows to grass silage‐based diets containing a constant proportion of fodder beet were examined. Forty Holstein‐Friesian dairy cows of mixed parity were used in a 2 × 5 factorial design experiment. Two basal diet types [grass silage alone or grass silage mixed with fodder beet in a 70:30 dry matter (DM) ratio] were offered ad libitum, and the effects of five levels of concentrate supplementation (mean = 3·0, 5·3, 7·5, 9·8 and 12·0 kg DM per cow d−1) were examined. Concentrate supplements were offered via an out‐of‐parlour feeding system. These treatments were examined in a three‐period (period length = 4 weeks) partially balanced changeover design experiment. Fodder beet inclusion had no significant effect on the estimated metabolizable energy (ME) concentration of the ration (P > 0·001). Total DM intake, estimated ME intake, milk yield, milk protein content and milk energy output all showed significant linear increases with increasing level of concentrate inclusion (P < 0·001) while, in addition, milk yield and milk energy output exhibited a significant quadratic increase (P < 0·01). The inclusion of fodder beet in the diet reduced silage DM intake (P < 0·01) but resulted in an increase in total DM intake and estimated ME intake (P < 0·001). However, inclusion of fodder beet had no significant effect on milk yield (P > 0·05), while increasing milk protein content and milk energy output (P ≤ 0·05). Milk energy output, as a proportion of estimated ME intake, was significantly (P < 0·001) reduced by fodder beet inclusion (0·44 vs. 0·38). Despite large increases in estimated ME intake with the inclusion of fodder beet at all levels of concentrate supplementation, milk energy output responses were small, resulting in an overall reduction in the efficiency of conversion of ME intake into milk energy output. An increased partitioning of dietary ME intake to tissue gain is suggested as the most likely explanation for the observations made.

“…Rations were designed to increase milk protein content and forage intake. Fodder beet and wholecrop wheat are regarded as suitable forages to achieve these objectives (Sabri & Roberts, 1988;Hameleers, 1998). Wheat was chosen in preference to barley for this system, since, with a low nitrogen fertilizer input, it would be higher yielding.…”

In view of recent concerns over the effects of nitrogenous compounds on the atmosphere and ground water, reduction of nitrogen losses from agricultural systems has become of interest. A systems study was designed to improve the efficiency of use of nitrogen (N in milk!N in inputs) (NE) of two dairy systems, one relying on N fixation by white clover (GC) and one using chemical mineral N fertilizer (GN). Management alterations included reduction in stocking rate, growing alternative forage crops and reduction in fertilizer inputs (for GN). Farm gate N balances indicated that the NE of GC was increased from 23 to 34%, and of GN from 13 to 21%. N surplus was reduced from 184 to 90 kg N ha-1 in GC and from 369 to 258 kg N ha-1 in GN. System GC was most affected by a reduction in feed inputs, and system GN by a reduction in fertilizer inputs. Farm gate N balances provide a straight forward method of 'benchmarking' to assess performance of whole farm systems in terms of potential environmental load. Although the contribution of N inputs by fixation cannot be measured directly on a farm scale, it is considered important that account is taken of this input to biological systems using estimates based on the results of research.

In a feeding experiment 3 x 12 dairy cows (German Simmental x Red Holstein Friesian) were used to investigate the influence of different amounts of fodder beets on feed intake, milk yield and milk composition. The fodder beets (variety Kyros) were fed in exchange for concentrate. The amounts of fodder beets were either 22 kg cow-1 d-1 or 44 kg cow-1 d-1 or zero (control group). All groups received 4 kg hay cow-1 d-1, grass silage ad libitum, and concentrate corresponding to the milk yield. In order to balance the rations the concentrate was either rich in protein or rich in energy. Feeding 22 kg or 44 kg fodder beets increased forage intake (including fodder beets) significantly. However, the total feed intake diminished on average from 18.3 kg DM cow-1 d-1 (control group) to 17.2 kg DM cow-1 d-1 (fodder beet groups). In each treatment the intake of hay was 3.3 kg DM cow-1 d-1. However, the intake of grass silage offered ad libitum was significantly suppressed by the fodder beets. Considering the different amounts of concentrate the quantity of suppression of grass silage by feeding fodder beets was calculated at -0.8 kg DM of grass silage per kg DM of fodder beet intake. The milk yield decreased linearly with increasing fodder beets on average up to 4 kg cow-1 d-1. However, the milk composition was scarcely influenced. The fat content increased a little, the mean alterations of the protein and lactose content were below 0.1 percentage points. Therefore, the change in daily excretion of milk fat, protein or lactose were similar to the change in milk yield. In conclusion, feeding fodder beets in combination to grass silage causes a positive effect on forage intake (including fodder beets). However, the amount of concentrate should not be reduced equivalently to the energy contents of the added fodder beets.
