There is evidence that silage may be utilised more effectively when supplemented with sugar rather than starch (Thomas and Rae, 1988). A trial was made to measure the effect of supplementing silage with a sugar-based feed (molasses) or a starch-based feed (barley), in combination with fish meal, on the performance of young growing cattle.Sixty four castrated male calves (Limousin x Friesian and Hereford x Friesian) initially weighing 129 kg were offered grass silage (DM, 200 g/kg; ME, 10.4 MJ/kg DM; CP, 144 g/kg DM) ad libitum with four dietary supplements.Daily supplementation was as follows:1.0.25 kg white-fish meal2.0.25 kg fish meal plus 0.4 kg molasses3.0.25 kg fish meal plus 0.8 kg molasses4.0.25 kg fish meal plus 0.75 kg bruised barleyThe levels of molasses and barley in Treatments 3 and 4 supplied the same amount of dry matter.

White fish meal and feed additives are used to increase growth rate by young growing cattle in their first winter before being turned out to graze. Some evidence indicates that increased gains may not be retained through the grazing season. A trial was made to measure the effect of fish meal and feed additives, alone or in combination, on performance by young growing cattle during winter and subsequently through the grazing season. Sixty British Friesian castrated male calves were offered silage containing 220g/kg DM ad libitum. There were six dietary supplements.

Voluntary Intake

AbstractSeventy-two, 4-month-old, British Friesian steers were used to investigate the effects of feeding a supplement of fish meal on the voluntary intake and live-weight gain by young growing cattle given a well preserved ryegrass silage. The silage was offered either alone or mixed with 50,100 or 150 g fish meal per kg silage dry matter (DM) and the diets were offered either ad libitum or intakes were restricted to 16, 19 or 22 g dietary DM per kg live weight (LW). Intakes were recorded daily, LW weekly and in vivo apparent digestibility over one 7-day period during the 132-day trial.For animals fed ad libitum, the absolute intake of dietary DM increased linearly with an increase in the level of fish-meal supplementation such that intake when the highest level of fish meal was given was significantly higher (P < 0·01) than when silage was given alone. However, DM intake per unit LW (approx. 24 g DM per kg LW) was not affected significantly (P > 0·05).Inclusion of fish meal in the diet did not affect the apparent digestibility of dietary DM, organic matter, acid-detergent or neutral-detergent fibre (NDF) although there was a trend for slightly higher (P > 0·05) gross energy apparent digestibility when fish meal was given. Increasing the level of feeding reduced NDF digestibility. The coefficients measured at the 22 g and ad libitum levels of intake were lower (P < 0·01 and P < 0·05 respectively) than that measured at the 16 g DM per kg LW level.Animals given silage alone to appetite achieved LW gains of 0·6 kg/day. LW gains increased linearly with increasing level of feeding (P < 0·001) and increasing level offish-meal supplementation (P < 0·001).

Following weaning at 6–7 mo of age, 36 beef steers were used to determine production responses when grass silage was supplemented with barley or fishmeal. The silage was made from direct-cut, formic- acid-treated grass harvested from a mixed sward and had a high nitrogen content but poor fermentation characteristics. The silage was fed ad libitum for 98 days either alone or supplemented with 500 g fishmeal or 500 g barley per day. Both fishmeal and barley increased total dry matter intake (P < 0.01) by an amount equivalent to the quantity of supplement offered but had no effect on silage intake (P > 0.05). Steers fed the fishmeal grew substantially faster than either the barley (0.53 kg/day) or unsupplemented (0.54 kg/day) groups (P < 0.01). Fishmeal supplementation resulted in a large reduction (35%) in the amount of feed required per kilogram of gain. Key words: Cattle, grass silage, fishmeal, growth

The objective of the present experiment was to study the effects of the third-cut grass silage compared with the first- and second-cut silages on intake, performance and carcass characteristics of finishing bulls. A feeding experiment comprised 45 Simmental bulls which were fed a total mixed ration ad libitum. The three dietary treatments included either first-, second- or third-cut grass silage (550 g kg-1 dry matter), rolled barley (435 g kg-1 dry matter) and a mineral-vitamin mixture (15 g kg-1 dry matter). Dry matter and energy intakes and growth rates of the bulls increased when either first- or third-cut silages were used instead of the second-cut silage. This was probably due to differences in digestibility, which was the lowest in the second-cut silage. There were no differences in intake or growth between the first- and third-cut silage-based rations. No significant differences in carcass traits among the feeding treatments were observed.

The objective of this study was to determine the effects of restricted feeding strategies on performance of growing and finishing dairy bulls. The feeding experiment comprised in total 32 Finnish Ayrshire bulls with an initial mean live weight (LW) of 122 kg and age of 114 days. Feeding treatments were silage ad libitum and daily barley allowance of 93 g kg-1 LW0.60 (A); restricted feeding (R) at 0.80 × A; increasing feeding (I) similar to R until LW of 430 kg and thereafter similar to A; and decreasing feeding (D) similar to A until LW of 430 kg and thereafter similar to R. Restricted feeding strategies decreased daily dry matter intake and LW gain and increased the time to reach the target carcass weight (300 kg). Bulls on I exhibited compensatory growth. There were no significant differences in feed efficiency between the treatments. The present experiment indicates that silage intake ad libitum and supplemented with concentrate resulted in most effective beef production.

The effect of replacing wilted grass silage (GS) with pea-barley intercrop silage (PBS) on feed intake, diet digestibility and milk production was studied with 8 multiparous Ayrshire-cows in a replicated 4 × 4 Latin square experiment. Proportion of PBS was 0 (PBS0), 33 (PBS33), 67 (PBS67) or 100 (PBS100) % of silage dry matter (DM). The DM content was 559 and 255 g kg-1 for GS and PBS. Crude protein content was 131 and 170 g kg-1 DM, respectively. Pea-barley silage was more extensively fermented than GS with total fermentation acid content of 120 vs. 12 g kg-1 DM. Silage was fed for ad libitum intake and supplemented with on the average 13 kg concentrate per day. Silage DM intake was 9.2 (PBS0), 9.7 (PBS33), 9.0 (PBS67) and 7.1 (PBS100) kg per day (Pquadr. < 0.05). The energy corrected milk yield [30.3 (PBS0), 29.8 (PBS33), 30.3 (PBS67), 31.3 (PBS100) kg per day] was not significantly affected by the treatment. Milk protein concentration decreased linearly (P < 0.05) in response to feeding PBS. It is concluded that PBS can replace up to two thirds of wilted, moderate quality GS in the feeding of dairy cows because in this experiment pure pea-barley silage reduced silage intake.

Concentrate Level

The response of dairy cows offered grass silage to increases in the level of concentrate supplementation is well documented. However little information exists for dairy sheep. The aim of this trial was to assess the impact of concentrate level on silage dry matter intake, milk production and quality and daily liveweight change in milking ewes.After weaning at 8 weeks, 24 mature Friesland ewes were individually penned. Ewes were offered precision chopped grass silage: (dry matter (DM) 203 g/kg; ph 3.4; ammonia nitrogen 58 g/kg total N; crude protein (CP) 164 g/kg DM; metabolisable energy (ME) 10.9 MJ/kg DM) ad-libitum and concentrate DM (CP 194) g/kg DM; ME 12.8 MJ/kg DM) at daily rates of 0; 0.7, 1.4 and 2.1 kg/day with no more than 0.6 kg per feed. Water was available ad libitum. All animals were milked twice daily through a Fullwood parlour and weighed weekly. Silage was fed daily and refusals removed twice weekly. The experiment lasted 6 weeks and was analysed as a random block design.

AbstractA 28-day experiment with 12 9-month-old cattle (275 kg initial weight, M1), used a 2 × 2 arrangement of treatments to compare the effect of doubling the ad-libitum quantity of long barley straw offered daily (25 or 50 g dry matter (DM) per kg M1) and sex/genotype (Limousin × Friesian steers or Friesian heifers) on intake and selection. All animals received a protein concentrate at 20 g DM per kg M10·75 per day. Prior to the experiment the cattle had grazed for 6 months and were given no pre-experimental change-over period. On day 1 animals were weighed (M1), allocated to treatment and penned individually. Animals were weighed on day 28 (M2). Doubling the amount offered did not affect straw intake (g DM per kg M3 per day; M3 = mean of M1 and M2) during days 22 to 28 (steers: 17·9, 17·2; heifers 14·3, 13·3; s.e. 0·50) but increased the proportion (g DM per kg DM offered) refused (steers: 258, 635; heifers: 412, 721; s.e. 22). During days 22 to 28, at each level of offer (25, 50), refused straw contained (g DM per kg DM) less leaf-plus-sheath than offered straw (25 g steers: 251, 430, s.e. 16·7; 50 g steers: 393, 450, s.e. 19·7; 25 g heifers: 304, 420, s.e. 7·2; 50 g heifers: 405, 446, s.e. 9·6). The sex/genotype effect on intake was attributed to differences in growth potential. Straw intakes increased significantly over the first 14 days, but there were no differences between days 15 to 21 and days 22 to 28. It is concluded that an excess-feeding strategy, involving a doubling of the ad libitum amount of barley straw offered did not result in growing cattle consuming more straw, in contrast to published results with sheep and goats. However, the cattle did show a limited ability to selectively consume leaf-plus-sheath in preference to stem but the improvement in diet digestible organic content (estimated in vitro) was presumably insufficient to stimulate intake.

The objective was to compare the quality of beef from bulls reared in typical Irish indoor systems or in novel grass-based systems. Bulls were assigned to one of the following systems: (a) grass silage plus barley-based concentrate ad libitum (CON); (b) grass silage ad libitum plus 5 kg of concentrate (SC); (c) grazed grass without supplementation (G0); (d) grazed grass plus 0.5 kg of the dietary dry matter intake as concentrate (GC) for (100 days) until slaughter (14.99 months). Carcass characteristics and pH decline were recorded. Longissimus thoracis was collected for analytical and sensory analysis. Lower carcass weight, conformation and fatness scores were found for grazing compared to CON and SC groups. CON bulls had highest intramuscular fat and lighter meat colour compared with grazing bulls. The SC meat (14 days aged) was rated higher for tenderness, texture, flavour and acceptability compared with grazing groups. CON saturated and monounsaturated fatty acid (FA) concentration was highest, conversely, omega-3 FA concentration was higher for GC compared with CON, while no differences were found in polyunsaturated FA. In conclusion, while market fatness specification was not reached by grazed grass treatments, beef eating quality was not detrimentally affected and nutritional quality was improved.
