There is increasing interest in the addition of dry feed materials to grass at ensiling, primarily as a means of reducing effluent production, although other benefits claimed include improvements in silage fermentation and animal performance.A large number of studies have demonstrated lower effluent outputs and improvements in silage fermentation due to the inclusion of materials such as cereals and sugar beet pulp, although experiments examining the effects on animal performance are limited.Recently, Jones and Jones (1988) observed higher liveweight gains from beef steers fed silage produced by ensiling grass with molassed beet feed compared to animals fed the same quantity of beet feed mixed with silage produced from untreated grass at the point of feeding. The major objectives of the present study were to evaluate the possible use of sugar beet pulp as an absorbent material in silage making and to examine the effects of its inclusion with grass at ensiling on animal performance.

AbstractAlthough levels of concentrate supplementation are generally lower in organic as compared with conventional dairy cows, forage-only (FO) diets are not very common in organic dairy cows because of the resulting limited dry matter intake (DMI) and lower milk production. However, from the perspective of net food production, FO diets or forage diets supplemented only with by-products from the food processing industry, offer considerable potential because they do not compete with humans for food. The aim of the present study was therefore to investigate the effects of adding a mixture of wheat bran and dried sugar beet pulp [0.56:0.44 on a dry matter (DM) basis] to a FO diet on DMI, milk production, chewing activity and production efficiency. Seventeen multiparous and three primiparous mid-lactation Holstein cows were randomly assigned to one of two treatments, receiving either a FO mixture with hay and grass silage in equal proportions (FO) or the same forage mixture supplemented with a mixture of wheat bran and dried sugar beet pulp at a rate of 25% of dietary DM (25%BP). The experiment was conducted in a change-over design with two experimental periods of 7 and 6 weeks, respectively. Overall, feeding the 25%BP diet increased DMI and energy-corrected milk (ECM) yield by 1.8 kg d−1 as compared with cows fed FO. Feed conversion efficiency (kg ECM per kg DMI) and energy efficiency (kg ECM per 10 MJ net energy for lactation intake) were higher in FO, but cows fed FO were in a slightly negative energy balance and also tended to have a higher mobilization of body tissues as compared with cows fed 25%BP. In comparison with FO, cows receiving 25%BP showed less chewing activity per kg DMI or per kg neutral detergent fiber ingested. In conclusion, results from this feeding trial showed that adding wheat bran and dried sugar beet pulp to a FO diet increased DMI and milk yield and improved the energy balance when compared with a FO diet, although the magnitude of the milk yield response was lower than expected.

Incorparating dry feed materials such as molassed sugar beet pulp with grass at ensiling has been shown to reduce effluent production (Jones et al. 1990) and improve silage fermentation (Offer and Al-Rwidah,1989). Jones and Jones (1988) observed higher liveweight gains in beef steers fed silage produced by ensiling grass with molassed sugarbeet pulp compared to animals fed the same quantity of beet pulp, mixed with silage produced from untreated grass, at the point of feeding. Ferris and Mayne (1990) observed that milk output per unit of grass ensiled was similar for cows offered diets in which a given quantity of sugar beet pulp was either included with grass at eniling or offered as a supplement with untreated grass silage.The objective of the present study was to examine the possible use of molassed sugar beet pulp fed either separately or ensiled with grass at the time of silage making on ewe and lamb performance.

SummaryA cubed molassed sugar-beet product with added urea, dicalcium phosphate, trace elements and vitamins was prepared containing 17% crude protein and up to 0·53% P. The product was evaluated in 3 changeover trials with lactating cows and the treatments involved comparisons with a low protein (10%) concentrate and one supplemented with groundnut plus cottonseed meals. When the product was included at 35–62% in milk production diets the mean daily yield of about 15 kg was about 0·5kg less than when full supplementation was as vegetable protein. This was considered more likely to be associated with inefficient utilization of urea rather than because of an energy difference between molassed sugar-beet pulp and barley.

AbstractTwo groups of grazing lactating dairy cows (no. = 10) were offered straw/sugar-beet pulp mixtures of different straw and sugar-beet pulp content. The low straw mixture (LS) contained 310, 592, 65, 9 and 24 g/kg dry matter (DM) of barley straw, sugar-beet pulp, cane molasses, urea and minerals respectively. The high straw mixture (HS) contained 540, 359, 65, 12 and 24 g/kg DM of these ingredients. This resulted in metabolizable energy and DM degradability values of 10·4 and 8·4 MJ/kg DM and 0·48 and 0·42 for mixture LS and HS, respectively. In experiment 1, the mixtures were offered for 1 h after each milking while in experiment 2 the amount of LS available was restricted to the intake of the HS mixture. The animals continuously grazed a perennial ryegrass sward with sward height maintained at 7·5 and 6·9 cm respectively for experiment 1 and 2. Forage intakes in both experiments were measured using the n-alkane technique. In experiment 1, intakes of the forage supplement were 5·3 and 2·3 kg DM per day (s.e.d. = 0·51, P < 0·001), while herbage intake was 11·5 and 14·5 kg DM per day (s.e.d. = 0·77, P = 0·004), resulting in total forage intakes of 16·9 and 16·7 kg DM per day for treatments LS and HS respectively. No significant differences in terms of time spent grazing, ruminating and eating forage supplement were observed. No significant differences in terms of animal performance were observed. In experiment 2 intakes of the forage supplements were 2·8 kg DM per day for both treatments while herbage intake was 13·0 and 13·2 kg DM per day (s.e.d. = 110) resulting in total daily intakes of 15·8 and 16·0 kg DM (s.e.d. = 1·24) for treatment LS and HS, respectively. No significant differences in terms of grazing time, rumination time or animal performance were detected. It was concluded that under conditions when herbage was readily available, higher amounts of high energy/high degradability forage supplement were consumed than of low energy low degradability forage supplements. However, total dry matter intakes were equal. Intake from forage supplements seem to be affected by short-term fill effects in this situation.

ABSTRACTSugar-beet pulp as normally produced in Great Britain contains about 400 g molasses per kg dry matter (DM). It has been demonstrated that either a reduction in the amount or even the full removal of the molasses did not affect the yield or composition of the milk of cows (e.g. Ronning and Bath, 1962; Hemingway, Parkins and Fraser, 1986). The dried, shredded pulp without molasses was, however, generally less palatable.

There is increasing interest in the addition of dry feed materials to grass at ensiling, primarily as a means of reducing effluent production although other benefits claimed include improvements in silage fermentation and animal performance. The objective of the present study was to examine the possible use of molassed sugar beet pulp fed either separately or ensiled with grass at the time of silage making on ewe and lamb performance, and with or without protein supplementation.Grass from a primary growth of perennial ryegrass with dry matter, water soluble carbohydrate and crude protein contents of 13.2%, 24 g/kg and 106 g/kg DM respectively was mowed on June 2nd and was picked up using a precision chop harvester on the 4th and 5th of June. The weather during this period was extremely unfavourable for good silage making. There were 7.5, 1.5 and 2.8 mm of rainfall on the 3rd, 4th and 5th of June. The temperatures (0 C) on these days were: 2nd June - 12.9: 3rd -10.6: 4th - 10.7. There was no bright sunshine hours on either the 3rd or 5th of June and only 2.1 hours on June 4th. Two treatments were imposed (i) formic acid (2.5 litres/t) applied in the field via the forage harvester (GS) (ii) molassed sugar beet pulp (MSBP)(50 kg/t) applied by hand in the silo on top of each load of grass(GSP).The two silos were filled .consolidated and sealed within 24 hours.

SUMMARYTwo 16-week experiments with lactating Ayrshire cows were conducted to study the effect on milk production of replacing barley with dried molassed sugar-beet pulp on an equal dry-matter basis. The cows on all treatments received equal weights of hay, groundnut cake and minerals but the contents of barley and of sugar-beet pulp each varied from 0 to 80% in the different concentrate mixtures. The total daily intake of dry matter expressed as a percentage of live weight averaged 2·64 and 2·72 in the two experiments.The average yield of milk in the two experiments was 18·8 kg/cow per day, and, within each experiment, the mean yields of milk and the contents of solids-not-fat and crude protein were not significantly different on the contrasting feeding treatments. The intake of water was significantly increased as the dried beet pulp replaced the barley but no major changes occurred in the proportions of V.F.A.S in the rumen liquor.It is concluded that barley and dried molassed sugar-beet pulp had the same feeding value on a dry-matter basis when used in the production ration of milking cows. It is suggested that for most purposes barley and dried sugar-beet pulp are interchangeable on an equal weight basis, but for more precise feeding the two feeds should replace each other on an equal dry-weight basis.

Feeding Value

Silage effluent represents a potential pollutant and a loss of ensiled nutrients. An absorbent provides the possibility of absorbing effluent, aiding fermentation and increasing the feeding value of the silage. Sugar beet pulp (SBP) nuts and rolled barley (RB) were evaluated as absorbents with direct cut grass silage.Perennial ryegrass swards of 222 g/kg average dry matter were direct cut between 10 and 12 July 1989. Grass was ensiled with the following rates of absorbent per tonne of fresh material:1.20 kg SBP (S20).2.40 kg SBP (S40).3.40 kg RB (B40).4.Untreated (U).Production of silage effluent was measured with a tippler mechanism attached to an electronic logger and recorded daily until 22 September. The silages were individually fed through Calan Broadbent doors to 48 x 12 month old Friesian steers between 24 October and 19 December.

AbstractTwenty-four Friesian dairy cows were divided into two groups of 12 between 12 and 18 weeks prior to calving and fed to achieve condition scores at calving of 3·2 (F) or 2·3 (T). For the first 11 weeks of lactation, six cows from each group (H) were given daily 9 kg of a high-fat compound (acid ether extract (AEE) 96 g/kg dry matter (DM)), 3 kg molassed sugar-beet pulp and hay ad libitum. The other six cows in each group (L) were given 10 kg of a low-fat compound (AEE 29 g/kg DM), 2 kg sugar-beet pulp and hay ad libitum. Allowances of compound and sugar-beet pulp were designed to provide equal amounts of energy, neutral-detergent fibre and protein. The fat source used in compound H was a calcium salt of palm acid oil (Megalac®).DM intake was not affected by treatment but fat intake was significantly higher on diet H (P < 0·001). Group TH had higher intakes of digestible energy (DE) than group FH (249 v. 229 MJ/day; P < 0·05), but condition at calving did not affect DE intake with diet L (FL = 230, TL = 233 MJ/day). Milk yield was not significantly affected by treatment, although cows in group TL tended to yield less milk than other groups (28·3, 27·3, 28·0 and 24·3 kg/day for FH, FL, TH and TL respectively). The concentration of milk fat was higher and of milk protein lower with diet H compared with diet L (milk fat 48·1, 42·2, 42·9 and 39·6; milk protein 28·0, 31·0, 28·4 and 30·5 g/kg for FH, FL, TH and TL respectively). Loss of condition score was greater for cows in group F (0·65 units) than for those in group T (0·04 units). Within group F, loss of condition tended to be greater with diet L.It is concluded that the increased intake of fat with diet H tended to decrease loss of condition in cows that were fat at calving but increase milk yield in cows that were thin at calving. It also tended to increase milk fat concentration but decreased milk protein concentration.
