Studies with beef cattle (Kennedy and Carson, 1991) and dairy cattle (Chamberlain et al, 1990) have shown responses in dry matter intake of silage and animal performance through applying Maxgrass silage additive to unwilted herbage ensiled in clamps. Maxgrass (BP Chemicals Ltd) contains (weight/volume) 68% ammonium hexamethanoate, 11% ammonium hexapropanoate and 2% octanoic acid.Research at Aberdeen has shown the benefits of using both inoculant (Weddell, 1990a) and formic acid based (Weddell, 1990b) additives on big bale silage which now constitutes around 15% of the total silage dry matter ensiled in the UK. The present study compared the effects on silage composition, animal performance and storage losses of Maxgrass treated with untreated big bale silage.Second cut perennial ryegrass herbage was wilted to a mean DM content of 230 g/kg then baled by fixed chamber baler. Mean water soluble carbohydrate was 100 g/kg DM. Alternate groups of six bales were left untreated or treated with Maxgrass silage additive at 7.4 1/tonne wilted grass.

Elevated water-soluble carbohydrate (WSC) concentration in the diet may affect rumen fermentation and consequently reduce methane (CH4) emissions. The objective of the present study was to determine CH4 emissions from male sheep (8 per treatment) in respiration chambers for 48 h and fed either a conventional diploid (CRG), a high-sugar diploid (HSG) or a tetraploid (TRG) perennial ryegrass cultivar, each offered at 0.7 or 1.0 kg dry matter (DM)/day during periods in early spring 2013 (P1), early autumn 2014 (P2) and late spring 2014 (P3). There was a significant (P < 0.001) interaction between cultivar and period for CH4 yield (g/kg DM intake). In P1 yield was 9% lower (P = 0.007) for sheep fed HSG than for sheep fed CRG or TRG, in P2 yield was 16% lower (P < 0.001) for sheep fed TRG than that for sheep fed CRG or HSG, and in P3 yield was 15% lower (P < 0.001) for sheep fed TRG than that for sheep fed CRG, with HSG-fed sheep being intermediate and not significantly different from either CRG or TRG. Despite there being a cultivar × period interaction, overall, CH4 yield was lower for sheep fed HSG or TRG than for sheep fed CRG (P < 0.001). There were no cultivar × level of feed offer interactions and, overall, yield of CH4 was 9% higher (P = 0.003) for sheep offered 0.7 than for sheep offered 1.0 kg DM/day. In each period, one or other of the high-WSC diploid (HSG) or tetraploid cultivars (TRG) gave lower CH4 yields than did the control diploid (CRG), suggesting that CH4 yield is reduced by characteristics of these cultivars. However, the effect was not consistently associated with either cultivar and could not be attributed to higher forage water-soluble carbohydrate concentrations.

Extension growth of the chlorophyll-containing roots of Hydrocharis morsusranae was inhibited by 0.5 p.p.m. of 3-(4-chlorophenyl)-1,1-dimethylurea (monuron) whereas concentrations close to the water saturation point of 230 p.p.m. were required to inhibit extension growth of the non-chlorophyll-containing attached roots of Zea mays and Phleum pratense and the detached roots of Pisum sativum.A total of 15–20 μg of monuron per gram fresh leaf applied through the cut petiole of detached primary leaves of Phaseolus vulgaris inhibited the increase of dry matter by 90% and suppressed transpiration 40–50%. Internal concentrations of 1–2 μg/g of monuron produced simultaneous enhancement of dry matter increase and of transpiration but concentrations of 5–10 μg/g produced a suppression of dry matter increase concurrently with an enhancement of transpiration. Age of leaf and the time of year in which the plants were grown altered the critical internal concentration levels required to affect dry matter increase and transpiration.Analysis of detached leaves treated with 15–20 μg/g monuron indicated a marked suppression of the formation of non-water-soluble carbohydrate, a slight suppression of the formation of water-soluble nitrogen, but little or no effect on water-soluble carbohydrate or on non-water-soluble nitrogen.In detached leaves o-phenanthroline, 3-phenyl-1,1-dimethylurea, and 3-(3,4-dichlorophenyl)-1,1-dimethylurea resembled monuron closely in symptom development and in their effect on dry matter production and transpiration. Iodoacetamide, 2,4-dinitrophenol, and 8-hydroxyquinoline each produced some effects similar to monuron but differed from it in certain respects; Thiourea, sodium diethyldithiocarbamate, sodium fluoracetate, ethyl-NN-diphenylcarbamate, and hydroxylamine hydrochloride were without noticeable effect.

The Relationship

The dry matter (DM) and water soluble carbohydrate (WSC) concentrations of forage are the main characteristics influencing the course of silage fermentation. Knowledge of these parameters would enable decisions to be made both on the need for additive and the type of additive likely to be most effective. Moreover, the degree of wilt could also be followed in wilted crops. The present study was directed to assessing the relationship between the composition of the crop and the volume and composition of the expressed juice. The ultimate objective was the development of on-farm methodology for predicting the ensiling characteristics of crops.

Sweet sorghum (Sorghum bicolor) was grown in an irrigated field trial at Richmond, New South Wales, to determine the effects of row spacing (30, 75, and 105 cm) and plant population (8 and 16 plants/m2) on yields of water soluble carbohydrate (WSC) and dry matter. For both plant populations, narrow row spacing resulted in significantly greater dry matter and WSC yield, especially at seed maturity. Total dry matter and WSC yield also increased with increased plant population from 8 to 16 plants/m2. Much of the WSC yield advantage of reduced row spacing was attributed to greater photosynthetic productivity before anthesis, which resulted in higher WSC yield at anthesis and the production of taller, thicker stems, the volume of which was closely related to post-anthesis WSC accumulation

Water Soluble Carbohydrate

Preservation of forage with silage method has been widely practiced by farmers, one of the factors that influence the success of making silage is the addition of additives, such as molasses. However, molasses is not available in all regions. For that we need a material that can be an alternative substitute for silage, namely granulated sugar, besides having nutritional value that is almost the same as molasses, sugar also contains water soluble carbohydrate (WSC) which is easily utilized by lactic acid bacteria as an energy source during the ensilage process. This study aims to determine the effect of molasses and sugar levels on pH values and dry matter of elephant grass silage. The study used a completely randomized design (CRD) with 5 treatments and 3 replications, namely P1: control, P2: Molases 4%, P3: Sugar 4%, P4: Molases 6% and P5: 6% sugar. So that the total sample unit is 15 units and one unit of fresh material samples. Samples were analyzed in the laboratory to determine the pH value and dry matter of silage. The results showed that the administration of sugar additives at the level of 4% in silage had the same quality as silage which was given molasses at the level of 4%. However, at the level of 6% silage which is given molasses it has better quality than silage which is given sugar. This shows that granulated sugar can be used as an alternative to molasses in making silage.

Neutral detergent fibre (NDF), acid detergent fibre (ADF) and water soluble carbohydrate (WSC) levels were determined on 80 samples of known apparent dry matter digestibility (DMD) and voluntary intake of dry matter (DMI). The pastures consisted of regrowths of six species: Trifolium repens (white clover cv. Grasslands Huia), Lolium perenne x L. multiflorum (short rotation ryegrass c.v Grasslands Manawa), Lolium perenne (long rotation ryegrass cv. Grasslands Ariki), Lolium perenne (perennial ryegrass cv. Tasmania No. I), Dactylis glomerata (cocksfoot cv. Currie) and Dactylis glomerata (cocksfoot cv. Grasslands Apanui), cut eight times between May 1969 and August 1970. Overall, white clover had a lower NDF and a lower WSC content than the ryegrasses but both groups had similar ADF contents. Cocksfoots had higher NDF and ADF, and lower WSC contents than the ryegrasses. NDF and ADF could be used to predict the DMD of all species in all seasons with residual standard deviations (RSD) of 3.0 and 3.2 DMD units (per cent) respectively. No significant relations (P < 0.05) were present between DMD and WSC content. Seasonal differences were present in the relations between DMI and chemical composition. The RSD of the overall regressions of intake with NDF, ADF, and WSC contents were 9.3, 9.4, and 8.9 DMI units (g/day/kg0.75) respectively. Within seasons, DMI was best predicted by regressions with detergent fibre content and here the RSD had a range of 3.4 to 5.2 DMI units. Within species over all seasons, DMI was predicted best by regressions with WSC content and the RSD had a range of 5.7 to 7.9 DMI units. The usefulness of the chemical composition measurements in explaining the reason for the low intakes, previously found with winter pasture, is discussed.

Italian ryegrasses, cultivars Barmultra and Lemtal, and Westerwolds ryegrasses, cultivars Barspectra, Merwester and Promenade, (Lolium multiflorum Lam.) were harvested as first- and second-cut herbages and compared for yield, leafiness and water-soluble carbohydrate content during the 2-yr study. These herbages were conserved as silages and compared for chemical composition and for intake, digestibility, and total-N retention in sheep. First-cut ryegrass yielded more dry matter than second-cut ryegrass (3.3 vs. 2.6 t ha−1). First-cut ryegrass silages contained less dry matter and NDF, and sheep consumed less, but digested better and retained less total-N in comparison with second-cut ryegrass silage. Italian ryegrasses yielded less dry matter, were more leafy, contained less ADF, and were better digested compared with the Westerwolds ryegrasses. The herbage content of water-soluble-N, and the ratio of ammonium-N to total-N in silage were not different between the ryegrasses. Italian Barmultra was more leafy than Lemtal cultivar but no other significant differences were measured between these cultivars. Westerwolds Merwester yielded more dry matter, was less leafy, contained more NDF and ADF, and had lower voluntary intake, digestibility, and its total-N was less retained in sheep as compared with the Barspectra or Promenade Westerwolds ryegrass. Italian ryegrasses were superior in composition, voluntary intake, and digestibility to Westerwolds, but the latter were superior on the basis of yielding ability and efficiency of total-N utilization in sheep.Key words: Silage, ryegrass, intake, digestion, composition, Nitrogen retention
