Basal Ration

Beef steers of liveweight (LW) 277kg were offered a basal ration of hay, untreated silage, or enzyme-treated silage supplemented with a barley + lupin + mineral (67:30: 3) concentrate at 0.5, 1.0, and 1.5% of LW for a maximum of 120 days. The quality of silage was significantly (P<0.001) higher than hay (in vitro DMD: 673.0 v. 609.2 g/kg DM), primarily due to a shorter ungrazed growing period before harvest. The enzyme additive did not improve the quality of the silage compared with untreated silage, as indicated by pH, lactic acid, and in vitro dry matter digestibility. Intake of silage was significantly (P<0.001) higher than that of hay (4.10 v. 3.68 kg DM/day). Final LW and LW gain of cattle fed silage were significantly (P<0.001) higher than of those fed hay (370 v. 345 kg; 1.03 v. 0.61 kg/day). As the level of grain increased there was a significant (P<0.001) increase in daily LW gain across all diets (0.63, 0.94, and 1.10 kg/day at 0.5, 1.0, and 1.5%). At slaughter, carcass weight was significantly (P<0.001) higher for cattle fed silage-based diets (207 v. 194 kg). When cattle were fed a higher quality conserved forage (silage), less grain (1.5 v. 4.5 kg/day) was required to achieve similar LW than with more traditional, forage (hay) based diets.

Whole plants were sampled every 10 or 11 days from field-grown P. americanum X P. purpureum canopies which were cut at intervals of 3 or 6 weeks. Tillers of varying lengths were analysed for in vitro dry matter digestibility (IVDMD). During the growing period, average whole tiller digestibility decreased, as did differences between tillers of different lengths. In 42-day-old herbage, no difference in IVDMD was found between 10 and 70 cm tillers. The decline in digestibility with time was attributed to (1) the appearance of tall tillers and (2) the detrimental effects of low light intensities on tillers growing deep in the canopy. Results suggested that it is doubtful whether tiller length or other morphological or physiological traits can be used to predict herbage digestibility, and that in breeding for better digestibility selection for stem digestibility per se should be more promising than selection for reduced stem growth.

Cutting Height

The trial was conducted at the Centro de Producción Agrícola of ICfA in Cuyuta, Escuintla-Guatemala in order to generate information on the yield and quality of edible mulberry (Morus sp.) roughage treatments consisted of three harvest frequencies (6; 9 and 12 weeks and three fertilization levels of nitrogen (0.40 and 80 kg/ha). A complete randomized block experimental design, with a factorial arrangement (3x3) was used. The cutting height was 0.3 m above the ground level with two sequencies: from August 2nd to September 13 th and from September 13th to December 6th, 1990. In both cases, the 12 week frequency cutting and 80 kg of N were superior to the others (P<=0.01), yielding 6.87 and 6.15 t/ha of dry matter respectively. The yields at 9 weeks were statistically higher than those at 6 weeks. The highest protein percentage of the whole plant, leaves and stalks were produced at 6 weeks. The dry matter digestibility values in vitro showed little variability among treatments, with averages for whole plants, leaves and stalks of 65, 91 and 41 %, respectively. The preceeding data suggests that the mulberry has an excellent potential as a balanced supplement (protein and energy) for dual purpose cattle on the Southern coast of Guatemala.

Abstract: The objective of this work was to evaluate the effects of re-ensiling and bacterial inoculation on the quality of corn silage. The experiment was carried out in a 2x2 factorial design with or without inoculant (association of Lactobacillus plantarum and Propionibacterium acidipropionici), and with re-ensiling after 36 hours of aerobic exposure or only ensiling of the whole plant of 'BRS 1055' corn. The fermentative quality, nutritional parameters, dry matter losses, aerobic stability, and microbiological counts of silages were evaluated. Re-ensiling caused an increase of pH and in acetic acid and propionic acid concentrations, as well as in the dry matter (DM), crude protein, neutral detergent fiber, and neutral detergent fiber crude protein contents. Conversely, there was a reduction in the nonfiber carbohydrates concentration and in in vitro dry matter digestibility for the re-ensiled material. All changes were explained by the higher-effluent production and DM loss of re-ensiled material that was subjected to two compactions. Microbiology was not altered by the treatments. The use of inoculant altered ash content, but it did not influence other parameters. In contrast, re-ensiling after 36 hours of aerobic exposure caused a reduction in the nutritive value of corn silage and accentuated the DM losses.

Farm Scale

That alkali treatments can improve the nutritional quality of poor quality roughages has long been established (Sundstol and Owen, 1984). However, their effectiveness is limited by their potential hazards to the animals and mankind. Alkaline hydrogen peroxide (AHP) has recently emerged as a possible substitute (Gould, 1985) but its farm scale application is limited by the need for high amounts of chemicals and water. Lack of any information regarding its effectiveness over NaOH alone is another factor which requires further investigation. The present study was, therefore, planned to assess the effectiveness of pH-regulated (11.5±0.2) H2O2 (AHP) in improving the in vitro dry matter digestibility (IVDMD) of wheat straw (WS, Avalon) under different laboratory conditions. The possibility of using CaO on its own or to regulate pH for AHP was also tested.

SUMMARYPost-anthesis trends in yield and forage quality of dry matter in components of the maize shoot were studied in experiments with barren and fertile plants grown at 10 plants/m2. In fertile plants, which had a maximum shoot DW 6 or 7% higher than barren ones, the stems (including leaf sheaths) yielded 5 t/ha (42% shoot DW) 30 days after flowering, declining to 3·5 t/ha (26% DW) at final harvest 60 days later. During this period the ear increased by more than 4 t/ha, from 23 to 50% of shoot DW, whereas in barren plants there was little change in DM distribution, with the stem representing about 48% shoot DW, leaf and husk together 40–45% and the ear (rachis only) less than 10%. DM percentage of shoots was similar in barren and fertile plants until maximum DW was attained about 60 days after flowering, after which fertile plants dried more rapidly. In vitro dry matter digestibility was as high in barren as in fertile plants, and the analytical data on forage quality do not suggest that it was positively associated with grain content.

Dry Tropics

In the semi-arid tropics, accumulated shed leaf of certain pasture legumes can provide highly nutritious feed for cattle in the dry season. Previous papers in this series have dealt with the fungal spoilage of leaf of Caribbean stylo in response to dew and unseasonal rainfall and the threat to acceptability by cattle. This paper focuses on the effects of varying degrees of moulding and leaching on dry matter digestibility of leaf of this legume. Uniform leaf material of high digestibility was exposed at six locations during the dry season and samples retrieved at 4-weekly intervals. From initial values of 75%. in vitro digestibility dropped to as low as 50%. Degree of moulding, as indicated by a quantitative index of discoloration, accounted for about 80�/o of loss. Moulding was much more important than leaching. This latter finding in the winter-dry tropics contrasts with previous findings in the summer-dry Mediterranean climate.

The objective of this study was to evaluate dry mass production, fermentative parameters and chemical and bromatological composition of sunflower silage and Paiaguas palisadegrass silage in monocropped and intercropping in different forage systems. The experimental design consisted of randomized blocks, with four replicates. The treatments consisted of silage forage systems: sunflower monocropped; Paiaguas palisadegrass monocropped; sunflower row-intercropped with Paiaguas palisadegrass; sunflower inter-row intercropped with Paiaguas palisadegrass; and sunflower oversown and intercropped with Paiaguas palisadegrass, totalizing 20 experimental silos. Sunflower and Paiaguas palisadegrass were harvested at 110 days after planting at 20 cm from the soil for silage, using brush cutter. The silos were opened after 53 days of fermentation. The rows and inter-row intercropped systems contributed to increase the mass production of the ensiled material. The monocropped sunflower silage had higher values of pH, ethereal extract and acid detergent fiber and lower values of titratable acidity and dry matter, crude protein, neutral detergent fiber and in vitro dry matter digestibility values. The silages of the sunflower intercropped with Paiaguas palisadegrass in forage systems of crop-livestock integration presented better fermentative and bromatological characteristics, guaranteeing an adequate fermentative process and nutritional quality. In this way, the intercropping of these two forages potentiates the production of silage for feeding of ruminants during the period of forage shortage.

Low Efficiency

In the tropical area, productivity of ruminant has not optimized caused by the low quality of nutrition that leads to low-efficiency metabolism at the level of ruminal fermentation, post rumen digestibility, and intermediary metabolism. The study aimed to analyze effect of methionine hydroxy analog (MHA) on ruminal fermentation profiles of indigenous sheep specifically in the increase of ruminant productivity. In vitro utility test was conducted using rumen fluid of the indigenous sheep and sample of rational ration having a proportion of grass and concentrate 30%:70%, dry matter basis. The treatments implemented were three levels of MHA supplementation; T0: 0 g/day, T1: 3 g/day, and T2: 6 g/day. Variables measured were dry matter digestibility (DMD), organic matter digestibility (OMD), production of VFA, NH3, as well as total protein, and molar proportion of partial VFA of rumen fluid. Data were analyzed using analysis of variance (ANOVA) in a completely randomized design (CRD). The 0.2% MHA supplementation increased OMD with the highest production of total protein was from 28.57 mg/g (T0) to 40.49 mg/g (T2) (P<0.05). Meanwhile, the lowest ratio of acetate : propionate was from 2.74 (T0) to 2.33 (T2) (P<0.05). Supplementation of MHA up to 6 g/day concentrate increased the performance of fermentation and/or feed utility.
