Twenty experimental silages were made from seven pasture species at different stages of maturity. In vivo dry matter, organic matter, and energy ad libitum intakes and digestibilities of the silages were determined with standardized pairs of Merino wethers. The following chemical characteristics of the silages were measured: nitrogen, ammonia nitrogen, total titratable acids, acetic, propionic, butyric, and lactic acids, total volatiles lost during oven drying, lactic acid as a percentage of the total organic acids, pH, acid pepsin dry matter disappearance, dry matter content, and in vitro digestibility and rate of digestion. When all 20 silages were considered, energy intakes on a body weight basis were significantly related to silage pH (r = 0.55) and rate of in vitro digestion (r = 0.58). When the five legume silages were removed from the analysis and only the 15 grass-dominant silages were considered, dry matter intakes were significantly related to acetic (r = –0.57) and propionic acid (r = –0.55) concentrations. Multiple regression analyses did not significantly increase the accuracy of predicting intake. The results suggested that silage intake was negatively related to the degree of fermentation that occurred during the ensiling process.

In this study, corn silage with different ratios of by adding olive pomace olive industry by-product under laboratory conditions was aimed to determine the effects on nutrient contents, fermentation characteristics and in vitro digestibility. Olive pomace used in the research, was added in 0% (control), 20 and 40 levels in corn silage and ensiling period continued during 56 days. At the end of the ensiling period, differences seen in terms of dry matter content, organic matter, crude fat, acit detergent fiber, acid detergent lignin, in each level consisting of corn silage is added to olive pomace were found significant but the crude protein content of the olive pomace-added silages decreased. The highest crude fiber value was determined in the silages added with 40% olive pomace. Crude ash, lactic acid, acetic acid, pH and CO2 differences seen in terms of rates were not found significant. Propoionic acid wasn’t found in the groups to which olive pomace was added, while butyric acid and ammonia nitrogen weren’t observed in all silage groups in the study. At the same time, in vitro organic matter, dry matter and neutral detergent fiber digestibility of silages increased in each level consisting of corn silage is added to olive pomace. As a result, it was considered result that olive pomace the oil industry by product can be a silo feed quality. In particular, the corns by adding 40% of the olive pomace made silage were obtained satisfactory results in terms of both physical and chemical properties.

Cutting Height

The goal of this study was to assess the dehydration curve and nutritional value of Tifton 85 bermudagrass at two cutting heights from ground level (4 and 8 cm) during 120 days of storage in a closed shed. The dehydration curve was determined using samples from the entire plant at eight different times. The experimental design consisted of randomized blocks with plots subdivided per times and five replicates. The second step consisted of assessing the nutritional value of the stored Tifton 85 bermudagrass in randomized blocks with plots subdivided per times and two treatments per plot: cutting height of four and eight centimeters from the ground, and five different times for the subplots, with five replicates. Dehydration of Tifton 85 bermudagrass at the two heights occurred in 48 hours, considered an ideal time for hay drying. The dry matter content responded quadratically to the time of storage of the two heights, only differing during baling and after 120 days of storage. Crude protein content had a quadratic behavior in the two cutting heights, with the smallest value after 30 days of storage (107.0 g kg-1) and the largest after 90 days (147.8 g kg-1) in the cutting height of eight centimeters. The ether extract exhibited a quadratic behavior in the two cutting heights, only differing after 90 days of storage. The neutral detergent fiber content had linear positive response according to the time of storage, with no difference between the cutting heights. For the neutral detergent fiber content in the two cutting heights, the quadratic regression model was the best fit to the data, differing between the heights after 30 and 60 days of storage. In vitro dry matter digestibility and in vitro cell wall digestibility values of the stored hay were lower than the values obtained at the time of cutting. Cutting performed at four centimeters from the ground was the most suitable for hay production due to higher dry matter production and nutritional value without difference between bailing treatments. Hay storage caused undesirable changes in the nutritional value, especially in fiber content and in vitro digestibility.

This study evaluated silages made with varying proportions of viticulture by-products (VC) and starch extraction from cassava (CSE). It attempted to determine the effects of these proportions on the microbial population, fermentative losses, and chemical composition. The treatments were specified as the proportions of VC in the silage (0 g/kg, 250 g/kg, 500 g/kg, 750 g/kg, and 1000 g/kg). Silages were  evaluated before (0) and after 1, 3, 7, 15, 30, and 60 days of ensiling. The experimental design was completely randomized with five  treatments, six storage times and four replications. The increased level of VC in the silage enhanced its dry matter content, ammonia  nitrogen (NH3-N), and buffering capacity, and reduced organic matter content. Fifteen days after ensiling, additional VC increased the concentration of soluble carbohydrates. The increased level of VC decreased the count of Clostridium spp. and lactic acid bacteria (LAB). The incidence of yeasts and enterobacteria was low in all treatments at all time points. Over time, losses as effluent and gases increased. Use of increasing proportions from VC in silage made with CSE increased the contents of dry matter and soluble carbohydrates and  reduced the fermentative losses of the silage. The increased amount of VC also favoured pH reduction and reduced the proliferation of undesirable yeasts, while increasing the population of LAB.

Dry Matter Digestibility

The objective was to evaluate the productivity, chemical composition, ruminal degradability of dry matter and digestibility of BRS capiaçu grass (Pennisetum purpureum Schum.) managed at five regrowth ages. A completely randomized design with ten replications was used in the BRS capiaçu elephant grass subjected to five cutting intervals (30, 60, 90, 120 and 150 days) in the summer, making a total of 50 plots with a useful area of 4 x 2 m. There were daily increases in the dry matter production in the order of 382 kg ha-1, with 49,859 kg ha-1 being produced at 150 regrowth days. The dry matter content and organic matter linearly increased (P < 0.01) at different regrowth ages. The crude protein content, in vitro dry matter digestibility and in vitro digestibility of neutral detergent fiber linearly reduced (P < 0.01) 0.037%, 0.196% and 0.256% per day, respectively. Potential degradability of dry matter decreased from 68.9% at 30 days to 44.7% at 150 regrowth days (0.194 percentage units per day). The rate of degradation of fraction B 'c' was not modified (P = 0.94), averaging 1.46% hour-1. In the cultivation of BRS capiaçu elephant grass in the summer season, in the northern region of Minas Gerais, the age for harvesting between 90 and 120 days of regrowth is recommended.

The Relationship

A 2-yr study was conducted at Elora and Brucefield, Ont. to examine the relationship between grain yield following grain physiological maturity and whole-plant dry matter (DM) yield and quality determined at the stage desirable for ensiling. Quality parameters analyzed include in vitro dry matter digestibility (IVD) of the stover, IVD of the whole plant, stover lignin content and stover protein content. There was a significant linear relationship between the performance of hybrids for grain yield production and their yield for silage production. However, the relationship was not complete enough to permit reliable selection of hybrids for silage production based on grain yield performance (coefficients of determination were 0.23 and 0.25 for Elora and Brucefield, respectively). Grain dry matter content, however, provided a satisfactory estimate of whole-plant maturity for silage production. Coefficients of determination between grain DM content and whole-plant DM content were 0.71 and 0.53 for Elora and Brucefield, respectively. There was considerable variation among hybrids for lignin content and IVD of stover. Differences were much less for whole-plant IVD. The findings of this study support the need for separate evaluation trials for corn grown for whole-plant silage production as opposed to grain production.Key words: Zea mays, corn silage, grain yield, hybrid performance

SUMMARYA total of 156 pigs of the Large White breed were used in a series of four experiments to test the suitability of barley which had been stored with a high moisture content as an ingredient in the diets of growing pigs. Barleys with mean moisture contents of 26·3%, 28·1% and 21·2% and a range from 19·6% to 30·5%, from three successive harvests were used.In all the trials there was evidence that the use of moist barley in diets for growing pigs had an adverse effect on live-weight gain and feed conversion ratio, the effect being independent of whether feed intakes were equated on the basis of the dry-matter content of the diets. In one of the experiments performance was depressed to the extent of causing changes in carcass characteristics. The performance of pigs given rolled barley was similar to that of others given ground barley.

Study Species

Four species of Restionaceae and Cyperaceae from the Mediterranean-type climate region of Western Australia were studied to determine factor(s) limiting their reproductive performance. Ecdeiocolea monostachya (Ecdeiocoleaceae), Lepidobolus chaetocephalus (Restionaceae), Restio aff. sphacelatus (Restionaceae) and Mesomelaena pseudostygia (Cyperaceae) differed in the pattern of dry matter partitioning and phenological patterns. All species were moderately efficient at remobilising dry matter from senescing vegetative organs, maintaining constant tissue water to dry matter content in mature organs over the study period regardless of soil moisture availability. In situ nutrient and water supplements of study species did not elicit improved seed production or significant increases in dry matter accumulation (except for current and old culms of E. monostachya and spikelets of L. chaetocephalus). For all study species except L. chaetocephalus, seed production was low, while herbivore activity, insect predation andlor infection by a smut (Tolyposporium lepidiboli) reduced seed production potential in L. chaetocephalus and E. monostachya. Attempts at seed germination for all study species were not successful. Extracted embryos from mature seed of all species cultured in vitro grew rapidly, providing a reliable method for propagation of study species.
