he aim of this study was to evaluate fermentation and chemical characteristics and the in situ degradability of sorghum silages enriched with dried Leucaena. The experiment was conducted as completely randomized design with four treatments (0 - control silage, silage without leucaena; 10.0, 20.0, or 30.0% inclusion of Leucaena) and five replicates, totaling 20 experimental units. The inclusion levels of leucaena influenced (P 0.05), with all silages having values above 90%. Gas loss decreased (P < 0.05) as the level of leucine increased in sorghum silage. A linear increase was observed for dry matter (P ? 0.0001) and crude protein (P = 0.0008) contents in response to Leucaena inclusion. There was a linear (P < 0.05) linear effect on neutral detergent fiber, hemicellulose and acid detergent fiber. As leucaena inclusion levels increased, for each 1% inclusion a reduction of 0.179 was observed; 0.059 and 0.119% for the values of neutral detergent fiber, hemicellulose and acid detergent fiber respectively. The inclusion of leucaena influenced (P < 0.05) the increase of silage lignin levels, probably due to the higher lignin content of the legume. The soluble fraction (a) of the silages increased along with the Leucaena inclusion levels, with highest values observed at the inclusion of 20 and 30% of the legume, respectively. Potential degradation (A) increased linearly with the levels of Leucaena added to the silage; the highest value for this variable was observed at 30% inclusion. Effective degradability (ED) increased up to the inclusion level of 20% (46.77%). Degradation rate (c) decreased markedly with the use of 30% Leucaena. The use of the forage part of Leucaena dried for three hours leads to reduced gas production, increased dry matter and crude protein contents, and decreased fiber contents. The degradability of dry matter increases up to the inclusion level of 20%.

The effects of phosphate and nitrogen fertilization on aspects of forage composition and ruminal fermentation were separately evaluated pre- and post-grazing, in addition to the dry matter intake and weight gain of sheep grazing Panicum maximum cv. Massai under a rotational system on Quartzipsamment soil. The aim was to evaluate the effect of fertilization with different levels of phosphorous (50 and 200 kg P2O5/ha) and nitrogen (100 and 400 kg N/ha) compared to unfertilized control soil. The experiment was conducted at the School of Veterinary Medicine and Animal Science at Universidade Federal do Tocantins – UFT, in a randomized complete block design with four replicates in a factorial 2 × 2 design. The study area consisted of 32 paddocks (301 m²), each of which had previously been sown with Panicum maximum cv. Massai. The experimental area was managed under intermittent stocking with a variable stocking rate. Twenty-eight crossbreed sheep were used for grazing management. Evaluations were made before and after grazing, including forage evaluation and measurement of ruminal degradability and intake (using titanium dioxide as the external marker). Regarding the forage composition, a significant difference (P < 0.05) was observed between the control and fertilizer treatments for neutral detergent fiber (NDF), acid detergent fiber, crude protein, lignin and phosphorous content. Fertilization was found to alter the nutritional quality of Panicum maximum cv. Massai grass. Among the nutritional aspects evaluated, fertilization influenced NDF, grass digestibility and dry matter intake. The forage composition of Massai grass is improved by fertilization with nitrogen at 100 kg N/ha and phosphate up to 50 kg P2O5/ha, which represents a relevant management practice for increasing quantity and quality.

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.

Research was conducted to determine the quality and chemical composition of silages obtained by mixing in different ratios of narbonne vetch (Vicia narbonensis L.) and barley (Hordeum vulgare L.) grown in rabi season of 2017-2018 in Eastern Anatolia, Turkey. In the study we studied the pure sowings of barley and narbonne vetch and their mixtures (20, 30, 40, 50, 60, 70, 80% of narbonne vetch (N) + 80, 70, 60, 50, 40, 30, 20% of barley (B). The values of ADF (acid detergent fiber), NDF (neutral detergent fiber), DDM (digestible dry matter), DMI (dry matter intake), DM (dry matter), CP (crude protein) and RFV (relative feed value) of silages of analyzed were respectively 33.38, 33.73, 62.89, 3.57, 24.69, 15.50%, 174.64. We also founded that LA (lactic acid), AA (acetic acid), BA (butyric acid), PA (propionic acid) and Ca, P, Mg, K and pH of silages investigated were respectively 1.60, 0.57, 0.42, 0.06, 1.17, 0.53, 0.25, 3.51% and 3.80. Our results shows that silages with high narbonne vetch were higher quality values for CP, ADF, NDF, DM, RFV, DDM, DMI, Ca, Mg, LA which determined chemical composition and feeding quality of silages. As a result, it is suggested that mixture silages with narbonne vetch (80%) and the barley ratio (20%) have important advantages for some properties of silages.

The study was conducted to investigate the nutritive value and microbial status of different wholesale cuts of sheep carcass. The meat sample was obtained from 3 sheep. The ages of sheep were approximately of 1, 2 and 3 years. The wholesale cuts were shoulder, rack, loin and leg of each sheep carcass. The pH, juiciness, chemical composition, total bacteria, coliform bacteria, yeast and mould were studied to assess the quality of meat. The range of pH value were 5.077 - 5.927. The value of juiciness was decreased with the age. The value of dry matter, ash, crude protein, ether extract, calcium and phosphorus content of all samples were ranged from 23.32-30.40%, 0.88-1.027%, 20.50-24.88%, 8.10-12.13%, 0.012-0.038% and 0.048-0.185% respectively. Statistical analysis indicated that the value of pH, juiciness, dry matter, crude protein, ether extract, calcium, phosphorus and yeast (log value) was highly significant (P< 0.01) due to age and cut. Chemical composition, such as dry matter, ash, ether extract and calcium of all the samples increased gradually with the age, except crude protein, which decreased gradually with the age. The phosphorus content of the sample did not differ significantly due to age and cuts. The value of ash content was less significant (P<0.05) due to different cuts but highly significant (P<0.01) due to age. The range of total bacteria and coliform bacteria was 4.210-4.787 and 2.38-3.637/g of sample respectively. The range of yeast was 1.297-2.777/g of sample. Different meat cuts and ages did not show significant difference on total bacteria and coliform bacteria but in case of yeast, the value was highly significant (P<0.01) for the ages and cuts. Nutrient content of mutton varies due to different wholesale cuts as well as age. DOI: http://dx.doi.org/10.3329/bjas.v37i1.9865 BJAS 2008; 37(1): 32-38

Sugarcane may be a potential feed source for ruminants in tropical and subtropical areas. An important factor that can influence the nutritional quality of sugarcane for animal feeding is nitrogen fertilization management, however, studies on this subject are still scarce. In this context, the objective of this study was to evaluate the effect of nitrogen sources on the quality and productivity of sugarcane as a forage resource. The variety of sugarcane used was RB92579, with application of nitrogen (N) sources (urea, poultry litter, swine manure) and control (without N application). Stalk productivity and dry matter, crude protein, neutral detergent fiber, acid detergent fiber, lignin, Brix, NDF / Brix ratio, and in situ digestibility were analyzed during incubation periods of 6, 24, and 72 hours. At the end of the study, it was found that the N sources did not interfere with sugarcane stalk productivity (P> 0.05), with an average productivity of 102 t ha-1. The N treatments did not influence (P> 0.05) in the nutritional quality of sugarcane, when evaluating the contents of dry matter, crude protein, neutral detergent fiber, acid detergent fiber, lignin, Brix and NDF / Brix ratio. The dry matter degradation had an effect (P <0.05) for the different N sources and incubation times, where poultry litter and swine manure treatments showed higher values for degradation at 72 hours of incubation. The different N organic sources did not interfere in the chemical composition and productivity of the sugarcane culture, however it presented better results in the in situ degradability of the dry matter. This, it can be recommended that mineral nitrogen fertilizers can be replaced by organic fertilizers.

Background: Dry matter (DM) loss is high in sugarcane silage due to its high content of soluble carbohydrates which favors yeast growth and ethanol production, thus reducing the nutritional value of the preserved forage. Objective: To determine the effect of adding two types of urea at two concentration levels to sugarcane silage on the nutritional value and fermentative characteristics of the silage. Methods: A completely randomized 2×2+1 factorial design was used, based on two types of urea (conventional and protected), two urea concentration (0.5 and 1.0% of the natural matter), and a control (sugarcane silage with no additives). Six replicates were used. The mixture was placed in PVC silos and opened after 60 days. Results: There was no difference in DM content or effluent losses by the addition of urea. In regards to neutral detergent fiber, acid detergent fiber, and lignin, decreased levels were observed compared to the control, regardless of urea type. Urea type and concentration had an effect on ammoniacal nitrogen content, with higher values for conventional urea, but not affecting the pH. The addition of urea to sugarcane silage reduced gas losses and raised the levels of crude protein, ether extract, and effective degradability. Conclusion: Adding protected or conventional urea at 1% of natural matter at the time of sugarcane ensiling reduces gas losses and improves nutritional composition of the silage.

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.

Maize and soybean intercropping is a cereal-legume intercropping pattern that not only increases grain yield but also improves the nutritional value of silage. Experiments were conducted in the summer season to compare the yield and nutritional composition of the forage and silage quality of mono-cropped maize and intercropped maize-soybean harvested at two stages of maturity. The main treatments were one sole crop maize (SM) and four maize-soybean intercropping patterns (one-row maize to one-row soybean (1M1S), one-row maize to two-row soybean (1M2S), one-row maize to three-row soybean (1M3S), and two-row maize to one-row soybean (2M1S). The crops were harvested when the maize reached the milk (R3) and maturity (R6) stages. Results indicated a significant increase in the fresh biomass and dry-matter production of maize fodder alone compared with those of maize intercropped with soybean fodder. After 60 days of ensiling period, silage samples were analyzed for pH, organic acids, dry matter, crude protein (CP), ether extract, neutral detergent fiber (NDF), acid detergent fiber (ADF), and other mineral compositions. All intercropped silages showed higher CP values (1M1S, 12.1%; 1M2S, 12.2%; 1M3S, 12.4%; and 2M1S, 12.1%) than the SM silage (8.7%). Higher organic acids were produced in 1M3S than in the other silages. Correlation data showed that CP was highly correlated with lactic acid but negatively associated with crude fiber, nitrogen-free extract, and NDF. Thus, the intercropping of maize and soybean silage is recommended due its enhanced crop production, nutritional values in dairy animals, and prolific animal feedings and because it was scientifically evaluated as a feed stuff. This study indicated that 1M3S was the most preferable among intercropped silages in terms of nutrient composition.
