The use of silage has been an efficient alternative to feed supply during the shortage of roughage in dry periods, providing quality feed that is widely used in ruminant feeding. Thus, the objective of this study was to evaluate the fermentative characteristics and nutritive value of corn silage with Tamani guinea grass (Panicum maximum BRS cv. Tamani) through chemical composition, in vitro dry matter digestibility and protein fractionation. The experiment was conducted in a completely randomized design with four replications. The treatments consisted of five silages: corn; corn with 10% Tamani guinea grass; corn with 20% Tamani guinea grass; corn with 30% Tamani guinea grass; and corn with 40% Tamani guinea grass, totalling 20 experimental silos. The addition of tamani grass to silages was determined based on fresh matter. For ensiling, corn was harvested with 320 g kg-1 DM (dry matter) and Tamani guinea grass in a 30-day development cycle with 286 g kg-1 DM. After 50 days of silage, the silos were opened to analyse the fermentative characteristics, chemical composition and protein fractionation of the silage. The results showed that the addition of Tamani guinea grass in corn silage increased the pH and buffering capacity and reduced the dry matter and lactic acid concentration but did not compromise the fermentative characteristics of silages. The addition of 40% Tamani guinea grass in corn silage provided increased levels of crude protein, in vitro dry matter digestibility, protein A, B1 and C, and decreased the fractions B3 and C, which makes Tamani guinea grass an alternative to improve the quality of exclusive corn silage, resulting in better quality silage.

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.

The agronomic performance and nutritive value of Mucuna legume (Stilozobium deeringianum (Bort) Merr.) in five stages were evaluated under climatic conditions of Peruvian central coast to estimate optimum stage of use. Five cutting ages were: 21, 42, 63, 84 and 105 days. Crop growing, forage yield, chemical composition, vitro dry matter digestibility and net energy for lactation of Mucuna were evaluated. The optimum cutting age was 84 days with 25633.3 kg. Ha-1 of fresh matter and 6422.6 kg-1 ha-1 of dry matter. In this age crude protein, neutral detergent fiber and acid detergent fiber and in vitro dry matter digestibility contents were 14.94%, 44.80%, 33.15% and 66.12 %. Net energy for lactation was 1.43 Mcal.kg-1. These results show that Mucuna was well adapted to Peruvian Central Coast with high forage yield and nutritive value.

<p>The aim of this study was to evaluate performance and in vitro digestibility of Guinea grass grown on saline soil. Yield, quality, and in vitro digestibility of Guinea grass cultivated on coastal area with crop populations of 10,000,<br />20,000, and 30,000 plants per hectare. Experiment was conducted following randomized complete block design (RCBD). Higher crop population increased fresh and DM biomass production, crude protein (CP) yield, dry matter<br />(DM) content, neutral detergent fiber (NDF), lignin, and hemicellulose content, but decreased CP content, and in vitro organic matter digestibility (OMD). The increased population had no effect on acid detergent fiber (ADF) and in vitro<br />dry matter digestibility (DMD). It could be concluded that guinea grass was recommended to be planted in saline coastal area by addition of fertilizer 20 tons/ha manure, 3 tons/ha gypsum, and 50 kg N (239 kg ZA/ha) as source of<br />nitrogen.</p><p><br />(Keywords: Forage, Salinity, Saline soil, Manure, Gypsum, Nitrogen source)<br /><br /></p>

Ruminal Digestion

Chemical composition and ruminal digestion parameters were mea- sured in the silage of the whole corn plant (Zea mays L.) mixed with mulberry foliage (Morus alba L.) in ratio of 100:0, 80:20, 60:40, 40:60, 20:80 and 00:100% of fresh forage weight, respectively. The 40:60 ratio of corn: mulberry increased crude protein content (CP = 14.28%) and decreased hemicellulose (12.15%), neutral (NDF = 28.00%) and acidic (ADF = 15.85%) detergent fiber, compared to 100: 0% ratio, respectively, which led to a 21.3% increase in in vitro dry matter digestibility (IVDMD). Also ammoniacal nitrogen 7.40% (NH3-N/total N) was higher in the ratio 40:60%, with pH of 4.19 which is normal for silages, which translates the buffer activity correct of ammonia and its importance for silage fermentation stability. The correlation (r = 0.61, p < 0.001) indicated that at higher CP content, higher is IVDMD and hemicellulose (r = -0.99), ADF (r = -0.98) and NDF (r = -0.98) indicated that these fibrous compounds decreased IVDMD (p < 0.001). The regression showed that the increase in content CP (0.555%, p < 0.01) and IVDMD (0.3391%, p < 0.001) with the decrease of NDF (-0.3526%), ADF (-0.1623%) and hemicellulose (-0.1903%) (p < 0.001) in mixed mini silos, was attributed to mulberry foliage addition. It is concluded that the contribution of dry matter and nitrogen of mulberry, decreased the fiber content and increased digestibility parameters of silage when it is elaborated in ratio of 40:60 corn and mulberry, respectively.

The research submitted samples from stems and leaf blades from tree genotypes of Pennisetum purpureum called 93-32-02, 92-70-02, and 91-06-02 (EMBRAPA - Dairy cattle) and elephant grass cv. Napier (reference cultivar) to the chemical, anatomical evaluations, and in vitro dry matter digestibility (IVDMD) measurement. The anatomical characteristics of the stems and leaf blades, the chemical composition, and the IVDMD of these genotypes at 70 days of re-growth were correlated. Concerning IVDMD, the data highlighted differences, and the cultivar Napier presented the smallest value. Digital images obtained by light microscopy from cross-section reveal that all the stem and leaf blade have similar structural organization. Quantitative differences were verified mainly in the stem. The leaves displayed differences only in the mesophyll thickness. The genotypes showed higher potential in the rainy season since they had the largest IVDMD when compared to the cultivar Napier.

Guinea Grass

The experiment was conducted to determine the nutritive value of ensiled guinea grass with different additives using in-vitro gas production method. The silage were in 5 treatments T1: 90% of guinea grass + 10% yellow maize residue, T2: 90% of guinea grass + 10% white maize residue, T3: 90% of guinea grass + 10% guinea corn residue, T4: 90% of guinea grass + 10% soy bean residue, T5: 100% of guinea grass.. The silage quality, physical properties, chemical composition, the in vitro gas production after 24hours of incubation were investigated. Methane (CH4) gas produced was measured. Metabolizable energy (ME), Organic matter digestibility (OMD) and the short chain fatty acid (SCFA) were estimated from the in vitro gas production parameters. The colour of the silage varied among the silage treatments and were closer to the colours of the fresh forage. All the silage had pleasant smell and the temperature had no significant difference among the silage treatments. The pH ranged from 4.23 � 5.60 which has significant difference among the silage treatments. The chemical composition of the silage were as follows: Dry matter (DM) 23.73 to 29.50%, Crude protein (CP), 6.93 to 11.05%; Crude fibre (CF), 27.84 to 31.20%; and ash, 15.01 to 17.50%. Hemicellulose ranges from 23.29 to 26.05%, Cellulose ranges from 21.07 to 30.50%. The mineral composition value of the ensiled ranges are as follow: CA, 0.19 to 0.23%; P, 0.17 to 0.19%; NA, 0.08 to 0.11%; k, 0.34 to 0.45%; MG, 0,10 to 0.13%. Potential gas production varied from 13.00 ml/200mg DM to 18.67 ml/200mg DM. The high (P<0.05) potential gas value of 18.67 ml/200mg DM was obtained for silage T4. The highest value of ME (5.41MJ/kg DM); OMD (46.10%) and SCFA (0.51-mol) were obtained in silage T3 which contain 90% guinea grass with 10%guineacorn residue. Result indicates that silage from 90% guinea grass with 10% white maize residue have the best nutritive value.

The influence of the improved drainage broadbed and furrow (BBF), as opposed to the traditional flat seedbed over the growing season on the dry matter yield and nutritive value of Avena sativa, Vigna unguiculata, Lablab purpureus, Vida dasycarpa, Trifolium steudneri and Sesbania sesban were studied on Vertisol. Up to 7 t/ha dry matter yield was recorded for Avena sativa and Lablab purpureus when planted on Vertisols with improved drainage. Dry matter yield of forage crops also increased with advance in stage of maturity or subsequent harvests. On both improved and traditional flat seedbed methods, the chemical analysis of forage crops showed similar declines in crude protein content and in vitro dry matter digestibility (IVDMD) levels as the maturity of forage crops progressed.
