Abstract: The objective of this work was to evaluate the effects of combined phosphorus and nitrogen fertilization and of harvesting frequency on the chemical composition of 'Gigante' cactus pear (Opuntia ficus-indica) cladodes. The experiment was carried out in two municipalities, Quixadá and Tejuçuoca, in the state of Ceará, Brazil. Fertilization with nitrogen (urea) and phosphorus (single superphosphate) was done with nine doses, respectively: 10 and 70, 70 and 10, 70 and 70, 70 and 130, 100 and 100, 130 and 70, 130 and 130, 130 and 190, and 190 and 130 kg ha-1 per year, besides 100 kg ha-1 N and P2O5 per year as the control. The harvesting frequencies evaluated were annual and biannual. A randomized complete block design was adopted, in split plot, with four replicates. The effect of fertilization on the contents of total dry matter, crude protein, neutral detergent fiber, organic matter, and total carbohydrates in the cladodes varies with harvesting frequency and site. Regarding harvesting frequency, there were higher contents of organic matter, total carbohydrates, and neutral detergent fiber, but lower contents of crude protein for the biannual harvesting in both municipalities. Annual harvesting improves the nutritional quality of primary and secondary cladodes in the municipality of Quixadá and of secondary and tertiary cladodes in Tejuçuoca.

ABSTRACT The present study aimed to evaluate the agronomic productive and qualitative traits of forage of black oats grown in different stands of plants. The experimental design was a 2 x 2 factorial randomized complete block design consisting of four treatments, two plant stands (175 and 350 plants m2) associated with two successive cutting periods (vegetative and full vegetative) and four replications. The stand of plants did not influence the production of dry biomass; with 175 plants m2, we obtained a compensatory effect by the greater number of tillers m2-1 and/or tiller plant-1. The population stand influenced the chemical parameters, where 175 plants m2 resulted in forage with higher contents of hemicellulose and total digestible nutrients and a lower content of neutral detergent fiber. In the comparison between cuts, the first cut compared to the second presented higher values of crude protein (26.53%). It is recommended that the black oat be cultivated with a population stand of 175 plants m2 for generating an increase in the number of tillers m2-1 and tillers plant-1, in addition to improving the in situ dry matter digestibility of the whole plant, without causing reduction of production of dry biomass per unit area.

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.

Ten Napier grass genotypes (accessions) were assessed across 3 locations, Bako, Boneya Boshe and Gute, for forage dry matter (DM) yield, crude protein (CP) concentration, leaf:stem ratio, nutrient composition and digestibility characteristics during 2016 and 2017. The genotypes were evaluated in a randomized complete block design with 3 replications. Mean DM yield was higher for accession ILRI 16804 across all locations followed by ILRI 16801 and ILRI 16800. Leaf:stem ratio, CP concentration and CP and digestible organic matter (OM) yields also varied significantly among genotypes with the highest values obtained for accession ILRI 16804 across all locations, followed by ILRI 16800 and ILRI 16801. Yields of DM, CP and digestible OM and leaf:stem ratio were higher at Boneya Boshe and Gute than at Bako and higher during 2017 than during 2016. The consistently superior performance of ILRI 16804, ILRI 16801 and ILRI 16800 in both years across the 3 sites suggests that these genotypes should be studied further on farms and in differing environments before being recommended for general cultivation in this area. Examining performance with more frequent harvests and feeding studies with livestock would confirm the benefits to be obtained from planting these new accessions.

The objective of the present study was to evaluate the nutritional value of elephant-grass silages containing annato byproduct. Twenty intact rams were distributed in a complete randomized block design with five diets (0; 4; 8; 12 and 16% annato byproduct in the silage) and four replications and used to estimate the intake, apparent nutrient digestibility, content of total digestible nutrients and nitrogen balance. The addition of annato byproduct raised the intakes of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), total carbohydrates (TC), non-fibrous carbohydrates (NFC) and total digestible nutrients (TDN), in body weight (%BW) and in metabolic weight (g kg-1BW0.75). The digestibilities of DM (55.95%), OM (58.19%), CP (45.34%), NDF (52.79%), ADF (45.79%), EE (34.96%) and NFC (99.86%) were not influenced by the addition of annato byproduct. The inclusion of annato byproduct in elephant-grass silage increased digestibility of total carbohydrates, the TDN content and the nitrogen balance. The aditions of annato byproduct at levels up to 16% of the elephant grass silage natural matter improves nutrient intake and nitrogen balance.

ABSTRACT The goal of this work was to assess the biomass production and bromatological quality of ryegrass genotypes in ten municipalities of the Western and North Plateau regions of the State of Santa Catarina, Brazil. The cultivars La Estanzuela 284 (diploid), Bar HQ, Barjumbo, INIA Escorpio, Potro, and Winter Star (tetraploids) were compared, distributed in a randomized block design, in which the municipalities constituted the blocks, with three replications. The cuts were performed when the plants reached 30cm, leaving a residue of 10cm. In three cuts, the cultivars Barjumbo and Bar HQ were the most productive, exceeding 4.6 t ha-1 of dry matter. In the places in which five cuts were performed, the production of these cultivars exceeded 7.3 t ha-1, placing them again ahead of the others. The average crude protein content in three cuts was greater than 25% in all cultivars. There was no difference between the genotypes in the content of neutral detergent fiber and total digestible nutrients. There was a significant correlation between quantitative and qualitative productive variables. The assessed cultivars represented good options for composing short-term or long-term winter-feeding systems, adjusted to the integration with annual crops or warm-season pastures.

It was used 27 goat kids (18 ¾ Boer + ¼ Saanen and nine Saanen; 18.0 ± 1.60 kg) distributed in a completely randomized design with factorial arrangement to evaluate productive performance and the total digestibility of dry matter and nutrients in the rations. Diets were composed of soybean meal, soybean meal + dry yeast or dry yeast as protein source, oat hay, ground corn and vitamin-mineral mixture with mean composition of 2.50 Mcal of ME/kg DM and 17.0% of crude protein on average. Digestibility was determined using indigestible neutral detergent fiber as marker. Intakes of dry matter, organic matter, crude protein and total carbohydrates were not altered by rations. However, inclusion of dry yeast in the rations reduced ingestions of ether extract, neutral detergent fiber and acid detergent fiber. Within breed groups, the ¾ Boer + ¼ Saanen goat kids showed the highest intakes of dry matter and nutrients, as well as the best means of daily gain, feed conversion and days in feedlot. Digestibilities of dry matter, organic matter, crude protein and total carbohydrates were higer - and the digesbility of ether extract was lower - for animals fed rations with dry yeast. There were no differences in digestibility of neutral detergent fiber. Rations with dry yeast showed the highest values of total digestible nutrients. Dry yeast can be used as alternative protein source in rations for goat kids because it does not change animal performance and it does have higher nutritional value than soybean meal. ¾ Boer + ¼ Saanen kids show, in feedlots, better performance in growth and finishing phases when compared to Saanen kids.

An experiment was carried out to assess the nutritional value along with quality of curds in late season cauliflower varieties at Rampur, Chitwan during November 2017 to March, 2018. The eleven late season cauliflower varieties were Freedom, Titan, Ravella, Amazing, Artica, Bishop, Casper, Indam 9803, NS 106, Snow Mystique and Snowball 16 which were introduced from USA, Europe, India and Nepal. The experiment was prepared in a Randomized Complete Block Design (RCBD) with four replications. The main objective of this study was to check the nutritional content, taste, compactness, appearance and freshness of the curds in eleven late season cauliflower varieties at Rampur, Chitwan. Nutritional value along with taste quality, compactness, appearance and freshness of the curds were measured after harvest. Maximum moisture and carbohydrate content was found in Freedom while higher crude fat was obtained in Titan and Bishop. Similarly, higher crude protein and crude fiber was found in NS 106. Significantly better taste score (8.8) was found in Snowball 16 than other varieties. Better compactness score of curd was found in Artica and Titan than other varieties. Significantly better appearance score (8.0) was found in Artica but poor appearance score was found in Casper than other varieties. At different intervals after harvesting of curds, significantly fresher curds were found in Artica than other varieties. In conclusion, NS 106 performed higher content of crude protein and crude fiber while Snowball 16 executed better tasty curds than other varieties. Artica also showed better performance on freshness of curds than other varieties. Int. J. Appl. Sci. Biotechnol. Vol 8(4): 427-431

ABSTRACT The objective of the present work was to evaluate the chemical composition, fermentation profile, and degradation parameters of the neutral detergent fiber of three silages made with the waste from production of heart of peach of palm, which consisted of leaf, leaf sheath, and their compound (55% leaf and 45% leaf sheath). The waste was packed in experimental silos and open after sixty days of fermentation; silage samples were collected for determination of chemical composition and degradation parameters of neutral detergent fiber at 0, 3, 6, 9, 12, 24, 36, 48, 72, and 96 h of incubation in vitro. A difference was detected in the dry matter, crude protein, neutral detergent fiber, acid detergent fiber, and lignin contents between the three types of silage. The leaf silage showed a higher fractional degradation rate and a higher potentially digestible fraction of neutral detergent fiber over the 96 h of incubation. As for the fermentative parameters, silage made with the leaf showed a higher pH (3,79) and lactic acid (1,18%), acetic acid (0,39%) and propionic acid (0,24%). The butyric acid was higher for compound silage (0,012%) and ammoniacal nitrogen was higher for sheath silage (0,94%). The leaf silage displayed better chemical characteristics, fermentation parameters and in vitro degradability properties, proving to be the silage with best nutritional value for feeding ruminants.

The study aimed to evaluat the chemical composition of forage cactus cladodes of the genus Opuntia spp. at different stages of phenological development. The experiment was conducted in a completely randomized design, with a 4×3 factorial scheme, with four species of cactus (Opuntia stricta Haw, Opuntia undulata Griffiths, Opuntia atropes Rose and Opuntia larreri FAC Weber) and three stages of cladode development (young, intermediate, and mature). The chemical composition of Opuntia cladodes varied according to species and phenological stage. Dry matter (DM), neutral detergent fiber (NDF) and acid detergent fiber (ADF) concentrations increased, and crude protein (CP) decreased with cladode maturation. The species O. atropes had the lowest levels of organic matter (OM), CP, total carbohydrates, and non-fibrous carbohydrates, as well as the highest values of mineral matter, NDF and ADF. Calcium and phosphorus contents increased with cladodium maturation. The concentrations of boron, copper and manganese were higher in the young and intermediate stages. The cladodes of O. stricta, O. undulata and O. larreri showed better nutritional quality for feeding domestic ruminants. Young and intermediate cladodes are more proteinaceous and less fibrous. These results can be useful in selecting the forage cactus species and in optimizing the use of cladodes for feeding different categories of ruminants in semiarid regions.

The objective of this work was to evaluate the chemical composition and rumen disappearance rate of dry matter of corn silages with inoculants combining L. buchneri strain LN40177 in different strata of the silo. The experimental design was a 3x2 randomized complete block design, with three treatments: Control: corn silage without inoculant; 11CFT: corn silage with inoculant which combines L. buchneri strain LN40177 (1.1 x 1011 CFU g-1) with L. casei (1.1 x 1011 CFU g-1); and 11C33: corn silage with inoculant which combines L. buchneri strain LN40177 (1.1 x 1011 CFU g-1) with L. plantarum (1.1 x 1011 CFU g-1) and Enterococcus faecium (1 x 1010 CFU g-1), associated with two strata of the silo (lower and upper). The silage inoculated with 11C33 presented higher contents of crude protein and NDF and lower hemicellulose content in relation to the control treatment and 11CFT. The use of both inoculants resulted in silages with higher concentrations of soluble nutrients. Lower stratum silage had a higher rumen disappearance rate of dry matter compared to the upper stratum. In general, the combinations of L. buchneri promoted nutritional improvements in corn silage, but in presence of L. casei, there were more outstanding improvements.
