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.

ABSTRACT The objective of this study was to evaluate the nutritive value of sugarcane silage with or without inoculation with P. acidipropionici or L. buchneri, over three fermentation periods. The experimental design was completely randomized in a 3 x 3 inoculant by fermentation period factorial arrangement (without inoculant, inoculant 1, inoculant 2; x three fermentation periods, 10, 60, 90 days). Values of pH, dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM) and lignin were determined and in situ DM degradability profiles were modelled for parameters a, b and c, potential degradation (A) and effective degradability (ED). The 90 day fermentation yielded a lower pH for both inoculants. There was an interaction between inoculant and fermentation period (P < 0.05) for DM content, with a reduction in silage DM without the additive at 90 days. The CP, HEM, ADF and lignin contents of sugarcane were not influenced by the treatments. The addition of P. acidipropionici provided the lowest NDF content at 10 days and presented a higher fraction a, potential degradation and ED. At 60 days, there was no variation in soluble fraction, the control silage showed a higher fraction b, higher potential degradation and ED. At 90 days of fermentation, L. buchneri silages presented a higher fraction a, degradation rate and DE and a higher b value was obtained in the silage without inoculant. Inoculants are effective in maintaining the silage DM content and nutritional value during prolonged fermentation periods.

To evaluate the bromatological composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Xaraés palisade grass (Urochloa brizantha ‘Xaraes’ syn Brachiaria brizantha) under grazing in integrated crop, livestock (ICL), and forest (ICLF) systems, we conducted an in situ degradability trial in randomized blocks with three non-lactating 3/4 Gyr × 1/4 Holstein cows, provided with ruminal cannula. The management of Xaraés palisade grass was similar in both systems, differing only regarding shading in the ICLF system provided by eucalyptus trees (average 65% crown cover). Grass samples were incubated for 0, 3, 6, 9, 12, 24, 36, 48, 72, and 96 hours. Considering the passage rate 2% h-1, the Xaraés palisade grass of ICL system had greater NDF effective degradability in relation to ICLF (46.38% vs 44.98%). However, the palisade grass CP potential degradability was greater in the ICLF than in the ICL system (68.92% vs. 65.40%). The presence of trees in the pasture has effect on nutritional traits of the Xaraés palisade grass, increasing its protein content and degradability and reducing its fiber degradability.

The objective of this study was to evaluate the in situ degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and hemicellulose of elephant grass (Pennisetumpurpureum, Schum.) with increasing levels (0; 35.0; 70.0, 105.0, and 140.0 g kg-1) of dried pineapple (Ananascomosus, L.) by-product (DPBP). The experimental silos consisted of plastic drums with 210 L capacity. After weighing and homogenizing the elephant grass with the DABP, the material was inserted in the silos (126 kg silage, at a density of 600 kg m-3) and compressed. After 45 days of ensilage, silos were opened and samples of the silages were collected for the trial. The study of degradability in situ was conducted using a rumen-fistulated male cattle. The animal was fed with corn silage supplemented with 1 kg concentrate daily. Five levels of addition of the by-product were tested, with three replicates and five times of incubation with an animal. The experimental design was completely randomized with split plots, in which the proportions of DPBP were the treatments (plots), the different silos were the replicates, and the incubation times were the subplots. The levels of inclusion of DPBP provided an increase (P &lt; 0.05) in disappearance of DM and CP and in the effective degradability of DM, NDF, ADF, and hemicellulose. The dried pineapple by-product is a potential alternative to be used as additive in the ensilage of elephant grass, as it provides an increase in the rumen degradability parameters.

This study was conducted to determine the effect of row spacing (40, 60 and 80 cm) on forage dry matter (DM) yield and quality of four hybrids grown in the years 2001 and 2002. The highest DM yield was obtained from the Arifiye (24.1 and 22.4 t/ha) while the lowest DM yield was obtained from Pioneer 3163 (19.9 and 19.8 t/ha) in the years 2001 and 2002, respectively. As row spacing increased, DM yield as an average of two years decreased from 27.2 to 16.6 t/ha. No differences were found among row spacing for DM content, harvest index (HI) and ear content. As row spacing increased, whole-plant acid detergent fiber (ADF) and neutral detergent fiber (NDF) content increased from 214 to 227 g/kg and from 420 to 451 g/kg during the year 2001, respectively. However, ADF content decreased from 281 to 267 g/kg and NDF contents decreased from 530 to 515 g/kg with increasing row spacing during the year 2002. In this study, hybrids showed distinct differences for crude protein, ADF and NDF contents in both years. Forage quality parameter including ADF and NDF of Pioneer 3163, TTM 8119 and Karadeniz Yildizi were higher than Arifiye hybrid.

Ruminal Degradability

A study was conducted to determine the effects of forage soybean cultivar on chemical composition, ensiling characteristics, and ruminal degradability of silage. Two cultivars of forage soybean (Kodiak and Mammouth) were field-grown, harvested at the R6 stage, and ensiled in mini-silos (n = 3) for 0, 2, 4, 8, 16 and 45 d. Two ruminally fistulated cows were used to determine in situ ruminal nutrient degradabilities of the 45-d silages. Both cultivars went through slow fermentation as indicated by a gradual decline in pH up to day 45 post-ensiling. Lactic acid concentration increased throughout ensiling and was higher for Mammouth than Kodiak except at day 45 post-ensiling. Analysis of the 45-d silages showed that Mammouth contained higher neutral detergent fiber (NDF, 490 vs. 444 g kg-1), acid detergent fiber (371 vs. 353 g kg-1) and acid detergent lignin (81 vs. 64 g kg-1) than Kodiak. However, crude protein (CP) concentration was higher for Kodiak than Mammouth. Mammouth silage had lower buffer soluble protein and higher neutral and acid detergent insoluble protein concentrations than Kodiak silage. Results of the in situ study indicated that Kodiak silage had greater ruminal dry matter (606 vs. 549 g kg-1), CP (828 vs. 752 g kg -1) and NDF (272 vs. 227 g kg-1) degradabilities than Mammouth. It was concluded that chemical composition and ruminal nutrient degradabilities of forage soybean silage were significantly influenced by cultivar. Key words: Soybean [Glycine max (L.)

The goal of this work was to evaluate the nutritional quality in 3 cultivars of alfalfa, belonging to different winter dormancy (GRI), subjected to two cutting frequencies during one year of cultivation, based on the abundant information existing in studies carried out in productivity, coverage and persistence, not so in the determination of quality of forage subjected to different frequencies of cuts and contrasting GRI. Three cultivars (GR6-Verzy), (GR9-Mecha) and (GR10-Ruano) were tested. The experimental design was a complete split plot with four repetitions. Two treatments defined by the cutting intervals were established: T1: 25 days and T2: 35 days. These were specified for spring, summer and fall seasons. For winter the interval was 45 and 55 days in T1 and T2, respectively.  The evaluated variables were: percentage of dry matter (% DM), percentage of crude protein (% PB), percentage of neutral detergent fiber (% FDN) and percentage of acid detergent fiber (% FDA). Significant differences were found for all the nutritional variables studied, for both treatment with p <0.05 with InfoStat program. Interaction between cultivars and treatment was observed for % PB. The 35 days cutoff frequency of yielded the lowest percentages of PB and the highest percentages of FDN and FDA. Hence the forage resulting from this frequency is of a lower quality, leading to decreased digestibility and lower performance of pasture for livestock.

This study evaluated the inclusion of increasing contents (0; 35; 70; 105 and 140 g kg-1) of dried acerola fruit (Malpighia glabra, Linn.) by-product (DABP) in the ensilage of elephant grass (Pennisetum purpureum, Schum.) considering the in situ degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and hemicellulose. Plastic drums with 210 L capacity were used as experimental silos. After 45 days of ensiling, silos were opened and silage samples were collected for the degradability trial and laboratory analysis. For the in situ degradability trial, was used one rumen-fistulated adult male cattle. The five by-product inclusion contents were tested in three replicates, with five incubation times, in a randomized complete split-plot design in which the contents of DABP were the treatments (plots), the different silos were the replicates and the incubation times were the sub-plots. Longer incubation times significantly increased (P < 0.05) the disappearance rates of DM, CP, NDF, ADF and hemicellulose. The effective degradability of the DM, NDF and hemicellulose was higher in the silages with 35 g kg-1 of DABP in the rumen passage rates of 0.02; 0.05 and 0.08 h-1. Dried acerola fruit by-product can be added to elephant grass ensiling up to 35 g kg-1 without reducing the effective degradability of nutrients.

Abstract This study was aimed to estimate the effect of cultivation stage and supplementation level of sprouted barley (SB) on nutrient content and fermentation quality of fermented total mixed ration (TMR). The SB were collected at day 6 (SB6) and day 8 (SB8) of cultivation stages and substituted at 5% (TMR5) and 10% (TMR10) of TMR on dry matter (DM) basis. These TMR were ensiled into 10 L mini silo (3 kg) for 14 days in triplicate. After silo open, sample (1 kg) was collected for laboratory analysis. Before ensiling, crude protein (CP) was lower (P = 0.012) in SB6 than in SB8. Additionally, DM in TMR10 was slightly lower (P = 0.015) than in TMR5 while CP and acid detergent fiber were higher (P &lt; 0.05). After fermentation, crude ash (P = 0.002), in vitro DM digestibility (IVDMD) (P = 0.001; 73.5 vs. 72.0%) and in vitro neutral detergent fiber (IVNDFD) (P = 0.001; 50.6 vs. 47.7%) were higher in SB6 than in SB8. Additionally, DM (P = 0.002; 64.0 vs. 64.5) in TMR10 was lower than in TMR5, while CP (P = 0.005; 19.7 vs. 18.9%), IVDMD (P = 0.001; 74.5 vs. 71.0%), and IVNDFD (P = 0.001; 52.0 vs. 46.3%) were higher. Fermentation indices and microbial counts were not affected by cultivation stage of SB, except on propionate that higher (P = 0.014) in SB8 than SB6. Silage pH (P = 0.001) was lower in TMR10 than in TMR5, which followed by higher lactate (P = 0.003; 3.27 vs. 2.85%), acetate (P = 0.004; 0.52 vs. 0.42%), propionate (P &lt; 0.001), and LAB count (P = 0.020; 7.49 vs. 7.19%). The interaction effects between cultivation stage and supplementation level only found on propionate production (P = 0.001). Yeast and mold were not affected by cultivation stage and supplementation level of SB. This study concluded SB6 was recommended to improve fermentation quality of fermented diet, and its application on TMR10 could increase not only rumen digestibility but also fermentation indices.
