The objective was to evaluate the qualitative and nutritional aspects of elephant grass cv. BRS capiaçu silage with increasing proportions of silk cotton. A completely randomized design was used with five (0, 15, 30, 45, and 60% on natural matter basis) different inclusion proportions of silk cotton to elephant grass silage and four repetitions. Silages were prepared in PVC minisilos and remained ensiled for 42 days. The inclusion of silk cotton resulted in a linear reduction in dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose, and indigestible neutral detergent fiber (iNDF) contents at 0.06, 0.30, 0.23, 0.20, and 0.09 percentage points for each 1% inclusion, respectively. There was an increasing linear effect of crude protein (CP) and total digestible nutrients (TDN), with an increase of 39.32 and 20.89% from the lowest to the highest inclusion of silk cotton to elephant grass cv. BRS capiaçu silage. Values of pH, gas losses (GL), effluent losses (EL), dry matter recovery (DMR), hemicellulose, and lignin were not influenced by the evaluated inclusion levels, showing estimated averages of 3.87, 1, 42%, 11.55kg t-1 natural matter, 97.36%, 19.30%, and 7.20%, respectively. An increasing linear effect was found for fraction a, c, effective degradability (ED) (2% and 5%) dry matter, with an increment of 0.05, 0.0005, and 0.11 percent points, respectively. There was a quadratic effect for fraction b, potential degradability (PD), ED (2%), with minimum points of 23.72%, 50.52%, (at 45% inclusion level) 39.69%, (at 15% inclusion level) respectively. The indigestible fraction (IF) had a quadratic effect with a maximum of 49.48% at the 45% inclusion level. The colonization time (CT) linearly reduced by 0.09 percentage points for each 1% inclusion evaluated. According to the parameters evaluated, the inclusion of up to 60% silk cotton improved nutritional aspects and nutritional value of elephant grass cv. BRS capiaçu silage.

Inclusion Level

The aim of this study was to evaluate the fermentative losses and nutritional value of elephant grass silages with the increasing of inclusion levels of dehydrated banana peel. The experiment was conducted in a completely randomized design, with six treatments and four replications, being the silage exclusively from elephant grass, and five levels of inclusion of banana peel to the elephant grass silage, as the following - 5; 10; 15; 20 and 25%, being added based on natural matter. The addition of the banana peel in the silage reduced linearly (p < 0.05) the pH, the ammoniacal nitrogen and the losses of the fermentative process. In addition, the inclusion of banana peel increased linearly (p < 0.05) the dry matter and non-fibrous carbohydrates. On the other hand, the neutral detergent fiber and the acid detergent fiber were linearly reduced with the inclusion of the banana peel (p < 0.05), but there was no change in the dry matter digestibility in situ. The inclusion of dehydrated banana peel in elephant grass silage reduces the losses of the fermentation process with more consistent results at the 25% inclusion level, however, it reduces the silage nutritional value due to fibrous and protein quality.

The experiment was conducted to determine the effects of three additives (molasses, cracked corn and corn-soybean) and inclusion levels (0, 2.5, 5, 7.5 and 10 %) on nutritive value of elephant grass (Pennistum purpureum) silage. The experimental design was a 3×5 factorial in a completely randomized design with each treatment replicated three times. Samples were obtained from Pasture Museum. Elephant grass stands at late vegetative stage were randomly selected and harvested at 7 cm stubble height. Grass was chopped into 2-3 cm length. Five hundred gram of the sample was weighed in each case; additives were added separately at the designated inclusion levels and mixed thoroughly. Materials were then tightly packed into laboratory silos compressed and sealed tightly and left for a fermentation period of 21 days. The results indicated crude protein (CP) was significantly greater (10.92%) in silage treated with corn-soybean additive compared with other additives. Crude fiber (CF) was observed to be lower in molasses treated elephant grass silage (27.74 %). Acid detergent fiber (ADF) and neutral detergent fiber (NDF) were both lower in molasses treated silage (24.76 and 43.26 % respectively). The CP was observed to increase with increased inclusion level of the additive while CF decreased. Values for digestible dry matter (DDM), dry matter intake (DMI)as a percentage of body weight and relative feed value (RFV) were greater (P<0.05) in molasses treated silage compared to corn and corn-soybean. The DDM, DMI and RFV values were higher (P<0.05) at 7.5 and 10 % inclusion levels. Significant interactions were observed between additives and inclusion levels in most parameters measured. It was concluded that molasses additive could be used in elephant grass silage during ensiling at 7.5-10 % levels of inclusion.

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 objective of this research was to evaluate the effect of three concentrations (3, 6, and 9%) of forage turnip (Raphanus sativus) and physic nut (Jatropha curcas) cakes on dry matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, lignin, acid detergent insoluble nitrogen neutral detergent insoluble nitrogen contents, in vitro dry matter digestibility, pH values and concentrations of N-NH3 in elephant grass silages. It was used an entirely randomized design in factorial arrangement [(2×3)+1]. Experimental PVC silos were used and ensiled material was kept for 62 days. The addition of cakes increased the dry matter contents (P<0.05). The fibrous fractions were reduced (P<0.05) with the inclusion of cakes during the grass ensilage and the CP contents increased (P<0.05). The forage turnip cake provided the same pH and N-NH3 values in ideal levels and the physic nut, added to 9%, increased those values (P<0.05). IVDMD was reduced (P<0.05) when the cakes were added. These co-products can be used in small amounts for elephant grass ensilage in order to provide improvement in chemical and fermentation characteristics of the silages. Nevertheless, physic nut cake shows limitations for its use in animal feeding due to the presence of toxic compounds, making necessary studies for their identification and elimination.

Fermentation Profile

The objective of this research was to evaluated the inclusion of buriti fruit peel as additive on the fermentation profile, losses, chemical composition and degradability of elephant grass silage. We used a completely randomized design with five levels of buriti fruit peel (0, 50, 100, 200 and 400 g kg-1). The silos were opened after 28 days of storage. In situ degradability monitoring was conducted using a split-plot design in which four animals represented the blocks and silage supplemented with five levels of buriti fruit peel represented the treatments. The use of the additive in elephant silage increased dry matter (DM) (P < 0.001), ether extract (EE) (P < 0.001), ash (P < 0.001), neutral detergent fiber (NDF) (P < 0.001) and acid detergent fiber (ADF) (P= 0.0000). The pH (P= 0.0000), N-NH3 (P = 0.024) and there was a decrease in gas losses (P < 0.001), effluent losses and dry matter recovery (P = 0.218) not were influenced by the addition of buriti fruit peel. The inclusion of buriti fruit peel linearly reduced the ruminal degradability DM of soluble fraction (a) (P < 0.001) and potentially degradable insoluble fraction (b) (P < 0.001). The DM content increase with the addition of the buriti fruit peel to the elephant grass silage promotes improvements in the fermentation process, reduces losses of nutrients and ruminal disappearance of dry matter and does not significantly change the chemical composition with the inclusion of 166.7 g kg-1 of the buriti fruit peel.

 The objective of this study was to evaluate in situ ruminal degradability of elephant grass silages with addition of 8, 16 and 24% of faveira pods in experimental silos of 100x50 mm, equipped with bunsen valves. The content of crude protein (cp) and neutral detergent fiber (ndf) were determined on a dry matter basis. To evaluate the in situ degradability of dm, cp and ndf, nylon bags containing 4 g sample were incubated in the rumen of three fistulated cattle for 6, 24 and 72h. The dm and cp content of elephant grass silages increased (p < 0.05) from 8% inclusion associated with a higher concentration of constituents in faveira pods (77.25 and 9.61% dm). The ndf fraction reduced 10.91% (p < 0.05) when adding 24% pods. The potential degradation (pd) of dm and cp increased with inclusion of faveira pods, with 75.97 and 95.21%, respectively, for the level of 24%. There was increased potentially degradable fraction (bp) of ndf by 7.07% with inclusion of 24% faveira pods, as well as a reduced colonization time (lag) from 3.81 to 3.44 hours. The addition of up to 24% faveira pods to elephant grass silages improves rumen microbial degradation, and it is indicated this level of addition to obtain better quality silage.

The objective of this study was to evaluate the nutritive value of elephant grass silages with increasing levels of dried mango by-product (DMB). Five addition levels were studied (0, 4, 8, 12 and 16%) using 20 rams, in a randomized complete design with five treatments (addition levels) and four replications. 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) intake and digestibility were evaluated, as well as the total digestible nutrients (TDN) and the silage nitrogen balance (NB). Mango by-product addition did not influence the DM, CP and TC intakes, the TDN level or the OM, CT and NFC digestibilities. On the other hand, DMB addition reduced the NDF and the ADF intakes, as well as the DM, CP, NDF and ADF digestibilities, and the NB of the silages. There was also a increasing linear effect of DMB addition on the EE and NFC intakes, and on EE digestibility. The elephant grass silage with DMB by-product may not be used as a single feed to ruminants because it reduces the NDF and the ADF intakes and the DM, CP, NDF and ADF digestibilities, as well as the nitrogen balance.

The aim of this study was to evaluate the effect of ammoniation by urea on the nutritional value of elephant grass hay harvested after flowering. A completely randomized design, in double factorial designs with an additional treatment: 4 urea doses (2, 4, 6 and 8%) x 2 treatment periods (30 and 45 days) + 1 (Control) with four replicates each, was employed. Dry matter, ash, ether extract, neutral detergent fiber, acid detergent fiber, cellulose, lignin, neutral detergent fiber corrected for the ash and the protein, total nitrogen, acid detergent insoluble nitrogen, neutral detergent insoluble nitrogen, non-protein nitrogen, in vitro gas production and carbohydrates fractionation were analyzed. The treatments influenced the contents of DM, EE, NDF, ADF, lignin, cellulose, NDFap, fraction A + B1, fraction B2, fraction C, TN, NPN, ADIN, NDIN, L and Vf2. There was a positive linear effect of urea dose for NDF, ADIN, NDIN and L, positive linear effect on fraction A + B1, NT and NPN, and positive quadratic effect for Vf2, with absolute maximum point of 4.5%. Elephant grass hay harvested after flowering has its nutritional value improved, with a minimum dose of 4.5% urea on a dry matter basis.

This study evaluated the feeding behavior of F1 Holstein x Zebu cows fed increasing levels of banana peel. Diets contained 0, 15, 30, 45 and 60% replacement of sorghum silage with banana peel. The experimental design was two 5x5 Latin squares. Cows were subjected to visual observation after adaptation of each trial period. The times spent in feeding (4.13 to 5.58 hours day-1) and in idle (10 to 12.53 hours day-1) presented quadratic effect. The time spent ruminating, number and duration of rumination periods, chews per cud, and numbers of cuds per day were not affected by treatments. The total chewing time showed a quadratic effect, with peak at 18.58% replacement. The banana peel levels did not affect consumption, rumination and chewing neutral detergent fiber. Intake, rumination and chewing of dry matter showed a decreasing linear effect. The replacement of sorghum silage with banana peel up to 60% in the diet for lactating cows reduces the time spent in feeding and improves feeding and rumination efficiencies of dry matter, keeping the milk production of cows.

The aim of this study was to evaluate the addition of macauba palm cake (Acrocomia aculeata) on the chemical composition, fermentation and aerobic stability of elephant grass silages (Pennisetum purpureum). The experiment was performed in a completely randomized design with four replicates. The treatments were composed of six levels of macauba palm cake (0, 6, 12, 18, 24, 30%) as additive to elephant grass silage. Dry matter and ethereal extract content of the silage increased linearly with the inclusion of the additive. Addition levels of 15.54% would provide 35% of dry mass, and the limit of 7.00% of ethereal extract in the silage could be obtained with 10.47%. The neutral detergent fiber content reduced linearly from 68.97 to 52.59%, but lignin increased linearly from 6.56 to 7.70%. There was a reduction of 0.17% in the ammoniacal nitrogen content for each 1% of cake. The minimum value of dry matter losses (1.33%) was estimated to the inclusion level of 23.70%. The aerobic stability increased with inclusions between 18 and 24% of cake. The use of levels between 10 and 15% of macauba palm cake are sufficient to optimize dry matter and ethereal extract contents of the silages and to provide a high aerobic stability with minimum losses.
