The effect of processing on proximate, mineral, anti-nutritional compositions, gasproduction characteristics, methane production, predicted metabolizable energy, organic matter digestibility and short chain fatty acids production of Delonix regia seeds incubated with Pennisetum purpureum were determined. Five treatments (T1: mixture of soaked Delonix regia seed and Pennisetum purpureum; T2: mixture of raw Delonix regia seed and Pennisetum purpureum; T3: mixture of roasted Delonix regia seed and Pennisetum purpureum; T4: mixture of boiled Delonix regia seed and Pennisetum purpureum and T5:100% Pennisetum purpureum which serves as control) were designed. In vitro gas production techniques for 24 hours were used to determine the nutritive value of processed 50% Delonix regia seed and 50% Pennisetum purpureum. The crude protein ranged from 13.38 to 15.71g/100g DM among the treatments while crude fibre was between 20.10 and 21.40g/100g DM, ether extract ranged from 1.90 to 3.12g/100g DM and ash 7.77 to 12.34g/100g DM. Calcium ranged from (2.34 - 3.61%), magnesium ranged (2.90 – 3.48%), sodium (2.05 – 2.91%) and phosphorus (0.88 – 1.12%). It was observed generally that T2 recorded the highest among the treatments while the values obtained for the heat treated seeds were lower than the raw. Oxalates ranged between (0.23% - 0.32%), phytates (0.29 – 0.43%), tannin (0.03 – 0.08%) and saponnin (0.36 – 0.49%). Methane (ml/200mg DM) production indicated T3 (50% roasted Delonix regia seed and 50% Pennisetum purpureum) was highest. The potential gas production 'a+b' ranged from 12.33 to 28.33mL/200mg DM). The highest potential gas production 'a+b' value of 28.33mL/200mg DM was obtained in T1 compared to other dietary treatment. Dry matter digestibility (DMD) ranged between 70.23 – 91.02% while the rate of fermentation was between 0.51 and 1.18ml/hr. The rate of fermentation was directly proportional to dry matter digestibility (DMD); the soaked recorded the highest value. Processing enhanced the nutritional contents of Delonix regia seeds. The result obtained showed that there were significant differences (p<0.05) among the treatments. In conclusion, soaking the seeds of Delonix regia had beter nutritional contents and has the potential for dry season feeding.

SUMMARYThe current study was conducted to determine chemical composition, nutrient content and availability, metabolizable energy (ME) content and nutritive value of sainfoin hay for ruminants. Three ruminally cannulated Holstein cows were used forin situandin vivoexperiments, to determine rumen degradability and digestibility of sainfoin hay. Apparent total tract digestibility of nutrients was determined with feeding of sainfoin hay as the sole diet to achieve 10% more than maintenance energy requirements. Six Zandi ewes were used in the palatability experiment. Means for dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF) and condensed tannins (CTs) of sainfoin hay were: 940·4 g/kg and 93·43, 12·13, 47·87, 43·33 and 2·13 g/kg DM, respectively.In situeffective degradability of CP and DM were 0·38 and 0·54 g/g with a ruminal outflow rate of 0·05/h, respectively. OM apparent digestibility was in the range of 0·592–0·689, respectively, for Tilley & Terry and total faecal collection assays. ME content of sainfoin hay, according to different methods (gas production,in vitroandin vivodetermined digestible organic matter in dry matter (DOMD)) was in the range 6·87–10·11 MJ/kg DM. Metabolizable protein (MP) content was 483·4 g/kg CP. Sainfoin was more palatable than alfalfa for sheep. It was concluded that sainfoin has a potential use in ruminant rations, especially if environmental conditions are not suitable for alfalfa production.

SUMMARYA rapid method for measuring gas production during incubation of feedingstuffs with rumen liquor in vitro is described. Gas production in 24 h from 200 mg feed dry matter was well correlated with digestibility of organic matter, determined in vivo with sheep. Multiple regression analysis, when it included data from proximate analysis, resulted in an equation (R = 0·98) for prediction of metabolizable energy content, based on 30 experiments with rations varying in protein and crude fibre content, and 59 other experiments with concentrates. Energy content was in the range of 7·7–13·2 MJ ME/kg D.M. (± S.D. = 11·17 ± 1·08). The residual standard deviation of the equation was 0·25 MJ. Gas production was measured in calibrated syringes. The only chemical determinations needed are dry matter, protein and fat. Differences in activity between batches of rumen liquor are corrected by reference to gas production with standard feedingstuffs (hay meal and maize starch).

Tridax Procumbens

Studies were conducted to evaluate the nutritive value of eight selected forages (Tridax procumbens, Merremia aegyptia, Aspilia africana, Tithonia diversifolia, Alchornea cordifolia, Alchornea laxiflora, Synedrella nodiflora, and Newbouldia laevis) consumed by ruminants in South-Western Nigeria. Chemical composition and qualitative analysis of saponins, phenol and steroids of the plants were determined. In vitro gas production (IVGP) was carried out for 72 hours on the plants. Metabolizable energy (ME), Organic matter digestibility (OMD) and Short chain fatty acids (SCFA) were predicted and methane (CH4) was measured. Five of the plants were subjected to acceptability study using cafeteria method. The result of the chemical composition revealed that M. aegyptia had the highest value of CP (22.09 %) while Tridax procumbens had the lowest (10.50 %). A. africana had the highest content of Calcium, Phosphorus and Zinc with values of 3.10 %, 0.93 % and 39 ppm respectively. The analysis of secondary metabolites showed that A. africana, T. diversifolia and S. nodiflora were high in saponin while A. cordifolia, A. laxiflora, T. diversifolia and A. africana were implicated for condensed Tannin. N. laevis recorded a high level of steroids. Results showed significant variations in the values of IVGP, ME, OMD, SCFA and CH4 obtained for the plants. The order of preference of the plants by the calves were M. aegyptia>A. cordifolia > N. laevis > A. axiflora> T. diversifolia. The study revealed that the forages are rich in crude protein as well as micro and macro minerals. They are also rich in highly fermentable carbohydrates which affirm them as ruminant feed resource.

An experiment of treated and ensiled wet rice straw with urea and molasses was performed to explore the chemical composition, physical quality, in vitro digestibility and its potentiality as a quality feed for ruminants. In this experiment, plastic containers were used to preserve chopped wet rice straw under airtight condition based on the treatment as T1 (wet rice straw only), T2 (straw with 5% molasses), T3 (straw with 5% urea), T4 (straw with 5% urea and 5% molasses) and T5 (straw with 10% urea and 5% molasses) to analyze chemical composition, physical quality, metabolizable energy (ME) content, in vitro organic matter digestibility (OMD) and in vitro gas production (IVGP) at five different ensiling times of 0, 30, 45, 60 and 90 days. The physical quality (color, smell, softness characteristics) of wet rice straw was improved with urea and molasses treatment. Treatments T5 was found better as there was no fungal growth till 90 days of ensiling. The addition of urea and molasses improved the physical quality, nutritive value and preservation quality of wet rice straw. Urea and molasses treated and ensiled (T5) straw showed better color, nutritional quality, softness and longer preservation capacity compared with all treatments followed by T4, T2 and T3. The crude protein (CP) content was increased (P<0.05) but the crude fibre (CF), dry matter (DM), ash contents and ether extract (EE) were decreased (P<0.05) in all of the treatments (T2, T3, T4 and T5) compared to control (T1). The OMD, IVGP and ME contents were increased in all of the treatments (T2, T3, T4 and T5) compared to control (T1). The highest OMD, IVGP and ME values were observed in treatment T5 and the lowest values were in control (T1) Through the Consideration of all the chemical and physical properties, among all of the treatments, 10% urea and 5% molasses are found acceptable for the preservation of rice straw. Thus, environment friendly and cost effective feed can be formulated.

Sorghum Sudangrass

Sorghum-sudangrass hybrid silage has poor fermentation characteristics owing to a high moisture content. Accordingly, a 3 × 4+1 factorial design was applied to investigate the effects of adding different types and amounts of hay (corn stalk, wheat straw, and alfalfa hay at 12.5 kg t-1, 25 kg t-1, 37.5 kg t-1, and 50 kg t-1) on the nutritive value, fermentation quality, 72 h dry matter digestibility, and gas dynamics in vitro to simulate the rumen fermentation of sorghum-sudangrass hybrid silage. Separated silage of sorghum-sudangrass hybrids had a high butyric acid content and a FLIEG’s scores evaluation ranking of only “Fair.” The addition of hay significantly improved the fermentation quality of mixed silage. With respect to hay type, adding wheat straw had the best fermentation quality, alfalfa hay had the best nutritive value, in vitro dry matter digestibility (IVDMD) (662.41 g kg-1), constant fractional rate (C) (0.28 mL h-1), and the average gas production rate (AGPR) (32.70 mL h-1) content. There were no differences in the cumulative gas production at 72 h (GP72h), asymptotic gas production generated at a constant fractional rate (A), and lag time before gas production commenced (lag) among the three hay types. With respect to quantity, 25 kg t-1 hay had the best fermentation quality, 50 kg t-1 hay had the best nutritive value and highest IVDMD content (662.81 g kg-1), 37.5 kg t-1 hay had the highest C (0.28 mL h-1) and AGPR (31.48 mL h-1) contents, 25 kg t-1 hay had the highest Half time (2.20 h), and there were no significant differences in GP72h, A, and lag among the four amounts. Considering both nutritive value and fermentation quality, the best mixed silage mode was 37.5 kg t-1 wheat straw.

AbstractThe aim of this study was to determine the in vitro digestibility and in sacco disappearance of dry matter (DM) and neutral detergent fibre (NDF) in total almond hulls (TAH), pure almond hulls (PAH) or Debris. The TAH were used because there are no data on the effect of debris (non-hull material) on the nutritional value of almond hulls. Twelve samples of commercial almond hulls were used, with one subsample representing the TAH and the other subsample hand sorted to separate the hulls (PAH) from Debris. Gas production and Ankom Daisy method were used to determine in vitro digestibility, while two rumen-fistulated cows were used to measure in sacco disappearance of PAH and TAH. For in vitro digestibility, both PAH and TAH were more digestible and had greater gas production than Debris. The PAH had greater in vitro true digestibility on a DM basis and NDF digestibility at 48 and 72 h compared with TAH. Nonpareil hulls provided greater metabolizable energy (ME) concentration when compared with other almond varieties, with PAH supplying numerically more ME than TAH for both varieties. For in sacco disappearance, PAH had greater DM and NDF disappearance along with a greater rate of disappearance for NDF compared with TAH. This research demonstrated that Debris is highly indigestible; therefore, hulling, agronomic and harvesting practices should be focused on reducing Debris in commercial almond hulls to improve their nutritive value as a feedstuff for livestock.

The study was aimed to evaluate the associative effects of mixtures of stylosanthe (Stylosanthes guianensis) and king grass (Pennisetum purpureum × P. americanum cv. Reyan No. 4) silage at different ratios using in vitro gas production technique. Three stylosanthes (S. guianensis Sw. Reyan No.2, S2; S. guianensis Sw. Reyan No.20, S20; S. guianensis Sw. Reyan No.21, S21) were mixed with king grass silage (K) at different ratios (0:100, 10:90, 20:80, 40:60, 50:50, 100:0) and their associative effects were evaluated using in vitro gas technique. The results showed that under the controlled conditions, addition of the mixtures of stylosanthes and king grass silage could improve in vitro gas production (GP), in vitro dry matter digestibility (IVDMD) and microbial protein (MP) and promote the vitality of rumial microbes. In addition, most mixtures of stylosanthes and king grass silage showed positive associative effects and the mixtures at ratio of 20:80 had the best associative effect based on the synthetically associative effects index (SAEI).

Digestibility is a description of the ability of feed material that can be utilized by livestock. Higher digestibility of feed material means the total amount of feed content that can be digested in the digestive tract. This study aimed to obtain the proportion of the use of fermentation concentrate in rumen fermentation based on in vitro. The feed used consisted of 7 treatments as follows P1 (20% Pennisetum purpureum: 80% concentrate), P2 (30% P.purpureum : 70% concentrate), P3 (40% P.purpureum : 60% concentrate), P4 (50% P.purpureum : 50% concentrate), P5 (20% concentrate: 80% P.purpureum), P6 (30% concentrate: 70% P.purpureum) and P7 (40% concentrate: 60% P.purpureum). Dry matter digestibility (DMD) and organic matter digestibility (OMD) were done using Theodorou method. Gas production was measured when the samples were incubated at 39oC in the waterbath incubator at hours 2, 4, 6, 8, 10, 12, 24, and 48. Approximately 0.75 g of feed formulation was mixed with 75 mL of rumen fluid buffer. The rumen fluid is taken from 3 fistulated cattles prior to morning feeding. A complete randomized design with three replicates was used. Asymptotic gas production and kinetics were estimated by the Orskov’s model. The results of this study showed that P2 and P3 treatment showed the best digestibility among others treatment with 71.63% ; 71.06% of DMD and 76.42% ; 71.65% of OMD. In conclusion, P2 and P3 treatment can be used as feed for beef cattle.

The ruminants in the tropics are slow growing, arising from low quality feed. The use of indigenous legume trees and Guinea grass is a good strategy for an improved livestock performance. The study determined the chemical composition, anti-nutritional factors and in vitro gas production characteristics of Panicum maximum-Moringa oleifera mixed diets. Five diets were formulated such that Panicum maximum was substituted with Moringa oleifera at ratio 0, 25, 50, 75 and 100% in diets A, B, C, D and E respectively and they were incubated for 48 hr using in vitro gas production technique. The proximate composition, fibre franction, anti-nutrient, mineral contents and in vitro characteristics of the P.maximun M.oleifera mixed diets were determined and all data collected were subjected to one way analysis of variance and where there were significant (P<0.05) differences, means were compared using Duncan multiple range F-test. The results revealed that the observed values were significantly (p<0.05) influenced by the inclusion of Moringa oleifera in the diets with the exception of dry matter and gross energy. Dry matter values (87.00-89.72g/100g) decreased with the increased inclusion of Moringa oleifera in the diets, while protein content (9.26-26.68g/100g) increased with the increased inclusion of Moringa oleifera in the diets. It implied that the diets could be good sources of protein and energy that would meet the requirement of small ruminants for growth and production. Neutral detergent fibre and Acid detergent lignin values decreased with the increased inclusion of Moringa oleifera in the diets. However, the values of acid detergent fibre, hemicelluloses and cellulose ranged from 20.13 to 43.44g/100g, 6.88 to 14.45g/100g and 14.65 - 31.48g/100g respectively. Anti nutrient values were significantly (p<0.05) influenced by the treatment. Tannin concentrations in these diets were below the 6.00g/100g toxic level for small ruminants. The concentrations (g/100g) of Ca (0.12.-2.74), P (0.05 – 0.12), K (0.17 -2.78). Na (0.07 - 0.27), Fe (0.07 -0.17) and Zn (0.04 -0.16 ) varied significantly (p<0.05), the observed values were higher in diet E that contained 100% Moringa oleifera leaves than other diets. The high contents of these minerals in Moringa oleifera indicated that the requirements of sheep and goats for these minerals could be met if the plant is fed with grass ad libitum. There were significant (p<0.05) differences among the treatment means of metabolizable energy (ME 3.44-5,58 MJ/kg DM), organic matter digestibility (OMD 30.96-43.65 g/100g), short chain fatty acids (SCFA 0.05 -0.26 µmol) and methane (2.00 - 6.00 ml). Total gas and methane production increased with incubation period and the highest values of OMD was observed in the 48th hour of incubation. It can be concluded that with the enhanced values of crude protein, gross energy, metabolizable energy, short chain fatty acids and low methane production, the Panicum maximum-Moringa oleifera diets have potential that would meet the nutrient requirements of small ruminants in the tropical regions particularly during the dry season.

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.
