An experiment was conducted to determine the biomass yield, chemical composition and in-sacco dry matter (DM) degradability of 10 cultivars (WRF-7, TSN-111, TYT-03, TYT-05, TYT-06, TYT-08, TYT-12, ITYN-10, ITYN-14 and ITYN-15) of triticale fodder. The fresh yield of different cultivars of triticale was ranged from 5.03 to 6.85 (t/ha). The organic matter (OM), crude protein (CP), acid detergent fibre (ADF), neutral detergent fibre (NDF), calcium (Ca) and phosphorus (P) contents of different cultivars of triticale were found 89.62 to 91.78 %, 21.34 to 25.99 %, 23.09 to 29.99 %, 46.77 to 50.80 %, 0.42 to 0.61 % and 0.33 to 0.41 %, respectively. The yield of DM and CP of different cultivars of triticale were varied from 0.77 to 1.44 (t/ha) and 0.193 to 0.351 (t/ha), respectively. Among different triticale cultivars the highest OM and CP contents were found in TYT-12 (91.78 %) and ITYN-10 (25.99 %), respectively. The highest NDF and ADF contents were found in ITYN-14 (50.80 %) and TYT-05 (29.99 %), respectively among different cultivars. The contents of Ca and P in ITYN-10 (0.61 %) and ITYN-14 (0.41 %), respectively were found to be the highest among the cultivars. Potential DM degradability observed in different cultivars of triticale was higher in ITYN-14 and TYT-05 (84.81 and 81.88 %, respectively) compared to others and relatively poor degradability was found in TSN-111 and TYT-03 (60.74 and 61.35 %, respectively). Therefore, it may be concluded that, the cultivar ITYN-10 will be the promising one due to comparatively higher fresh yield, organic matter (OM), crude protein (CP), neutral detergent fibre (NDF), calcium (Ca) and phosphorus (P) content and less acid detergent fibre (ADF) fraction cultivated for fodder production in Bangladesh.http://dx.doi.org/10.3329/bjas.v41i1.11972

Ad Libitum

Chopped lucerne hay (Medicago sativa) and a stem fraction derived from it were fed to two adult and two immature wethers ad libitum and at a level near maintenance. Energy, nitrogen, and carbon balances were measured during feeding and fasting. The hay contained 17% crude protein and 46% cell wall constituents (dry matter basis) and the stem, which was 53% of the total, contained 10% crude protein and 64% cell wall. Voluntary dry matter consumption rates of the hay (per kg 3/4) were 103 and 145 g/day by the adults and immatures, respectively; the corresponding values for the stem were 73 and 100 g/day. Maximum daily energy balances were 290-3 16 kJ/kg3/4 for the hay and approximately maintenance for the stem. With both ad libitum and restricted feeding, energy digestibility was higher for the hay (56- 63%) than for the stem fraction (45-51%). The metabolizable fraction of digestible energy was 78% at the low and 82% at the high level of feeding and tended to be greater with the stem than with the hay. At the lower feed intake, metabolizable energy was about 10 and 8 MJ/kg organic matter for whole lucerne and stem respectively. Net availability of metabolizable energy was 64 and 49% for maintenance and gain on the hay, compared with 53 and 34% on the stem. As estimated by difference, the energy values of leaf were: digestible energy, 76%; metabolizable energy, 77% of digestible energy or 12.4 MJ/kg organic matter; net availability of metabolizable energy, 78% for maintenance and 60% for gain. All these figures are for the adult sheep; the immature animals gave values that were lower to various degrees. Consideration of the present results together with published data for other samples of lucerne suggests that the use of equations based on study of grasses to predict the energy values of lucerne is likely to introduce significant bias. Equations for this limited set of data on lucerne are given, gross energy being related to crude protein content, metabolizable energy to crude fibre and net availability of metabolizable energy to metabolizable energy content.

Voluntary Intake

Data are reported on the voluntary intake and digestibility by sheep of five species of Digitaria when grown as swards, cut at five different stages of growth and analysed for neutraldetergent solubles, hemicellulose, cellulose, lignin, N, S, Na, K, P, Ca, Mg, Si, Cu, Mn, and Zn. Digitaria setivalva was superior to the other four species in in vivo digestibility of the dry matter, organic matter and energy (5.2 percentage units), content of metabolizable energy (5.3%), voluntary intake of dry matter (8 0%) and voluntary intake of metabolizable energy (18.1 %). This superiority was associated with a higher content of digestible neutral-detergent solubles and cellulose. The metabolizable energy contents of the grasses were significantly correlated with dry matter digestibility and organic matter digestibility, content of digestible dry matter and concentrations of crude protein, neutral-detergent fibre, acid-detergent fibre, lignin and combinations of these different fractions.

Detailed Work

SUMMARYThe nutritional value of dried poultry excreta was investigated by determining the apparent digestibility of dry matter, organic matter, nitrogen, energy and copper in five diets containing 0 to 100% of this feed. Dried poultry excreta supplied 20·21% apparently digestible crude protein and approximately 1·57 or 1·74 Mcal of metabolizable energy per kg dry matter.The copper in dried poultry excreta was found to be less digestible than the copper in barley. It is concluded that, as far as copper levels are concerned, dried poultry excreta are safe for ruminants, and are a source ofcheap protein. More detailed work is needed to determine the metabolizable energy of the material accurately.

This study planned to determine the differences among nutrient composition, in vitro digestibility, energy content, digestible dry matter and organic matter yields of barley forage harvested at three different stages of maturity. Each vegetation period (heading stage, seed formation stage and mature stage) was randomly assigned to 5 replication from 1 square meter area and fifteen samples were harvested in total. DM, ADF (p<0.001), and NDF (p<0.05) contents were different in each stages of barley forage. In vitro dry matter (IVDMD), organic matter digestibility (IVOMD), metabolizable energy (ME), and net energy for lactation (NEL) values of samples were determined to be lower than the other two stages at the mature stage (p<0.05). Yield parameters of barley were significantly affected by vegetation period (p<0.001). It can be concluded that all three vegetation period had significantly higher digestibility. Digestible DM, OM and energy yields were higher when harvested at the mature stage of vegetation.

Feedblocks, poultry manure diet, gliricidia: leucaena mixture (1:1 W/W) and maize offal diet were compared as sources of protein supplements for WAD sheep fed a basal diet of elephant grass hay (Pennisetum purpureum), through a 12-week performance and digestibility study. Dry matter and organic matter intakes (DMI, OMI) of the sheep were higher (P0.05) on the gliricidia: leucaena supplement than on the other diets. DMI on poultry manure and maize offal diets were not significant (P0.05). Organic matter intake (OMI) of the animals followed the same trend as DMI. Sheep fed legume supplements excelled in intakes of crude protein (CP), acid detergent fibre (ADF) and digestibilities of dry matter (DM), organic matter (OM) and neutral detergent fibre (NDF) (P>0.05). Intakes of CP and ADF by sheep on the other supplements were not significantly different (P>0.05). Sheep fed on feedblock supplement consumed the least amount. (P0.05) of NDF. Variations were observed in DM,OM, and NDF digestibilities by sheep on maize offal, poultry manure and legumes supplements. Crude protein digestibility in the legumes and feedblocks supplements was higher (P0.05) than with the other two supplements. All the sheep used gained weights but those on maize offa' diet recorded higher (P0.05). weight gain (86.57g) than those on browse leaves (59.40g), feedblocks (47.80g) and poultry manure (40.44g). Rumen pH was lower (P<0.05) on the gliricidia: leucaena supplement than on other diets. Total VFA recorded for sheep on maize offal diet and legumes supplements was higher (P<0.05) than for the other two supplements. Blood urea nitrogen of the supplements were not significantly different (P>0.05)

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.

Results obtained from 45 sheep metabolism trials, involving 190 sheep periods, with 11 different pasture types were analyzed to determine equations for the prediction of energy content, energy digestibility and digestible energy content. Independent variables considered in the analyses were crude protein and normal acid fibre contents and dry matter, organic matter and normal acid fibre digestibilities. In all equations significant pasture type effects were detected. The importance of these effects are discussed with particular consideration of likely biases that may result and the errors of prediction associated with overall regressions. The regressions obtained in this study are compared with a number of others reported in the literature.

AbstractA study was conducted to compare the digestibility of organic matter (OM), neutral-detergent fibre (NDF), acid-detergent fibre (ADF), hemicellulose and nitrogen (N) and N balance in Mukota (M), Large White (LW) and the LW × M F1 pigs. Four male pigs of each breed, at proportionately 0·3 of their mature body weights, were randomly allocated to each of four diets in a cross-over design. The diets, which were formulated to contain similar levels of protein (ca. 160 g crude protein per kg) and energy (ca. 9 MJ metabolizable energy per kg), contained 0, 100, 200 and 300 g maize cob meal per kg, which corresponded to NDF levels of 276·4, 360·3, 402·9 and 523·5 g/kg dry matter, respectively. There was a negative correlation (P < 0·001) between the digestibility of OM, NDF, ADF and hemicellulose and the level of NDF in the diet. The digestibility of OM, NDF, ADF and hemicellulose decreased linearly (P < 0·05) with increase in the level of NDF among all three genotypes. There was a genotype × diet interaction on NDF and ADF digestibilities with digestibility in the LW decreasing faster (P < 0·05) than in the Mukota and LW × M F1 cross with increasing NDF. Both breed and level of maize cob meal affected N digestibility (P < 0·001), whilst the N retained per unit metabolic body weight was only affected by diet (P < 0·01). Increasing the level of maize cob meal beyond 100 g/kg, however, did not reduce N digestibility (P < 0·05). There was neither genotype nor dietary effect (P > 0·05) on N retained per unit N intake. These findings showed that the Mukota and the LW × M F1 cross were better able to digest the fibrous components than the LW. In addition, the Mukota and the LW × M F1 cross displayed an ability to retain protein to the same extent as the LW.
