The nutritive value of barley-derived distillers dried grains (BDDG) and distillers dried grains with solubles (BDDGS) was assessed in digestibility and in sacco rumen degradability experiments. The crude protein contents of BDDG and BDDGS were 26.4 % and 29.9 %, and the crude fibre contents 19.9 % and 17.4 % in DM, respectively. The ADF and NDF contents averaged 33 % and 67 % and the lignin 7.6 % of DM. The digestibilities of the nutrients were measured with four rams in both trials and the distillers by-products were given at two levels, 33 % and 66 %, in hay-based rations. The digestibilities in BDDG and BDDGS were, respectively, 43.1 % and 47.7 % for organic matter, 64.5 % and 66.5 % for crude protein, and 86.7 % and 87.9 % for ether extract. Due to the low digestibilities, the energy values of the two products were low, 0.58 FU/kg DM and 8.0 MJ/kg for both, and DCP/FU 295g for BDDG and 347 g for BDDGS. The rumen degradability of the crude protein of BDDG and BDDGS was found to be low and significantly lower than the degradability of wheat distillery by-products (P < 0.05). Fine grinding gave more rapid degradability. Due to the low total digestibility and reduced lysine content, BDDG and BDDGS may have limited protein availability when given as supplements.

Dried spent hops possess a high absorptive capacity, and attention is drawn to its use as a “filler” to absorb such by-products as molasses and treacle.The material possesses a high crude protein value and its ether extract is very high for a fibrous food, while the amount of crude fibre is the same as in good meadow hay. There is a high percentage of mineral matter present.The digestibility of the material has been determined by feeding with hay chaff and linseed cake meal to three sheep. The spent hops were not readily eaten and could only be included in a ration in an amount equal to one-seventh of the dry weight of the total ration.Its digestibility is low, a fifth of the crude protein and the nitrogenfree extractives, one-half of the ether extract, one-twentieth of the crude fibre and one-fifth of the total organic matter only being digestible. The production starch equivalent was 24.5.

(1) A review of the literature on the digestibility of wheat by poultry revealed the fact that, whereas there appeared to be but little variation in the digestibility coefficients for organic matter and N-free extract, considerable variation existed in the digestibility coefficients for crude protein, fibre and ether extract. It was considered desirable, therefore, to carry out digestibility determinations of known varieties of English wheats in order to ascertain how far such variations could be attributed to different varieties of wheat having been used in these experiments.(2) Experiments carried out with Little Joss wheat and Yeoman II wheat gave closely concordant results for all nutrients other than ether extract.(3) The results obtained in these experiments support the view that the digestibility of crude fibre by poultry is negligible.(4) Except in the case of crude fibre and ether extract, poultry appear to be able to digest wheat as efficiently as other farm animals. Poultry are, however, distinctly inferior to other farm animals in their capacity to digest crude fibre and ether extract.(5) The results of the present experiment show general agreement with previous work, except in the case of protein, where the digestibility coefficients are distinctly higher than those hitherto recorded. The explanation of this result may possibly be sought for in the improved methods used in the estimation of uric acid and ammonia

The influence of the stage of maturity of alfalfa on the chemical composition and in sacco digestibility was studied in a laboratory experiment. Alfalfa plants were analysed in 8 vegetation stages harvested in regular intervals before the beginning of bud setting until the fall of blossoms. The contents of nitrogenous substances, fat, crude fibre, ADF, NDF, Ca, P, Na, K and Mg were determined in the samples, and using the in sacco method also the organic matter digestibility in the rumen. Further we assessed the energy content and calculated the N−free extractives (BNLV) value. In some stages the chemical changes were monitored in the whole plant. It was discovered that during vegetation there was a statistically significant increase in the crude fibre content and in the ADF and NDF fractions and a reduction in nitrogenous substances. A strong negative correlation was detected between the stage of maturity of alfalfa and content of crude protein and net energy for lactation (r = −0.97 and r = −0.92, respectively). In the individual stages of vegetation the differences in the content of nitrogenous substances, fibre and fat were statistically significant (P < 0.05). The statistically highest content of crude protein (28.97%) was detected in the first stage before bud setting and the lowest (11.97%) in the stage after the fall of blossoms. Later vegetation also had a stronger depressive effect on the content of fat and NEL. The organic matter digestibility (P < 0.05) was the lowest in alfalfa in the last stage of sampling (62.6%) when it reached a mere 85.99% of the digestibility at the beginning of bud setting. The highest organic matter digestibility (72.80%) was detected in a sample of young alfalfa prior to bud setting. In the experiment we confirmed a strong and negative correlation (r = −0.97) between the crude fibre content and organic matter digestibility. The correlation was also strong between the stage of maturity of alfalfa and the content of magnesium (Mg).

The nutrient digestibility and protein utilization of distillery feeds derived from dehulled barley, rye and wheat were studied with growing pigs receiving one of eleven diets in which the protein sources were BDDGS, RDDGS, WDDGS, BDDG, BDS or SBM. In a second trial BDDGS and BDDG were compared with the same feeds treated prior to cooking with cellulase enzyme. The diets, consisting of barley and distillers feed, were fortified with L-lysine and DL-methionine to achieve levels of 13.0 % DCP, 0.80 % lysine and 0.56 % S amino acids. The distillery by-products contained crude protein 24.8—41.5 %, crude fat 6.3—9.5 %, crude fibre 7.1 10.3 %, ADF 18.2—22.9%, NDF 33.3—43.7 % and ADL 8.7—11.3 % on a dry basis. Their lysine content was 0.43—1.36 % of DM and their S amino acid content 0.58—1.36 %. The digestibilities of organic matter and crude protein were 56—83 and 56—79 %. DDGS from rye had low digestibilities and barley distillers solubles high. The cellulase treatment decreased the OM and CP digestibilities by 6.4—10.4 and 15.3—15.4 % units, respectively. FU/kg DM varied from 0.63 to 0.84 and DCP from 177 to 405 g/FU. The N retention of the BDDGS, RDDGS, WDDGS, BDDG, BDS and SBM diets was, respectively, 21.7, 21.1, 24.2, 23.0, 17.7 and 24.6 g/d (P < 0.01) and the biological values were 55, 60, 59, 56, 55 and 66. The daily gains varied from 700 to 762 g. The data indicated that distillery by-products could replace soybean meal quite satisfactorily as a protein source in amino acid-fortified diets.

Setaria Sphacelata

Setaria sphacelata is a high and most prevalent tropical grass, while Cleome gynandra is a tropical annual herb which commonly used as vegetables in Africa and Asia. Both plant samples were found to be high in nutritive value especially in protein and very appetizing in ruminants. The main objectives of the study were to measure and compare the nutritional composition of Setaria sphacelata and Cleome gynandra as a function of their nutritional value for ruminants. The two plant samples were collected near the Tembila area, Besut Terengganu. The samples were dried in a furnace below 60 - 70 ˚C and crushed prior to further analysis using proximate analysis. Proximate analysis was used to measure values for moisture, dry matter (DM), ash, crude protein (CP), crude fibre (CF), ether extract (EF) and nitrogen-free extract (NFE). The result of this analysis shows that Cleome gynandra had much higher crude protein (CP) (p < 0.05) at 36.86% and ether extract (EF) at 5.50%. Crude protein (CP) is one of the most essential nutrients that ruminants need. Therefore, this study found that Cleome gynandra contains a higher nutritional value in terms of crude protein (CP) than Setaria sphacelate, which can be used as a feed for ruminants.

Two digestibility and nitrogen balance trials were conducted to evaluate the feed value of barley-derived distillers dried grains with solubles (BDDGS) and semisolid distillers solubles from barley and wheat (BDS and WDS) in rations for growing pigs. The average crude protein, lysine, crude fibre and neutral detergent fibre contents of BDDGS, BDS and WDS were, respectively: 30.6, 20.6, 30.7 %; 1.7, 1.7, 2.6 g/16 g N; 16.1, 2.0, 3.1 %; 69.4, 2.3, 7,1 %. Available lysine was greatly reduced in all samples. The distillery by-products composed 33 % of diet DM in the barley based rations. The control diet was a mixture of barley and skim milk powder. The organic matter and crude protein digestibilities of BDDGS, BDS and WDS were 40.5, 80.4, 85.0 % and 52.4, 46.9, 77.5 %, respectively. Their FU values and DCP values were 0.50, 0.94, 0.94/kg DM and 319, 102,253 g/FU. on the WDS diet, nitrogen retention, as g/d, was similar to that on the control diet, but on the diets with barley distillery products it was reduced due to the lower amount of protein absorbed, especially the lower lysine intake. Barley distillers by-products proved to have low feed values for pigs in this study, but the value for WDS was quite reasonable. The new integrated starch ethanol process can be expected to yield more suitable fractions for use in pig rations.

The metabolizable energy (ME) and partly also the digestibility of several industrial by-products, mainly originating from grain, were determined in trials with adult cockerels. Five experiments were performed using a conventional total collection procedure, and test ingredients were substituted for 25-40 % of the basal diet. The nitrogen-corrected apparent (AMEn) and true (TMEn) metabolizable energy values of distillers’ dried grains (DDG) and distillers’ dried grains with solubles (DDGS) derived from barley, wheat and rye varied from 7.85 to 11.8 and from 7.98 to 12.0 MJ/ kg DM, respectively. The highest MEn values were observed in the dehulled barley-derived products. The digestibility of crude protein (CP) was 62-83 and that of carbohydrates 25-50 %, the latter being lowest for feeds originating from whole barley grain. The results indicated that distillers’ feeds derived from dehulled grain, especially barley, are satisfactory energy sources for poultry diets. Dried barley protein (BP 1, CP 38 %), oats protein (CP 44 %) and distillers’ solids (CP 58 %) from the integrated ethanol starch process, as well as dehulled barley and oats proved to be excellent energy feeds containing AMEn 14.9, 18.6, 15.0, 14.2 and 14.6 MJ/kg DM, respectively. The TMEn values for BPI and dehulled grains were 15.3, 14.4 and 14.8 MJ/kg DM. Supplementation with enzymes did not significantly improve the ME value of dehulled barley. The AMEn values for barley protein (BP2, CP 27 %), barley bran and barley molasses obtained from the starch process, and wheat feed meal from the milling industry, were 13.3, 8.52, 13.5 and 10.6 MJ/kg DM, respectively. The lowest ME values were obtained for samples of wheat bran, dried potato pulp and malt sprouts: AMEn 6.09, 6.23 and 6.01; TMEn 6.15, 6.07 and 6.01 MJ/kg DM, respectively.

The object of this series of investigations is to secure detailed information concerning the composition, digestibility and nutritive value of pasture grass in its different stages of growth. The results which were obtained in these respects by cutting the herbage of the experimental pasture plot at weekly and at fortnightly intervals have been described in previous communications. During the season of the present experiment, the trials have been carried a stage further by the adoption of a system of cutting at 3-weekly intervals. The main findings of the 1928 investigation are recorded below:(1) Chemical composition of 3-weekly pasture cuts: The adoption of a more lenient system of cutting at 3-weekly intervals led to a slight lowering of the percentage of crude protein in the grass and a slight raising of the percentages of crude fibre and N-free extractives. On the other hand, no corresponding effect was noted in respect of the ether extract, SiO2-free ash, lime and phosphate, the percentages of these constituents being very similar in the weekly and 3-weekly pasture samples obtained in 1928. The falling off of the percentage of crude protein in the 1928 3-weekly-mown herbage, as compared with the weekly and fortnightly-mown herbage of 1925 and 1927 respectively, was not wholly the consequence of the more lenient system of cutting, but was also due in part to the protein-depressing influence of the droughty periods which were experienced in the 1928 season.
