AbstractThe present study was undertaken to determine the Heal and total tract apparent digestibility and hindgut disappearance of dietary components and energy in a barley-based diet which included either lucerne or white-clover meal (proportionately 0·10 and 0·20). The experiment was conducted as a 5 × 5 change-over design with growing pigs fitted with simple t-shaped cannulas posterior to the ileo-caecal valve. The Heal and total tract apparent digestibilities of organic matter (OM), crude protein, crude fat, nitrogen-free extractives and energy were significantly reduced ivith increasing inclusion of lucerne and white-clover meal in the diet (P < 0·05). The total tract apparent digestibility of total fibre (TF) was significantly reduced with lucerne meal inclusion (P < 0·05), while the Heal apparent digestibility of TF was unaffected by lucerne and white-clover meal inclusion. Hindgut apparent digestibility (proportion of total tract apparent digestibility) of OM and energy was approximately 0·10, 0·70 and 0·70 for barley, lucerne and white-clover meal, respectively.Both the Heal and total tract apparent digestibility of OM and energy were significantly higher for the control diet compared with lucerne and white-clover meal (P < 0·05). There was also a significantly higher apparent digestibility of OM, TF, crude fibre and energy in the total tract for white-clover meal compared with lucerne meal (P < 0·05). For neutral- and acid-detergent fibre a similar pattern was observed, however the effect was not significant.The dietary digestible energy content was significantly reduced (F < 0·05), both at the ileum and over the total tract, with increasing inclusion offorage meal.

AbstractGrowing pigs fitted with simple t-shaped cannulas posterior to the ileal-caecal valve were used in a change-over design experiment (5 × 5) to determine the Heal and total tract apparent digestibility and hindgut disappearance of dietary components and energy in a barley-based diet with increasing inclusion of either red-clover or perennial ryegrass meal (proportionately 0·10 and 0·20). The total tract and Heal apparent digestibilities of organic matter (OM), crude protein (CP), nitrogen-free extractives (NFE) and energy were significantly reduced with increasing inclusion of red-clover and perennial ryegrass meal in the diet (P < 0·05). For all fibrous components (total fibre (TF), neutral-detergent fibre (NDF), acid-detergent fibre (ADF) and crude fibre (CF)), the ileal apparent digestibility was unaffected by level offibre inclusion in the diet. Also the total tract apparent digestibility of TF, NDF and CF were unaffected by red-clover meal inclusion, while in contrast the total tract apparent digestibility of TF, NDF and CF were significantly reduced with perennial ryegrass meal inclusion (P < 0·05). The hindgut disappearance of crude fat, NDF, ADF and CF was not affected by forage meal inclusion, whereas the hindgut disappearance of OM, NFE, TF and energy were significantly lower in the perennial ryegrass meal diets than in both the control diet and the red-clover meal diets (P < 0·05).The total tract apparent digestibility of OM was higher for the control diet compared with the red-clover and perennial ryegrass meal diets. There was also a significantly higher apparent digestibility of OM in the total tract for red-clover meal compared with perennial ryegrass meal (P < 0·05). The Heal apparent digestibility of energy in a barley-based diet with forage meal inclusion decreased proportionately by about 0·014, 0·023 and 0·030 units per unit increase ofTF, NDF and CF in dry matter, respectively. Correspondingly, for the total tract energy apparent digestibility, there was a decrease proportionately by about 0·010, 0·016 and 0·022 units per unit increase of TF, NDF and CF in dry matter, respectively. Digestible energy content was significantly reduced, as measured at the ileum or over the total tract, with increasing inclusion offorage meal (P < 0·05).

This study focuses on the determination of apparent digestibility of pasture vegetation nutrients in horses of the Old Kladruber breed through a balance indicator method (determination of acid insoluble ash). When evaluating the nitrogenous substances, their determination was based on the content of pure protein (sum of amino acids) which is more accurate than crude protein. There were differences in the chemical composition of dry matter from pasture vegetation and horse excrements. Regarding crude fat, crude fibre, acid detergent fibre, neutral detergent fibre, acid detergent lignin, ash, P and Mg, the average values in dry matter of horse excrements were significantly (P≤ 0.01) higher; on the contrary, we found significantly (P≤ 0.01) lower mean values of nitrogen-free extract, organic matter and Ca ​​in the dry mass of pasture grass. The highest coefficient of apparent digestibility for organic nutrients was determined in the nitrogen-free extract (73%) followed with organic matter (71%), pure protein (68%), crude protein (65%) and crude fat (61%). In case of fibre and its fractions, the apparent digestibility coefficients decreased as follows: crude fibre (66%), neutral detergent fibre (66%), acid detergent fibre (63%) and acid detergent lignin (42%). Significantly lower values were determined for coefficients of apparent digestibility for minerals P (16%) and Mg (50%), which highlights the need for their regular supplementation in horses on pasture. This study extends the current state of knowledge regarding the apparent digestibility of pasture vegetation which is a prerequisite for optimal nutrition of horses.

AbstractIn a factorial design, animal fat was added incrementally (0, 35, 70 and 105 g/kg) to maize starch (M) or to two sources of fermentable carbohydrates (260 g purified cellulose (C) per kg or 270 g soya-bean hulls (S) per kg). The 12 experimental diets were formulated by replacing maize starch in the control diet with fat, cellulose and soya-bean hulls of equivalent estimated net energy. Ninety-six castrated males were given these diets according to net energy. Apparent digestibilities of crude protein, crude lipid, crude fibre and nitrogen-free extract were measured and were compared with those expected from the separate ingredients. Net energy conversion ratio (nECR) was also measured. Results showed that in the C and the S diets prediction of the apparent digestibility of nutrients was worse than in the M diets (significant effect of source of carbohydrate). Prediction of apparent digestibility of crude protein and crude lipid improved as the added fat increased (significant effect of amount of fat), except in the C and S diets where for digestible crude lipid the 70 g added fat per kg gave the worst prediction (significant effect of the interaction). The net energy calculated from the experimental data on apparent digestibility was proportionately between 0·83 and 0·98 of that calculated from the expected data. The pigs on the C and S treatments showed a significant lower nECR when calculated from the expected apparent digestibility coefficients, but not when calculated from those which were measured. At the highest fat addition, the nECR was poorest. It is concluded that the amounts of digestible components in compound foods cannot always be obtained from those in the separate ingredients.

ABSTRACTThe effects of feeding monensin and amicloral at 33 and 1500 mg/kg of diet, respectively, were investigated in two experiments using 330-kg steers. Monensin and amicloral, either alone or in combination, increased the digestibility of organic matter and crude fibre compared with a control diet (P< 0·001). Crude protein digestibility was increased by monensin (P< 0·001). Use of monensin and amicloral, alone or in combination, increased molar proportions of propionic acid by 22% on average (P> 0·05), and monensin decreased butyric acid by 37% (P< 0·05).Ruminal ammonia concentrations were lower in steers fed monensin (P< 0·05). Steers fed monensin consumed 6 % less feed, gained 9 % more weight (P< 0·05) and utilized feed 14% more efficiently (P< 0·05) than control animals. Amicloral, either alone or with monensin, lowered feed intake by 11 % (P< 0·05), had no effect on average daily gain and improved feed efficiency by about 12% (P< 0·05). There were no treatment effects on any of the carcass parameters.

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.

Sixteen crossbred growing pigs Duroc x Landrace, (10 weeks of age; initial body weight 27 ± 3.92 kg) were allotted into four treatments in a randomized block design to evaluate the effects of inclusion of fermented kepok banana corm (FKBC) in the diet on the nutrient digestibility of growing pigs. There were four treatments diets offered:  basal diets without FKBC (RO); basal diets + 7% FKCB (R1); basal diets + 14% FKCB (R2); basal diets + 21% FKCB (R3). Inclusion of 21% FKBC in the diet of pigs significantly reduced (P <0.01) dry matter intake and organic matter compared to the control diet. There were no significant different between 14% and 21% FKCB on the intake and digestibility of dry matter and organic matter of the pigs. However, inclusion of FKCB at the level of 7% showed the optimum digestibility of dry matter, organic matter, crude protein, and energy with the average value of 66.57%, 70.48%, 83,43% and 70,76%, respectively. In addition, mineral consumption and retention of Ca and P were 14.3 and 9.1 g/h, respectively with the value of mineral retention both Ca and P were 11.9 and 7.5 g/h, respectively. It can be concluded that inclusion of FKCB at the level of 7% increased dry matter digestibility and organic matter.

ABSTRACTMicronization followed by grinding of brown-seeded sorghum increased starch availability in vitro but had no effect on proximate composition of the grain. In diets containing 70% of sorghum in ground or micronized and ground form, apparent digestibility of dry matter and nitrogen and nitrogen retention by growing pigs were improved (2·5, 5·0 and 12·2% respectively). Addition to the diet of 0*2 g polyethylene glycol per g crude protein in the sorghum fraction produced similar effects. In the ground cereal diet inclusion of polyethylene glycol increased apparent digestibility of gross energy (3·8%) and improved metabolizable energy content by 5·5%, but i n the micronized and ground cereal diet the additive had no effect.

AbstractGrowing pigs fitted with post-valve T-caecum cannulas were used in a change-over design experiment (5 ✕ 5) to determine the ileal and total tract apparent digestibility and hindgut disappearance of dietary components and energy in a cassava root and soya-bean meal-based diet with an inclusion rate at 0·15 of the dry matter (DM) of either cassava leaf meal, ensiled cassava leaves, groundnut foliage, or leucaena leaves.The ileal and total tract apparent digestibilities of organic matter (OM), crude protein, nitrogen-free extractives and energy of the diets were significantly reduced with inclusion of the foliages (P < 0·05). The digestibility of neutral-detergent fibre (NDF) and crude fibre was improved when groundnut foliage was included in the diet (P < 0·05).The dietary content of NDF was a better predictor of the total tract digestibility of OM (R2 = 0·87) and energy (R2 = 0·90) than the content of crude fibre (R2 = 0·68 for OM digestibility and R2 = 0·72 for energy digestibility).The disappearance of OM and energy in the hindgut of the foliage diets was 0·36 (s.d. 0·02) and 0·31 (s.d. 0·02), respectively, which was significantly lower (P < 0·05) than on the control diet (0·48 and 0·46, respectively).Ileal as well as total tract digestibilities of OM in groundnut foliage were higher than for the other leaf products (ileal, 0·55 and 0·42; and total tract, 0·64 and 0·55, respectively). For foliage products of cassava and leucaena an average digestible energy value of 11·4 MJ/kg DM was calculated, whereas for groundnut foliage the corresponding value was 10·9 MJ/kg DM.It was concluded that, inclusion of foliages in pig diets will reduce the dietary energy content, due to a high fibre content. However, under tropical conditions foliage at low levels of inclusion may be useful in low fibre diets for growing pigs to improve the dietary protein supply.
