Carbohydrate Digestibility

Efforts to reduce protein in fish feed by maximizing the use of carbohydrates as an energy source must be supported by exogenous enzymes. One source of exogenous enzymes that can be used as a polysaccharide degrading agent easily obtained and wasted is rumen liquid in slaughterhouses (RPH). This study aims to determine the most effective carbohydrate level after being given rumen liquid as a source of exogenous enzymes in maximizing nutrient digestibility and feed efficiency in milkfish (Chanos chanos Forsskal). This study was designed using a Completely Randomized Design (CRD) which consisted of 4 treatments and three replications. Thus there were 12 experimental units. The treatments tested were feeds with various levels of carbohydrates (27.81%; 39.50%; 46.97%; and 56.75%) then given cow rumen liquid as a source of the enzyme at a dose of 80 mL/100 g of feed. Nutrient digestibility and feed efficiency data obtained were analyzed by analysis of variance (ANOVA) and continued with the W-Tuckey test. The results showed that feeding with various levels of carbohydrates in the feed that was first given cow rumen liquid waste had a significant effect (P<0.05) on fibre digestibility, carbohydrate digestibility, and feed efficiency of milkfish, but had no significant impact (P>0.05) on total digestibility, protein digestibility, and fat digestibility of milkfish. The most effective carbohydrate level in feed after being given cow rumen liquid which can optimize nutrient digestibility and feed efficiency of milkfish, is 46.97%.

Two experiments of a factorial design (sex × treatment) were conducted to determine the effects of enzyme and salinomycin supplementation on the nutritive value of barley or rye-based diets for growing pigs fed from approximately 20 to 85 kg. For exp. 1, 72 crossbred pigs were fed either a barley-based control diet or a similar diet supplemented with enzyme (Aspergillus niger; 750 units g−1 beta-glucanase and 650 units g−1 pentosanase), salinomycin (25 ppm) or both additives in combination. For exp. 2, two replicates of 48 pigs were fed either a barley-based diet, an unsupplemented rye-based diet or a rye-based diet supplemented with enzyme, salinomycin or both additives. During both experiments, chromic oxide (0.5%) was added to the diet of four to six pigs/treatment to act as a digestibility indicator starting when the pigs reached 42 kg. Neither enzyme nor salinomycin, alone or in combination, significantly improved the growth rate or feed efficiency of pigs fed barley or rye. Supplementation of barley with the combination of additives significantly (P < 0.05) improved protein digestibility while neither enzyme nor salinomycin had any effect on nutrient digestibility when fed alone. In rye-based diets, salinomycin, both alone and in combination, significantly (P < 0.05) improved the digestibility of crude protein and energy. Dry matter digestibility of the rye-based diets was unaffected by treatment. Key words: Swine, rye, barley, beta-glucanase, pentosanase, salinomycin

This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) and protein resources (soy or rapeseed meals) on gut morphology and protein digestibility of broiler chickens. Three hundred eighty-four male Ross-308 broiler chickens were used with a 23 factorial arrangement with treatments according to a completely randomized design. The morphological examinations of the intestine were carried out on 1-cm long excised segments from duodenum, jejunum and ileum. Adding wheat to the diet increased small intestine length in birds compared to other feedstuffs (P <0.05). Duodenum crypt depth and jejunum villi length were also higher in groups fed with rations containing wheat (P <0.05). Groups that received thyme essential oil and enzyme supplementation had increased length of the duodenum (P <0.05). However, the two- and three-factor interaction effects were not significant. Protein digestibility was not affected by treatment (P >0.05). Feeding wheat to broiler chickens may increase the surface area for nutrient absorption in the small intestine as compensation for the anti-nutritive activity of non-starch polysaccharides in wheat-based diets. Wheat based diets are expected to be acceptable for broilers when supplemented with appropriate enzymes or thyme essential oil.

Abstract The objective was to evaluate digestibility and sorting behaviour of grass hay processed to differing severities. Thirty-six wether lambs were used in a completely randomized design and fed diets consisting of grass hay (82.2 %), whole barley (15.7 %), and a mineral-vitamin supplement (2.1 %). Treatments included: unprocessed hay (CON); shredded hay (SHRED); chopped hay (CHOP); and ground hay (GRIND). Lambs were fed their respective diet for 20 d followed by 4 d for measurement of feed intake and fecal output. Lambs fed CON (1.23 kg and 3.24 %) had greater DMI (P = 0.04 and 0.05) compared to CHOP (1.04 kg and 2.71 % BW), with SHRED (1.17 kg and 3.11 % BW) and GRIND (1.13 kg and 2.97 % BW) being intermediate. Undigestible NDF intake tended to decrease as processing severity increased (P = 0.05). Dry matter digestibility (67.6, 66.2, 59.6, and 60.8 % for CON, SHRED, CHOP, and GRIND, respectively; P &lt; 0.01) generally decreased as the severity of forage processing increased. Crude protein digestibility was greatest in CON (68.6 %) compared to SHRED (60.83 %), CHOP (58.7 %), and GRIND (58.5 %; P &lt; 0.01). ADF and aNDFom digestibilities were greater for CON (57.4 and 67.2 %) and SHRED (60.0 and 67.9 %) compared to CHOP (44.8 and 54.6 %) and GRIND (48.3 and 58.5 %; P &lt; 0.001). CON and SHRED lambs sorted for larger particle sizes (particles &gt; 19 mm and 8 to 19 mm; P &lt; 0.001 and 0.025, respectively) while CHOP and GRIND lambs sorted for smaller particles (particles 4 to 8 mm and particles &lt; 4 mm; P &lt; 0.001 and 0.003, respectively). These results indicate that processing of grass hay does not increase nutrient digestibility partly because of the sorting behaviour of lambs.
