AbstractThis study was conducted to determine the effects of different levels of dietary tannin on gastrointestinal tract (GIT) histology and on liver and kidney masses. Five groups of Boer goats were given diets containing 0, 50, 100, 150 and 200 g/kg of tannin for 6 weeks before data collection. Differences in the histopathology of the oesophagus, reticulum, rumen, omasum, abomasum and duodenum were evaluated. Increased dietary tannin levels induced thickening and/or keratinization of epithelial tissue in the reticulum, rumen, omasum and abomasum. Increased tannin levels also resulted in a loss of epithelial cells, erosion of microvilli and shortened villi height in the duodenum, which could impair the absorption of nutrients. Consequently, condensed tannins had a negative effect on the histopathology of the Boer goats.

Nutrients Digestibility

This study was aimed at determining the possibility of applying rapeseed cake (RC) and wheat distillers dried grains with solubles (DDGS) in diets for HYPLUS meat-type rabbits (n = 64, aged 35–84 days). Control diet (SC) contained 5% of extracted soybean meal. In RC diet, the soybean meal was replaced by RC, in DG diet – by wheat DDGS, whereas in RC–DG diet – by a mixture of RC and wheat DDGS (2.5% each). The study included production analyses, digestibility-balance experiment and physiological assessment of gut response to experimental factors hence data was collected on daily bodyweight gains, feed intake and slaughter performance, nutrients digestibility, nitrogen retention and gut response. The latter included assessment of parameters describing the small intestinal, cecal, and colonic environment of rabbits (e.g. digesta viscosity, ammonia concentration, bacterial enzymes activity, short-chain fatty acid concentration). The highest productivity results were reported for SC group and the lowest ones for DG group. The RC and RC–DG groups were characterised by intermediate productivity. Dressing percentage and contents of carcass elements did not differ among the groups (except for the hind part). Nutrients digestibility and nitrogen retention were the highest in the SC group and the lowest in DG group. The dietary incorporation of DDGS resulted in undesired responses of the gastrointestinal tract including excessively watery digesta in the small intestine, increased concentration of cecal and colonic ammonia, enhanced activity of potentially harmful bacterial β-glucuronidase in cecal digesta, and increased cecal concentration of putrefactive short-chain fatty acids. These negative effects were not due to RC and RC–DG dietary treatments, apart from decreased dry matter concentration in the small intestine in the RC–DG group. In general, the results of our study demonstrated that 5% rape cake can be successfully incorporated into rabbit dietary regimen as a substitute of dietary soybean meal. Considering that the productivity of rabbits fed 2.5% of DDGS (with 2.5% rape cake) and these receiving 5% rape cake was comparable, optional seems also dietary inclusion of up to 2.5% wheat DDGS The higher content of DDGS (5%) in the diet deteriorated most of the growth parameters of rabbits.

(Improvement of fermented bagasse quality as animal feed by fermentation through administration of sago flour at different levels)ABSTRACT. Feed plays an important role in livestock production system. Due to limitation of pasture and forege areas, it needs to find new feed alternative as replacement of forage as animal feed. One of feed alternatives as replacement of forage is bagasse. Bagasse has low nutritive content and digestibility. One of the efforts to improve bagasse quality is by fermentation. The purpose of this experiment was to improve nutritive values of bagasse by fermentation method by using Trichoderma harzianum as inoculum. This research was conducted at Animal Nutrition Laboratory, Animal Husbandry Department, Agricultural Faculty, Syiah Kuala University, Banda Aceh from January to April 2015. The experiment was designed by completely randomized design (CRD) with 4 treatments (addition of sago flour at defferent levels); R1 control (0% sago flour), R2 (5% sago flour), R3 (10% sago flour), R4 (15% sago flour) of fermented material. Each treatment has 4 replications, therefore there were 16 units of treatment. Parameters observed in this experiment were nutritive values of fermented bagasse including the contents of dry matter, crude protein, crude fiber and ash. The results of the experiments indicated that fermented bagasse with Trichoderma harzianum by addition of various levels of sago flour had significantly effect (P0, 05) on crude fiber and ash contents. However, there were not significantly difference (P0, 05) on dry matter and crude protein contents. In conclusion, addition of various levels of sago flour by using Trichoderma harzianum at fermented bagasse was able to improve nutritive values of fermented bagasse.

This experiment conducted for studying the effects of crushed cinnamon and ginger to the diet at levels 0.1, 0.3, 0.6% in the bacterial growth of gastrointestinal tract of the quail. Ninety birds one day age divided randomly into ten transactions as 9 birds per treatment (three birds per duplicate). The numbers of bacteria, total aerobic bacteria in the colon of feces of birds were calculated, the results showed a significant reduction in the number of aerobic bacteria and the numbers of bacteria in the colon. Proportionally increase in the levels of crushed cinnamon, ginger, individually or in combination in comparison the control group showed influence inhibitory to the numbers of bacteria in the colon and aerobic bacteria when you add different levels of transactions compared to crushed ginger and cinnamon mixture into the bush.

Ruminant Feed

Stem and stump of bananas have potential to be used as an alternative for ruminant feed. However, one of the problem is its rapidly decomposing which affect high of water content. The alternative way to solve this matter by using silage. The aim of this study was to determine the nutritional quality of banana waste silage (stems and stump) with the addition of molasses with different levels. The experimental design was a Completely Randomized Design in factorial 3 × 3 with two replications. The first factor (A) was the composition of the substrate, A1: stump 100% + stem 0%, A2: stump 50% + stem 50%, and A3: stump 0% + stem 100%, while the second factor (B) was the levels of molasses (0; 2.5; and 5%). The parameters measured were dry matter, crude protein, crude fiber, extract ether, ash and BETN. The results showed that the composition of the substrate has significant effect (P<0.05) increased content of dry matter, crude protein, crude fiber, BETN, but did not significant (P>0.05) on extract ether and ash content. There was an interaction (P<0.05) between the substrate composition and the addition of molasses on the content of the ash. The best composition for increasing the nutrient content was stump 100% + stemps 0%. It is conclude that the compostion of stump and stemps may affect the nutrient quality of silage.

The influence of dietary crude fiber (CF), and the methods used in formulating high-fiber diets, on digestibility coefficients were investigated. Following a 10-wk adaptation period to the four dietary treatments, two barrows and two gilts per treatment, of an average initial weight of 67 kg, were transferred to metabolism crates. Diet 1 contained 14.1 MJ digestible energy (DE) per kg, 17.1% crude protein (CP) and 4.1% crude fiber (CF). Diets 2, 3 and 4 each contained 22% oat hulls, which were added to the diets isonitrogenously (diet 2), by simple dilution (diet 3), or isonitrogenously and isoenergetically (diet 4). The three diets contained, respectively, 9.8, 9.6 and 10.2% CF, 12.2, 12.5 and 14.8 MJ DE/kg and 17.0, 14.4 and 17.3% CP. Pigs fed diet 1 had significantly higher dry matter (DM) digestibility than those fed the higher fiber diets. Dry matter digestibility was also significantly influenced by the method of addition of CF with coefficients of 70.2, 72.8 and 65.0% for diets 2, 3 and 4, respectively. The inclusion of 11.5% tallow in diet 4 significantly improved ether extract digestibility over that obtained with diets 1, 2 and 3. Apparent digestibilities of nitrogen and amino acids were unaffected by the level of CF in the diet. Qualitative and quantitative changes in the energy and nitrogen level of diets with similar CF levels were associated with significant differences in the digestibility of CF, neutral detergent fiber and acid detergent fiber.
