Microbiological Analyses

The present study investigated in dogs the dietary effects of intact seaweeds on some fecal bacterial populations and metabolites, fecal IgA and apparent total tract digestibility (ATTD). Ten healthy adult dogs were enrolled in a 5 × 5 replicated Latin square design to evaluate five dietary treatments: control diet (CD); CD + Ascophyllum nodosum; CD + Undaria pinnatifida; CD + Saccharina japonica; CD + Palmaria palmata (n replicates per treatment = 10). Seaweeds were added to food at a daily dose of 15 g/kg. The CD contained silica as a digestion marker. Each feeding period lasted 28 d, with a 7 d wash-out in between. Feces were collected at days 21 and 28 of each period for chemical and microbiological analyses. Fecal samples were collected during the last five days of each period for ATTD assessment. Dogs showed good health conditions throughout the study. The fecal chemical parameters, fecal IgA and nutrient ATTD were not influenced by algal supplementation. Similarly, microbiological analyses did not reveal any effect by seaweed ingestion. In conclusion, algal supplementation at a dose of 15 g/kg of diet failed to exert noticeable effects on the canine fecal parameters evaluated in the present study.

Abstract Ancient grains are becoming an increasingly abundant carbohydrate source in the pet food market as a result of their popularity and novelty in the human market. Thus, it is imperative to evaluate the characteristics of these ingredients in vivo. Ten adult intact female beagles were used in a replicated 5x5 Latin square design. Five dietary treatments were evaluated containing either: rice (CON), amaranth (AM), white proso millet (WPM), quinoa (QU), or oat groats (OG). All diets were formulated to include 40% of the test grain and to be isonitrogenous, isocaloric, and nutritionally complete and balanced for adult dogs at maintenance. The objectives were (1) to evaluate the effects of the novel carbohydrate sources on total apparent total tract digestibility (ATTD), fecal microbiota, and fermentative end-product concentrations and (2) to evaluate the effects of novel carbohydrate sources on the post-prandial glycemic and insulinemic responses in healthy adult dogs. All diets were well-accepted by the dogs and fecal scores remained within ideal range for all treatments. In terms of ATTD, all diets were well-digested by the dogs; WPM had the highest digestibility of dry and organic matter in contrast with dogs fed the other treatments (P < 0.05). Additionally, ATTD of total dietary fiber was highest for WPM (72.6%) in contrast with QU (63.5%) and CON (50.8%) but did not differ from AM (65.7%) and OG (66.6%). Dogs fed AM or OG had greater (P < 0.05) fecal concentrations of total short-chain fatty acids, as well as propionate and butyrate concentrations, than CON. Ancient grain inclusion appears to beneficially shift fecal microbial populations, with increases in relative abundances of butyrogenic bacteria (i.e., members of the Lachnospiraceae family) observed for OG and reductions in Fusobacteriaceae for both AM and OG when compared with CON. Post-prandial glycemic and insulinemic responses did not differ among treatments. Together, these data suggest that ancient grains can be included up to 40% of the diet while eliciting beneficial effects on overall host health without detrimentally affecting nutrient digestibility.

The study examined the extent to which n-3 PUFA from different sources were biohydrogenated in the rumen and their effects on rumen microbial efficiency and whole tract nutrient digestibility. Four ruminally and duodenally cannulated wether lambs were used in a 4×4 Latin square design. Four iso-energetic and iso-nitrogenous diets based on dried grass were formulated to provide similar fat levels (60g/kg DM) from different sources; Megalac (palmitic acid: C16:0; Control), whole linseed (α-linolenic acid, C18:3n-3 ; Linseed) fish oil (eicosapentaenoic acid, C20:5n-3, EPA and docosahexaenoic acids C22:6n-3, DHA; Fish oil) and whole linseed plus fish oil providing equal amounts of oil (LinFish). Diets were offered at a rate of 1·2kg/day in 12 equal portions.Total fatty acid intake was similar on all diets whilst duodenal fatty acid flow varied between 101, 94, 87 and 90% of dietary intake for animals fed the Control, Linseed, Fish oil and Linfish diets respectively. Duodenal flow of C18:3 n-3 in animals fed the Linseed diet was twice that of animals fed the Control diet (P < 0·01) whilst animals fed the Fish oil diet had a significantly greater flow of EPA and DHA than those fed any of the other dietary treatments. Duodenal flow of trans C18:1 in animals fed the Linfish diet was significantly greater than that in animals fed either Linseed, Fish oil or Control diets (P < 0·001). Biohydrogenation of C18:3n-3 was 80 to 93% in all diets whilst that of C20:5n-3 and C22:6n-3 was 72 to 79% in diets that contained fish oil or linseed and fish oil. Apparent fatty acid digestibility (duodenum to rectum) tended to be greater for unsaturated than saturated fatty acids whilst whole tract fatty acid digestibility (mouth to rectum) was significantly greater in animals fed diets containing fish oil (P0·05). All dietary n-3 PUFA sources decreased microbial protein synthesis and efficiency when expressed as either gN/kg organic matter (OM) apparently or truly degraded in the rumen. Additionally, the inclusion of fish oil increased the proportion of propionate in the rumen whilst depressing the rumen digestibility of OM and fibre (P < 0·01), but had no significant effect on whole tract OM or fibre digestibility.

Saccharomyces cerevisiae has been used to enhance the protein level of low-protein feedstuffs such as cassava root. In the present study, fresh cassava root was grated and subjected to solid-state fermentation with S. cerevisiae to enhance the protein content. The fermentation process lasted for 21 days, followed by fermentation with yeast for 5 days. The fermented product was called yeast-fermented cassava root (YEFECAR). The YEFECAR was then evaluated as a feed ingredient at 10%, 20% and 30% dry matter in concentrate diet for dry matter intake and nutrient digestibility in non-pregnant female Brahman beef cattle (bodyweight 256 ± 11.5 kg). Four cattle were randomly given four treatments in 4 × 4 Latin square design for 21-day period, including a control diet (without fermented cassava root). Cattle were fed rice straw as roughage. The results showed that while dry matter intake was not significantly different among dietary treatments, average dairy gain tended to increase when fermented cassava root was fed at 20% in the concentrate diet. There were no significant differences in nutrient digestibility among the dietary treatments. However, neutral detergent fibre and acid detergent fibre digestibility showed an increasing trend when fermented cassava root was fed to the cattle. Likewise, fermented cassava root showed no effect on rumen microbial population, although rumen bacterial population and microbial protein tended to increase with YEFECAR addition. It was concluded that yeast-fermented cassava root at 20% in concentrate feed tended to enhance rumen bacteria population and neutral detergent fibre digestibility in cattle.

The purpose of this study was to evaluate the effects of dietary supplementation of Quillaja saponin (QS) on growth performance, nutrient digestibility, fecal microbiota, and fecal gas emission in growing pigs. A total of 50 crossbred growing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 23.83 ± 1.95 kg were randomly assigned to 1 of 2 treatments for a 56-day trial with 5 replicate pens per treatment and 5 pigs (2 barrows and 3 gilts) per pen. Dietary treatments including control diet and control diet supplemented with 200 mg/kg QS. The average daily gain was significantly increased during days 0-56, while the fecal ammonia emission on day 56 and fecal coliform bacteria counts on day 28 were significantly decreased in pigs fed with QS containing diet. However, dietary supplementation of QS had no significant effects on apparent total tract digestibility. In conclusion, dietary supplementation of 200 mg/kg QS had beneficial effects on growth performance, fecal microbiota, and fecal gas emission in growing pigs. Considering the carry-over effects, the adaption period should be at least 28 days when supplementing 200 mg/kg QS to the diet of growing pigs for improving the growth performance.

High Forage

Abstract Supplementation of ruminant diets with the investigational methane (CH4) inhibitor 3-nitrooxypropanol (3-NOP; DSM Nutritional Products, Switzerland) is as a promising mitigation strategy. However, most studies have examined high grain or mixed forage-concentrate diets. The objective of this study was to evaluate the effects of supplementing a forage diet with 3-NOP on rumen fermentation, CH4 emissions and apparent total-tract nutrient digestibility. Eight ruminally cannulated beef heifers (BW = 514 kg) were randomly allocated to two treatments in a crossover design with 49-d periods. Dietary treatments were: control, high-forage diet (90% forage DM basis) without 3-NOP; and NOP, control diet supplemented with 150 mg 3-NOP/kg DM. After a 14-d diet adaption, dry matter (DM) intake (DMI) was recorded daily. Rumen contents were collected on days 17 and 28 for volatile fatty acid (VFA) analysis, whereas ruminal pH was continuously monitored from day 20 to 27. Diet digestibility was measured on day 38 to 41 by total collection of feces. Enteric CH4 emissions were measured on days 46 to 49 in chambers. Dry matter intake was lower (P = 0.001) for NOP (10.0 kg/d) as compared with control (10.2 kg/d). However, DM, neutral and acid detergent fiber, and crude protein digestibilities were similar between treatments (P ≥ 0.29). Although total VFA concentration was not affected by treatment (P = 0.19), the reduction in acetate and increase in propionate proportion for NOP lowered (P &lt; 0.001) the acetate to propionate ratio by 18% as compared with control. Mean pH was lower (P = 0.03) for control (6.46) than NOP (6.57). Furthermore, CH4 yield (g/kg DMI) was 21.6% less (P &lt; 0.001) for NOP relative to control (25.5 g/kg DMI). Overall, the results indicate that enteric CH4 emissions were effectively decreased with 3-NOP supplementation of a forage diet without affecting apparent total-tract digestibility of nutrients.

This study was conducted to investigate the effect of vegetable oil and yeast fermented cassava pulp (YFCP) supplementation on feed intake, nutrient digestibility and rumen fermentation in Thai Friesian dairy cows (Thai native x Holstein Friesian). Eight Thai Friesian dairy cows (447±44 kg.BW) were assigned to 4×4 double latin square design (DLSD) with two sources of oil i.e. palm oil (PO) or soybean oil (SBO) and four levels of YFCP (0, 5, 10 and 20%DM) in the dietary treatments. All cows received total mixed ration (TMR) comprised of rice straw to concentrate at a ratio of 40:60. The results showed that supplementation of SBO had lowered feed intake, nutrients digestibility, metabolize energy intake (MEI), total digestible nutrient (TDN) and methane emission than PO treatment. However, cows received SBO had greater total volatile fatty acid (TVFA), propionic acid (C3), butyric acid (C4) than cows received on PO (P less than 0.05). In addition, supplementation of YFCP at 10%DM in the diet as an optimum level in dairy cow diets (P greater than 0.05). Finally, the interaction between the addition of SBO and YFCP at 10%DM (SBO+YFCP) had a positive effect on enhancing ether extract intake (EEI) in dairy cows.

This experiment was conducted to investigate the effect of palm oil and sunflower oil supplementations on digestibility and blood metabolites in crossbred Thai native x brahman bulls fed on TMR used rice straw as a roughage source. Four, 2 year old crossbred Thai native x Brahman bulls were randomly assigned in a 2x2 factorial in 4 x 4 latin square design. Each period of feeding lasted for 21 days to receive four dietary treatments; 3% palm oil, 6% palm oil, 3% sunflower oil and 6% sunflower oil. All animals were fed with TMR ad-libitum. It was found that supplementation of palm oil and sunflower oil had no effect on digestibility of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF) and crude protein (CP). Supplementation resulted in significant (P<0.05) lower acid detergent fiber (ADF) digestibility when feeding with palm oil on the other hand feeding beef cattle with 6% from palm oil and sunflower oil were higher Ether extract (EE) digestibility than 3% from twice oils (P<0.05). Blood glucose, blood urea nitrogen, cholesterol, triglyceride, high density lipoprotein and low density lipoprotein were not significant different among treatments. Based on this study, supplementing TMR sunflower oil in diets was suitable in beef cattle without any effect ruminal digestibility and blood metabolites.

Sweet Potato Vine

The study was carried out to determine the feed value of replacing maize with graded levels of sweet potato vine – cassava composite meal (SPV-CCM) to rabbits. Five treatment diets were formulated to contain SPV-CCM inclusion levels of 0% (control), 25%, 50%, 75% and 100%. Thirty weaned rabbits of mixed breeds and sexes were used for the experiment. They were randomly allocated to five dietary treatments with one rabbit as a replicate in a completely randomized design. Feed and water were provided ad libitum. Parameters measured were that of growth, digestibility, carcass and economics of production. The result showed that there was no significant (P>0.05) difference effect on final weight, total weight gain, daily weight gain and feed conversion ratio across the dietary treatments. There was no significant (P>0.05) difference on crude protein digestibility, crude fibre and ether extract which were within the required values for rabbit. There was no significant (P>0.05) difference on live weight at slaughter, dressing percentage, heart, liver, kidney, lungs/trachea, esophagus, stomach, small intestine, caecum, large intestine and visceral fat, there was however, a significant (P<0.05) difference in dressed weight, pancreases, spleen and kidney fat. A high cost of feeding, cost per kilogram diet and production was recorded in T and low cost of feeding, cost per kilogram diet and production in T . The result showed that 1 5 maize could be replaced by SPV-CCM up to 100% without any adverse effect on their performance, nutrient digestibility and carcass characteristics. However, the optimum performance was observed when 75% SPV-CCM replaced maize in the diet. Replacement of maize with SPV-CCM has relative cost advantage over the control diet and so should be incorporated in the diet of rabbit up to the level considered in this study.

A study was conducted for eight weeks to determine the effects of raw and cooked mucuna seed meal (MSM) based diets on the performance and haematological characteristics of cross-bred weaned rabbits. Three experimental diets were formulated to contain: 0% MSM (control diet A), X raw MSM (diet B) and 20% cooked MSM (diet C). Twelve cross-bred weaned rabbits with mean initial live-weight of about 550 g were randomly assigned to three dietary treatments. The experimental design was completely randomized arrangement. The feed intakes (115.12, 114.44, 116.15g/day) and weight gains (17.19, 12.72, 14.28g/day) for diets A, B and C respectively were similar (P>0.05) for the three treatments. Rabbits fed the control diet A had the best (P<0.05) feed conversion ratio (6.68). The packed cell volume (PCV), haemoglobin (HB), red blood cell (RBC) and white blood cell (WBC) values obtained for the three treatments were not statistically different (P>0.05) from one another. The HB, RBC, WBC values of rabbits fed on 20% cooked MSM based diet had comparable values to those on the control diet. Based on the weight gain and the haematology, 20% cooked mucuna seed meal can be included in the diet of weaned rabbits.

Twenty growing pigs with an average initial weight of 53±0.5 kg (± SE) were randomly assigned to five dietary treatments in a completely randomized design with four replicates per treatment and one animal in each replicate. A total tract digestibility trial was carried out to determine the effect of partial replacement of maize with graded levels of high quality cassava peel (HQCP) mashon the nutrient digestibility and fibre fraction digestibility of growing pigs. The control diet T1 had 40% of maize, while the dietary treatments T2, T3, T4 and T5 had7.5, 15, 22.5 and 30% of HQCP corresponding to replacement of maize by 0, 19, 38, 56 and 75% respectively. There was no significant difference (P>0.05) in apparent nutrient digestibility coefficient of dry matter, nitrogen free extract, organic matter and energy. There were significant(P<0.05)variationsintheapparentdigestibilityofcrudeprotein,crudefibreand ether extract and the crude protein digestibility decreased as the level of HQCP increased from 7.5 to 30%. Also, there was a significant (P<0.05) increase in acid detergent fibre and acid detergent lignin digestibilities with the inclusion of HQCP compared to the control, whereas there was no significant (P>0.05) influence of HQCP inclusion on hemicellulose digestibility among the treatments. It can thus be concluded that the nutritional potential of high quality cassava peel can still be realised when fed up to 30% in growing pig diet
