“…The signi cant difference (P<0.05) in rumen protozoan population between treatment diets was the highest increase seen in the Diet B and Diet C groups. Similar to the results of this research, concentrate and bypass fat supplementation increased protozoan population in ewes [74]. Conversely, reported by Li et al [45], showed number of total bacteria, methanogens and protozoa were decrease with the in increasing of concentrate ratio in the diet.…”

Background: The effect of Brachiaria decumbens supplemented with concentrate and bypass fat ratio 100, 70:30, 70:15:15 (w/w) on nutritional composition, in vitro rumen fermentation and microbial population in Murrah cross and Swamp buffaloes were investigated. Incubation were conducted using rumen fluid obtained from the breed of each buffalo which were fed the same based diet (100% Brachiaria decumbens). For the in vitro fermentation characteristic after 48h incubation, total gas production, pH, total volatile fatty acid (TVFA), apparent rumen degradable carbohydrate (ARDC), methane (CH4) and ammonia (NH 3) were determined. The molecular technique also was used to quantify rumen total bacteria, total protozoa, total methanogens, Fibrobacter succinogens and Ruminococcus albus.Results: The results revealed Diet C showed significantly highest in dry matter, crude fat, metabolized energy and optimum in crude protein and carbohydrate value while lower in crude fiber as compared to Diet B and Diet A (P<0.05). In both breed were showed parameters of gas production, total volatile fatty acid (TVFA) and its proportion, and total microbial population were increased parallelly with the increase of 30% concentrate levels in Diet B, while Diet C was moderate with the presence of 4% bypass fat and 26% of concentrate (P<0.05). The methane concentration as well the total methanogens population increased significantly (P<0.05) in Diet B when compared among other diets, but no significant difference was found when comparing between buffalo species. Meanwhile, pH value was slightly decreased with the dietary supplementation in both breeds, but the population of cellulolytic bacteria was not affected.Conclusions: This study showed that dietary concentrate and bypass fat supplementation had improved nutritional composition, in vitro fermentation characteristics by increasing VFA concentration, altering total microbial population, and potentially used as new diet for buffaloes in Malaysia.

“…Additionally, high TDN in the ration with calcium soap flaxseed oil supplementation was potential to increase the availability of nutrients for rumen bacterial degradation process. Bhatt et al (2013) reported that the addition of 4 % rice bran oil in the form of calcium soaps in vivo can increase (P<0.05) total VFA production, body weight gain, body weight, dry matter intake, and lower feed conversion ratio (FCR) compared to the addition of oil in non protected or control (without the addition of oil) .…”

This experiment was designed to evaluate the effects of protected vegetable oils supplementation on in vitro fermentation characteristics, rumen microbial population, and methane production in cattle. The treatments were arranged in a complete randomized block design involving 2 factors i.e. oil type (sesame, canola, and flaxseed) and protection methods (non protected, calcium soap, and microencapsulation). Variables observed were rumen pH, N-NH 3 , total and molar proportion of VFA, dry matter and organic matter digestibility, population of protozoa and total bacteria, methane production, and hydrogen balance. Data were tested using Analysis of Variance (ANOVA) and the differences among treatments means were examined by Duncan Multiple Range Test. The oil type did not affect all variables measured. The protection method using microencapsulation significantly increased N-NH 3 concentration. There was an interaction between oil type and protection method on total VFA concentration, molar proportion of VFA, and methane production. The supplementation of calcium soap-flaxseed oil significantly increased total VFA production, while the supplementation of microencapsulated flaxseed oil had the highest propionate concentration and H 2 utilization, the lowest A:P ratio, and methane production. It is concluded that microencapsulated flaxseed oil was the best treatment to optimize rumen fermentation.

“…A number of research articles[ 1 , 3 , 5 , 12 – 15 ] have emerged evaluating rice by-products as dietary sources of nutrients in sheep production systems. However, to our current knowledge, since the late 1980’s and early 1990's research of [ 6 , 7 ], there has been no other peer-reviewed published information on sheep supplementation with rice bran in Australian prime lamb production systems.…”

BackgroundThis study examined the effects of dietary supplementation with rice bran, sire breed and gender on live animal performance and carcass characteristics in Australian crossbred and purebred Merino lambs.MethodsForty-eight lambs balanced by sire breed (Dorset, White Suffolk, Merino) and gender (ewe, wether) were randomly allocated into three dietary supplementation groups (Control- 24 lambs fed wheat/barley-based pellets, Low- 12 animals fed a 50/50 ratio of wheat-based/rice bran pellets, and High- 12 lambs fed rice bran pellets). The Rice bran pellets replaced 19 % of the barley component of the feed. Animals were group-fed at the rate of 1000 g of the supplement per head per day with ad libitum access to lucerne hay as the basal diet and water. The duration of the feeding trial was 49 days with an initial 21-day adjustment period.ResultsSire breed differences were evident for initial (p < 0.0002) and final (p < 0.0016) liveweights, hot carcass (p < 0.0030) and cold carcass (p < 0.0031) weights, as well as dressing percentage (p < 0.0078), fat thickness (p < 0.0467), yield grade (p < 0.0470) and rib eye area (p < 0.0022) with purebred Merino under-performing compared to the crossbreds. Concentrate feed conversion efficiency, costs per unit of liveweight gain and over the hooks income were comparable between treatments regardless of the observed trend where the high supplementation group tended to show lower feed intake (745.8 g/day) compared to both the control (939.9 g/day) and low supplementation groups (909.6 g/day). No significant differences (p > 0.05) were observed between treatments for live animal performance, carcass characteristics, gender and their second-order interactions.ConclusionsResults indicate that Rice bran can be utilised as a cost-effective supplementary feed source in genetically divergent sheep over a 49-day feeding period without detrimental effects on overall live animal performance or carcass characteristics.
