Nitrogen utilization was studied when eight lactating cows were offered ad libitum urea-treated corn silage (15.3% crude protein) or grass silage (14.5% crude protein), plus a grain ration at 1 kg grain to 3.5 kg of 4% fat-corrected milk, in a digestion and nitrogen (N) balance trial. Analyses of the forages indicated greater acid detergent fiber content for the grass than for the corn silage: 46.8 and 35.1% on a dry matter basis, respectively. Digestibility of dry matter, energy, crude protein, true protein, acid detergent fiber, neutral detergent fiber, and N balance were significantly greater (P < 0.05) for cows fed urea–corn silage than for those fed grass silage. The nitrogen of urea–corn silage was used more efficiently for milk and tissue protein synthesis. Decreased nitrogen utilization for cows fed grass silage was associated with lower energy and higher acid detergent fiber content for grass silage than for urea–corn silage.

ABSTRACT. Experiment were conducted to evaluate fermentation characteristics (pH, NH3, VFA), On degration in sacco degration neutral detergent fiber (NDF), acid detergent fiber (ADF) and neutral detergent insoluble nitrogen (NDIN) of feed particle in the rumen. Two fistulated Friesien Holstein grade of each feeding used in this research. The ration in given similar with the sample to measured the degration in the rumen are corn stover (CST) and sugar cane top (SCT). Disappearance of the NDF, ADF, and NDIN in the rumen was calculated based on the incubation time and using an exponential negative modwl Y= a + b (1-e-ct) from Orskov and Mc Donald, (1979). Values of a,b and c fraction were used to calculate theoretical degradation DT=a+ ((b.c)/(c+Kp)) with the assumption  of flow of particle (Kp) is about 5 %/hour. The results on fermentation characteristics of feeding corn stover give ph about 6.54 ± 0.16; N-NH3 about 7.36 ± 3.10 mg/100 ml and VFA about 64.84 ± 10.82 mmol/1, whilst for feeding sugar can to give ph about 6.54 ± 0.14; NH3 about 2.62 ± 0.85 mg/100 ml and VFA about 44.13 ± 6.7 mmol/1. The microbe activity of the degration (DT) borh fed were not significantly different for NDF and ADF but for NDIN showed significantly different (P0.05) among feeds. This results show that there utilization of single feeds corn stover and sugar can top are not optimal for microbe activity, however the values degradation of fiber fraction were above 30%.

ABSTRACTThis study aimed to evaluate sago pulp fermentation method and its effect on crude fiber content, digestibility, and utilization of sago pulp as a feed raw material for Nile tilapia. Fermentation was done using three different fermenters, i.e. yeast tapai and baker’s yeast with five doses of 10 g/kg, 20 g/kg, 50 g/kg,70 g/kg,100 g/kg, respectively, and sheep rumen liquid with five doses of 100 mL/kg, 200 mL/kg, 300 mL/kg, 500 mL/kg and 1000 mL/kg. The incubation time was 0, 24, 72, and 96 hours. In the digestibility test, tilapia (25 g) was stocked at a density of 7 fish/aquarium. Three different diets were applied in quadruplicate, i.e. reference diet (100% reference diet), unfermented sago pulp (AS), and fermented sago pulp (ASF). Three different dietary treatments (in quadruplicate) containing different carbohydrate sources were tested, i.e. cassava flour as a comparion (G), unfermented sago pulp (AS), and fermented sago pulp (ASF). Fermentation of sago pulp with tapai yeast at a dose of 50 g/kg at 72 hours incubation time could reduce crude fiber by 35.76%, neutral detergent fiber (NDF) by 32.68%, and hemicellulose by 60.39%. Fermentation with yeast tapai could significantly increase sago pulp dry matter digestibility by 34% and carbohydrate digestibility by 21%, as well as increase glucose absorption. The growth experiment showed that the use of ASF diets resulted in higher specific growth rate (3.31 ± 0.12%/ day), protein retention (47.34 ± 5.23%) and fat retention (85.58 ± 5.44%) than those of AS dietary. In conclusion, fermentation of sago pulp using yeast tapai at a dose of 50 g/kg at 72 hours incubation could reduce crude fiber content and increase dry matter and carbohydrate digestibilities, so that it can be used as a source of carbohydrates in tilapia diet.

Objective: To develop three models in order to estimate the defecation rate ofwhite-tailed deer (Odocoileus virginianus) according to the season of the year,content of neutral detergent fiber (NDF), and acid detergent fiber (ADF) in feces.Design / methodology / approach: Nine captive adult deer were assigned tothree levels of dietary fiber. Fecal groups (defecation rate) were counted, forageconsumption was estimated, and feces were analyzed for NDF and ADF content. Arandomized block design was used, where the effect of the treatments was blockedby season, and a multiple regression analysis was used to define the predictionmodels of the defecation rates.Results: The rates were different for dietary fiber levels (p&lt;0.0001), and for theyear season (p = 0.0007). For spring, the defecation rate model (DR) was DR = -4.84696 - [0.02159 (NDF)] + [0.58397 (ADF)]; for summer DR = -51.0272 +[0.26868 (NDF)] + [1.61121 (ADF)]; and for winter DR = 7.82939- [0.02667 (NDF)]+ [0.17309 (ADF)].Limitations / implications: Defecation rate or fecal group counting is a useful toolto estimate deer populations. Nevertheless, the definition of an adequatedefecation rate represents a hard task, since it depends on various factors such asthe environmental conditions, and the components of the diet the deer consumes.Findings / conclusions: The defecation rate varies depending on the year seasonand the fiber content in the diet.

The study was planned to evaluate the effect of exogenous fibrolytic enzymes (EFE) supplementation for 56 days @ 240 mg/kg total mixed ration (TMR) on digestibility of dry matter and nutrients in dairy cows. Six dry non-pregnant cows were assigned in each treatment with and without EFE. The digestibility trial of seven days was conducted after 49 days of feeding. Dry matter and nutrients intake of cows was not influenced by EFE. The supplementation of EFE had improved digestibility of dry matter, organic matter, crude fiber, neutral detergent fiber, cellulose (p less than 0.01), as well as digestibility of nitrogen-free extract and acid detergent fiber, was also higher (pless than 0.05). The body weight gain of cows was higher on the supplementation of EFE in TMR. The study concluded that feeding exogenous fibrolytic enzymes (240 mg/kg) supplemented TMR improved digestibility of dry matter and nutrients, which was reflected as higher body weight gain in dry non-pregnant Gir and crossbred dairy cows.

AbstractNeutral detergent fiber (NDF) content was the critical indicator of fiber in corn stover. This study aimed to develop a prediction model to precisely measure NDF content in corn stover using near-infrared spectroscopy (NIRS) technique. Here, spectral data ranging from 400 to 2500 nm were obtained by scanning 530 samples, and Monte Carlo Cross Validation and the pretreatment were used to preprocess the original spectra. Moreover, the interval partial least square (iPLS) was employed to extract feature wavebands to reduce data computation. The PLSR model was built using two spectral regions, and it was evaluated with the coefficient of determination (R2) and root mean square error of cross validation (RMSECV) obtaining 0.97 and 0.65%, respectively. The overall results proved that the developed prediction model coupled with spectral data analysis provides a set of theoretical foundations for NIRS techniques application on measuring fiber content in corn stover.

The near-infrared spectroscopy (NIRS) combined with modified partial least squares (modified PLS) regression was used for determining the neutral detergent fiber (NDF) and the acid detergent fiber (ADF) fractions of the chickpea (Cicer arietinum L.) seed. Fifty chickpea accessions (24 desi and 26 kabuli types) and fifty recombinant inbred lines F5:6 derived from a kabuli × desi cross were evaluated for NDF and ADF, and scanned by NIRS. NDF and ADF values were regressed against different spectral transformations by modified partial least squares regression. The coefficients of determination in the cross-validation and the standard deviation from the standard error of cross-validation ratio were, for NDF, 0.91 and 3.37, and for ADF, 0.98 and 6.73, respectively, showing the high potential of NIRS to assess these components in chickpea for screening (NDF) or quality control (ADF) purposes. The spectral information provided by different chromophores existing in the chickpea seed highly correlated with the NDF and ADF composition of the seed, and, thus, those electronic transitions are highly influenced on model fitting for fiber.

Abstract Insecticides are used widely to control a variety of pests and often residues of these insecticides are left in soil which may have impact on the phosphate solubilization potentials of rhizosphere fungi. Rhizosphere soils were collected from carefully uprooted cowpea seedlings with hand trowel on 50, 70 and 90th days of germination containing the lambda-cyhalothrin and dimethoate insecticides. Fungi associated with the above samples were identified by standard microbiological techniques. Screening for phosphate solubilization potential of the isolates was done by spot inoculation on Pikovskaya agar by measuring the clear zones around the colonies supplemented with tricalcium phosphates [Ca3(PO4)2]. The phosphatase produced by the fungal species was optimized using parameters such as incubation time, pH, temperature, carbon source and nitrogen source in submerged fermentation. The isolated rhizosphere fungi were identified as Rhizopus stolonifer, Aspergillus niger, Aspergillus fumigatus, Aspergillus terreus, Trichoderma viride, Arthroderma fulvum and Fusarium oxysporum. Among the isolates, Trichoderma viride showed the best ability to solubilize phosphate with solubilization index of 2.82 with dimethoate of 12.5ml/L of water. The optimization study for the enzyme production showed that the best incubation time for phosphatase production was 72 hours by Trichoderma viride. It was observed that the optimum pH for production of phosphatase by Trichoderma viride was 6.5. This study suggests that all the isolated fungi especially Trichoderma viride can adapt to these insecticidal treatments, which make them useful as biofertilizers to increase uptake of phosphorous in plants.
