A field study was conducted in 6 cross bred dairy cows suffering from acute clinical mastitis preceded by FMD in all animals. After thorough clinical and laboratory examination of the affected animals were confirmed as the cases of clinical mastitis. Cows were diagnosed for mastitis by clinical examination and Modified California mastitis test, somatic cell count and cultural examination of milk. After confirmation of disease and antibiotic sensitivity test all cows were subjected to precise and supportive therapy. Out of 18 quarters only 2 quarters were positive to + and one quarter to trace reaction by MCMT after the completion of treatment (on 5th day) with enrofloxacin and melonex along with supportive therapy. Out of 18 quarters only 3 quarters showed 2.5xl05 cells mL_1 to 3.25xl05 somatic cells mL_1 of milk and remaining quarters showed <2.1xl05 somatic cells mL_1 of milk. It is concluded that the result of enrofloxacin and mammitel are considerable in the treatment of clinical mastitis. © 2010 Academic Journals Inc. Source

Chhattisgarh is one of the major rice growing states of India, and paddy is the main crop, cultivated in about 76 % of area under agriculture. Mechanical weed control helps reduce the drudgery involved in manual hoeing. Manufacturing process of paddy weeder involves several operations that are to be performed sequentially, repeatedly, effectively, and hence, emphasis is to perform all the operations more efficiently as well. Jigs were designed with the help of software Solid Works and were then developed at the Faculty of Agricultural Engineering, Raipur. The saving in cost of weeding was 60 %, and saving in time was 65 % compared to manual weeding. The improved jigs facilitated the production in 60 % of time taken by traditional jigs. Taguchi method was used to solve the problems related to improving the yield and productivity. Taguchi’s design of experiments (DOE) helped pin-point the source of yield and increase the yielding efficiency. The DOE based on L8-orthogonal array of Taguchi methodology were implemented. The paper outlines Taguchi methodology to optimize the control factors having high and low settings in the production of paddy weeder. The analysis of the results showed that the optimal combination for minimum time consumption in production process is maximum number of bending with minimum welding operation and minimum number of drilling operations. The optimized process by implementation of Taguchi methodology showed a reduction of 30 % in average production time. © 2016 The International Society of Paddy and Water Environment Engineering and Springer Japan Source


A highly precise molecular marker technique, Amplified Fragment Length Polymorphism (AFLP) was used to characterize the changes in genomic structure occurred due to introduction of foreign gene and/ or due to the induced tissue culture stress during the development of various transgenic Bt rice populations. The transgenic rice plants having complex to simple Bt gene and selectable marker gene organizations were selected from the six insect resistant Bt rice lines. Our results clearly demonstrate that integration pattern, extent of rearrangement of foreign DNA and method of transformation may influence the genomic changes in transgenic rice populations. Eleven of fourteen AFLP primer combinations tested, generated distinct scorable banding pattern, which were further used in this study. Three primer combinations E-TA / M-CTT (IRRI-NPT), E-AG / M-CAC (Tulasi) and E-AA / M-CAG (IR 68899B) produced only monomorphic bands in all the transgenic and control rice plants .A percentage of 0.61% of 430 million bases of haploid rice genome were examined by the use of 11 AFLP primer combinations employed in this study. The DNA fingerprints generated by AFLP analysis, of each Bt rice population was compared with their respective non-transgenic control and was found to be > 97% similar. This indicated that the introduction of Bt gene into the genome of six rice varieties showed few genomic changes. The comparison shows that fewer changes were observed among the transgenic plants developed by Agrobacterium infection than that of developed through particle bombardment. Transgene integration pattern and their copy number were associated with the extent of genomic changes observed in the transgenic Bt rice varieties. AFLP fingerprints of the six transgenic rice varieties evidenced few, but consistent polymorphic bands between the transgenic individuals with different PI values. Relationships among the transgenic populations with their control rice plants were expressed in the form of dendrograms. Source

Arthropods living on plants are able to digest plant biomass with the help of microbial flora in their guts. This study considered three arthropods from different niches-termites, pill-bugs and yellow stem-borers-and screened their guts for cellulase producing microbes. Among 42 unique cellulase-producing strains, 50% belonged to Bacillaceae, 26% belonged to Enterobacteriaceae, 17% belonged to Microbacteriaceae, 5% belonged to Paenibacillaceae and 2% belonged to Promicromonosporaceae. The distribution of microbial families in the three arthropod guts reflected differences in their food consumption habits. Most of the carboxymethylcellulase positive strains also hydrolysed other amorphous substrates such as xylan, locust bean gum and β-D-glucan. Two strains, A11 and A21, demonstrated significant activity towards Avicel and p-nitrophenyl-β-D-cellobiose, indicating that they express cellobiohydrolase. These results provide insight into the co-existence of symbionts in the guts of arthropods and their possible exploitation for the production of fuels and chemicals derived from plant biomass.

The study was conducted in a nine-year old Ceiba pentandra (L) Gaertn. stands planted in a three tree spacing 4 × 4 m, 4 x 6 m and 4 × 8 m and two pruning regimes. Litterfall samples were collected from the field of C. pentandra for 12 months. The litterfall occurred throughout the year showing significant differences between tree spacing, pruning regimes and months. Total litterfall includes tree components (leaf litter + wood litter + flower litter + pod litter) ranged from 0.451 to 1.153 Mg ha-1 throughout the year. Total litterfall followed unimodal pattern with highest peak in April and lowest in August. In different tree spacings, total monthly litterfall, leaf litter contributed from 59 to 60%, wood litter from 30 to 31.6%, flower litter from 2.4 to 3.0% and pod litter from 6.2 to 6.8%. Litterfall was-: significantly higher in 4 × 4 m and lower in 4 × 8 m tree spacing. The study showed that litterfall was strongly and positively correlated with temperature and negatively correlated with relative humidity. The C. pentandra stands with high density returned highest amount of C and nutrients to soil. Source
