Abstract : Buffalo Sensory Analysis of Meat in the City of Medellin, Colombia, South America
|
|
Abstract: The aim of this study was to determine the organoleptic properties of meat buffaloes in the town of Medellin, Colombia. It was a methodology employed with satisfaction hedonic scale of five-point verbal. GLM method was employed, with the technical MANOVA, with the orthogonal contrasts canonical, determining the dimensionality, in that the response variables were expressed by the criterion of maximum likelihood. The analysis was complemented through the technique of Spearman, using the SAS statistical package version 9.0. In making, the MANOVA, for the response variables smell, taste, tact and general appearance of the product found no statistical differences (p> 0.05). However, the variables above presented statistical relationship (p <0.05), when the ANOVA analysis for each gender. The Spearman correlation coefficient showed that there are significant correlations between the different responses, for both men and women. This result indicates that the meat buffaloes, will present a good acceptance by the general public and therefore an acceptable marketing in the city of Medellin. Keywords: Meat, MANOVA, alternative food, organoleptic, spearman correlation.Download Full Article |
Abstract : Lactation Persistency in Bulgarian Murrah Buffalo Cows
|

Abstract: With the objective to establish the lactation persistency and its variability as affected by different factors, the study assigned 953 lactations of 310 Bulgarian Murrah buffalo cows bred on the farm of Agricultural Institute – Shumen within the period 1967-2009. The main method of measurement was the mean post-peak milk yield reduction. The data were processed by the conventional statistical procedure, as well as by the software products LSMLMWandMIXMDL. The persistency of milk yield after reaching peak was established to be relatively high (89.22%). Its variance is to a great extent explained by the factors days in milk (P<0.001) and parity (P<0.001), defining favorable effect of increased lactation length, and adverse effect of advancement in lactation order. The significant effect of season of calving (P<0.001) is expressed in higher lactation persistency in the autumn and winter calvers. The other environmental factor, period, and the genetic factor (individual) are significant at P<0.01, while the effect of productivity level is not. The portion of the peak yield was estimated to be 15.75% of the lactation productivity, the percentage of the greatest yield drop – 11.38%, the persistency ratio between the first and second lactation half – 73.60%.

Abstract : Metagenomic Analysis of Uterine Microbiota in Postpartum Normal and Endometritic Water Buffaloes (Bubalus bubalis)
|

Abstract: In Indian subcontinent the water buffalo (Bubalus bubalis) is one of the important livestock animals. As in cows, postpartum infection like endometritis in dairy buffaloes is major cause for the economic loss in the dairy industries. Till date, there is no study regarding metagenomic analysis of bacterial population of postpartum endometritic buffaloes. The purpose of this study was to identify and compare the uterine bacterial composition in normal and endometritic postpartum buffaloes using 16S rDNA cloning, which was a type of culture-independent methods. A total of 151 cloned plasmids for 16S rDNA from both normal and endometritic uterine samples were sequenced. Cloning library of 16S rDNA revealed clear cut difference between bacterial populations of normal and endometritic postpartum buffaloes. Cloned sequences were assigned to five major groups and one uncultured group. The five major groups include- Bacteroidetes, Firmicutes, Fusobacteria, Proteobacteria, and Tenericutes. Major cloned sequences from normal status endometrium were affiliated to phylum Proteobacteria, and most of the sequences showed high degree of similarity with bacteria Haemophilus felis. Most of the sequences from cloned library of endometritic status samples were affiliated to phylum Proteobacteria and Tenericutes. The most prevalent bacteria found in endometritic samples were Psychrobacter sp. PRwf-1, Psychrobacter pulmonis, Ureaplasma diversum strain T95 and Ureaplasma diversum strain A417. A major number of cloned sequences from both normal and endometritic samples were assigned to uncultured group. The present data showed bacterial population of postpartum normal and endometritic buffaloes and also described the presence of various types microbiota in uterine samples.

Abstract : A Comparative Study on the Physicochemical Parameters of Camel and Buffalo Milk
|
|
Abstract: This research work was carried out to compare the various physicochemical parameters of two species, camel and buffalo. Camel milk samples were collected at National Research Centre on Camel, Bikaner and buffaloes milk samples were collected from the surroundings villages of Bikaner. After collection milk samples were brought to the laboratory of NRCC Bikaner and they were analyzed for fat, SNF (Solid Not Fat), protein, lactose, total ash and pH using milk analyzer (Lactoscan). Camel milk had 2.71±0.11 fat, 6.91±0.03 SNF, 2.23±0.02 protein, 3.86±0.02 lactose, 0.79±0.004 total ash and 6.95±0.01 pH while buffalo milk had 8.71±0.82 fat, 8.44±0.19 SNF, 4.11±0.02 protein, 4.46±0.15 lactose, 0.98±0.05 total ash and 7.59±0.02 pH. Fat, SNF, protein and pH of buffalo milk was significantly (P<0.001) higher than camel milk. Lactose and total ash in buffalo milk was also higher than camel milk but at P<0.05 level. So it can be concluded that all the studied parameters were high in buffalo milk than camel milk. Keywords: Fat, SNF, Protein, Lactose and Milk Analyzer.Download Full Article |
