Studies on Thyroid Hormones and some Biochemical Constituents of Follicular Fluid in Buffalo DOI: http://dx.doi.org/10.6000/1927-520X.2014.03.01.5 Published: 21March 2014 |
Abstract: Present study investigated the levels of some biochemical constituents and thyroid hormones in follicular fluid and serum and compared their concentrations in different size follicles of buffaloes. Buffalo ovaries with unknown reproductive status were collected from abattoir. The follicles visible on its surface were classified based on their diameter as small (<5 mm), medium (5-10 mm) and large (>10 mm) follicles. Twenty four samples from follicles along with blood samples of buffaloes belonging to respective category were collected. The follicular fluid and the serum samples were analyzed for total proteins, albumin, cholesterol, glucose and hormones tri-iodothyronine and thyroxine. The results of the present study revealed that, there was no specific trend observed in the levels of total proteins and albumin according to the size of the follicles but there was significant difference (P<0.01) in the levels of total proteins in follicular fluid and serum. The levels of total cholesterol showed increasing trend as the size of the follicle increases but the variations are not statistically significant. The serum total cholesterol concentration was significantly higher (P< 0.01) than that of follicular fluid. There was increasing trend of glucose concentration in the follicular fluid and also in the serum of respective buffalo with increase in the size of the follicle but the difference was non-significant. The serum glucose concentrations were significantly higher than the levels in the follicular fluid. There was no variation in the serum levels of triiodothyronine between buffalo bearing small and medium sized follicle while, highest serum level was observed in buffalo bearing large sized follicle. The significant (P≤0.01) increase in the levels of T3 in large sized follicle may attribute to the increase in the activity of monodeioniase enzyme. The follicular fluid thyroxine level showed increasing trend with the size of the follicle but the variation was not significant. There was no significant variation in the levels of T4 in serum and follicular fluid in all the groups.

Editor’s Choice : Usage of Saliva as Alternative Biological Fluid to Serum for Minerals, Energetic and Hormones Assessment in Lactating Egyptian Water Buffaloes
Usage of Saliva as Alternative Biological Fluid to Serum for Minerals, Energetic and Hormones Assessment in Lactating Egyptian Water Buffaloes DOI: http://dx.doi.org/10.6000/1927-520X.2013.02.03.1 Published: 30 November 2013 |
Abstract: Blood sample is the most common biological fluid utilized for diagnosis and monitoring of diseases. Saliva contains locally produced substances as well as serum component, so the aim of this study is to compare the profile of minerals, energetic and hormones in Egyptian water buffaloes. Blood serum and saliva samples were collected from 80 healthy multiparous, non- pregnant lactating Egyptian water buffaloes. Both fluids were tested for sodium, potassium, chloride, calcium, phosphorous, magnesium, insulin, cortisol, ACTH, glucose, urea, creatinine, total protein and immunoglobulin [IgA]. The results revealed that, serum concentrations of calcium, glucose, total protein, sodium, chloride, Insulin, cortisol, ACTH and IgA were significantly higher than saliva. In contrast, the concentrations of potassium and phosphorous in the saliva were significantly higher than that of serum. On the other hand no significant change in respect of urea, creatinine and magnesium was noted between saliva and serum. The relationships between saliva and serum of the estimated parameters were significantly positive except the concentrations of insulin in saliva and blood serum did not correlate. In conclusion, the saliva sample can be used in clinical practice with high level of reliability and provide non-invasive biological fluid for monitoring of different parameters in Egyptian water buffaloes.

Editor’s Choice : Lactation Persistency in Bulgarian Murrah Buffalo Cows
Lactation Persistency in Bulgarian Murrah Buffalo Cows DOI: http://dx.doi.org/10.6000/1927-520X.2013.02.03.3 Published: 30 November 2013 |
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%.

Editor’s Choice : Comparative Analysis of Molecular Structure, Function and Expression of Buffalo (Bubalus bubalis)
Comparative Analysis of Molecular Structure, Function and Expression of Buffalo (Bubalus bubalis) DOI: http://dx.doi.org/10.6000/1927-520X.2013.02.02.2 Published: 30 June 2013 |
Abstract: Toll-like receptor 9 (TLR9) has been characterized as a receptor that recognizes unmethylated CpG motif and triggers a pro-inflammatory cytokine response that influences both innate and adaptive immunity. Buffalo is an economically important livestock species in many Asian and Mediterranean countries, but there is little information available on its TLR9 structure and response to stimulation with its agonist CpG-ODNs. Hence in this study, we report the analysis of newly sequenced buffalo TLR9 gene fragment. In this study, buffalo TLR9 amino acid sequence revealed close association of TLR9 proteins within other bovines and small ruminants; but high divergence from other species.Multiple alignment of deduced amino acid sequence of Bubalus bubalis TLR9 with other species showed that 156/201 (74.28%) amino acids were conserved in all species. Leucine rich repeat (LRR) motifs in the ectodomain of TLR9 are responsible for molecular recognition of its agonist. The LRR pattern of Bubalus bubalis TLR9 protein was predicted towards N-terminal sequence and was found to be conserved among all species except Rattus norvegicus and Equus caballus. Blast analysis of buffalo TLR9 sequence with single nucleotide polymorphisms (SNPs) database revealed 13 SNPs out of which 7 were cds-synonymous and 6 were of the functional significance. Furthermore, kinetics of TLR9 and proinflammatory IL-1βand TNF-α cytokine expression by buffalo PBMCs influenced by CpG-ODN is also discussed.
