Abstract : Effect of Saccharomyces cerevisiae Live Cellson In Vivo Digestibility and Nitrogen Excretion in Lactating Buffaloes
|
|
Abstract: The effects of dietary inclusion of Saccharomyces cerevisiae cultureon intake, in vivo digestibility, and fecal nitrogen excretion were examined in dairy buffalo. Forty lactating buffalo cows were equally divided into Control and Saccharomycesgroups, balanced for milk production, parity, and days in milk. Two subsequent 16-d experimental phases were carried out. For both groups during the first experimental period a TMR based on maize silage (maize-TMR) was used, whereas in the second period an alfalfa haylage (alfalfa-TMR) was administered to the animals. In each experimental period, Saccharomyces group was supplemented with 50 g/head/day of yeast (Biocell®, Limena, Padova, Italy), corresponding to 20×109 CFU/head/day Saccharomyces cerevisiae NCYC Sc47 strain. The yeast supplement was top-dressed onto the morning feed. Dry matter intake (DMI) was assessed for 6 consecutive d on group basis, by the difference between feed offered and refused. In the last 3 days of experimental period in vivo digestibility was determined by using acid-insoluble ash (AIA) as an intrinsic digestibility marker. Saccharomyces supplemented buffalo cows presented greater DMI of maize-TMR, whereas no statistical differences between the groups were observed for alfalfa-TMR. Saccharomyces supplementation significantly improved in vivo digestibility of both TMR. Fecal nitrogen excretion was significantly reduced by the use of yeast supplementation. Results suggest that the inclusion of Saccharomyces cerevisiae culture in the diet for lactating buffaloes can be recommended for its effects on cow’s digestive efficiency and fecal nitrogen excretion.

Abstract : Studies on Thyroid Hormones and some Biochemical Constituents of Follicular Fluid in Buffalo
|
|
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.

Abstract : Mesopotamian Buffaloes (The Origin)

Abstract: The aim of this study to throw light on Iraqi Buffalo origin, comparing between past archeological theories based on ivory materials and cylindrical seals findings in Mesopotamia and recent molecular biological studies that based on DNA data. The highest population density found in Mesopotamian Marshlands between three southern governorates (Basrah, The-qar and Missan), respectively which represented the home tract of buffalo and their typical breeders in Iraq, locally named Ma"dan, well known by their traditional community, and characteristic accent, mainly raising buffalo for production of famous dairy thick butter cream, widely consumed by Iraqis at breakfast, named (GAYMER). There is no justification to classify Iraqi buffaloes to a distinct breed, we have many phenotypes from black, piebald to albinoid, with traditional raising system. There is no registration of cross breeding, only interbreeding, but latest country Karyotyping survey and body dimensions revealed that our buffaloes were from reverine type in most populations with large size and have good potentials for milk production. There have been numerous archeological theories around world based on cylindrical seals and archeological materials in determining the origin of buffalo in Mesopotamia and Indus Valley. Developing in molecular genetics studies will appeared to throw light on these archeological evidences, there are three recent DNA basis studies, the most updated Microsatellites markers Iraqi study [1] showed that our buffaloes were originated in Iraq, not imported from India, while the two other studies [2, 3] support the theory that Mesopotamian buffaloes were brought to Iraq from the Indian subcontinent before thousands of years and their breeders (MA''DAN) from Marsh Arabs are descendants of the population Sumerians principals from the region. According to archeological remains referring to buffalo raising in Mesopotamia before Christ confirming by recent Iraqi molecular studies, these updated data should leading us to register our buffalo as dependant breed in riverine group under the name of (Mesopotamian Buffalo) the home tract that had been raising, with achieving all tools to upgrading and protecting this old National Genetic resource all around country. We need more phylogenic studies should be achieved on Iraqi buffaloes for confirming when and where originated and domestication was happened. Still open question?

Abstract : Usage of Saliva as Alternative Biological Fluid to Serum for Minerals, Energetic and Hormones Assessment in Lactating Egyptian Water Buffaloes
|

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.
