Transferrin Polymorphism In Hair Goat Breeds Raised In The Bursa Region, Cengi̇z Elmaci, Mehmet Koyuncu, Erdoğan Tuncel Jan 2001

Transferrin Polymorphism In Hair Goat Breeds Raised In The Bursa Region, Cengi̇z Elmaci, Mehmet Koyuncu, Erdoğan Tuncel

Turkish Journal of Veterinary & Animal Sciences

In this study transferrin polymorphism was investigated in hair goat breeds raised in the Bursa region by using 148 blood samples of hair goat. The separation of transferrin types was carried out using horizontal starch-gel electrophoresis. The frequencies of transferrin alleles were calculated to be 0.54 ±0.029 and 0.46 ±0.029 for Tf A and Tf B , respectively. Differences between the expected and observed number of transferrin genotypes were insignificant.

Effects Of Some Dietary Factors On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell Jan 2001

Effects Of Some Dietary Factors On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell

Turkish Journal of Veterinary & Animal Sciences

The effects of some dietary factors, other than source and amount of N and carbohydrate, on the amount and efficiency of microbial protein synthesis are discussed in this review. Specifically, these factors include dry matter intake of animals, forage:concentrate ratio of diets, rate of N and carbohydrate degradation, synchronized release of N and energy from diets, rate of passage, and other factors, such as vitamins and minerals. It seemed that diets containing a mixture of forages and concentrates increase the efficiency of microbial protein synthesis because of an improved rumen environment for the growth of more diverse bacteria species.

A Study On Cellulolytic And Hemicellulolytic Enzymes Of Anaerobic Rumen Bacterium Ruminococcus Flavefaciens Strain 17, Mehmet Sai̇t Eki̇nci̇, Numan Özcan, Emi̇n Özköse, Harry J. Flint

Turkish Journal of Veterinary & Animal Sciences

Polysaccharide-degrading enzymes of the anaerobic rumen bacterium Ruminococcus flavefaciens strain 17 were exmined. This work demonstrated that R. flavefaciens strain 17 produces a complex array of enzymes active against cellulose, hemicellulose (xylan) and lignin. These enzymes are xylanase, avicellase, acid-swollen cellulase, carboxymethyl cellulase (CMCase), pNP-cellobiosidase (pNPC), pNP-glucopyranosidase (pNPG), pNP-xylopyranosidase (pNPX) and pNP-arabinofuranosidase (pNPA). Although R. flavefaciens is an anaerobic bacterium, its enzymes worked optimally under aerobic conditions and with dithiothreitol (DTT), except in the case of pNP-xylopyranosidase. pNP-xylopyranosidase exhibited a higher level of activity under anaerobic conditions with DTT. It was demonstrated that the cross-links between arabinose side chains, which …

Turkish Journal of Veterinary & Animal Sciences

This experiment was designed to determine the effects of CZB medium on in vitro culture of murine embryos obtained from FVB/N, CD-1, and CB6F1 strains. Pronuclear stage embryos were recovered from superovulated and mated females 17 h post-hCG. Two-cell stage block, morula and blastocyst stages were used as the end point of the experiments. There is no statistical difference among strains and media for the development to the two-cell stage. However, more FVB/N embryos (88.3 and 82.4%) than CD-1 (57.4 and 57.1%) and CB6F1 (69.8 and 28.9%) reached the 3-8 cell stage in CZB and M16 media, respectively. CB6F1 embryos …
