The Effects Of Different Qualitative And Quantitative Feed Restriction Methods During Rearing On The Reproductive Performance Of Broiler Breeder Hens, Mehmet Bozkurt, Veysel Ayhan, Fi̇gen Kirkpinar

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to determine the effect of various quantitative and qualitative feed restriction methods during the growing period on the reproductive performance of broiler breeder hens. Normal and low density diets were offered to broiler breeder pullets by three different qualitative restriction methods (every day, skip-a-day, five days in a week). The trial was conducted on 864 4 to 72 week old Avian AK-34 broiler breeder hens. The qualitative and quantitative restriction methods, examined during the growing period, had no significant effect on egg production, chick weight, settable egg rate, egg yolk and egg albumen weight, egg …

In Vitro Antibacterial Activities Of Tilmicosin And Cefquinome Alone Or In Combination Against Certain Poultry Pathogens, Seyyal Ak, Oya Keleş, Tülay Bakirel

Turkish Journal of Veterinary & Animal Sciences

The antimicrobial activities of cefquinome and tilmicosin were determined in vitro against P. multocida and O. rhinotracheale of poultry origin by serial broth macrodilution. Both antibiotics exhibited good in vitro antibacterial activity against the strains tested. The minimum inhibitory concentration (MIC) for cefquinome was 1.562 µg/ml and for tilmicosin was 0.78 µg/ml for both microorganisms. To investigate the effects of a combination of cefquinome and tilmicosin, the fractional inhibitory concentration (FIC) index was determined by checkerboard assay. The antimicrobial combination was additive against P. multocida (FIC=1) and indifferent against O. rhinotracheale (FIC=2).

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.
