    Effect of calcium propionate administration in first week postpartum of dairy cows on subclinical ketosi
    (Uludağ Üniversitesi, 2010-09-28) Kara, Çağdaş; Orman, Abdülkadir; Gençoğlu, Hıdır; Yavuz, Melih; Uludağ Üniversitesi/Veteriner Fakültesi.
    This study was conducted to evaluate the effect of calcium propionate administrations on serum ßhydroxybutyrate (BHBA) concentration and subclinical ketosis occurrence in dairy cows. Twenty four multiparous Holstein cows were sorted by parity, body condition score and dry matter intake in close-up period, average milk production of previous lactation and season of calving and assigned to one of the three groups. Each group consisted of eight cows. The cows in group 1 (G1) received two drenches at calving and 24h after calving. The cows in group 2 (G2) received three drenches at calving, 24h after calving and 7 days after calving. The cows in group 3 (G3) were the control (no drench). Each drench contained 0.68kg of calcium propionate. There were no statistical differences for serum BHBA concentrations at all times among groups (P>0.05), except for the difference at calving between G1 and G3 (P<0.05). Two drenches of calcium propionate tended to decrease serum BHBA concentration and the incidence of subclinical ketosis during first 4 weeks of lactation.

    Use of fructans in dogs
    (Uludağ Üniversitesi, 2011-01-19) Kara, Çağdaş; Uludağ Üniversitesi/Veteriner Fakültesi.
    Fructans are classified as prebiotic, which is defined as nondigestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, and thus improve host health. In addition to their intestinal health benefits by increasing beneficial microbial populations, fructans have been shown to decrease fecal odor components, reduce blood cholesterol, prevent or inhibit the occurrence of some types of cancer, enhance vitamin synthesis, increase mineral absorption, and stimulate the immune system. Different forms of fructans can have different physiological effects in dogs. Specific effects may vary due to fructan chain length and/or rate of fermentation. The type of diet utilized (plant-based or animal-based and level of crude protein) and variation among individual animals might greatly affect the efficacy of fructans supplementation. The full beneficial effects of fructans probably will not be experienced unless dietary concentrations are above 0.4% of dry food. In this review, the importance and effects of fructans were emphasized and the studies investigating use of fructans in dogs were summarized.
