    Comparison of growth and developmental stability traits of Japanese quails reared in conventional and enriched cages
    (Ankara Üniversitesi Veteriner Fakültesi, 2022) Narinç, Doğan; Other; Other
    This study was carried out to determine the effects of different rearing systems on some performance and welfare characteristics in Japanese quail. For this purpose, a total of 630 birds were housed in battery-type conventional cages, conventional floor cages and enriched floor cages. There were statistically significant differences between the experimental groups and the sexes in terms of the average body weight of the quails at 42 and 56 days of age (both P<0.01). Accordingly, it was determined that the average body weight of the quails raised in the conventional battery cages were higher than those raised both in the conventional and enriched floor cages. Gompertz growth curve model parameters of β0, β1, β2 were estimated as 262.05, 3.76, 0.050 for birds housed in battery-type conventional cages, 228.12, 3.57, 0.042 for birds housed in conventional floor cages, and 252.53, 3.86, 0.045 for birds housed in enriched floor cages, respectively. Among the bilateral traits, the highest mean value of relative asymmetry was found for wing length of birds reared in conventional battery type cages (P<0.01). As a result, it was determined that quails raised in conventional battery type cages are more advantageous for economic production. However, it may be recommended to use enrichment objects for an animal welfare oriented production system.

    IPARD supports positively affect hematological parameters, milk production, and welfare indicators of dairy cows
    (Ankara Üniversitesi Veteriner Fakültesi, 2022) Arı, Hikmet; Other; Other
    The study investigated body condition score (BCS), hematological parameters, metabolic profile indicators, total oxidant-antioxidant status, and milk yield (MY) of cows in non-funded (NF) and funded (F+) dairy farms by the European Union funds (under the Instrument for Pre-accession Assistance for Rural Development-IPARD) to support rural development. Sixty multiparous Holstein cows (110 to 209 days of lactation) from 3 NF and 3 F+ dairy farms were used in the experiment. Hematological parameters were within physiological limits in both dairy farms. Total erythrocyte count and percent hematocrit were higher in the F+ group. Serum non-esterified fatty acids (NEFA) level and aspartate aminotransferase (AST) activity were higher in NF farms compared to the supported ones. The serum triglyceride, total cholesterol, glucose levels, and gamma-glutamyl transferase (GGT) activity were higher for the cows in F+ farms. The average daily MY and BCS of cows in NF and F+ dairy farms were 15.8 L and 2.83, and 24.4 L and 3.11, respectively (P<0.01). The total antioxidant status (TAS) of cows in NF farms was significantly lower than F+ farms, whereas total oxidant status (TOS) was significantly higher for cows in NF farms. In conclusion, the grant support is important in establishing a more capable, more efficient, and more suitable infrastructure for animal welfare, and positively affects the physiological health and efficiency of animals in these dairy farms.
