    Effects of Alchemilla vulgaris on growth performance, carcass characteristics and some biochemical parameters of heat stressed broilers
    (Hellenic Veterinary Medical Soc, 2020) Koseman, A.; Akdemir, F.; Uremis, N.; Seker, I; Turkoz, Y.
    This study aimed to investigate the effects of Alchemilla vulgaris (A. vulgaris) on growth performance, carcass characteristics, and biochemical parameters in broilers exposed to high environmental temperature conditions. A total of 45 broilers of 21 days of age (Ross 308) were used and grouped as the control group (C), and the groups with the addition of 1% (G1), or 3% (G2) A. vulgaris to chicken diet, respectively. In this study, the body weights of heat stressed broilers were significantly different on the 35th day and onwards. Feed intake was higher in the control group. Feed conversion ratio (FCR) was better in groups G1 and G2 compared to control on the 36th and 42nd day, the FCR was better on the 21st-42nd days. The highest hot and cold carcass performance were observed in group G2 (79.72 +/- 0.93% and 78.02 +/- 0.99, respectively), and the lowest values were observed in group C (76.26 +/- 1.13% and 75.70 +/- 1.20%, respectively). A. vulgaris, reduced serum malondialdehyde (MDA) levels as numerically, and suppressed lipid peroxidation in a dose-dependent manner. It had significant effects on monocytes (MON %, MON count), platelets (PLT), and plateletcrit (PCT) parameters only. In conclusion, the deleterious effects of high environmental temperature in broilers could be partially reversed by A. vulgaris addition to the diets between days 21 and 42.

    Effects of Alchemilla vulgaris on haematology and antioxidant status of heat- stressed quails during the late laying period
    (Hellenic Veterinary Medical Soc, 2021) Koseman, A.; Akdemir, F.; Uremis, N.; Seker, I; Turkoz, Y.
    The effects of Alchemilla vulgaris (AV) on haematology and serum, liver, and ovarian antioxidant status of heat-stressed quail in the late laying period were observed in this study. A 2x3 factorial design was used with 0, 1 and 3% AV fed in thermoneutral (TN) and heat stress (HS) conditions. A total of 150 quails were randomly assigned to six groups. The quails were located in temperature controlled rooms. The mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and platelet distribution width (PDW) obtained in quail fed 1% AV were higher than in 3% AV under both TN and HS conditions. Comparing 3% AV to 1% AV, the concentration of MCH obtained for 1% AV was higher in HS and lower in TN conditions. Besides, quails fed for 1% AV had a lower procalcitonin (PCT) value in HS than 3% AV but this PCT value was the same in TN. The serum malondialdehyde (MDA) was lower in 1% AV than 3% AV in both HS and TN. The ovarian MDA was lower in TN than HS. In both TN and HS conditions, the ovarian MDA value was determined higher for 1% AV than for 3% AV. The liver glutathione (GSH) value was higher in 1% AV than 3% AV in both TN and HS conditions. The Total Oxidant Capacity (TOS) value was found higher for 3% AV in TN and 1% AV in HS. The serum GSH, TOS, and oxidative stress index (OSI) values were lower for 3% AV compared to 1% AV for both TN and HS conditions, whereas for MDA value this was the opposite. The ovarium MDA and TOS values were lower for 3% AV than for 1% AV in both TN and HS. Also, the liver MDA, GSH, and Total Antioxidant Capacity (TAS) values were lower for 3% AV than for 1% AV in both TN and HS conditions. Finally, dietary AV has been shown to have a partial antioxidative effect on the defense system and also has effect on red blood cell profiles and platelet counts rather than white blood cell profiles.
