Kaya, Hacer
Background: The present experiment was conducted to investigate the effect of heat stress (HS) and hawthorn (Crataegus oxyacantha) fruit extract (HFE) on performance, carcass characteristics and serum parameters in broiler chickens. Methods: Experimental treatments included two different ambient temperatures (24°C: thermoneutral conditions, or 35°C: HS conditions) and three different HFE (0, 0.2 and 0.4 ml/L) in a 2×3 factorial arrangement. A total of 300 1-day-old broiler chicks were randomly allotted 1 of 6 treatments with five replicates. A total of 300 1-day old broiler chicks were randomly allocated to 6 groups with five replications of 10 birds each. HFE supplementation had no effect on growth performance, carcass characteristics and visceral weight in stressed groups (P>0.05). It was also determined that it has a lowering effect on serum malondialdehyde (MDA), free fatty acid (FFA), triacylglyceride (TAG), total lipid (TL) and low density lipoproteins (LDL) (P<0.05), but it has no effect on other parameters (P>0.05). Result: As a result, it is thought that the addition of HFE to the drinking water of broiler chickens exposed to HS has no effect on the performance characteristics, HFE has a hypolipidemic effect and would be beneficial in order to strengthen the immune system.

Kaya, H.
Background: This study, it was aimed to determine the effects of adding organic hawthorn (Crataegus tanacetifolia) fruit vinegar (HFV) in different doses to the drinking water of broiler chickens reared under cyclic heat stress (CHS) on performance, carcass characteristics and some serum parameters. Methods: In the study, 300 one-day-old broiler chickens (Ross 308), after a 1-week acclimation period, were tested in two different (24 and 35◦C) ambient temperatures and three different HFV levels (0, 2 and 4 ml/L) according to the 2×3 factorial experimental design. Chicks were randomly distributed to 6 experimental groups with 5 replications, with 10 animals in each replication. The addition of organic HFV to the drinking water of broiler chickens subjected to CHS didn’t affect growth performance, carcass characteristics and visceral weight (P>0.05). Addition of HFV increased serum FFA level, decreased serum MDA, HDL and TAG levels (p<0.05) and did not affect other serum parameters (P>0.05) in CHS-treated groups. Result: As a result, it was concluded that the addition of HFV to the drinking water of broiler chickens exposed to cyclic heat stress did not have any negative effect on growth performance, carcass characteristics and visceral weights, but it could be beneficial in preventing lipid peroxidation.
