- MakaleAçık Erişim2025Response of tibia bone morphology, biomechanics and minerals to Organic Hawthorn (Crataegus tanacetifolia) Fruit Vinegar application in broiler chickens exposed to cyclic heat stress
Kaya, Hacer
This study aimed to determine the effects of adding different doses of organic hawthorn fruit vinegar (HFV) to the drinking water of male broilers (Ross 308) reared under cyclic heat stress (CHS) on tibia bone morphology, biomechanics, and minerals. Broilers were distributed into six groups based on a 2 × 3 factorial design, testing two ambient temperatures (24 and 35°C CHS for 8 h/day starting from day 21) and three HFV levels (0, 2, and 4 ml/L). Cyclic heat stress had no effect on the morphological and biomechanical properties of the tibia bone, except for a decrease in cortex thickness (P < 0.05). However, CHS significantly decreased the bone Ca, P, Mg, Cu, Zn, Mn, and K levels, while increasing the Fe levels (P < 0.01). The addition of 2 and 4 ml/L HFV had no effect on the morphological and biomechanical properties of the tibia bone (P > 0.05), except for an increase in bone diameter with 2 ml/L HFV (P < 0.05). HFV additions were not sufficient to increase the Ca level decreased by CHS, and the tibia bone Ca level of birds under CHS decreased further with HFV additions (P < 0.01). Conversely, 2 ml/L HFV increased Mg levels, and both 2 and 4 ml/L HFV increased Cu, Fe, Zn, and Mn levels, whereas P levels decreased (P < 0.01). K level decreased with 2 ml/L HFV and increased with 4 ml/L HFV supplementation. In conclusion, HFV supplementation has positive effects on bone mineralization in broilers exposed to HS and can be used up to 4 ml/L to mitigate the negative effects of heat stress.
- MakaleAçık Erişim2023The Effect of Organic Hawthorn (Crataegus tanacetifolia) Fruit Vinegar Supplement on Growth Performance, Carcass Characteristics and Some Serum Parameters in Broiler Chickens Subjected to Cyclic Heat Stress

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.
