Hayvansal Yağın Yağ Asitleri Kalsiyum Tuzunun Broyler Performansı, İç Yağın Yağ Asidi Kompozisyonu, Kemiklerin Biyomekanik Özellikleri ve Tibia Mineral Düzeyi Üzerine Etkisi

Abstract

This study evaluated the effects of a graded concentration of dietary calcium soaps of tallow (CST) supplementation on broiler performance, carcass characteristics, abdominal fat fatty acid profile, bone biomechanical properties, and bone mineral composition. One hundred and forty 11-d-old male broiler chickens were randomly allocated to 4 experimental groups with 5 replicate pens containing 7 birds per each. The birds received cornsoybean meal based diet and CST (CST0, CST10, CST20, and CST30, respectively) was included in the grower (0, 10, 20, and 30 g/kg) and finisher (0, 15, 30, and 45 g/kg) diet at the expense of vegetable acid oil and limestone. Dietary supplementations had no significant effect on BWG and FI during the entire experimental period. However, FCR was improved in CST0 and CST10 groups in comparison to those of the CST20 group from d 11 to d 42.According to the present study result, dietary supplementation of low level of CST significantly influenced intestinal microarchitecture of the jejunum and ileum by improving villus height/crypt ratio and villus height, respectively. Femur (P=0.001) and tibia (P=0.020) stiffness increased linearly with the increasing level of dietary CST. Tibia Ca (P=0.009) and P (P=0.009) concentration of CST10 and CST30 groups were lower than the CST0 group. Increasing levels of CST in diets significantly reduced the Fe and Mn concentrations in tibia samples. In conclusion, supplementation of CST has no detrimental effect on broiler performance parameters and might be used as an alternative dietary fat source in the broiler industry.

Effect supplementation of black soldier fly larvae oil (Hermetia illucens L.) calcium salt on performance, blood biochemical profile, carcass characteristic, meat quality, and gene expression in fat metabolism broilers

“…These findings reported that supplementation of BSFLO-SCa increased FCR, which is associated with decreased of FI and BWG with supplementation of BSFLO-SCa. These finding supported the observation of Çalik et al (2019) , who reported that calcium salt tallow ( CST ) increased FCR compared with control that caused by decreased of FI and BWG with the increased of level supplementation.…”

“…On the other hand, the problem with using liquid fat in developing countries is the need for proper facilities for mixing with solid feedstuff. Calcium salt form of fatty acids is a saponification process that may alleviate this problem, easy to handle ( Abd-ElhayGado and Elsebaai, 2017 ; Shahryari et al, 2021 ), higher stability and resistant to oxidation ( Çalik et al, 2019 ; Villanueva-Lopez et al, 2020 ).…”

Tibia properties in broilers raised on their own commercial diets with different growth rates and sex during a 10‐week rearing period

“…After bone measurements, tibia samples were defatted in chloroform and methanol (2:1) for 72 h (Çalık et al., 2019 ). Subsequently, tibia samples were dried for 12 h at 105°C and ashed overnight at 600°C to determine dry matter and ash percentage, respectively.…”

Egg mineral levels, hatching results and bone properties in embryos and chicks obtained from broiler breeders at different ages

“…After bone measurements, bone samples were defatted in chloroform and methanol (2:1) for 72 h for mineral analysis (Çalık et al, 2019). The concentrations of iron, zinc, potassium, calcium, phosphorus, magnesium and manganese in shell, yolk, albumen, yolk sac and bones were determined as in the feed.…”
