Effect of Dietary Frying Fat, Vegetable Oil and Calcium Soaps Of Palm Oil on the Productive Behavior and Carcass Yield of Broiler Chickens

Abstract

Vegetable oils (VO) and animal fats are conventional lipid sources used in feed formulations. Frying fats (FF) and calcium soaps of palm oil (CaSPO) are low-cost lipid sources. This study evaluated the productive performance of broiler chickens fed diets with CaSPO in substitution for VO or FF. Two hundred, 1-day old male broiler chickens were allocated in a randomized design with factorial arrangement ( 22). Diets included 2 lipid sources (FF and VO) and 2 CaSPO levels (0 and 50%). The study had two phases (starter and finisher) of 21 days each. For the starter phase there was no effect (p>0.05) of dietary treatments on the chickens' productive performance. For the finisher phase birds fed diets with FF had higher feed intake and feed conversion ratio (main effect; p<0.01) than those fed diets with VO. Over the 42-day feeding period animals fed FF had higher feed conversion ratio (main effect; p=0.02) and tended (p=0.08) to show higher feed intake than those fed diets with VO. The CaSPO substitution for VO or FF had no effect (p>0.05) on the productive performance of broiler chickens. There was no influence of treatment on carcass yield. The drumsticks plus thighs were higher (main effect; p<0.01) in birds receiving VO than in those receiving FF. The interaction (fat source*CaSPO) was not significant (p>0.05). These results may indicate that VO is superior to FF and CaSPO may substitute for VO or FF without affecting productive performance of broiler chickens. Lipid source showed small influence on carcass characteristics.

Replacement of Conventional Vegetable Oil with Granulated Fats of Palm Oil (Prilled Fats and Calcium Soaps) in Broiler Chicken Diet: Performance and Carcass Traits

“…However, the final live weight was not influenced by CasPO level in the diet. In our previous work (Villanueva-Lopez et al, 2020), we reported similar productive performance in broiler chickens fed diets in which vegetable oil or recycled fats were replaced with CaSPO. We concluded that CaSPO represents an alternative to partially replace conventional vegetable oils (VO) in diets for broiler chickens, particularly in countries where CaSPO are cheaper than traditional VO; however, reports on this topic are very limited.…”

“…The inclusion of CaSPO in diets reduced broiler chickens' body weight gain and carcass weight. In contrast, Villanueva-Lopez et al (2020) reported beneficial effects of dietary CaSPO on the breast yield of broiler chickens. As previously mentioned, recycled fats were used , in the study of Villanueva-Lopez et al (2020), whereas this type of fats was not used in the present study.…”

Instead, PFPO was used, which might have higher energy density than recycled fats and reflect in carcass weight reduction of chickens fed CaSPO.…”

In our previous work (Villanueva-Lopez et al, 2020), we used CaSPO and recycled fats in the chicken´s diet, while the current study tested CaSPO and PFPO in chicken feeding. To the best of our knowledge, there is no previous research using PFPO in broiler chicken feeding.…”

Emulsifier in Diets with Different Alternative Lipid Sources: Effects on the Health of Japanese Quails

“…The use of vegetable oils and/or animal fat is essential in formulating poultry diets, as these sources help to achieve ideal levels of metabolizable energy (Villanueva-Lopez et al, 2020). Due to the high demand and diversified use of vegetable oils, not only for animal but also human use, the world market has faced difficulties in producing high quantities to supply these chains.…”
