“…Orczewska‐Dudek and Pietras (2019) observed higher levels of ω‐3 PUFA and improved juiciness of breast meat while supplemented broiler diet with camelina oil. Similarly, substitution of lard by rapeseed oil increased the PUFA and decreased the ratio of ∑ω‐6:∑ω‐3 fatty acids and these changes were more pronounced for the adipose tissues than the breast muscles (Skrivan et al, 2000; Torquato et al, 2018). Additionally, feeding broiler chickens with pomegranate seed oil‐supplemented diet resulted in a substantial increment of CLA isomers into breast lipids (Szymczyk & Szczurek, 2016).…”

Total 288 Ross‐308‐day‐old male broiler chicks were randomly distributed into six dietary treatment groups in a two‐way ANOVA with 2 × 3 factorial arrangements (two factors, i.e., dietary protein and energy having two types of protein, e.g., plant, animal and three different sources of energy, e.g., soybean oil, rice bran oil and sunflower oil) to justify if animal protein‐soybean oil based broiler diet optimizes net profit at the expense of desirable ω‐6 fatty acids in the breast muscle of the broiler chicken. Average daily feed intake (ADFI), final live weight (FLW), average daily gain (ADG), feed efficiency (FE), carcass characteristics, cardio‐pulmonary morphometry, fatty acid profile of the breast muscle and cost‐benefit analysis were measured. Results indicated that animal protein significantly increased 4.27% FLW, 6.13% ADFI, 4.31% ADG and 2.93% wing weight. Accordingly, soybean oil increased 4.76% FLW, 3.80% ADG and 1.36% dressing percentage at the expense of 12.07% proventriculus weight compared with sunflower oil. The generalized linear model identified no interaction effects of the sources of protein and energy on overall performance of the birds. Replacement of vegetable protein by animal protein decreased 14.01% ∑ω‐3, 12.16% ∑ω‐6 and 12.21% sum of polyunsaturated fatty acids (∑PUFA) and concomitantly increased 10.82% sum of saturated fatty acids (∑SFAs) in the breast muscle (Pectoralis major). Accordingly, replacement of sunflower oil by soybean oil decreased 29.17% ∑ω‐3, 6.71% ∑ω‐6, 11.62% sum of monounsaturated fatty acids (∑MUFAs) and 7.33% ∑PUFAs and concurrently increased 18.36% ∑SFAs in the breast muscle of the broiler birds. It was concluded that animal protein‐soybean oil‐based broiler diet optimized net profit at the expense of desirable ω‐3 and ω‐6 fatty acids in the breast muscle of the broiler chicken.

“…Accordingly, incorporation of mustard oil, linseed oil or fish oil at 2% and 3% levels during starter and finisher phases enriched broiler meat with ω-3 PUFA without affecting sensory appraisals (Kalakuntla et al, 2017). the breast muscles (Skrivan et al, 2000;Torquato et al, 2018).…”
