Influence of Dietary Substitution of Palm Oil by Rapeseed Oil at Different Levels on Growth Performance and Economics of Broilers

Abstract

Background: Fat and oil are commonly used in poultry diets to increase energy density and also to increase the palatability of feed, feed efficiency and for deposition of fat in broilers. Thus a study was proposed to find the effects of dietary replacement of saturated fatty acid rich palm oil (PO) by omega-3 rich rapeseed oil (RO) on growth performance and economics in broilers. Method: The growth performance feeding trial was conducted in 160 day-old broilers (vencobb 400) with four treatment groups (G1, G2, G3 and G4) with four replicates of ten chicks each. The basal diet (R1) was prepared with palm oil included at the rate of 1.5, 3, and 4.5 per cent in pre-starter, starter and finisher ration, respectively and fed to G1. The other treatment groups G2, G3 and G4 received R2, R3 and R4 experimental rations respectively. The experimental rations R2, R3 and R4 were prepared with rapeseed oil replacing 25, 50 and 100 per cent of palm oil which was included in R1. Result: The broiler ration prepared with rapeseed oil at 50 and 100 per cent level (G3 and G4) replacing palm oil showed increased body weight gain (P less than 0.01) and better feed conversion ratio (P less than 0.05) than G1 group. There was no significant difference in the feed intake among the different treatment groups. Profit per kg live weight in G3 (Rs.12.06) and G4 (Rs.11.14) was more than G1 (Rs.8.21) and G2 (Rs.6.57). The supplementation of omega-3 rich rapeseed oil had significantly improved the performance of broilers.

Effect of Dietary Supplementation of Linseed Oil and Natural Antioxidants on Production Performance, Fatty Acid Profile and Meat Lipid Peroxidation in Broilers

“…Conversely some studies stated that, dietary fatty acid profile influences better body weight gain in broilers fed with omega 3 rich oil sources like sunflower oil, canola oil and soya bean oil compared to saturated fat rich palm oil as presence of polyunsaturated fatty acids has better intestinal absorption due to hydrolysis of monoglyceride and micelle formation compared to saturated fatty acids (Poorghasemi et al, 2018). Similarly feeding of omega 3 rich rapeseed oil at 0.75 to 1.5% level was reported to improve the production performance in broilers (Sudharsan et al, 2020). In our study, the FCE in the birds of LOG diet was found best with highest ADG and total weight gain and lowest ADFI.…”

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

“…Regarding the saturation of fatty acids, palm oil has negatively affected the productive performance of broiler chickens compared with lipids with lower saturated fatty acids concentrations like sunflower oil (Khatun et al, 2018) or rapeseed oil (Sudharsan et al, 2021). However, reductions in productive performance in broiler chickens have not always been reported when diets contain saturated or free fatty acids.…”
