Effect of Supplementing Olive, Blackseed and Flaxseed Oils on Growth Performance and Serum Biochemistry of Broiler and Economics of its Production

Abstract

This study was conducted to investigate the effect of olive oil, blackseed oil and flaxseed oil on growth performance and serum biochemistry of broiler chicks. Three hundred broiler chicks were grouped into 30 experimental units having 10 chicks each. Three levels (0.5, 1.0 and 1.5%) of each of the oils were offered to the chicks such that each treatment was replicated thrice. The chicks fed on basal diet served as a control. The data on weekly body weight gain, feed intake, weekly feed conversion ratio, Newcastle Disease (ND) and IBD titers, serum triglycerides, serum cholesterol, low density lipoproteins and high density lipoproteins were recorded. Overall weight gain (1720.6 g) was significantly (P<0.05) highest in the treatment group having 0.5% flaxseed oil. Highest value of titer (213.33) against ND was observed in the treatment having blackseed oil 0.5%. Results of serum triglycerides, serum cholesterol, low and high density lipoproteins showed no effect of these treatments. Overall results depicted that 0.5% flaxseed oil improves growth performance in broiler chicks.

Effect of Olive Oil Supplementation on Growth, Carcass Traits and General Health of Rabbits Under Heat Stress Conditions

“…In agreement with the obtained results in our study, Ashraf et al (2017) found that supplementation of olive oil, black seed oil and flaxseed oil on serum biochemicals of broiler chicks, involving lipid profile (serum cholesterol, triglycerides, HDL and LDL). This reduction may be due to presence of omega 6 fatty acids which have the ability to decrease the cholesterol level in blood serum, while omega 3 fatty acids decrease cholesterol and triglycerides levels (An et al, 1997).…”

“…This may be attributed to that growing rabbits at early age post-weaning required a transit period to adapt on increasing level of dietary fats. The present results agreed with Ashraf et al (2017), who investigated the effect of olive oil, blackseed oil and flaxseed oil on growth performance of broiler chicks. They found that, the heaviest weight was observed in the treatment having flaxseed oil 0.5%, followed by the treatment group having olive oil at levels of 1.0 and 0.5%, respectively.…”

“…During the whole experimental period (5-13 weeks), rabbits in G3 showed significantly (P<0.05) the best feed conversion rate and the highest PI, while the inferior trends was detected by control group (G4). In this respect, Ashraf et al (2017) found the best FCR in broiler fed olive oil 1.0% diet, followed by those fed flaxseed oil 0.5% and black seed oil 0.5%, respectively. Also, some authors found that vegetable oils improved performance of birds (Sultan et al, 2015;Awaad et al, 2016).…”

Black Seeds (Nigella Sativa Linn.) as Natural Feed Alternative in Poultry Production

“…A recent study by [37] indicated that treatment with BSs and curcumin decreased the risk of exposure to Infectious bursal disease vaccine, improved general health condition and immune status of chicks. With the same line, [57] was observed the highest value of the antibody titer of chicks against ND in the treatment feeding 0.5% BSso.…”

Effect of Different Dietary Sources of Oils on Growth Performance and Profile of Lipid, Testosterone and Fatty Acids in Rabbit Bucks.

“…In agreement with the obtained results of FSO as a source of n-3 fatty acids, Shams (2019) found insignificant effect of dietary olive oil supplementation (0.2, 0.4 and 0.6%) on concentration of total cholesterol, triglycerides, LDL and HDL in blood of growing rabbits. Also, Ashraf et al (2017) found insignificant effect of different dietary sources (olive oil, black seed oil and flaxseed oil) on serum cholesterol, triglycerides and HDL. Moreover, Zibaeenezhad et al (2017) observed that Castelli II index did not change following the feeding on fish oil or fresh fish in human.…”
