Nigella seed oil as alternative to avilamycin antibiotic in broiler chicken diets

Abstract

This study was conducted to study the effect of nigella seed oil as an alternative to the antibiotic, avilamycin, on growth, digestibility, muscle fatty acid profile and some physiological parameters in broiler chickens. Fifty four chicks at 15 d of age (average weight, 320 ± 3 g) were divided into a control group and two treatment groups (n = 18). The control group was fed a basal diet and the experimental treatment groups were fed the basal diet supplemented with avilamycin at a level of 0.001% or nigella seed oil at 1 mL/kg. Growth performance and breast muscle fatty acid profile were measured. Although feed intake was not affected, bodyweight gain was increased, and thus feed conversion ratio was improved by feeding nigella seed oil compared with the control and avilamycin groups. Plasma total cholesterol and low-density lipoprotein cholesterol (LDL-C) concentrations were higher, while, plasma high-density lipoprotein cholesterol (HDL-C) acid level was lower and polyunsaturated fatty acid levels were higher in the muscle fat of birds receiving nigella seed oil than those receiving the other treatments. It is concluded that feeding nigella seed oil as alternative to avilamycin antibiotic improved growth performance, modified the fatty acids profile in muscles and enhances plasma total cholesterol, LDL and HDL concentrations, and glutathione peroxidase (GSH-Px) activity.

Effect of a phytogenic additive on blood serum indicator levels and fatty acids profile in fattening turkeys meat

“…Furthermore, no increase in serum concentration of ALT and AST may provide evidence to protect of liver against hepatocellular degeneration (Al-Jaff, 2011). The presented study confirmed previous results (Habibi, et al, 2014;Saleh, 2014;Zhu, et al, 2014) on the decreasing effect of phytoadditives on the activities of plasma ALT and AST in animals. Meanwhile, Abd ElGhang and Ismail (2013) who used oregano essential oil in broiler feed, observed increase in the activity of ALT and AST.…”

“…In our study, significantly higher (P <0.01) concentration of ALT as well as AST was found in turkey of control group (53.963 and 6.238 U/l), while lower concentration was found in birds from experimental group (3.499 and 1.012 U/l). The lowest activities for Gálik et al: Effect Of A Phytogenic Additive On Blood Serum Indicator Levels And Fatty Aci... plasma ALT and AST recorded for individuals fed diets supplemented with phytoadditive indicate that the used treatment did not negatively alter liver enzyme activity but also had a non-toxic effect on the kidneys and liver (Saleh, 2014). Furthermore, no increase in serum concentration of ALT and AST may provide evidence to protect of liver against hepatocellular degeneration (Al-Jaff, 2011).…”

The effect of essential plant oils on mineral composition of egg mass and blood parameters of laying hens

“…Furthermore, no increase in serum concentration of ALT and AST may provide evidence to protect of liver against hepatocellular degeneration (Al-Jaff, 2011). Presented experiment did not confirm results of other authors (Habibi et al, 2014;Saleh, 2014;Zhu et al, 2014). Shi et al (2014) who added phytosterols into feed mixture of layers reported some minor changes in clinical chemistry parameters, but these changes were small and considered to be of no toxicological significance.…”

“…In contrast to the present study, significantly higher concentrations of ALT as well as AST were found in the control group, while lower concentration was detected in birds from experimental group. The lowest activities for plasma ALT and AST recorded for individuals fed diets supplemented with phytoadditive indicate that the used treatment did not negatively alter liver enzyme activity but also had a non-toxic effect on the kidney and liver (Saleh, 2014). Furthermore, no increase in serum concentration of ALT and AST may provide evidence to protect of liver against hepatocellular degeneration (Al-Jaff, 2011).…”

Comparison of the effects of basil (&lt;i&gt;Ocimum basilicum&lt;/i&gt;) essential oil, avilamycin and protexin on broiler performance, blood biochemistry and carcass characteristics

“…This result is in agreement with the results of Ceylan and Ciftci (2003), Chowdhury et al (2009) and Eseceli et al (2010), who reported that there was no significant effect on carcass weight in broiler chicks fed a diet supplemented with avilamycin. Similarly, Saleh (2014) reported that supplementation with avilamycin did not significantly affect the liver weight of broilers.…”
