Fatty acids profile of breast and thigh muscles of broiler chickens fed diets with propolis and probiotics

Abstract

The aim of the study was to assess the effect of supplying propolis extract separately and propolis extract together with probiotics based on Lactobacillus fermentum on fatty acids (FA) composition of the most valuable parts of chicken carcass. Diets enriched with 400 mg propolis extract per 1 kg of feed mixture and 400 mg propolis extract per 1 kg of feed mixture plus 3.3 g probiotic preparation added to drinking water (E1 and E2 groups, respectively) were given to broiler chickens throughout a 42-d growth period. After slaughter, the FA profiles of breast and thigh samples were determined. Both supplemented diets decreased the total amount of saturated FA (SFA), mainly because of the myristic (C14:0) and stearic (C18:0) acid contents in both breast and thigh muscles. However, a significant decrease (P ≤ 0.05) in SFA was confirmed only in thigh muscle. Supplementation with propolis together with probiotics (E2) significantly increased (P ≤ 0.05) monounsaturated FA (MUFA) contents in breast muscle. Particularly oleic acid (C18:1 cis) contributed to an overall increase in MUFA. A rise (P ≤ 0.05) in polyunsaturated FA (PUFA) in breast muscle was, however, associated with the dietary supplementation of propolis extract separately (E1). A similar trend (P  0.05) for MUFA and PUFA levels was also observed in thigh muscle. Of all PUFAs detected in breast and thigh muscles, linoleic acid (C18:2 cis) was found at the highest levels. Its levels varied from 11.34 to 12.02 g*100 g -1 and from 11.05 to 11.82 g*100 g -1 in breast and thigh muscles, respectively. The highest level (P ≤ 0.05) of linoleic acid was observed in group E1. Comparing breast with thigh muscle, the breast was demonstrated to contain more SFA and PUFA, but less MUFA proportions. Although the n-3 PUFA:n-6 PUFA ratio was similar among the treatments in both breast and thigh muscles, n-6 PUFA:n-3 PUFA ratio has been showed to be a significantly lower (P ≤ 0.05) in thigh muscle, 1179Journal , 17(4), p.1179-1193 DOI: 10.5513/JCEA01/17.4.1828 with the lowest ratio found in E2 group. Differences in n-6 PUFA:n-3 PUFA ratio in breast were, however, not significant (P  0.05) between the treatments. On the whole, the present study indicated that propolis applied through the feed either separately or together with probiotics applied through the water had favourable effect on fatty acids profile in the most valuable parts of chicken carcass and could be thus added to diets for broiler chickens.of Central European Agriculture, 2016, 17(4), p.1179-1193 1179 Journal of Central European AgricultureKeywords: breast, broiler chicken, fatty acid, probiotic, propolis, thigh Abstrakt Cieľom štúdie bolo posúdiť vplyv propolisového extraktu aplikovaného samostatne alebo v kombinácii s probiotikom na báze Lactobacillus fermentum na obsah mastných kyselín v najcennejších častiach jatočného tela kurčiat.

Probiotics and potential applications for alternative poultry production systems

“…Following probiotic administration to broilers, the reduction of cholesterol and fat content in the breast and thigh meat was observed ( Hossain et al., 2012 ). Additional studies report increased fatty acids in broiler meat and higher levels of vitamin E and other nutrients ( Trembecká et al., 2016 ). Access to pasture or insects may also contribute to the organoleptic quality of the product, which could impact market acceptability for pasture reared and free-range poultry products ( Ponte et al., 2008 ; Hammershøj and Johansen, 2016 ; Ruhnke et al., 2018 ).…”

Nutritional Composition of Bombyx mori Pupae: A Systematic Review

“…Furthermore, lowering the n-6/n-3 ratio in broiler diets has been shown to improve growth performance and immune response in these birds [ 50 ]. In the case of other farmed animals’ meat, n-6/n-3 values of 1.3, 2.1, 7.2, and 13.7 were found in the muscle tissues of sheep, cattle, pigs, and chickens, respectively [ 51 , 52 ]. The n-6/n-3 ratio is always lower in marine species such as herring, tuna, pollock, salmon, and rainbow trout because their diet is based on marine phytoplankton [ 53 ].…”

Omega‐6: Its Pharmacology, Effect on the Broiler Production, and Health

“…However, linolenic acid and linoleic acid are necessary fatty acids that must be ingested [14]. Additionally, high amounts of polyunsaturated fatty acids undergo autoxidation far more rapidly than saturated PUFAs, particularly when exposed to heat, light, oxygen, and transition metals during manufacture, processing, and storage [15,16]. However, conjugated linoleic acids are sometimes misclassifed as omega-6 (abbreviated −6 or n − 6) fatty acids.…”
