Effect of Boswellia serrata Resin Supplementation on Basic Chemical and Mineral Element Composition in the Muscles and Liver of Broiler Chickens

Abstract

Supplementation of broiler chicken diets with resin rich in bioactive components, such as different boswellic acids, could improve productivity, chemical composition, and nutritive value of produced meat. The aim of the study was to assess the effect of different levels of Boswellia serrata (BSR) supplementation in broiler chicken diet on the basic chemical composition and the Ca, P, Mg, Fe, Zn, and Cu contents in the breast and drumstick muscles and liver. The analyses involved 200 Ross 308 chickens. The broiler chickens were fed with diets containing 0 (BSR0), 1.5 (BSR1.5), 2 (BSR2), and 2.5% (BSR2.5) of B. serrata resin. The supplementation of broiler chicken diets with 2.5% (BSR2.5) decreased linearly the ether extract in breast and drumstick muscles and the calorific value in drumstick muscles (P < 0.05). An increased level of Ca in the breast and drumstick muscles (control vs. BSR diets, linear, P < 0.05) and in the liver (control vs. BSR diets, quadratic, P < 0.05) as well as Mg in the drumstick muscles and liver (control vs. BSR diets, linear, P < 0.05) was noted in the BSR2 and BSR2.5 chicken groups. The BSR supplementation reduced Cu (in the breast and drumstick muscles and liver) (P < 0.05) and Zn retention (in the drumstick muscles) (C vs. BSR, linear, P < 0.05). B. serrata resin can be considered a good feed additive with a positive impact on the dietary value of poultry meat.

Inclusion of Camelina, Flax, and Sunflower Seeds in the Diets for Broiler Chickens: Apparent Digestibility of Nutrients, Growth Performance, Health Status, and Carcass and Meat Quality Traits

“…The content of dry matter and basic nutrients in the ground oilseed samples (250 g seeds/variety) was determined according to standard AOAC procedures [20] described in Section 2.4.1. Results are the average of 9 samples in three replicates, 1 Calculated by Kjeldhal nitrogen N × 6.25, 2 SFA-Saturated fatty acid, 3 MUFA-Monounsaturated fatty acids, 4 PUFA-Polyunsaturated fatty acids, 5 Fresh sample.…”

“…Total P content was determined colorimetrically [34]. The individual stages of chemical determinations were described in previous articles [1,2].…”

“…Table 6. Correlation coefficients between basic nutrients and mineral elements in the camelina, flax, and sunflower seeds and the breast and drumstick muscles of broiler chickens fed a control, camelina, flax, and sunflower diet (r) 1 There were mainly strong correlations between the contents of the basic nutrients and elements in the seeds and in the breast and drumstick muscles. High positive and negative correlations (r > 0.6) were observed mainly between the nutrient content in the chicken muscles and camelina seeds: Ca, Mg, P, Cu, Fe, Zn, and fat, in the chicken muscles and flax seeds: Ca, Mg, P, Cu, Fe, Zn, fat, and crude ash, and in the chicken muscles and sunflower seeds: Ca, Mg, P, Cu, Fe, Zn, and fat (p < 0.05).…”

“…The primary aim of animal production is to provide high nutritional and dietary value of meat, which mainly depends on its chemical composition. Currently, attention is paid not only to the content of essential nutrients but also to the content of minerals and biologically active substances [1,2]. The quality of final products, like meat quality, in large-scale poultry production is ensured mainly through appropriate optimization of the composition of poultry diets [3].…”

Nutrient and Mineral Profile of Chosen Fresh and Smoked Fish

“…The awareness of consumers in this area is low. To ensure protein in the diet, consumers usually choose animal meat [5] or legume seeds [6]. The content of protein and other nutrients in fish meat may vary between species, sex, and even the season of the year [7].…”
