Growth performance, digestibility, haematology, biochemistry, and some humoral immunity blood parameters of broiler chickens fed different levels of Boswellia serrata resin

Abstract

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P < 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P < 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P < 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P < 0.05; and Control vs BSR diets, linear, P < 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.

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 chickens selected for the slaughter were also assigned for blood sampling (two broiler chickens/cage). The blood sampling and hematological analyses of red blood cells (RBCs), packed cell volume (PCV), hemoglobin (HGB), mean cell volume (MCV), mean cell hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were described in a previous article [27]. The contents of calcium, magnesium, phosphorus, copper, iron, and zinc were determined in plasma without hemolysis sign using methods described in a previous article [28].…”

Effect of Dietary Boswellia serrata Resin on Growth Performance, Blood Biochemistry, and Cecal Microbiota of Growing Rabbits

“…Moreover, the broilers meat produced had lower fat content by diets supplemented with 3 or 4% BS (8,9). Interestingly, it has been recognized that BS has enormous benefits as a natural product: it does not cause any residue in animal meat, as well as increases globulin, lymphocytes and improves the animal immune response (9). This suggests that BS is a natural favorable product especially in tropical and subtropical regions when there is a threat to the immune system from pathogens to reduce the massive use of anti-biotics (8,9).…”

“…Boswellia serrata (BS) or frankincense from the Arabian Peninsula belonging to the Burseraceae family. It possesses various therapeutic activities, for example, bactericidal and anti-inflammatory properties, due to the precence of many aromatic compounds with boswellic acid the most active molecule (5)(6)(7)(8)(9). Mono and diterpenes, ethyl acetate, octyl acetate, and methylanisole are natural anti-oxidants that constitute the major components of BS (5,6).…”

“…Mono and diterpenes, ethyl acetate, octyl acetate, and methylanisole are natural anti-oxidants that constitute the major components of BS (5,6). Application of the BS as a phytogenic in broiler diet can increase productive performance and enhance quality of meat (5,6,8,9). Al-Yasiry et al (8) reported that broiler chickens that were fed diets containing different levels of BS (0, 3, 4, or 5%) have increased significantly in their body weight, feed efficiency and absorption thereby, enhanced growth performance.…”
