Effects of dietary supplementation with a combination of plant oils on performance, meat quality and fatty acid deposition of broilers

Abstract

ObjectiveThis study was to evaluate effects of mixed plant oils (identified as mixed oil 1 [MO1] and mixed oil 2 [MO2]) on performance, serum composition, viscera percentages, meat quality, and fatty acid deposition of broilers.MethodsA total of 126 one-day-old Arbor Acres male broiler chicks (weighing 44.91± 0.92 g) were randomly allocated to 1 of 3 treatments with 7 replicate pens per treatment (6 broilers per pen). Dietary treatments included a corn-soybean basal diet supplemented with 3% soybean oil (CTR), basal diet with 3% MO1 (a mixture of 15% corn oil, 10% coconut oil, 15% linseed oil, 20% palm oil, 15% peanut oil and 25% soybean oil; MO1), or basal diet with 3% MO2 (a combination of 50% MO1 and 50% extruded corn; MO2). The trial consisted of phase 1 (d 1 to 21) and phase 2 (d 22 to 42).ResultsCompared to CTR, broilers fed MO (MO1 or MO2) had greater (p<0.05) average daily gain in phase 1, 2, and overall (d 1 to 42), redness in thigh muscle, concentrations of serum glucose, serum albumin, saturated fatty acids (SFA) and n-6/n-3 polyunsaturated fatty acids (PUFA) ratio in breast muscle, while these broilers also showed lower (p≤0.05) drip loss and concentrations of C18:3n-3 and PUFA/SFA ratio in breast muscle. Broilers fed MO2 had higher (p<0.05) liver percentage, while broilers fed MO1 had lower (p≤0.05) feed conversion ratio in phase 1 and increased (p<0.05) contents of C18:2n-6, C20:5n-3, C22:6n-3, and n-3 PUFA in breast muscle compared to CTR.ConclusionMixed plant oils had positive effects on performance, serum parameters, meat quality, liver percentage and fatty acid deposition in broilers, which indicates they can be used as better dietary energy feedstocks than soybean oil alone.

Effects of replacing dietary Aureomycin with a combination of plant essential oils on production performance and gastrointestinal health of broilers

“…Antibiotic alternatives such as plant extract, probiotics, and antimicrobial peptides were well investigated over the past few years ( Miles et al., 2006 ). Compared with other alternatives, plant essential oils were broadly applied because of their easy acquisition and broad-spectrum antimicrobial properties ( Long et al., 2018 ). In the present study, the POC supplementation slightly promoted the FCR and reduced mortality and culling rates, these results were in line with those of the study by Amad et al.…”

“…The immunoglobulins (IgG, IgM and IgA) and tumor necrosis factor alpha (TNF-α) in serum were measured by an ELISA kit (IgG, IgM, IgA and TNF-α quantitation kit; Bethyl Laboratories, Inc., TX, USA). The serum total cholesterol, total triglyceride, low density lipoprotein cholesterol (LDLC), high density lipoprotein cholesterol (HDLC) and urea contents were measured in an automatic biochemical analyzer (RA-1000, Bayer Corp., Tarrytown, NY, USA) following the instructions of the corresponding reagent kits (Zhongsheng Biochemical Co., Ltd., Beijing, China) ( Long et al., 2018b ). The serum growth hormone, 5-hydroxytryptamine (5-HT) and β-endorphin (β-EP) contents measured by using a radioimmunoassay (Sn-96513, Shanghai, China).…”

THE PHYSIOLOGICAL ASPECTS OF THE SUPPLEMENTATION OF DIETS FOR BROILERS (Gallus gallus L.) WITH DIFFERENT VEGETABLE OILS

“…Отмечено положительное влияние сочетания растительных масел на качество животноводческой продукции. Так, при добавлении в рацион бройлеров 3 % смеси растительных масел (кукурузное, пальмовое, льняное, арахисовое и соевое) отмечали увеличение содержание глюкозы, альбумина, ω-6 и ω-3 жирных кислот в сыворотке крови, а также усиление окраски мышечной ткани по сравнению с вариантом, когда использовалось только соевое масло (23). При этом возраст мясной птицы не влиял на усвоение жирных кислот из рациона (24).…”

“…Следовательно, липидный состав рациона может модулировать состояние пищеварения и всасывания в желудочно-кишечном канале. Полученные другими авторами данные дают представление о наличии связей между липидным составом растительных масел и их функциональными различиями (10,23,28,29). Однако именно в наших исследованиях было впервые установлено, что активность липазы крови при изменении липидного компонента в корме изменяется одновременно с активностью фермента в панкреатическом соке (30).…”
