“…Phytogenic compounds from plants are considered one of the most effective solutions to inefficiencies in poultry production (Wallace et al, 2010). Over the last two decades, substantial interest has arisen in bioflavonoids, a group of secondary plant metabolites, as an alternative to growth-promoting antibiotics in poultry feedstuffs (Kamboh et al, 2015;Kamboh et al, 2019).…”

The effect of dietary genistein on performance, intestinal morphology, caecal Lactobacillus spp. count, and tibia composition in broiler chickens after 21 and 37 days of feeding was investigated. A total of 360 Cobb 500 broiler chickens (21 days old) were randomly allocated to five treatments with six replicates of 12 birds each. They were fed a basal diet (C) or a basal diet supplemented with 200 (T1), 400 (T2), 600 (T3) and 800 (T4) mg genistein/kg of feed. Genistein supplementation did not affect feed intake, but improved bodyweight, weight gain and feed conversion ratio (FCR) after 21 days, while 600 mg/kg led to a significant increase in FCR after 37 days of feeding. Plasma triglyceride level decreased with dietary genistein after 21 days, while increases were found in T3 and T4 groups after prolonged supplementation. Significantly improved duodenal and jejunal villus length and width, crypt depth and villus/crypt ratio were observed after the first and the second finishing periods, respectively, while adverse effects were found in the ileum for both periods. At 42 days old, greater spleen and heart weights were measured in broilers fed diets with 800 mg/kg than in other broiler groups. The shorter genistein supplementation period (21 days) of 200 and 400 mg/kg had a positive effect on tibia wet weight, ash and calcium (Ca) content, while 37 days of the higher genistein doses administered to the T2, T3 and T4 birds significantly increased caecal lactic acid bacteria (LAB) counts. Thus, recommended doses should not exceed 400 mg/kg. Keywords: broiler performance, blood triglyceride, Lactobacillus, prolonged fattening, small intestinal morphology

“…The mechanism of action of extracts may be related to the absorption and deposition of the phenolic compounds because, when absorbed, they are quickly metabolized, and a large part is eliminated by the kidneys (Lee et al 2004). Kamboh et al (2019) emphasized that the unabsorbed flavonoids from the small intestine, and some of the absorbed compounds, are secreted with bile, being after being degraded in the large intestine by the microbiota. Rupasinghe et al (2010) observed that quercetin glucosides, which belong to a subgroup of flavonoids, can be absorbed and metabolized by broiler chickens.…”

This article assessed the performance, carcass yield, and meat quality of finishing broilers fed increasing levels of hydroethanolic extract of guavira fruit peel (HEGP) were assessed. A total of 480, three-weeks-old male broilers were randomly allocated to dietary levels of HEGP (0, 100, 200, 300, 400, and 500 mg/kg), with five replicates and 16 birds each. There was a quadratic effect of HEGP inclusion on weight gain (WG) and feed conversion ratio (FCR), with the greatest WG and FCR being calculated at levels of 314 and 219 mg/kg HEGP, respectively. Broilers fed diets containing the extract had better performance than those fed an extract-free diet. There was no effect of extract inclusion on carcass yield and cuts. There was a quadratic effect of HEGP inclusion on a* (redness) of thigh meat at 15 min post-mortem, and on water-holding capacity (WHC), with the lowest and highest values being calculated at 270 mg/kg and 263 mg/kg HEGP, respectively. There was a quadratic influence of HEGP inclusion on the malonaldehyde content at 30-day storage, with highest value being calculated at 218 mg/kg HEGP. Dietary inclusion of 219 mg/kg of HEGP resulted in better FCR for broilers in the finishing phase but without improvement in meat quality.

“…Se ha informado de los efectos benéficos que los flavonoides, entre ellos las antocianinas, ejercen sobre la producción avícola (Kamboh et al, 2019). Así, la suplementación con 0.15 y 0.75% de un EMM, como fuente de antocianinas, mejoró el peso de las aves a los 56 días de edad, con relación al grupo control no tratado.…”

El objetivo del presente estudio fue determinar el efecto de la suplementación en la dieta de pollos de engorde de dosis crecientes de un extracto de maíz morado (Zea mays L) sobre el desempeño productivo y metabolismo lipídico. Se utilizaron 200 pollos de engorde COBB 500, sin sexar, de 28 días de edad distribuidos aleatoriamente en cuatro tratamientos: T1 (control), T2, T3 y T4 con 0, 0.05, 0.15 y 0.75% de extracto de maíz morado (EMM) como fuente de antocianinas. Se evaluó el desempeño productivo, perfil lipídico, indicadores de riesgo cardiovascular (colesterol total/colesterol de lipoproteínas de alta densidad - CT/c-HDL- y colesterol de lipoproteínas de baja densidad/c-HDL - c-LDL/c-HDL), glucemia y esteatosis hepática (EH). Diez pollos macho por tratamiento fueron sacrificados a los 56 días de edad. Los resultados se analizaron mediante ANOVA de una vía y prueba de medias de Dunett, excepto el indicador de riesgo cardiovascular CT/c-HDL (prueba no paramétrica de Kruskal-Wallis) y prueba exacta de Fisher para comparar las proporciones de EH entre los tratamientos control y suplementados con EMM. El peso final fue mayor en T3 y T4 con relación a T1 (p=0.045), mientras que el peso en canal, rendimiento en canal y peso relativo de grasa abdominal no fueron diferentes entre tratamientos. Tampoco hubo diferencias entre tratamientos respecto a las concentraciones séricas de triacilglicerol (TAG), CT, c-LDL, c-HDL y glucemia. Sin embargo, los índices de riesgo cardiovascular CT/c-HDL y c-LDL/c-HDL y la proporción de EH fueron menores al suplementar con el EMM (p<0.05). Los resultados sugieren que el EMM ejerce un efecto protector frente al riesgo cardiovascular y esteatosis hepática, sin afectar el desempeño productivo de las aves.
