Effect of banana weevil enriched with β-glucan from Saccharomyces cerevisiae on productivity and abdominal fat of broiler chickens

The aim of this study was to assess the effect of low environmental temperature on growth, feed conversion, performance and selected biochemical and haematological indicators in broiler chickens. The decrease in air temperature since the 22nd day of growth influenced significantly (p < 0.05) the level of total proteins, uric acid, phosphorus (in female broiler chickens), glucose (in male broiler chickens), haemoglobin (in female broiler chickens) and liver weight (in male broiler chickens). The temperature influenced significantly (p < 0.01) the level of triiodothyronine, haemoglobin (in male broiler chickens), haematocrit, abdominal fat content (in male broiler chickens), and heart weight too. The results have clearly confirmed that during growth, the decrease in environmental temperature (cold stress) negatively influenced some indices of performance and blood system in broiler chickens.

Level Of Significance

This study was conducted in Chimborazo province, Riobamba Canton to evaluate the effect of threonine and the bioactive component of Saccharomyces cerevisiae on the productive performance of the broiler Cobb 500. A total of 270 one-day-old broiler chicken of both sexes were included, which corresponded to an experimental unit size of 15 birds. Two growth promoters were used for the treatments -- T1: Threonine (aminoacid) 200 g/Tn; and T2: bioactive oligosaccharides, obtained from the cell wall of selected strains of S. Cerevisiae (probiotic) 750 g/Tn. These were compared to a control group. The data were analyzed through Analysis of Variance (ADEVA). The separation of means was performed using the Tukey statistic at a level of significance of p < 0.05 and p < 0.01. The data were processed using the Infostat software version 2010. The results showed that the best productive yields were with treatment 2; the values for this treatment were: weight at 28 days: 1369.42 g; weight gain at 28 days: 48.90 g; food conversion at 28 days: 1.39 points; carcass weight: 2527.05 g; and yield to the carcass: 83.85%. Through the economic analysis, it was determined that the highest cost-benefit index was 1.30 USD with the application of T2. So according to the results, a better use of the nutrients that are present in the feed is achieved when bioactive components of S. cerevisiae are supplied in the diet of broiler chickens. Keywords: Threonine, Saccharomyces cerevisiae, productive performance, broiler, Cobb 500. RESUMEN Se realizó un experimento en la provincia de Chimborazo, Cantón Riobamba, para evaluar los efectos de treonina y componentes bioactivos de Saccharomyces cerevisiae sobre el comportamiento productivo en aves Cobb 500. Se utilizaron 270 pollitos mixtos Cobb 500 de un día de edad de ambos sexos, con un tamaño de unidad experimental de 15 aves. Para los tratamientos se manejaron dos promotores de crecimiento, T1: Treonina (aminoácido) 200 g/Tn y T2: Oligosacáridos bioactivos, obtenidos a partir de la pared celular de cepas seleccionadas de S. Cerevisiae750 g/Tn; frente a un testigo (T0). Los datos obtenidos fueron sometidos a Análisis de Varianza (ADEVA); la separación de medias se realizó mediante el estadístico Tukey a un nivel de significancia (p < 0,05) y (p < 0,01); los datos se procesaron mediante el software Infostat versión 2010. Los resultados muestran los mejores rendimientos productivos con el Tratamiento 2, para los parámetros: peso a los 28 días 1369,42 g; ganancia de peso a los 28 días 48,90 g; y conversión alimenticia a los 28 días con 1,39 puntos; así como peso a la canal 2527,05 g; y rendimiento a la canal 83,85%. Mediante el análisis económico se determinó que el mayor índice beneficio costo fue de 1,30 USD con la aplicación del T2. Lo que brinda un indicativo que mediante el suministro de componentes bioactivos de S. cerevisiae en la dieta de pollos broiler, se logra un mejor aprovechamiento de los nutrientes que se encuentran presentes en el alimento, lo que se refleja en los parámetros productivos.

This study aims to examine the use of red sweet potato flour on slaughter weight, percentage ofcarcass weight, and abdominal fat in broiler chickens fed with additional red sweet potato flour. Thisresearch was conducted in April to May 2018, housed in the Raman Farm enclosure in Puosu JayaVillage, Konda District, Konawe Selatan District. The material used in this study was 64 weeks oldbroiler chickens, with 64 feed ingredients used as the concentrate, corn, bean, sweet potato flour. Theequipment used is a scale, a colony cage made of wire-lined wood and measuring 4m x 2m, which isdivided into 16 plots and the size of each 1m x 0.5m, each story is equipped with a place to eat anddrink, 40-watt incandescent balloons and other equipment such as scales, ovens, sample grinders,basins, plastics, and gutters. This study was designed using a complete randomized design with fourtreatments and four replications, where four treatments consisted of P0 basic ration (Control), P1:basic ration containing 4% red sweet potato flour, P2: elemental percentage containing 6% red sweetpotato flour, and P3: basic ration contains 8% red sweet potato flour. The variables observed in thisstudy were cutting weight, carcass percentage, and abdominal fat of broiler chickens. The results ofthe analysis of variance showed that the administration of red sweet potato flour had no significanteffect (P> 0.05) on the percentage of carcasses and abdominal fat of broiler chickens. Broiler chickenaged five weeks. It was concluded that the provision of different red sweet potato flour in feed did notsignificantly affect slaughter weight, carcass weight, and abdominal fat percentage of broilerchickens. There is a tendency for broilers fed with red sweet potato flour to have heavier cut weights,a more significant portion of carcasses and an increase in the level of red yam, and a decrease inabdominal fat content and the addition of red yam levels in the feed.

Maintenance Requirements

Purpose of researches in feed restriction area is improvement of feed efficiency, decrease of carcass fat content and abdominal fat pad size (Plavnik and Hurvitz,1991).Birds after early life feed restriction have less maintenance requirements due to decrease of heat increment and decrease of basal metabolic rate and specific dynamic action of food (Forsum et al.,1981).In many investigations, compensatory growth have not observed (Summers et al.,1990).It seems administration of Thyroid hormone after feed restriction can induce compensatory growth. The objective of the present study was to investigate the effect of early feed restriction and L-Thyroxin administration after early feed restriction on compensatory growth in broiler chickens.
