“…We observed that the dressing percentage of the meat-type crossbred broiler and two breeds of yellow-feathered chicken in the current study was lower than that reported for Arbor Acres broilers [27]. However, the dressing percentage was higher in Mahuang chickens of 75 days as well as in Tuer chickens of 60 days and 75 days than in meattype crossbred broilers.…”

Indigenous chickens possess desirable characteristics and account for considerable proportions of the total chicken production in China. The current study examined the growth performance, carcass characteristics and muscle metabolites among a crossbred broiler and two indigenous, yellow-feathered chickens (Mahuang and Tuer) with different ages (60 and 75 days). Results indicated that the crossbred broiler had better feed efficiency, higher breast and thigh muscle yield, as well as a lower abdominal fat percentage than Mahuang and Tuer chickens (p < 0.05). Gas chromatography–mass spectrometry-based metabolomics and multivariate analysis revealed sugars, amino acids and organic acids were the predominant metabolites that differed among the three chicken breeds. Growth performance and carcass traits of yellow-feathered chickens exhibited significant differences with the extension of the feeding period (p < 0.05). Moreover, differential metabolites reflected altered aminoacyl-tRNA biosynthesis, ATP-binding cassette transporters, pantothenate and CoA biosynthesis, as well as glutathione metabolism in yellow-feathered chickens affected by age. Collectively, this study contributes to a deeper understanding of the production efficiency and chemical composition of precursor flavor in Chinese indigenous, yellow-feathered chicken.

“…Gross energy (GE) was measured with a calorimeter (C3000, IKA-WERKE Co., Ltd., Staufen, Germany). The AME (MJ/kg) was calculated according to the formula provided by Liu et al (2020) [ 38 ] and Karunaratne et al (2018) [ 39 ]. The following equations were used to calculate apparent nutrient digestibility and AME: Apparent nutrient digestibility (%) = 100 − [(TiO 2 in diet/TiO 2 in excreta or ileum digesta) × (Nutrient in excreta or ileum digesta/nutrient in diet)] × 100 AME (MJ/kg diet) = [Feed intake × GE in diet] − (Excreta output × GE in excreta)]/Feed intake …”

As an important food crop, cassava is rich in nutrients and high in starch content and is widely used in the production of industrial raw materials. However, the utilization value of cassava is limited due to the reduction of planting area and the existence of anti-nutritional factors. Therefore, we evaluated in vitro cassava starch digestibility and in vivo growth performance of broilers in a 3 × 3 factorial arrangement of treatments using three processing methods (mechanical crushing (MC), steam conditioning (SC), and puffing conditioning (PU)) and three conditioning temperatures (60, 75, and 90 °C) to screen for the optimal processing method and conditioning temperature to improve the utilization of cassava. In the in vitro cassava starch digestion study, the digestibility and digestion rate (p < 0.01) were higher at conditioned 90 °C than that at 60 or 75 °C, and PU was higher than SC and MC (p < 0.01) (0.25–2 h). The amylose content and amylose/amylopectin at conditioned 60 °C or PU were lower (p < 0.01) than that of 75 or 90 °C or SC, whereas the opposite was true for amylopectin content (p < 0.01). The resistant starch content of SC or PU was lower (p < 0.01) than MC. In the in vivo study, broilers fed diets conditioned at 60 °C or SC had a lower (p < 0.05) feed-to-gain ratio than those fed diets conditioned at 90 °C or PU diets. The ileum apparent digestibility of starch and AME were higher (p < 0.05) for broilers fed SC diets than for those fed MC diets. These results indicate that cassava starch promoted starch digestion rate by reducing amylose content and amylose/amylose under PU combined with a conditioning temperature of 60 °C, ileum digestibility of starch in broilers fed SC diets was higher than MC diets regardless of conditioning temperature, and SC diets increased AME and decreased F/G to promote growth performance of broilers.

“…El hígado de los tratamientos 80MA y 100MA fueron más grandes que el de las aves de los otros tratamientos, posiblemente debido al mayor trabajo hepático que tuvieron, porque el tejido adiposo de las aves sirve solo como un sitio de almacenamiento de grasa, y es en el hígado donde principalmente se sintetiza la grasa (Zhang et al, 2020). El tamaño de molleja no se vio afectado por las diferentes dietas, posiblemente debido a que todas tuvieron similar granulometría y el tamaño de partícula del maíz fue de 5 mm en todas las dietas.…”

El estudio tuvo como objetivo evaluar cinco niveles de sustitución del alimento de finalización con maíz amarillo en la dieta de pollos criollos y su efecto en el comportamiento productivo. Se distribuyeron aleatoriamente 96 pollos criollos machos mejorados de 70 días de edad en 6 tratamientos, cada uno con 4 repeticiones de 4 aves. Los pollos recibieron dietas con 0 (dieta control), 20, 40, 60, 80 y 100% maíz amarillo en sustitución del alimento finalizador. Los pollos de los tratamientos 0, 20 y 40%, en la fase de 70 a 112 días de edad, obtuvieron mayor ganancia de peso corporal y mejor conversión alimenticia. El rendimiento de carcasa del pollo disminuyó con 40, 60, 80 y 100% de sustitución con maíz amarillo en la dieta. La carcasa contenía menos grasa abdominal y peso de hígado con los tratamientos 0, 20 y 40%. En conclusión, el alimento de finalización para pollos criollos podría ser sustituido hasta en un 40% por maíz amarillo sin afectar el peso corporal, y hasta en un 20% sin disminuir el rendimiento de carcasa.
