“…), por lo que la salud del tracto digestivo es el órgano clave para garantizar la eficiencia de uso del alimento y el responsable de garantizar el éxito financiero del negocio avícola. La combinación de la genética y la nutrición tienen una influencia decisiva en el desempeño productivo de los animales, por lo que el enfoque tradicional centrado en satisfacer las demandas de aminoácidos para lograr un buen desempeño productivo va cambiando, con tendencia hacia el incremento de las concentraciones de aminoácidos específicos, tales como metionina, lisina y treonina para mejorar la salud, la producción y la sostenibilidad avícola (Lee et al, 2023).…”

“…Methionine (Met), as the first limiting amino acid in poultry diets, serves not only as the vital building block of proteins but also possesses many functional roles [ 15 , 16 , 17 , 18 ]. As previous studies showed, the detrimental effects caused by coccidiosis on bone development were attributed to the elevated oxidative stress and imbalance between osteoclast and osteoblast activities [ 19 , 20 ].…”

This study investigated the effects of dietary methionine (Met) levels on the bone quality of broilers challenged with coccidia. A total of 600 fourteen-day-old male Cobb500 broilers were gavaged with mixed Eimeria spp. and randomly allocated into 10 treatment groups by a 2 × 5 factorial arrangement. Birds received normal protein diets (NCP) or reduced-protein diets (LCP), containing 2.8, 4.4, 6.0, 7.6, and 9.2 g/kg of Met. Data were analyzed via two-way ANOVA and orthogonal polynomial contrast. At 9 days post-inoculation (DPI), whole body bone mineral density (BMD) and bone mineral content (BMC) linearly decreased as Met levels increased (p < 0.05). For the femoral metaphysis bone quality at 9 DPI, BMD linearly decreased, and porosity linearly increased as Met levels increased (p < 0.05) in the cortical bone. The increased Met levels linearly improved trabecular bone quality in LCP groups (p < 0.05) while not in NCP groups. For the femoral diaphysis cortical bone at 6 DPI, LCP groups had higher BMD and BMC than NCP groups (p < 0.05). Bone volume linearly increased as Met levels increased in LCP groups (p < 0.05) while not in NCP groups. In summary, the results suggested that increased Met levels decreased the cortical bone quality. However, in the context of reduced-protein diets, the increased Met levels improved trabecular bone quality.

“…Besides, findings also suggest that dietary AA could also be used for their regulatory role in metabolism homeostasis, leading to the concept of functional AA 13 , 14 . Beneficial contributions to gastrointestinal integrity and the immune system can be achieved by increasing specific AA concentrations above the needs for production performance 15 . Functional AA protective effect on the digestive system during enteric challenges is related to their targeted actions on the four pillars of gut health (i.e.…”

To address the overuse of antimicrobials in poultry production, new functional feed ingredients, i.e. ingredients with benefits beyond meeting basic nutritional requirements, can play a crucial role thanks to their prophylactic effects. This study evaluated the effects of the supplementation of arginine, threonine and glutamine together with grape polyphenols on the gut integrity and functionality of broilers facing a stress condition. 108 straight-run newly hatched Ross PM3 chicks were kept until 35 days and were allocated to 3 treatments. Broilers in the control group were raised in standard conditions. In experimental groups, birds were administered with corticosterone in drinking water (CORT groups) to impair the global health of the animal and were fed a well-balanced diet supplemented or not with a mix of functional amino acids together with grape extracts (1 g/kg of diet—CORT + MIX group). Gut permeability was significantly increased by corticosterone in non-supplemented birds. This corticosterone-induced stress effect was alleviated in the CORT + MIX group. MIX supplementation attenuated the reduction of crypt depth induced by corticosterone. Mucin 2 and TNF-α gene expression was up-regulated in the CORT + MIX group compared to the CORT group. Caecal microbiota remained similar between the groups. These findings indicate that a balanced diet supplemented with functional AA and polyphenols can help to restore broiler intestinal barrier after a stress exposure.
