Two hundred and forty Japanese quail aged 125 days were randomly allocated to five treatment groups based on laying (%) and quail's weight (90.71 ± 1.8% egg/day × 100 and 178.05 ± 9.38 g, respectively), each of which included six replicates of eight quails. The diets were formulated based on corn, soybean meal, and industrial amino acids. An optimal diet achieves 100% of amino acids required by the quail requirements, except for threonine. Five treatments were made: 20% less amino acid; 10% less amino acid; optimal diet; 10% more amino acid; and 20% more amino acids than those in the optimal diet. The increase in amino acid levels in a fixed Lys: amino acid ratio led to histological alterations in the liver and uterine epithelium, reduction in blood lipid peroxidation, lower hepatic HSP70 gene expression, and the performance of laying Japanese quail. The optimal diet based on the NRC with an adjusted Thr: Lys 78 ratio (Lys 1.0%) improved the performance and efficiency of Japanese quail from 125 to 230 days of age.
Resumo: O objetivo foi avaliar codornas europeias, alimentadas com rações à base de milho+soja e trigo+soja, associadas com suplementação de xilanase e fitase. O estudo foi executado no período de 20 de agosto a 02 de outubro de 2019, aprovado sob protocolo N° 038/18 pela Comissão de Ética no Uso de Animais -CEUA da UESC. Um total de 224 aves aos 7 dias de idade foram alojadas em gaiolas modo baterias, com comedouros do tipo calha e bebedouro copinho, com temperatura ambiente controlada conforme recomendações. As aves foram distribuídas em delineamento inteiramente casualizado (DIC) no esquema fatorial (2x3 + 2), considerando duas bases de aplicação das rações, Milho + Soja e Trigo + Soja, três modos de uso de enzimas (16000BXU / kg de Xilanase; 2000FTU / kg de fitase; e 16000BXU / kg de xilanase + 2000FTU / kg de fitase), mais dois controles, totalizando 8 tratamentos de 7 repetições com 4 aves cada. Foram analisados dados de consumo de ração (CR, g/ave), ganho de peso (GP, g/ave), conversão alimentar (CA, g/g) e peso vivo final (PVF, g/ave). A suplementação da fitase isolada aumentou o CR mas não influenciou o GP nem a CA. A utilização da xilanase promoveu uma melhora benéfica no CR e na CA. Em conclusão, recomenda-se o uso de uma ração formulada à base de trigo e soja, com xilanase, para codornas de corte até os 21 dias de idade.Palavras-chave: Degradação dos fatores antinutricionais, otimização de matriz nutricio.
Were used 724 quails, with initial weight of 105.05±1.40g to determine the model requirements for European quails 16-36 days old. Were used 384 quails for the maintenance requirement experiment and 240 for the gain requirement experiment and the remaining 100 quails composed the birds of the comparative slaughter. Maintenance requirement: the treatments consisted of four levels of feed offerings (100, 75, 50 and 25% of consumption ad libitum) with four pens and four quails per pen for each climatic environment (18, 24 and 28ºC), being 192 quails for each nutrient under study. Gain requirement: the requirements of the studied nutrients for gain were determined from 240 quails, created and fed ad libitum, being 120 quails for each nutrient studied, that is, 30 quails were slaughtered at 21, 26, 31 and 36 days of age. The quails of the reference slaughter comprise the same as the experiment for determining the maintenance requirement. In conclusion. The prediction equations for estimating the requirements were: 1) Pr (mg/quail/day) = (27.029 + 1.5943 × T) × kg0.75 + 12.24 × WG, in which Pr is the phosphorus requirement, kg0.75 is metabolic weight (kg), WG is weight gain (g/quail/day). 2) Ca (mg/quail/day) = (158.93 - 5.187 × T) × kg0.75 + 23.66 × WG, in which Ca is the calcium requirement, kg0.75 is metabolic weight (kg), WG is weight gain (g/quail/day), T is temperature.
The use of betaine associated or not with choline chloride 70% in Japanese quail diets in the laying phase was evaluated. 504 Japanese quails (Coturnix cortunix Japonica) were used from 104 to 208 days old, in a 3x2 + 1 factorial design, completely randomized design, seven treatments, nine replications, eight birds per experimental unit. Betaine was supplemented in 20% of the digestible methionine level of the control diet, in diets with reformulated betaine the level of enrichment was in the nutritional matrix of the product (100%) and with an extra recovery of 5% (105%). Choline chloride was fixed at 0.07%. Productive performance, egg quality, histometry, and the number of goblet cells from the duodenum and hepatic glycogen were analyzed. The use of betaine promoted greater weight of the eggs to the control, regardless of the mode of use, the use of choline promoted a superior result in the weight of the eggs. In egg quality, only shell percentage was influenced. The use of the reformulated betaine 100% of the matrix promoted greater height of the villi, and a lower villus: crypt ratio to the treatment with the reformulation enriched by 105%. Hepatic glycogen was not influenced. In goblet cells, the reformulation in an extra 105% of the matrix was superior to the matrix in 100%. The hill reduced villus height, improved villus: crypt ratio, and number of goblet cells. In conclusion, the reformulated betaine enriched in an additional 5% of its nutritional matrix replaces the use of choline chloride in the laying of Japanese quail diets.
