Diferentes protocolos de dosificación de vitaminas y aminoácidos en gallinas de la línea Lohmann brown en la granja avícola Dos Hermanos en el cantón Chambo.

Abstract

At the “Dos Hermanos” farm, located in Chambo Town, Chimborazo Province, the effect of different degenerative doses of vitamins and amino acids applied food for posture poultry was evaluated. For this investigation 480 Lohmann Brown-line hens during the first production phase of 32-42 weeks of age were used with 4 repetitions per treatment, distributed under a Completely Random Design (CRD). For the separation of media, the Tukey test was used. The best productive results were obtained with the use of Protocol 3 (43g of Mayvit) (6 days a week for 2 times in 6 weeks) with a laying percentage of 91.85%; production percentage / bird / day of 92.02%; percentage of production / bird / housed of 90.60%; egg production / bird / day of 53.25 eggs / bird; egg production / bird / housed of 52.81 eggs / bird; weight of the eggs produced 64.97g; mass of eggs produced 59.68 g. The best percentage of uniformity of the eggs was obtained with the use of Protocol 2 (29g of Mayvit), (4 days a week for 3 times in 6 weeks) applied to the food, achieving a percentage of 92.4% and low mortality rates. The feed conversion was statistically influenced and achieved the best results with Protocol 3 of vitamins and amino acids with a feed conversion of 1.34. The highest profitability was obtained with the use of Protocol 3, reaching a benefit / cost of 1.20. Therefore, it is recommended to use Protocol 3 of vitamins and amino acids applied in the feed since the best productive parameters were obtained in addition to obtaining the best benefit / cost in feeding in laying birds.
