Evaluación del rendimiento productivo en bovinos de leche mediante la aplicación del sistema neozelandés en la parroquia San Andrés, cantón Guano

Abstract

At Tagualag and Tuntatacto Communities, San Andrés Parish, from Chimborazo province, the productive development of the milk cattle farms which use the New Zealander productive system was analyzed by using two treatments; (T1: Model Farm “ComunidadTagualag”), (T2: Model Farm “ComunidadTuntatacto”), contrasted to a witness (T0: Farm with Traditional management San Andres). A completely random block design was applied with ten repetitions for each treatment, with an experimental unit size of 1. The experimental results showed significant differences (P < 0.05), in favor of the farms that used the New Zealander system in the variables of initial production of dry matter (4357.60 kg / ha), initial protein (807.03 kg / ha) and final (836.66 kg / ha), initial ethereal extract (98.48 kg / ha) and final (105.89), initial fiber (783.50 kg / ha) and final (834.48 kg / ha), initial calcium (38.35 kg / ha) and final (39.22 kg / ha), phosphorus initial (18.30 kg / ha) and final (14.82 kg / ha), milk production (17.96 l / day), initial total solids (2.59 kg / ha) and final (2.64 kg) kg/ ha). The highest profitability was obtained by Tuntatacto cattle farm, reaching a benefit / cost of 1.11. It is concluded that the New Zealander system improves the productivity of the farms that use it, so it is recommended to spread the benefits of using this type of system to all producers, since even greater profits are obtained. Key words: Productive Development of the Milk - New Zealander productive system - Milk Production.
