Agregar Etiqueta | Sumario: | The production of small dairy farmers in the province of Cotopaxi is unsustainable due in part to the lack of records kept by them, which leads to unsustainability and compromises food insecurity. Therefore, the project of sustainable genetic improvement in dairy cattle was implemented in the city of Salcedo in the parish of Mulliquindil de Santa Ana, to determine the profitability of each of the producers, estimate economic and genetic values, and therefore the response to the selection, such that are in the objectives of the project. First, all animals (127) belonging to 30 members were dewormed, vitaminized, and vaccinated with Cattlemaster Gold fp 5. The aim was to keep them free of parasitic infections, prevent viral diseases, and improve milk production. Subsequently, production data and reproduction records were collected for statistical analysis to establish the selection criteria based on profitability, using BLUP to estimate the genetic value. The results show that the cost of production is 39 ctvs for the production of 1 liter of milk and the monthly profit is $31.32 per producer. The highest percentages of the costs are 25% ($835) in veterinary services and in feed with a value of 19% (622.15), consequently, the criteria to consider are: Days of lactation (305), milk density, Milk in kg, Daily Weight Gain (GDP). Genetic value in GDP gave a result of 228.96 g/day and density 0.268 g/ml. Finally, the response to selection, in general, is low since the average of the current phenotype for density is 1,026 g/ml and GDP 258 g/day, therefore it is established that for GDP through selection with the Lulu cow, we would reach the optimum in two generations and in density with the Martina cow in 1 generation. |
