| Summary: | In Colombia, the department of Nariño has approximately 102,511 cows with a milk
production of 982,924 liters per day, which contributes greatly to the dairy
productivity of the region. The municipality of Aldana has a production of 35,898 liters
with a number of cows in production of 2,864, in this area the Holstein, Jersey and
Norman breeds predominate.
Among the factors that alter the reproductive parameters are diseases that can be
congenital, infectious, parasitic, nutritional and / or metabolic causing economic
losses in livestock farms, increasing the interval between births, number of days
open, percentage of empty cows, percentage of mortality and decrease services by
conception, age at first service, percentage of pregnant cows and birth rate.
One of the biggest concerns in the livestock sector of the municipality of Aldana, is
the lack of evaluation of reproductive parameters and factors that determine the
performance and efficiency in the herds. Most of these farms do not have an
adequate management of these.
The study population will be carried out in 92 cattle between the Holstein, Jersey
and Norman breed in three dairy farms in the municipality of Aldana. The records
kept by each farm will be compiled to be able to make a general description and then
evaluate the reproductive status of both female and male animals.
The nutritional status of each of the farms will be reviewed, as it is one of the main
factors involved in the success of reproduction. This will be done by determining the
weight of the animal, age and its physiological state (pregnant or empty). Through
the quantity and quality of forage supply available on the farm. |
