| dc.description.abstract | “Evaluation of the reproductive behavior in two dairy herds in the province
of Chimborazo”
It was made a reproductive behavior diagnosis in the Ranches “San Jorge de
Balcashi” (Riobamba) and “Cubillin Bajo” (Chambo) of Chimborazo Province;
using reproductive registers of the years 2008, 2009 and 2010. It was classified
the dairy herds by reproductive registers of the years 2008, 2009 and 2010 of
each exploitation, for afterwards elaborating templates for its tabulation and data
processing with the aim to make a comparison between them. The information
was analyzed by means of statistical descriptive processes (media, range,
standard deviation, etc.). From the analyzed variables, none presented meaningful
statistic differences. The ranch Cubillin Bajo presented higher numeric values in
relation to the ranch San Jorge de Balcashi in the age to the first estrus
(666,00±68,15 days), age at the first mating (690,94±67,13 days), age at the first
delivery(988,44±68,15 days), weight of the calves to the first delivery (42,78±3,37
kg), the mortality of calves (9,29%), metritis (9,20%), percentage of conception per
service (21,84, 51,72, 83,91, 98,85,and 100% for the five services, respectively),
and percentage of birthrate (95%). On the other hand, the Ranch San Jorge de
Balcashi presented higher numeric values in relation to the Ranch Cubillin Bajo in
the interval between the first estrus and the first mating (30,29±19,18 days), days
of gestation (279,08±6,15 days), open days (164,01±56,66 days), interval between
deliveries (441,12±59,90 days), weight of the calves (41,10±3,53 kg), placenta
retentions (19,23%), percentage of abortions (8,97%), endometritis (7,69%),
pyometra (5,13%), services per conception (2,48) and reproductive efficiency per
herd, San Jorge (-94). Both studied ranches presented higher values to the
considered as ideals since it could realize that in the research exists some
deficiencies both the detection management of heats, reproductive disease
management and post-delivery treatment of problem cows. For all the previous
information, it was recommended effecting frequent gynecological checks, for
detecting diseases adequately and to make the corresponding treatment, as well
as the using of hormonal methods to treat the troubled cows. | |
