Abstract
In order to evaluate an artificial insemination programme and reproductive efficiency of dairy herds in Uruguay, a survey was conducted with five dairy farms, utilizing a total of 768 lactating Holstein cows. Precision of oestrous detection was assessed by one milk progesterone sample taken on day of breeding and was 11.1%. Two additional samples taken at day 10 and 23 were used to confirm ovulation and early pregnancy. Accuracy of pregnancy estimation by milk progesterone was 70.4%. Reproductive efficiency was determined by the analysis of records. Average intervals from calving to first service were 101 days and to conception 132 days and these were affected by parity, body weight and body condition at calving, but not at breeding, or by milk production. Oestrous detection rates and pregnancy rates were 37.5 and 15.6%, respectively. It was concluded that losses in reproductive efficiency in dairy farms of Uruguay in a seasonal artificial insemination programme were mainly due to unobserved heats, rather than incorrect oestrous detection. |

Contenido : |
Breeding sheep for increased feed efficiency (FE) and decreased methane emissions (ME) is an alternative for developing more sustainable sheep production systems. With the aim of generating genetic and genomic tools, we added in 2018 the evaluation of FE and greenhouse gases emissions to the usual phenotyping as part of the national genetic evaluation per breed, for wool, meat, growth, health and reproduction traits. This initiative provides the information to characterize FE and ME and estimate genetic parameters for Uruguayan sheep. |
