- Abstract
The use of artificial insemination (AI) in cattle provides greater efficiency in breeding and increased gains in animal production programs. In this regard, the inseminator has an important role, where his performance in conducting the IA technique can influence the results. The present study aimed to evaluate the technique of artificial insemination between two herdsman-inseminators. The experiment was conducted on a property located in the municipality of Pedro Gomes, State of Mato Grosso do Sul. Technique of herdsman-inseminators (A and B) was evaluated in a herd of 206 female cattle able of reproduction, the Trimberger method being used for AI for a period of 38 days. The semen used was evaluated by the soundness examination before breeding season. All procedures related to animal handling and AI technique prior to insemination were standardized. Pregnancy diagnosis was performed by rectal palpation 60 days after the last animal insemination. There was a statistically significant difference between the inseminating, (p = 0.0017), and the most successful herdsman-inseminator A obtained after performing 172 procedures IA with results of 146 (84.9%) pregnant cows, while the herdsmaninseminator B inseminations performed 34 and obtained 21 (61.8%) pregnant cows. The herdsman-inseminator A has 3.47 times more likely to be successful in the insemination technique herdsman-inseminator B. It is concluded that there was a better use of the technique of artificial insemination by the herdsman-inseminator A, obtaining the highest conception rate in relation to the herdsman-inseminator B.
