Comparative Study on the Use of Artificial Insemination in Sows in Three Production Units in the Region of Tlachichuca Puebla, México

Abstract

The main objective of this study was to make a comparison of the use of artificial insemination in sows from three production units belonging to the Tlachichuca-Puebla region, Mexico. These pork production units belonged to the communities of José María Morelos, San Francisco Independencia and Tlachichuca, Puebla respectively. 20 sows were used, 15 of which were primal and 5 multiparous, which were inseminated over a period of 10 months. 20 doses of semen were acquired from the Coyametl Genetic Transfer Center, located in the City of Acatzingo, Puebla. The information obtained from the project was concentrated in the different stages of the study, and stored in an Excel file; the information was processed through the SPSS 10 package for Windows, applying descriptive statistics. 75% of Primal or Nulliparous sows were found which were artificially inseminated and 25% corresponded to Multiparous; 7% of the producers expressed no interest in planning but rather a greater number of kilos when selling, 15% responded interest in the number of offspring and fewer deaths at birth with better feeding of the bellies before and after the births, 78% mentioned the importance of planning a procedure to improve their productivity and reproductive life in their pork production units (PPUs). Regarding litter size, results were obtained through AI in the sows of the 3 UPPs (José María Morelos, San Francisco Independencia and Tlachichuca), a total of piglets in the primals of 163 of the 15 inseminated sows, with an average of 10.8 piglets/sow; In the case of multiparous sows, there were 58 piglets in total with an average of 11.6 piglets/sow. In conclusion, comparative studies are useful for analysis in pork production units, since they are pillars in decision making; as it was, in the reproductive indicators where AI was applied, giving objectivity and greater certainty as was the case in the three communities of the Tlachichuca region, Puebla, Mexico.
