Evaluation of Boar’s Semen Production and Characteristics for Artificial Insemination

The objective of this work was to evaluate the production and characteristics of boar semen from different genetic lines used for artificial insemination, for which 19 boars were used: LM100 (n=4); LM200 (n=2); LM300 (n=2); LTP27 (n=4); LTH1 (n=2); LTB1 (n=3) and LTB37 (n=2) for two and a half years; the variables evaluated were Ejaculate Volume, Motility %, Temperature, Sperm Concentration, Collection frequency, Season of the year, Age and Number of doses. The general averages of the results obtained were: semen volume 263.64 ± 3.59, Motility 89.99 ± 0.20, Ejaculate temperature 37.12 ± 0.03, Dose x ejaculate 19.43 ± 0.36, Winter season, semen volume 263.69 ± 3.59, Spring Motility 90.81 ± 0.43, Autumn temperature of the Ejaculate 37.12 ± 2.74, Spring number of doses (300 x 109) ; 19.43 ± .35, in relation to the Genetic Lines in which there was a significant difference with respect to the evaluated variables were in Volume it was LTP-27 with 328.74 ± 7.97 mL (P <0.05), in % Motility it was LTH-1, 91.81 ± 0.52 (P<0.05), in Ejaculate Temperature The LTB-1 with 37.70 ± .09 (P>0.05), in dose was the LTP-27, 23.15 ± 0.64 (P<0.05), the behavior by season of the year and your variables.
