The experiment was conducted in a swine production commercial enterprise, using the semen of 29 boars ages between 10 months and 5 years, from a commercial line. The aim of the study was to evaluate the effect of adding 1% L-glutamine L-glutamic acid in the diet on boars fresh semen quality. The animals were divided into blocks in a completely randomized design, with two treatments, T1− standard farm diet (RP) and T2- standard farm diet + 1% L-glutamine L-glutamic acid (RP+LGln-LGlu). Diets were fed in mash form, formulated to meet the recommendations for boars. The seminal variables were: volume of semen, concentration, motility, force and morphology, and percentage of lives and dead sperm cells, and testes volume. The means for semen volume and sperm cells motility, were 255. 32±6.5 and 290.57±9.1; 87.72±0.2 and 89.89±0.01 respectively for T1 (RP) and T2 (RP±LGln-LGlu) treatments. The 1% L-glutamine L-glutamic acid add in the diet influenced semen volume and sperm cells motility (P 0.05). The mean for T1 (RP) and T2 (RP±LGln-LGlu) treatments were: sperm concentration (79.01±2.5 and 77.53±2.7), force (3.99±0.01 and 3.99±0.01), morphology (normal cells 90.1±0,4 and 88.59±0.6), live spermatozoa (92.43±1.8 and 93.23±2.5), dead sperm cells (7.56±0.2 and 6.84±0.2) and testicular volume (right: 668.06±32 and 739.27±31, left: 793.40±36 and 777.22±39) and were not affected by treatments (P>0.05). No interaction have been detected between treatment and age. The addition of 1% L-glutamine L-glutamic acid, on boars diet increased the fresh semen volume and sperm cells motility.
