The present study was carried out to characterise and quantify the level of fertility by analysis the effect of breed on testicular parameters stallions (Arabian versus Barb). Testicles were measured with a calliper total scrotal width (TSW), the left and the right testicular width (LTW, RTW), the left and the right testicular length (LTL, RTL) and the left and the right testicular height (LTH, RTH) respectively. The experiment was conducted during a period of a year on twelve Arabian stallions (n=144) and six Barbian stallions (n=72) clinically healthy raised in National Haras Chaouchoua of Tiaret, Algeria. From these measurements, the total testicular volume (TTV), testicular parenchyma weight (TPW) the testicular weigh (TW), the daily sperm output (DSO) and the daily sperm product (DSP) were calculated. Results obtained were tabulated and statistical analysis was performed using the statistical package SPSS 20.0 (SPSS Inc., Chicago, IL). The breed and the season effect was performed by using One-way ANOVA analysis. The level of significance was set at P<0.05. There was highly significant difference (p<0.01) in the DSP between breeds (4.12±1.16 versus 4.56±1.12) respectively in Arabian and Barb stallions. There was a significant influence of breed (p<0.05) on some testicular parameters such (TTV, TW, TSW, TPW and DSO). Our study allowed us to better understand the distinction between Arabian and barbed stallions by the size of their testicles and their sperm production. The Barb stallions have higher testicular parameters compared to the Arabian stallions caused by genetic effect.
