				Abstract 
 
              Aim: 
              This study was 
              conducted to understand whether serum level of the steroid and 
              metabolic hormones may be indicative of their level in ovarian 
              follicular fluid (FF) in porcine, and its influence on fertility.
               
              Materials and 
              Methods: 
              Ovaries from pigs 
              (n=32) of two genetic groups, namely, native (Ghungroo; n=16) and 
              crossbred (Hampshire × Ghungroo; n=16) were collected. Both the 
              genetic groups comprised gilts (n=8) and sows (n=8), and sows were 
              in luteal phase of estrus cycle. FF was aspirated from small, 
              medium and large follicles, and centrifuged for the collection of 
              supernatant for further analysis. Blood samples were collected 
              from the same animals, and serum was separated. Hormones, namely, 
              cortisol, T3, T4 and testosterone were estimated by 
              radioimmunoassay. Two-way ANOVA was used for analysis of data 
              considering genetic background (native or crossbred), stage of 
              reproductive life (gilt or sow), and source of sample (serum or 
              FF) as fixed effects.  
              Results: 
              It was 
              observed that all the hormones except cortisol differed 
              significantly (p<0.01) based on genetic background. Stage of 
              reproductive life and source of sample did not affect the studied 
              hormonal level. Within the genetic groups, stage of reproductive 
              life influenced T3 (p<0.01), cortisol (p<0.05) and testosterone 
              (p<0.01) level in crossbred pigs as compared to T3 (p<0.01) only 
              in native pigs. The level of T3 in serum, as well as FF, was 
              higher (p<0.01) in Ghungroo gilts compared to sows. However, a 
              reverse of this was observed in the case of crossbred pigs. The 
              level of cortisol (p<0.05) and testosterone (p<0.01) was higher in 
              crossbred sows than gilts in both serum and FF.  
              Conclusion:
              The 
              study revealed that serum level of the steroid and metabolic 
              hormones is indicative of their level in the ovarian FF. Further, 
              varying level of steroid and metabolic hormones in pigs based on 
              genetic background may be due to variation in body size, rate of 
              energy metabolism and stage of (re)productive life.
