Effect of detoxified karanja (Pongamia spp.) cake on testicular architecture and semen production in ram lambs
The protein-rich non-conventional detoxified karanja cake (dKC) can be used in place of conventional protein supplements like soybean meal (SBM), groundnut meal, etc. in livestock feed. The present study was conducted to assess the effect of two levels of dKC by replacing SBM on testicular architect...

The present study was conducted to assess the effect of two levels of dKC by replacing SBM on testicular architecture, semen quality and expressions of mRNAs encoding luteinizing hormone receptor (LHR) and insulin-like growth factor (IGF-I) in testes of ram lambs. Eighteen ram lambs were randomly divided into three groups (n = 6) and fed different levels (%) of karanja cake (0% replacement – control; 50% replacement – dKC-50 and 75% replacement – dKC-75) for 140 days. After 120 days of feeding, the semen from the animals was collected and analysed. The testes samples were collected on day 140 of feeding for transcripts expression studies. The dKC-50 group had no change in BW, whereas dKC-75 group showed decreased (P < 0.05) BW as compared with control. The number of animals ejaculated semen in dKC-75 group was lower (P < 0.05) than the control group. A reduction (P < 0.05) in LHR expression in dKC-75 was observed, whereas a reduction in IGF-I expression (P < 0.05) was observed in dKC-50 and dKC-75 as compared with control group. The study reveals that in ram lambs, long-term feeding of dKC at 50% replacement of SBM may not affect BW. However, long-term feeding of dKC as a replacement of SBM may affect testicular function.http://www.sciencedirect.com/science/article/pii/S1751731113001316karanja cakeram lambssemen qualityIGF-ILHR |
