Samar Raafat Farouk Mohamed: Effect of Some Enzymes and Medicinal Plants on Fertility in Different Rabbit Breeds. Unpublished M. Sc. Thesis, Department of Animal Production, Faculty of Agriculture, Ain Shams University, 2011
The present experiment was carried out at Intensive Rabbit Production Unit, belonging to Consulting and Research Center, Faculty of Agriculture, Ain Shams University. This experiment designed to study effect of some enzymes and medicinal plants on fertility in NZW rabbits. A total number of 24 mature New-Zealand White (NZW) rabbit bucks (aged 6 months) were used in the present study. Animals were divided into four comparable experimental groups (6 males each). The first group was fed a commercial diet and kept untreated (control group), while the 2nd; 3rd and 4th groups (treated groups) were fed the same diet but supplemented with ZAD; Arak extract and ZAD with Arak extract (2 cm/ L) given in water), respectively. Unreceptive female was used as teaser for semen collection purpose. Semen was collected twice weekly and evaluated, after that, good ejaculates from bucks of each group were pooled together and diluted by adding one part semen to five parts extender at 37°C. During maturity fertilizing ability of bucks was studied as affected by ZAD and/ or Arak (SalvadoraPersica) in drinking water. Physical semen characteristics and testosterone were recorded. Females were used for fertility test (conception rate and litter size were recorded). Present experiment showed a higher rate of growth and sexual desire (sec) in treated than control. Mass motility and advanced sperm motility increased (P≤0.05) in males treated with ZAD and/ or Arak. The average percentages of dead spermatozoa, sperm abnormalities were decreased by adding ZAD and/ or Arak to drinking water.The improvement in body growth and male reproductive parameters combined with elevated blood testosterone level was indicated by fertilizing ability of bucks and fertility traits of does which were significant (P≤0.05) and arranged in descending order as (ZAD and Arak); ZAD then Arak group, respectively as compared to the control group.It could be concluded that, rabbit reproductive performance was improved by supplementing ZAD and/ or Arak to drinking water and the better results were obtained in the 4th group which received combined treatment of ZAD and Arak. Treatment with Arak may enhance and promote the physiological effects of ZAD on body growth and reproductive performance in rabbit bucks.
