Reproductive Performance of Rabbit Does and Productivity of their Kits in Response to Colour of Light
Z.M. Kalaba and A.E. Abdel-Khalek

Abstract:
The information in the literature on the effect of light colour on productive and reproductive performances of rabbit production is scare. It was suggested that evaluation of the light colour’s effect on the rabbit production can be perspective. This study aimed to evaluate the effect of florescent (FL) and red (RL) compared with Natural Light (NL) on reproductive performance of rabbit does and growth performance of their kits. Total of 75 mature California does were divided into three groups (25 in 5 replicates for each) in separated rooms. Control does were exposed to natural day light (G1), while those in G2 and G3 were exposed to artificial fluorescent or red lights, respectively for 16L/8D regime. Kindling Rate (KR), Gestation Period (GP) and Litter Size (LS) of does as well as weight (LW), Viability Rate (VR) and gain of kits was recorded at birth and weaning for three consecutive litters. Blood samples were collected pre-insemination for the 2nd parity from 10 does in each group for determination of melatonin, FSH and oestrogen concentration in plasma. Values of KL, reproductive index of does, LS, VR and LW of kits at birth and LS, VR, weight and gain of kits at weaning were the highest (p<0.05) and GP was the shortest (p<0.05) for RL does. Artificial lights (FL and RL) increased (p<0.05) melatonin, FSH and oestrogen concentrations. In conclusion, using industrial red light resulted in increasing reproductive performance of rabbit does and weight and viability of their kits.
