Blood metabolites and hormones of v-line and bauscat female rabbits under middle Egypt conditions.
Abstract: A total number of 20 does V-line (exotic synthetic line, VL) and 28 does Bauscat (exotic breed, B) rabbits were used. Also, sixteen bucks for mating only were used. The present study aimed to throw some lights on blood constituents and does performance during different periods of pregnancy in V-Line and Bauscat rabbit does under Middle Egypt conditions during October-March period.
The results showed that breed had no significant effect on albumin (Alb), globulin (Glb), Alb/Glb ratio, aspartate aminotransferase (AST), and alanine amin(}transferase (ALT).
However, V-Line does showed significantly (P<0.05) the highest values of total protein (TP) and total lipids (TL), while Bauscat realized significantly (P<0.05) the highest values of alkaline phosphatase. The levels of TP, Alb, Glb and alkaline phosphatase enzyme reached theirpeak values at day 14 of gestation.
The V-line exceeded Bauscat does in triiodothyronine (T3) and progesterone (P 4) concentrations without significant differences, while estradiol (E2) level was significantly (P<0.05) higher in the pregnant Bauscat does than V-line ones. Pregnancy stage effected significantly on T3, P 4 and E2 concentrations.
Number of services per conception decreased in V-line does as compared with Bauscat does. The decrease in number of services per conception was associated with high value of conception rate.
Number of parities per does slight decreased in V-line does compared to Bauscat ones. Also, V-line does exceeded Bauscat ones in litter size at birth and at weaning, and litter weight at birth and at weaning.
Keywords: Rabbits, blood metabolites, hormones, V -Line, Bauscat.
