Abstract

Twenty eight crossbred rabbit does were fed levels of concentrate and lablab hay combinations during pregnancy and at lactation in a completely randomized design to examine the partitioning of protein by breeding does. During pregnancy, 150 g/day/doe concentrate and lablab hay combinations (20:130g, 40:110g, 80:70g and 100:50g) of feed was offered while 350 g/day/doe concentrate and lablab hay combinations (47:303g, 94:256g, 188:166g and 276:74g) was also offered during lactation. Data collected for live weight (LW), dry matter (DM), digestible crude protein (DCP) intake and litter weight were used to estimate metabolic weight, protein requirement for maintenance, fetal growth and lactation of rabbit does. Results obtained showed pregnant rabbit does fed the combinations had significant (P<0.05) differences in the parameters considered apart for LW, DM intake DCPmaintenance and DCPrequirement. During the lactating phase, most parameters considered showed no significant (P>0.05) difference although DM intake (147.96 to 202.04g/day) and balanced DCP (-3.29 to -2.19g/day) which had significant (P<0.05) difference. At the stages of pregnancy, the 4th week had significant (P<0.05) difference over the 2nd week in most parameters apart for LW, DCPmaintenance (7.52 to 7.57g/day) and DCPrequirement (2.04 to 2.05g/LW0.75/d) that had no significant (P>0.05) differences. The diet combinations were adequate to meet protein requirement of pregnant rabbit does but not adequate for lactating does as observed in the balance DCP for the lactating does. Hence there is the need for the investigation of suitable combinations of concentrate and forage for lactating rabbit does to avoid any adverse effects in subsequent reproductive circles.
