Reproductive Response Of Rabbits Fed Supplemental Moringa Oleifera (Lam) Leaf Meal

ABSTRACT

Reproductive inefficiency is a major challenge in rabbit production. Leaf meals such as

Moringa oleifera rich in phytochemicals have been used to enhance reproductive

performance in cattle and catfish. Information on the use of Moringa oleifera Leaf Meal

(MoLM) to enhance reproductive efficiency in rabbits and its effect on organs has not

been adequately documented. Therefore, the reproductive response of rabbits to

supplemental MoLM was assessed.

In a 24-week trial, sixty rabbits were allotted to four diets containing supplemental

MoLM : 0 (control), 2.5, 5.0 and 7.5 % with 10 does and 5 bucks per treatment. Dry

Matter Intake (DMI, g) and Daily Weight Gain (DWG, g) were determined. Blood (5.0

mL) was sampled from bucks and does for Haematology (Erythrocytes, x103mm-3,

Packed Cell Volume (PCV, %), haemoglobin, g/100 ml), Alanine amino Transferase

(ALT, IU/L) and hormonal (testosterone, oestrogen) assay using standard procedures.

Bucks were assessed for semen characteristics and then assigned to does on each

treatment at 2 does/buck for mating trial using standard procedures. Blood (3 mL) was

sampled from pregnant does at third trimester for progesterone determination using

standard procedures. Conception Rate (CR), Gestation Length (GL), Litter Size (LS) and

Litter Weight (LW) were determined using standard procedures. Testes and epididymides

were removed, weighed and processed for sperm reserves (x106 sperm cells/ml).

Histopathology (no visible lesion, mild, moderate, severe and very severe) of liver,

kidney and ileum was assessed using standard procedures. Data were analysed using

descriptive statistics, polynomial regression and ANOVA at α0.05.

The DMI was not significantly different among the treatments. The DWG of rabbits on

control (6.3±0.8), 2.5% (5.2±0.4) and 5.0% (5.2±0.5) MoLM were higher than those fed

7.5% (4.4±0.4). Erythrocytes (6.8±0.2), PCV (40.2±1.6) and Hb (13.0±0.5) were higher

in rabbits fed 2.5% MoLM. The ALT of rabbits on control (19.2±2.0) was significantly

lower than those on MoLM diets (38.7±4.2 – 48.2±2.7). Oestrogen values ranged from

16.5±1.2 to 25.8±2.0 ng/L and was higher in rabbits fed MoLM than those on control

(10.0±0.8ng/L). Progesterone levels were higher in rabbits on MoLM diets ranging from

1.8±0.4 to 2.8±0.4 ng/L than those on the control (0.63±0.1ng/L). Serum testosterone

level was not significantly different among the treatments. Sperm motility (90.3±0.2%),

mass activity (3.0±0.01), live sperm cells (88.5±3.4%) and CR (100.0%) of rabbits fed

2.5% MoLM were higher than those rabbits on other treatments. The GL, LS, and LW

were not significantly different among the treatments. Testicular sperm reserves ranged

from 14.0±1.5 to 53.0±11.1, while epididymal sperm reserves were not significantly

different among the treatments. Histopathology of liver, kidney and ileum indicated

moderate necrotic lesions at 5.0 and 7.5 % MoLM. Regression of sperm motility on

MoLM levels in bucks indicated an optimum inclusion level of 2.7% (R2=0.56) while

regression of conception rate on MoLM levels in does showed an optimum inclusion

level of 2.5% (R2=0.61).

Moringa oleifera leaf meal at 2.5% inclusion in the diet of rabbits enhanced growth,

semen quality and fertility rate without adverse effect on blood profile.
