Profile and Superovulatory Response of West African Dwarf Does]]>IheukwumereF.C. AbuA.H. OkoliI.C. 3200813The effect of the administration of varying doses of FSH+LH (Pergonal^{®},
Ferring Labs, USA) was used on 16 clinically, sound, parous, West African
dwarf does aged 2-3 years to evaluate the hormonal profiles and superovulatory
responses. Four treatment groups were employed consisting of T_{1}
(administered with physiological saline as the control), T_{2},
T_{3} and T_{4} given 19.0 IU, 58.0 IU and 82.0 IU FSH+LH,
respectively, as intramuscular injections over 3 days. The results on
the number of corpora lutea found on the ovary did not show any significant
difference (p>0.05) between goats on T_{2} (5.25±2.74)
T_{3} (6.25±2.13) and T_{4} (6.50±2.74).
However, they differed significantly (p<0.05) from goats on T_{1}
(3.75±0.30) in the number of corpora lutea on the ovary. The number
of embryos recovered was not significantly different (p>0.05) between
goats on T_{2} (4.50±0.93), T_{3} (4.70±0.86)
and T_{4} (4.75±1.27). However, they differed significantly
(p<0.05) from goats on T_{1} (2.25±0.01) in number of
embryos recovered. Goats treated on T_{2} with embryo recovery
rate (78.30±0.18%) did not differ significantly (p>0.05) from
goats on T_{3} (75.20±0.14%) and T_{4} (73.10±0.06%).
However, they differed significantly (p<0.05) from goats on T_{1}
(60.00±0.02%). The ova/embryo wastage was not significantly different
(p>0.05) between goats on T_{2} (21.70±0.30%), T_{3}
(27.80±0.12%) and T_{4} (26.90±0.16%). However,
they differed significantly (p<0.05) from goats on T_{1} (40.00±0.01%)
in embryo wastage. LH and FSH were highest at T_{3} treatment
group with values of (3.60±0.02 and 3.13±0.14 (IU L^{-1}),
respectively. Progesterone and Oestradiol showed higher values on T_{4}
goats with (16.17±1.01 and 0.26±0.41 nmmol L^{-1}),
respectively. The results of this study indicate that the administration
of FSH+LH enhanced embryo production and hormonal levels in West African
dwarf goats.]]>Akusu, M.O. and G.N. Egbunike,1990Alcivar, A.A., R.R. Maurer and L.L. Anderson,1992Briggadike, H.J., R.A. Laren, A. Collins and R.J. Mansbridge,2000Camillo, H., Vannozi, R. Luzio, S.
