  The difference in Erythrocyte Osmotic Fragility (EOF) and haematologic parameters among two pure (Marshal and Ross) and a Hubbard-Anak cross breeds of 9-week-old broiler chickens were evaluated in this study. There was a statistically significant (P<0.05) decrease in EOF in Marshall breed at NaCl concentrations of 0.5% when compared to other breeds. However, Ross breed had the highest EOF at this NaCl concentration. Haematologic parameters of Packed Cell Volume (PCV), haemoglobin concentration, Red Blood Cell (RBC) count, erythrocytic indices and differential leucocyte counts were not significantly different (P>0.05) among the three breeds. In conclusion, this result revealed a breed difference in EOF and that erythrocyte membranes are osmotically more stable in Marshal breed of broiler chickens.

  The aim of this study was to evaluate the features of induced abortion and post-abortion oestrous cycles pattern following treatment with prostaglandin F (PGF) in Sokoto Red (SR) goats. Twelve apparently healthy goats made up of 6 pregnant and 6 non-pregnant (cycling) does were used for the study. Each doe was given a single intramuscular injection of 7.5 mg PGF. All the 6 pregnant does treated with PGF aborted within 72.0±12.4 h post-treatment. Of the 6 does that aborted, 5 (83.3%) showed oestrus subsequently while 4 (66.7%) out of the 6 non-pregnant does were induced to oestrus. Time interval to induced oestrus was 129.6±36.1 and 50.0±11.5 h for the aborted and non-pregnant does, respectively. Mean duration of oestrus for the aborted and non-pregnant does was 46.9±9.6 and 38.7±4.3 h, respectively. The first and second post-abortion oestrous cycle lengths were 6.5±0.5 and 12.5±8.5 days, respectively. While the first and second post-treatment cycle lengths in the non-pregnant does was 22.5±1.2 and 21.3±0.3 days, respectively. It is concluded that a single dose of 7.5 mg PGF is sufficient to induce abortion and oestrus simultaneously in SR goats. However, the post-abortion cycles are short.

  A 1 1/2 years old apparently healthy Sokoto Red (SR) goat weighing 16 kg was diagnosed with bilateral Cystic Ovarian Follicles (COF) at postmortem carried out 24 h from the onset of standing heat. No follicles or recent copora lutea were visible on the ovaries. The weights of right and left ovaries with their cysts were 32 and 15 g, respectively. The lengths of the right (ROC) and left (LOC) ovarian cysts were 18 and 15 cm, respectively. The circumference of the bulbous ovarian end and the posterior tail-like extensions of the cysts were 12 vs. 2.5 and 6 vs. 2 cm, respectively for the ROC and LOC. The volume of follicular fluid contained in the ROC and LOC were 25 and 9.5 mL, respectively. It was concluded that the ROC had larger weight and dimensions than the LOC.
