(2007-08) Babalobi, O. O; Olugasa, B. O.; Oluwayelu, D.O.; Ijagbone, I. F.; Ayoade, G. O.; Agbede, S. A.
The mortality losses of pigs of various age groups affected by the 2001 African swine fever outbreak in Ibadan Nigeria were analyzed and evaluated. Thirty one thousand nine hundred and sixteen (31,916) pigs on three hundred and six (306) farms reported by the Pig Farmers Association of Nigeria and the State Ministry of Agriculture and Natural Resources were involved. Gross mortality was ninety one percent (91%), while age group mortality ranged from 75.9% (growers), 83.1% (weaners), 91.2% (finishers) and 99.8% (piglets); to 100.0% in gilts, sow and boars. Losses were estimated to worth nine hundred and forty one thousand, four hundred and ninety one dollars, sixty seven cents (US $941,491.67). Highest financial loss was from sows (29.5% of total loss), followed by gilts (16.6%), finishers (15.2%), weaners (10.7%), boars (10.6%), growers (10.6%) and piglets (8.2%). Average mortality loss per farm of $3076.77 was of great financial and socioeconomic consequences for a developing country like Nigeria with a low Gross Domestic Product figures. In conclusion, the need to immediately revisit and take recommended actions on the 1998 Report of the FAO Consultancy Mission to Nigeria on Control and Eradication of an Outbreak of African swine fever in Western Nigeria is stressed

Hormonal and haematological responses of Clarias gariepinus (Burchell 1822) to nitrite toxicity
(Medwell Journals, 2007) Ajani, F.; Olukunle, O. A.; Agbede, S. A.
Study on hormonal and haematological responses of Clarias gariepinus to nitrite toxicity was carried out to know the magnitude of the effects of this stressor on fish physiology. Haematological responses of C. gariepinus to sub-lethal levels of nitrite (0.1 g L-1) at different exposure h (0, 6, 24, 48, 72 and 96 h) were carried out. Blood samples of C. gariepinus were collected at each exposure h and evaluated for primary and secondary stress indicators. Data obtained were subjected to simple descriptive analysis, analysis of variance and Pearson Product Moment correlation analysis. When exposed to nitrite, there was progressive increase in plasma cortisol level of C. gariepinus from 0 h (101.00± 0.10 ng dL-1) to 48 h (161.00± 1.20 ng dL-1), this later decreased at 72 h (107.00±1.60 ng dL-1), it increased in 96 h to 136.00±1.00 ng dL-1. PCV and Hb were elevated after 6 h of exposure and decreased significantly (p<0.05) at 48, 72 and 96 h of exposure in fish exposed to sub-lethal level of nitrite. From the value of 3.69±0.01 106/l recorded at 0 h, RBC level decreased significantly (p<0.05) at 6 h, this was followed by significant increase (p<0.05) at 24 h. The RBC value later decreased gradually to 2.20±0.56 106 L-1 at 96 h. The study shows that hormonal and haematology balances of C. gariepinus was affected on short term exposure to nitrite toxicity.
