Out of a total of 23,813 poultry cases, 18,304 (76.9%) and 5,509 (23.1%) cases were recorded at the State Veterinary Clinic (SVC) Maiduguri and Veterinary Teaching Hospital (VTH) University of Maiduguri respectively. Out of the 18,304 cases presented at the SVC, viral diseases constituted about 44%, bacterial infections were 19.7%, parasitic infestations were 28.7% while non-infectious conditions were 8.7%. Similarly, out of the 5,509 cases recorded at the VTH University of Maiduguri, viral diseases were 69.9%, bacterial diseases were 10.7%, while parasitic and non-infectious conditions were 15.4% and 4.5% respectively. Among the viral diseases encountered, Newcastle disease (ND) and infectious bursal disease (IBD) were the most important while fowl cholera and coccidiosis formed the major bacterial and parasitic diseases respectively. A successful development of control and preventive measures can only be achieved after a careful assessment of each condition is carried out. \u0000Key Words: Poultry health problems, semi-arid, retrospective study, Nigeria. \u0000Trop.

Twelve healthy sexually mature WAD bucks were used for this study. The animals were starved for 24, 48 and 72 hours and semen samples were collected after each stage of starvation. \u0000It was observed that as the length of starvation increased sperm abnormalities increased and volume of semen decreased. There was no semen production after 72 hours of starvation from any of the bucks. \u0000Secondary types of abnormalities were the common types of abnormalities observed during this study. Their values increased from 7.06% at control to 80.39% and 85.43% at 24 hours and 48 hours of starvation respectively. \u0000Scrotal circumference decreased from 15.75+0.25cm at control to 14.88+0.09cm, 12.95+0.38cm and 12.35+0.40cm at 24hours, 48hours and 72hours of starvation, respectively, due to degeneration caused by starvation. It can be concluded that starvation has adverse effect on the reproductive performances of bucks to be used for breeding programme. Bucks should therefore be well fed before being used for breeding. \u0000Keywords: Acrosome, breeding, morphology, spermatozoa, starvation \u0000Trop. Vet.

Both nitrate and nitrite were analyzed spectrophotometrically using an automated dual channel continuous flow nitrate-nitrate analyzer as nitrite following cadmium reduction of nitrate to nitrite and diazotization of nitrite with sulphanilamide, and coupling with N-(1-naphythyl) ethylenediamine. Secondary amines detected in the forage were diethylamine, dimethylamine, methylbenzylamine, piperidine, methylamine, while primary amines found include n-butylamine, ethylamine, methylamine, isopentylamine and propylamine. Total secondary amines were highest in Urena lobeta (92.7 ppm), but lowest in Dichrostachys cinera (5.6 ppm), while total primary amines were also highest in Urena lobeta (94.7ppm) but lowest in Rottboellia exaltata (8.4 ppm). Only trace amounts of nitrite were detectable in some samples. The toxicological relevance of these findings are discussed with respect to potential endogenous formation of hepatotoxic, mutagenic and carcinogenic n-nitroso compounds in animals, and the consequences of this phenomenon on animal health and production.

A total of 94 (18.8%) of the lung tissues examined had lesions (at various stages) suggestive of CBPP, while 137 (27.4%) and 160 (32%) were sero-positive for CFT and cELISA respectively. One hundred and twelve (22.4%) of the cattle were seropositive for both CFT and cELISA, while 25(5.1%) and 48(9.6%) were seropositive for only CFT and cELISA respectively. Five cattle that had lesions suggestive of CBPP were negative by both CFT and cELISA. Meanwhile, no age predisposition was particularly significant to the development of CBPP lesion in this investigation. It is concluded that the use of cELISA along with abattoir survey in the field by training veterinary officers could provide better and more reliable information on the prevalence of CBPP in Nigeria. \u0000Keyword: Contagious bovine pleuropneumonia, abattoir survey, competitive enzyme-linked immunosorbent assay, compliment fixation test, surveillance, Nigeria. \u0000Trop.

The mixture of sperm with complete Freund's adjuvant was used to immunize five mice of the BALB/C strain intraperitoneally on Day O. The sonicated sperm cell immunize the mice the same tourte on Day 14. The mice were immunized with suspension in Incomplete Freund's adjuvant was used to sonicated sperm without adjuvant on Day 21 before they were sacrificed on Day 24. Spleen cells prepared from the mice were fused with myeloma cells (Ag.8.653) by addition of polyethylene glycol (PEG). Two distinct monoclonal antibodies (antihead (H) and anti-tail (T) Mabs) were produced after cloning of the hybridoma cells. There were intermediate forms that are believed to have arisen as a result of incomplete cloning. The Mabs were identified by the use of indirect immunofluorescence method and their specificity confirmed by their non-reaction with cells from some other organs. These Mabs can be used for further work on the mechanisms of sperm antibody effect on swine infertility. It is speculated that the H.

Lawal","doi":"10.4314/TV.V21I2.4481","DOIUrl":"https://doi.org/10.4314/TV.V21I2.4481","url":null,"abstract":"Trypanosomosis is a major recognized factor limiting livestock productivity. Control of the disease has explored the use of drugs, vector and the farming of trypanotolerant livestock in order to enhance productivity. However, there are documented difficulties with each of the methods. These include drug resistance, re-invasion of controlled areas by tsetse flies and the small population of the trypanotolerant cattle population. Hence the search for genes that will confer trypanosome-resistance and enhance productivity is imperative. Attempts to control trypanosomosis using molecular genetic techniques have continued over the years. In this brief review, the advances made towards an understanding of genetics involved in trypanotolerance will be highlighted. So far, the genome involved in the genetics of trypanotolerance in cattle and in mice, known as the quantitative trait loci (QTL), has been identified using microsattelites. Comparative studies of map data between cattle and mice in the principal QTL region of both species have revealed a region of homology of about 300,000 base pairs (bp) between cattle chromosome 7 and mouse chromosome 17 lying within the principal QTL in both species. This finding points to the possibility that the underlying genes in these two QTL could be the same in cattle and mice and may pave the way for the eventual identification of trypanotolerant genes. The identification of the genes would make it possible to use transgenic approaches that would incorporate resistance to trypanosomosis for control design. \u0000Keywords: Genetics, trypanotolerance, cattle \u0000Trop.
