The relationship among nutritional status, systemic insulin-like growth factor-I (IGF-I) and ovarian function early postpartum were investigated. A total of 27 Holstein-Friesian cows, 10 that cycled normally within 20 days postpartum, 5 diagnosed with follicular cysts, 8 persistent corpus luteum (CL) after the first ovulation 4 inactive ovaries used for study. Blood samples collected 1-3 times per week, 60 pre- IGF-I, progesterone, estradiol, free fatty acids (FFA), blood urea nitrogen...
A study was performed in 2008 to estimate the prevalence of tuberculosis and brucellosis traditionally reared cattle Southern Province Zambia four districts. The single comparative intradermal tuberculin test (SCITT) used identify TB reactors, Rose Bengal (RBT), followed by confirmation with competitive enzyme-linked immunosorbent assay (c-ELISA), for brucellosis. total 459 animals were tested 395 overall BTB based on 4 mm 3 cutoff criteria 4.8% (95% CI: 2.6–7.0%) 6.3% 3.8–8.8%),...
We investigated the therapeutic effects of a progesterone releasing intravaginal device (PRID) on cystic ovarian disease (COD) and reproduction performance cows. The possible influence PRID metabolic and/or health status was also examined. A total 40 Holstein-Friesian cattle, with structures, ≥2.5 cm in diameter, persisting for more than 7-14 days, without corpus luteum (CL) were used study. or placebos inserted into vagina 12 days. Five animals lost before removal one culled. Based plasma...
Ethno veterinary knowledge has rarely been recorded, and no or limited effort made to exploit this despite its widespread use in Zambia. This study documented the types of plants used treat important animal diseases rural Zambia as a way initiating their sustained documentation scientific validation.The was done selected districts Southern Zambia, Africa. The research participatory epidemiological conducted two phases. first phase pre-study exploratory rapid appraisal familiarize researchers...
The aim of this study was to evaluate the therapeutic effects and safety progesterone releasing intravaginal device (PRID) in treatment inactive ovaries dairy cattle. possible influence PRID on metabolic and/or health status also examined. A total 30 anestrous Holstein-Friesian cows, which rectal palpation had small, flat smooth or rounded were used for experiment. placebos inserted into vagina left place 12 days. Four animals lost one culled. At time insertion, other 25 divided two groups:...
Production and reproduction records of the Holstein dairy herd at Edinburgh University's Langhill farm were analyzed to study incidence, possible risk factors assess reproductive performance cows with cystic ovaries. Risk investigated whether a cow was from genetically selected or control herd, 305 day milk yield equivalent previous lactation one, age/parity. For analysis consequences ovarian disease, individually matched non-cystic mates for selection age/parity, month calving. The...
The present study was conducted to investigate the distribution of virulence genes and antimicrobial susceptibility Salmonella isolated from dogs chickens. A total 379 samples were examined with 41 isolates being cultured 18 (7.4%; 95% CI: 4.57-11.6) 23 (16.9%; 11.2-24.5) dog chicken, respectively. On serotyping, belonged Group B, C, D E, while 6 untypeable. Polymerase chain reaction (PCR) assay carried out detect invA, invF sipC genes. varying targeted observed amongst isolates. InvA found...
<title>Abstract</title> This study aimed to characterize the Angoni breed of cattle sampled from three provinces Zambia determine existing genetic variation. Information owners through group discussions and secondary data livestock extension officers was used sample animals for this study, while sites were selected using population distribution Statistics Agency. Morphometric measurements phenotypic characteristics measured recorded each animal. The age animal estimated teeth dentition. Data...

Ultrasonographic examination was carried out in a cow wiyh an ovarian abscess. Real time ultrasound scanning using 7.5 MHz linear probe per rectum revealed active left ovary with follicles of up to 11 mm diameter and enlarged right measuring 6 × cm, mass 4 3 cm. The had varied echotexture, thick hyperechoic boundary hypoechoic centre echoic foci. It tentatively diagnosed as tumour or After ovariectomy, grossly the measured 5 cm on cutting cheesy pus oozed out. abscess completely localised...
The Kafue lechwe (Kobus leche kafuensis) is a unique antelope found only in the basin of Zambia and main source local income protein. Its population has been dwindling over years supposedly due to poaching environmental pollution area without mention reproductive causes. present study was pilot which determined biometric measurements testicles adult lechwes as measures ability fertility. Testicles from 24 Bangweulu were examined August October 2009. taken using Calipers, ruler string for...
