Study of Incidence of Gross Urogenital Lesions and Abnormalities on Does Slaughtered at Nyagatare Slaughterhouse, Eastern Province, Rwanda

Abstract

Reproductive and urinary tract abnormalities are a cause of infertility, reproductive inefficiency, and economic losses in goats. The aim of this study was to investigate the occurrence and nature of reproductive and urinary tract abnormalities encountered in female goats slaughtered at Nyagatare abattoir in the Eastern Province of Rwanda. Reproductive and urinary organs from 369 female goat carcasses were opened by incision and then given a thorough macroscopic examination by visually inspecting and palpating for evidence of abnormalities. The results showed that there was an overall occurrence of 7.8% reproductive organ/tract abnormalities and 10.6% urinary organ/tract abnormalities. Ovarian hypoplasia was the reproductive abnormality with the highest overall occurrence (32.3%) and renal calculi were the urinary organ abnormality with the highest occurrence (38.1%). 95.2% of the reproductive organ/tract abnormalities observed usually result in infertility and 91.3% of the urinary organ/tract abnormalities observed result in economic losses through condemnation of kidneys at slaughter. The high incidence of the observed urinary organ/tract abnormalities represents a potential public health challenge. There was no significant difference in the occurrence of reproductive organ/tract abnormalities according to breed (p > 0.05, n = 31). There was also no significant difference in the occurrence of urinary organ abnormalities according to breed (p > 0.05, n = 42).

Prevalence of Haemonchus contortus Infections in Sheep and Goats in Nyagatare District, Rwanda

“…A random digits table was then used for simple random sampling of animals within each sector. Male and female sheep (local, cross, and South African Meat Merino breeds) and the small East African goat and its crosses with the Alpine, Anglo-Nubian, and Angora goat breeds raised extensively on communal land in the five sectors were sampled [ 24 ].…”

Estrus and pregnancy rate of Simmental-Ongole Crossbred and Ongole Grade heifer after being synchronized and inseminated

“…The abnormality reproductive organ and physiological disorders are factors causing infertility and sterility in cow buffalo (Azawi et al, 2008). Abnormalities of reproductive tract and ovaries are factors causing infertility in goats, reaching 91.3% (Mushonga et al, 2017).…”

Chemical analyses and evaluation of the anthelmintic effects of Origanum majorana essential oil, in vitro and in vivo studies

“…Different studies reported the overall prevalence of H. contortus infection in small ruminants. In Europe, the prevalence of H. contortus shows high values, e.g., 77% in Switzerland, 73% in Italy (Rinaldi et al 2015); in South Africa, the prevalence has been reported at 68% (Mushonga et al 2017). In Tunisia, the overall prevalence of Haemonchus species in sheep, goats and cattle was 17, 33.6 and 7.23%, respectively (Akkari et al 2013).…”
