Indiscriminate slaughter of pregnant goats for meat in Enugu, Nigeria: Causes, prevalence, implications and ways-out.

BACKGROUND: The indiscriminate slaughter of pregnant goats (SPGs) undermines meat production and food security especially in developing countries. It also connotes animal cruelty, depletion of goat population and may enhance the spread of zoonotic pathogens inhabiting the female reproductive tract during carcass processing. Consequently, this study determined the causes and prevalence of slaughtering pregnant goats for meat in Enugu, Nigeria. The study also estimated the economic losses associated with SPGs, discussed the negative public health consequences and suggested the ways-out. METHODS: Structured, validated and pilot-tested questionnaire was used to ascertain the reasons for SPGs for meat among 78 willing and randomly selected respondents. The questionnaire survey was conducted in the form of interview. Pregnancy statuses of the goats slaughtered were ascertained by visual inspection and palpation of the eviscerated and longitudinally incised uteri and the horns for macroscopic evidence of pregnancy. Ages of the dams were estimated by dentition method. Estimation of the gestational age was performed by crown-rump length method. The study lasted for six months, comprised of three months (December to March) during the dry/hot season and another three months (May to August) during the wet/rainy season. Economic loss estimation was based on the current monetary values of a matured (30 kilogram) goat and one kilogram of chevon in Enugu, Nigeria; which was determined through market survey. Pearson's Chi-square test was used to determine whether there were significant (P<0.05) statistical associations between SPGs and age and season. RESULTS: Major reasons adduced for SPGs were: economic hardship (41%), ignorance of the goat's pregnancy status (21%), increased demand for chevon (13%) and feed scarcity during drought (11%). Of the 1,658 does examined during the six months study, 589 (35.5%) were pregnant. The majority (876/1658, 52.8%) of the female goats slaughtered were in their active reproductive age of ≤ 4 years, while 782 (47.2%) were aged > 4 years. Similarly, majority (1007/1658, 60.7%) of the does/nannies were slaughtered during the dry/hot season. A total of 907 foetuses at first (n = 332, 36.6%), second (n = 486, 53.6%) and third (n = 89, 9.8%) trimesters of gestation were recovered from the 589 PGs. Singleton, twin and triplet pregnancies were observed in 312 (53%), 236 (40%) and 41 (7%) PGs, respectively. About ₦34.44 million ($83,390) would have been earned if the foetuses were born alive and raised to maturity. Additionally, 19,136 kg of chevon, valued at ₦47,841, 000 ($115,838), which would have accrued from the wasted foetuses was also lost. CONCLUSION: Considering the economic, zoonotic and livestock production implications of this work, frantic efforts to reduce SPGs in Enugu, Nigeria is imperative. This could be achieved through advocacy, goat farmers' enlightenment, ante-mortem pregnancy diagnosis, provision of subsidized feed materials during the dry season and strict enforcement of the Nigerian Meat Edict law, which proscribes unapproved slaughter of gravid animals. These measures may improve food safety and security, improve goat reproduction and production, reduce protein malnutrition, limit dissemination of zoonotic pathogens during carcass processing and hence protect public health in Nigeria.

Bovine fetal wastages in Southeast Nigeria: prevalence, causes and public health implications.

Slaughter of pregnant animals for meat is unethical, counterproductive and enhances zoonotic disease spread. This study determined the prevalence and reasons for slaughtering pregnant cows (SPCs) for meat. Pregnancy status of cows slaughtered was determined by evisceration and longitudinal incision of the uterus for presence of fetus. Closed-ended questionnaire was used to elicit information on causes of SPCs and disposal of eviscerated fetuses. Of the 851 cows slaughtered, 17.4% (148/851) were pregnant. Of the 148 pregnant cows, 87 (58.8) were slaughtered during dry season while 43.2% (64/148) of the recovered fetuses were in their third trimester. Reasons adduced for SPCs by the participants in the questionnaire were: ignorance of the animals' pregnancy status, 69.7% (n=119), high demand for beef, 61.3% (n=148), buyers preference for large-sized animals, 47.9 (n=148), economic hardship, 52.1% (n=148) and disease conditions, 42.9% (n=148). Fetuses or uterine contents were sold for human consumption, 17.6% (n=119), preparation of dog food, 27.7 (n=119) or disposed by open refuse dump method, 54.6% (n=119). The 17.4% SPCs prevalence is unacceptably high. This warrants ante-mortem pregnancy diagnosis in the slaughterhouses and strict implementation of the Animal Welfare Act (Meat Edict of 1968) to conserve livestock production and limit animal cruelty and spread of zoonoses.

Slaughter Conditions and Slaughtering of Pregnant Cows in Southeast Nigeria: Implications to Meat Quality, Food Safety and Security.

The increase in the slaughter of pregnant cows (SPCs) for meat (except as may be approved by veterinarians on health grounds to salvage the animal) is unethical. SPCs for meat is also counterproductive, detrimental to food security, and may enhance zoonotic disease transmission. In this context, therefore, this current study examined slaughter conditions and the slaughtering of pregnant cows, and the implications for meat quality, food safety, and food security in Southeast Nigeria. The direct observational method was employed to examine the slaughterhouse activities, from when the cattle arrived at the lairage to the post-slaughter stage. A pre-tested and validated closed-ended-questionnaire was used to elicit information on causes of the SPCs and the method of disposal of eviscerated foetuses. Pregnancy status of cows slaughtered was determined by palpation followed by visual examination of the eviscerated and longitudinal incised uteri. The study lasted for six months during which 851 cows out of 1931 slaughtered cattle were surveyed. Assessment/decision-making protocol of slaughterhouse conditions, welfare conditions of slaughter-cattle, reasons for sale or slaughter of pregnant cows, distribution of pregnant cows slaughtered, method of disposal of eviscerated foetuses, and estimated economic losses of SPCs were delineated. Of the 851 cows examined, 17.4% (148/851) were pregnant while 43.2% (64/148) of the total foetuses recovered were in their third trimester. Major reasons adduced for SPCs by proportion of involved respondents were: ignorance of the animals' pregnancy status (69.7%, 83/119), high demand for beef (61.3%, 73/119), preference for large-sized cattle (47.9%, 57/119), economic hardship (52.1%, 62/119) and diseases conditions (42.9%. 51/119). The conduct of SPCs for meat would not be profitable. This is because within six months, an estimated loss of about 44,000 kg of beef, equivalent to ₦ 70.1 million or $186,400 would be associated with SPCs and the consequential foetal wastages. If losses were to be replicated nationwide across slaughterhouses, 4.3 tons of beef estimated at ₦ 8.6 billion or $23 million would be wasted. Improving slaughter conditions and the welfare of slaughter-cattle in Nigerian slaughterhouses through advocacy, training of slaughterhouse workers, and strict implementation of laws promoting humane slaughter practices is imperative. Preventing SPCs for meat and inhumane slaughter practices at the slaughterhouse would enhance the welfare needs of slaughter cattle, grow the national herd size, and improve meat safety as well as food security.

Antimicrobial drug usage pattern in poultry farms in Nigeria: implications for food safety, public health and poultry disease management.

Good antimicrobial drug stewardship in food­producing animals boosts productivity and limits transmission of zoonotic pathogens, but the imprudent usage is counterproductive. A nation­wide survey to determine the pattern of antimicrobial drug usage in poultry was therefore conducted across 12 of the 36 States in Nigeria. The survey was conducted using structured questionnaire designed to elicit information on socio­demographics, pattern of antimicrobial drug usage and awareness of the consequences of imprudent use of antimicrobials in food­producing animals, among 2,402 randomly selected poultry farmers. Critically important antimicrobials, belonging to the WHO's lists of 'Highest' and 'High' priority antibiotics, were administered sub­therapeutically for prophylaxis and growth enhancement purposes. Many diseases that warranted the antimicrobial administration were of viral etiology. Only 64.2% of the farmers administered the drug based on veterinary doctors' prescription. Majority (62.3%) of the farmers did not observe recommended withdrawal period after the drug administration. Awareness of the respondents on consequences of non­prudent agricultural use of antimicrobials was generally poor. There is need for enlightenment of the farmers on the benefits of prudent agricultural use of antimicrobials. Immediate discontinuation of sale of essential antimicrobials as over­the­counter drugs is imperative to safeguard their therapeutic efficacy and curtail spread of antimicrobial­resistance organisms.

Epidemiology of infections with zoonotic pig parasites in Enugu State, Nigeria.

Pig production is an important component of animal agriculture in Nigeria but zoonotic parasites constrain the production and make pork unsafe for human consumption. This epidemiological study was therefore conducted, to ascertain the prevalence and determinants of Taenia solium cysticerci and Ascaris spp infections in pigs in Enugu State. Presence of cysticerci was determined by post-mortem examination of pig carcasses while pig faeces were coprologically examined for presence of Ascaris spp egg, according to standard parasitological protocol. Structured questionnaire was used to elicit information on pig farmers' involvement in practices predisposing to parasitic infections and deworming progammes in 107 piggeries surveyed. Cysticerci were detected in 3.51% (12/342) of pig carcasses inspected. Overall prevalence of Ascaris spp. infections were 38.3% (41/107) and 14.3% (63/441) at farm and individual pig levels respectively. Major determinants of the infection and the percentage of farmers involved were: eating on duty (66.4%), open defecation (35.5%) and semi-extensive husbandry system (62.3%). Others are non-availability of deworming programme (54.4%), rearing pigs of different ages together (41.9%), non-disinfection of feeding or water troughs (41.2%) and early weaning (54.3%). Cognizant of the zoonotic potentials of Ascaris spp and Taenia solium cysticerci, the prevalence found for the parasites are significant from public health and food safety points of view. This underscores the need for cost-effect control measures against the parasites, using a coordinated One Health approach; in order to boost pig production, limit spread of the zoonoses and hence, the public health consequences thereof.
