Abstract
AbstractBackgroundBoth male and female food animals are slaughtered for meat. Some cows, ewes and does slaughtered are found with viable foetuses resulting in foetal wastage and loss of future replacement stock. Foetal wastage accounts for about 20%–25% of the decline in livestock numbers in sub‐Saharan Africa. Slaughter of pregnant cows, ewes and does results in economic losses and threatens food security with consequent decrease in available animal proteins to the fast growing human population. Protein requirement for healthy human development is inadequate in most developing countries including Uganda. The prevalence and economic losses associated with foetal wastage were assessed in an abattoir.ObjectivesThe study was cnducted to assess the prevalence of feotal wastage at the study abattoir and estimate the associated economic losses.MethodsThe researchers supported by abattoir resident meat inspectors examined all slaughtered female animals during the study period. Gravid uteri obtained from slaughtered animals after dressing of carcasses were eviscerated using a sharp knife across the long axis to recover foetuses. The crown rump lengths (CRLs) of the recovered foetuses were measured using a tape measure, weighed on a scale and categorised into first, second and third trimesters. Prevalence of pregnant animals slaughtered was determined by calculating the percentage of pregnant animals over the total number of female animals slaughtered. Economic losses were estimated based on the monetary losses at birth, weaning, maturity, and carcass loss at weaning and maturity.ResultsThe aggregate slaughters were bovine 604 (73.6%), caprine 169 (20.6%) and ovine 48 (5.9%). The overall prevalence of foetal wastage was 21.9%. The aggregate prevalence of foetal wastage by species include 160 (88.9%) cows, 8 (4.4%) heifers, 4 (2.2%) does and 8 (4.4%) ewes. Foetal wastage of cows by trimester included 62 (38.8%), 26 (16.25%) and 72 (45.0%) in first, second and third trimesters, respectively, translating into loss of US$13,055. Foetal wastage was high and the associated economic losses were substantial which undermines sustainability of the national herd. Farmers should be sensitised about the economic losses and long‐term impact associated with foetal wastage and dissuaded from this practice. A policy is needed to deter farmers from selling pregnant animals for slaughter.ConclusionsA total of 168 bovine, 8 caprine and 12 ovine foetuses were wasted within 60 days study period. These foetal wastages translated to US$ 13,224 monetary losses at birth, US$ 31,849 monetary loss at weaning and US$ 57,0896 monetary loss at maturity.
