背景:雄性和雌性食用动物都被宰杀。一些奶牛,母羊和被屠宰的母羊被发现有可行的胎儿,导致胎儿浪费和未来替代库存的损失。胎儿浪费约占撒哈拉以南非洲牲畜数量下降的20%-25%。屠杀怀孕的奶牛,母羊和母羊确实造成了经济损失,并威胁到粮食安全,从而减少了快速增长的人口可用的动物蛋白。在包括乌干达在内的大多数发展中国家,健康人类发育的蛋白质需求不足。在屠宰场中评估了与胎儿浪费相关的患病率和经济损失。
目的:本研究的目的是评估研究屠宰场浪费的发生率,并估计相关的经济损失。
方法:在屠宰场居民肉类检查员的支持下,研究人员在研究期间检查了所有屠宰的雌性动物。用锋利的刀穿过长轴,将尸体换药后从屠宰的动物中获得的妊娠子宫取出内脏,以恢复胎儿。使用卷尺测量回收的胎儿的冠部臀部长度(CRL),称重并归类为第一,第二和第三个三个月。通过计算怀孕动物占屠宰雌性动物总数的百分比来确定屠宰的怀孕动物的患病率。经济损失是根据出生时的货币损失估计的,断奶,成熟,断奶和成熟时的car体损失。
结果:总屠宰量为牛604(73.6%),山羊169(20.6%)和绵羊48(5.9%)。胎儿浪费的总体患病率为21.9%。按物种划分的胎儿浪费总数包括160头(88.9%)头奶牛,8头(4.4%)小母牛,4只(2.2%)和8只(4.4%)母羊。按三个月计算,奶牛的胎儿浪费包括62只(38.8%),26(16.25%)和72(45.0%),第二和第三个三个月,分别,转换为13,055美元的损失。胎儿浪费很高,相关的经济损失也很大,这破坏了国家牛群的可持续性。农民应注意与胎儿浪费相关的经济损失和长期影响,并劝阻这种做法。需要一项政策来阻止农民出售怀孕的动物进行屠宰。
结论:总共168头牛,在60天的研究期内浪费了8只山羊和12只绵羊胎儿。这些胎儿浪费在出生时转化为13,224美元的货币损失,断奶时货币损失31,849美元,到期时货币损失57,0896美元。
Both 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.
The study was cnducted to assess the prevalence of feotal wastage at the study abattoir and estimate the associated economic losses.
The 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.
The 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$13,055. Foetal wastage was high and the associated economic losses were substantial which undermines sustainability of the national herd. Farmers should be sensitised about the economic losses and long-term impact associated with foetal wastage and dissuaded from this practice. A policy is needed to deter farmers from selling pregnant animals for slaughter.
A total of 168 bovine, 8 caprine and 12 ovine foetuses were wasted within 60 days study period. These foetal wastages translated to US$ 13,224 monetary losses at birth, US$ 31,849 monetary loss at weaning and US$ 57,0896 monetary loss at maturity.
