“…The disparity could be because of the prospective study carried out by the latter in which data were collected by the researchers themselves as compared with this retrospective study. Aniebo et al, (2009) reported the same disparity in Rivers State, Nigeria, where he cited a daily slaughter figure of 18 cattle and 11 goats in contrast to the records at the State Ministry of Agriculture which showed that 6 cattle and no goats were inspected and slaughtered daily at the same slaughterhouse. The monthly averages of slaughtered cattle reported in this study were higher than the 174 (40.…”

Meat consumption demand is increasing with the growing population; however, livestock foetal wastage in the abattoirs/slaughter slabs in Nigeria is being documented. The trend of slaughtering pregnant animals is against the existing meat edict of 1968 and this accounts for a decrease in livestock production and huge financial losses which invariably affects the livestock economy. Hence, a 5-year retrospective study (2012)(2013)(2014)(2015)(2016)) was conducted to assess the level of economic implication of foetal wastages in cattle and goats slaughtered in Jos abattoir. The data collected were analyzed using Microsoft Excel, tables, and a graph chart. The total number of cattle and goat slaughtered and their foetuses were reported as documented. A total of 26,242 cattle and 4,612 goats were slaughtered, representing a yearly 5,250 and 922, monthly 437 and 77, and daily15 and 2.6 averages respectively. Out of these a total of 1,346 (4.5%) and 1,044 (22.6%) fetuses were wasted representing a yearly 269 and 209, monthly 22 and 17 and daily0.75 and 0.6for cattle and goats respectively. The economic loss associated with the total foetal wastages for cattle and goats in the present study was estimated at ₦174,980,000 ($571,830.07) and ₦10,044,000 ($328,235.29) respectively. The annual averages of cattle and goat fetal wastage are ₦34,970,000

“…Yearly, total slaughtered figure was highest in 2013 for cattle (6,302) and in 2012 for goats (1,125), while it was lowest in 2015 for both cattle (4,405) and goats (750). A total number of cattle and goats slaughtered at Jos abattoir and the trend of fetal wastages in both species is shown in Figure 1.…”

“…This study also assumed that volume of waste generated from the slaughter of sheep is equal to that for goat. The estimated figures from Aniebo et al (2009) were therefore applied to sheep. Quantity of meat produced was also estimated using data (average) from the Ministry of Food and Agriculture (MOFA) ( Table 2), computed from carcass weight and number of livestock slaughtered.…”

“…Additional information was collected through questionnaire administered to butchers and interviews with key informants (veterinary experts and meat inspectors) using interview schedule. Waste materials generated from abattoir operations was estimated based on calculations by Aniebo et al (2009) (Table 1). The computations were done using average data on body weight for the respective ruminants and carcass weight per 1,000 kg.…”

“…Blood, one of the major dissolved pollutants in slaughterhouse wastewater, has the highest COD of any effluent from abattoir operations [16]. If the blood from a single cattle carcass is allowed to discharge directly into a sewer line, the effluent load would be equivalent to the total sewage produced by 50 people on average day [6].…”

Abstract:The objective of this investigation was to optimize and evaluate the bioenergy production potential and COD removal efficiency of a semi-continuous anaerobic digester from slaughterhouse wastewater. The performance of the pilot scale anaerobic digester was evaluated at the OLRs of 0.32, 0.51, 1.16 and 2.31 kg m −3 day −1 under mesophilic environmental condition (29.6±1.40°C). The COD removal efficiencies and methane yield in the pilot scale digester were in the range of 43.39 to 84.54% and 0.09±0.03 to 0.22±0.02 m 3 /kg COD removed, respectively with the maximum volumetric methane production (0.93±0.17m 3 /day) was achieved at the OLR of1.16 kg m −3 d −1 corresponding to an optimum methane yield of 0.20 m 3 CH 4 per kg COD removed. Generally, the results of this study showed that anaerobic digester is efficient on generating bioenergy while treating high strength wastewater such as slaughterhouse wastewater. Hence, a full scale anaerobic digester should be developed and used to treat the wastewater generated in the slaughterhouse industries in Ethiopia where almost all the slaughterhouses discharge their wastewater to the nearby streams without prior treatment.
