Traditionally, edible beef and chicken offal were available and sold in rural meat and informal markets around Gaborone, but recently upmarket retail stores of Gaborone sell these products. The study was done over a period of twelve months. Amongst the offals noted in the retail stores were ox tail, tongue, spleen, ox heel, kidneys, intestines, rumen, omasum, liver and ox heart for beef and feet, liver, gizzards, intestines, necks and kidneys for chicken. Offals were cheaper than the cheapest standard beef and chicken cuts being the chuck/brisket or stewing beef for beef and breast for chicken. Green beef offals were generally cheaper than red offals. The most expensive beef offal was ox tail at ~P60.00, and the cheapest offal was ox heel at ~P19.95 (USD1.00 ~ BWP11.00). For chicken, the gizzards were the most expensive at ~P49.45, with the necks being the cheapest at ~P26.59. Improved marketing and utilization of offals will reduce meat wastage.

Sixty two weeks old Abor-acre broilers were randomly divided into 5 treatment groups. Each treatment group had 3 replicates of 4 birds each. Birds in each treatment group were fed feed from one of five companies. Feed intake and body weights were determined. Blood samples were analyzed for hematological parameters. Feeds were analyzed for aflatoxin concentration using reverse phase High Performance Liquid Chromatography (HPLC). Aflatoxigenic fungi were identified by sequencing of the fungal ITS region. The major fungal contaminants identified in most of the feed samples were Aspergillus and Rhizopus species. Total aflatoxin content (AFB1+AFB2+AFG1 +AFG2) of the feeds ranged from <0.8 to 370±120 µg/kg. Feeds from three companies had aflatoxin concentrations above the European Community Regulatory Limits (ECRL, 20 μg/kg). Aflatoxin level was positively related to packed cell volume (PCV) and hemoglogin (Hb), although the relationship was not statistically significant. PCV and Hb were positively related. A negatively significant relationship was observed between the aflatoxin levels and WBC of the birds, feed intake and reduced body weight possibly because of the high aflatoxin concentrations in the feeds.
