The study was carried out to evaluate nutrient characterization of processed cassava peels and dietary sludge supplementation on pig performance. A total of twenty-five (25) crossbred weaner pigs weighing averagely 8.5±2.5 kg were used. They were allotted into five treatments groups with three replicates in a completely randomized design. These pigs were fed twice daily, water and salt lick supplied ad libitum. The treatment diets consist of cassava peels and dietary sludge supplementation at 0% (controlled), 15%, 35%, 65% and 85% replacement of maize. Data on live weight, weight gain on a weekly basis, feed intake, body length, heart girth and height at withers were collected to determine the effect of processed cassava peel meal supplemented with dietary sludge on growth performance and economic evaluation of pigs. The data collected were subjected to one way analysis of variance (ANOVA) and significantly different means were separated using the multiple range test. Results revealed that there was a significant (p<0.05) difference on all the growth performance parameters measured as well as the economic evaluation of the feed. It can be concluded that dietary sludge mixed with processed cassava peel meal has a significant effect on the growth performance of pigs. It is therefore recommended that pig farmers should use processed cassava peel meal supplemented with dietary sludge feeds on pigs at 85% as it produces higher effects on the daily feed intake of pigs.

ANIMAL SCIENCE AND GENETICS
This study investigated the effect of dietary inclusion of differently processed cassava peel-leaf blend (CPLB) on performance and blood parameters of growing pigs. CPLB (Cassava peel: Cassava leaf; 5:1) was included in pigs diet in a feeding trial for 8wks. The CPLB replaced maize at 50%. Twenty four male crossbred (Large white x Landrace) pigs of mean weight range (20-22 kg) were assigned on a weight equalization basis to four dietary treatments having six replicates with one pig per replicate. A standard corn soya-based diet (control), Unfermented CPLB (UCPLB), water fermented CPLB (WCPLB) and microbial fermented CPLB (MCPLB) using Aspergillus tamarii as inoculum was formulated. Growth response was measured weekly, haematology and biochemical analysis were carried out at the end of 8th week. There was no significant (P>0,05) effect on growth performance and haematology parameters at the end of 8 weeks. Serum creatinine and thiocyanate were significantly (P<0,05) affected by...

Background: The use of alternative feedstuff like cassava peel and leaf in pig production is of great concern due to reduced nutrient availability caused by high fibre and antinutritional constituent. The current study investigated the effect of dietary inclusion of differently processed cassava peel-leaf blend (CPLB) on growth and blood parameters of growing pigs. Methods: CPLB (Cassava peel: Cassava leaf; 5:1) was included in pigs diet in a feeding trial for 16 wks. The CPLB replaced maize at 100%. 24 pigs of mean weight range (20-22 kg) were assigned on a weight equalization basis to four dietary treatments having six replicates with one pig per replicate. A standard corn soya-based diet (control), Unfermented CPLB (UCPLB), water fermented CPLB (WCPLB) and microbial fermented CPLB (MCPLB) using Aspergillus tamarii as inoculum was formulated. Growth response was measured and serum analysis was carried out at the end of the 8 th and 16 th week. Result: There was no significant (p>0.05) effect on growth performance at the end of the 8 th and 16 th weeks. Dietary inclusion of MCPLB resulted in higher (p<0.05) cholesterol (144.30 mmol/L) in pigs than those fed control diet (97.20 mm/L) at the end of 8th week. Pigs fed diet containing UCPLB had reduced (p<0.05) serum creatinine (0.58 mg/dl) at the end of 16 th week. In conclusion, CPLB based diet irrespective of processing method did not significantly affect growth performance and without negative effect on blood serum parameters.
This study investigated the effects of Aspergillus niger CSA35 pretreated-cassava (Manihot esculenta Crantz) peel feed (CPFG) on the body weight gain and some selected biochemical parameters of pigs. Cassava peels treated with biomass of A. niger CSA35 for a period of three weeks to initiate enzymatic digestion of peels were dried, ground and used in varying proportions to formulate pig rations in combination with other feed ingredients. Twenty 85–95 days old pigs (5.85 ± 0.70 kg) were randomly divided into four experimental groups. Group 1 received 0% CPFG amidst other feed ingredients (control), while Groups 2, 3 and 4 received 40%, 60% and 100% CPFG respectively. At the end of the feeding trial (21 days), the animals were weighed and blood samples collected for biochemical analysis. Results showed that increasing the amount of the fungus-pretreated cassava peels in pig rations increased the protein, fat and carbohydrate contents of the experimental feeds. Conversely, the percentage fibre content was reduced. The weight gain of pigs fed the control diet was significantly (p<0.05) lower than those fed with 60% CPFG and 100% CPFG but did not differ from those fed 40% CPFG. Serum calcium and albumin levels were observed to be significantly lower (p<0.05) in control group than in treatment groups. The highest serum calcium level was, however, observed in 100% CPFG group. Activities of liver function enzymes and serum creatinine level of pigs fed the formulated diets did not significantly differ from those of control unlike their serum urea levels. It was concluded that pig feeds formulated with cassava peels pretreated with A. niger CSA35 enhanced feed's nutritive value and metabolisable energy, boosted serum albumin and calcium levels in pigs, increased pigs body weight and are health-friendly since the feeds did not pose threat of liver damage in the pigs investigated.
ANIMAL NUTRITION AND FEED TECHNOLOGY
Olafadehan, O.A. 2011. Haematological parameters, serum constituents and organ development of growing rabbits as affected by feeding of processed cassava peels. Animal Nutrition and Feed Technology, 11: 41-51. The effects of feeding ensiled, sun-dried and retted cassava peel meal on the blood constituents and organ development were studied using growing rabbits in a 9-week experiment. Four diets were formulated such that the control diet did not contain cassava peel meal (CPM) while the three other diets contained 200 g/kg of ensiled cassava peel meal (ECPM), sun-dried cassava peel meal (SCPM) and retted cassava peel meal (RCPM), respectively. Thirty-two rabbits, aged 6 week-old of mixed breeds, were allocated to a completely randomized design, with eight animals per treatment. The rabbits were slaughtered and used for the blood constituents and organ development study. All the processed CPM had much lower concentration of hydrogen cyanide (HCN) than the unprocessed CPM indicating t...
