Effects of Varying Levels of Dried Poultry Droppings on Haematology, Microbial Properties and Nutrient Utilization of Clarias gariepinus

Abstract

Effects of varying levels of Dried Poultry Droppings fed Clarias gariepinus were investigated for 84 days. The fish meal was partially and completely replaced by dried poultry droppings at 0%, 25%, 50%, 75% and 100% inclusions and was allotted T1, T2, T3, T4 and T5 respectively. Investigation conducted on the occurrence of microbes in the fish feeds revealed that T5 varied significantly (p<0.05) in Total Viable Count (TVC) (13.0×10 ) was significantly different (p<0.05) compared to other treatments. The growth performance showed that T2 varied significantly (p<0.05) in Mean Weight Gain (MWG) (29.33 g) and Feed Conversion Ratio (FCR) (0.09). The findings of the current study imply that feed microbes affected the haematological parameters of the fish and equally suppressed the growth of the fish.

Dried Pig Feces: Impacts on Growth, Haematology and Histology of Clarias gariepinus

“…In this study, the optimal growth was achieved at 50% inclusion level of DPF while 75% and 100% inclusions caused poor growth. In a similar experiment, [12] recorded a different value of 25% inclusion of dried poultry droppings fed C. gariepinus, while 100% inclusion caused poor growth as recorded in this experiment. The poor growth at the highest inclusions could be attributed with the high levels of microbe counts recorded in the feed formulated with DPF.…”

“…Data obtained were analysed using ANOVA and Duncan multiple range test was used to separate the means. Ajiboye et al; ARRB, 32(4): 1-10, 2019; Article no.ARRB.50359 2 Results: The Mean Weight Gain (MWG) revealed a significant (P<0.05) value in T3 (69.40 g), while 100% inclusion exhibited lowest MWG (21.07%). The Packed Cell Volume, Haemoglobin and Red Blood Cell values obtained decreased with increase in DPF inclusions, while an increase was observed in T4 (26.50%).…”

Growth performance and histological response of Clarias gariepinus raised on unprocessed dried leaves of Telfairia occidentalis and Mucuna utilis

“…Turner et al (2002) reported phytic acids to have a negative effect on amino acid digestibility, thereby causing problems to non-ruminant animals due to insufficient phytase needed for hydrolysis of phytic acids. Similarly, Ajiboye et al (2017) and Ajiboye et al (2019) reported poor growth performance in C. gariepinus as the level of dried poultry droppings and dried pig feces increased in the diets of the fish. The authors attributed poor growth performance recorded at 100% level of inclusion to the high level of microbes and phytochemicals in the formulated diets.…”
