Item Unknown Analysis of scope and economic efficiency in poultry-fish enterprises in Imo State, Nigeria(Federal University of Technology, Owerri, 2022-02) Opara, Thaddeus C.This study analysed the scope and economic efficiency of poultry-fish enterprises in Imo State, Nigeria. The specific objectives were to: examine the Socio economic and enterprise characteristics of fish and poultry farmers, estimate cost function from profit function to determine scope efficiency of poultry-fish enterprises, determine how scope and economic efficiency related to the use of specific inputs or the production of specific output, evaluate the determinants of scope efficiency and economic efficiency in poultryfish enterprises in the study area. A multi –stage sampling technique was used to select 210 respondents comprising of 60 fish farmers 60 poultry farmers and 90 joint poultryfish farmers. Structured questionnaire were used to elicit information from respondents while descriptive statistics, inferential statistics. Quadratic regression model, Tobit regression model and analysis of variance were used for data analysis. Findings from the study showed that most of the farmers in the three categories were males, 57.1% for fish, 62.3% for poultry and 66.7% for joint enterprises respectively. Most of the Respondents were between 41 and 60 years age bracket, 65.1% for fish 80.3% for poultry and 58.3 for joint enterprises. The distribution of respondents by marital status showed that most of the farmers were married 80.9% for fish, 75.4% for poultry and 81.9% for joint enterprises. Majority of the respondents had household sizes of 4 to 5 persons, 65.1% for fish, 55.7% for poultry and 63.9% for joint enterprises. 69.8% of fish farmers and 67.2% of poultry farmers had 6 to 10 years farming experience while majority of joint farmers (56.9% had 1-3 years of farming experience. Most sole farmers were small scale farmers 39.7% for fish and 42.6% for poultry while most joint farmers were large scale farmer (75%). The three categories of farmers had poor access to credit with only 19.4 % of joint farmer able to access above N300, 000 credits. In this research, cost functions were recovered from unrestricted profit functions and were used to calculate scope efficiency. The main scope efficiency was 0.025 indicating that the joint production of fish and poultry enterprises reduces total cost by 2.5%. The mean economic efficiencies were 0.72 for fish, 0.68 for poultry and 0.77 for joint enterprises. This indicated that farms could reduce cost by producing at the lowest possible cost. The correlation of scope and economic efficiency with output quantities was positive and significant at 1% level suggesting that the joint production of fish and poultry on the same farm resulted in cost advantage. Also the correlation of scope and economic efficiency with expense ratio were all significant at 1% level which revealed that larger farms tends to have more scope and economic efficiency scores. Again scope and economic efficiency are significantly determined by level of education, farming experience, pond size, and flock size as well as credit amount. It is recommended that educational packages and appropriate training could be necessary to teach farmers those farming practices that encourages cost complementarities and financial institutions should be encouraged to improve on the volumes and terms of loans extended to farmers.
