INFLUENCE OF INCREASE IN PRICE ON POULTRY PRODUCTION IN NIGERIA

2.2 THEORETICAL FRAMEWORK

One of the key pillars on which the neoclassical theory of the firm stands is the assumption of profit maximization. It is a simple but controversial assumption that states that the objective of the firm is wholly and single-mindedly the maximization of profit. Many adherents of profit maximization have advanced a lot of arguments in support of their position. These include one based on the realism and predictive value of the assumption of profit maximization itself and the other based on a supposedly long-run survivalist instinct of the firm. But there are three types of factors, which may militate against a firm achieving maximum profit (Olayemi, 2004). They are:

(i) Uncertainty and lack of information needed for rational decision making;

(ii) The pursuit of multiple objectives by the firm of which profit earning may be only one of them;

(iii) Restraint imposed on the single-minded pursuit of profit maximization by such other considerations as the prevention of potential entry of new firms as competitors, the long-term survival of the firm and self-preservation of the top management of the firm, which short-run profit maximization alone, would not guarantee. The issue of profit maximization is, therefore, not about whether the simple types of firms envisaged in traditional theory do strive to earn the highest profit achievable, given real-life uncertainty, inadequate information and other constraints, or whether they behave as if they maximize profit, but rather about achieving a minimum satisfactory profit since firms can survive, even over the long period, without maximizing profit, if there are adequate barriers against actual entry or threat of new entry of firms in the forms of, say, limit-pricing, government legislation, product differentiation, absolute cost advantage, large initial capital requirement for entry, and large economies of scale.

Origin and Domestication of Chicken

Nigeria is a country with heavy human population and this population is continuously on the rise. This increase had lead to the high demand for the available animal and poultry products in all parts of the country. Among the cheapest and highly affordable protein source for this teeming population is mainly the poultry products. Poultry, particularly chickens are very important and has been recognised as an important genetic resource among the avian species (Olowofeso et al., 2005). Genetic evidence confirms that chickens are derived from multiple maternal origins in Asia (Liu et al., 2006). Chickens are the most widely distributed of all livestock species in Nigeria with a population of 166 million birds (FAOSTAT, 2007). Chickens play very significant socio-cultural and economic roles in most African societies. Quantifying the structure of genetic diversity in different African chicken populations is of significance in optimizing conservation and utilization strategies. The description of Nigerian local chickens is based on phenotypic traits (Nwosu et al., 1985; Adebambo et al., 1999). Such information if complemented with findings obtained using molecular markers could be useful in formulating long term inference or plans for genetic improvement programs. A detail genetic study of chicken populations in Nigeria is therefore imperative so as to integrate the resource into the poultry sector. The genetic variations of the chicken populations in the country need investigation so as to identify populations of particular merit.
