ABSTRACT This paper uses a translog cost function approach to study the farm-level demand for poultry feed in Kenya. The study estimates the demand elasticities of the three common types of poultry feed; mixed feed, grain, and leafy vegetables. The estimated model was used to obtain estimates of Marshallian demand elasticities for poultry feed in Kenya for male-headed and female-headed households. The elasticities reported can be used by researchers and policy analysts to evaluate policy effects of changes in feed demand quantities within the livestock economy in Kenya. Moreover, these parameters can provide more reliable estimates of the total change in feed demand than relying on subjective measures of elasticities. Furthermore, the results of this study are essential in enhancing gender equitable policy formulation. Our findings show that own price elasticities of demand for all the feed types are negative and less than unit in absolute value for the sample of farmers surveyed, indicating that the feed types are relatively inelastic. The cross-price elasticities indicate that vegetables and grain are compliments while the rest of the poultry feed types are substitutes. The results also show that there are substantial gender differences in feed demand and elasticities of feed demand with respect to feed prices.

肯尼亚家禽饲料需求的性别分析

摘要 本文使用 translog 成本函数方法来研究肯尼亚农场对家禽饲料的需求。该研究估计了三种常见家禽饲料的需求弹性；混合饲料、谷物和叶类蔬菜。估计模型用于获得肯尼亚男户主和女户主家庭对家禽饲料的马歇尔需求弹性的估计。研究人员和政策分析师可以使用报告的弹性来评估肯尼亚畜牧经济中饲料需求量变化的政策影响。此外，与依赖弹性的主观测量相比，这些参数可以对饲料需求的总变化提供更可靠的估计。此外，这项研究的结果对于加强性别平等政策的制定至关重要。我们的研究结果表明，在被调查的农民样本中，所有饲料类型的自身需求价格弹性为负且绝对值小于单位，表明饲料类型相对缺乏弹性。交叉价格弹性表明蔬菜和谷物是互补品，而其余的家禽饲料类型是替代品。结果还表明，饲料需求和饲料需求相对于饲料价格的弹性存在显着的性别差异。
