Body Weight changes and Economic Implications of Feeding Uda Rams with graded levels of Supplementary Dietary Mineral Salt (Potash) in Tullun Gwanki Grazing Reserve, Silame Local Government Area, Sokoto State, Nigeria

Abstract

The study was conducted to examine weight gain and economic implications of feeding Uda rams with graded levels of dietary mineral salt (potash) in Tullun Gwanki Grazing Reserve, Silame Local Government Area, Sokoto State, Nigeria. Tullun Gwanki Grazing Reserve was purposively selected because of the predominance of pastoralists in the area. One hundred respondents were randomly selected from list of four hundred and fifty pastoralists. All the sampled respondents were contacted and interviewed using a structured questionnaire. Feeding trial using sixteen growing uda lambs in a randomized complete block design was conducted. A complete diet was formulated and divided into four treatments of four replicates per treatment; treatment A (control) without dietary mineral salt while treatments B, C and D contained potash at 1.25; 2.50 and 3.75kg/100kg diet respectively. The animals were fed ad libitum for nine weeks and daily feed and water intakes and weight gain were recorded. Data were analysed using descriptive statistics, farm budgeting and analysis of variance. Duncan’s New Multiple Range Test (DMRT) was used to separate the means where significant differences exist. Majority of the farmers (76.0%) practiced semi-intensive system of management and most of them (64.0%) used common salt in feeding uda rams. The average quantity of dietary mineral salt used by the pastoralists in Tullun Gwanki grazing reserve was 2.5kg /100kgdiet. Result of the experiment showed that rams on treatment D gave the highest average daily gain at a feeding level of 3.75kg/100kg diet and also gave the best result in terms of cost of feed/kg live weight gain (962.83N/kg) as compared to rams on treatments B and C. Similarly, net farm income obtained from the sale of Uda rams in treatment D was highest. Based on the outcome of the study, it was concluded that, farmers in Tullun Gwanki Grazing Reserve were yet to exploit minerals to the maximum tolerable by Uda sheep as they used 2.5kg rather than 3.75kg/100kg diet. Hence, it was recommended that 3.75kg/100kg diet should be used in Uda rams by pastoralists and animal breeders since it gave the best result in terms of profit and weight gain
