The experiment lasted 90 days. Sixteen bucks aged 7-9 months and averaging 8.0± 0.01kg in weight were divided into 4 groups of 4 with each group randomly assigned to one of the treatments in a completely Randomized Design. The four treatments were formulated to contain 0, 7.5, 10 and 12.5% of jackfruit seed meals respectively. The values for growth parameters were not significantly (P>0.05) different except for feed conversion ratio (FCR). The bucks on treatment 3 (10% JFS meal) have the least FCR (3.82) and the least cost/kg weight gain (₦293.00) though not significantly (P>0.05) different with a corresponding increase in gross margin (₦4113.00) of the same treatment. The haematological and serum biochemical indices studied were significantly (P<0.05) different across all the treatments except for eosinophils. The highest total protein (7.13g/dl) and calcium (5.76 mmol/l) content were recorded in T 3. This result has indicated safe nutritional regimes of JFS meal and its inclusion up to 10% is ideal for optimum cost/kg weight gain which is suggestive of enhanced buck production.

The birds which had, on day 10 received infectious bursal disease vaccine started dying a day after the administration of Newcastle disease vaccine. The clinical signs, postmortem findings and response to treatment were used to confirm coccidiosis. The rapid onset of the clinical disease and the high modality rate (33% over a period of 4 days) was considered to have been induced by the Newcastle disease vaccine administration. A diagnosis of sub-clinical coccidosis and institution of prophylactic anticcocidial therapy before Newcastle disease vaccination would have obviated the clinical disease.

It was discovered that a total of 4196 cattle were slaughtered of which 277 showed signs indicating BTB. This figure represents about 6.60% of the total numbers of cattle slaughtered during the period. The highest rate of the BTB prevalence was recorded in 2013 with 98(6.89%) and the lowest incidence was recorded in the year 2012 with 84(5.76%) reported cases. These figures present BTB as major problems to successful livestock business as well as threat to public health and food safety. The paper further describes in facts, figures, tables and charts about the subject matter. This therefore calls for action and cooperation among stakeholders in all sectors to ensure that the threat of BTB is contained and possibly eradicated.

Pig production remains one of the veritable sources of supply of animal protein. The importance of nutrition in pig production cannot be overemphasized and meeting the nutrient requirement of livestock is a major concern to nutritionist. Most pig farmers are ignorant about the nutrient requirements of pigs and how feed ingredients can be manipulated to satisfy these requirements and thus, feed their animals with various feed products without recourse to the health and physiological implications for the animals. Although, nutritional status of an animal is independent of dietary intake and effectiveness of metabolic processes, feed quality is particularly a major factor that ensures the success or failure of pig production. Diets have been established to have measurable effects on blood components and the latter in turn are widely used in nutritional evaluation and survey of animals. Systemic...

In Nigeria, different poultry species contribute to the animal protein supply of the populace in terms of eggs laid and meat produced. Feeding poultry for optimum growth production requires that the birds consume appropriate balanced diets for the health and productivity, it is important that they be fed diets that meet their nutritional requirements. Dietary components affect the blood profile of healthy birds. The blood transports or conveys nutrients and materials to different parts of the body. Therefore, whatever affects the blood, either nutrition or drugs will certainly affect the entire body adversely or moderately in terms of health, growth, maintenance and reproduction. Thus, a readily available and fast means of assessing, clinical and nutritional health status of animals on feeding trials may be the use of blood analysis, because ingestion of dietary components have measurable effects on blood composition.

Blood is important and reliable medium for assessing the physiological and health status of farm animals and haematology is the study of the morphology and physiology of blood. Haematological parameters are those parameters that are related to the blood and blood forming organs. Haematological analysis involves the determination of the various blood parameters and the parameters include erythrocyte (red blood cells (RBC)), leucocyte (white blood cells (WBC)), Packed Cell Volumes (PCV) among others. Haematological examination is among the methods which may contribute to the detection of some changes in health and physiological status, which may not be apparent during physical examination but which affect the fitness of the animal. Thus, haematological parameters are good indicators of the physiological status of farm animals. Furthermore, there is a great variation in haematologi...

Using multistage random sampling procedure, 278 respondents were selected. Analytical techniques used were simple descriptive statistics and Linear Programming techniques. Mean age for the male and female respondents were 40 and 41 years respectively. Respective mean farm sizes of the male and female respondents were 1.89 and 1.39 hectares. The result also reveals that 52% male respondents acquired their land through family inheritance and 42% through leaseholds while majority (85.3%) of the female respondents acquired their land through leaseholds. The acquisition of farm lands through inheritance favoured more male respondents (52%) than their female counterparts (11.6%). The implication of this is that gender disparity in terms of land acquisition was prevalent in the study area and this will limit the productivity of the female fadama crop farmers. Nine crop combination patterns or enterprises were identified to include sole maize, sole rice, sole sorghum, maize/rice, rice/sorghum, maize/sorghum, maize/rice/sorghum, maize/vegetables and maize/rice/vegetables. Theresult on the resource utilization pattern for male farmers showed that four of the resource constraints were fully utilized in arriving at the optimal solution. These are labour, agro-chemicals, inorganic fertilizer and seeds. The dual (shadow) prices of the fully utilized resources indicate the amount by which the objective function will increase if these inputs are increased by one unit. That is, total gross margin will increase by N369.32, N3384.95, N200.31 and N864.91 for one-man day increase in labour, one litre increase in agro- chemicals, one-kilogram increase in inorganic fertilizer and one kilogram increase in seed respectively. Similarly, for the female farmers, resource utilization pattern also showed three of the resource constraints were fully utilized in arriving at the optimal solution. These inputs are labour, agro-chemicals and inorganic fertilizer. This also means that total gross margin will increase by N65.57, N3671.84 and N279.27 for one-man day increase in labour, one litre increase in agro- chemicals and one kilogram increase in inorganic fertilizer respectively. The non fully utilized resources among the male farmers was land (452.72 ha) while the non fully utilized resources among the female farmers were land (183.83 ha) and seeds (1,016.02 kg), indicating that these resources were in-efficiently utilized by the male and female fadama crop farmers in the study area. The study recommended that a prototype combination of crop enterprises that emanated from the linear programming should be integrated into the extension education package of the male and female fadama farmers to enable them improve on their farm income.
