Effect of dietary alternative lipid sources on haematological parameters and serum constituents of Heterobranchus longifilis fingerlings

Abstract The worldwide increase in aquaculture production and the decrease of wild fish stocks has made the replacement of fish oil (FO) in aquafeed industry a priority. Therefore, the use of terrestrial animal fats and vegetable oils, which has lower cost and larger supplies, may be good as substitute for FO. This study investigate the effects of total replacement of FO by two terrestrial animal fats (pork lard and poultry fat) and three vegetable oils (palm kernel oil, shea butter oil and s...

Effects of dietary lipid source on growth, digestibility and tissue fatty acid composition of Heterobranchus longifilis fingerlings

AbstractOne of the major problems facing aquaculture is the inadequate supply of fish oil mostly used for fish feed man- ufacturing. The continued growth in aquaculture production cannot depend on this finite feed resources, therefore, it is imperative that cheap and readily available substitutes that do not compromise fish growth and fillet quality be found. To achieve this, a 12-week feeding trial with Heterobranchus longifilis fed diets differing in lipid source was conducted. Diets were s...

The Use of Cassava, Sweet Potato and Cocoyam, and Their By-Products by Non – Ruminants

Abstract As the search for alternative sources of energy for non ruminants continues, this review was undertaken to examine the potential value of cassava (Manihot utilissima Pohl.), sweet potato (Ipomea batatas Poir.), cocoyam (Xanthosoma sagittifolium Schott.) and their by-products as dietary supplements for non ruminants. Studies on these roots and tubers showed that, on a dry-weight basis, contained 2.0 – 7.9% crude protein, 0.3 – 3.1% crude fibre and 72.4 – 77.9% starch. The practi...

Biosecurity

Biosecurity: a veritable tool in livestock production and control of diseases.Biosecurity refers to measures that are taken to stop the spread or introduction of harmful organisms to human, animal and plant life. The measures taken are a combination of processes and systems that have been put in place by bioscience laboratories, customs agents and agricultural managers to prevent the use of dangerous pathogens and toxins

Conservation of Local Genetic Resources: Case of Consumer’s Preference for Indigenous and Exotic Chickens in Abeokuta Metropolis, Ogun State, Nigeria

The study assessed factors determining consumers’ preference for indigenous and exotic strains of chickens. Questionnaire was administered to 150 respondents in Abeokuta Metropolis. The result showed that 29.65% of the respondents made their preference for indigenous chicken strain based on multiple choices of husbandry practices (feeding, health management, and housing). Preference for indigenous strains based on health grounds was 13.60%, while 10.80% had their preference based on housing...
