effect of cow dung on fish growth

1001, Omu-Aran, Kwara State, Nigeria. The milking cow dung was found to have significantly (P<0.05)) highest pH value than the heifer dung. Cow manure has long been used as a fertilizer for crops and gardens. Cow dung is found to be an effective source of organic fertilization, which positively influences the growth performance of major carps in respect of fish production [11]. Effect of cow dung on soil physical properties, growth and yield of maize (Zea mays) in a tropical Alfisol Adekiya AO1*, Ojeniyi SO2, Owonifari OE2 1. Runoff from manure increases nitrogen and phosphorus levels in waterways, causing explosions of algae growth that can lead to fish and plant die off, even to the point of creating aquatic dead zones. The design used was a factorial randomized block design (RBD), which consisted of 2 factors: factor I: cow manure and factor II: growth stimulant (atonic). The grow out period was 60 days. the influence of cow urine on growth of C. mrigala is significant. 2. the N-total in the soil. Effects of Cow dung and N. P.K Fertilizer at different levels on the Growth performance and Nutrient Composition of Moringa oleifera Anamayi S. E.1, Oladele O. N.2, Suleiman R. A.2, Oloyede E. O.2 and Yahaya U.2* 1Federal College of Forestry Mechanization, Afaka, Kaduna 2Trial Afforestation Research Station, Forestry Research Institute of Nigeria The experiment was conducted to study the effect of different rates of cow dung application on growth and yield of carrots (Daucus carrota L.) of Nantes variety during 2015 at Ambo University College of Agriculture and Veterinary Sciences. The effects of five (5 000, 10 000, 15 000, 20 000, 24 000 kg ha −1 year −1) different doses of organic fertilizer (cow dung) were studied on pond productivity in terms of plankton production and fish biomass in freshwater fish ponds.The grow out period was 60 days. Physico‐chemical factors of pond waters were also monitored. Physico‐chemical factors of … The experimental results showed that pig, cow and chicken manure loaded in the fish pond can directly or indirectly serve as nutritive sources for growth of silver carp, bighead carp, common carp and tilapia. Cow dung were applied at four levels; T1 (control), T2 (5 t ha-1), T3 (10 t ha-1) and T4 (15 t ha-1). The pH of heifer and cow dung was 7.24±0.17 and 8.19±0.18 respectively. Present values were higher pH in lactating cow and heifer dung The pH of heifer and lactating cow dung of experimental animal is presented in Table 4.1. When cow manure is added to the soil, it infl uences the process of mineralization, producing nitrate (NO 3) and ammonium (NH 4) for plant growth (Sun-Table 1. Department of Crop and Soil Sciences, Landmark University, P.M.B. The effects of five (5 000, 10 000, 15 000, 20 000, 24 000 kg ha−1 year−1) different doses of organic fertilizer (cow dung) were studied on pond productivity in terms of plankton production and fish biomass in freshwater fish ponds. An idle fish pond, an endless supply of cattle dung and curiosity that launched a research project on new fodder for simple, low-cost and profitable fish cultivation have shown satisfying results. The effect of manure on the fish growth is not only determined by its chemical composition but also by its freshness (Merkel, 1981).
