MEKARN Conference 2010
The experiments were conducted in three farms and Station of Ninh Binh Rabbit Breeding in a period of 16 months with 3 subjects (i) Methodologies for processing organic manure from Tithonia foliages with and without addition of 1% phosphorus and 0.5% lime and materials were mixed, pressed and covered by plastic and soil keeping in aerobic condition for 4 months, (ii) Tithonia compost used as manure supplying for planting Mulberry and Kudzu with an amount of 15 tonnes Rabbit manure containing 342 kg crude protein/ha/year as standard nitrogen level and (iii) Tithonia foliages used as supplement for feeding growing rabbits in Vietnam. .
The results showed that: compost made from Tithonia green foliages with addition of 1% phosphorus and 0.5% lime contain 2.17 % of crude protein and high percentages of phosphorus (1.36%) and potassium (2.36%) to compare with Rabbit manure and Goat manure. Organic matter of the soil was improved by supply of compost made from Tithonia foliages (2.74%, 1.56% and 1.75%). Contents of Phosphorus (0.37%, 0.18% and 0.16%) and Potasium (1.15%, 0.67% and 0.58%) in the soil after planting 16 months of planting foliage plants were improved for Tithonia compost, Goat manure and Rabbit manure, respectively. Edible biomass yield of Mulbery were in the range of 64.5, 55.2 and 53.1 tonnes/ha/year and for Kudzu 35.2, 30.8 and 30.2 using Rabbit manure, Goat manure and Tithonia compost, respectively. Intake of growing rabbit was 73g, 69g and 67g/day and liveweight gain was 29g, 25g and 23g/day when feeding foliages of Mulbbery, Kudzu and Tithonia as supplementation for based diet of guinea grass and concentrate
