TY - JOUR ID - TI - Effect Of Replacing Calcium Powder By Limestone On The Economic Feasibility Study Of Fattening Iraqi Calves Project AU - Y.M.Kassim PY - 2014 VL - 6 IS - 2 SP - 70 EP - 82 JO - Kufa Journal for Agricultural Sciences مجلة الكوفة للعلوم الزراعية SN - 20727798 23128186 AB - In order to arrive at higher revenue and achieve high profitability earnings benefit ofinterested breeders and researchers. This study was conducted in the private farm (Bartala station for Animal Production) in Nineveh province. Twenty-four (males) calves (Aljenobi strain) with aged 8-9 months were fed four fattening diets similar level ofcrud protein and energy metabolize but different in level ofcalcium in fattening diets. Animals got roughage feed by daily grazing for a six hours per day until final fattening experiment (120 days).The average initial weight ofcalves were 115.500, 115.330, 115.833, 115.166 kg respectively. Calves were distributed randomly into four treatments (0, 0.50, 1.00, 1.50% calcium powder) six calves for each treatments. The results showed an improvement in average ofweight gains for the last three treatments compared to the first treatment (control diet) and an increase in amount offeed intake as calcium level increased. Also the results showed a presence ofa slight mathematical increase in total cost ofthe fattening process by increasing calcium levels. The average total cost were 4.880.200,5.058.344,5.177.908,5.275.332 Iraqi diners for four treatments respectively. While the results ofthis study indicated revenues to achieve profitability by high percent when increasing calcium levels from 0% in the first treatment to 0.5,1 and 1.5% levels in experimental fattening diets ofcalves during fattening experience period where total income received for fattening project to 3.855.800,4.237.336,4.844.852,5.044.668 Iraqi dinars for four treatments respectively. This increase in revenue fattening experience has contributed positively to maximize the percentage ofnet profit in revenues offattening farm to 79.01,83.77,93.57,95.63% for four treatments respectively.
