Research Of The Nutrition Requiment Of Energy And Protein And Calcium In Landaise Geese

Two stage experiments were conducted to study the influence of different dietary energy(ME) and crude protein(CP) and calcium(Ca) on growth performance and carcass quality and feed conversion and small intestinal feature and blood biochemical parameters in green goose(l-28 days old) and gosling(33-68 days old). The orthogonal 3 3 factorial trial were selected and 9 dietary were designed to explore the best level of dietary metabolizable energy and crude protein and calcium.Research of the nutrition demand of energy and protein and calcium in green landaise gooseThis period studied the effects of dietary energy and crude protein and calcium level on growth performance and carcass quality and feed conversion and small intestinal feature and blood biochemical parameters in green goose. 216 one-day-old Landaise were allotted to 9 dietary treatments. Each group of 24 geese has 2 replicates. The orthogonal 3 3 factorial trial involves dietary metabolizable energy(ME), crude protein(CP) and calcium(Ca:P= 1.75:1) at three levels to study their effects on green Landaise geese. The dietary metabolizable energy(ME) were 11.92MJ/Kg, 12.45MJ/Kg, 12.97MJ/Kg; the crude protein levels were 19.00%, 20.00%, 21.00%; the calcium levels were 0.80%, 0.95% and 1.10%.The results of this experiment show that metabolizable energy and crude protein and calcium levels in me diet and energy-protein interaction had significant effects(P<0.01) on the performance and the ratio of intake to gain of green geese; metabolizable energy levels had significant effects(P<0.01) on average daily gain, while others dose not(P>0.05); dietary metabolizable energy also had significant effects(P<0.01) on the ratio of abdominal fat and the efficiency of energy; calcium levels had significant effects(P<0.05) on the efficiency of calcium; metabolizable energy had significant effects(P<0.01) on urea nitrogenous and uric acid in serum, the highter dietary metabolizable energy level, the lower urea nitrogenous and uric acid in serum, contrary, dietary crude protein level had significant effects(P<0.05) on urea nitrogenous and uric acid in serum, the highter crude protein level, the highter urea nitrogenous and uric acid in serum; energy - protein interaction had significant effects(P<0.05) on the active of alkaline phosphatatase in serum; calcium levels had significant effects(P<0.01) on the content of ash and calcium in tibiae, energy and protein levels had significant effects(P<0.05) on the content of calcium in tibiae; metabolizable energy and crude protein and calcium levels in the diet and energy-protein interaction had no significanteffects(P>0.05) on small intestinal villus and gland's and mucous membrane proper, comparing all quotas, in the condition of this experiment, the best level of metabolizable energy and crude protein and calcium in green landaise goose diet can be : metabolizable energy 12.97MJ/Kg, crude protein 19.00%, calcium 1.10%.Research of the nutrition demand of energy and protein and calcium in landaise goslingThis period studied the effects of dietary energy and crude protein and calcium level on growth performance and carcass quality and feed conversion and small intestinal feature and blood biochemical parameters in gosling. 144 28-day-old Landaise gosling were allotted to 9 dietary treatments. Each group of 16 geese has 2 replicates. The orthogonal 3 3 factorial trial involves dietary metabolizable energy(ME), crude protein(CP) and calcium(Ca:P=1.75:l) at three levels to study their effects on Landaise gosling. The dietary metabolizable energy(ME) were 11.92MJ/Kg, 12.45MJ/Kg, 12.97MJ/Kg; the crude protein levels were 16.00%, 17.50%, 19.00%; the calcium levels were 0.70%, 0.85% and 1.00%.The results of this experiment show that metabolizable energy and crude protein and calcium levels in the diet had significant effects(P<0.01) on the performance of gosling, while energy -protein interaction dose not(P>0.05); metabolizable energy and crude protein levels had significant effects(P<0.01) on daily intake, also dose calcium level...
