feedstuff intake plays key role in impacting the yield and quality of milk. In this study, we discussed the contents of trace metal elements in cow milk impacted by different feedstuffs. We detected the contents of Pb, Cd, As, Cu, Mg, Ca, Fe and Zn in different feedstuffs and milk by atomic absorption spectrophotometry. The determinations of Pb, Cd and As contents were by graphite furnace A_AS and Cu, Mg, Ca, Fe and Zn was by flame atomic absorption spectrometry. The results showed that Pb, Cd, As and Cu presented in feedstuffs, but Pb, Cd and As were lowly detected in milk samples, and Cu was not detected in milk samples. The content of Mg in concentrates was lower than that in forages. However, the content of Mg in milk from concentrate feed was higher than that in forage feed. This suggested that the utilization of Mg in concentrate feed was higher than that in forage feed. The contents of Ca and Zn were opposite to Mg, and the utilization of Ca and Zn in forage feed was higher than that in concentrate feed. There was no obviously change law of Fe in different feedstuffs and milk samples. The relationship between the contents of trace metal elements in milk to feedstuffs would provide a theoretical basis for dairy farming. It would be useful for improving the milk yield and milk quality of dairy production.

Open Journal of Animal Sciences 2011年第3期1卷 106-111页

Sun-dried blend of maize offal and blood (SDMBM) was analyzed and its effect on the per- formance of broiler chickens (Anak-2000 strain) evaluated. Fresh blood prevented from coagu- lation, mixed with maize offal, was sun-dried, ground, mixed again with blood and ground into a meal after drying again. The crude protein, fat, fibre, ash, ADF and gross energy contents of SDMBM were, 362.0, 45.5, 31.8, 69.3, 52.3 g/kg DM and 4.245 kcal/g, respectively. It was ade- quate in all essential amino acids for growing broiler chickens except methionine. Eighty 14- day-old commercial broiler chicks were ran- domly allocated to four dietary treatments (fed ad libitum;four replicates each) consisting the control diet (0 g SDMBM/kg diet), which con- tained fishmeal, groundnut cake and soybean meal, and three other diets (50, 100 and 150 g SDMBM/kg diet). In a feeding trial, the starter (14 to 35 d) and finisher (35 to 49 d) dietary treat- ments did not have significant impact (P > 0.05) on body weight gain, efficiency of feed conver- sion, mortality and final body weights. The con- trol diet was inferior (P < 0.05) to 50, 100 and 150 g SDMBM/kg diets for feed cost per unit weight gain in the starter phase, 100 g SDMBM/kg diet in the finisher phase, and 100 and 150 g SDMBM/ kg diets for the whole period (14 to 49 d). Overall, the 100 and 150 g superior (P < 0.05) to the con- trol diet in cost of production per unit weight gain and all the SDMBM diets greater than con- trol in economic benefit per unit weight gain. Results suggest that dietary SDMBM up to 150 g/kg diet has a positive effect on broiler per- formance and can totally replace more expen- sive fishmeal.
