乳制品冷链物流的库存-生产策略优化研究

在日益激烈的企业生存竞争中，针对乳制品生产企业如何选取合适的生产批量和库存水平的问题，提出了成本-时间-客户满意度的三目标优化模型。首先，考虑乳制品的库存费用、周转时间和客户满意度，分别建立库存生产成本、库存周转时间和客户满意度优化模型；其次，以生产批量和库存水平为决策变量，应用多目标遗传算法，集成库存生产成本模型、库存周转时间模型和客户满意度模型，求出所有非劣解；最后，应用伪权向量法，通过保质期不同的产品验证提出的模型。结果表明，对于不同保质期的产品，均可得出最优库存生产批量大小和最优库存水平。

Effects of sodium ferulate on the nonenzymatic glycation and oxidation in kidneys of diabetic rats

AIM: To investigate the blocking effects of sodium ferulate (SF) on the nonenzymatic glycation and oxidation in kidneys of diabetic rats. METHODS: The diabetic rats induced by streptozotocin (STZ) were treated with SF (110 mg/kg) per day for 8 weeks. The renal weight/body weight, clearance rate of creatinine (Ccr), proteinuria, advanced glycation end products (AGEs) in renal cortex, and the malonyldialdehyde (MDA), fructosamine (FMN), antioxidant enzymes in serum and renal cortex were measured. The pathologic changes of kidneys were also observed. RESULTS: The levels of Ccr, proteinuria, FMN and AGEs in renal cortex, FMN in serum, and renal weight/body weight in diabetic control group were significantly higher than those in normal control group. In the diabetic control group, there was a highter level of MDA and a lower activity of superoxide dismutase (SOD) and catalase (CAT) in serum and renal cortex than those in normal control group. Except for FMN in renal cortex, the abnormalities were significantly ameliorated in the treatment group. The pathologic changes was significant in the diabetic control group, which was significantly ameliorated with the treatment of SF. CONCLUSIONS: SF protects the activity of antioxidant enzymes, clears away oxygen radicals and inhibits the deposit of AGEs in kindey, which may be the mechanisms of protecting effects of SF on kindey in diabetic rats.     

基于食物安全视角的我国畜产食品进口依赖性风险评价

新时期下,保障我国畜产食品供给安全是保障我国食物安全的重要内容之一,而“适度进口”是保障我国畜产食品供给安全的重要途径之一。如何才算“适度进口”,需对畜产食品进口的相关风险进行分析方可评判。运用进口依赖性评价模型对我国猪肉、鸡肉、羊肉、牛肉、鲜牛奶的进口依赖性风险进行分析发现,上述5种畜产食品均存在进口依赖性风险。其中,猪肉的风险来自美国、德国、丹麦、西班牙和加拿大;鸡肉的风险来自美国、巴西、阿根廷和波兰;羊肉的风险来自澳大利亚、新西兰和乌拉圭;牛肉的风险来自乌拉圭、澳大利亚、新西兰、阿根廷和加拿大;鲜牛奶的风险来自德国、法国、新西兰和澳大利亚。为降低我国畜产食品进口依赖性风险,短期内应采取畜产食品进口市场多元化策略以及用进口饲草料替代进口畜产食品的进口方式;长期应在保障“口粮安全”的前提下,调整农业结构,大力发展草地农业,减少对国际市场的依赖性。     

Effect of sweet potato vines on performance parameters and some carcass characteristics of rabbits

Conventional feedstuffs in Brazil are expensive, which has led to the search for less conventional cheaper and locally available feedstuffs. Thus, this study was carried out to determine the dietary effect of dry sweet potato vines (SPV) on the performance and some carcass characteristics of rabbits. A total of twenty‐seven weaned White New Zealand rabbits (14 male and 13 female) 35 days old with an average initial weight of 755 g were allocated into three treatments. Nine rabbits were assigned to each treatment in a completely randomized design. Three diets were formulated to similar protein and energy levels: 0SPV – diet without inclusion of dry sweet potato vines; 10SPV – diet with 10% alfalfa hay replaced by dry sweet potato vines; and 15SPV – diet with 15% of alfalfa hay replaced by dry sweet potato vines. The experiment lasted for 49 days during which data for feed intake and body weight were recorded. The daily feed intake ranged from 73.17 to 78.02 g; daily weight gain from 22.32 to 23.17 g; feed conversion ratio (FCR) from 3.16 to 3.49 and final live weight ranged from 1839.44 to 1880.55 g. None of the evaluated performance parameters as well as carcass weight, heart weight and percentages of fat and protein in meat were significantly affected by any of the tested dietary treatments. However, the liver weight was statistically lower in animals fed the diets containing 10% of SPV, mainly due to lower glucose content. Glycogen within the tissue, did not differ significantly among treatments. It was therefore concluded that up to 15% of SPV can successfully be included in the diet of rabbits as a cheaper replacement for alfalfa hay without adversely affecting performance.
