Cooling, transportation and sale processes of spiced geese were studied, eight spiced geese meat samples with different sampling time, Airborne microorganism samples of three different workplaces and five different environmental contact substance samples were test, measures of special mediums, biochemical identification and DNA sequencing were carried out, then Escherichia coli, Yeast, Mildew, Lactic acid bacteria, Staphylococcus aureus and Janthinobacterium were detected. For spiced geese meat samples, microorganisms were significant (p ) increased with the prolong of sampling time. Lactic acid bacteria, Staphylococcus aureus and Janthinobacterium were detected in each processing operation and the total aerobic counts of each sample was increased or significant (p ) increased with the prolong of sampling time;Escherichia coli, Yeast and Mildew were detected on samples entered into the retail outlet mainly and the total aerobic counts of each sample was increased or significant (p ) increased also. In the household workshop, Mildew and Janthinobacterium were the superior microorganisms. In the transport vehicle, Staphylococcus aureus and Janthinobacterium were the superior microorganisms;Staphylococcus aureus was the superior microorganism in the retail outlet. For environmental contact substances, Cooling platform, pallet, chopping block were the most serious contaminated environmental contact substances and the total bacteria counts were significant (p ) more than stainless steel barrel and chopper;Janthinobacterium was the superior microorganism on pallet, stainless steel barrel and chopper;Lactic acid bacteria was the superior microorganism on chopping block and stainless steel barrel;Staphylococcus aureus was the superior microorganism on cooling platform. Findings indicate that Escherichia coli, Yeast, Mildew, Lactic acid bacteria, Staphylococcus aureus, Janthinobacterium were the main microorganisms;Household workshop and the retail outlet were the main place

A study was conducted to determine the effects of feeding sorghum distiller’s dried grains with solubles(SDDGS) on carcasses characteristics(live weight,whole net carcass rate,breast muscle percentage,thigh muscle percentage),muscle quality(meat color,shear stress,cooking loss rate,cooked meat percentage) and meat composition of China Micro Duck(CMD) drakes aged from 4 to 8 weeks.A total of 240 CMD drakes(aged 4 weeks and initial weight were 496.7 g) were randomly allotted to 1 of 4 dietary treatments in randomized complete block *** four treatments were SO(the control group),S5,S10,S15,indicate the dietary content of SDDGS(0,5,10 and 15%,respectively).Each treatment with60 drakes were equally divided into 6 repeated test groups,each group with 10 *** results showed that,on other carcass characteristic and muscle quality indexes of living body weight(BW),whole net carcass yield(WNCY),breast muscle percentage(BMP),breast muscle color(BMC),thigh muscle colo(TMC),breast shear strength(BSS),cooking loss(CD,cooked meat percentage(CMP).For meat composition,the increasing level of SDDGS caused a linear and quadratic decrease(p0.05).Overall,this study revealed that in the three kinds of diets with SDDGS,S5 caused the minimal negative impact on carcass characteristics,muscle quality and meat composition.

作者：张晓春解华东李星景绍红钟正泽重庆市畜牧科学院/农业部养猪科学重点实验室/重庆市养猪工程技术研究中心重庆荣昌402460

In order to study the effect of dietary copper level on blood and tissue copper contents in geese, one-week Sichuan white geese were randomly divided in- to four groups, and the geese in the first, second, third and fourth groups were fed with diet with copper levels of 39.55, 127.60, 194.75 and 255.22 mg/kg, respective- ly. At the ages of 4, 6, 8, 10 and 12 weeks, the contents of copper in blood, liver, chest muscle and subcutaneous fat of the geese were determined. The effects of dietary copper level, age and sex on the blood and tissue copper contents of geese were analyzed by multivariate analysis of variance. The results showed that the di- etary copper level showed no significant effects on the blood and liver copper con- tents of geese （P〉0.05）; the chest muscle copper content of geese in the second group was significantly higher than that in the first group （P〈0.05）; the subcuta- neous fat copper content of geese in the fourth group was significantly higher than those in the other three groups （P〈0.01）; the age had significant effects on the blood, liver, chest muscle and subcutaneous fat copper contents of geese （P〈0.01）; and the sex showed no significant effects on the blood and tissue copper contents of geese （P〉0.05）.

目的挖掘并分析西那卡塞和依特卡肽的不良事件(ADE)信号,为临床安全用药提供参考。方法利用OpenVigil在线工具,收集美国FDA不良事件报告系统数据库2004年1月1日至2023年6月30日的西那卡塞和依特卡肽相关ADE报告,采用贝叶斯置信区间递进神经网络法对重点系统的ADE信号进行检测,并根据《国际医学用语词典》(26.0版)ADE术语集中的首选术语进行编码。结果分别检索到西那卡塞、依特卡肽ADE报告41709、1710份,重点系统阳性信号29、45个,未被药品说明书收录的阳性信号20、36个。低钙血症/血钙降低、血清甲状旁腺素(PTH)异常/血清PTH升高或降低是两药常见的ADE,均被检出;在未被药品说明书收录的信号中,检出了西那卡塞致钙化防御(代谢及营养类疾病)、骨饥饿综合征和高转换型骨病(肌肉骨骼及结缔组织类疾病)等新的中强、强信号,以及依特卡肽致猝死、坏死及治疗无反应(全身及给药部位反应),不稳定型心绞痛、心肌缺血(心脏器官疾病),肠穿孔、胃窦血管扩张、胃溃疡(胃肠道疾病)等新的中强、强信号。结论临床应用两药时,除需关注低钙血症、血清PTH异常等常见ADE外,还应监测一些新的潜在的ADE信号,如西那卡塞致骨饥饿综合征、钙化防御、心室疾病等,依特卡肽致猝死、心肌缺血、不稳定型心绞痛、肠穿孔及胃溃疡等;当出现新的ADE时,临床应及时评估患者的治疗获益与风险,更新治疗方案和药学监护计划,以保障患者用药安全。

本试验旨在研究日粮消化能(DE)和真可消化赖氨酸(true digestible Lys)含量对初产母猪妊娠前期(配种～妊娠第84天)生产性能、妊娠物组成和血液激素水平的影响,得出初产母猪妊娠前期能量和赖氨酸的适宜需要量。试验采取二因子(DE和true digestible Lys)4水平饱和D-最优回归设计,选取7～8月龄、体重为(123.26±5.69)kg的渝荣Ⅰ号CB系后备母猪36头,随机分为6组,每组6个重复,每个重复1头猪。单栏限喂饲养,分别饲以6种不同DE和真可消化赖氨酸水平的日粮,试验期84 d。试验结果显示:母猪妊娠前期,随着DE水平和真可消化赖氨酸水平的提高,母体增重有增加的趋势;提高DE水平显著降低母猪妊娠第84天时的活仔数(P0.05);妊娠前期母猪血清中孕酮含量随DE水平的提高而降低,胰岛素含量随DE水平的提高而增加,DE和真可消化赖氨酸水平不会对血清中促黄体素的浓度产生影响(P>0.05)。研究结果提示:为提高初产母猪的窝重,妊娠前期日粮中DE和真可消化赖氨酸的推荐含量为12.50MJ/kg和0.69%。
