Department of Commerce: Pork Prices Continue to Fall, While Egg Prices Start to Rise
The data of Commerce Department shows that pork prices, one of agricultural products monitored the Ministry of Commerce on July 25 to 31, are 0.5% lower than the prices in last week (the same below), which was pork prices' continuous price fall for two weeks since the pork prices continued to increase since May. Meanwhile, egg prices continued to rise about 0.8% in last week, which have been rising for 6 weeks. 相似文献

2009年是极不寻常的一年,国际金融危机蔓延对世界经济产生了重大影响。回顾2009年,国内鸡蛋零售价格一波三折,总体是震荡上升的。引起鸡蛋价格波动的原因来自多方面,主要包括饲料成本不断上涨、蛋鸡存栏出现短期变化、季节效应和节日效应明显、突发事件引发短暂剧烈波动等。国际市场方面,美国鸡蛋批发价格上半年受金融危机影响甚大,下半年随着经济形势好转价格回升明显,全年呈现"V"型反弹;加拿大鸡蛋批发价格较为平稳;国际期货市场价格年底大幅跳水。 相似文献

Osiel González Dávila 《Food Security》2010,2(4):383-393
During the period 2006–2008, general inflation around the world was pressed upwards by food inflation. An important reason
for concern about the impact of high food prices arises from the fact that the poorest people spend approximately three quarters
of their income on staple foods. In Mexico, meals are based on maize, with tortillas providing much of the caloric intake
in rural areas. Prices of maize along with nearly every agricultural commodity sharply increased creating a global food price
bubble. Using the Household Income and Expenditure National Survey (Encuesta Nacional de Ingresos y Gastos de los Hogares
ENIGH) conducted in 2006 and 2008, it was found that higher prices for maize affected Mexican household living standards and
food security both in urban and rural areas. There is an evident decay in household living standards from year 2006 to year
2008. In regional terms, urban areas are better off than rural areas. The poorest rural and urban households—net buyers of
maize—were the most affected as their budget share on maize increased significantly. However, higher prices provided direct
benefits to maize producers in rural areas at all levels of living. Another effect of higher maize prices was to redistribute
income towards maize producer households in the middle and bottom of the rural income distribution. 相似文献

This research followed our previous experimental and simulation work on the effect of different teatcup removal settings based on the rolling average milk flowrate and on milking duration at the quarter and udder levels. The aims of this experiment were to (1) quantify the differences in quarter milking duration in a pasture-based automatic milking system and (2) test the effect of increasing the milk flowrate at which teatcups are removed on the last milking quarter on udder milking duration, box time, milk production rate, and somatic cell count (SCC). Milking duration is an important component of efficiency and profitability in conventional and automatic milking systems. Additionally, quarters within an udder have significantly different milk yields and milking durations. This study used data from April to May 2018 of a pasture-based automatic milking system to evaluate quarter milking duration differences between quarters of an udder. Subsequently, we experimentally evaluated the use of 2 percentage-based teatcup removal settings applied to the last milking quarter (i.e., the last quarter with a teatcup still attached) on milking duration, box time, milk production rate, and SCC. The teatcup removal settings were at 30 or 50% of the last quarter's rolling average milk flowrate, while the other quarters remained at the 30% level. The selection of the quarter that would receive the more aggressive teatcup removal setting was determined by identifying the last quarter with a teatcup attached in every milking. Sixty-nine cows were divided into 2 groups that each received 1 of the 2 treatments for a 1-wk period and then switched to the other treatment for a second week. For the months of April and May 2018, quarter milking duration was significantly different between the quarter with the longest and the second longest milking duration within an udder. The quarter with the longest milking duration was milked on average 49 s longer than the quarter with second longest milking duration. However, in 36% of the milkings, the quarter with the longest milking duration was different from that of the previous milking. In the experimental part of this study, we saw no differences in milking duration, box time, milk production rate, or SCC between the 30 and 50% teatcup removal setting applied to the last milking quarter. Further research on using a variation of this percentage-based setting to target the quarter with the average longest milking duration or using an absolute milk flowrate switch-point or a maximum milking duration setting on the last quarter for reducing cow milking duration and box time is warranted. 相似文献

When six cows were milked every 4 h over 48 h the average milk yield per cow increased by 10.7% for the last 24 h period compared with the previous 5 d. Milk composition was similar to pre-experimental values although fat content was 0.5% lower in the last 24 h. The somatic cell count rose to twice the pre-experimental value over the first 24 h but was not significantly different by the second 24 h. It appears that cows responded quickly to an increased frequency of milking and milk of an acceptable composition was produced. This has implications for management of milk production where quotas are in operation and for robotic milking systems. 相似文献
