Agricultural lenders in the six Northwest Iowa counties serve over 100 dairymen, representing production from over 57,000 cows. Add to that Siouxland producers in the surrounding states and the numbers double. A review of programing for dairy lenders in Siouxland found that little programing had been directed to dairy lenders specifically in recent years. With the stresses of low milk prices, variable feed prices and high land prices, lenders were often using dated budgets and formulas to evaluate profitability of dairy enterprises. A Dairy Lenders Seminar for the Siouxland area was developed based on the Tri- State Lenders Conference (IA, IL, WI) as a template, conducted and evaluated in November 2017. 41 lenders came from four states, representing 14 lending institutions plus four other industries. From those that returned program evaluations their attendance translated to 65 dairies, 69,725 milking cows and 97,400 acres producing feed for those cows. Overall, 88 percent of respondents were mostly, or completely satisfied with the activity and 100 percent would recommend the activity to others. In addition, 65 percent anticipated benefiting economically as a direct result of what they learned from this Extension activity. When asked about the presenters, 100 percent were mostly or completely satisfied with their knowledge and responses to questions. Over 73 percent of the lenders indicated that one or more of their clients planned on expanding their herds; Fourteen percent predicted at least one of their clients would exit the industry; and 17 percent believed that one or more of their clients would add robotic milkers to their operations. We evaluated increase in the level of understanding and found that the highest change was in the understanding comparing profitability of conventional, organic and grazing dairies at 88 percent. Next, was dairy component markets and how it affects farm-gate prices plus the information on analyzing enterprises for profitability, both at 55 percent. Finally, plans to adopt a practice or technology as the result of a program is the truest measure of success for Extension programs, with 100 percent of respondents indicating the commodity market updates would be most likely. Overall, this initial Siouxland Dairy lenders Seminar was highly successful and will be held annually in the future.
爱荷华州西北部六个县的农业贷款机构为100多名奶牛场场主提供服务，代表着57,000多头奶牛的产量。再加上周边各州的苏州生产商，这个数字翻了一番。对苏克兰乳制品贷款机构规划的审查发现，近年来专门针对乳制品贷款机构的规划很少。在低牛奶价格、多变的饲料价格和高土地价格的压力下，贷款机构经常使用过时的预算和公式来评估乳制品企业的盈利能力。2017年11月，Siouxland地区以三州贷款机构会议(IA, IL, WI)为模板举办了乳品贷款机构研讨会，并进行了评估。41家贷款机构来自4个州，代表14家贷款机构和4个其他行业。从那些返回项目评估的人那里，他们的参与转化为65个奶牛场，69,725头奶牛和97400英亩的土地为这些奶牛生产饲料。总体而言，88%的受访者对该活动非常满意或完全满意，100%的受访者会向他人推荐该活动。此外，65%的受访者预计，他们从这项推广活动中学到的知识将直接带来经济效益。当被问及演讲者时，100%的人对他们的知识和对问题的回答基本或完全满意。超过73%的贷款人表示，他们的一个或多个客户计划扩大他们的畜群;14%的人预测，他们的客户中至少有一个会退出这个行业;17%的人认为，他们的一个或多个客户会在他们的业务中添加机器人挤奶机。我们评估了理解水平的提高，发现最大的变化是对传统、有机和放牧奶牛场的盈利能力的理解，分别为88%。其次是乳制品成分市场及其对农场价格的影响，以及分析企业盈利能力的信息，两者都占55%。最后，计划采用一种实践或技术作为一个项目的结果是推广项目成功的最真实的衡量标准，100%的受访者表示商品市场更新是最有可能的。总的来说，最初的Siouxland乳业贷款人研讨会非常成功，未来将每年举行一次。

Changes to the production method of distiller’s dried grains with solubles (DDGS), a common feedstuff in poultry diets, can alter the nutrient profile and energy content. Estimates of DDGS digestibility vary as a result of the altered production method, removal of value-added products like distiller’s corn oil, as well as the strain of chicken used (broiler vs. layer). The objective of this study was to determine the energy digestibility of high protein DDGS (HiP DDGS) fed to straight-run Cobb 500 broiler chickens. The apparent nitrogen-corrected metabolizable energy of HiP DDGS was calculated at 2,710 kcal/kg. Additional research is needed to further illustrate the influence of production method on HiP DDGS feeding value in broiler chickens.

This study evaluated the effect of extended-release eprinomectin on production parameters and reproductive success of yearling fall replacement heifers. Heifers were treated with an ivermectin (CONV) or an injectable extended-release eprinomectin (EPR). There were no differences between treatments at initial body weight (BW). However, subsequent body weights taken 7 months and 12-months post-treatment demonstrated heavier body weight, greater overall weight gain and a greater average daily gain for heifers treated with EPR. Heifers treated with EPR had greater pregnancy rates to AI and greater overall pregnancy rates than CONV. Also, a greater proportion of EPR heifers calved in the first 21 days of the subsequent calving season. Results from this study indicate improved performance and greater reproductive success for replacement heifers treated with extended-release eprinomectin.

Implications Hot temperatures negatively impact global livestock production and are a serious financial burden to pig producers. Trends predict that global temperatures will continue to increase, making this a pertinent issue now and in the future. Study objectives were to investigate the effects of genetics and dietary fiber content on growth, feed intake, and feed conversion efficiency in response to repeated exposure to heat stress. A total of 103 finishing barrows from a contemporary commercial line and Yorkshire lines divergently selected for high and low feed efficiency based on residual feed intake ( RFI ) were used in this experiment. All pigs were subjected three consecutive times to a 4-d heat stress ( HS ) load, starting with a 19-d thermal neutral ( TN ) adaptation period and alternated by 7-d TN conditions (see Figure 1). Feed intake, growth and feed conversion efficiency were measured for each period. Heat stress negatively impacted all three production traits, however, pigs from the commercial line were most affected. In addition, during heat stress, pigs from the low RFI (= more efficient) line lost their advantage in feed conversion efficiency over pigs from the high RFI line. This supports the hypothesis that pigs with a high genetic propensity for lean tissue accretion are more susceptible to heat stress. However, our results also indicated that the effect of heat stress on feed intake, growth rate, and feed conversion efficiency was not significantly influenced by the amount of fiber in the diet (at constant energy density).
高温对全球畜牧业生产产生负面影响，对养猪生产者造成严重的经济负担。趋势预测，全球气温将继续上升，这使其成为现在和未来的一个相关问题。本研究旨在探讨遗传和饲粮纤维含量对反复热应激下肉鸡生长、采食量和饲料转化率的影响。本试验选用现代商品品系和约克郡品系的103头育肥猪，根据剩余采食量(RFI)分别选择高、低饲料效率。所有猪连续3次接受4 d热应激负荷，从19 d热中性(TN)适应期开始，交替进行7 d TN适应期(见图1)。每个阶段测量采食量、生长和饲料转化率。热应激对所有三个生产性状都有负面影响，但商品品系的猪受影响最大。此外，在热应激期间，来自低RFI(更高效率)品系的猪在饲料转化效率方面失去了来自高RFI品系的猪的优势。这支持了一个假设，即瘦肉组织增加的高遗传倾向的猪更容易受到热应激的影响。然而，我们的结果也表明，热应激对采食量、生长率和饲料转化率的影响不受日粮中纤维含量的显著影响(在恒定能量密度下)。
