{"title":"Siouxland Dairy Lenders Seminar Focus OnDairy Enterprise Issues","authors":"F. M. Hall, Larry F. Tranel","doi":"10.31274/ANS_AIR-180814-387","DOIUrl":"https://doi.org/10.31274/ANS_AIR-180814-387","url":null,"abstract":"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.","PeriodicalId":7812,"journal":{"name":"Animal Industry Report","volume":"62 1","pages":"44"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84274229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":7812,"journal":{"name":"Animal Industry Report","volume":"1 1","pages":"55"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91257062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":7812,"journal":{"name":"Animal Industry Report","volume":"49 1","pages":"9"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88476435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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).","PeriodicalId":7812,"journal":{"name":"Animal Industry Report","volume":"34 1","pages":"67"},"PeriodicalIF":0.0,"publicationDate":"2017-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74953210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
