Change in body weight (BW) and average daily gain were greater in EPR cows compared to CONV treated cows. Pregnancy rates tended to be greater for EPR than CONV cows. Calves from dams treated with EPR were younger at weaning, but had greater weaning weights than calves from CONV dams. Results from this study indicate performance and reproductive advantages for dams treated with EPR as well as possible indirect performance advantages for calves whose dams were treated with EPR.","PeriodicalId":7812,"journal":{"name":"Animal Industry Report","volume":"12 1","pages":"8"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82434757","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}

Five treatments, including 1) control (none added), 2) 100 ppm oregano essential oil, 3) 300 ppm oregano essential oil, 4) 400 ppm oregano essential oil, and 5) 5 ppm butylated hydroxyanisole (BHA), were prepared with ground boneless, skinless chicken breast meat and used for both raw and cooked meat studies. For the raw meat study, samples were individually packaged in oxygen-permeable bags and stored in a cold room (4 ℃) for 7 days. For the cooked meat study, the raw meat samples were vacuum-packaged in oxygen-impermeable vacuum bags and then cooked in-bag to an internal temperature of 75 °C. After cooling to room temperature, the cooked meats were repackaged in new oxygen-permeable bags and then stored at 4 oC for 7 days. Both raw and cooked meats were analyzed for lipid and protein oxidation, volatiles, and color at 0, 3, and 7 days of storage. Oregano essential oil significantly reduced (p < 0.05) lipid and protein oxidation, and improved color stability of raw and cooked meat. However, oregano oil at 400 ppm showed the strongest effect for all these parameters. Hexanal was the major aldehyde detected, which was decreased significantly (P < 0.05) by oregano oil treatment, in cooked meat. Overall, oregano essential oil at 100-400 ppm levels could be a potential replacement for the synthetic antioxidants in chicken meat.","PeriodicalId":7812,"journal":{"name":"Animal Industry Report","volume":"148 1","pages":"7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89036196","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}

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}

To address this issue, solid litter additive (PLT®) at three application rates (i.e., 60.8, 121.6, and 182.4 lb per 1000 ft2) along with spray of EW was tested for NH3 mitigation. The lab-scale study results showed that the three litter additive application rates reduced NH3 generation by 28–79%.

Three grower and finisher diets were formulated to contain low lysine (0.68 and 0.52% standard ileal digestible (SID) lysine), medium lysine (0.79 and 0.60% SID lysine), and high lysine (0.90 and 0.68 % SID lysine) at data recording day (142, 160 and 200 d of age).
