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}
