The utilization of hormone implants and the supplementation of trace minerals have become well adopted management strategies in the feedlot industry. When hormone implants increase rates of growth in feedlot cattle, this could increase the demand for trace minerals to support those rapid rates of growth. In this study, an aggressive implant strategy dramatically increased growth rates and HCW, without having negative effects on marbling score. It was also observed, regardless of hormone implant, trace mineral supplementation tended to increase overall ADG and steers supplemented at industry consultants recommended concentrations had a 33 lb increase in HCW compared to cattle that received no trace mineral supplementation. This would suggest that hormone implants remain a good return on investment and the current national trace mineral recommendations may not be adequate to support the optimum growth finishing beef steers.

The objective of this study was to estimate the impact of a single injection of extended-release eprinomectin on economically relevant production variables in beef cows and calves as well as subsequent feedlot health, performance and carcass traits of calves compared to a traditional, short-duration anthelmintic. Animals from 13 cooperator herds across 7 states were stratified within herd and assigned to 1 of 2 treatments; injectable doramectin (DOR) or injectable extended-release eprinomectin (EPR). There were no differences in pre-weaning cow or calf performance including weight, ADG, reproductive success, or weaning weight. Although EPR cows did have a lower incidence of pinkeye, there were no differences in pinkeye incidence of calves. Fecal samples collected at the start and end of the grazing season indicated a greater reduction in fecal egg counts (FEC) for EPR cows, however, FEC at each timepoint were well below threshold indicative of clinical parasitism. When evaluating feedlot performance, EPR calves tended to have lower incidence of morbidity, however there were no differences in growth performance. When evaluating carcass traits, calves treated with EPR during the pre-weaning phase had a greater marbling score and a greater average quality grade. While there were noted improvements for EPR calves during the feedlot phase including improved morbidity and quality grade, we believe that a lack of parasitic infection during the grazing season may have resulted in a lack of performance differences in this study.

Since 2011, personnel at Iowa State University (ISU) have been engaged with the southeastern European country of the Republic of Kosova (more commonly known as Kosovo). The purpose of this engagement has been to empower Kosovars to transform their agricultural sector so that this newly independent country can reduce its reliance on food imports and develop into a food secure nation. Activities conducted under terms of the international memorandum of cooperation and understanding between ISU and the University of Prishtina (UP) are described in this report. Accomplishments resulting from this partnership include: 1) guest lectures by ISU faculty to UP veterinary students, 2) teaching of workshops and courses by ISU faculty to a global population of students enrolled in UP’s International Summer University 2-week educational program, 3) on-farm consultations with Kosovo dairy farmers, 4) establishment of relationships with livestock-oriented associations in Kosovo, and 5) birth of the first-ever bovine embryo transfer calf in Kosovo. These and other on-going activities are heightening awareness of the need to improve agricultural productivity in Kosovo, particularly in the dairy sector, to stop the flow of euros out of the country for purchase of food that could and should be produced within Kosovo.

Utilization of cover crops as a forage source for the cowherd provides another feed resource at a time when pasture productivity is minimal. However, limited data are available on cover crop utilization by cattle, including cow and calf performance when grazing cover crops. Thus, the objective of this study was to evaluate cow and calf performance while grazing cover crops compared to a traditional, drylot management system of the Beef Teaching fall-calving herd.

Distiller’s dried grains with solubles (DDGS) are a common feedstuff in poultry diets, however, digestibility estimates vary with production method and strain (broiler vs layer). The objective of this study was to determine the amino acid digestibility of 34.1% (as fed) high-protein DDGS in straight-run Cobb 500 broiler chickens. Calculated standardized ileal amino acid digestibility (SIAAD) of indispensable amino acids (AA) ranged from 81.20 to 90.41%. The SIAAD of dispensable AA ranged from 16.16 to 89.78%. The digestibility of limiting AA in HiP DDGS was greater than reported digestibility values of the same AA in DDGS. Additional research is needed to further illustrate the effect of DDGS production on the value of feeding high protein (HiP) DDGS in broiler chickens.
