Published: October 2022

Abstract
Past research has provided the groundwork into determining the impact of daily activity, elevation, and slope on energetic requirements for rangeland cattle. However, there is not a consensus on how to accurately account for this dynamic. Thus, the objectives of this study were to 1) calculate rolling and roughness index and distance traveled respective of elevation change and 2) create a regression analysis from objective 1 and determine differences in precision between the two methods for determining changes in NEmract. This analysis compared two methods to estimate the energetic costs of travel on elevation and slope on net energy for activity (NEmract). The analysis was conducted from a dataset consisting of six herds of yearling steers (n = 127) that grazed native summer pastures from May to August in 2021 at the Cottonwood Field Station (Philip, SD). Pastures were composed primarily of native C3 grasses, Nassella viridula and Pascopyrum smithii, and C4 grasses, Bouteloua gracilis and Buchloe dactyloides. VenceTM collars were set to record GPS fixes at 5-minute intervals. GPS data was coupled with real time weight data collected from Smart Scales (C-Lock Inc, Rapid City, SD) located at the stock tanks within six pastures at three different stocking rates treatments (n = 3, 2 reps per trt). The combination of weight and GPS data allowed for the quantification of how elevation, slope, and daily distance traveled impacted NEmract. The first method to account for daily travel is a quantification of terrain use. This method has two indexes, a roughness index and rolling index, to determine the impact of terrain on grazing distribution. Roughness index is a measure of slope and elevation of an individual animal in comparison to the herd. The rolling index quantifies animal distribution by accounting for distance from water. The second method calculated the distance and elevation changes between successive GPS fixes for individual animals over the course of the summer grazing period. The linear regression was conducted in Program R (P &lt; 0.05) which regressed NEmr plus NEmract calculated using the two methods against back-calculated to NEmr using daily body weight and forage nutrient composition (TDN). The result of this analysis provides levels of precision for different methods when quantifying the daily distance traveled, of steers relative to horizontal and ascending locomotion helping to evaluate trade-offs based on available GPS data (e.g., 5 minutes versus 1 hour recording intervals). Technological advances have allowed unprecedented data collection on individual animals. Results from this study will help refine energetic equations on extensive rangeland systems which is important due to the inherently large travels distances on these production settings.

Abstract
Heifer pregnancy (HPG) is lowly heritable, yet economically relevant in beef cattle production systems. Hence, identifying single nucleotide polymorphisms (SNP) associated with phenotype could increase the amount of information used in the genetic evaluation of the trait. Using RNA-sequence data from lactating Holstein cows, a set of SNP (n = 69) were discovered among embryo mortality conceptuses (Conceptus-SNP) associated with maternal recognition of pregnancy on day 16 after artificial insemination (AI). To further study these SNP, our objective was to conduct analyses to identify markers associated with HPG in Red Angus. Phenotypic records and genotypes were provided by the Red Angus Association of America (RAAA). For phenotypes, a total of 59,387 cattle records, from the June 2022 RAAA genetic evaluation, were used in the analysis. For genotype data, a 47,860 SNP panel (excluding SNP on the X-chromosome) were formed by combining the historical RAAA genotype data (96,162 animals with genotypes) and genotypes from whole genome sequence of 30 prominent Red Angus AI sires. Markers were mapped to the ARS-UCD1.2 bovine reference genome and then imputed to 47,860 SNP panel using findhap software. A subset of SNP (n = 2,169 SNP; Conceptus-SNP and the multi-breed selected reduced panel [MSRP]) were extracted from the imputed genotypes file. Using PLINK software, genotype quality control procedure was performed so that animals with call rate &lt; 0.9 were removed. A marker was removed if: it had minor allele frequency &lt; 0.01, not in Hardy–Weinberg equilibrium (P &lt; 0.00001), or in high linkage disequilibrium (r2 &gt; 0.95). The final genotype file contained 96,667 animals with 2,137 SNP. A Bayes Cπ single-step super hybrid model (π = 0.99), using the BOLT software package, was used to estimate marker’s posterior probability of inclusion (PPI), the marker significance criterion in predicting HPG. A marker’s PPI was calculated as the average probability from four different Gibbs sampling chains of 75,000 iterations that included 5,000 iterations as burn-in. Markers rs42576394 (18:60583784) and rs42942055 (14:34249373) had PPI of 25.5 and 7.1%, respectively; suggesting association with HPG. None of the Conceptus-SNP had a detectable association with HPG; however, these Conceptus-SNP may be much more informative for genotype to phenotype association analyses for the trait of stayability. Such a trait would be measured with lactating mature beef cows and potentially more similar to the lactating Holstein cows from which the markers were discovered.
PSIII-6 Late-Breaking: Ground Hybrid Rye as a Partial or Sole Concentrate in Backgrounding Rations
Authors: Tobin Colin , Carlson Zachary , Swanson Kendall C , Hoppe Karl 
Published: October 2022

Abstract
Cereal rye has been utilized in multiple ways within cropping systems in the northern Great Plains. Rye has traditionally not been utilized as a suitable grain for growing and finishing calves. Previously, recommendations have limited the use of rye due to the negative effects of ergot ingestion. Recent hybrid rye germplasms have shown increased yields with decreased incidence of ergot. The aim of this study was to determine the effects of ground hybrid rye inclusion rate on dry matter intake (DMI), growth performance, and feed efficiency in backgrounding beef steers. Two hundred crossbred steers were shipped to the Carrington Research Extension Center near Carrington, ND, stratified by weight, and assigned to one of twenty pens (n = 10 steers/pen). Four treatments were used in a completely randomized block design to evaluate animal performance during backgrounding when fed partial or complete replacement of corn with rye as the concentrate source. Ground hybrid rye was substituted for DRC as follows: a basal diet formulated with 20% DRC: 0% ground hybrid rye (CON), 13.5% DRC: 6.5% ground hybrid rye (RYE1), 6.5% DRC: 13.5% ground hybrid rye (RYE2), or 0% DRC:20% ground hybrid rye (RYE3) on a dry matter basis. Steers were fed for a total of 56 days beginning Oct. 25, 2021. Interim weights were taken on Nov. 22, 2021, and final weights were taken Dec. 20, 2021. At the conclusion of the feeding period, cattle were weighed on two consecutive days to determine final body weight. Performance data including animal live weights, ADG, DMI and G:F ratio were calculated. The use of rye within the diet did not influence steer weight throughout the study (P = 0.11). No differences in ADG were detected throughout the study (P = 0.68). Steers fed diets containing hybrid rye had higher DMI (P = 0.03) and higher F:G (P = 0.04) during the first month of the study. Increased DMI during the initial month of backgrounding may promote improved intake and growth. Results from the study suggest that steers fed rye as a partial or sole grain in a high forage backgrounding diet weighed similar to calves fed corn as the sole concentrate source.

Abstract
Optimizing reproductive efficiency is crucial in sustaining a successful cattle operation. However, optimizing reproductive performance in young range beef cows is often not captured due to an inability to meet the increased physiological demands. The objective of this study was to determine the impact of feed additives on reproductive performance, cow body weight (BW), body condition score (BCS), and calf growth in young, range beef cows. Data were collected from 2- and 3-year-old range cows (n = 189) from the March-calving herd at the University of Nebraska Gudmundsen Sandhills Laboratory (GSL) located near Whitman, NE over a three-year period (2019-2021). Cows were individually supplemented 908 g/d with one of two 30% crude protein supplement treatments with the addition of either: 1) 160 mg·cow-1·d-1 of rumensin (MON; Elanco Animal Health) or 2) 40 g·cow-1·d-1 of propionate salt (CAP; NutroCal 100; Kemin Animal Nutrition and Health). Supplementation was initiated approximately 7 d after calving and continued for an average of 70 d. Cow BW and BCS were collected weekly from calving to the start of breeding and then again at weaning. On approximately d 60 postpartum, milk production was measured by a modified weigh-suckle-weight technique. Cows were exposed to fertile bulls for a 45-d breeding season starting in June of each year. Cow BW (P ≥ 0.19) and BCS (P ≥ 0.11) were not affected by postpartum supplementation during the study. However, cows receiving CAP did lose more BW (P = 0.04; -7 vs -2 kg for CAP and MON; respectively) from calving to breeding than their counterpart. Calf BW at birth, weaning, or 205-d weight were not impacted (P ≥ 0.68) by the postpartum supplementation strategy. Twenty-four-hour milk production and milk components (fat, solids-non-fat, urea nitrogen) were not influenced (P &gt; 0.21) by postpartum supplementation strategy. However, cows receiving CAP supplement had an increase (P = 0.04; 5.40 vs 5.31% for CAP and MON; respectively) in milk lactose percentage and tended (P = 0.06; 2.56 vs 2.68% for CAP and MON; respectively) to have lower milk protein percentage than their counterpart. Cows receiving CAP supplementation had an increase (P = 0.04; 89 vs 80% for CAP and MON; respectively) in overall pregnancy rate. This study implies that young postpartum cows fed additional glucogenic precursors in the form of propionate salts may increase reproductive efficiency without impacting a change in body weight or body condition score.
Doing Family over Time: The Multilayered and Multitemporal Nature of Intergenerational Caring through Consumption
Authors: Kastarinen Anne , Närvänen Elina , Valtonen Anu 
Published: October 2022

Abstract
Care is a central dimension of family consumption. Previous studies have explored it as interpersonal, emotional work performed through everyday consumption practices. Most of these studies have investigated care as articulated in the present time and within nuclear families. This study sets out to explore the relations between grandparents and grandchildren, arguing that it provides an intriguing case for enriching the current understanding of care in family consumption and its multitemporal nature. To this aim, the study conducts qualitative interviews and employs a narrative version of the theory of generativity to conceptualize the multifaceted ways in which caring manifests through consumption in grandparent–grandchild relations. As a result, the study offers a processual framework of intergenerational caring through consumption (ICTC). The analysis identifies, first, the multilayered nature of ICTC, consisting of three layers of caring enacted through generative acts. Second, it identifies three temporal perspectives to ICTC, revealing its multitemporal nature. The framework provides novel insights into how familial caring is done from generation to generation, and how a desire to care is kept alive in today’s consumer society.
Susceptibility of ‘Malama’ Avocados to Bactrocera dorsalis (Diptera: Tephritidae) in Hawai’i and a Proposed Systems Approach for Market Access
Authors: Follett Peter A , Asmus Glenn , Hamilton Lindsey , Stockton Dara 
Published: October 2022

Abstract
Avocados are generally poor hosts or nonhosts for tephritid fruit flies, which can influence the type of mitigation measures required by export protocols for trade. We conducted experiments to determine the susceptibility of the avocado, Persea americana, cv. ‘Malama’ to infestation by Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), in Hawai’i using laboratory and field no-choice cage tests, together with field sampling. In no-choice cage tests, infestation rates increased with decreasing fruit firmness over time after harvest. Although risk of infestation was negatively correlated with fruit firmness, about 50% of mature hard fruit exposed immediately after harvest became infested. In field cage tests, mature hard fruit on the tree at the 25% purple color stage were not infested, whereas fruit at the 50, 75, and 100% purple color stages were infested at relatively low rates. Field sampling of fallen ‘Malama’ fruit over two seasons showed no natural infestation by B. dorsalis and trap captures in avocado orchards using McPhail traps containing protein bait lures averaged 0.13 ± 0.03 (mean ± SE) flies per trap per week, underscoring the low prevalence of fruit flies in avocado orchards and the poor host quality of this cultivar. A systems approach based on poor host status, low prevalence, and a limited harvest period (October to March) and distribution area (northern tier states) is proposed to export ‘Malama’ avocados from Hawai’i to the continental United States.
Impact of Citricola Scale Coccus pseudomagnoliarum (Hemiptera: Coccidae) on Valencia Orange, Citrus sinensis Production and Fruit Quality

Published: October 2022

Abstract
Citricola scale, [Coccus pseudomagnoliarum (Kuwana)], is a key pest of citrus requiring insecticide control in areas where biological control is ineffective. Here we quantified the relationship between C. pseudomagnoliarum density and Valencia orange (Citrus sinensis L. Osbeck) yield and sooty mold contamination to inform pest action thresholds. Two field experiments documented significant effects of adult or nymphal C. pseudomagnoliarum densities on fruit yield and sooty mold. Adults generally had more pronounced effects, reducing average tree yield by up to 43% and increasing sooty mold prevalence by at least 45%. Analyses estimated significant effects of C. pseudomagnoliarum at densities less than 0.1 adults/branch or 1.0 nymph/leaf. These results suggest a decrease in the current threshold of 1.0 for adults/branch and may be warranted to minimize C. pseudomagnoliarum damage.

ABSTRACTUnderstanding how certain animals are capable of regenerating their hearts will provide much needed insights into how this process can be induced in humans in order to reverse the damage caused by myocardial infarction. Currently, it is becoming increasingly evident that cardiac interstitial cells play crucial roles during cardiac regeneration. To understand how interstitial cells behave during this process, we performed single-cell RNA sequencing of regenerating zebrafish hearts. Using a combination of immunohistochemistry, chemical inhibition, and novel transgenic animals, we were able to investigate the role of cell type-specific mechanisms during cardiac regeneration. This approach allowed us to identify a number of important regenerative processes within the interstitial cell populations. Here, we provide detailed insight into how interstitial cells behave during cardiac regeneration, which will serve to increase our understanding of how this process could eventually be induced in humans.
Professional discretion in Swedish welfare institutions: What factors influence perceived discretion?
Authors: Schütze Carolin 
Published: October 2022

AbstractDiscretion is a central topic in the literature on service delivery of frontline professionals, especially in the light of neoliberal transformations in all welfare states. Previous studies have focused on exploring “discretionary space” and its meaning for service delivery, but these studies have not been able to clearly identify single determinants of perceived discretion. This study aims to contribute to the discussion by investigating factors that influence perceived discretion. To this end, data were examined from a nationwide survey of Swedish frontline professionals (N = 1319) within two major welfare organizations: the Public Employment Service and the Swedish Social Insurance Agency. Hierarchical OLS regression was applied, resulting in the identification of two major influencing factors. Frontline professionals who reported higher levels of work pressure showed less perceived discretion, and frontline professionals working at the Public Employment Service showed higher levels of perceived discretion than those working at the Social Insurance Agency, highlighting the importance of organizational context for discretion. Greater work experience also proved to increase the feeling of having discretion at work. The results of this paper add to the existing literature by proposing a model of factors that are important for perceived discretion by frontline professionals.

Abstract
Small bowel adenocarcinomas (SBA) are a rare entity associated with a poor prognosis and an advanced stage of disease at diagnosis. Surgical resection is considered the gold standard of treatment for stage I-III, while stage IV disease approach is still debated. We present a case of a young woman affected by a duodenojejunal junction SBA treated with surgical resection and FOLFOX adjuvant chemotherapy. The patient later underwent a palliative duodenojejunal bypass for peritoneal carcinomatosis.

Abstract
Understanding species-specific trait responses under future global change scenarios is of importance for conservation efforts and to make informed decisions within management projects. The combined and single effects of seawater acidification and warmer average temperature were investigated by means of the trait responses of Cymodocea serrulata, a tropical seagrass, under experimental conditions. After a 35 d exposure period, biochemical, morphological, and photo-physiological trait responses were measured. Overall, biochemical traits mildly responded under the individual exposure to high temperature and increasing pCO2 values. The response of C. serrulata was limited to a decrease in %C and an increase in the sucrose content in the rhizome under the high temperature treatment, 32 °C. This suggests that this temperature was lower than the maximum tolerance limit for this species. Increasing pCO2 levels increased %C in the rhizome, and also showed a significant increase in leaf δ13C values. The effects of all treatments were sublethal; however, small changes in their traits could affect the ecosystem services they provide. In particular, changes in tissue carbon concentrations may affect carbon storage capacity, one key ecosystem service. The simultaneous study of different types of trait responses contributes to establish a holistic framework of seagrass ecosystem health under climate change.
Nutrient accumulation and transcriptome patterns during grain development in rice

Published: October 2022

AbstractRice is an important source of calories and mineral nutrients for more than half of the world’s population. The accumulation of essential and toxic mineral elements in rice grain affects its nutritional quality and safety. However, the patterns and processes by which different elements progressively accumulate during grain filling remain largely unknown. In the present study, we investigated temporal changes in dry matter, elemental concentrations, and the transcriptome in the grain of field-grown rice. We also investigated the effects of seed setting rate and the position of the grain within the rice panicle on element accumulation. Three different patterns of accumulation were observed: (i) elements including K, Mn, B, and Ca showed an early accumulation pattern; (ii) dry matter and elements including N, P, S, Mg, Cu, Zn, Mo, As, and Cd showed a mid accumulation pattern; and (iii) elements such as Fe showed a gradual increase pattern. These different accumulation patterns can be explained by the differences in the biogeochemical behavior of the various elements in the soil, as well as differences in plant nutrient redistribution, gene expression, and the sink–source relationship. These results improve our knowledge of the dynamics of elemental accumulation in rice grain and are helpful for identification of functional genes mediating the translocation of elements to grain.
