Interpretive Summary: Whole genome sequence analyses-based assessment of virulence potential and antimicrobial susceptibilities and resistance of Enterococcus faecium strains isolated from commercial swine and cattle probiotic products
Probiotics, also called direct-fed microbials, are widely used in swine and cattle production systems, as an alternative for antibiotics. The benefits of feeding probiotic products include growth promotion and gut functional benefits.

Interpretive Summary: Effects of harvest date and growth stage on triticale forages in the southwest United States: agronomic characteristics, nutritive value, energy density, and in vitro disappearance of dry matter and fiber
Our objectives were to screen 14 triticale cultivars for agronomic and nutritive value characteristics with specific emphasis on identifying typical, as well as deviant, responses to the calendar date and plant maturity.

Interpretive Summary: Effects of harvest date and growth stage on triticale forages in the southwest USA: kinetics of in vitro disappearance of fiber and dry matter
Unless there is an urgency for removing the triticale crop, such as those created by a feed shortage or need to establish a secondary crop, harvest management decisions should be based on plant growth stage, and not calendar date.

Interpretive Summary: Novel Synthetic oviductal fluid for Conventional Freezing 1 (SCF1) culture medium improves development and cryotolerance of in vitro produced Holstein embryos
In vitro produced (IVP) bovine embryos suffer from several physiological abnormalities that interfere with their ability to withstand the freezing process, a vital step in shipping and distribution of IVP embryos.

Interpretive Summary: Intake, ruminal fermentation parameters, and apparent total-tract digestibility by beef steers consuming Pensacola bahia grass hay treated with calcium oxide
With the ever-growing desire to increase efficiency in beef cattle production, researchers have developed strategies such as treating poor-quality forages with chemicals to increase the digestibility of fiber fractions, consequently increasing their energy value for cattle feeding.

Interpretive Summary: Identify known and novel candidate genes associated with backfat thickness in Duroc pigs by large-scale genome-wide association analysis
Backfat thickness (BFT) is a complex and economically important trait in the pig industry because it reflects fat deposition and can be used to measure the carcass lean meat percentage in pigs.

Interpretive Summary: Effects of a novel consensus bacterial 6-phytase variant on the apparent ileal digestibility of amino acids, total tract phosphorus retention, and tibia ash in young broilers
Microbial phytase is widely used in commercial broiler diets to improve digestion of phosphorus (P) and reduce its excretion into the environment. Phytase improves the digestion of phosphorus and other nutrients including amino acids (AA).

Interpretive Summary: Transcriptome analyses indicate that heat stress-induced inflammation in white adipose tissue and oxidative stress in skeletal muscle is partially moderated by zilpaterol supplementation in beef cattle
Heat stress (HS) negatively impacts livestock health and carcass quality. Supplementation of livestock with β-adrenergic agonists (β-AA) increases muscle mass and decreases fat.

Interpretive Summary: Correlations of gestational hemoglobin level, placental trace elements content, and reproductive performances in pregnant sows
Iron deficiency and iron excess may cause adverse outcomes during pregnancy. In sows’ feed, iron is added as ferrous sulfate, ferrous glycine, or other forms to improve their reproductive performance and prevent iron-deficiency anemia in their offspring.

Interpretive Summary: Genetic parameters, heterosis, and breed effects for body condition score and mature cow weight in beef cattle
The current study estimated the genetic relationship between mature cow weight (MWT) and body condition score (BCS), heterosis, and breed effects for these traits in a crossbred beef population. In total, 25,035 and 24,522 overlapping records were available for MWT and BCS, respectively. Pedigree was available for 48,013 individuals.

Science Advisor Resigns After Violating Workplace-Behavior Rules
“The investigation found credible evidence of instances of multiple women having complained to other staff about negative interactions with Dr. Lander, where he spoke to them in a demeaning or abrasive way in front of other staff,” Christian Peele, the White House’s deputy director of management and administration for personnel, said in a recording obtained by Politico.
