Borsanyi S, Fodor Z, Guenther J, Kara R, Katz S, Parotto P, et al.
Phys Rev Lett . 2021 Jun; 126(23):232001. PMID: 34170171
In this Letter, we introduce a novel scheme for extrapolating the equation of state of QCD to finite chemical potential that features considerably improved convergence properties and allows us to...

Borsanyi S, Fodor Z, Guenther J, Hoelbling C, Katz S, Lellouch L, et al.
Nature . 2021 Apr; 593(7857):51-55. PMID: 33828303
The standard model of particle physics describes the vast majority of experiments and observations involving elementary particles. Any deviation from its predictions would be a sign of new, fundamental physics....

Carvalho P, Guenther J, Fuenzalida M, Amundson M, Wiltbank M, Fricke P
J Dairy Sci . 2014 Aug; 97(10):6305-15. PMID: 25087033
Presynchronization strategies, such as Presynch-Ovsynch and Double-Ovsynch, increase fertility to timed artificial insemination (TAI) compared with Ovsynch alone; however, simpler presynchronization strategies could reduce costs and simplify reproductive management. Lactating...

Carvalho P, Souza A, Amundson M, Hackbart K, Fuenzalida M, Herlihy M, et al.
J Dairy Sci . 2014 Apr; 97(6):3666-83. PMID: 24731646
The relationship between energy status and fertility in dairy cattle was retrospectively analyzed by comparing fertility with body condition score (BCS) near artificial insemination (AI; experiment 1), early postpartum changes...

Ferraretto L, Gencoglu H, Hackbart K, Nascimento A, Dalla Costa F, Bender R, et al.
J Dairy Sci . 2013 Dec; 97(2):754-63. PMID: 24359832
The objective of this trial was to evaluate the effects of feed restriction (FR) on serum glucose, nonesterified fatty acids, progesterone (P4), insulin, and milk production in dairy cows. Eight...

Bender R, Hackbart K, Dresch A, Carvalho P, Vieira L, Crump P, et al.
J Dairy Sci . 2013 Dec; 97(2):764-78. PMID: 24359829
Multiple metabolic and hormonal factors can affect the success of protocols for ovarian superstimulation. In this study, the effect of acute feed restriction and increased LH content in the superstimulatory...

Carvalho P, Souza A, Sartori R, Hackbart K, Dresch A, Vieira L, et al.
Theriogenology . 2013 Oct; 80(9):1074-81. PMID: 24084230
The primary objective of this study was to determine the effect of site of semen deposition on fertilization rate and embryo quality in superovulated cows. The hypothesis was that deposition...

Lopes Jr G, Giordano J, Valenza A, Herlihy M, Guenther J, Wiltbank M, et al.
J Dairy Sci . 2013 Apr; 96(6):3788-98. PMID: 23587390
Lactating Holstein cows (n=1,456) were randomized in a 2×2 factorial design to compare the main effects of day of initiation of resynchronization after artificial insemination (AI; 32 vs. 39 d)...

Nascimento A, Bender R, Souza A, Ayres H, Araujo R, Guenther J, et al.
J Dairy Sci . 2013 Mar; 96(5):2873-82. PMID: 23453519
Reproductive management programs that synchronize ovulation can ovulate a smaller than normal follicle, potentially resulting in inadequate progesterone (P4) concentrations after artificial insemination (AI). Ovulation of the dominant follicle of...

Nascimento A, Souza A, Guenther J, Costa F, Sartori R, Wiltbank M
Reprod Fertil Dev . 2012 Oct; 25(5):818-24. PMID: 23058209
Adequate circulating progesterone (P4) is important for pregnancy. Lactating dairy cattle have lower circulating P4, particularly when smaller follicles are ovulated during timed AI protocols. The aim of the present...
