A review of synchronization of estrus in postpartum cattle.
Odde KG. Odde KG. J Anim Sci. 1990 Mar;68(3):817-30. doi: 10.2527/1990.683817x. J Anim Sci. 1990. PMID: 2180878 Review.
Progestogens administered for 14 to 20 d are effective in synchronizing estrus; however, fertility at the synchronized estrus is subnormal. ...Estrus also has been synchronized effectively by combining a 5- to 9-d progestogen treatment with prostaglandin at o …

Associations between genomic merit for daughter pregnancy rate of Holstein cows and metabolites postpartum and estrus characteristics.
Chebel RC, Veronese A. Chebel RC, et al. J Dairy Sci. 2020 Nov;103(11):10754-10768. doi: 10.3168/jds.2020-18207. Epub 2020 Sep 10. J Dairy Sci. 2020. PMID: 32921462 Free article.
Estrus characteristics recorded from calving to 62 d postpartum were evaluated. ...Selection for GDPR may improve the hormonal and metabolic status of cows postpartum, leading to earlier resumption of cyclicity, and may improve detection of estrus in c …

Estimates of intra- and interclass correlation coefficients for rump touches and the number of steps during estrus in postpartum cows.
Kumro FG, Smith FM, Yallop MJ, Ciernia LA, Mayo LM, Poock SE, Lamberson WR, Lucy MC. Kumro FG, et al. J Dairy Sci. 2021 Feb;104(2):2318-2333. doi: 10.3168/jds.2020-18922. Epub 2020 Nov 25. J Dairy Sci. 2021. PMID: 33246610 Free article.
Estrus traits have economic value in dairy production systems and could be incorporated into genetic selection indices. ...The intraclass correlation (repeatability; estimates of maximum heritability) for rump touches during estrus was 0.22. For study 2, the number …

Postpartum and lactational estrus: a comparative analysis in rodentia.
Gilbert AN. Gilbert AN. J Comp Psychol. 1984 Sep;98(3):232-45. J Comp Psychol. 1984. PMID: 6478785

Estrus detection and estrus detection aids.
Foote RH. Foote RH. J Dairy Sci. 1975 Feb;58(2):248-56. doi: 10.3168/jds.S0022-0302(75)84555-3. J Dairy Sci. 1975. PMID: 1089684 Free article. Review.
Each animal should be identified carefully. The herds man should know all signs of estrus or impending estrus. In addition, for visual detection of estrus to be highly effective, sufficient time must be taken at least twice a day to catch animals with a short …

Regulation of maternal behavior, social isolation responses, and postpartum estrus by steroid hormones and vaginocervical stimulation in sheep.
Soto R, Terrazas A, Poindron P, González-Mariscal G. Soto R, et al. Horm Behav. 2021 Nov;136:105061. doi: 10.1016/j.yhbeh.2021.105061. Epub 2021 Sep 21. Horm Behav. 2021. PMID: 34560419
They isolate themselves from the flock and, contrary to other mammals, do not show postpartum estrus. We investigated the possibility of a common hormonal control of maternal behavior, prepartum social isolation responses, and absence of postpartum estrus …
