Special Issue Information

Dear Colleagues,

I am delighted to announce a Special Issue of Animals on “Therapeutics of Twin Pregnancies in Dairy Cattle”, due to the increase new strategies that recently appear to reduce them. This Special Issue is focused on new techniques to identify and diminish the great negative economic impact of twin pregnancies and twin parturition in cattle. It is also aimed at increasing knowledge of therapeutics than can be applied in commercial dairy herds for experts in the weekly reproductive visits. 

Year by year, twin pregnancies and multiple ovulations are dramatically increasing in high-producing dairy herds. Sometimes this is attributed solely to high milk production, but little by little, the scientific community is realizing that, as with many reproductive events, this is a multifactorial problem. Regardless, well-managed high-producing dairy herds need solutions to the increasing pressure to reduce the use of antibiotics and increase the lifespan of dairy cattle. Twin pregnancies are one of the problems with the greatest negative impacts on both factors. Scientists, veterinarians, and clinicians should work together to mitigate the strong economic pressure placed upon herds by administrations.

It is vital for the future of dairy farms that research is focused on determining factors that increase double ovulations, properly learning how to recognize a twin pregnancy, and establishing a proper action protocol as in mare or human pregnancies. Dairy cattle veterinarians should improve at pace with farms. For that reason, this Issue tries to shed some light on therapeutics of twin pregnancies.

Twin Pregnancies in Dairy Cattle: Observations in a Large Herd of Holstein-Friesian Dairy Cows

Multiple pregnancies have devastating consequences on the herd economy of dairy cattle. This observational study examines incidence patterns based on data from the ultrasonographic examination of 1130 multiple pregnancies in cows in their third lactation or more carrying twins (98.8%), triplets (1.1%), or quadruplets (0.08%), and 3160 of their peers carrying singletons. Cows became pregnant following a spontaneous estrus with no previous hormone treatments. Irrespective of a significant decrease (p < 0.0001) in the conception rate (28–34 days post-insemination) during the warm period of the year, the multiple pregnancy rate was similar for both warm (26.5%) and cool (26.3%) periods. The incidence of unilateral multiple pregnancies (all embryos in the same uterine horn) was higher than that of bilateral pregnancies (at least one embryo in each uterine horn): 54.4% versus 45.6% (p < 0.0001). This difference rose to 17% during the warm season (p = 0.03). Pregnancy was monitored in unilateral multiple pregnancies until abortion or parturition (n = 615). In the warm period, the parturition rate was 43% compared to 61% recorded in the cool period (p < 0.0001). Thus, a warm climate is the main factor compromising the fate of multiple pregnancies. Some clinical suggestions are provided. Full article

Multiple ovulations and so multiple pregnancies have increased recently in dairy cattle. The incidence of the double ovulation impact in high producers at insemination may be over 20%. Twin pregnancies are undesirable as they seriously compromise the welfare and productive lifespan of the cow and herd economy. Clinical problems extend from the time of pregnancy diagnosis to pregnancy loss, abortion or parturition. Early pregnancy loss or abortion of multiple pregnancies lead in most cases to culling. In cows reaching their term, mean productive lifespan is up to about 300 days shorter for cows delivering twins than for cows delivering singletons. While there is an urgent need to address multiple pregnancy prevention procedures in the foreseeable future, the incidence of twin pregnancies continues to rise in parallel with increased milk production. Herein, we review two contrasting measures proposed for the time of twin pregnancy diagnosis: (1) gonadotropin-releasing hormone treatment for pregnancy maintenance, or (2) embryo reduction. These options are discussed in terms of their implications for individual animal health and herd economy. Our main conclusions find that manual twin reduction has proven to be the best management option, whereas the use of prostaglandin F for inducing abortion may be a better option than doing nothing.
