INVITED REVIEW: Detection and management of pregnancy loss in the cow herd
(2018-12-01)
Various methods and tools have been developed to detect and manage pregnancy loss in cattle to maximize reproductive efficiency by increasing pregnancy rates and decreasing pregnancy loss. Embryonic mortality constitutes ...
Reproductive responses of rabbit does to a supplemental lighting program
(Elsevier B.V., 2005-07-01)
The objective was to investigate whether the productivity of rabbit does can be improved, when natural photoperiod is decreasing, by adopting a supplemental lighting program. Three experiments were conducted involving two ...

Ergatoid reproductives in the Neotropical termite Nasutitermes aquilinus (Holmgren) (Blattaria: Isoptera: Termitidae): developmental origin, fecundity, and genetics
(2019-01-01)
Termite colonies are usually headed by primary reproductives, which establish nests during the swarming season. However, secondary reproductives may develop in some species and become supplementary or replacement breeders, ...
Effect of a Single Intrauterine Dose of Human Recombinant Galectin-1 Buffered on Pregnancy Rate in Inseminated Cows
(2022-03-01)
The objective was to evaluate the efficacy of a single dose of exogenous galectin-1 in improving the pregnancy rate in inseminated cows, comparing the pregnancy rate of the two groups (treatment and control Groups) into ...
Effect of himatanthus sucuuba in maternal reproductive outcome and fetal anomaly frequency in rats
(Wiley-Blackwell, 2015)
The aim of this study was to evaluate the effect of Himatanthus sucuuba on the maternal reproductive outcome and fetal anomaly incidence in rats. Pregnant rats were randomly divided into three experimental groups as follows: ...
Individual and tempo- ral variation in outcrossing rates and pollen flow patterns in Ceiba pentandra (Malvaceae: Bombacoidea)
(2013)
Ceiba pentandra is a tropical tree with high rates of selfing in some populations. In mixed‐mating species, variation in selfing is due to changes in adult density or variability of incompatibility systems. The effect of ...
Side effects of spirotetramat on pupae and adults of a Neotropical strain of Eretmocerus mundus (Hymenoptera: Aphelinidae): Effects on the life parameters and demography
(Springer Heidelberg, 2017-07)
The negative impact of conventional pesticides on the environment is already extensively discussed worldwide. Although the use of chemical agents for controlling agricultural pests remains as first-line strategy for pest ...
Reproduction and Growth in a Neotropical Insectivorous Bat
(2011)
Even though there is an abundance of data regarding the reproductive biology and postnatal growth of bats, comprehensive data on life history is still lacking for most species, particularly for rare families that have ...
