Income Upgrading Model of Cattlemen in the Utilization of Artificial Insemination Technology: a Case Study in Village of Kanonang III, Regency of Minahasa [PDF]

open access: yes, 2013
Cattlemen allocate labor on their cattle business. These activities have contributed further to the family income used to meet household needs. Besides the beef business, they seek food crops such as rice, corn, peanuts and so forth to obtain additional ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Evaluation of bovine leukaemia virus infection control measures in Japanese Black beef cattle breeding farms: A 7‐year longitudinal study based on proviral load

open access: yesVeterinary Record Open, Volume 13, Issue 1, June 2026.
Abstract Background Bovine leukaemia virus (BLV) infection remains a major problem for Japanese Black (Wagyu) cattle, and effective and sustainable control measures are essential to prevent its spread in breeding herds. This study aimed to monitor the BLV infection status of all cattle at a Japanese Black breeding farm in Kagoshima Prefecture, Japan ...

Assessing the Value of Coordinated Sire Genetics in a Synchronized AI Program [PDF]

open access: yes
Synchronized artificial insemination was used to inseminate cows using different types of sire genetics, including low-accuracy, calving-ease, and high-accuracy. These three calf sire groups were compared to calves born to cows bred using natural service.

Different estrous induction methods during the non-breeding season in Kivircik ewes

open access: yesVeterinární Medicína, 2006
The efficiency of medroxyprogesterone acetate (MAP) sponges in combination with either pregnant mare serum gonadotrophin (PMSG) or cloprostenol (PGF2α) for inducing and synchronizing the estrous cycle in non-lactating Kivircik ewes was investigated ...

Solitary Confinement: Surprising Post‐Copulatory Behaviour of an Australian Species of Wishbone Spider (Mygalomorphae: Anamidae: Aname)

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Araneomorph spiders are regarded as a model group for sexual selection studies, while the mating system of mygalomorph spiders remains largely unknown. We here report on the mating behaviour of an Australian wishbone spider species, involving a novel post‐copulatory behaviour for mygalomorph spiders (‘burrow plugging’).

Migration rate, timing of sex, and resident genetic diversity jointly shape effective gene flow during rotifer colonization

open access: yesLimnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Dispersal is a complex process that affects all living organisms, with the settlement phase being particularly critical. This phase depends on the interaction between the environmental conditions of the new habitat and the biological traits of both resident and immigrant populations.
