The effects of presynch-10 and ovsynch on some endometrial tolland nod-like receptor gene expressions in repeat breeder cows [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2019
Subclinical endometritis (SE) is one cause of repeat breeder syndrome (RBS). When endometrial cells come into contact with antigens during inflammatory events like endometritis, they act like innate immune system cells.

Plasma insulin‐like growth‐factor 1 (IGF‐1) concentrations predict early life‐history traits in a wild mammal

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The hormone insulin‐like growth factor 1 (IGF‐1) is a key player in the insulin/IGF signalling (IIS) pathway. Extensive biogerontological research demonstrates that this evolutionarily conserved nutrient‐sensing pathway plays a causal role in the regulation of growth ...

An Economic and Environmental Analysis of Virtual Fencing for Precision Grazing

Journal of Agricultural Economics, EarlyView.
ABSTRACT The UK grazing livestock sector is challenged by declining farm profitability and stringent environmental policy. Innovative technologies such as virtual fencing could enable a balanced economic and environmental performance of beef production. Virtual fencing is a livestock management tool relying on invisible boundaries perceived as auditory,

PATTERN OF INDUCED OESTRUS AND FERTILITY RATE FOLLOWING hCG INJECTION AT EARLY LUTEAL PHASE IN PGF2a TREATED REPEAT BREEDER COWS [PDF]

Journal of Veterinary and Animal Sciences, 2008
A total of 48 repeat breeder cows were divided into three groups viz., group 1, ll and Ill. Cows in group l and 11 were treated with 0.98mg of Tiaprost (PGF2a) on day 70 following natural oestrus (day 0).

Economic benefit in repeat breeder cows using intrauterine infusion of penicillin and estrus synchronization followed by timed artificial insemination

Journal of Advanced Veterinary and Animal Research, 2018
Objective: Until recently, management of repeat breeding in cattle remains a major problem to dairy farmers. This study was carried out to improve the fertility in cows, those did not conceive after three or more consecutive services.

Journal of Dairy Science, 1961
Summary A repeat-breeder is defined as a clinically normal cow which, other factors being optimal, shows a reduced probability of conception. Both fertilization failure and embryonic loss are major causes of repeat-breeding. Much of the embryonic loss occurs between Days 16 and 25 after breeding.

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...
