Effect of ambient temperature on average daily gain of pigs evaluated using public weather data and a plateau ‐linear regression model
AbstractWe performed a plateau-linear regression model analysis of the average daily gain (ADG) of pigs on daily average temperature at the end of performance testing (T). Records for performance testing between 30 kg and 105 kg of 2268 purebred Duroc pigs raised at the National Livestock Breeding Center Miyazaki Station were used. Off-farm ambient temperatures were measured at the nearest Automated Meteorological Data Acquisition System station at Kobayashi, Miyazaki (Kobayashi station). A plateau-linear regression equation was obtained in which ADG decreased by 12.6 g for every 1°C whenT > 21.1°C. We calc...

Ultra ‐rapid real‐time polymerase chain reaction assay for genotyping of the NT5E gene in Japanese black beef using a mobile PCR device, PCR 1100
AbstractThe concentration of inosine 5 ′-monophosphate (IMP) in beef is an important factor contributing to beef palatability. A previous study suggested that single nucleotide polymorphisms (SNPs) in theecto-5 ′-nucleotidase (NT5E) gene strongly affect the concentration of IMP under postmortem conditions by regulating NT5E enzymatic activity in beef. Genotyping of theNT5E gene is performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) or real-time PCR assay. However, these conventional laboratory assays require large installed instruments. They also involve complicated procedures ...

Intake and apparent digestibility of dry matter, milk production, and composition of cows fed with diets containing oilseed cakes: A meta ‐analysis
The objective was to carry out a meta-analysis and principal component analysis to evaluate the effects of cakes on the intake and apparent digestibility coefficient (ADC) of dry matter (DM) and milk production and composition in lactating dairy cows. The data set used in the meta-analysis came from 51 studies published between 2009 and 2019, which resulted in 119 studies with 18 types of cakes evaluated in 1350 cows. Cows fed with cakes increased dry matter intake (DMI) by 0.366 kg d−1 (P < 0.001) and DMI as a function of the animal's body weight by 0.103% (P < 0.0001) compared with the diet without c...

Dynamic changes of intracellular zinc ion level during maturation, fertilization, activation, and development in mouse oocytes
In this study, we evaluated the amounts and localization of intracellular zinc ions during maturation, fertilization, activation, and embryonic development in mouse oocytes. Our results show that abundant zinc ions are present in both immature and mature oocytes. After in vitro fertilization, the amounts of zinc ions were dramatically decreased at the pronuclear (PN) stage. Ar tificial activation by cycloheximide, SrCl2, and TPEN also reduced the amounts of zinc ions in the PN stage. On the other hand, PN embryos derived from sperm injection still showed high level of zinc ions. However, the amounts of zinc ions rapidly in...
