Effect of intramuscular fat content on the sensory characteristics and dynamic flavor attributes of Japanese black cattle beef
AbstractThe intramuscular fat (IMF) in beef affects its flavor intensity and attributes, which have a significant impact on palatability. We conducted a sensory evaluation by descriptive analysis, Temporal Check-All-That-Apply, and a chemical analysis of 40 ribeye steaks from Japanese Black cattle to determine the relationship among IMF% and sensory characteristics including dynamic flavor attributes. The increased IMF% of Japanese Black cattle beef had intensified sweet and grilled/roasted flavors and reduced off-flavor, whereas excessive IMF% resulted in a decrease in water-soluble precursors of volatile and taste compou...

Changes in piglet and litter characteristics across parities in two highly prolific sow hybrids in an outdoor organic herd
AbstractHigh piglet mortality constitutes a welfare challenge in organic pig production. Litter characteristics were investigated from parities 1 –5 of two hyper-prolific hybrids with different selection traits in an organic commercial herd (DanBred vs. Topigs Norsvin [TN70]). TN70 sows had more functional teats than DanBred sows, and their offspring had higher birth weights. Several interactions between hybrid and parity were found. The to tal born increased with higher parity and was more pronounced for DanBred sows. Litter weight at weaning was higher in parities 1–4 for TN70 compared with DanBred, and within DanBre...

Ethanolamine plasmalogens derived from whale brain stimulate both follicle ‐stimulating hormone and luteinizing hormone secretion by bovine gonadotrophs
AbstractEthanolamine plasmalogens (EPls) are the only known ligands of a novel receptor, G protein-coupled receptor 61, and bovine brain EPls stimulate follicle-stimulating hormone (FSH) but not luteinizing hormone (LH), secreted by bovine gonadotrophs. We hypothesized that the brain EPls of whales (Balaenoptera edeni), anotherCetartiodactyla with at least twice the lifespan of bovines, could stimulate FSH secretion by gonadotrophs. To test this hypothesis, bovine gonadotrophs (from approximately 2-year-old Japanese Black heifers) were cultured for 3.5 days and treated with increasing concentrations of brain EP1s from wh...

Physicochemical properties and structural changes of chicken breast meat subjected to radio frequency tempering combined with conventional thawing treatments
AbstractBeing able to thaw frozen meat in a reasonable time without impairing quality is crucial for industry and households. Radio frequency (RF) techniques have been used to defrost frozen foods. The influences of RF (50 kW, 27.12 MHz) tempering combined with water immersion (WI, 20°C) thawing (RFWI) or air convection (AC, 20°C) thawing (RFAC) on the physicochemical and structural changes of chicken breast meat were investigated, and the results were compared with those of the fresh meat (FM) and the meat sam ples subjected to WI and AC only. The thawing processes were terminated when the core temperatures of the ...

Precalving behavior in dairy cattle with different calving times
In this study, we analyzed the behavior of pregnant dairy cattle for 7 days prior to calving, to assess the feasibility of predicting the calving time. Eleven Holstein cows were divided into two groups based on their calving times, that is, in the morning (the Morning Parturition Group) or the evening (the Evening Parturition Group). Their behavior was recorded on v ideo. An analysis was conducted of the daily occurrences of each type of behavior and the number of switches of behavior during the day and at night. A statistical analysis was conducted, using a two-way factorial analysis. The behavioral sequence was analyz...

Genome ‐wide detection of changes in allelic frequency in Landrace pigs selected for resistance to mycoplasma pneumonia of swine
AbstractClosed-pig line breeding could change the genetic structure at a genome-wide scale because of the selection in a pig breeding population. We investigated the changes in population structure among generations at a genome-wide scale and the selected loci across the genome by comparing the observed and expected allele frequency changes in mycoplasma pneumonia of swine (MPS)-selected pigs. Eight hundred and seventy-four Landrace pigs, selected for MPS resistance without reducing average daily gain over five generations, had 37,299 single nucleotide polymorphisms (SNPs) and were used for genomic analyses. Regarding popu...

Use of a commercial indoor positioning system for monitoring resting time and moving distance in group ‐housed dairy calves
AbstractTo assess the usefulness of a commercially available indoor positioning system for monitoring the resting time and moving distance in group-housed dairy calves as indicators of their health status, five dairy calves were housed in a free barn, and their coordinate was recorded. The mean displacement (cm/s) within a minute showed a double-mixture distribution. Actual observations revealed that the minutes in the first distribution with shorter displacement were mostly the time that the calves spent lying. To predict the daily lying time and moving distance, a mixed distribution was divided at a threshold value. The ...

Rumen microbial composition associated with the non ‐glucogenic to glucogenic short‐chain fatty acids ratio in Holstein cows
This study aimed to determine the physiological features and rumen microbial composition associated with the non-glucogenic-to-glucogenic short-chain fatty acids ratio (NGR). Holstein cows were housed in a free-stall barn with an automatic milking system and fed a partially mixed ration. Physiological and microbial analyses were performed on 66 datasets collected from 66 cows (50 –250 days in milk). NGR was positively correlated with ruminal pH, relative abundances of protozoa and fungi, methane conversion factor, methane intensity, plasma lipids, parity, and milk fat, and negatively correlated with total short-chain f...

Prediction of methane emissions from fattening cattle using the methane ‐to‐carbon dioxide ratio
This study aimed to develop a prediction equation for methane (CH4) emissions from fattening cattle based on the CH4/carbon dioxide (CO2) ratio and validate the predictive ability of the developed equation. The prediction equation was developed using the CH4/CO2 ratio combined with oxygen consumption and respiratory quotient estimations that were theoretically calculated from the relation between gas emissions and energy metabolism. To validate the prediction equation, gas measurements in the headboxes were conducted using eight Japanese Black steers. The predictive ability of the developed equation was compared with that ...
