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...

Modification of dietary rumen degradable starch content by chemical processing of feed ingredients: A meta ‐analysis
This study aimed to evaluate the chemical processing of ruminant feed ingredients on rumen degradable starch (RDS) and starch degradation kinetics in the rumen. A database was constructed from a total of 34 articles, consisted of 100 observations. The articles were searched and identified from the Scopus platform. Data were analyzed by using the fixed effect model. The types of chemical processing in this study included sodium hydroxide, ammonia, potassium aluminum, urea, formaldehyde, and organic acid. Results indicated that chemical processing significantly reduced the RDS content (p <  0.001) and the immediately ...

Egg ‐laying capacity of parent flock geese at different stocking densities
This article presents the results of studies aimed at establishing the optimal stocking density of purebred and hybrid geese of the parent flock, taking into account the indicators of their live weight and egg production. When conducting research, the stocking density of geese was established depending on the breed and shape. Different stocking densities of geese in groups were achieved due to their different numbers in groups: Kuban 1.2; 1.5; 1.8 birds/m2, large gray 0.9; 1.2; 1.5 birds/m2, hybrid bird 1.0; 1.3; 1.5 birds/m2. It was revealed on the basis of the analysis of the productive qualities of adult geese that the ...

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 ...
