The demand for beef as a protein source is increasing worldwide, although in most countries accounts considerably less than half of total meat consumption. Beef also provides highly desirable eating experience developed and, increasingly, developing countries. sustainability production has different meanings the various geographical and socio-economic regions world. Natural resources including land mass uses, rainfall access to livestock feed, robustness economy are major determinants...
Regulation of Wnt signaling is essential for embryonic patterning. Sfrps are secreted antagonists that directly interact with the ligand to inhibit signaling. Here, we show Sfrp1 and Sfrp2 required anteroposterior (AP) axis elongation somitogenesis in thoracic region during mouse embryogenesis. Double homozygous mutations lead severe shortening region. By contrast, a mutation one or other exerts no effect on embryogenesis, indicating functionally redundant. The defect shortened appears be...
In Japan, Wagyu cattle include four types of Japanese cattle: the Black, Brown, Shorthorn, and Polled breeds. The famous brand name includes not only Black produced in but also animals or even crossbred foreign countries such as Australia USA.
This review addresses the characteristics and health benefit of highly marbled Wagyu Hanwoo beef. Marbling beef has been increased in Japan Korea to meet domestic consumer preferences. cattle have high potential accumulating intramuscular fat (IMF) producing The IMF content varies depending on feeding time, finishing diet, breed type. increases when time is increased. rate increase grain-fed faster than that pasture-fed cattle. Fatty acid composition are also different breeds. Highly higher...
Objectives: This study investigated the long-term effects of maternal undernutrition on overall muscle metabolism, growth performance, and characteristics in postnatal offspring Wagyu (Japanese Black) cattle. Methods: cows were divided into nutrient-adequate (control, CNT; n=4, 120% requirements) nutrient-restricted groups (NR; n=4; 60% requirements), treated from day 35 gestation until parturition. Diets delivered basis crude protein requirements, meeting 100% 80% dry matter requirements...

To elucidate the mechanisms underlying maternal undernutrition (MUN)-induced fetal skeletal muscle growth impairment in cattle, longissimus thoracis of Japanese Black calves at 8.5 months utero was analyzed by an integrative approach with metabolomics and transcriptomics. The pregnant cows were fed on 60% (low-nutrition, LN) or 120% (high-nutrition, HN) their overall nutritional requirement during gestation. MUN markedly decreased bodyweight weight fetus. levels amino acids (AAs)...
Abstract This study aimed to investigate the effects of high and low levels energy intake during entire gestation period on skeletal muscle development, organ adipose tissue accumulation in fetuses Wagyu (Japanese Black) cows, a breed with highly marbled beef. Cows were allocated high‐nutrition ( n = 6) group (fed 120% nutritional requirement) or low‐nutrition 60% requirement). The cows artificially inseminated semen from same sire, removed by cesarean section at 260 ± 8.3 days fetal age...
Tektins (TEKTs) are constitutive filamentous proteins of microtubules in cilia, flagella, basal bodies, and centrioles. In mammals, five TEKTs (TEKT1, 2, 3, 4, 5) have been identified testis spermatozoa. With the exception TEKT1, these reported to be present spermatozoa with predominant localization at peri-axoneme structures i.e., mitochondria outer dense fibers. study, we produced an antibody against TEKT1 examine mouse, bull, rat By immunoblot analyses immunofluorescence microscopy, found...
The amount and distribution of intramuscular fat in beef pork are some the most important quality characteristics because they highly influence nutritional value eating meat.Magnetic resonance imaging (MRI) is a suitable non-invasive alternative method that can provide both qualitative quantitative information on meats with high spatial information.In this study, we used MRI technique combination image processing tools for visualization prediction meats.The results from analysis were...
Abstract Free amino acids are important components of tastants and flavor precursors in meat. To clarify the correlation between muscle fiber type free acids, we determined concentrations various dipeptides samples different tissues ( n = 21), collected from 26‐month‐old Japanese Black steers 3) at 2 days postmortem. The proportions myosin heavy chain (My HC ), slow 1) fast 2) isoforms were by sodium dodecyl sulfate–polyacrylamide gel electrophoresis SDS – PAGE ). contents measured high...
The purpose of this study was to develop a detection technique for adulterated powder products using Raman spectroscopy.While conventional methods food quality analysis require time and pretreatment procedures, spectroscopy can be used detect component rapidly nondestructively without pretreatment.In study, spectra were measured 785 nm laser source in the range 3,200~170 cm -1 multivariate analytical method partial least square regression (PLSR) applied optimal models predicting mixed...
This study aimed to elucidate the effects of maternal undernutrition (MUN) on epigenetic modification hepatic genes in Japanese Black fetal calves during gestation. Using a previously established experimental design feeding dams with 60% (LN) or 120% (HN) their global nutritional requirements 8.5-month gestational period, DNA methylation liver was analyzed reduced representation bisulfite sequencing (RRBS). The promoters and gene bodies LN fetuses were hypomethylated compared HN fetuses....
ABSTRACT The compositional characteristics of the three basic types myofiber, namely type I (slow‐twitch oxidative), IIA (fast‐twitch oxidative glycolytic) and IIB glycolytic), are clarified in skeletal muscles Japanese Black cattle. myofiber composition, which is characteristic cattle, markedly changes during their growth, when some myofibers transformed into or IIB, depending on different muscles. Independent these with inter‐ intramuscular variations distribution evident. small extensor...
1. Using adult Silkie and White Leghorn (WL) chickens, fibre composition total collagen content were compared between M. iliotibialis lateralis (ITL) pectoralis (PT). 2. Fibres divided into type IIR IIW showing strong weak reduced nicotinamide adenine dinucleotide dehydrogenase activities, respectively. 3. Fibre differed markedly ITL PT muscle. muscle was composed of both types but only IIW. Breed difference on noted in cocks (type IIR; 53.8% WL 37.0%). 4. Total greater muscles muscles....
