“…Significant imprinting variances and largest PRIVs and RIVs of carcass traits in our study were found for BMS (Tables 2–4) in Models 1 and 2. These parental contributions for BMS were caused by maternal gametic effects, i.e., they were paternally imprinted as described by Okamoto et al (2019) that showed largest RIV for BMS (35.17%) of the carcass traits, and a larger maternal (75.15%) than paternal contribution (24.85%) to the imprinting variance in Japanese Black cattle. For fat‐related traits, the variance ratio for maternal gametic effects on BMS in the present study was larger than that reported in previous studies using European beef breeds.…”

“…Expected variances that are the same as those from Model 1 can be derived from the variance components of the sire–MGS model, and the equations given by Okamoto et al. (2019) are as follows:

σ_{normalA}^{2} = 2 σ_{sire}^{2} + 8 σ_{mgs}^{2}

σ_{normali}^{2} = 2 σ_{sire}^{2} + 8 σ_{mgs}^{2} ‐ 8 σ_{sire, mgs}

σ_{normalM}^{2} = 8 σ_{sire,mgs}

σ_{gs}^{2} = 2 σ_{sire}^{2} ‐ 4 σ_{sire,mgs}

σ_{gd}^{2} = 8 σ_{mgs}^{2} ‐ 4 σ_{sire, mgs}

“…The data and samples were collected from different Japanese Black population in the previous study (Shimane prefecture) by Okamoto et al. (2019). Historically, most of the breeding projects for Japanese Black cattle have been carried out within prefectures, and the breed is genetically subdivided into several local subpopulations (Honda, Nomura, Yamaguchi, & Mukai, 2004).…”

Genomic imprinting should be considered in animal breeding systems to avoid lead in bias in genetic parameter estimation. The objective of this study was to clarify the effects of pedigree information on imprinting variances for carcass traits and fatty acid composition in Japanese Black cattle. Carcass records [carcass weight, rib eye area, rib thickness (RT), subcutaneous fat thickness and beef marbling score (BMS)] and fatty acid composition were obtained for 11,855 Japanese Black feedlot cattle. To estimate and compare the imprinting variances for the traits, two imprinting models with different pedigree information [the sire–dam gametic relationship matrix (Model 1) and the sire–maternal grandsire (MGS) numerator relationship matrix (Model 2)] were fitted. The ratio of the imprinting variance to the total additive genetic variance for RT (6.33%) and BMS (19.00%) was significant in Model 1, but only that for BMS (21.09%) was significant in Model 2. This study revealed that fitting the sire–MGS model could be useful in estimating imprinting variance under certain conditions, such as when restricted pedigree information is available. Furthermore, the present result suggested that the maternal gametic effects on BMS should be included in breeding programmes for Japanese Black cattle to avoid selection bias caused by imprinting effects.

Epigenetic changes induced in the early developmental stages by the surrounding environment can have not only short-term but also long-term consequences throughout life. This concept constitutes the “Developmental Origins of Health and Disease” (DOHaD) hypothesis and encompasses the possibility of controlling livestock health and diseases by epigenetic regulation during early development. As a preliminary step for examining changes of epigenetic modifications in early embryos and their long-lasting effects in fully differentiated somatic tissues, we aimed to obtain high-throughput genome-wide histone H3 lysine 4 trimethylation (H3K4me3) profiles of bovine blastocysts and to compare these data with those from adult somatic tissues in order to extract common and typical features between these tissues in terms of H3K4me3 modifications. Bovine blastocysts were produced in vitro and subjected to chromatin immunoprecipitation-sequencing analysis of H3K4me3. Comparative analysis of the blastocyst-derived H3K4me3 profile with publicly available data from adult liver and muscle tissues revealed that the blastocyst profile could be used as a “sieve” to extract somatic tissue-specific modifications in genes closely related to tissue-specific functions. Furthermore, principal component analysis of the level of common modifications between blastocysts and somatic tissues in meat production-related and imprinted genes well characterized inter- and intra-tissue differences. The results of this study produced a referential genome-wide H3K4me3 profile of bovine blastocysts within the limits of their in vitro source and revealed its common and typical features in relation to the profiles of adult tissues.
