仔牛は離乳期は給与飼料の変化や母子分離によるストレスのため、成長が停滞し生産性が低下する。この問題を解決するため、腸内細菌叢を改変し家畜の成長を促すC.hisashiiに着目し検討を行った。その結果、離乳時の発育停滞は起こらず、飼料効率の向上が認められた。また、メタン産生菌であるMethanobrevibacter属の構成割合が減少することを明らかにした。これらのことは、C.hisashiiが腸内細菌叢に影響を及ぼすことで、飼料の利用効率を向上させること、糞からのメタン産生を低下させる可能性があることを示している。

肉牛生産現場では仔牛の減少に伴う仔牛取引価格の高騰が問題になっている。この問題を解決するためには母牛の生涯産仔数を増やすことが必須である。そのためには早期に人工授精(AI:Artificial insemination)が可能な体格を獲得させて初産分娩月齢を早める必要がある。これまでの研究成果より哺乳期の代用乳多給がメス仔牛の発育(特に体高)を向上させることが明らかとなり、代用乳多給によって初産分娩月齢を早期化できる可能性が考えられた。しかし、代用乳多給は標準的なプランが確立されておらず、増体および繁殖成績に及ぼす影響は不明である。
　そこで本研究は、生後3日齢の黒毛和種メス仔牛51頭を3種の異なる代用乳多給プランで飼養管理し、増体および繁殖成績を検討した。試験の結果、AIが可能な体格は体重270kg以上、体高116cm以上であることが明らかとなった。また、試験に供試した51頭のうち7割以上のメス仔牛が代用乳多給により10か月齢時に上記のAIに必要な体格の条件を満たし、51頭の初産分娩月齢平均は22.1か月齢となった。これは令和2年度の全国平均である24.5か月齢より2か月以上短い結果となった。また、３種類の代用乳の多給プランの違いによる初産分娩月齢の比較では、最も早期化できたプランでは21.5か月齢となり、代用乳の多給プランによっては全国平均よりも3か月短くできる可能性も示唆され、新生仔牛にも問題はなかった。一方で、農林水産省が提言している初産分娩月齢の数値目標である23.5か月齢よりも早期化できたことから、新規繁殖技術による畜産業改善ならびに政策形成へも寄与する成果である。

Genetic factors are important for meat quality in cattle and gene expression may be determined by epigenetic control. This may involve Histone Deacetylases (HDACs), which suppress or enhance gene expression, and beta-hydroxybutyric acid (BHBA, produced from butyric acid), which inhibits HDAC activity and increases gene expression. This study aimed to determine how supplementing Japanese Black calves with sodium butyrate in milk replacer affects the relationship between plasma BHBA, HDAC activity in tissues, and blood metabolites. Eight Japanese Black female calves were randomly assigned to two groups of four animals each (control group, and supplementation with sodium butyrate group; NaB). Calves in both groups were fed milk replacer containing 26% Crude Protein (CP), 25.5% Crude Fat (CF), and 116% Total Digestible Nutrients (TDNs), and all calves received calf starter and hay ad libitum. Sodium butyrate was administered to the calves in the NaB group at daily doses of 3 g (from 3 to 30 days of age), 5 g (from 31 to 60 days of age), and 7 g (from 61 to 90 days of age). The supplementation of Japanese Black calves with sodium butyrate in milk replacer decreased plasma concentrations of BHBA.

We have previously found that Epigallocatechin-3-gallate (EGCg), an abundant catechin in green tea, reduced apoptotic signaling and improved muscle recovery in response to reloading after hindlimb suspension (HS). In this study, we investigated if EGCg altered autophagy signaling in skeletal muscle of old rats in response to HS or reloading after HS. Fischer 344 x Brown Norway inbred rats (age 34 months) were given 1 ml/day of purified EGCg (50 mg/kg body weight), or the same sample volume of the vehicle by gavage. One group of animals received HS for 14 days and the second group of rats received 14 days of HS, then the HS was removed and they were allowed to recover by ambulating normally around the cage for two weeks. EGCg decreased a small number of autophagy genes in control muscles, but it increased the expression of other autophagy genes (e.g., ATG16L2, SNCA, TM9SF1, Pink1, PIM-2) and HS did not attenuate these increases. HS increased Beclinl, ATG7 and LC3-II/I protein abundance in hindlimb muscles. Relative to vehicle treatment, EGCg treatment had greater ATG12 protein abundance (35.8%, P < 0.05), but decreased Beclinl protein levels (-101.1%, P < 0.05) after HS. However, in reloaded muscles, EGCg suppressed Beclinl and LC3-II/I protein abundance as compared to vehicle treated muscles. EGCg appeared to "prime" autophagy signaling before and enhance autophagy gene expression and protein levels during unloading in muscles of aged rats, perhaps to improve the clearance of damaged organelles. However, EGCg suppressed autophagy signaling after reloading, potentially to increase the recovery of hindlimb muscles mass and function after loading is restored. (C) 2017 Elsevier Inc.

We aimed to determine the effects of nutritional status on concentrations of somatotropic axis hormones (growth hormone (GH) and insulin-like growth factor 1 (IGF-1)), insulin and metabolites (glucose, total protein and nonesterified fatty acids (NEFA)) in the plasma and colostrum in late antepartum cows. Eight pregnant Japanese Black cows were randomly assigned to two experimental groups (n=4 per group). Control cows (CON) received 100% of their nutritional requirements until parturition, whereas restricted group cows (RES) received 60% of their nutritional requirements. Blood samples were taken during the antepartum period, and blood and colostrum samples were collected on days 0, 1, and 3 after calving. Compared to the CON group, the RES group had higher concentrations of GH and NEFA in plasma, but significantly lower concentrations of glucose and insulin in plasma. The concentrations of GH in plasma after calving were significantly higher, but total plasma protein was significantly lower in RES than in CON cows. Compared to the CON group, the RES group had significantly higher concentrations of GH in colostrum, but significantly lower total concentrations of protein in colostrum. Concentrations of IGF-1 were not different between the two groups. These findings suggest that maternal nutritional status during late gestation influences concentrations of GH and total protein in the blood and colostrum of Japanese Black cows

Alterations in early pre-natal nutrition of Japanese Black calves influence the glucose and lipid metabolism after weaning. However, the effects of early nutritional status on the endocrine system in later life stages in Japanese Black cattle are unknown. This study examined how post-weaning plasma levels of growth hormone (GH), insulin-like growth factor 1 (IGF-1), and blood insulin, which are hormones affecting growth and meat quality, and metabolites were affected by feeding 1800 g versus 500 g of milk replacer to Japanese Black cattle (5 per group) during nursing. Up to weaning (90 days post-birth), all calves received calf starter and hay ad libitum, and post-weaning, they received a concentrate feed and hay ad libitum. Plasma concentrations of GH and IGF-1 were greater at weaning in the high-milk-replacer group (P<0.1 and P<0.01, respectively), and elevated IGF-1 concentrations persisted until the study end (210 d) (P<0.05), suggesting that the levels were sustained independent of the influences of both GH and nutrient intake. Blood insulin and metabolites (plasma glucose, beta hydroxybutyric acid, and non-esterified fatty acids) were not significantly different between the two groups. The results of this study suggest that feeding calves a high volume of milk replacer during nursing will increase IGF-1 secretion well beyond weaning.

This study aimed to determine the effects of feeding an increased volume of high-fat milk during the early post-natal life on metabolite concentrations in the blood, the expression of key genes regulating intermediary metabolism in the skeletal muscles, and the rate of growth of Japanese Black cattle. All calves were fed a high-fat milk replacer (crude protein, 26%; crude fat, 25.5%; total dissolved nitrogen, 116%). Control calves (n = 4) were nursed with 500 g milk replacer until 3 months of age (mo), whereas calves in the experimental group (n = 4) were nursed with 1,800 g milk replacer until 3 mo, and then the volume was gradually reduced until 5 mo. Body weight was significantly higher in the experimental group than in the control group at 7 mo. Plasma glucose concentrations were significantly lower in the experimental group. Expression of glucose-transporter-4 mRNA was lower, whereas that of glucose transporter 1, cluster of differentiation 36, and carnitine palmitoyltransferase-1b mRNA was significantly higher in the M. longissimus thoracis of the experimental group. Nutritional status during early post-natal life appears to strongly influence the growth rate and glucose and lipid metabolism in Japanese Black cattle.

本研究では、腸内細菌叢を最適化し飼料効率を上昇させるBacillus subtilis C-3102 株を給与し、仔牛の暑熱ストレスならびに栄養状態に及ぼすBacillus subtilis C-3102 株の作用を明らかにすることを目的とした。離乳後の黒毛和種雌仔牛（12頭）を供試し（対照区: n = 6, Bacillus subtilis C-3102 株給与区: n = 6）、対照区は市販配合飼料、Bacillus subtilis C-3102株給与区は市販配合飼料に3.0×109 個/ 頭/ 日のBacillus subtilis C-3102 株を添加し給与した。また、乾草は両区ともに自由採食とした。糞中のBacillus subtilis C-3102 株は、給与中に増加した。糞中の総菌数（嫌気）およびBifidobacterium数は、Bacillus subtilis C-3102 株給与中止後に減少した（p<0.05）。日増体量はBacillus subtilis C-3102 株給与前は有意（p<0.01）に小さかったが給与中止後は有意（p<0.05）な増加を示した。暑熱ストレスマーカーである血漿コルチゾール濃度はBacillussubtilis C-3102 株給与区は対照区と比較しBacillus subtilis C-3102 株給与中止後に有意（p<0.01）に減少した。血液代謝産物については、血漿グルコース濃度はBacillus subtilis C-3102 株給与区は対照区と比較しBacillus subtilis C-3102 株給与中止後に増加傾向 （p<0.1）が見られた。血漿コレステロール、NEFA およびTG 濃度は両区の間に有意な差は認められなかった。以上より、Bacillus subtilis C-3102 株は生存したまま下部消化管へ到達し、暑熱下に仔牛の日増体量およびストレスホルモン濃度に影響を及ぼす可能性が示唆された。

ミオスタチンのエネルギー代謝に及ぼす影響を明らかにするため、ミオスタチンを欠損した草原短角牛ならびにミオスタチンが発現している日本短角種牛の骨格筋を用いて、グルコース輸送担体であるGLUT1、GLUT4のmRNA発現、グルコース取り込みに関与するインスリン受容体mRNA発現ならびに脂肪酸輸送担体であるCD36、CPT-1 mRNA発現をリアルタイムPCR法により解析をした。その結果、ミオスタチン欠損した草原短角牛の骨格筋では、インスリン依存型グルコース輸送担体であるGLUT4mRNA発現が上昇していることが明らかとなった。また、脂質代謝については、血中の遊離脂肪酸濃度が草原短角牛で低いことが明らかとなった。
　次に、草原短角牛ならびに日本短角種牛骨格筋筋芽細胞を用いて、筋管への分化誘導後0時、24時ならびに72時間後に同様の遺伝子発現を解析した。その結果、草原短角牛筋芽細胞では、筋分化後72時間においてGLUT4mRNA発現が上昇することが明らかとなり、　一方で、インスリン受容体、GLUT1mRNA発現は両種の間に差はなかった。　以上のことより、ミオスタチンはGLUT4発現を介してグルコース代謝を亢進することが考えられ、さらにその作用はインスリン感受性を上昇させることにより行われる可能性が示唆された。

This study investigated the effect of type-I interferon (IFN) on the expression of matrix metalloproteinases (MMPs) of the bovine endometrial stromal cells (BES) and epithelial cells (BEE). The cells were separated and purified from the caruncles and cultured in DMEM/F-12 containing 10% fetal bovine serum. Spheroids were generated by using ascorbate. Zymograms of the supernatant showed that BEE predominantly expressed MMP-9, whereas MMP-2 was expressed in BES and homo-spheroids. While MMPs expression was not detected in hetero-spheroids. Real-time quantitative PCR revealed that type-I IFN and P4 suppressed the gene expression of MMP-2 and MMP-9 in hetero-spheroids, respectively. On the other hand, gelatin zymography analysis of the supernatant showed that type-I IFN strongly promote the clearance of MMPs. While zymograms of the MMPs stocked in the hetero-spheroids were significantly reduced by type-I IFN. Phenylmethanesulfonyl fluoride and leupeptin (both are serine proteinase inhibitors) significantly repressed the clearance of MMP-2 and MMP-9 induced by type-I IFN. Moreover, collagen fibers in hetero-spheroids significantly decreased after the treatment with type-I IFN. In conclusion, it was suggested that type-I IFN participate in the tissue remodeling by regulation the clearance of MMPs.

This study evaluated the effects of condensed barley distillers soluble (CBDS) on growth rate, rumen fermentation, plasma metabolite, and myofiber properties, and gene expression related to metabolism in the skeletal muscles of Japanese Black calves, compared with soybean meal and corn. Twenty‐four calves were divided into four groups: fed 5% CBDS based on the hay dry matter weight (low CBDS) and fed soybean meal and corn at the same nutrition level (control); and fed 15% CBDS based on the hay dry matter weight (high CBDS) and fed soybean meal and corn at the same nutrition level (high soy). The daily gain was larger in the low (p = 0.08) and high (p < 0.05) CBDS groups compared with the control group. In the CBDS‐fed groups, plasma β‐hydroxybutyric acid concentrations were significantly higher at 6 months of age (p < 0.05), the percentage of type I myofibers was significantly lower and their diameters were significantly larger at 9 months of age (p < 0.05), and carnitine palmitoyltransferase 1b mRNA expression was significantly lower (p < 0.05) and citrate synthase mRNA expression tended to be lower (low; p = 0.06, high; p = 0.05) compared with control group. Thus, feeding CBDS promotes growth and leads to animals with more glycolytic and less oxidative muscle metabolism.

This study evaluated the effects of rice whole crop silage (RWCS) on growth, plasma levels of vitamin A, β‐carotene, vitamin E and IGF‐1, and expression of genes involved in muscle protein degradation and synthesis in Japanese Black calves. Eleven calves were divided into RWCS (fed RWCS ad libitum and concentrate, n = 5) and control groups (fed hay ad libitum and concentrate, n = 6). Final body weight and dairy gain were significantly larger in the RWCS group compared with the control group. Plasma β‐carotene and vitamin E concentrations were significantly higher in the RWCS group compared with control group. Although plasma vitamin E concentration in the RWCS group significantly increased from 4 to 9 months of age, it did not increase in the control group. At 6 months of age in the RWCS group, ubiquitin B (p < 0.05) and calpain 1 (p = 0.097) mRNA expression were lower than control group, but they were not different between groups at 9 months of age. These results indicate that RWCS increases plasma β‐carotene level and promotes muscle growth because of a decrease in the rate of protein degradation, but the effect is lost with the increase in plasma vitamin E level.

【背景・目的】我々は、好熱菌Bacillus hisashii (NITE国際寄託番号BP-863)(IJSEM 65, 2016)の経口給与が肉用仔牛の腸内環境に与える影響について検証し、短期的な投与は病原性大腸菌に起因する下痢症に対する緩解効果が認められた。本研究では、哺乳中と異なりベースとなる腸内フローラが安定化し変動しにくい離乳後をターゲットとして長期的な経口投与による牛の腸内環境と成績に与える影響を解析することを目的とした。
【方法】供試動物として哺乳期黒毛和種仔牛(n=4)を用いて、好熱菌B. hisashii BP-863株経口給与した群、あるいは非給与群に対して2ヶ月間の連続給与とその後1ヶ月の中断期間を設定した。この間における各個体の糞中の代謝物の挙動、細菌叢を解析した上で、飼育成績との関係について検証した。
【結果】糞中の有機酸の濃度について給与前、給与後1ヶ月、2ヶ月、給与中断後1ヶ月で調査した結果、両群の値に顕著な差は認められなかった。一方、菌叢については主に門レベルでFirmicutesとBateroidetesの存在比率が給与後1ヶ月、2ヶ月で有意差が認められ、後者が増えたが、中断後ではその差が少なくなった。この時、日増体重と飼料要求率は、給与群で有意に改善された。以上の結果から、黒毛和種の仔牛の飼育管理におけるBP-863の長期給与の有用性が示唆された。

We investigated the effects of nutrients during nursing period in Japanese Black calves. We used 8 Japanese Black calves. They divided into two groups: one is nursed with replacer milk (crude protein 26 %, crude fat 25.5%, TDN 116% )500g/ day until 3 months of age (mo) and after that fed with concentrate and hay until 10 mo (n=4; the ST group). Another is nursed with replacer milk 1800g until 5 mo and then fed with same feed as group ST until 10 mo (n=4; the EX group). Blood samples were taken from jugular vein at 5, 7 and 10 mo. Concentrations of glucose, insulin, beta-hydroxybutyric acid (βHBA: as one of makers of rumen activity) and nonesterified fatty acid (NEFA) were measured. Body weight was significantly larger in the EX group than in the ST group at 1, 3 to 5, 8 and 10 mo (P< 0.05) and 2, 7 and 9 mo (P< 0.01). Plasma glucose concentrations were significantly larger in the ST group than in the EX group at 7 mo (P< 0.01) and 10 mo (P< 0.05). The plasma concentrations ofβHBA were significantly larger in the ST group than in the EX group at 5, 7 and 10 mo (P< 0.01). There were no significant differences of plasma concentrations of insulin and NEFA between both groups. These results suggested that the nutrients during nursing period would strongly influence the body growth and glucose metabolism in Japanese black cattle. It seems that calves nursed with huge amount of replacer milk might increase growth performance instead of lower rumen activity.
