乳房カバーを用いた短時間の授乳制限が耕作放棄地放牧における母子ヤギの行動と搾乳量に及ぼす影響

本研究では，耕作放棄地放牧飼育における粗放的搾乳方式を検討するために，自然哺乳時の授乳行動に基づき，母ヤギに乳房カバーを装着して短時間授乳を制限した場合の母子の行動と搾乳量を検討した．放牧されている6組のザーネン種ヤギ母子を，出産後0.8〜6.2ヵ月時に計18回，自然授乳させる平常日と，乳房カバーを用いて2〜6時間授乳を制限する装着日を設けて，昼間11時間連続の行動観察を実施するとともに，装着日には観察後に搾乳量を測定した．母子の空間的分離を伴わない乳房カバーを用いた授乳制限は，母子双方の唾液中コルチゾル濃度に影響せず，母ヤギの行動や食草時の空間分布にも悪影響することなく，試験期間を通して210〜360mL/頭と安定した搾乳量を得ることを可能にした．以上から，耕作放棄地で放牧飼育されている母ヤギに乳房カバーを装着しての搾乳方式は，母子ヤギに悪影響を及ぼすことなく搾乳が可能な方式であると結論した．

Adiponectin,leptin: focus on low-protein diet supplemented with keto acids in chronic glomerulonephritis with hbv patients

Leptin and adiponectin come from adipose tissue, which can reflect patients' inflammation and status of lipid metabolism. Our study is aim to evaluate the effects of short-term restriction of dietary protein intake (DPI) supplemented with keto acids on nutrition and lipid metabolic disturbance in chronic glomeruloneph-ritis with HBV patients. 17 patients were randomized to either low DPI with keto acid-supplemented (sLP) or low DPI (LP) group for 12 weeks. Low-protein diet (LPD) wasindividualized with protein intake of 0.6–0.8 g/kg/day and keto acids were supplied in 0.1 g/kg/day. Nutritional index other clinical index were measured to evaluate the effect and safey respectively. Serum levels of adiponectin, leptin were determined by ELISA assay.The urine protein excretion level was significantly decreased after 12 weeks in the sLP group compared to the basal value and the LP group (baseline:4.52±1.74,4 weeks:3.19±1.52 g,8 weeks: 2.19±1.1 g,12 weeks:1.64±0.77 g, P In conclusion: Short-term restriction of DPI 0.6–0.8 g of protein/ kg IBW/day is safe, when combined with keto acids, is associated with decreased of urinary protein and improvement of lipid metabolism
