Serum Vitamin C Concentration in Fattening and Fattened Beef Cattle
Nihon Chikusan Gakkaiho, 1999 反芻家畜は充分量のビタミンCを体内で合成することができるとされているが,子牛や乳牛においてビタミンC欠乏が報告されている.一方,肥育牛におけるビタミンC栄養状態はほとんど検討されていない.そこで,本試験では肥育牛の屠畜時におけるビタミンC栄養状態を血清中ビタミンC濃度の指標として調査するとともに,肥育過程における血清中ビタミンC濃度変化を検討した.市場に出荷された黒毛和種牛の屠畜時における血清中ビタミンC濃度は,26.4±22μM(4.6～95.3μM)であった.このように黒毛和種牛の屠畜時における血清中ビタミンC濃度は個体間の変動が大きく,一部のウシではビタミンCが欠乏している可能性が示唆された.ついで,黒毛和種牛の肥育に伴う血清中ビタミンC濃度の変化を測定した ...

Variants of fattening and flavor symmetry restoration
, 1999 We study the effects of different "fat link" actions for Kogut-Susskind quarks on flavor symmetry breaking. Our method is mostly empirical - we compute the pion spectrum with different valence quark actions on common sets of sample lattices.

Methane emissions from fresh dairy cattle and pig slurry
Journal of Environmental Quality, Volume 55, Issue 3, May/June 2026.Abstract During manure storage, methane (CH4) is produced by anaerobic decomposition of organic matter by methanogens. Frequent removal and further processing of manure from the barn can reduce CH4 emissions. However, little is known about how much CH4 is lost during the adaptation of methanogens to the changing environment from the gut to storage. The

Population dynamics of Townsend's big‐eared bats: effect of age and drought on survival
The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.We estimated age‐specific yearly survival of female Townsend's big‐eared bats in Inyo and Mono Counties, California. We found that both juvenile and adult survival were negatively impacted by drought, and that detection probability was lower for hand‐recapture than for bats detected via pass‐through antenna arrays.
