Analysis of Creep Feed Efficiency by a Linear Model on Grazing Japanese Black Cattle Calves

Nihon Chikusan Gakkaiho, 1992
黒毛和種の親子組を用いて,放牧期における子牛へのクリープ飼料の給与の効果について調べた.合計30組の親子組をI群,II群,そしてIII群の3つの区に分割配置し,1990年の4月17日から同年10月24日まで放牧した.I群は開牧前に子牛にクリープ飼料への馴致を行ない,放牧期も引続きクリープ飼料を給与した.II群は馴致は行なわず,放牧期のみクリープ飼料を給与した.III群はクリープ飼料無給与である.クリープ飼料は子牛の採食に合せて追加給与し,体重測定は毎週行なった.解析には,Brodyの成長モデルの誘導関数を含む線形モデルを利用した.子牛の日増体重を目的変数(Y)とし,成長モデルからの誘導関数,飼料摂取量(Cp),馴致の有無(Tr),子牛の性(Sx1,Sx2),母乳の産次(Pt1,Pt2),放牧の歴月 ...

Livestock grazing and geodiversity modulate wild herbivore distributions in an African community conservation area

Wildlife Biology, EarlyView.
The rapid decline of African wildlife populations demands immediate action to mitigate further losses and restore ecosystems. A key factor influencing wildlife distribution is the relationship between the energetic needs of species and the availability of forage, both in terms of quality and quantity.

Evaluation of factors affecting greater prairie‐chicken nest and brood survival

Wildlife Biology, EarlyView.
Greater prairie‐chickens Tympanuchus cupido pinnatus in the Flint Hills ecoregion select recently burned grasslands for brooding and nest in areas that have been unburned for 1–3 years, suggesting the need for a mosaic of burn patches. However, it is unknown how patch area, configuration, and proximity to edges within such mosaics affect reproductive ...

Effects of stocking rate and creep grazing on performance by Spanish and Boer×Spanish does with crossbred Boer kids

Small Ruminant Research, 2007
Abstract Twenty-six Spanish does with twin Boer × Spanish kids and 26 Boer × Spanish does with twin 3/4 Boer–1/4 Spanish kids were used in a 76-day experiment to determine effects of stocking rate (SR) and creep grazing on pre-weaning performance. The study commenced approximately 2 months after kidding. There were four treatments, three involving SR

ACCOUNTING FOR BIODIVERSITY: Periphery Urbanization, Environmental Conflict, and Spatial Inequality in Monetizing the Value of Nature

International Journal of Urban and Regional Research, EarlyView.
Abstract In terms of mainstream sustainability economics, market‐led initiatives aimed at biodiversity restoration represent a productive, morally conscientious choice. Under this view, efforts in areas such as biodiversity offsetting, net gain, or finance are considered effective tools for preventing or managing environmental degradation.

Climatic–Anthropogenic Synergy Drives Escalating Minimum Area Requirements and Connectivity‐Protection Mismatch in a Karst‐Endemic Primate

Integrative Zoology, EarlyView.
Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...

Drivers of Mouse Plagues: Exceptional Rainfall Following Prolonged Drought Triggers Mouse Plagues in Southeastern Australia

Integrative Zoology, EarlyView.
This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...
