Forage and splanchnic tissue mass in growing lambs: Effects of dietary forage levels and source on splanchnic tissue mass in growing lambs [PDF]

British Journal of Nutrition, 1994
Forty-two crossbred lambs (33·4 kg initial body weight; twenty-four wethers and eighteen ewes) were used in a 42 d experiment with a 2 × 3 factorial treatment arrangement to determine effects of forage level and source on splanchnic tissue mass. Diets were 250 and 750 g/kg of chopped lucerne (Medicago sativa) (A), ryegrass (Lolium multiflorum)–wheat ...

<b>Forage mass and nutritive value of bermuda grass mixed to forage peanut or common vetch [PDF]

Acta Scientiarum. Animal Sciences, 2016
Three pasture-based systems (PS) with  bermuda grass (BG) + forage peanut + 75 kg of N ha-1; BG + common vetch + 75 kg of N ha-1 and BG + 150 kg of N ha-1 were evaluated. Lactating Holstein cows were used for evaluation and the experimental design was completely randomized.

Optimal distributions of central-place foragers: honey bee foraging in a mass flowering crop

Behavioral Ecology, 2022
AbstractThe ideal-free distribution and central-place foraging are important ecological models that can explain the distribution of foraging organisms in their environment. However, this model ignores distance-based foraging costs from a central place (hive, nest), whereas central-place foraging ignores competition.

Effects of maternal age and mass on foraging behaviour and foraging success in the northern elephant seal [PDF]

Functional Ecology, 2013
SummaryAnimals that show indeterminate growth and put relatively constant proportions of stored body reserves towards annual reproductive effort are confronted with a problem of meeting ever‐increasing energetic demands in unpredictable environments.We examined how intrinsic traits, mass and age, as well as extrinsic environmental features impact ...

Mass Fluctuations Suggest Different Functions of Bimodal Foraging Trips in a Central-place Forager [PDF]

Behavioral Ecology, 2012
The function of a foraging trip (self-feeding or provisioning) and the spatial distribution of food resources play an essential role in foraging decisions of central-place foragers. Theory predicts that if foraging patches optimal for self-feeding and provisioning are spatially separated, a bimodal foraging strategy should often be favored.

Photosynthetic Physiological Basis of Forage Mass Stability in a Progeny of Rhizome-Rooted ‘Qingshui’ Medicago sativa L.

Agronomy, 2023
Rhizome-rooted alfalfa (Medicago sativa L.) is an excellent forage for establishing grazing and ecological grasslands, requiring a high and stable yield. Studying the genetic and physiological basis of stable expression of biomass traits is essential for

THE EFFICIENCY OF SELECTION FOR SEED YIELD IN THE FAHL VARIETY OF EGYPTIAN (BERSEEM) CLOVER, Trifolium alexandrinum L. [PDF]

Journal of Plant Production, 2007
Two cycles of modified mass selection and one cycle of family selection were applied on a population of the Fahl variety of Egyptian clover. In 2003/2004, two hundred plants (5% selection intensity) were selected for seed yield, using the modified mass ...

Características da pastagem de azevém e produtividade de cordeiros em pastejo Ryegrass pasture characteristics and lamb productivity in grazing

Revista Brasileira de Zootecnia, 2009
Objetivou-se avaliar a produção da pastagem de azevém, a qualidade da forragem e a produtividade animal por área em três sistemas de produção: cordeiros desmamados precocemente, aos 40 dias de idade, e mantidos em pastagem de azevém (Lolium multiflorum ...

Sward structure and herbage yield of rotationally stocked pastures of 'Marandu' palisadegrass [Brachiaria brizantha (A.Rich.) Stapf] as affected by herbage allowance Estrutura do dossel e produção de forragem em pastagens de capim Marandu [Brachiaria brizantha (A.Rich.) Stapf] sob lotação rotacionada em resposta à oferta de forragem

Scientia Agricola, 2006
In ruminant-forage systems herbage allowance (HAL) has a major impact on grazing intensity and sward structure, affecting animals, plants, and ultimately, pasture yield.
