Frequency distributions of sward height under sheep grazing
Grass and Forage Science, 2005 AbstractCattle and sheep can create and maintain a mixture of relatively tall and short patches in grass swards through selective grazing. In swards that are grazed by cattle this heterogeneous structure can result in the frequencies of height measurements having a skewed distribution that has variously been better described by the double‐normal ...

Research Note:Precision and accuracy of sward height distributions
African Journal of Range and Forage Science, 2007 Double normal distributions can be used to resolve many sward height frequency distributions into two components representing the 'short' (patches) and 'tall' (non-patches)areas in the sward. The effect of sample size on the precision and accuracy of parameters of sward height distributions was examined by drawing sub-samples (n = 10) of increasing ...

The effect of litter size and sward height on ewe and lamb performance
New Zealand Journal of Agricultural Research, 2004Abstract This study compared ewe and lamb performance in twin‐ and triplet‐bearing/rearing ewes offered varying sward heights from day 64 (P64) of pregnancy until weaning at day 87 (L87) of lactation. Ninety‐six twin‐ and 90 triplet‐bearing Romney ewes were randomly assigned on P64 to four replicated sward height ...

Variation of pecking rate with sward height in wild wigeon Anas penelope
Journal of Ornithology, 2006 We examined how pecking rate changed with sward height in wintering European wigeon Anas penelope in a nature reserve of the French Atlantic coast. Pecking rates were recorded as the time taken to perform 10 or 50 pecks. We found a negative correlation between pecking rate and sward height over a range of heights from 1.0 to 3.5 cm, but no sex effect ...
