Phosphorus Nutrition in Ruminants Grazing Tropical Rangelands

Autor: Rob Dixon, Stephen Anderson, Lisa Kidd, Mary Fletcher

Publikováno v: Proceedings, Vol 36, Iss 1, p 200 (2020)

Nutritional deficiency of phosphorus (P) is a major constraint to productivity of cattle grazing many tropical rangelands with low P soils, particularly in northern Australia, South America and Africa. Cattle growth and reproductive rates may be seve

In smallholder crop–livestock systems where maize (Zea mays L.) is a staple cereal, the stover is usually an important but low-quality ruminant feed. Maize stover has various competing uses, and optimal allocation of stover, particularly for forage

Effects of a nitrogen-based supplement on intake, live weight and body energy reserves in breeding Bos indicus cross cows

Autor: R. Mayer, Rob Dixon

Publikováno v: Tropical Grasslands-Forrajes Tropicales. 9:70-80

Breeding cows grazing seasonally dry rangelands usually lose substantial live weight (LW) during the dry season, when in late pregnancy. An experiment investigated the effects of feeding a N-based supplement to cows in late pregnancy on voluntary int

Alternative rib bone biopsy measurements to estimate changes in skeletal mineral reserves in cattle

Autor: Rob Dixon, D. B. Coates, C. P. Miller, R. Mayer

Publikováno v: Animal, Vol 13, Iss 1, Pp 119-126 (2019)

Rib bone biopsy samples are often used to estimate changes in skeletal mineral reserves in cattle but differences in sampling procedures and the bone measurements reported often make interpretation and comparisons among experiments difficult. ‘Full
