Techniques Applicable to Grazing Intake Studies

چکیده
TWO methods of estimating pasture intake from total faecal output are discussed. Dry matter indigestibility co-efficients (apparent) are useful where the range of inter-species digestibility is relatively narrow in any one seasonal period. A relationship between total faecal nitrogen excretion and dry matter intake is illustrated and the biological principles upon which this type of relationship depends are discussed. It is concluded that a number of separate regression relationships may improve the accuracy of the estimation.

Nigeria is one of the most malnourished and hunger ridden in the league of developing countries; according to reports of Food and Agricultural Organization (FAO) of United Nations estimated daily animal protein intake for developing countries averaged at 4.5 g/head/day at the beginning of this century which has hardly risen to 10 g/head/day into the second decade of the century in Nigeria. This...

Successful pasture-based milk production systems pivot on balancing dairy cows’ feed requirements with seasonal and annual fluctuations in pasture production. In order to maximise cow production from grazing dairy systems, it is necessary to reach an efficient utilization of grazed grass for feeding cows and the development of appropriate grazing management systems designed to maximize daily pa...

Four techniques were compared for their ability to estimate forage dry matter intake (DMI) of grazing animals. In the Cage technique, 10 grazing cages were placed within each pasture, and forage inside and ou...
متن کاملPredicting Forage Intake by Grazing Ruminants
Determination of the amount eaten and characteristics of the diet of grazing ruminants remains one of the most difficult tasks in research. While several lifetimes have been devoted to developing techniques to ‘measure’ intake and diet quality, they are laborious, expensive, and often lack both precision and accuracy. Hence, there has been little effort on the part of producers or consultants t...
متن کاملResearching the plant-animal interface: the investigation of ingestive behavior in grazing animals.
Profitable livestock production from forages largely depends on efficiency of converting forages into products. Efficient grazing management systems require an understanding of the roles of system components. However, experimentation should be conducted with regard to the system as a whole rather than on the systems components in isolation. This may necessitate development of computer models. T...
