The nutritive value of plant species changes throughout the year. For example, the feed value during the vegetative stage of plant growth will be distinctly different to the reproductive (flowering) stage. Environmental conditions can also affect the nutritive value of feed eg frost. These factors need to be taken into account when assessing the value of pasture, crops, fodder and weeds as potential sources of goat feed. A feed analysis will be required to determine the exact feed quality.
