Question

list and discuss the management options that a farmer can use to enable the herd to improve its energy intake?

Explain how the composition of milk from a human differs to that of milk from a whale. What are the likely reasons for these differences?

one of the major limitations of a pasture-based dairy system is feed intake. Using the knowledge that you have gained from lectures and the tutorial to describe why this is the case?

Answer 1

1. Energy intake can change dramatically in response to changes in environmental conditions. One of the major energy saving opportunities in each agriculture fields is improved energy efficiency and uses them wisely to avoid wasting it. There are many opportunities in the deployment of renewable energy systems to displace fossil fuels to provide modern energy.   This gain multiple co-benefits such as in the manufacture of fertilizers, agriculture machineries, cost saving, , improved livelihoods, improved human health, treatment of organic wastes and reduced green house gas emissions.

2. Human milk contains 0.8% to 0.9% protein, 4.5% fat, 7.1% carbohydrates (lactose as major component and lactose-based oligosaccharides as minor component) and 0.2% minerals. Whale milk contains 12.3% to 13.3% protein, 53.4 to 55% water, 31.8 to 38% fat, 0.2 to 0.3% carbohydrates (Lactose) and 1% minerals. Major difference between human milk and whale milk is color. Human milk is white color; whale milk is ream color with a brownish yellow tone. Beaked whale has milk in blue-green in color because of the presence of biliverdin, a pigment in the milk. Blue whales can produce 200 litres of milk per day.

3. One of the major limitations of a pasture-based dairy system is feed intake because a nutritionally balanced supplement should increase the milk production through increased nutrient intake.
