Small animals tend to expire sooner than related large ones if forced to live on

Question

Small animals tend to expire sooner than related large ones if forced to live on stored supplies. For instance, suppose you have a mouse and a dog that both start with body stores of fat equal to 20% of body weight. Explain why the mouse would be likely to die sooner if these animals could not find any food and thus had to live on their fat reserves. Which would one die sooner if they were trapped underwater and had only their stores of O_2 to live on while trying to escape? Suppose that over a period of 4 h a dog was observed to consume O_2 and produce 14 L of CO_2. Using Tables 7.1 and 7.2, estimate the dog's total heat production over the 4 h. Explain why Table 7.2 is essential for your calculation. Poultry scientists are doing research on the design of diets that nutritionally complete for chickens but minimize the SDA. helpful to the believe that such diets would be particularly of summer. Poultry in southern states during the heat Why might this be true? Before Mayer and Joule came along (see Box 7.1), people were well aware that if a person cranked a drill, heat appeared. For instance, the drilling of the bores of cannons was legendary neither heat, However, heat per se was believed to be motion created nor destroyed, and thus no one thought that the go associated with drilling turned into heat. Mayer and Joule in down history in part because they demonstrated the real relation between motion and heat. Imagine that you were alive in the early nineteenth century, and like Mayer and joule, you

Explanation / Answer

Poultry scientists have found that the poultry tissues or the meat and eggs produced thereform can be improved through the utilization of transgenic soyabean oil comprising stearidonic acid("SDA") in minimal feed.Specifically, it was found that its utilization in feed products improves the nutritional quality of poultry derived products or in the productivity of the animals themselves

Furthermore ,there was a great incorporation of SDA into poultry meat when using the SDA soyabean oil as compared to using the SDA ethyl ester .More particularly ,it has been found that pancreatic lipase resistance results in lower absorption of fattyacids in humans.It is belived that this lipase resistance results in lower absorption of SDA into the poultry when using SDA ethyl ester as compared to SDA soyabean oil.

In research it was found that the natural stearidonic acid found in the native soyabean is genitically modified to a elevated level in such soya bean as compared to the levels of stearidonic acid found in native soyabean.

The SDA may be combined with grains corn , wheat, barley , oil seeda meals such as soyabean meal, cottonseed meal, flaxseed meal, canola meal The effect of feeding diets containing stearidonic acid modified soyabean oil on n-3Fatty Acid deposition in Broilers.The purpose of this study was to determine the extent to which omega - 3 Fattyacid were enriched in chicken meat when birds are fed with SDA

Inclusion of fats in the diet should be considered on hot days,particularly for broiler chickens, inorder to maintain daily energy intake in line with the requirements for growth.On many tropical farms ,it is a common practice to exclude fat from the diet during summer and include it during winter.It is though,that the energy requirements of broilers is less in summer than in winter.
