a study was conducted to evaluate the effect of feeding different levels of protein to black baladi breed kids. weanling baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. kids were divided randomly to one of the three treatments for 12 weeks. the three dietary treatments were: t1: control ration, formulated according to nrc to cover the protei...
Because of competitive interactions in the metabolism of polyunsaturated fatty acids, tissue and bodily requirements for each of the three dietary essential fatty acids in marine fish, 22:6n-3, 20:5n-3 and 20:4n-6, cannot be meaningfully considered in isolation. Rather, it is necessary to consider requirements in relative as well as absolute amounts, i.e. in terms of the ratio of 22:6n-3 : 20:5...
changes in dietary electrolyte balance influence the metabolic fate of protein and many amino acids. furthermore, acid-base condition is achieved in part by the alteration of dietary amino acids pattern and quantity. therefore, a trial was conducted in a completely randomized design to evaluate performance, carcass characteristics, plasma electrolyte and uric acid concentrations of 19 and 28-da...
the hypothesis of this experiment was that the various sources of dietary fat with different dietary ratios of polyunsaturated fatty acids (pufas) to saturated fatty acids (sfas) would alter the reproduction parameters of mature rams. twelve mature rams were randomly allotted to one of four dietary treatments in a completely randomized design. dietary treatments were: 1) ration with 4% soybean ...
Most models developed for poultry are linear to the point where genetic potential is reached. Models reliant on the premise that growth rate determines requirements based on some fixed rate of nutrient utilization do not adequately represent the biological phenomena involved. Therefore, a dichotomy between the accepted theories of nutrient utilization in animals and the assumptions of mathemati...
The Daniel Fast is a biblically inspired dietary program rich in carbohydrate, most closely resembling a vegan diet but with additional restrictions, including the elimination of processed foods, white flour products, preservatives, additives, sweeteners, caffeine, and alcohol. While no specific requirements are placed on the ingestion of specific percentages of macronutrients, the mean daily c...
All vertebrates require certain amounts of energy, protein and ‘essential’ nutrients. Dietary sources of energy include carbohydrates, protein and fat. Dietary protein is necessary for satisfying an animal’s protein requirements. Certain dietary nutrients are classified as ‘essential’ because they are required for synthesis or functioning of crucial chemical compounds, yet they cannot be synthe...

In separate experiments the isoleucine and leucine requirements of the kitten were determined on the basis of growth and nitrogen retention. The dietary concentrations of isoleucine tested were (g/kg diet) 1.4, 2.2, 3.0, 3.8, 4.6 and 9.0 with adequate (12.0 g/kg diet) leucine. The levels of leucine tested were (g/kg diet) 5.0, 7.5, 9.0, 10.5, 12.0 and 20.0 in diets containing adequate (9.0 g/kg...
