The performance of Ross broiler chickens fed on Sweet Potato Meal (SPM) as a dietary source energy was studied. study carried out at both starter (0-4 wks) and finisher (5- 9 phases. In phases, SPM incorporated graded levels 0. 10, 20, 30, 40 50 percent proteins were adjusted to make the diets iso-nitrogenous. phase, three replicates I5 birds each randomly allocated 6 treatments in completely r...

We studied the osmoregulatory responses of the granivore Zonotrichia capensis, acclimated to highand lowprotein diets as well as two levels of water intake. We tested whether Z. capensis has the ability to modify the proportion of nitrogenous waste in the excreta when protein intake and water intake varies. After 21 days of acclimation, plasma osmolality was not significantly affected by dietar...

Awassi is a multi-purpose sheep breed. Awassi lambs being finished are usually offered an 18% crude protein (CP) diet. The growth rate of Awassi lambs is lower than other meat breeds. Therefore, this high content of dietary CP is questionable. The objective of this study was to estimate the optimum CP level for finishing Awassi lambs. Fifty male Awassi lambs (23.0+/-1.2kg) were fed five high co...

Human male volunteers were studied in a metabolic facility whilst they were fed randomized controlled diets. In eight volunteers there was a significant increase in faecal apparent total N:-nitroso compounds (ATNC) and nitrite excretion (P < 0.0001 and P = 0.046, respectively) when randomized doses of meat were increased from 0 to 60, 240 and 420 g/day over 10 day periods. Mean (+/- SE) faecal ...

OBJECTIVE The aim of this study was to determine the biological effects of natural dietary intake of vitamin K as phylloquinone (K(1)) and menaquinone-4 (MK-4) and a control diet also containing menadione (K(3)) on levels of K(1) and total MK-4 (menaquinone-4) and menaquinone-4-2,3-epoxide (MK-4O)) in liver and pancreas, and on femur bending resistance in a fast-growing animal model. DESIGN C...

There are two general types of metabolism experiments: those of relatively short duration covering several periods, each from a few days to a week in length; and those carried out over as long a period as possible. As examples of the first type we have such investigations as the study of the effect of a given substance upon the nitrogenous equilibrium, or the study of the ability of the animal ...

Forty-eight Suffolk Mule entire male lambs (22.3 kg average live weight, two months old) were used to study the effects of addition of sodium bicarbonate and increasing quantities of molassed sugar beet pulp (MSBP) to diets based on barley grain (780 g kgÿ1 fresh weight and approximately iso-energetic and iso-nitrogenous). Measurements were made of dry matter (DM) intake, growth, some ruminal a...

Dietary cation anion difference (DCAD) is an important aspect of dairy nutrition, especially in the transition period. Sahiwal cattle is the highest milk producing breed among Zebu cattle. We planned first study on transition Sahiwal cattle to determine the effects of feeding varying levels of negative DCAD. For this purpose, twenty pregnant cows (at the 250th day of gestation) were selected an...
