Food crops have a strategic role in agricultural development, covering food security growth, opening up employment opportunities, and income sources regional national economies. This research aims to determine the relationship patterns of sweet potato farming production factors. utilized quantitative approach with survey method. The data were obtained through questionnaires, sampling method use...

Serotonin is known to regulate energy and calcium homeostasis in several mammalian species. The objective of this study was to determine if pre-partum infusions of 5-hydroxytryptophan (5-HTP), the immediate precursor to serotonin synthesis, could modulate energy homeostasis at the level of the hepatocyte in post-partum Holstein and Jersey dairy cows. Twelve multiparous Holstein cows and twelve ...

The effects of apple pomace diets on rumen microbial population, movement of ingesta from the rumen, and water intake were studied in two trials with beef steers. Trial 1 was a 5 • 5 Latin square in which five ruminal fistulated steers were fed either corn silage plus cottonseed meal (CSM), apple pomace plus CSM, apple pomace plus urea, apple pomace plus urea and starch, or apple pomace plus ur...

It has been previously demonstrated that the hepatic level of each enzyme concerned with the biosynthesis of urea in the rat, i.e. carbamyl phosphate synthetase, ornithine transcarbamylase, argininosuccinate synthetase, argininosuccinase, and arginase (see Ratner (1) and Cohen and Brown (2) for discussions of the enzymatic steps of urea biosynthesis and general problems of urea synthesis), bear...

We studied the effects of supplementing N as distillers dried grains with solubles (DDGS) or urea to steers consuming corn-based diets. Six ruminally and duodenally cannulated steers (244 kg) were used in 2 concurrent 3 x 3 Latin squares and fed 1 of 3 corn-based diets: control (10.2% CP), urea (13.3% CP), or DDGS (14.9% CP). Periods were 14 d, with 9 d for adaptation and 5 d for collection of ...

A method for measuring urea production by isolated erythrocytes and leucocytes under physiologic conditions is described. Erythrocytes from 10 normal subjects formed an average of 82.5 mmoles urea/mi. packed cells/hr. Leucocytes formed 7.4 mmoles urea/108 cells/hr. By extrapolation, total urea synthesis by circulating erythrocytes would be approximately 270 mg./day and by the granulocyte pool a...

The losses of nitrogen (N) fertilizer applied to the soil microenvironment reduce its efficiency. Different strategies like use polymer coating and chemical nitrification inhibitors had been employed N losses. But these are very expensive. Thus, a study was conducted investigate effects different concentrations Parthenium extract, neem oil, acidulated cow dung compost extract on dynamics in soi...

An experiment was conducted to study wheat grain protein increasing through foliar application of Nitrogen afterflowering. The RCBD design was analysed with three replications and four N-treatments as foliar application as(N0=0, N1=4kg.ha-1 Urea, N2=8kg.ha-1 Urea, N3=4kg.ha-1 Ammonium Sulfate). Results showed that seed proteincontent increased significantly by foliar application of Nitrogen. Da...
