Dobriner, Rhoads, and Lavin (8, 9) isolated from the excreta of rats injected subcutaneously with 1,2,5,6_dibenzanthracene 1 a phenolic compound which was later shown by Cason and Fieser (3) to have an absorption spectrum identical with that of synthetic 4',8'-dihydroxy-i,2,5,6-dibenzanthracene (Fig. z); the same phenolic derivative was also present in the excreta of mice which had received sim...

The main objective of this study was assessing the level of sanitation and hygiene information and identifying factors that determine its access and utilization by rural households in Alaba District, Southern Ethiopia. The study generated the required data from 162 respondents selected from four rural ‘kebeles’/villages using multistage sampling technique. Both qualitative and quantitative data...

these experiments were conducted to determine metabolizable energy and amino acid digestibilities of soybean meal, sunflower meal and canola meal in broiler chickens by using titanium oxide as indigestible marker in intact or caecectomized cockerels. ileal and total tract digestibility of amino acids were measured using broiler chickens, moreover, digestibility were also determined in the intac...

1 in southern Japan, Bs was added to all broiler feeds (0 or 3x105 CFU/g), and excreta collected at 2 ages. At 14 d, in the Bs ock Lac increased (P<0.05) and Salmonella were not detected vs 4.97 Log10 CFU/g excreta in the negative control ock. At 49 d, Clostridium perfringens (3.22 vs 2.66 Log10 CFU/g excreta; P<0.05) and Salmonella (4.07 vs 3.31 Log10 CFU/g excreta, P<0.01; 20/20 vs 10/20, P...

an experiment was conducted to evaluate the effects of microbial phytase on apparent digestibility of crude protein (cp), amino acids (aa), and apparent retention of calcium (ca), total phosphorus (tp), iron (fe) and zinc (zn) in female broiler chickens diet. the experiment was designed as a completely randomized design. each treatment consisted of 4 replicates of 10 broilers in battery cages, ...

The metabolism of H/C-labeled 4(-deoxy-4(-epimethylaminoavermectin B1a (MAB1a) benzoate, the major homologue (>90%) of the avermectin insecticide emamectin benzoate, was studied in laying chickens. Ten Leghorn hens (Gallus domesticus) were orally dosed once daily for 7 days (1 mg/kg of body weight/day). Eggs and excreta were collected daily, and eggs were subsequently separated into whites and ...

Introduction: About 50 to 70 percent of the waste management total cost is spent on collection operations, so any little progress in reducing collection costs could significantly reduce total costs. This study aimed to analyze the collection and transportation of municipal solid waste cost in Yazd in the next 15 years. Materials and Methods: The study location (five areas) was different urban ...

The metabolism of 3H/14C-labeled 4"-deoxy-4"-epimethylaminoavermectin B1a (MAB1a) benzoate, the major homologue (>/=90%) of the avermectin insecticide emamectin benzoate, was studied in laying chickens. Ten Leghorn hens (Gallus domesticus) were orally dosed once daily for 7 days (1 mg/kg of body weight/day). Eggs and excreta were collected daily, and eggs were subsequently separated into whites...
