From a total of 656 broiler farms with the permission of exploitation in Guilan province, data was gathered from 20% of active farms including 85 units (Capacity of over 1663000 portions of broiler chickens) to evaluate the management of nutrition and nourish using questionnaire. The questionnaires were completed by the interview method. The methods of making feed, feed formulation, the shape o...

Cows will typically experience a 30 to 35% reduction in feed intake during the final two to three weeks prior to calving. Blood fatty acids at calving are negatively related to feed intake and positively related to incidence of postpartum metabolic disorders. Feed and manage cows to maximize feed intake during the transition period. Over conditioned cows are likely to have poor appetites, but d...

This experiment aimed to describe the effects of Oregano extract (OE) inclusion into the concentrate fed to dairy heifers on physiological parameters, feeding behavior, intake, and performance. Thirty-two Holstein heifers were randomly distributed into four treatments: C = control, without addition of OE; OE2.5 = 2.5 g; OE5.0 = 5.0 g and OE7.5 = 7.5 g of Oregano extract per heifer/day. Feeding ...

Commercial porcine factor VIII concentrate (Hyate:C) is effective in treatment of patients with hemophilia A who have circulating antibodies to factor VIII. The molecular forms of factor VIII in the concentrate were identified and evaluated in light of the known properties of porcine and human factor VIII. The factor VIII in the concentrate was isolated by tandem chromatography on gelatin-Sepha...

Rising populations and incomes throughout the world have boosted meat demand by over 75% in the last 20years, intensifying pressures on production systems and the natural resources to which they are linked. As a growing proportion of global meat production is traded, the environmental impacts of production become increasingly separated from where the meat is consumed. In this paper, we quantify...

T w o finishing trials were conducted to measure the response of cattle adjusting to high-concentrate diets to dietary monensin level. In trial 1, 54 individually fed Hereford-Angus steers (312 kg), previously fed a two-thirds corn silage: one-third corncob-based diet, were allotted in a 2 • 3 factorial arrangement of treatment with tylosin (0, 11 mg/kg) and monensin (0, 11, 33 mg/kg) fed durin...

This experiment was conducted to study the eff ects of dietary addition Pluchea indica L. leaf meal on performances and meat cholesterol content of broiler. One hundred sixty two DOC CP707 strain were reared for four weeks in high stocking density of 15 birds/m2. The birds were fed experimental diets consisted of R1 (commercial feed + Vitastress), R2 (commercial feed + 2% P. indica leaf meal), ...

The abundance of six tetracycline resistance genes tet(O), tet(Q), tet(W), tet(M), tet(B) and tet(L), were quantified over time in wastewater lagoons at concentrated animal feeding operations (CAFO) to assess how feedlot operation affects resistance genes in downstream surface waters. Eight lagoons at five cattle feedlots in the Midwestern United States were monitored for 6 months. Resistance a...
