The objective of this study was to determine the optimal inclusion rate of dietary formic acid-ammonium formate (composition by weight was 62% formic acid and 37% ammonium formate) in nursery and grower-finisher diets or grower-finisher diets only. At weaning (d 21 +/- 2), 224 pigs (equal numbers of gilts and barrows) were blocked by BW within sex (28 pigs per BW block, 4 pigs per pen) and assi...

This study was conducted to evaluate the effects of lavender (Lavandula angustifolia)extract as an alternative to flavophospholipol on performance, carcass characteristics, antioxidant status,meat quality, intestinal morphology and ileal microflora of broilers. A total of 220 day-old male broiler chicks (Ross 308) were used in a completely randomized design with five treatments each re...

A 2×3 factorial arrangement of treatments was used in a completely randomized design to determine the effects of dietary Zn on performance and immune response of acutely endotoxemic growing pigs (n=96, mean BW=24.9 kg). Factors included 1) intramuscular injection of 10 μg/kg BW of Escherichia coli lipopolysaccharide (LPS) or control and 2) supplemental Zn at 10, 50, or 150 ppm. Diets were fed b...

Three experiments were conducted to determine the digestible lysine requirement of starter (6 kg BW initially) and of grower (21 kg BW initially) pigs. Experiment 1 used 294 starter pigs and lasted 28 d; Exp. 2 used 182 grower pigs and lasted 35 d. Protein and total lysine contents of the basal corn-peanut meal diets were 20 and .8% for Exp. 1 and 16 and .54% for Exp. 2. Basal diets were fortif...

A trial was conducted to determine the effect of low-protein diets with constant ME:CP ratio on performance and carcass characteristics of broilers from 1 to 35 d of age. Four experimental diets were formulated to have 4 levels of CP and ME, respectively, in each phase: 23, 22, 21, and 20% CP with 3,036, 2,904, 2,772, and 2,640 kcal/kg in the starter phase (1 to 10 d); 22, 21, 20, and 19% CP wi...

an experiment was conducted to evaluate the effects of dietary crude protein (cp) and lysine levels on performance and nitrogen excretion in broiler chickens. four hundred twenty 7-day old chickens from ross 308 strain were randomly allotted to 6 dietary treatments with 5 replicates of 14 chicks each (7 male and 7 female chicks). the cp levels were 17, 18, and 20 percent and lysine levels were ...

The effects of feeding various dietary Ca:P level sequences on gain and feed efficiency, leg structural soundness and bone indices of growing-finishing swine were evaluated as an incomplete 3 X 3 factorial arrangement of treatments in a split-plot design. A total of 664 pigs were fed one of three total dietary Ca:P levels (.52:.40, .65:.50, .80:.60%) from 19-kg to 56-kg body weights followed by...

The current study evaluated the effect of a commercial wheat-maizesoybean meal based diet supplemented with an organic acid product containing a specific combination of formic and propionic acids (pHorce) on performance parameters in broiler chickens. One day-old broiler chickens (Ross 308) were randomly allotted to 2 treatments with 10 replicate cages/treatment and 2 birds/cage from d 1 to 21....
