Supplementation of a basal corn-soybean meal diet with 0 or .2% L-lysine and 0, .25 or .55 ppm biotin produced six dietary treatments in a factorial arrangement. Pig performance, post-weaning scour scores, plasma urea N (PUN) levels, N and energy balance and liver pyruvate carboxylase activity (PC) were response criteria. Crossbred pigs were fed from weaning at 4 wk of age (8.0 kg) to market we...

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....

Two trials were conducted to study the effect of inclusion of hull-less barley and exogenous enzyme to broiler diet on the growth performance, apparent metabolisable energy (AME) and Nutrient digestibility of broiler chickens. The experiments were 3×4 factorial arrangements with three levels of enzyme (0, 300 and 600 g/ton) and four levels of hull-less barley inclusion (0, 10, 20 and 30%) in di...

The main goal of the current study was to investigate effects feeding low protein (LP) diets on performance parameters and excreta composition broiler chickens. In total, 288 male Ross 308 day-old chickens were divided into two dietary treatment groups using six replicate pens with 24 each. No LP diet fed in starter phase. reduction grower finisher phases 1.8% 2% respectively. Beside measuremen...

Massive amounts of pig manure are produced by intensive pig farm in China, and the composition of pig manure has changed much due to the use of feed additives. However, little is known about the exact Cu (copper) feed as additives or present as contaminants in pig feed and the residues in feces. One hundred and thirty-seven feeds and one hundred and forty-two fecal samples from 48 pig farms wer...

an experiment was conducted to evaluate the effect of withdrawing vitamin and/or trace mineral premixes from grower and finisher diets of broilers. a 2×4 factorial arrangement of treatments, consisting of four diets and two-removal times (from 28 to 49, and from 35 to 49 days of age) was utilized. the four diets consisted of control, supplemented with vitamin (vit) and trace minerals (tm)(t1); ...

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...

to evaluate antioxidant effects of tomato pomace in broiler diets contained full-fat linseed on the production index, energy and protein efficiency, 396 one-day old ross 308 broilers were randomly allocated to 36 cages for nine dietary treatments with four replicate. this experiment were carried out in a completely randomized design with 3*3 factorial arrangement with three levels of full-fat l...
