Two experiments were conducted to determine the efficacy of mannan oligosaccharides (MOS) fed at two levels of Cu on growth and feed efficiency of weanling and growing-finishing pigs, as well as the effect on the immunocompetence of weanling pigs. In Exp. 1, 216 barrows (6 kg of BW and 18 d of age) were penned in groups of six (9 pens/treatment). Dietary treatments were arranged as a 2 x 2 fact...

The present study was performed to investigate the effects of two groups of sires with 'medium' and 'high' weight gain potentials (M-sires and H-sires, respectively) on growth of their progenies on varying planes of nutrition during the growing-finishing period. The ADG of the M-sires' progeny was greater (P < 0.05) than that of the H-sires' progeny (0.51 vs. 0.47 kg) during a 26- to 29-d early...

Acute and sustained soluble dietary fibre (SDF) consumption are both associated with improved glucose tolerance in humans and animal models (e.g. porcine). However, the effects on glucose tolerance in grower pigs, adapted to diets with a combination of SDF have not been studied previously. In this experiment, cereal SDF wheat arabinoxylan (AX) and oat β-glucan (BG) were fed individually and in ...

Oral cancer is a highly lethal disease and one of the most debilitating and disfiguring of all malignancies in the world. According to Global Adult Tobacco Survey (GATS) 2010 report, 60% of tobacco users in India use only smokeless tobacco. Among 206 million smokeless tobacco users, 65.1 million are consuming gutkha. In recent years, gutkha is recognized as a life threatening disorder with the ...

Background: Smoking is the largest preventable cause of death in the world, killing nearly 6 million people annually. This article is an investigation of measures implemented laws in the Iran to study the proposed strategy of control and reduce tobacco use based on the monitor, protect, offer, warn, enforce and raise (MPOWER) policy.Methods: All laws approved by the Parliament along with the in...

the present study was conducted to investigate the effect of corn substitution with triticale in grower diets (zero, 50 and 100%) with/without exogenous enzyme supplementation on growth performance, digestive organs relative weight, jejunal morphology and blood lipids of quail chicks. two hundred and forty one-day-old unsexed japanese quail chicks were randomly assigned to a completely randomiz...

This study was conducted to investigate the effects of feed withdrawal on the viscera of commercial broilers. Birds were withdrawn from feed 0, 3, 9, 12, 14, 16, or 18 h before slaughter. Crop and gizzard contents were determined after dissection, and intestinal shape and villi were subjectively scored. Raw liver color was measured colorimetrically. Length of feed withdrawal (time) and its inte...

A study was conducted to evaluate the use of constant or increasing levels of Distillers Dried Grains with Solubles (DDGS) in diets for broilers. Diets were formulated for starter (0-14 d), grower (14 to 35 d) and finisher (35 to 42 d) periods to contain 0, 15, or 30% DDGS. Diets were formulated on digestible amino acid basis to meet current U.S. poultry industry nutrient levels and were mainta...

A total of 252 crossbred pigs were used in two experiments to determine the effect of feeding hydrolyzed feather meal (FM) during the growing-finishing period on animal performance, carcass composition, and pork quality. All pigs were blocked by weight, and dietary treatments were assigned randomly to pens within blocks. In Exp. 1, 24 pens were randomly assigned to one of three dietary treatmen...

A recent study has shown that sorting and regrouping lightweight pigs with pigs of similar size does not improve their growth performance and carcass characteristics. M. C. Brumm and coworkers (2002) hypothesized that managing variation in the nursery and grower-finisher by sorting and regrouping lightweight pigs might improve their performance. Five experiment stations (in Illinois, Iowa, Mich...
