Numerous stressors such as environmental, nutritional, pathological or equipment related ones are operative in swine facilities. Among many factors, socking density increases social stress and influences pig performance. Many studies have reported that reducing space allowance could induce...

This study was conducted to evaluate the effects of dietary vitamin levels and stocking densities on growth performance, nutrient digestibility, and blood characteristics in growing pigs. A 2×3 factorial (two vitamin levels, three regimens of stocking densities) arrangement was utilized with 96...

Background/aim: The condition of footpad is an important aspect of poultry welfare. This is a problem that plagues the poultry industry because it occurs whether birds are reared in the cage or on the floor. It is reported that feeding phytase to floor-reared broiler chicks could ameliorate footpad ...

The present study evaluated the optimal duration of creep feeding that improves the growth performance and fecal score of piglets and the performance and estrus interval of sows. Sixteen sows (Yorkshire × Landrace) and their litters were used in this 24-day trial. Dietary treatments were: Treatment ...

This study aimed to evaluate the effects of spraying microbial agents in pig slurry and housing on harmful gas emissions. A total of 300, eightweek- old crossbreed ([Yorkshire × Duroc] × Landrace) growing pigs, with an average body weight of 28.2 ± 0.55 kg were used in this trial lasting 4 weeks...

A total of 144 mixed sex pigs [(Landrace × Yorkshire) × Duroc] with an initial average body weight (BW) of 52 kg were used in a 11 wk trial in a 2×2 factorial design with the following factors: group size (three pigs per pen vs. five pigs per pen) and 0% or 0.2% homeopathic product supplementation...

The study was conducted to determine the interactive effects of creep feed and different weaning age of piglets on the production performance of lactating sows and performances of piglets. Our study indicated that the piglets provided with creep feed led to a higher BW, ADG at nursery and weaned...

Weaning is one of the most stressful events in the pig's life, which disrupts physiological balance and leads to oxidative stress. It is reported that glucose oxidase supplementation could alleviate oxidative stress in animals by increasing the concentration of antioxidant enzymes in vivo. The...

A total of 90 finishing pigs (52 ± 1.46 kg) were randomly assigned to one of three dietary treatments as: TRT1 [CON (basal diet)], TRT2 [CON + 0.05% yeast hydrolysate (YH)], and TRT3 (CON + 0.1% YH) for an 8 wk trial. Each treatment had six replications and five (three gilts and two barrow) pigs...

A total of 360 one-day-old broiler chicks were randomly assigned to four treatments with five replicate cages and 18 birds per cage for a 35 d trial to investigate the effects of supplementing Achyranthes japonica Nakai (AJN) root extract in low crude protein (CP) diet on growth performance and...
