The aim of this study was to evaluate effects of alfalfa and fructooligosaccharides (FOS) on molting performance and bone parameters compared with the conventional feed withdrawal molting procedure. A total of 36 Single Comb White Leghorn hens (84 wk of age) were used for this experiment. The hens were divided into 6 treatment groups with 6 birds per treatment: pre-trial control (PC), full fed ...

The effects of dietary energy source and feed withdrawal on muscle glycolytic potential (GP) and blood acid-base responses to handling were investigated in slaughter-weight pigs (initial BW 94.7 ± 1.01 kg). Crossbred pigs (n = 96; 48 barrows, 48 gilts) were used in a randomized complete block design with a 4 × 2 × 2 factorial arrangement of treatments: l) diet [control, high fat (10% supplement...

Broilers are withheld from feed for 8 to 24 h before processing to empty the gastrointestinal tract and reduce potential carcass contamination from gastrointestinal tract contents. Intestinal microbial changes during feed withdrawal (FW) have not been thoroughly defined. Two experiments were conducted to examine the effects of diet and FW on the microbial ecology in the small intestine. In expe...

Rice is an essential crop in Iran that is grown mostly in areas where depth to groundwater is low. Root growth and water uptake of rice under shallow groundwater has not been thoroughly studied. This experiment was conducted to determine the lowland rice (cv. Ghasrodashti) root distribution above shallow groundwater in relation to deficit irrigation and groundwater depth in cylindrical gre...

Commercial broilers are exposed to a number of stressors prior to slaughter, including feed deprivation, crating density (high vs. low), and transportation. Hence, the individual and additive or overruling effects of these stressors on welfare and energy metabolism were examined. Live weight gain, rectal temperature, physiological responses, and meat quality of broilers were determined. The fas...

The crop is a known source of Salmonella and Campylobacter contamination. We evaluated the use of selected organic acids (0.5% acetic, lactic, or formic) in drinking water during a simulated 8-h pretransport feed withdrawal (FW). Salmonella typhimurium was recovered from 53/100 control crops and from 45/100 of crops from acetic acid-treated broilers. However, treatment with lactic acid (31/100)...

introduction the commercial egg industry commonly uses induced molt procedures to rejuvenate flocks for a second or third laying cycle. molting may be induced by feed withdrawal for up to 10 days (7), water withdrawal for 2 days (19), or both, along with a reduction of day length (14). such programs cause concern about animal welfare because it is thought that they may be harmful to hens (28). ...

Preterm infants have higher nutrient requirements than term infants. Enteral tube feeding is the preferred route to feed preterm infants because premature infants are unable to coordinate sucking, swallowing, and breathing. There are two common tube feeding methods: intermittent (bolus) or continuous infusion. Minimal enteral nutrition or trophic feeding has many advantages for preterms and sho...
