Effect of olfactory stimulation during suckling on agonistic behavior in weaned pigs
نویسنده
چکیده
Materials and methods: Six Control group sows and six treatment (Banana) group sows were used, each with 10 piglets. Treatment consisted of daily topical application of isoamyl acetate (banana scent) on the skin of the sows’ mammary glands during the 21 days of suckling. Preference of the piglets for the banana scent was tested with a V-maze at 4 and 21 days of age. After weaning, pigs were regrouped into groups of 10. For the Banana group, feeders were scented with isoamyl acetate for the 15 days after weaning. During the first 5 hours after regrouping, a video camera was used to record nonagonistic, aggressive, and submissive behaviors. Pigs were weighed on their day of birth and at 21 and 35 days of age. Feed consumed was weighed during suckling and for 15 days post weaning.

Synthetic maternal pheromone stimulates feeding behavior and weight gain in weaned pigs.
One hundred and forty-four pigs were used to determine the effects of a putative synthetic maternal pheromone on behavior and performance of weanling pigs. Each pen of weaned pigs contained three pigs that were given free access to water and feed. Pigs were videotaped in time lapse for 48 h after weaning and weekly body weights and feed disappearances were recorded for 4 wk. Treatments included...
متن کاملEffect of weaning, week postweaning and diet composition on pancreatic and small intestinal luminal lipase response in young swine.
The effects of weaning, week postweaning and diet composition on concentration of lipase in the pancreas and small intestinal lumen were investigated in weanling swine. In Exp. 1, lipase levels were evaluated in suckling pigs from 2 to 35 d of age and in pigs weaned at 21 or 35 d of age. Pigs weaned at 21 d of age were fed a corn-soybean meal diet with lipase levels measured from 3 to 28 d post...
متن کاملInvestigating Effect of Olfactory Stimulation by Vanilla on the Rate of Apnea Attacks in Neonates with Apnea of Prematurity: A Randomized Clinical Trial
Background Apnea of prematurity (AOP) is a developmental disorder that affects the premature newborns frequently. One of the new non-drug methods for controlling apnea attacks is olfactory stimulation. The aim of this study was to determine the effect of olfactory stimulation by vanilla on the rate of apnea attacks in neonates with AOP. Materials and Methods: This study is a single-blind random...
متن کاملImpact of Providing Feed and/or Water on Performance, Physiology, and Behavior of Weaned Pigs during a 32-h Transport.
Transportation at weaning is a complex stressor made up of many factors, including withdrawal from feed and water, which can potentially negatively affect the health and welfare of pigs, especially those already experiencing weaning stress. The objective of this study was to evaluate the effect of weaning and extended transport durations (up to 32 h), with and without the provision of feed and/...
متن کاملGene expression profiling analysis reveals weaning-induced cell cycle arrest and apoptosis in the small intestine of pigs.
In swine production, weaning is a critical event for porcine weaning-associated disease, such as postweaning stress syndrome, which involves intestinal dysfunction. However, little is known about the molecular mechanisms of intestinal dysfunction in pigs during weaning. To gain new insight into the interaction between weaning stress and intestinal function, 4 pigs at 25 d of age for each of the...
