The release of pathogens into the air from swine confinement buildings are mitigated through preventative measures, such as outgoing air filtration, to reduce the risk of spread to nearby barns and communities. The present study aims to characterize the effectiveness of a percolating biofilter developed by the Research and Development Institute for...
Intramuscular fat (IMF) content is an important economic trait for pork quality. Our previous results regarding the genome-wide association between IMF content and copy number variations (CNVs) indicated that the CNV within Netrin-1(NTN1-CNV) was significantly associated with IMF. In order to validate the effect of NTN1-CNV, we detected the Netrin-...
The aim of this study was to determine, in swine, what are the consequences of heat exposure during most of gestation on the development of stress response systems in the offspring. For this purpose, pregnant sows were housed at thermoneutrality (TN, 18-24 °C, n=12) or in heated rooms (HS, 28-34 °C, n=12) from the 7th (G7) to the 106th day of gesta...
Put simply, with pig nutrition management, we aim to maximize output for minimal input, both in terms of litter size and subsequent pig growth rate. Food is the most important resource for pigs, and pigs will use aggression to gain or protect food. Naturally, pigs are designed to have gradual exposure to solid feed and wean late, and eat numerous m...
The human-pig relationship develops through visual, tactile, olfactory, and auditory interactions. Our objective was to determine the effect of human voices on the development of the human-pig relationship. We hypothesised that human voice facilitates human-pig relationship development and handling. We studied the behaviour of 90 weaned female pigl...
Pre- and postnatal development of adipose depots in meat animals with a specific focus on the pig. 65. International Congress of Meat Science and Technology (ICoMST)
A strictly anaerobic, Gram-stain-positive, catalase-negative, non-motile, rod-shaped bacterium, designated SG0102T, was isolated from the small intestine of a swine. Optimal growth occurred at 37°C and pH 7.0. Furthermore, growth was observed in the presence of up to 3% (w/v) NaCl but not at salinity levels higher than 4%. The comparative analysis ...
The present study aimed at predicting feed efficiency (FE) based on fecal microbiota, using partial least square regression (PLSR), sparse PLSR, and random forest regression (RF). Fecal samples from 147 Pietrain x (Large White x Landrace) pigs reared in two consecutive batches were collected at 99 days of age. Daily live body weight and feed intake...
The present study aimed at describing the impact of a deoxynivalenol (DON) - contaminated diet on microbiota composition.A total of 147 (Large White x Landrace) x Piétrain pigs from two replicates were affected to four different experimental treatments. Pigs in the control group (CC) received a control diet from 99 to 154 days of age. Groups DC, CD...
