Abstract
Sorting and rearing of pigs on equal weight basis is one of management options used in improving the welfare of pigs. A sixteen-week study was carried out to investigate the serological responses, tibia bone characteristics and gut morphology of pigs to weight asymmetry. Fifty-four Large White growing pigs (15.33±0.2 kg) were assigned to three treatments (Homozygous heavy, homozygous light and heterozygous weights) with 18 pigs per treatment, further sub-divided into 6 replicates with 3 pigs per replicate. On 16th week of the experiment, one pig per replicate group was selected, fasted and sacrificed. Blood samples, sections of the gut (duodenum. jejunum and ileum) and tibia bone were collected for the assessment. Data generated were subjected to 1-way analysis of variance using SAS (2003) package. The results showed that total protein, albumin, total cholesterol, high density lipoprotein and aspartate aminotransferase were significantly influenced by weight asymmetry. Weight asymmetry had positive impact on duodenum villus height and ileum lamina propria depth of the pigs. Wet bone weight, bone length, medial thickness and lateral thickness of the tibia were also influenced by weight asymmetry. It was concluded that weight asymmetry had positive impact on some serological parameters, gut and tibia bone characteristics of pigs.
