Abstract
Aim:
The objective of the study was to evaluate the effect of deep
litter housing and fermented feed on carcass characteristics and
meat quality of crossbred Hampshire pigs.
Materials and Methods: Forty-eight weaned crossbred Hampshire
piglets of 2 months age (24 males and 24 females) were selected
for the experiment. The piglets were randomly assigned into 4
homogenous experimental groups with 6 males and 6 females each: E 1;
reared on a conventional housing and fed with a fermented diet, E2;
reared on a deep litter housing system and fed with a fermented
diet, E3; reared on a deep litter housing
system and fed with a conventional diet and C; reared on a
conventional housing system and fed with a conventional diet. The
study was continued up to 32 weeks of age and at the end of this
period, 6 animals (3 males and 3 females) from each experimental
group were slaughtered to evaluate carcass traits and meat quality
characteristics.
Results: Pre-slaughter weight, hot carcass weight, and
dressing percentage were significantly (p<0.01) affected by
feeding fermented diet and deep litter housing while carcass
traits, i.e., carcass length, backfat thickness, and loin eye area
were not affected. The edible offal; liver and heart weight
(p<0.05) differed significantly while kidney weight showed no
difference. The inedible offal; head weight (p<0.01) and lung
weight revealed a significant difference (p<0.05) while spleen and
stomach weight showed no difference among the experimental groups.
The wholesale cuts and meat: bone ratio of pigs also differed
significantly among the groups. Morphometry of small and large
intestine also showed a significant difference. Chemical
composition of pork viz., moisture and total ash content
was influenced by the treatment, while crude protein and ether
extract content were not affected. Mineral composition of pork
also showed no significant difference. Color characteristics of
Longissimus dorsi muscle showed a significant difference in L*
and a* value while parameter b* was not affected. The tenderness
of meat showed significant difference among the groups (p<0.01).
Conclusion: Crossbred Hampshire pigs being reared on fermented
feed and deep litter housing could produce highlygraded carcass
and improvement in meat quality.
Keywords: fermented feed, deep litter
housing, crossbred Hampshire pig, carcass characteristics, meat
quality.
