Brazil is a major pork producer, with increasing market demands driving heavier slaughter weights. Sexual condition well stablished factor influencing pig performance, carcass composition, and quality, previous studies focusing primarily on lighter pigs. This study compared the characteristics, traits of heavy-slaughtered barrows gilts. A total 144 pigs (72 barrows; 72 gilts), an average weight 55.68 ± 6.48 kg, were utilized in randomized complete block design. They allocated into 48 pens...
Abstract The objective of this work was to evaluate the effect a farrowing unit with an adiabatic evaporative cooling system negative pressure and longitudinal air flow on catabolism performance lactating sows. Twenty eight multiparous sows were housed in system. During 24 days lactation, animals submitted two treatments: pad cooling, close system, exhaust, exhaust fans. microclimatic variables temperature humidity, as well intake, body condition score, litter weight, which indicate...
Abstract Supplementing swine diets with phytase increases phosphorus release by approximately 50% from cereal phytates. The increase in availability allows for a reduction dietary supplementation mineral sources and decreases the environmental impact of pork production through decrease excretion. Superdosing has been reported to boost productivity, improve digestibility other nutrients, mitigate antinutritional effects However, there are significant cost differences among products. Bacterial...
The objective of this study was to evaluate the effects creep feeding during pre-weaning stage on performance piglets at nursery phase, as well estimate economic viability its application. A total 125 were exposed and evaluated qualitatively regarding diet intake quantitatively weight gain. After determining eaters non-eaters' piglets, 48 these animals in phase. Piglets are blocked (initial weigh sex) divided into (E, n=24) non-eaters (NE, n=24). Time start feed intake, growth data analyzed....
