The pineapple extract feed additive ( trade name : Baojia -G ) is a natural plant preparations, in order to explore the the pineapple extract of feed additives on the growth performance and immune function and broiler performance , immune function and succulent flavor impact , the tests conducted feeding trials of weaned pigs , broiler the Hematology immune indicators detect and improve the the chicken quality of the flavor of the effect Experimental Study . In order to verify the pineapple extract feed additives to select a 35 -day-old health weaned piglet production performance and immune function of the test , a similar weight of weaned piglets 63 , were randomly divided into three groups , the comparison test , each group of three repeated each repeat 7 , 7d, of the pre - trial phase of the trial period 30d test 1 : control group fed the basal diet of piglets , and group 2 : The full price of piglets to test three groups : basal diet Baojia - G 500g / t. The results showed that the test group effect best , pineapple extract feed additives can significantly improve the growth performance and immune function of piglets . In order to verify the impact of of pineapple extract feed additives on broiler performance and immune function and succulent flavor , the test selected 400 broiler chicks were randomly divided into four groups ((Ⅰ , Ⅱ group , Ⅲ group , Ⅳ group) , n = 100 ( equipped with five replicates , each repeated 20 ) were fed blank feed , basal diet of conventional feed , ensure good -G 0.5kg / t the Baojia - G 1.0kg / t basal diet test chicken ground level raising manner for a period of a 70d feeding trials , during the test temperature , humidity and light natural conditions and supplemented by artificial conditions , fed ad libitum and drinking water , disease prevention and treatment by conventional methods . experimental results show that , with the blank The group , comparison between the conventional group , the Baojia - G high dose group , low dose group Baojia - G can significantly improve the performance of broiler production , immune function and improve meat quality and flavor . thus proving pineapple extract feed additives in improving weaned piglets improve broiler and broiler performance , meat quality and flavor , and improve immune functions play an important role , which opened up a new way for hog and broiler antibiotic alternative .
