Application Effect Research Of Combination Of New Phytoextraction Sweetener And Colostrum Flavor?Flavor Enhancer On Weaned Piglets

EWS is an important factor to restrict the production of pig farming.It can decrease the piglets' intake of feeding,growth performance,growth rate and slow down the growth of piglets,which has a great impact on the eff-iciency of pig farming.Adding flavor agents in piglets' diets can improve the piglets' intake and relieve them from the EWS.The research includes three experiment.The results of the research would offer a theoretical basis for the study of the new sweeteners,sweet,fresh and sweet composite compound the agent on weaned piglets' EWS.Trial one:The effects of different levels of PES on weaned piglets.The experiment has two parts.36 piglets,whose age were 24-days-old,were used in test(1).These piglets were randomly divided into 3 groups,each group has 4 replicates,and in each replicate there are 3 piglets.The test lasted 5d.The control diet is the basal diet,which didn,t add any flavor agents.The piglets in test groups of A?B?C were feed with test diet,and the test diet were added 0.2g/kg Saccharin sodium(SS)?0.2g/kgPES?0.4g/kg PES separately.160 piglets with good body weight and similar body weight were selected,whose sows has the same genetic background and physiological status.These piglets were randomly divided into 4 groups,each group has 4 replicates,and in each replicate there are 10 piglets.The test lasted 35d.The control diet is the basal diet,which didn,t add any flavor agents.The piglets in test groups of A?B?C were feed with test diet,and the test diet were added 0.2g/kgSS?0.2g/kgPES?0.4g/kg PES separately.The experiment is divided into 2 parts:The first stage is lactation stage,those groups were trained with control diet and the test diets to teach groove.The second stage is from the age of 24 to the age of 42,it is the weaning transition stage.The results display that:1)The Fodder perference and partial eclipse indexes of group A?B?C were 52.20?56.04?56.54andl.09?1.28?1.30.2)The F/G of groupB and groupC on weaned piglets reduced extremely significantly in the weaning transition stage(P<0.05).The ADFI and ADG of groupB and groupC on weaned piglets incresed extremely significantly in the weaning transition(P<0.05).3)The NE?DAO and L-lactic acid level of weaned piglets with group Cwere reduced significantly(P<0.05).The COR level of weaned piglets with group B was reduced significantly(P<0.05).These results showed that there was a medium preference of group C and group B.The diets with group B and group C could improve the growth performance and relieve the EWS in different levels.Compared with all the various indicators,the best effect group was 0.4g/kgPES group.Trial two:Application effects of CF and PES on weaned piglets.The experiment has two parts.36 piglets,whose age were 24-days-old,were used in test(1).These piglets were randomly divided into 3 groups,each group has 4 replicates,and in each replicate there are 3 piglets.The test lasted 5d.The control diet is the basal diet,which didn,t add any flavor agents.The piglets in test groups of ?????were feed with test diet,and the test diet were added CF1g/kg+ 0.2g/kgSS.0.2g/kgPES+CF1g/kg?PES0.4g/kg+CFlg/kg separately.160 piglets with good body weight and similar body weight were selected,whose sows has the same genetic background and physiological status.These piglets were randomly divided into 4 groups,each group has 4 replicates,and in each replicate there are 10 piglets.The test lasted 5d.The control diet is the basal diet,which didn,t add any flavor agents.The piglets in test groups of ????? were feed with test diet,and the test diet were added CF1g/kg+0.2g/kgSS?0.2g/kgPES+CF1g/kg?PES0.4g/kg+CF1g/kg separately.The experiment is divided into 2 parts:The first stage is lactation stage,those groups were trained with control diet and the test diets to teach groove.The second stage is from the age of 24 to the age of 42,it is the weaning transition stage.The results displayed that:1)The Fodder perference and partial eclipse indexes of group ????? were 54.39?59.01?62.27and 1.20?1.44?1.66.The F/G of weaned piglets with group ????was reduced extremely significantly in the weaning transition stage(P<0.05).The ADFI and ADG of weaned piglets with group ????were incresed extremely significantly in the weaning transition(P<0.05).3)The Diarrhea rate of weaned piglets with group ? was reduced extremely significantly in the weaning transition stage(P<0.05).4)The CCK?NE?ADR?and L-lactic acid level of weaned piglets with group II were reduced significantly(P<0.05).The CCK?NE?and L-lactic acid level of weaned piglets withfroup I was reduced significantly(P<0.05).These results suggested that there was a medium preference of group ??group I.The diets added group ? and group I could improve the growth performance and relieve the EWS in different levels.Compared with all the various indicators,the best effect group was 0.4g/kgPES+FE group.Trial three:Application effects of FE?PES and their compound on weaned piglets.The experiment has two parts.48 piglets,whose age were 24-days-old,were used in test(1).These piglets were randomly divided into 4 groups,each group has 4 replicates,and in each replicate there are 3 piglets.The test lasted 5d.The piglets in test groups of 1?2?3?4were feed with test diet,and the test diet were added FE0.2g/kg?PES 0.2 g/kg?SS 0.2g/kgPES 0.2 g/kg +FE 0.2g/kg separately.2)200 piglets with good body weight and similar body weight were selected,whose sows has the same genetic background and physiological status.The experiment has two parts.These piglets were randomly divided into 5 groups,each group has 4 replicates,and in each replicate there are 10 piglets.The test lasted 5d.The piglets in test groups of 1?2?3?4were feed with test diet,and the test diet were added FE0.2g/kg?PES 0.2 g/kg?SS 0.2g/kgPES 0.2 g/kg +FE 0.2g/kg separately.The experiment is divided into 2 parts:The first stage is lactation stage,those groups were trained with control diet and the test diets to teach groove.The second stage is from the age of 24 to the age of 42,it is the weaning transition stage.Results showed that:1The Fodder perference and partial eclipse indexes of group 1?2?3.4were 51.97.56.97.61.43.55.60 and 1.08.1.33?1.60?1.25.2)The F/G and diarrhea rate of weaned piglets with PES+FE was reduced extremely significantly in the weaning transition stage(P<0.05).The ADFI and ADG of weaned piglets withPES+FE were incresed extremely significantly in the weaning transition(P<0.05).3)The COR.DAO and L-lactic acid level of weaned piglets with FE+PES and PES were reduced significantly(P<0.05).The Ghrelin level of weaned piglets with FE+PES and PES were increased significantly(P<0.05).The L-lactic acid level of weaned piglets with FE was reduced significantly(P<0.05).The Ghrelin level of weaned piglets with FE was increased significantly(P<0.05).There were some interaction with FE and PES in Ghrelin level of weaned piglets.These results suggested that there was a medium preference of FE+PES?PES and FE.The diets added PES+FE.PES and FE could improve the growth performance and relieve the EWS in different levels.Compared with all the various indicators,the best effect group was PES+FE group.Thus,it can be seen that the addition of different levels of PES,PES+CF?the feed of FE?PES?FE+PES can improve the performance of weaned piglets and alleviate the early stress of weaned piglets.The 0.4g/kgPES,CF+0.4g/kgPES,FE+ PES were recommended to add.
