This study was conducted at poultry farm of the College of Agriculture, University of Baghdad during the period from the 21st of July to 26th of August of 2001 toidentify the effects of vineger on broiler performance at the two weeks of breeding period during summer season. One hundred and twenty unsexed faw-bro broiler chicks divided randomly into two equal groups consisted of 60 chicks in each (3 replicate of 20 chicks each ) they were exposed to one of the following treatments:-- Treatment 1: tap water for the 7 and 8 weeks of age.- Treatment 2: water + vineger (0.1%) for the same period.The results showed that treat.2 enhanced significantly (P<0.05) body weight compared with treat.1 . The mean body weight were 1200 and 1150 gm at 7 weeks of age and 1500 , 1400 at 8 weeks of age respectively. Also adding 0.1% vineger to drinking water improved significantly (P<0.05) feed intake, feed conversion and decreased mortality at 7 and 8 weeks of age
The objective of this study was to determine the effect of dietary aspirin on performance, healthstatus of broilers reared in high density (15 birds / m 0) . Ninety chicks 7 days old were distributed intotwo treatments , chicks in T1 fed a diet without aspirin (control) , chicks in T2 fed a diet supplementedwith 0.2 % aspirin . Each treatment was subdivided into three replicates and each replicate reared in 1X 1 m pen. Live body weight, weight gain , feed consumption , feed conversion ratio and mortality dueto ascites biweekly were recorded , also activity of some blood enzymes included GOT , GPT and ALPat 7 weeks of age . The data obtained revealed the following :Adding 0.2 % of aspirin in diet (T2) enhanced performance of broiler chicks compaired with control(T1) when reared in high density and the enhancement started at week 5 , dietary aspirin increased livebody weight , weight gain , feed conversion ratio and decreased total mortality and mortality due toascites , also dietary aspirin decreased ascites syndrome through decrease of liver and heart weightpercentages and decrease the activity of GOT and GPT at 7 weeks of age . Adding 0.2 % of aspirin inbroiler diet are recommanded to reduce crowding stress and ascites syndrome during high densityproduction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
