Prevalencija crijevnih helminata u tovnih pilića u Trinidadu.

A study was conducted between September 2009 and August 2010 to identify intestinal helminths in commercial broiler chickens and estimate their prevalencet in Trinidad. Three hundred and forty four intact intestines of commercial broiler chickens were obtained from eight counties and examined. Of these 36 (10.5%) were found to harbor helminths. The chickens were found to have a single infection with nematodes (5.5%), a single infection with cestodes (4.1%) and a mixed infection with nematodes and cestodes (0.9%). No intestinal trematodes were detected. Four species of nematodes were identified as Ascaridia galli (5.8%), Heterakis gallinarum (0.9%), Subulura brumpti (0.3%), Capillaria sp. (0.3%), and the three species of cestodes found were Raillietina echinobothrida (2.3%), R. cesticillus (0.9%) and Choanotaenia infundibulum (2.3%). Helminth infection was found to be highest in the county of St. George (34.9%) followed by St. Andrew (14%), Caroni (9.3%), Victoria (9.3%), Mayaro (9.3%), Nariva (2.3%), St. Patrick (2.3%) and St. David (2.3%). A significant (P<0.001) difference was found in the prevalence of helminth infection between the counties. In spite of the short life span and rearing under intensive farm management, broiler chickens in Trinidad harbor several intestinal helminths.Provedeno je istraživanje radi identifikacije helminata tovnih pilića i određivanja njihove prevalencije u Trinidadu u razdoblju od rujna 2009. do kolovoza 2010. U sklopu istraživanja bila su pretražena 344 uzorka crijeva pilića podrijetlom iz osam pokrajina u Trinidadu. Helminti su pronađeni u ukupno 36 uzoraka crijeva (10,5%). U 5,5% pretraženih uzoraka bila je ustanovljena jedna vrsta nematoda, u 4,1% uzoraka jedna vrsta cestoda, dok je miješana invazija dokazana u 0,9% pretraženih uzoraka. Ni u jednom pretraženom uzorku crijeva nisu pronađeni metilji. Identifi cirane su četiri vrste nematoda i to Ascaridia galli (5,8%), Heterakis gallinarum (0,9%), Subulura brumpti (0,3%), Capillaria sp. (0,3%) te tri vrste trakavica Raillietina echinobothrida (2,3%), R. cesticillus (0,9%) i Choanotaenia infundibulum (2,3%). Najveća prevalencija bila je dokazana u pokrajini St. George (34,9%). Manja prevalencija dokazana je u pokrajinama Caroni (9,3%), Victoria (9,3%), Mayaro (9,3%), Nariva (2,3%), Sv. Patrick (2,3%) i Sv. David (2.3%). Značajna razlika (P<0,001) bila je dokazana u prevalenciji helminata u pilića iz različitih pokrajina. Može se zaključiti da neovisno o kratkom životnom vijeku i uvjetima intenzivnog uzgoja, proizvodnju tovnih pilića u Trinidadu ugrožavaju helminti
