A study was conducted for six weeks period to evaluate the effect of meat byproduct Sinews on commercial broiler performance in a total of 270 unsexed Vencobb chicks. The experimental feeds were prepared by including sinews at zero per cent (controlT1), 2 per cent (T2) and 4 per cent (T3) level in the feed. Addition of two per cent inclusion of Sinews in broiler chicken diet did not showed sign...
Growth and reproductive biology of Capoeta damascina (Valenciennes, 1842) from a tributary of Tigris
Growth and reproductive attributes were determined for Capoeta damascina, an endemic fish species from west of Iran. A total of 147 specimens of both sexes were sampled monthly from November 2008 to October 2009. The overall sex ratio was female biased. Males were aged 0-4 years and females 0-5 years. The von Bertalanffy growth parameters were estimated as Linf=34.81 cm, k=0.27 year-1, t0=-0.65...
The effects of enriching broiler chicken diets with a vegetable source of n-3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the accumulation of n-3 long chain polyunsaturated fatty acids (LCPUFA) in chicken meat were investigated. Sixty unsexed one-day-old broiler chickens (Cobb 500) were randomly allocated to one of six diets (n=10 birds/diet) for 4 weeks. The ALA levels varied fro...

This paper presents some biological features of juvenile and adult specimens of Atlantic bonito, Sarda sarda (Bloch, 1793), in the eastern middle Adriatic Sea. A total of 194 specimens were analysed, of which 93 were juveniles and 101 were adults. Juvenile individuals ranged from 5.7 to 8.4 cm while adults ranged from 39.3 to 56.7 cm. In order to analyse biometry, nine morphometric characters w...
The present study aimed to describe a simple technique for enema administration in one-day-old broiler chicks. For this purpose we used 455 unsexed health birds divided into four groups submitted to three different experimental protocols: in the first one, we measured the total length of the large intestine in order to establish a secure distance for probe introduction; in the second, we evalua...
