Turkish Journal of Veterinary & Animal Sciences

The study was conducted to determine growth, slaughter, and carcass characteristics of Lindovskaya geese. While a total of 237 goslings, 101 males, and 136 females were used to determine their growth characteristics, 16 male geese in total were used for the detection of the slaughter and carcass characteristics. Each slaughter group (12 weeks and 16 weeks old) consisted of 8 male geese. It was determined that the effect of sex on body weight values by week was significant (P < 0.05). In addition to this, the body weights of male geese were higher than the body weights of the female geese in all weeks. In the study, it was determined that the effect of the slaughter age on the weights of slaughter, head, blood, intestinal fat, and abdominal fat was significant (P < 0.05). Additionally, the values of the geese slaughtered at 16 weeks were higher compared to the geese slaughtered at 12 weeks. It was detected that the effect of slaughter age on the weight of the hot carcass, cold carcass, neck, breast and back, and other parts were significant (P < 0.05). Moreover, it was concluded that these values increased as the slaughter age increased. As a result, it can be said that slaughter age at 16 weeks was more preferable than at 12 weeks under breeder conditions. Additionally, it has been revealed that Lindovskaya geese need to be reared under controlled conditions, with regular care and feeding, to obtain better results.

Turkish Journal of Veterinary & Animal Sciences

In this study, African catfish (Clarias gariepinus) was investigated under controlled conditions in recirculating aquaculture system (RAS). The experiment tested the effects of three different dietary prebiotics (FOS: fructooligosaccharide, GOS: galactooligosaccharide, and MOS: mannanoligosaccharide) in two levels (1 g/kg and 2 g/kg) and a control diet on the growth performance, survival rate, haematological and biochemical parameters, and small intestinal and liver histology of the African catfish. Better growth results were obtained in MOS (2 g/kg) supplementation, and there was a statistical difference (P < 0.05) between the MOS (2 g/kg) and the control group. Haematological parameters (erythrocyte sedimentation rate, red blood cell, white blood cell, lymphocyte, neutrophil, and glucose) were similar among all groups (P > 0.05) while some (alanine aminotransferase, aspartate aminotransferase enzymes, and monocyte) were significantly different (P < 0.05). The MOS (2 g/kg) group had longer villi length values than the control group. There was no difference among the groups in terms of small intestine histomorphology and liver tissues in fish. According to the results of this experiment, it can be said that MOS addition has a positive effect on growth parameters and could improve health conditions in Clarias gariepinus culture.
