Effects Of Dietary Fluoride Levels On Growth, Serum Indexes And Antioxidant Systems In Growing Pigs, Xin Tao, Zi Rong Xu, Yi Zhen Wang
Turkish Journal of Veterinary & Animal Sciences
Ninety-six growing pigs were used to evaluate the effects of fluoride levels on growth performance, serum indexes and antioxidant systems. Four dietary treatments were formulated by supplementing fluorine (as NaF) to provide the following added fluorine levels: 0, 50, 100 and 150 mg/kg. The results showed that pigs consuming diets with 100 and 150 mg/kg fluorine added had poor growth performance, and most serum biochemical indexes were significantly altered compared to the control (P < 0.05). On the other hand, serum and liver MDA concentration significantly increased due to the addition of 150 mg/kg fluorine (P < 0.05). T-AOC levels and the activities of SOD, GSH-PX, CAT and GST of serum and liver in fluoride added groups decreased, most of which altered significantly (P < 0.05). These results indicated that excessive fluoride ingestion had an adverse effect on animal health and performance.

Calving And Preweaning Growth Performance Traits Of Calves Sired By Charolais, Simmental And Eastern Anatolian Red Bulls, Abdülkadi̇r Özlütürk, Mete Yanar, Naci̇ Tüzemen, Si̇nan Kopuzlu
Turkish Journal of Veterinary & Animal Sciences
Charolais (C)-, Simmental (S)-, and Eastern Anatolian Red (EAR)-sired calves born in 2 locations in Eastern Anatolia were compared in terms of calving traits and preweaning growth characteristics. Breed of sire effects were significant (P < 0.01) for birth weight, 205-day weaning weight, average daily weight gain from birth to weaning, and some body measurements at birth. S- and C-sired calves were heavier at birth and larger for most body measurements at birth than EAR-sired calves. The C- and S-sired calves also had higher 205-day weight than the EAR-sired calves. Although the level of calving difficulty was higher in the S and C crosses, the differences were not statistically significant. Male calves had significantly (P < 0.01) heavier birth and 205-day weights, higher preweaning average daily gain and greater body measurements (e.g., height at withers, heart girth and cannon bone girth) than females. Location differences were also significant (P < 0.01) for survival rate from birth to weaning, preweaning growth rate and 205-day weight. In conclusion, although C- and S-sired calves performed similarly for most traits, all parameters of the preweaning growth were higher in calves sired by S and C bulls than in calves sired by EAR bulls. Therefore, both C and S could be considered as sire breeds for crossbreeding programs to be implemented in Eastern Anatolia, since these breeds did not cause an adverse influence on the calving and growth traits of the crossbred calves.

The detection of Listeria monocytogenes in Helix pomatia, both raw and cooked is presented here. Polymerase chain reaction (PCR) is a rapid procedure with both sensitivity and specificity for quick detection and identification of Listeria monocytogenes from raw and cooked Helix pomatia. A total of 30 bags (10 g each) of H. pomatia samples were investigated for the Listeria monocytogenes inlB gene with the PCR method. PCR amplification products demonstrated that 18 of the 30 samples showed positive reactions to Listeria monocytogenes in the PCR. All PCR positive samples showed specific amplification of the 343 bp fragment for Listeria monocytogenes.
