Effects Of Varying Levels Of Protected Fat On Performance Of Shami Goats During Early And Mid Lactation, Hosam Titi
Effects Of Varying Levels Of Protected Fat On Performance Of Shami Goats During Early And Mid Lactation, Hosam Titi
Turkish Journal of Veterinary & Animal Sciences
This study was conducted to determine the responses of early lactating Shami goats to varying amounts of dietary supplementation of Ca salts of fatty acids. Shami goats (n = 75) in their first week of lactation were randomly assigned to 3 isonitrogenous dietary (TMR) treatments containing 0%, 3%, or 5% added Ca salt. The study took 60 days during which the following variables were measured: milk production and composition, body weight, feed intake, serum cholesterol and triglyceride, kids weaning weight, and milk fatty acids. Milk production and energy corrected milk were higher (P < 0.05) at 5% level. Percentages of milk composition were higher (P < 0.05) at 3% with CP% not different from 5%. No differences were observed in yields of different milk components including casein, final body weights, feed intake, or weaning weights of kids. Intake of metabolizable energy was higher (P < 0.05) at 5% level of Ca salts. Differences in milk fatty acids were mainly restricted to unsaturated ones with no effect on the saturated fatty acids. Such results suggest that milk production and content of lactating Shami goat can be changed by a level of 5% of Ca salts.

Acetic Acid Modulates Induction Of Pulmonary Hypertension In Broiler Chickens: Based On Electrocardiographic Parameters, Hossein Hassanpour, Abdolkarim Zamani Moghadam, Hamed Zarei, Neda Taghavi
Turkish Journal of Veterinary & Animal Sciences
To clarify the effect of acetic acid on the electrocardiographic parameters of pulmonary hypertensive broilers, chicks were reared at high altitude and treated with acetic acid (0.4 and 0.9 g/L) for 45 days. The right ventricle-to-total ventricle ratio was noted as an index of pulmonary hypertension that was significantly (P < 0.05) decreased in the treated groups. S amplitudes were significantly decreased only at 36 days (leads II and III) and 45 days (lead aVF) in many treated groups. There were significant (P < 0.05) reductions of T amplitudes at 28 days (leads aVR and aVL) and 36 days (lead aVL), and significant elevations of QRS (leads II, III, and aVF) and QT intervals (leads II, aVR, aVL, and aVF) at different ages of many treated groups. R amplitudes were significant (P < 0.05) at 28 days (leads aVL and aVF, at both doses of acetic acid), 36 days (leads aVR and aVL, at 0.4 g/L of acetic acid), and 45 days (lead aVR, at both doses of acetic acid). The RR interval also significantly increased at 28 days (leads aVR and aVL) and 45 days (lead aVL). It was concluded that acetic acid modulates induction of ventricular hypertrophy, dilation, and arrhythmia. These effects are detectable in many electrocardiographic parameters.

The Increase Of Cd4+Cd25+ T Cells In The Peripheral Blood Of Pigs Persistently Infected With Porcine Reproductive And Respiratory Syndrome Virus, Jingwen Zeng, Danting He, Xin Guo, Xinna Ge, Hanchun Yang
Turkish Journal of Veterinary & Animal Sciences
Regulatory T lymphocytes (T-regs) may be involved in suppressing the host's immunity, which is important for viral clearance, and may therefore contribute to persistent viral infection. However, nothing is known regarding the situation of porcine T-regs during persistent infection with porcine reproductive and respiratory syndrome virus (PRRSV). This study, which used flow cytometry and real-time PCR, determined that the frequencies of CD4+CD25+ T-cells and porcine Forkhead/winged helix transcription factor (FoxP3) mRNA levels in peripheral blood significantly increased during PRRSV persistence, indicating that CD4+CD25+ T-regs might play an important role in PRRSV persistent infection. This study contributes to a better understanding …

The \beta-mannosidase (MANB) enzyme is involved in removing mannose residue from the nonreducing end, and its impaired activity leads to \beta-mannosidosis. MANB amino acid sequences of humans, other mammals, plants, fungi, and bacteria were compared to determine their similarities, differences, and predicted 3D structures. Our cloned MANB DNA sequence showed a 99% similarity to a previously reported human MANB DNA sequence but 16 nucleotide differences were observed, showing the polymorphic nature of the enzyme. The 9 changed codons coded the different amino acids Ile, Lys, Ile, Thr, Arg, Leu, Leu, Gly, and Asp, while 7 changed codons coded the same …

The aim of this study was to establish the prevalence of repeat breeder syndrome (RBS) in different breeds and reproductive ages of cattle in central Croatia and to assess the effectiveness of hormone therapy as a treatment option. A total of 1088 dairy cows were observed, 218 heifers and 870 multiparous cows. After the third unsuccessful artificial insemination (n = 164) and a thorough clinical and gynecological examination, the cows were tested for sexually transmitted diseases. An RBS diagnosis was based on failure to conceive, negative laboratory tests for sexually transmitted diseases, and the absence of other reproductive disorders. The …
