Turkish Journal of Veterinary & Animal Sciences

This study was designed to determine carnitine concentrations in newborn calves with suspected septicaemia, healthy calves, and colostrum samples as well as to detect alterations in blood carnitine concentrations after colostrum intake. Carnitine concentrations were detected in both neonatal calves with suspected septicaemia (n = 195) and healthy calves (n =10) as well as in colostrum/milk samples from their dams (n = 20). The mean carnitine concentration on the 2nd day after colostrum intake (32.61 μmol/L) was significantly higher than that measured before colostrum intake (17.61 μmol/L) (P < 0.05). The striking result was significantly lower mean carnitine concentration detected in calves with suspected septicaemia (17.11 μmol/L), compared to healthy calves (24.92 μmol/L) (P < 0.001). Apart from a sudden increase on day 7, no significant alteration was observed in colostrum/milk carnitine concentrations throughout the postpartum period. The results indicated that colostrum contained carnitine, which passed into the bloodstream of the calf by passive colostral transfer, and that a dramatic reduction in blood carnitine concentrations of calves with suspected septicaemia existed. The results might be of help in dealing with septicaemia suspected neonatal calves through both measurement of blood carnitine and, in response, to supplement such cases with carnitine.

Turkish Journal of Veterinary & Animal Sciences

It was aimed to monitor postpartum (pp) uterine involution and follicular wave pattern by transrectal ultrasonography and detection of concentrations of milk progesterone (P4) in eleven water buffaloes during the summer season in Turkey. The data obtained from the first day of calving to positive pregnancy diagnosis were evaluated on a daily basis. Uterine position scores and nonechogenic material showed a decreasing grade pattern related to the time (P < 0.0001). A time effect was evident with uterine horn thickness (P < 0.05) or intercaruncular zone thickness (P < 0.01) and uterine horn lumen (P < 0.01). Uterine horn thickness showed a gravidity x time interaction (P < 0.05). Gravidity x time interaction was not evident in total uterine horn thickness but time effect was seen (P < 0.0001). Time effect was also evident for the thickness of uterine body (P < 0.0001) and cervix uteri (P < 0.01). The uterine body and horns were returned to previously nongravid state on day 26.00 ± 2.38 and the interval from calving to complete disappearance of uterine fluid was accomplished on day 31.44 ± 3.23 pp. The previously gravid and nongravid uterine horns, uterine body and cervix uteri involuted on day 31.42 ± 1.39, 28.37 ± 0.65, 29.37 ± 0.73 and 27.87 ± 0.47 pp, respectively. The interval from calving to first observation of dominant follicle of nonovulatory wave was 18.54 ± 6.91 days and on average 3.45 ± 1.91 nonovulatory waves were observed. Postpartum first ovulation occurred on day 64.45 ± 18.49. One and two wave models or combination of both waves were observed. The interval from calving to pregnancy was 72.36 ± 21.33 days. The maximum concentrations of milk P$_{4}$ during short or normal cycles and pregnancy were 0.62 ng/mL, 2.2 ng/mL, and 4.04 ng/mL, respectively. In conclusion, the presence of one or two waves should be considered when estrous synchronization programmes are planned in Anatolian water buffaloes during summer season.

Turkish Journal of Veterinary & Animal Sciences

This research examined the effects of liquid feeds on calf performance, rumen development, rumen cellulolytic bacteria count, and total bacteria diversity. Twenty Holstein bull calves were allocated to 2 groups either fed with milk replacer (MR) or whole milk. Calves fed milk tended to have higher (P = 0.058) average daily weight gain as compared to calves fed with MR during the entire experimental period. Starter mixture intake was not influenced by either milk or milk replacer feeding. Calves fed with milk had higher (P < 0.001) proliferative cells in the rumen papilla. The expressions of MCT1, MCT4, NHE1, NHE3, ACSS1, AceCS2, and ACSM1 genes, which are related to volatile fatty acid absorption, in the dorsal sac of the rumen were similar for calves fed either MR or whole milk. Fibrobacter succinogenes (P = 0.017) and Ruminococcus flavefaciens (P = 0.037) were significantly higher in the rumen of the milkfed calves. Moreover, denaturing gradient gel electrophoresis (DGGE)-derived dendrograms showed noticeable differences in ruminal microbial population between MR-fed and milk-fed calves. In conclusion, feeding calves with whole milk, which contains better quality protein and nutrients, instead of milk replacers, positively affects rumen development, cellulolytic bacteria numbers and total bacteria diversity.

The Morphological And Morphometric Characteristics Of Alabadem Pigeons, Evren Erdem, Fatma Tüli̇n Özbaşer, Eser Kemal Gürcan, Mehmet İhsan Soysal Jan 2021

The Morphological And Morphometric Characteristics Of Alabadem Pigeons, Evren Erdem, Fatma Tüli̇n Özbaşer, Eser Kemal Gürcan, Mehmet İhsan Soysal

Turkish Journal of Veterinary & Animal Sciences

This study aimed to determine the morphological and morphometric characteristics of Alabadem pigeons, which are grown as ornamental pigeons in Edirne province, and to determine mutual traits with other indigenous pigeon breeds in Turkey by comparing with previous studies. Body weight (P < 0.001), head length (P < 0.01), head width (P < 0.05), beak length (P < 0.001), and tarsus diameter (P < 0.05) of age group III were higher than those of other age groups; however, the wingspan of age group II was greater than that of other age groups in Alabadem pigeon. Compared to other indigenous genotypes in Turkey, the Alabadem pigeon is a small-sized genotype. Alabadem pigeons were similar to Edremit butterfly pigeons and Thracian tumbler pigeons in terms of crested and blackeyed pigeons. On the other hand, the irregularly shaped mark (almond) on the head in Alabadem pigeons was similar to the wide-long irregular shaped mark on the neck of Edremit butterfly pigeons. Some basic plumage colors (black, yellow, and red) and intermediate colors (chickpea and scarlet) were identical to Alabadem pigeons and Thrace roller pigeons. Since Alabadem pigeons have many mutual characteristics with Edremit butterfly pigeons and Thracian roller pigeons, genetic studies may be recommended to determine the degree of relationship among these breeds.

The mixed ligand coordination compounds containing acesulfamato and N,N-diethylnicotinamide biomolecules of some rare earth metal cations (Eu3+, Tb3+, Ho3+, Er3+ and Yb3+) were synthesized, and their structural properties were investigated. Possible structural formulas have been proposed by determining the chemical composition of molecules (elemental analysis), binding properties (infrared spectroscopy, mass analysis, solid-state UV-vis spectroscopy), thermal degradation properties (TGA / DTA curves). Based on the data collected, it is suggested that rare earth metal cations with a 3+ oxidation state have sextet coordination. The geometries of the structures were thought to be distorted octahedral. The charge balance of the coordination sphere …
