Hydrogen-rich water supplementation improves metabolic profile during peripartum period in Gurcu goats and enhances the health and survival of kids.

In this study, the effect of intaking hydrogen-rich water (HRW) on the metabolic profile of Gurcu goats during the peripartum period and the survival/growth performance of kids were evaluated. Twenty-three pregnant goats were divided into two groups 21-23 days before the due date. Group 1 (G1, n = 10) was given HRW from day 21 before delivery until day 21 after delivery. Group 2 (G2, n = 13) served as the control. Blood samples were weekly taken from 21 days before delivery until 21 days after delivery. Hydrogen-rich water increased serum glucose concentration on the delivery day more than in G2 (P = 0.016). Hydrogen-rich water decreased serum total cholesterol (P = 0.02) and creatinine (P = 0.05) concentration at delivery. Group effect and time effect were significant in triglyceride (P < 0.001, P = 0.001, respectively) and albumin (P < 0.001, P = 0.002, respectively) concentration. Aspartate transaminase decreased towards the delivery day in G1 (P < 0.05). Serum non-esterified fatty acids concentration was lower in G1 than in G2, but there was no significant differences (P > 0.05). Beta-hydroxybutyric acid concentration an increased in both groups during the prepartum period, although there was no significance (P > 0.05). Hydrogen-rich water did not affect the birth weight and growth performance of the kids (P > 0.05), but it increased their survival rates and overall health, although there was no significance (P > 0.05). In conclusion, HRW may have an impact on the metabolic profiles during the peripartum period and have a positive effect on lipid profiles. Additionally, intaking HRW to goats during the peripartum period may improve the health and survival of kids and reduce their mortality.

Zavot cattle genetic characterization using microsatellites.

This study aimed to reveal the genetic diversity and phylogenetic relationship between intra- and inter-breeds of Zavot cattle raised locally in and around Kars province, Türkiye. A total of 209 [Zavot (ZAV) n = 49, Eastern Anatolian Red (EAR) n = 40, Simmental (SIM) n = 40, Brown-Swiss (BS) n = 40, and Holstein (HOLS) n = 40] non-related cattle without any clinical health problems were evaluated. Using the standard phenol-chloroform method, deoxyribonucleic acid (DNA) was isolated from blood samples and amplified by multiplex polymerase chain reaction (PCR) using 19 bovine-specific microsatellite markers. A capillary electrophoresis process was applied to the denatured PCR products. A total of 274 different alleles were identified, with an average of 10.29 and an average of effective alleles of 5.38. According to the genetic distance matrix between populations, the largest genetic distance was found between ZAV-HOLS (0.358) populations, while ZAV-EAR populations were located at the same roots. The largest FST value (0.072) was found among ZAV-HOLS populations. According to the factorial correspondence analysis (FCA) graph, each population was located separately but also showed a mixture, especially the ZAV, EAR, and BS populations. The average polymorphism information content (PIC) values were the lowest (0.44) for the BM2113 marker and the highest (0.92) for the TGLA53 marker. In conclusion, ZAV cattle bred in the Kars region were found to be completely separate from the BS and SIM breeds which were claimed to have contributed to the formation of the ZAV breed. Since currently the native breeds, which are symbolic of the region, inbreeding cannot be prevented, an increase in studies devoted to the protection of these breeds and the establishment of pure herds will be useful for the future of native cattle in Türkiye.

Oestrus Synchronisation with Progesterone-containing Sponge and Equine Chorionic Gonadotropin in Pirlak Ewes During the Non-breeding Season: Can Toryum Improve Fertility Parameters?

INTRODUCTION: The aim of the study was to determine the effect of the vitamins, omega-3 polyunsaturated fatty acid and minerals in the supplement Toryum administered before and during oestrus synchronisation on some fertility parameters of ewes during the non-breeding season. MATERIAL AND METHODS: The experimental animals were clinically healthy Pirlak ewes, 55-75 days postpartum, aged 2-4 years and weighing 40-50 kg. A sponge was inserted into the vagina for 10 d (G1, n = 30; G2, n = 30) or 14 d (G3, n = 30; G4, n = 30) for oestrus synchronisation, and on the day of removal, 400 IU equine chorionic gonadotropin was injected. Toryum soft capsules were administered individually (1 capsule/ewe p.o.) to G1 and G3 ewes seven days before the sponge was inserted and on the day it was removed. Oestrus detection was started 12 h after sponge removal. Pregnancy was diagnosed by transrectal ultrasonography on the 30th day after mating. RESULTS: The pregnancy rate was statistically different between G1 and G4 (P < 0.05). The onset of oestrus was statistically different (P < 0.001) between the 10-d groups (G1 and G2) and the 14-d groups (G3 and G4). The litter size and oestrus, conception, lambing, multiple birth, and survival rates were not significantly different between the groups (P > 0.05). CONCLUSION: Toryum administered to Pirlak ewes during progesterone-based oestrus synchronisation protocols during the non-breeding season may increase pregnancy rates. The relationship between Toryum and fertility parameters in ewes would be better understood by comprehensive studies.
