The effects of Meloxicam application on quality of life and development in calves

Although it is stated that there is an increase in calf loss rates at the global level and especially in modern dairy farms, this issue, which is an international animal welfare issue, has not been adequately defined at the national, large farm, or small farm level in most developing Countries. The rate of calf deaths before, during, and after birth is between 2–20% in heifers and cows. Previous studies showed that 75% of deaths occur during birth or within the first hour after birth, 10% before birth, and 15% within 48 hours after birth. This study aimed to determine the effect of Meloxicam administration on the quality of life and development of calves. An experimental method was used to achieve the aim of this research. A total of 60 Holstein calves, 30 in the experimental group and 30 in the control group, were included in the study for the study group. MELOXICAM (0.5 mg·kg-1) was administered to the mother cow and the calf immediately after birth, 2 days before the expected delivery. In this study, an 8 week process was passed to collect the data. It was concluded that Meloxicam did not affect the BHBA values of maternal cows. No calves died from pneumonia and diarrhea–related diseases after being treated with Meloxicam. From the total protein and total albumin values of the calves, it was concluded that Meloxicam did not affect the protein ratio, but did affect the albumin ratio. It was concluded that Meloxicam application increased the vital activity of calves

Mammary hyperplasia in a pregnant queen

Mammary hyperplasia producing severe swelling and ulceration of the mammary glands occurred during late gestation in a 10-month-old queen. Inguinal and caudal abdominal mammary glands and the left cranial abdominal mammary gland were asymmetrically and diffusely enlarged. Mammary gland skin was ulcerative and necrotic, and milk was leaking from the affected areas. To prevent mastitis the queen received topical antibacterial and anti-inflammatory drugs and systemic antibacterial and antiprolactin drugs. At the end of the first week following parturition, the majority of the mammary glands had regressed significantly with complete regression 14 days later

The Effect of Comfort- and Hot-Period on the Blood Flow of Corpus Luteum (CL) in Cows Treated by an OvSynch Protocol

The values of luteal blood flow (LBF), total corpus luteum (CL) area (TAR), and progesterone (P4), during and after OvSynch (OvS) protocol in comfort (CP; n = 40) and hot periods (HP; n = 40) were compared. We investigated how low and high P4 values obtained before the application affected the parameters above during CP and HP periods. Blood samples were collected before the OvS application on day 0 (OVSd0), day 9 (OeG), and day 18 (9th day after OeG: OvSd9). The P4 (ng/mL) values of the animals exhibiting dominant follicles were between 0.12–0.82 in HC and 0.1–0.88 in CP (P4-2: 4.36–4.38 and P4-3: ≥7.36 ng/mL). The LBF values were measured on days 7 (OvSd7) and 9 (OvSd9) after the OeG. The P4 mean values at day 0 (OvSd0) were classified as low (P4-1), medium (P4-2), and high (P4-3). The LBF and the TAR values in the P4-2 and P4-3 on OeG day 9 were higher than in HP (p < 0.05; 0.001), but there was no significant difference in the P4-1. In conclusion, when the OvS program was initiated with low P4 values, no difference was observed between HP and CP in terms of LBF values; however, when the program was started with high P4 values, there were significant increases in LBF and TAR values in the CP compared to the HP
