The effect of ovulatory follicle size at the time of insemination on pregnancy rate in lactating dairy cows

Abdulkadir KESKİN

The aims of this study were to determine the factors that affect follicle size at the time of artificial insemination (AI) and to detect the relationship between ovulatory follicle size at the time of AI and pregnancy rate in dairy cows. A total of 1428 follicle size measurements were obtained from Holstein-Friesian (HF) and Swedish Red (SR) cows that were inseminated with the fixed-timed AI protocols used in this study. Follicle size was affected by breed (P - 0.0001), milk production (P - 0.01), parity (P - 0.05), and season (P = 0.04). Follicle size was greater (P = 0.0001) in the HF (15.55 ...Более

The effects of varying levels of dietary starch on reproductivetraits in lactating dairy cows

Abdulkadir KESKİN

The aim of this study was to determine the effects of three different dietary starch levels on postpartum milk yield, blood metabolites, and reproductive traits in cows. A total of 23 primiparous Holstein-Friesian cows were fed three different diets including different starch levels on a dry matter basis from parturition until day 80. Cows were randomly assigned into the three groups according to the starch levels: low (LS, 16%, n = 7), medium (MS, 20%, n = 8), and high (HS, 24%, n = 8). Milk yields were recorded daily, and body condition score (BCS) was determined every week. Transrectal ultr ...Более

Is level of trace minerals important for healthy hoof in dairy cows?

Murat KİBAR

The aim of this study was to investigate the some trace mineral values on hoof in cows with hoof disease and comparison with healthy ones. Twenty-three Holstein dairy cows (hoof disease group (HD, 18 cases); control group (C, 5 cases) were studied. Determinations of Pb, Fe, Ni, Zn, Cd, Cu and Mn in the samples were carried out by inductively coupled plasma optical emission spectroscopy. Lead, Fe, Ni, Cd, Cu and Mn values were higher in group HD than group C, but just Pb, Ni, Cd, and Cu values were statistically significant. Zn value was lower significantly in group HD than group C. Sole ulcer ...Более

Effect of Hoof Trimming on Milk Yield in Dairy Cows with Foot Disease

Murat KİBAR

Backround: Milk is produced at the cost of other metabolic processes in the body and high milk yield has been associated with lameness and claw lesions. Lameness has also been associated with a decrease in milk yield. In the past, claw disorders and lameness in dairy cattle have been an increasing problem of the modern dairy industry. Hoof trimming is performed to prevent hoof lesions and improve gait by correction and maintenance of the hoof symmetry and shape. Lameness caused by hoof disorders can be treated by correct hoof trimming. The aim of this study was to test the hypothesis that one- ...Более
