Group Feeding For The Lactating Cow, Anthony Joseph Martin
Group Feeding For The Lactating Cow, Anthony Joseph Martin
Dairy Science
Feeding individualized rations for lactating dairy cattle in the commercial herd based on dietary needs is a popular issue. This has been a debating topic since evolution of the Total Mixed Ration (TMR). Since dairymen were able to mix grain in a feed wagon and mix a specific dietary ration to meet the demand for an organized group, there has been an issue in which protocol cow pen grouping should take. Dairymen have always feed cattle based on if lactating or late in their gestation, nonlactating. With the evolution of the TMR dairymen are then allowed to go into more …

Production Losses Due To Endemic Foot-And-Mouth Disease In Cattle In Turkey, Berri̇n Şentürk, Cengi̇z Yalçin
Production Losses Due To Endemic Foot-And-Mouth Disease In Cattle In Turkey, Berri̇n Şentürk, Cengi̇z Yalçin
Turkish Journal of Veterinary & Animal Sciences
This research paper is aimed at estimating foot-and-mouth disease (FMD)-induced production losses in individual dairy and fattening cattle in Turkey. The data used were obtained from a Delphi Expert Opinion Survey. The weighted average FMD-induced financial losses for all breeds were estimated to be $294/head for a milking cow, $152/head for a dairy heifer and $197/head for beef cattle. However, the amount of financial loss varied across different breeds, ages, and sexes. The study findings suggest that culling Holstein breed cows, beef cattle, and Holstein and cross breed female calves, as soon as they have an FMD infection, would be …

Isotype-Specific Antibody Responses Against Escherichia Coli O157:H7 Locus Of Enterocyte Effacement Proteins In Adult Beef Cattle Following Experimental Infection, G. Bretschneider, E. M. Berberov, Rodney A. Moxley
School of Veterinary and Biomedical Sciences: Faculty Publications
Escherichia coli O157:H7 is an important food-borne pathogen and cause of hemorrhagic colitis and hemolytic uremic syndrome in humans. Cattle are an important reservoir of E. coli O157:H7, in which the organism colonizes the intestinal tract and is shed in the feces. Vaccination of cattle has significant potential as a pre-harvest intervention strategy for E. coli O157:H7; however, basic information about the bovine immune responses to important bacterial colonization factors resulting from infection has not been reported. The serum and fecal IgG and IgA antibody responses of adult cattle to E. coli O157:H7 intimin, translocated intimin receptor (Tir), E. coli …

Turkish Journal of Veterinary & Animal Sciences
Coxiellosis is a zoonosis caused by Coxiella burnetii. This study conducted to determine the prevalence of coxiellosis in cattle and farmers in Eastern Turkey. A total of 230 cattle and 92 human sera were collected and tested for antibodies against C. burnetii by a commercial ELISA kit. The antibodies to C. burnetii were detected in 22 (9.56%) cattle and 18 (19.5%) healthy farmers. Seropositivity was found in 12 of 53 (22.6%) cattle with an abortion history, and 10 of 177 (5.6%) cattle without an abortion history (P < 0.05). There was a correlation between animal and human seroprevalence in the same district. It was observed that the seroprevalence of coxiellosis was higher in northern districts (32.4% in farmers and 15.4% in cattle) than in other districts (12.1% in farmers and 6.5% in cattle) both for humans and animals (P < 0.05). Coxiellosis was an important health problem in both humans and cattle, and the disease may cause abortion in cattle in Eastern Turkey.

Use Of Indirect Excretory/Secretory Enzyme-Linked Immunosorbent Assay (Es-Elisa) For The Diagnosis Of Natural Fasciola Hepatica Infection In Eosinophilic And Non-Eosinophilic Cattle From Eastern Turkey, Sami̇ Şi̇mşek, Ergün Köroğlu, Armağan Erdem Ütük, Kürşat Altay
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to investigate fasciolosis in a group of eosinophilic and non-eosinophilic cattle in eastern Turkey. All the cattle were examined for antibodies against F. hepatica by modified indirect excretory/secretory enzyme-linked immunosorbent assay (ES-ELISA). Of the 1200 cattle tested, 164 (13.6%) were found to be eosinophilic by absolute eosinophil counts. Out of the 164 eosinophilic cattle, 121 (73.7%) were found to be positive for fasciolosis by indirect ES-ELISA, while the rate was only 35% among the non-eosinophilic group (P < 0.001). Our data indicate that parasitic infections should be considered an important cause of eosinophilia, particularly in fasciolosis, and the indirect ES-ELISA is useful as a screening test to examine anti-F. hepatica antibodies for the diagnosis of fasciolosis in cattle.

The prevalence of Cryptosporidium spp. and Giardia spp. in healthy asymptomatic cows and calves was investigated on 30 farms in Şarkışla in Sivas. The population on these farms consisted of 457 animals: 47 calves 15-45 days old, 48 calves 45-90 days old, 38 calves 90 days-6 months old, 254 calves 6 months-1 year old, 60 cattle 1-3 years old, and 10 cattle 9-15 years old. Cryptosporidium spp. oocysts were identified by zinc sulphate flotation technique and modified acid fast stain methods in cattle ranging from 15 days old to adults. Cryptosporidium spp. positive animals were found at all (100%) farms. …

The aim of this study was to investigate environmental factors affecting milk yield and fertility traits of Simmental cows raised at the Kazova state farm and the phenotypic correlation between these traits from 1473 records between 1992 and 2001. The least square means of 305-days milk yield, lactation duration, dry period, service period, calving interval, gestation length and number of inseminations per conception (NIPC) were 4700 kg, 300 days, 81 days, 94 days, 379 days, 283.6 days and 1.76, respectively. The effect of calving year on milk yield and fertility traits was statistically significant (P < 0.001). The effect of calving age on gestation length and milk yield was also statistically significant (P < 0.001-P < 0.05). The effect of calving season on gestation length, 305-days milk yield and NIPC was also statistically significant (P < 0.001-P < 0.05). Birth type did not significantly affect any traits, except for gestation length. The phenotypic correlations between 305-days milk yield and lactation duration (0.39), between NIPC and service period (0.81), between NIPC and calving interval (0.77), between calving interval and service period (0.96) and between calving interval and gestation length (0.12) were statistically significant (P < 0.001). Correlations between milk yield and fertility traits (0.09-0.77) were statistically significant (P < 0.001-P < 0.05), except for gestation length. These results are acceptable and it can be concluded that Simmental cattle are raised successfully on this farm and under Turkish conditions.

South Anatolian Red (SAR) cattle are well adapted to the arid, hot and harsh conditions of the region and have the highest milk yield among the local breeds in Turkey. The purpose of this study was to determine the main productive characteristics, such as viability, reproduction and milk production, of F_1, B_1 and F_{1}XB_{1} crossbred genotype groups from Simmental x SAR crossbreeding. A t test was used for 2 group comparisons. In cases of insufficient numbers of variants in the groups Kruskal-Wallis and Mann-Whitney U tests were used where appropriate. There was no difficulty during birth in any of the …
