Objective: Laminitis is one of the main causes of lameness in dairy cattle. In this situation the corium blood circulation is disrupted and the production of healthy horny hoof wall is reduced. The purpose of this study was to evaluate the arteriographic pattern of the digital arterial branches in the laminitic digits and to compare them with the normal digits. Design: Original study. Animals...

the importance of cats in the leptospira epidemiology is due to the possibility of transferring leptospirosis to wild and domesticated animals. the purpose of this survey was to determine the prevalence of leptospira infection in shorthair cats in different location of mashhad, iran. totally, 147 blood samples were taken from 42 (28.57%), 52 (35.37%) and 53 (36.05%) households, stray and cats w...

Background and Aims: Bovine leukaemia virus (BLV) is an oncogenic member of the genus Deltaretrovirus of the family Retroviridae. BLV is the causative agent of enzootic bovine leukaemia and infects cattle worldwide, imposing economic impact on the dairy cattle industry. The purpose of this study was to estimate the seroprevalence of BLV in cattle in some provinces of Iran. Materials and Methods...

Reducing chemical use for suppressing internal and external parasites of livestock is essential for protecting environmental health. Although plant condensed tannins are known to suppress gastro-intestinal parasites in small ruminants, no research on the effects of tannins on external arthropod populations such as the house fly, Musca domestica L., have been conducted. We examined the impact of...

Cattle manure is one of the primary larval developmental habitats of house flies, Musca domestica (L.). Cattle serve as asymptomatic reservoirs of Shiga toxin-producing Escherichia coli (STEC), and bacteria are released into the environment in cattle feces. The USDA-FSIS declared seven STEC serogroups (O157, O26, O45, O103, O145, O121, and O111) as adulterants in beef products. In addition, the...

BACKGROUND: Leptospirosis is a worldwide zoonosis causedby Leptospira interrogans. Leptospirosis results in decreasedmilk production, abortion, stillbirth, infertility and mortality,which causes financial loss in the cattle industry. OBJECTIVES:The aim of this research was to perform a serological andbacteriological study of leptospirosis in 6 industrial dairy herdsand 3 feedlots with previous ...

facultative heterofermentative lactobacilli (fhl) are responsible for enhancing unique flavour properties in traditional dairy products such as lighvan cheese through biochemical mechanisms. in addition to saving domestic genetic resources, industrial production of semi-traditional dairy products is one of the major objectives of non starter microflora identification in indigenous dairy product...

this research was conducted to study the nutrient balance condition of dairy cattle in semi industrial dairy farms of sought west of tehran province (eslamshahr) by the questionnaire techniques. the farms based on the herd were categorized in 6 group as follows: 1(1-30), 2(31-60).3(61-100), 4(100-130), 5(130-200) and 200 heads upward. the 30 farms have been selected randomly based on the random...

Genomic selection using high-density SNP panels was first implemented in dairy cattle breeding programs. It provided benefits in terms of reduced generation intervals, improved accuracies of selecting young animals, and reductions in costs associated with the requirement of progeny testing bulls in traditional breeding programs (Hayes et al., 2009). Several distinct features of the poultry bree...
