The current study aimed to investigate if different sources of supplemental zinc (Zn), manganese (Mn), copper (Cu), and selenium (Se) fed to dry and lactating dairy cows affect reproductive performance, lameness status, and colostrum production. The experiment was carried out on 60 multiparous non-lactating Holstein cows in a commercial dairy herd. The cows(More)
The objective of this study was to estimate genetic parameters for growth traits and kleiber ratio in Moghani lambs. Traits included birth weight (BW), weaning weight (WW), 6-month weight (6MW), average daily gain from Birth to Weaning (ADG ), average daily gain from Weaning to 6 months of age (ADG ), 0-3 3-6 Kleiber ratio from Birth to Weaning (KR ) and(More)
The aim of present study was to determine the optimal period of fish oil inclusion in diet to access suitable n-3 fatty acids content in broiler meat. A total of 600 one-day old chicks were randomly allocated to six groups and reared for seven weeks. The control group fed a diet containing 5% corn oil and in the other five experimental groups, fish oil was(More)
This study was conducted in order to calculate the economic weights of milk yield and fat percent for the dairy buffalo production systems in the southwest of Iran. We collected herd structure, milk yield and fat percent records, revenues and costs data of 30 buffalo herds under the rural system in six cities for a 14-months period of calving interval.(More)
To determine the prevalence of Clostridium difficile in farm animals from slaughterhouse through to retail stage, a total of 750 samples of feces, posteviscerated and washed carcass were collected from cattle, camels, goats, and sheep in Isfahan, Iran. The overall prevalence of C. difficile in feces, posteviscerated and washed carcass were 20 (13.3%), 23(More)
BACKGROUND Clostridium difficile (C. difficile) is a frequent cause of nosocomial infections. During last few years, the mortality rate of C. difficile infection (CDI) increased in healthcare facilities. This organism has become a major public health concern in developed nations. Because of the increasing incidence of acquired-CDI (CA-CDI) and notable(More)
The recent increment of the incidence of Community Associated Clostridium difficile Infection (CA)-CDI has led to speculation that this disease is associated to foodborne transmission. Therefore it is critical to establish the community sources of CDI in order to implement the appropriate interventions. The present study was conducted to evaluate the(More)
The major pathogens causing mastitis were evaluated by multiplex-polymerase chain reaction (M-PCR) with self-designed primers in four quarters of the first, third, and fifth parities in industrial, semi-industrial, and traditional dairy cattle farms in Iran. With the incidence of infection in the quarters by Staphylococcus aureus and Streptococcus(More)
Yoghurt is a popular dairy product in Iran because of its beneficial influence on human health and nutritional value. Aflatoxin M1 (AFM1) is the metabolite of potential carcinogen aflatoxin B1, which can contaminate milk through the feed and is not eliminated by common processing heat treatment. An analytical method using immunoaffinity column for(More)
This study was conducted to investigate the effects of dietary betaine supplementation on de novo lipogenesis in liver of broiler. This study included 160 broilers (Ross 308) conducted in four treatments and four replicates. Each replicate consisted of 10 chicks in a completely randomized design. The diets consisted of the control treatment in which did not(More)
