In this study, production, population and economic parameters of 30 buffalo herds of Khuzestan province in two sale conditions during 2016-2017 were used to estimate the economic value for production, reproductive and survival traits. Economic value of the traits were estimated by one unit increase for each trait using the maximum profit trend. The average annual revenue, cost and profit per he...
Background: Mastitis in sheep caused by Staphylococcus spp. is a serious concern for dairy farming. Aims: The objective of this study was to evaluate the impact of the intramammary infection (IMI) caused by Staphylococcus spp. on the long-chain fatty acid profile and composition of ewe’s milk. Methods: The experiment was conducted in a herd of Zoslachtena Valaska sheep. Half-udder milk samples ...
The aim of this work was to study the epidemiology and harmful effects of gastrointestinal nematodes (GINs) on dairy goats maintained in an intensive system. Two groups of goats were studied: untreated group (UG) (subdivided into UGjun goats that kidded in June, and UGjul goats that kidded in July) and treated group (TG) (with no subgroups, treated with monepantel: 3.75 mg/kg, orally, monthly)....

In selection index procedure, phenotype and genetic (co)variance matrices of traits are used for calculating different genetic parameters like index coefficients, index variance, genetic gain in selection goal and selection accuracy. Sometimes, it is possible that these matrices become inconsistent or they are not positive, nor definite. In the current study, for investigation of the effect of ...
Public Utility Commissions (PUC) in several states adopted 0.5 volt rms (root mean squared) or 1.0 milliampere as the actionable limit for utilities to respond to complaints of uncontrolled voltage. This study clearly shows that the actionable level should be reduced to 10 mV p-p (peak-to-peak), which is 140 times less than the current standard. Dairy farmer complaints that animal behavior and ...
The present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (DAP) in the mineral mixt...

Establishment and development of industrial husbandry in Kerman province have directed a great deal of provincial capitals toward this industry in recent years. Therefore, it is a must that efficiency of these production units is studied so that the situation of capital movement toward such units could be duly analyzed in the province. A helpful criterion to be employed is the analysis of produ...
Effect of Dietary and Animal Factors on Milk Fatty Acids Composition of Grazing Dairy Cows: A Review
In pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. Basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...
