lactoferrin (lf) is a bioactive protein present in all external secretions such as milk that plays important role in the innate host defense. therefore, the lf has a major role in bovine mammary gland defense during mastitis. in this study, 5’-flanking region of bovine lf gene containing three single nucleotide polymorphisms (snps) at positions −602 (t/g), −600 (a/g) and -586 (t/c) were screene...

For all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. In the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by Psychrobacter sp. CSW4 was investigated by means of Taguchi approach and Box-Behnken statistical design under resting cell conditions. Taguchi desi...

Co-expression network analyses provide insights into the molecular interactions underlying complex traits and diseases. In this study, co-expression network analysis was performed to detect expression patterns (modules or clusters) of microRNAs (miRNAs) during lactation, and to identify miRNA regulatory mechanisms for milk yield and component traits (fat, protein, somatic cell count (SCC), lact...

background : since milk is considered as one of the most common foods in human life, this research aimed to evaluate the quality of milk produced in traditional and industrial dairy farms of yazd province in 2007.   materials and methods : in this descriptive study, six farms were selected in the cities sadoogh, yazd and mehriz and sampling was performed in each of them bimonthly throughout one...

Background: Erythrocytes require an ability to deform and to withstand shear stress while negotiating the microcirculation. These properties are largely due to their excess surface area per volume and the characteristics of the membrane’s protein. Deficiencies of these proteins are associated with chronic haemolysis. Methods: This was a cross sectional  study aimed at determining the prevalenc...

The effects of fat supplementation and weaning system on commercial milk yield and milk composition were determined on 129 East Friesian crossbred ewes. Prior to lambing, ewes were randomly assigned to one of two weaning systems. The DY1 system involved weaning of ewes from their lambs within 24 to 36 hr post-partum and then twice-daily machine milking. In the MIX system, ewes had access to the...

A 70-day feeding trial was performed to assess the effect of a mixture functional feed supplements (FFS; contains encapsulated cinnamaldehyde, condensed tannins, capsaicin, piperine, and curcumin) during mid-lactation on milk production composition, intake, blood profile multiparous dairy cows. Sixty Holstein cows (116.1 ± 17.1 days in milk, 606 9.3 kg BW, 45.73 6.7 kg/d production) were distri...
