Mastitis is one of the most serious and costly diseases affecting dairy cattle production. In the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (SCC) and subclinical mastitis was investigated in 121 Holstein dairy cattle. Two alleles of A and B and two genotypes of AA and AB were found in an EcoRI recognized single nucleotide polymorphism in int...

The objectives of this study were to determine 1) the effect of intramammary infection on calf weaning weight, milk somatic cell count, and milk composition, and 2) the effect of parity on percentages of infected cows, infected quarters, and blind quarters. The number of infected quarters, milk somatic cell counts, milk components, and intramammary infection were studied at weaning in 164 beef ...

Bulk tank somatic cell count (BTSCC) is a gold standard test for identification of milk quality, but its results are influenced by several interventional factors. Recently, application of acute phase proteins and especially milk amyloid A (MMA) has been considered as accurate parameters for milk quality study. The current research was done to evaluate the accuracy of MMA, BTSCC, fat, protein an...

The global production of sheep milk is growing, and the main industrial use cheese making. Spanish Churra breed one most important native dairy breeds in Spain. present study aimed to estimate genetic parameters for a wide range traits influencing cheese-making ability milk. Using total 1,049 ewes, we studied following traits: 4 related coagulation properties (rennet time, curd-firming curd fir...

Background and Aim: Mastitis in dairy cattle is associated with a high rate of morbidity death, which has major implications for milk production quality. This study aimed to investigate the protein component activity matrix metalloproteinase-2 (MMP-2) -9 (MMP-9) raw samples different testing scores determined using California mastitis test (CMT). Materials Methods: Thirty cows were employed stu...

108 milk samples were collected to study the relationship of somatic cell counts (SCC) and milk composition with milking methods and udder hygiene from 27 Holstein Frisian (HF) dairy cows having moderate milk yield in mid-lactation and parity of 2 to 4, at Khyber Pakhtunkhwa Agricultural University Peshawar dairy farm. All animals were randomly distributed into three categories on the basis of ...

Fluctuations in salinity impose stress on the physiology of the exposed fish population and can modify their structure. It has been noted that changes in blood characteristics and plasma levels serve as the primary link between environmental change and physiological response (McCormick, 2001). Ninety healthy adult Cyprinuscarpio (C. carpio) were randomly divided into five groups and kept in sal...
