the objective of this study was to determine the polymorphism of bovine β-lactoglobulin (β-lg) gene and its association with milk production traits in iranian najdi cattle. blood samples were collected from 80 najdi cattle from the najdi cattle breeding station located in shoshtar, khuzestan. polymerase chain reaction (pcr) and restriction fragment length polymorphism (rflp) techniqus were used...

To evaluate different levels of energy for optimum growth in Iranian regional buffalo male calves, a completely randomized study was conducted, using 27 yearling buffalo male calves with initial live weight of 201 ± 14 kg. Three diets were formulated to provide 90%, 100%, and 110% energy level requirements equivalent to those of steers derived from NRC beef cattle recommendations and they were ...

In Shahnameh and other epic poems, which reflect the myths, life of primitive ancient Iranian societies, animals are great importance go beyond their normal features status. Myths that truths thoughts ideas first people, mixed with different stories expressed symbolically cryptically. Epic events usually result linking these myths to history. Among animals, "cow" is one actors mentioned in Ferd...

many xenobiotic and natural compounds such as testosterone have been used and sometime misused to improve the growth of cattle and other livestock animals. in order to control the testosterone hormone residues in meat and to ensure the safety of iranian consumers, a monitoring system must be put in place to address the concerns. the present study was undertaken to detect and quantify the levels...

The objective of this study was to estimate the genetic parameters of milk protein yields in Iranian Holstein dairy cattle. A total of 1,112,082 test-day milk protein yield records of 167,269 first lactation Holstein cows, calved from 1990 to 2010, were analyzed. Estimates of the variance components, heritability, and genetic correlations for milk protein yields were obtained using a random reg...

BACKGROUND Fascioliasis, caused by Fasciola hepatica and F. gigantica, has medical and economic importance in the world. Molecular approaches comparing traditional methods using for identification and characterization of Fasciola spp. are precise and reliable. The aims of current study were molecular characterization of Fasciola spp. in West Azerbaijan Province, Iran and then comparative analys...

Background: The high polymorphism in the human leukocyte antigen (HLA) genes can be used as an identity of individuals to compare with other populations. This extreme polymorphism in the HLA system is accountable for the differences in alleles and haplotypes among ethnic groups, populations, and the inhabitants of many regions. Objective: To define the frequency of HLA alleles and haplotypes am...

The human calcium- and integrin-binding protein (CIB) family is composed of CIB1, CIB2, CIB3, and CIB4 proteins and the CIB4 gene affects fertility. Kermani sheep is one of the most important breeds of Iranian sheep breeds. The aim of this study was to analyze for the first time molecular characteristics of the CIB4 gene and protein in Kermani sheep. Different tissues were collected from the Ke...

BACKGROUND Despite improvements in child health, malnutrition still remains one of the main public health challenges in Iran. OBJECTIVES The aim of this study was to compare under nutrition among under-five children with regard to ethnicity in rural area in north Iran. PATIENTS AND METHODS In three cross-sectional studies 7575 subjects in three time-periods including 2339 children in 1998, ...
