Classification of bovine teat condition can be used to assess the effects of milking management, milking equipment or environment on teat tissue and the risk of new intramammary infections. Veterinarians and others require a simple and reliable method for evaluating teat health in dairy herds. A protocol for systematic evaluation of teat condition in commercial herds is proposed. Guidelines for...
this study was carried out to investigate the effects of integrative vs. instrumental motivation, learning strategy use and gender on iranian efl learners. to this end, 120 efl learners both male and female majoring in english language and literature at shiraz university participated in the study. in order to conduct this study three instruments were used: oxford quick placement test, motivatio...
The health and integrity of teats and streak canals is positively correlated to udder health and the incidence of mastitis. One sign of a reduction in teat end integrity is formation of excessive callus known as hyperkeratosis. Seiber and Farnsworth were the first to identify teat end hyperkeratosis and establish a teat end scoring system. Scoring systems have been developed to help standardize...
The Ribosomal Database Project (RDP) is a curated database that offers ribosome-related data, analysis services and associated computer programs. The offerings include phylogenetically ordered alignments of ribosomal RNA (rRNA) sequences, derived phylogenetic trees, rRNA secondary structure diagrams, and various software for handling, analyzing and displaying alignments and trees. The data are ...
: Friesian-type dairy cows were milked with different machine settings to determine the effect of these settings on teat tissue reaction and on milking characteristics. Three teat-cup liner designs were used with varying upper barrel dimensions (wide-bore WB = 31.6 mm; narrow-bore NB = 21.0 mm; narrow-bore NB1 = 25.0 mm). These liners were tested with alternate and simultaneous pulsation patter...
Preparing cows for milking is one of the most important operations. Not only speed milk production but also quality depends on level work performed.
 One effective ways to mechanize preparation implies development a special mechanical brush that cleans and stimulates teat skin. As result, there no need use additional foam detergents napkins cleanse disinfect teats.
 A device has been ...
The presence of mastitis in bred dairy heifers can adversely affect the development of milkproducing tissues, leading to less than maximal milk production and increased somatic cell counts (SCC) during their first lactation. Use of nonlactating cow therapy has been beneficial in curing existing intramammary infections (IMI), and teat sealants have been beneficial in preventing new IMI from deve...
if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
OBJECTIVE Three genome-wide association studies (GWAS) and a meta-analysis of GWAS were conducted to explore the genetic mechanisms underlying variation in pig teat number. METHODS We performed three GWAS and a meta-analysis for teat number on three pig populations, including a White Duroc×Erhualian F2 resource population (n = 1,743), a Chinese Erhualian pig population (n = 320) and a Chinese...
