Background: Species identification in commercially processed food and feed products is one of the important issues. This study was conducted to develop a genetic method for the detection of pig and cattle species in processed food and feed products using newly designed species-specific primers targeting mitochondrial 12S rRNA gene fragments. Methods: Two sets of specific primers were designed ...

Changes in performance traits in beef cattle over the last 30 yr necessitate the re-evaluation of central testing procedures to ensure that they are cost effective and appropriate for current test objectives. The objective of this study was to evaluate the potential for reducing the length of evaluation from 140 d to either 112 or 84 d. Data evaluated were postweaning feedlot performance test r...

This paper seeks to explore the potential phonological reasons for historical change of /k/ and /q/ in Najdi Arabic influence these two consonants on frequency duration vowels, such as /i/ sound through prism acoustic analysis. The phoneme transforms into [ts] [ɡ] [dz] many words. transformational process is called ‘palatalization’. Although it a universal phenomenon, palatalization has specifi...

Neospora caninum is a worldwide distributed pathogen which causes abortion in cattle leading to economic loss in the cattle industry. The aim of this study was to determine the seroprevalence of N. caninum antibodies in the native cattle slaughtered in various areas of Kurdistan province (western Iran) from September 2010 to September 2011. Serum samples from 368 cattle slaugh...

Abstract: In order to investigate the seroprevalence of Neospora caninum infection in cattle in Southwestern Iran, blood samples were collected from Holstein (121 animals) and cross-breed (436 animals) cattle from three farms and seven areas of Ahvaz, respectively. All of the Holstein cattle were “4 years old but cross-breed cattle were from different age groups ( < 2, 2-4, 5-6 and > 6 years ol...

one of the important aspects of the medicinal plants production is using less chemical inputs. it could be effective for increasing of production and environmental purposes. in order to investigate the effects of application time of integrated chemical fertilizer with cattle manure on growth, yield and yield components of black cumin (nigella sativa l.), an experiment was conducted based on a r...

A total of fifty multiparous ewes were selected immediately after lambing to study the relationship between udder morphology traits and milk production Najdi Naeimi (n=25/ breed) under intensive Saudi Arabia condition. Immediately lambing, lambs allowed suckle freely for 8 weeks; there weaned. During suckling period, typology, depth suspensory ligament in wear visually evaluated 3 weeks lambing...

milk urea nitrogen (mun) of dairy cows was determined in relation to breed. a total of forty (40) pabna and red chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. live weight of pabna cattle (187±14 kg) was higher than that of red chittagong cattle (174±4 kg). in pabna cattle milk yield (4.94 kg), minerals (0.15%) a...

As a beef cattle nutritionist, two things have been drilled into to me from early on: 1) the cheapest way to feed the cow is to let her “harvest” her own feed by grazing, and 2) corn is the cheapest source of energy for fed cattle. However, fluctuations in corn and land prices in more recent years have raised questions regarding the truth in these old adages. The objectives of these proceeding ...
