Two feedlot studies were conducted with 96 Hereford steers to assess the relationship be:ween selenium adequacy and protein requirements of growing and finishing cattle. The first study was a 98-day growing trial with feeder steers as they gained from 230 to 340 kilograms. Diets contained 55% corn silage (dry matter basis) with shelled corn and were supplemented with soybean meal and sodium sel...

This study was conducted from September 2011 to May 2012 in Borana pastoral area with the objectives of determining the distribution and relative abundance of Ixodid ticks on cattle in relation to short rain and major dry seasons, cattle age and sex. A total of 8,912 adult ticks belonging to genera of Rhipicephalus, Amblyomma, Boophilus and Hyalomma were collected from 768 indigenous cattle. Rh...

The polled phenotype of cattle is increasingly becoming favourable mainly because of the enhanced emphasis on animal welfare, for which the causative mutations have been reported during the past years. The Shuxuan cattle are a new synthetic breed by crossing the indigenous cattle with both Simmental and Holstein semen in Sichuan of Southwest China, in which about 15% of polled individuals have ...

Wolf control to reduce cattle depredation is an important issue to ecology and agriculture in the United States. Two recent papers use the same dataset having wolf population characteristics and cattle depredation, but come to opposing conclusions concerning the link between wolf control and cattle depredation. Our paper aims to resolve this issue by using the same dataset and developing a mode...

Livestock has been the mainstay of Indian agriculture sector and also a major source of GHGs emissions from the world’s largest livestock population. The milching livestock (including lactating dairy cattle, buffalo and goat) constitutes 21.3% of the country’s livestock. We present a detailed inventory of GHGs emissions from milching livestock (using the recent census and country-specific emiss...

The myogenic determination 1 (MyoD1) gene is a member of the MyoD gene family. It encodes for skeletal muscle-specific transcription factors containing highly conserved basic helix-loop-helix regions that perform important roles in the initiation, maintenance, and regulation of phenotypic traits. We investigated a new single nucleotide polymorphism (SNP) in the MyoD1 gene to evaluate wheth...

In the following study, we analyze the usage of Twitter during four scientific conferences with focus on humanities and computer science. Automated analyses of tweets, retweets and @-messages were performed as well as an intellectual analysis of the tweets’ contents.
