Frequencies of polymorphisms at codons 136, 154 and 171 of the prion protein (PrP) gene were studied in 1207 pure-bred and cross-bred Italian Biellese rams, a small ovine breed of about 65 000 head in Italy. Aside from the five most common alleles (VRQ, ARQ, ARR, AHQ and ARH), the rare ARK allele was also found, with the highest frequency reported so far in an ovine breed (2.5 %). ARK/--- genot...

Aim: Uttarakhand is a relatively new state and many cross bred cattle were introduced to boost the milk yield of the state. Despite all efforts the milk yield of dairy in Uttarakhand is comparatively low. In our study, we assessed the effect of heat stress on milk production, using thermal humidity index (THI) in high (cross bred cattle) and low milk producing (LMP) cows (native cows) in Dehrad...
This document provides the problem statement and design space for 6LoWPAN routing. It defines the routing requirements for 6LoWPANs, considering the low-power and other particular characteristics of the devices and links. The purpose of this document is not to recommend specific solutions but to provide general, layer-agnostic guidelines about the design of 6LoWPAN routing that can lead to furt...
Cattle are a natural reservoir for Shiga toxigenic Escherichia coli (STEC), however, no data are available on the prevalence and their possible association with organic or conventional farming practices. We have therefore studied the prevalence of STEC and specifically O157:H7 in Swiss dairy cattle by collecting faeces from approximately 500 cows from 60 farms with organic production (OP) and 6...
The pharmacokinetics of cefpirome after a single intravenous injection of 10 mg.kg -1 was studied in febrile cross-bred calves. E. coli endotoxin was administered intravenously to induce fever in calves. Blood samples were collected at different time intervals and cefpirome levels were estimated by using microbiological assay technique. Based on the plasma drug levels, the pharmacokinetic pa...
Smallholder dairy production represents a promising income generating activity for poor farmers in the developing world. Because of the perishable nature of milk, marketing arrangements for collection, distribution and sale are important for enhanced livelihoods in the smallholder dairy sector. In this study we examined the relationship between market quality and basic feeding and breeding prac...
Effect of Different Feeding Times on the Performance of Cross Bred Dairy Cattle during Summer Stress
The livestock sector in Pakistan occupies a unique position in the national agenda of economic development. The current study was conducted to evaluate a heat stress mitigation strategy through different feeding times on the performance i.e. milk yield, milk composition and physiochemical properties of milk in dairy cattle during the summer season. Twenty Holstein Friesian cows (HF) were random...
