Predator control and sport hunting are often used to reduce predator populations and livestock depredations, but the efficacy of lethal control has rarely been tested. We assessed the effects of wolf mortality on reducing livestock depredations in Idaho, Montana and Wyoming from 1987-2012 using a 25 year time series. The number of livestock depredated, livestock populations, wolf population est...

As the basis of fine breeding management and animal husbandry insurance, individual recognition dairy cattle is an important issue in field. Due to limitations traditional method cow identification, such as being easy drop falsify, it can no longer meet needs modern intelligent pasture management. In recent years, with rise computer vision technology, deep learning has developed rapidly field f...

this research was conducted during 2009 at a regional scale in birjand and qaen counties, southern khorasan, as an attempt to develop a sustainability index (si) for quantifying the sustainability of saffron agroecosystem. the information of these agroecosystems, including socio-economic, agronomic and ecological indicators was collected using questionnaires and was subjected to statistical ana...

Livestock grazing affects over 60% of the world's agricultural lands and can influence rangeland ecosystem services and the quantity and quality of wildlife habitat, resulting in changes in biodiversity. Concomitantly, livestock grazing has the potential to be detrimental to some wildlife species while benefiting other rangeland organisms. Many imperiled grouse species require rangeland landsca...

The livestock sector’s potential for contributing to economic development and poverty reduction has so far remained largely untapped, and it is difficult to identify a single developing country where growth of the sector has been unambiguously pro-poor. Livestock have long been treated as an appendage to agriculture, with both policy-makers and development practitioners giving higher priority t...

This paper discusses the information needs of urban and peri-urban livestock keepers and the various information sources used and their effectiveness in disseminating livestock information. Mixed method approach was the methodology used in the study whereby quantitative data was gathered using questionnaires while qualitative data was gathered using in-depth interviews and participant observati...

Managing the environmental risk associated with livestock production is a significant challenge. Nitrogen and phosphorus are commonly implicated as the sources of ground and surface water quality problems associated with livestock production. The degree of imbalance between these nutrient inputs and the managed nutrient outputs for a livestock operation defines the magnitude of potential enviro...

Certain synthetic and naturally occurring chemicals, particularly those found in some range plants, may interact with livestock and poultry in the presence of activating light to produce photosensitization. Such photosensitization may have serious implications for livestock producers as a result of causing reduced performance of and even death of affected animals. The mechanisms producing photo...

Numerous factors affect livestock production and productivity. In this chapter we will address those that are of paramount importance: climate, nutrition, and health aspects. In initial section we will review the effects of climate on livestock productivity and provide examples of livestock adaptation to climate constraints such as the Bos indicus cattle breeds adapted to hot weather and the fa...
