A Strategy To Predict The Global Warming Gas From Stock Farming —Potential Scaling Law Of The Released Methane From Livestock—, Toshiaki Nakashima, Tsuneyoshi Matsuoka, Yuji Nakamura
Progress in Scale Modeling, an International Journal
This work examines a scaling approach to predict the amount of methane released from the daily activity of livestock on farms. The subject animals are ruminants, i.e. having rumen or a ruminant stomach, that generates methane through digestion processes via several microbial fermentation steps. The produced methane is mixed into their breathing and released into the atmosphere. Existing data on methane released from various kinds of ruminant livestock were correlated as a power function of an animal’s weight, with an exponent near 0.92. This value is larger than a value of 0.75 which was related to the general metabolism rates …
Cultivating The Next Generation Of Pasture Scientists In Australia, Sarita Jane Bennett
Cultivating The Next Generation Of Pasture Scientists In Australia, Sarita Jane Bennett
IGC Proceedings (1997-2023)
Current students coming through agricultural faculties in Australian universities have grown up in an era of low wool and meat prices, the introduction and acceptance of no-till farming as the norm and a general decrease in mixed farming landscapes in favour of continuous cropping. Since the collapse of the wool reserve price scheme in 1991, wool prices declined and income on wool producing farms followed suit. R & D during this period has also declined from 5-4% agricultural GDP in 1986 to only 3% in 2005 and has favoured research related to cropping rather than that related to pastures and …

Factors Affecting Rangeland Utilization By Ranchers In The Golestan Rangelands, Iran, Reza Tamartash, Mohammadreza Tatian, Maedeh Yousefian, Fatemeh Montazeri, Hamid Mostafalou
IGC Proceedings (1997-2023)
In Iran, rangelands produce most of the forage resources for livestock. There are various types of traditional grazing systems for the utilization of rangelands, including the consultative, collective and operational multiplayer systems. In the consultative type, certain people are selected by the ranchers and they determine the utilization method and manage grazing. In the collective system, all ranchers use rangeland in common. In the operational multiplayer system, rangelands are used in common but the ranchers share rangelands by rancher-rancher negotiation. This research was undertaken to investigate the human factors as rancher's effect on rangeland utilization in different systems above mentioned.

Ruminant livestock are essential to the livelihoods of smallholder farmers in many developing countries. Livestock production on these farms is characterised by low milk production, low live weight gain and poor reproductive performance because of poor nutrition. Access to high quality forage has been identified as key to improving livestock health and productivity. Conservation of surplus forage as hay or silage provides the opportunity to ensure livestock have access to high quality forage year-round. This paper reports on forage conservation in select countries in Asia and Africa.

Cactus (Opuntia ficus-indica (L) Mill) is spineless and offers several benefits to both man and livestock. It is a succulent, xerophytic, spiny or spineless plant of multiple uses (Felker et al., 1997). Cactus is a drought resilient feed, introducing cactus as alternate livestock feed in dryland ecosystems fulfill the deficiency of feed to livestock. Cactus requires little moisture which used to gets from the rainy season to produce large quantities of forage. It has a higher carrying capacity than any other drought tolerant fodder in arid and semi-arid areas. It remains green and succulent during drought thus …

Salt-Tolerant Forages For Irrigated Saline Land In Central Iraq, Iman S. Salman, Edward G. Barrett-Lennard, Kareem Kadhim, Shoaib Ismail, Hayley C. Norman
IGC Proceedings (1997-2023)
Salinity is a major problem in the irrigated zones of central and southern Iraq. We investigated biomass production from five salt-tolerant forage species, represented by 15 introduced accessions and 3 local accessions, during two successive summer growing seasons. Species included pearl millet (Pennisetum glaucum), sorghum (Sorghum bicolour), guar (Cluster bean; Cyamopsis tetragonoloba), cowpea (Vigna unguiculata) and sesbania (Sesbania aculeata and S. sesban). The research site was located in the Al-Dujaila irrigation project area in Wasit. The soil had a silty clay texture with moderate salinity (ECe 10-20 dS/m). The site was …

Mineral Status Of Livestock, Soil, Feeds And Fodders In Ajmer District Of Rajasthan, Sheela Choudhary, Ramkesh Meena, Sunil Dutt Choudhary, Poonam Yadav
IGC Proceedings (1997-2023)
A large number of Indian livestock suffer from deficiencies or imbalances in minerals because they are mainly maintained on crop residue based rations and grazing without access to mineral supplement (Mc Dowell et al., 1993). Deficiency or imbalance of single or multiple minerals results in enzymatic dysfunction and hormonal imbalance associated with fertility of animals (Maurice, 2003). In India where dietary concentration of fodder fed to the animals are unknown or highly variable due to availability, season, location, forage, species and animal potential (Sharma et al., 2003), it is important to determine plasma mineral concentrations in animal region wise, …

Strategies On Poisonous Plants Problem In China, Xinlei Gao, Mengli Zhao, Jing Wang, Bin Han, Walter D. Willms
IGC Proceedings (1997-2023)
Poisonous plants are widely distributed on large areas of native grasslands of China, causing livestock poisoning and grassland degradation, which severely impacts the development of animal husbandry. Of the almost 300 poisonous species that are responsible for livestock losses in China, locoweed, drunken horse grass and Langdu cause the greatest impact. Many strategies have been developed to minimise the impact of poisonous plants including the treatment of livestock that have been poisoned, controlling poisonous plants and managing livestock grazing. Both physical and chemical traditional methods are still used to eliminate poisonous plants while biological control using specific insects may eventually …

In Ladakh, livestock rearing is a major activity in the livelihoods of the population and contributes greatly to income generation in the region and therefore alleviating poverty. In agro-pastoral animal husbandry systems of Leh, Khaltsey, and Nubra blocks and limited areas in Nyoma and Durbok, villagers live in settled communities and practice sedentary agriculture, but they also keep relatively large herds of livestock to augment income and meet dietary and fibre subsistence needs (Ahmed, 2002). Due to prolonged and extreme cold winter, the agriculture season is very short which starts from May and ends by September depending upon different altitudes. …

Radiant Temperature Of Cattle According To Rangeland Environment And Breed, Luciano A. González, Anne-Sophie Clerc, Christopher J. O’Neill
IGC Proceedings (1997-2023)
Heat stress can reduce growth rate and reproduction of beef cattle in tropical regions, which might be accentuated under a scenario of climate change. Adaptation of breeds, acclimatisation of individuals, and shade (natural or artificial) can be used to mitigate heat stress in cattle with body temperature used as an indicator (Finch 1977). In the past few years, infrared temperature (IRT) of the eye and hide have been used as an indicators of core body temperature for disease detection and heat produced (Schaefer et al. 2012; Montanholi et al. 2008). IRT could become an automatic and remote measurement …
Estimated Effects Of Climate Change On Grassland Production And Legume Content Across Southern Australia, Andrew D. Moore, Afshin Ghahramani
Estimated Effects Of Climate Change On Grassland Production And Legume Content Across Southern Australia, Andrew D. Moore, Afshin Ghahramani
IGC Proceedings (1997-2023)
Climate changes caused by anthropogenic increases in greenhouse gases such as CO2 will affect southern Australia along with the rest of the globe. Dryland pastures supporting extensive beef, sheepmeat and wool production occupy a third of southern Australia’s farming zone. These livestock production systems are highly sensitive to climatic variation, because they depend almost entirely on pasture as their source of feed. Given the diversity of current climates, soils and pastures that are found across southern Australia, and the spatial variation in projected climate changes (CSIRO 2007), it can also be expected that the impacts of changing climates on …
Comparative Analysis Of Climate Change Adaptation Options Across The Southern Australian Livestock Industry, Afshin Ghahramani, Andrew D. Moore
Comparative Analysis Of Climate Change Adaptation Options Across The Southern Australian Livestock Industry, Afshin Ghahramani, Andrew D. Moore
IGC Proceedings (1997-2023)
Climate change is predicted to have a substantial negative effect on the productivity of grasslands across southern Australia (Moore and Ghahramani 2013). We used the GRAZPLAN biophysical simulation models to assess several possible grassland management and animal genetic improvement adaptations under SRES A2 climate change scenario. Simulations spanned the five dimensions of geography, time, global circulation models, enterprise, and adaptations. Impact of climate change was predicted to reduce profitability of livestock industry by 46%, 58%, and 72% at 2030, 2050 and 2070, respectively. Increasing soil fertility could return the average profitability of five livestock enterprises to its historical level at …
