Economic Value Of Improving Feed Efficiency Of Beef Cows On Pasture, J. T. Biermacher, J. K. Rogers, D. Lalman, A. Holder, R. S. Walker
IGC Proceedings (1977-2023)
Dry matter intake of beef cows is based on a percentage of body weight, so as mature cow size increases, intake increases. Feed efficiency, or the amount of feed required to produce gain or maintain production, has a direct impact to the producer. That is, as mature cow weight increases, yearly maintenance costs increases due to higher feed costs. However, variation in feed efficiency exists within population. Some large cows consume the same or less dry matter as a smaller cow, but produce a larger calf. Conversly, some smaller cows consume the same or more as a large cow but …

IGC Proceedings (1977-2023)
There is evidence that effective shelter can significantly improve lamb survival, but the majority of Australian studies have occurred in small paddocks where the ewes had no choice but to use shelter. In mixed farming systems with large open paddocks, it is unclear if ewes will choose to use shelter for lambing. Our multidisciplinary collaboration examines the use of woody shrubs as an opportunity to improve the survival of twin lambs. In a series of large experiments on commercial farms, we will evaluate the impact of different shrub planting configurations, orientations, and densities on microclimates at the sub-paddock scale. Twin-bearing …

Environmental Co-Benefits Of Improved Forages In Smallholder Dairy Systems Of Kenya, A. Notenbaert, S. Mwendia, S. Burkart, P. Karimi, E. Mwema
IGC Proceedings (1977-2023)
Livestock play a major role across Kenya, especially in smallholder mixed farms through provision of household nutrition and income through milk and meat. Equally, fertilization of cropland benefits from livestock manure, and livestock often act as insurance and saving. Despite the opportunities and benefits livestock production presents, livestock systems are also key drivers of environmental degradation, including increased nutrient loads, GHG emissions, water use, grassland degradation and land-use conversion. Low livestock productivity, largely due to use of low-quality crop residues and natural grasses often not endowed with nutrients key for animal performance, limits the potential positive contributions of livestock and …

IGC Proceedings (1977-2023)
In a diverse pasture of complementary species (DPCS), individual species fulfil agro-ecological functions that confer growth asynchrony and complementarity of ecosystem functions. These attributes provide yield consistency with a more even forage supply pattern across the year compared to monocultures. A common leaf regrowth stage window opportunity (LSWO) for the diverse species enables pasture defoliation that stimulates growth and persistence. The study assessed seasonal and annual growth traits of Lolium perenne (Lp), Bromus valdivianus (Bv) and Dactylis glomerata (Dg) as single grass species (Mono) sown with Trifolium repens (Tr) and as DPCS with the four species (Lp+Bv+Dg+Tr=Mix). The defoliation criteria …
