“…Farmers sacrifice production in order to maintain other functions of cattle. Zemmelink et al (2003), Abegaz et al (2007), Budisatria et al, (2007) and Udo et al (2011) all argue that farmers optimise on the basis of maximal output of all functions combined and not on milk or meat production alone.…”

“…This was modelled for dairy production in a small (virtual) region with a total annual availability of 1000 tonnes of feed dry matter (DM) on the basis of information from studies by Zemmelink et al (2003) and Abegaz et al (2007). This availability of feeds determines livestock production.…”

“…With an increasing number of cows, more feed classes need to be included in the diet and the (mixed) diet's quality will decrease with decreasing individual animal production (Figure 1a), an increasing herd size maintained on the feed base ( Figure 1b) and a curvilinear relationship with total herd production (which equals herd size times production per animal; Figure 1c). Intake and dairy production were modelled for cows of 400 kg on the basis of studies by Ketelaars and Tolkamp (1992) and Zemmelink et al (2003). Figure 1c shows maximal herd output when up to class 4 feeds are being utilised.…”

“…Using a similar modelling approach, Zemmelink et al (2003) and Abegaz et al (2007) observed for regions in Indonesia and Ethiopia, respectively, herds with many more animals than the herd size for maximum production. If we, in the present example, assume that up to class 7 feeds are fed in order to maintain more animals to meet non-production functions such as manure production, traction and transport and capital store (all of which are favoured by a high number of animals) then 347 animals can be maintained with a total output of 875 kg of milk/day.…”

Because of an increasing demand for animal-source foods, an increasing desire to reduce poverty and an increasing need to reduce the environmental impact of livestock production, tropical farming systems with livestock must increase their productivity. An important share of the global human and livestock populations are found within smallholder mixed-crop-livestock systems, which should, therefore, contribute significantly towards this increase in livestock production. The present paper argues that increased livestock production in smallholder mixed-crop-livestock systems faces many constraints at the level of the farm and the value chain. The present paper aims to describe and explain the impact of increased production from the farm and farmers' perspective, in order to understand the constraints for increased livestock production. A framework is presented that links farming systems to livestock value chains. It is concluded that farming systems that pass from subsistence to commercial livestock production will: (1) shift from rural to urban markets; (2) become part of a different value chain (with lower prices, higher demands for product quality and increased competition from peri-urban producers and imports); and (3) have to face changes in within-farm mechanisms and crop-livestock relationships. A model study showed that feed limitation, which is common in tropical farming systems with livestock, implies that maximum herd output is achieved with small herd sizes, leaving low-quality feeds unutilised. Maximal herd output is not achieved at maximal individual animal output. Having more animals than required for optimal production -which is often the case as a larger herd size supports non-production functions of livestock, such as manure production, draught, traction and capital storage -goes at the expense of animal-source food output. Improving low-quality feeds by treatment allows keeping more animals while maintaining the same level of production. Ruminant methane emission per kg of milk produced is mainly determined by the level of milk production per cow. Part of the methane emissions, however, should be attributed to the non-production functions of ruminants. It was concluded that understanding the farm and farmers' perceptions of increased production helps with the understanding of productivity increase constraints and adds information to that reported in the literature at the level of technology, markets and institutions.

“…Feed availability is also dependent on the season and cropping pattern and the time of harvesting agricultural crops (Zemmelink et al 2003). Hence, the development of ruminant production at the farm level is positively related to the availability of feed resources and the socio-economic status of Table 3 Accessibility of feed and by-products to farmers during dry and wet seasons in Yogyakarta.…”

In tropical Indonesia, which has specific dry and wet seasons, it is difficult to provide high-quality forage in sufficient quantities throughout the year. Therefore, it is necessary to establish the availability and nutrient contents of forages and other natural feed resources during the dry and wet seasons in order to provide sufficient nutrients throughout the year, as an improvement effort the productivity of dairy cows. The method used was surveys conducted at dairy smallholder and groups selected in one of the areas of dairy cooperative in Yogyakarta; and observed environment condition (temperature and humidity). Feed samples were taken and analyzed in the Laboratory of Dairy Science and Milk Industry, Faculty of Animal Science UGM. Supplies of forages, agricultural by-products, feedstuffs, and commercial concentrates were available throughout the year, although the amounts were limited. Most of dairy smallholders had greater access to forages and agricultural by-products during wet season than during the dry season; this resulted directly in a better productivity of dairy cows during the wet season. In both seasons, farmers purchased commercial concentrates from other areas to support the cows feed requirements. Smallholder dairy farmers in the dairy areas of Yogyakarta had better access to forages and agricultural by-products during the wet season than during the dry season, but need to supplement their animals with commercial concentrates obtained from outside areas during both seasons. Assuring the continuity and availability of forages and concentrate in this area is of dire importance to reduce the dependency of feed from outside of the region.
