Food production from livestock in small farm systems for urban populations in South East Asia por Devendra, C.

“…The South East Asian region has a diversity of ruminant and non-ruminant animals approximating to between 2-11 percent and 10-25 percent respectively of the total animal resources in Asia. Over the period 1981-1993, the annual rate of growth of the buffalo population was on the decline, however, cattle grew at 2.8 percent, and small ruminant -3.7 percent per year. …”

Bovine colostral cells : the often forgotten component of colostrum por Gonzalez, Diego, Dus Santos, Maria Jose

“…The acquisition of passive immunity, generally through the ingestion of colostrum, helps protect calves against disease during this critical period. Cattle producers routinely feed newborn calves fresh (ie, never frozen) or frozen colostrum, which contains antibodies against pathogens within the local environment; however, antibodies are not the sole constituents of colostrum and passively acquired immunity. …”

Optimizing manure management for enhancing millet yields and resources use efficiency under rehabilitated plinthosols in the Sahel por Ibrahim, A., Fatondji, D.

“…At the maturity stage, N, P and K absorbed by millet markedly exceeded nutrients released from manure irrespective of manure application period. Application of manure under M2 increased average millet grain yield by 50% and 14% compared to manure application under M1 and M3 modes, respectively. …”

Escape from CD8+ T Cell Response by Natural Variants of an Immunodominant Epitope from Theileria parva Is Predominantly Due to Loss of TCR Recognition por Connelley, Timothy K., MacHugh, Niall D., Pellé, Roger, Weir, William, Morrison, W. Ivan

“…In this study, we examined the TCR β-chain (TRB) diversity of the CD8+ T cell responses of cattle against two immunodominant epitopes from Theileria parva (Tp1214–224 and Tp249–59) and investigated the role of TCR recognition and MHC binding in determining differential recognition of a series of natural variants of the highly polymorphic Tp249–59 epitope by CD8+ T cell clones of defined TRB genotype. …”

Current state of knowledge on characterisation of farm animal genetic resources in Ethiopia por Ayalew, W., Getahun, E., Tibbo, Markos, Mamo, Y., Rege, J.E.O.

“…In the highlands, government sponsored crossbreeding programmes have severely compromised the sustenance of genetic diversity in indigenous livestock, especially cattle and poultry. Yet not much has been done to document the existing indigenous livestock breeds and the impacts of agricultural Development, increasing human populations and the booms and bursts in livestock population numbers associated with periodic good years and bad years. …”

Land-use change influence ecosystem services in an agricultural landscape in Central America por Tobar López, Diego E., Muriel, Bonin, Andrade, Hernán J., Ibrahim, Muhammad

“…It was estimated that forest cover was reduced by 93% between 1978 and 2011, whereas pasture areas increased considerably (133,304 ha) in the same period. These changes have caused a reduction of forest cover for cattle production, resulting in a loss in the quality and provision of ecosystem services. …”
