“…This has spurred urban demand for food, mainly for cereals, pulses and livestock products (Tiffen, 2004;Pistocchini et al, 2009). In the region, urban livestock husbandry has become increasingly widespread as a source of food, income and employment, savings and as an insurance system (Ferná ndez-Rivera et al, 2005;Thys et al, 2005;Ayantunde et al, 2007).…”

“…These high livestock numbers translate into an important demand for livestock feeds that can not be supplied from the urban area alone but also relies on the rural surroundings (Guendel, 2002;Graefe et al, 2008); Araya et al (2007) state that livestock keepers in larger towns recurrently face problems in obtaining sufficient feed and water for their animals. With an increased consumption of livestock products of Niamey's rapidly growing population (Pistocchini et al, 2009) and the hope to benefit from this demand, intensive supplementation systems have evolved among the urban and peri-urban livestock (ULP) farmers (Tiffen, 2004). Animals are kept in small sheltered enclosures at the homestead and are fed crop residues and other available waste products (Ferná ndez-Rivera et al, 2005).…”

Urban livestock husbandry receives growing attention given the increasing urban demand for livestock products. At the same time, little is known about the resource use efficiency in urban livestock enterprises and eventual negative externalities. In livestock production, feeds are an important resource whose nutrients are transformed into products (meat and milk) to generate financial return to the producer. The lack of knowledge on nutrient supply through feed might lead to oversupply with severe environmental impacts. In Niamey, a typical West African city and capital of the Republic of Niger, urban livestock production is constrained by feed scarcity, especially during the dry season. Here, the issue of resource use efficiency was studied in 13 representative and differently managed sheep/goat and cattle enterprises characterized by high and low feed inputs, respectively, during a period of 28 months. Nitrogen (N), phosphorus (P) and potassium (K) inflows into each farm through livestock feeds and outflows through manure were determined using a semi-structured questionnaire; interviews were accompanied by regular weighing of feed supplied and dung produced. Live weight gain (LWG) and efficiency of conversion of total feed dry matter offered (kg TDMO/kg LWG) were computed along with nutrient balances (NBs) per metabolic body mass (kg 0.75 ). NBs (per kg 0.75 /day) in the high-input (HI) sheep/goat enterprises were 11762.4 mg N, 1127.2 mg P and 11363.5 mg K and were significantly greater (P , 0.05) than those in low-input (LI) units (169.1 mg N, 298.3 mg P and 116.5 mg K). In HI cattle enterprises, daily balances averaged 1454.1 mg N, 140.1 mg P and 1341.8 mg K compared to 134.4 mg N, 29.0 mg P and 168.3 mg K (P . 0.05) in LI cattle systems. All systems were characterized by poor conversion efficiencies of offered feed, which ranged from 13.5 to 46.1 kg TDMO/kg LWG in cattle and from 15.7 to 43.4 kg TDMO/kg LWG in sheep/goats. LWG in HI sheep/goats was 53 g/day in the rainy season, 86 g/day in the hot dry season and 104 g/day in the cool dry season, while HI cattle lost 79 g/day in the hot dry season and gained 121 g/day and 92 g/day in the cool dry and rainy seasons, respectively. The data indicate that there is nutrient wasting and scope for improvement of feeding strategies in Niamey's livestock enterprises, which might also decrease nutrient losses to the urban environment.

Typical dairy products in Africa from local animal resources

Milk is recognised as an important element of the pastoral civilisations in Africa, where it has not only an economic value, but also a social and cultural value. The objective of this review is to identify the main African dairy products, mainly focussing on typical production processes based on the use of local animal resources. To this aim, dairy products were classified into five categories, according to the type and the production method: fresh cheese, ripened cheese, fermented milk, butter and dairy by-products. These categories give rise to an extraordinary range of local products where tradition, culture, and environmental conditions and constraints play a major role in contributing to this diversification. In some countries, some attempts are being made in order to valorise the local dairy products by establishing Slow Food Presidia or including them in the Ark of Taste compiled by Slow Food. One of the main constraints that limits the commercialisation and export of African dairy products is related to the scarce hygiene in milk production and processing, and the frequent absence of starter cultures, which result in products with non-standardised characteristics, short shelf life and high spoilage susceptibility, with consequent risks for human health. Efforts should be made to support the dairy products chain in Africa, by making production processes safer and by valuing local resources, in order to expand the internal market and the export opportunities. Development cooperation projects may play an important role in this respect and should therefore be encouraged. ARTICLE HISTORY

“…None of the farmers tied the cow's tail during milking, had an appropriate milking parlor or washed hands before milking. Milk production practices influence bacterial contamination at the barn level, and poor hygienic standards at the farm can affect the rest of the dairy production chain, as exemplified in studies from Uganda (Grimaud et al, 2007), Mali (Bonfoh et al, 2003(Bonfoh et al, , 2005, Ghana (Donkor et al, 2007), Kenya (Ogola et al, 2007), South Africa (Beukes et al, 2001), Niger (Harouna et al, 2009;Pistocchini et al, 2009); and Burkina Faso (Millogo et al, 2008(Millogo et al, , 2010. In addition, milk storage, transport and transformation process, can all present sources of microbial contamination (Bonfoh et al, 2005(Bonfoh et al, , 2006Grimaud et al, 2007;Millogo et al, 2008).…”

“…Biological contaminants in the food chain are viruses, bacteria, fungi and parasites (Bourgeade et al, 1992;FAO/WHO, 2008), which may come from a multitude of sources. Several studies showed that fresh milk and milk products are highly contaminated with zoonotic pathogens in West African capital cities (Bonfoh et al, 2003;Pistocchini et al, 2009), and contamination of dairy products with contagious non-zoonotic pathogens was also reported (Bonfoh et al, 2003(Bonfoh et al, , 2005Harouna et al, 2009;Wullschleger, 2009). While the former present a direct threat to consumer health, the latter may especially constitute a problem for the health and productivity of dairy animals (Bonfoh et al, 2003;Harouna et al, 2009).…”

Despite their contribution to food security, animal products and vegetables from urban and peri-urban agriculture (UPA) often raise public health and environmental concerns, given high use of agrochemicals, organic fertilizers and wastewater. This study exemplarily investigated contamination of selected horticultural and livestock products (milk and irrigated lettuce with a potentially high microbiological contamination; and tomato and cabbage on which various pesticides were used) from Bobo Dioulasso (Burkina Faso) and Sikasso (Mali). Samples of irrigation water, organic fertilizer and lettuce were collected from six gardens; cabbage and tomato samples were collected from 15 gardens, and samples of raw and curdled milk were collected from six dairy herds in February, May, and November 2009. Thermo-tolerant coliforms and Escherichia coli in irrigation water significantly exceeded WHO recommendations for unrestricted irrigation of vegetables consumed raw. Microbial contamination of lettuce at garden level and market place in Bobo Dioulasso, and at garden level in Sikasso was higher than at Sikasso market (P<0.05). Pesticide residues were detected in only one cabbage and one tomato sample and were below the maximum residue limit for consumption. Counts of thermo-tolerant coliforms and E. coli were higher in curdled than in raw milk (P<0.05). Given the differences in microbial load between produce of different origin and subsequent stages along value chains, there is scope for low-cost improvement of the safety of UPA smallholders' products. However, studies of higher spatial and temporal resolution along all stages of the value chains for these products are needed in order to derive respective recommendations.
