“…Feed conversion efficiency could be increased by adjusting the total amount of feed offered to the animals' true needs of protein and energy. On the other hand, yearround growth rates of HI sheep/goats were higher than the 40 g/day reported for sheep fed groundnut haulms elsewhere in Niger (Ayantunde et al, 2007), the 56 g/day obtained for Sahelian goats fed pods of Acacia senegal Willd in Northern Burkina Faso (Sanon et al, 2008) and the 63 g/day obtained in goats grazing dry season rangeland in semi-arid Mali (Sangaré and Pandey, 2000). Concerning cattle, although amounts of DM, energy and nutrients offered in the HI units exceeded the requirements of dairy cattle in all seasons, daily weight gains were low in the rainy and the cool dry seasons, while cattle lost weight in the hot dry season.…”

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.

“…In concordance with this, Hakyemez et al (2009) investigated the potential use of natural pastures for high yielding dairy goats and found that CP content of the pasture decreased but the structural carbohydrates increased as the grazing season proceeded. However, Sanon et al (2008) concluded that forage eaten by goats with a CP content of above 10 g/ 100g DM, have potential for improving N to ruminants.…”

The study was conducted in the south-west Tlaxcala, Mexico. Two simultaneous trials were carried out in range goats, during dry and wet seasons, to determine the nutritive value of selected forages and dry matter intake (DMI) using Cr 2 O 3 . The crude protein (CP) content varied from 2.89 to 19.8 g/100 g, and acid detergent fiber (ADF) from 23.4 to 67.7 g/100 g. The highest CP content was in the plants Simpsia amplexicahuale and Senecio salignus. The ADF and ash contents increased in dry season (p B0.05). Conversely, dry matter digestibility (DMD) increased in wet season (p B0.05). DMI of goats was 98.1 and 90.3 g/kg LW 0.75 (p B0.01) for dry and wet season, respectively. In dry season protein requirements of goats were fulfilled only by S. salignus. In wet season, all evaluated plants covered the requirements of CP for maintenance. Simpsia amplexicahuale and Bouvardia ternifolia showed outstanding CP and DMD.

“…Le fourrage ligneux est davantage plus abondant dans le bol alimentaire des ruminants durant la saison sèche (Botoni, 2003). L'utilisation des fourrages des espèces ligneuses dans l'alimentation animale a suscité au Burkina Faso plusieurs travaux de recherches sur l'identification des ligneux fourragers et les valeurs nutritives de leur fourrage (Kaboré-Zoungrana, 1995 ;Zoundi et al, 2002 ;Kaboré-Zoungrana et al, 2008;Sanon et al, 2008 ;Zampaligré, 2012). La plupart de ces études concernent les matières sèche et organiques, les constituants chimiques (matière azotée totale, matières, fibres) l'ingestibilité du fourrage et la digestibilité des matières organiques et azotées totales, des constituants pariétaux et quelquefois sur les tanins.…”

RESUMELes antinutritionnels ont été le plus souvent ignorés dans l'évaluation de la qualité des fourrages ligneux dont la part augmente continuellement dans le bol alimentaire des ruminants au Burkina Faso. L'objectif de l'étude a été de caractériser et de quantifier les coumarines dans les feuilles et/ou les fruits de 15 ligneux fourragers couramment appétés par les ruminants à Diarabakoko et Dionona. Des tests de caractérisation en tubes ont été réalisés sur les échantillons frais collectés pour détecter la présence des coumarines. Des dosages spectrophotométriques des coumarines ont été également réalisés à partir des extraits frais des échantillons. L'étude a révélé la présence des coumarines chez toutes les espèces à des teneurs oscillant respectivement entre 10,590 ±0,354 et 31,174±0,477 µg EC/g d'extraits frais des feuilles et entre 1,250 ±0,014 et 22,899±0,561 µg EC/g d'extraits frais des fruits (P˂0,05). L'analyse des variances a permis de distinguer 2 classes de teneurs en coumarines des feuilles dont la première a les plus faibles valeurs. Nos résultats constituent des critères supplémentaires pour le choix des ligneux fourragers en aménagement pastoral et en agroforesterie. Ils montrent aussi que le fourrage (feuilles et fruits) des espèces étudiées peut contribuer sans danger à la supplémentation des ruminants.
