The objective of this study was to assess the effects of combined feed and health interventions on small ruminant production in mixed crop and livestock systems in southern Mali. Zanzoni village served as the control group while Sirakele received feed and health intervention. Twenty households were randomly selected in each community for a year-long study spanning the period August 2016 to August 2017.

In the West African Sahel, majority of farmers raise small ruminants for immediate source of income, as insurance against emergencies and as mitigating measures in case of crop failures (Wilson 1991). Besides, small ruminants also produce manure which is an invaluable source of organic matter for improving soil fertility. In Mali, about 90% of households own sheep and goats as they are important for the livelihood strategies of many resource poor rural households (Ba et al. 1996). Small ruminant rearing provides employment opportunities for rural women and youth as they are heavily involved in the management of sheep and goats (Wilson 1991;Lebbie 2004). The short generation intervals of small ruminants compared to cattle allows for rapid flock growth within a short provided there is adequate nutrition and veterinary care. Compared to cattle, small ruminants tend to withstand drought much better (Lebbie 2004). For example, Wilson (1991) reported that the during the drought of the early 1980s in the Sahel, cattle losses were over 80% while those of small ruminants were not more than 50% of the flocks."},{"index":2,"size":289,"text":"In view of the potential for rapid flock growth and the varied functions small ruminants fulfil in mixed crop and livestock systems, they could be a means of improving household food security and poverty alleviation among smallholder farmers. However, small ruminant production in Mali is challenged by the poor performance of animals largely due to inadequate nutrition and diseases (Wilson 1986;Ba et al. 1996). Given the low inputs into sheep and goats production by the smallholder farmers, their animals are rarely vaccinated or treated regularly against diseases (Ba et al. 1996) and supplementary feeding is often on an ad hoc basis (Ayantunde et al. 2014). Consequently, high mortality rate is common in small ruminant flocks in Mali (Ba et al. 1996) as well as in other Sahelian countries. One way in which mortality could be reduced is by vaccinating small ruminants against main diseases such as pasteurellosis, peste des petits ruminants (PPR) and deworming them. In addition to healthcare, strategic supplementation of the small ruminants is also essential to improve their performance ( The underlying hypothesis for this study was that combinations of improved management practices results in higher animal productivity, income, and household food security than single technologies. In this study, the interventions focused mainly on provision of healthcare and supplementary feeding. The objective of the study was to assess the effects of combined feed and health interventions on small ruminant production in mixed crop and livestock systems in southern Mali. The specific objectives were: (1) to assess the effects of feed and health package on sheep and goats live weight changes, flock dynamics (birth, death, offtake) and manure production, and (2) to quantify the costs and benefits of feed and health package in smallholder small ruminant production."}]},{"head":"Methodology","index":3,"paragraphs":[]},{"head":"Study sites","index":4,"paragraphs":[{"index":1,"size":236,"text":"The study was undertaken in Sirakelé (-5.48 o long; 12.51 o lat) and Zanzoni (-5.57 o long; 12.61 o lat) villages in Koutiala District in southern region of Mali. Sirakélé is a village in the rural commune of Songoua that is situated about 15 km north of Koutiala town, while Zanzoni is located in commune Fakolo about 35 km from Koutiala town. Koutiala District is the cotton production capital of Mali. Both study communities are in a region with a high concentration of smallholder crop and livestock farmers which implies that the mixed crop and livestock farming system is dominant. The two study sites have a Sudanian climate characterized by an alternation of dry and rainy seasons that last about six months each. The dry season is normally between November and April while the rainy season is between May and October. Annual precipitation varies between 750-1,100 mm. Crop farming and livestock husbandry are the main sources of household foods and income in the study areas. The feed resources in both study sites are similar as reported by Umutoni et al. (2015) from the study on the evaluation of feed resources in Koutiala and Bougoni districts in southern Mali.

Cotton seed cake was used as supplement in this study as it is readily available in the study sites due to widespread cultivation of cotton. The quantity of cotton seed cake offered was based on similar studies in Ghana where between 200 and 300 g of supplement was offered per animal (Konlan et al. 2017). Given that the experiment was undertaken on farm, physiological status was not considered while deciding the amount of supplement to be distributed to animals as it is difficult to adjust quantity offered to animal physiological status in rural farm conditions. The treatment package is referred to as 'Feedhealth (FH) intervention' in this report. Vaccines produced by the Malian Central Veterinary Laboratory (Laboratoire Central Vétérinaire de Bamako) named 'Ovipeste' and 'Pastovin' were used for vaccination against PPR and pasteurellosis, respectively. Sheep and goats under FH intervention were vaccinated once per year against PPR at the dosage of 1 ml per animal and twice per year against pasteurellosis at the dosage of 2 ml per animal.

For goats, the average flock size was 4.20±0.97 and 6.75±1.24 for the control and FH intervention groups, respectively. The results showed that the both sheep and goat flocks were dominated by females irrespective of the treatment. At least 80% of the sheep flock was female at the beginning of the study while at least 75% of the goat flock was female at the same period. These results agreed with the results on small ruminant production in the agro-pastoral systems in Central Mali by Wilson (1986) where it was reported that the females accounted for at least 75% of the sheep and goat flocks. Generally, the flock is dominated by female animals for reproduction and for flock growth, whereas the male sheep and goats are often sold to meet household cash needs as reported by Ba et al. (1996) that the offtake rate of male animals is often high compared to the female animals. The average flock size per household of sheep and goats at the beginning in our study sites in Koutiala district was lower than for the agro-pastoral sheep and goat flock in Central Mali reported by Wilson (1986) which were on average 9.48 and 23.57 for sheep and goats, respectively. The higher flock size of agro-pastoral flock than those of mixed croplivestock farmers in southern Mali is expected as the farmers in the south are more oriented towards cropping than raising livestock whereas the agro-pastoralists are livestock keepers by tradition though they have settled down to grow crops (Ayantunde et al. 2011)."},{"index":2,"size":247,"text":"After a year, the flock size of the control group remained largely the same as at the beginning of the study (sheep-male 0.65±0.22; female: 2.95±0.73; goats-male: 1.15±0.33; female: 3.45±0.72) whereas the flock size of sheep and goats per household under FH intervention doubled within the same period (Table 1). The total number of the flock for the FH group increased from 106 sheep at the beginning of the study (August 2016) to 236 at the end of July 2017 while the number of goats increasing from 135 to 252 (Figure 1). These results demonstrate that feed and health interventions led to significant increase in flock size of sheep and goats within a short period through better reproductive and growth performance. Similar results were reported by Ba et al. (1996) in Mali with introduction of health treatment alone. Konlan et al. (2017) also reported synergistic benefits of the combined effect of providing concentrate feed and healthcare to small ruminants kept by smallholder farmers in northern Ghana. A similar trend of significant increase in small ruminant number with feed and health intervention was reported by Avornyo et al. (2015) also in northern Ghana. Results on flock dynamics (Table 2) showed significant differences in birth rate, mortality rate and offtake rate between the control and feed-health intervention group. The mortality rate of the control group was 30.4% during one year of the study while that of the FH group was 13.3%, which was significantly lower than of the control group."},{"index":3,"size":359,"text":"The results confirmed that mortality rate is always high in a small ruminant flock without adequate healthcare and nutrition (Konlan et al. 2017). According to Wilson (1986), the mortality rate can be up to 30% in sheep and goat flock in extensive livestock systems where healthcare is inadequate and nutrition can be poor, particularly in the dry season. Ejlertsen et al. (2012) reported mortality rates of 25-32% for sheep flock and of 13-23% for goat flock in southern Mali based on a recall survey. The major causes of death in the flocks in our study were diseases such as respiratory problems, diarrhoea and fever, losses due to predator and injuries. Similar causes of death were reported by Ba et al. (1996) for small ruminant flock in semi-arid areas of Mali. The results on repartition of birth and death in the control and FH groups between September 2016 and August 2017 are presented in Figure 2 and Figure 3. Most births tended to occur between March and September (Figure 2) while deaths tended to occur throughout the year though the lowest recorded cases of death were in January and February. Wilson (1986) for small ruminants in agro-pastoral systems in central Mali. Offtake generally tended to be much higher in males than in females as the major reason for offtake is sale to meet immediate cash needs of the households and the males are often targeted for this (Ba et al. 1996). In our study, we did not collect sexdisaggregated data for the offtake but the anecdotal evidence from the participating households supports the claim that offtake is higher in males than in females. Generally, offtake is influenced by the number of animals available, immediate cash needs, prevailing market prices and animal's age and condition. Interventions that lead to significant increases in flock size like supplementary feeding and healthcare will tend to increase offtake as shown by the significant difference between the offtake rate of the control group and the feed-health group in our study. In Mali and other Sahelian countries in West Africa, sale of small ruminants is one of the key strategies for coping with crop failures (Lebbie 2004)."}]},{"head":"Body weight development and change","index":12,"paragraphs":[{"index":1,"size":200,"text":"The results of this study showed that feed and health intervention had significant effect on body weight development and the average daily gain (ADG) of sheep and goats (Table 3). The average daily gains of sheep and goats in the control group were 16.58±2.74 and 22.59±2.29 g/day while the ADG for the animals that received feed and health intervention was almost double (sheep: 47.12±2.73; goats: 42.98±3.28). For the few lambs and kids that were weighed at birth, the birth weights were similar for both control and treatment groups. The body weight development trend was similar until the fourth month for sheep (Figure 4a) and until the fifth month for goats (Figure 4b) under both control and treatment groups.

The higher body weight of sheep and goats as from 4 months of age showed that the effect of supplementary feeding and healthcare on body weight development is cumulative."}]},{"head":"Manure production and nutrient content","index":13,"paragraphs":[{"index":1,"size":429,"text":"Results of manure collected from sheep and goats by households under control and feedhealth intervention are presented in Table 4. More manure was collected by the households that received feed-health intervention than by those under control across all seasons (early dry, late dry and wet seasons). This suggests that feed and health intervention is also beneficial for soil fertility improvement as the farmers could collect more manure to apply to their crop fields. The main challenge of manure collected at homesteads is transportation to the crop field, particularly if the farm is far from the village. The manure collected per animal per day was highest for both groups (control: 102±4.06 g DM/animal/day; feed-health: 121.52±4.52 g DM/animal/day) in the late dry season while it was lowest in the wet season. This could be attributed to longer time spent around the homestead by the animals in the late dry season as there was virtually no feed in the grazing areas at this period which allowed for more manure to be collected. In the wet season, it is generally more difficult to collect manure as the water content in faeces is high. The quantities of manure collected from animals in both groups when expressed in g DM/kg live weight/day (Table 4) were much lower than the quantities of 10 to 13 g DM/kg live weight/day reported by Ayantunde et al. (2007) for sheep under feeding trials using faecal collection bags. This shows that there were losses in the collection of the manure by the farmers in this study. Besides, the manure deposited by the animals during grazing could not be collected which also explains the lower quantities of collected manure in this study. Manure nitrogen and phosphorus contents were similar for both control and treatment groups except in the wet season when the nitrogen content was higher for the feed-health group than the control. The values of nitrogen and phosphorus concentration in the manure found in this study were much higher than those reported by Ayantunde et al. ( 2007) from feeding trials with sheep fed on groundnut haulms as supplement in the early dry season in Niger. In their study, the nitrogen concentration ranged from 10.7-12.8 g/kg DM and the phosphorus concentration ranged from 1.9-2.8 g/kg DM. The higher values could be partly attributed to better quality feed in southern Mali than the millet straw as basal feed and groundnut haulms as supplement used in the feeding trials by Ayantunde et al. (2007) as high nutrient feed will generally result in higher nutrient content of the manure (Ayantunde et al. 2018)."},{"index":2,"size":99,"text":"In addition, the higher values obtained in this study could be attributed to contamination as manure collected might have been contaminated by urine, feedstuffs offered to the animals and dust. Given that manure collected by the households for application to the crop field is often a mixture of faeces and urine, our results give an indication of nutrients that may return to the soil. Higher manure nitrogen and phosphorus outputs were observed for manure collected by the households under the feed-health intervention than those in the control group which again confirms that better nutrition results in better manure quality."},{"index":3,"size":167,"text":"The results on repartition of manure collected per household flock and per animal are presented in Figure 5 and Figure 6. The results showed that the quantity of manure collected per household per day tended to increase linearly from September 2016 to August 2017 for the feed-health group while it remained almost the same for the households in the control group (Figure 5). When expressed as quantity collected per animal per day, the quantity collected was between 100-120 g DM/animal/day for the feed-health group while the values for the control group were between 80-100 g DM/animal/day (Figure 6). In view of the importance of animal manure for soil fertility in West African Sahel, the more manure that could be collected, the better for the smallholder farmers as manuring leads to increased crop yield (Ayantunde et al. 2018). The main challenge is maintaining the appropriate number of animals to provide adequate manure.

The common crop residues included sorghum stover, cotton straw, cowpea hay and groundnut haulms (Table 5) while the agro-industrial by-products were cotton seed cake and maize bran. Cotton seed cake had the highest crude protein among the feed resources offered to sheep and goats by the farmers in the two treatments."},{"index":2,"size":206,"text":"The legume residues (cowpea hay and groundnut haulm) were also high in crude protein and in vitro organic matter digestibility. The browses (leaves of shrubs and trees) are important feed resources in the late dry season when there is feed scarcity (Umutoni et al. 2015) and they generally have high crude protein content, but they are high in lignin content (Table 5). The values of crude protein content of the cowpea hay and groundnut haulm in this study were higher than those reported by Umutoni et al. (2015) which could be attributed to period of collection of the feed samples and the associated differences in the leaf: stem ratio. The legume residues like cowpea hay and groundnut haulms are normally collected and stored and used to feed household animals in the dry season or sometimes sold as the prices are often high (Ayantunde et al. 2014). The cereal straws are normally left on the crop field to be grazed by the animals. However, some farmers collect and store them at homestead to feed their flock. The quantity and quality of feed resources available decreased as the dry season progressed. Also, the importance of crop residues decreased as the dry season progressed while that of browse increased.

The sources of revenue were weight gained, manure collected and animal sale (offtake; Table 6) while the costs were associated with veterinary care and feed cost. The results showed that traditional small ruminant production with low inputs is profitable provided there is no major disease outbreak, which could explain the reason for widespread rearing of small ruminants by smallholder farmers. However, the farmers can generate more revenue through small ruminant production by providing supplementary feed and healthcare for their animals. For households with a large flock size, it is prudent and profitable to provide supplementary feed and standard healthcare (vaccination against PPR and pasteurellosis, deworming and curative measures) to their animals as the risk is high of losing most of the animals in the event of major disease outbreak like PPR with reported mortality rate of 80% (2011) were to be adjusted to the flock size in our study, the annual profits in our study will be higher than the returns from dairy sheep and goats.

The daily collection of manure also made them clean the animal pens and sheds."},{"index":6,"size":112,"text":"The feedback from farmers in both Sirakelé and Zanzoni suggests that building their capacity in animal husbandry is essential to improving small ruminant production in mixed crop and livestock systems in Mali and in other Sahelian countries in West Africa. Also building awareness of the benefits of small ruminant rearing can motivate farmers to invest in better management of their flocks. For example, construction of pens or hangars for housing the animals will facilitate collection of animal manure for application for crop farming. Extension services, which are weak in Mali and in other countries in the region, need to be strengthened to build the capacity of the farmers in improved animal husbandry."}]}],"figures":[{"text":" Ben Salem and Smith 2008; Nantoume et al. 2011; Konlan et al. 2017).
