Six sheep were randomly allocated to each of the four treatment diets: Rhodes grass (Chloris gayana) hay offered ad libitum (T1), hay + 150 g moringa leaf (T2), hay + 300 g moringa leaf (T3), hay + 450 g moringa leaf (T4) were offered daily. A 7-day digestibility trial and an 84-day growth experiments were conducted. Dry matter (DM), organic matter (OM) and crude protein (CP) intakes increased (P < 0.05) with increasing levels of moringa leaf in the diets. Sheep fed T2, T3 and T4 diets gained (P < 0.05) 40.2, 79.1 and 110.1 g/head/day, respectively, while the control group (T1) lost weight (−13.3 g/head/day). The apparent digestibilities of DM, OM, neutral detergent fibre and acid detergent fibre were similar (P > 0.05) among treatments. The digestibility of dietary CP increased (P < 0.05) with increasing levels of moringa leaf, but there was no significant difference between T2 and T3 diets. The nitrogen (N) intake and urinary N excretion increased (P < 0.05) with increasing levels of moringa leaf. The N retention was highest (P < 0.05) for 450 g moringa leaf supplementation. The control group was in a negative N balance. Supplementing a basal diet of Rhodes grass hay with dried moringa leaves improved DM intake, BWG and N retention. It is concluded that M. stenopetala can serve as a protein supplement to low-quality grass during the dry season under smallholder sheep production system.

Twenty-five yearling buck goats (15.8 ± 1.4 kg) were assigned into five treatments in a randomized complete block design: natural grass hay alone (T1) or supplemented with 100% CSM (T2), 67% CSM + 33% E. brucei (T3), 33% CSM + 67% E. brucei (T4), and 100% E. brucei (T5) on dry matter (DM) basis. Supplemented goats consumed more (P < 0.05) total DM and organic matter (OM) than the non-supplemented group, but the intakes were not influenced (P > 0.05) by the proportion of the supplements. The highest (P < 0.05) crude protein (CP) intake was observed in goats supplemented with CSM alone, whereas the lowest intake was observed in the non-supplemented group. Total CP intake decreased (P < 0.05) with increasing levels of E. brucei in the supplement mixture. The supplemented goats gained more (P < 0.05) weight than the control group. Apparent DM and OM digestibility was higher (P < 0.05) in supplemented goats than in the non-supplemented ones, but similar (P > 0.05) among the supplemented group. The digestibility of CP was higher (P < 0.05) for supplemented goats, except in those goats fed E. brucei alone, than the non-supplemented group. Slaughter weight, empty body weight, hot carcass weight, dressing percentage, rib eye muscle area, and total edible offals were higher (P < 0.05) for supplemented goats than for the non-supplemented ones. It could be concluded that E. brucei could be used as a substitute to CSM under smallholder production systems.

Research paper thumbnail of Feed intake, digestibility, nitrogen utilization, and body weight change of sheep consuming wheat straw supplemented with local agricultural and agro-industrial by-products

Tropical Animal Health and Production, 2010

Effects of supplementing sheep consuming wheat straw with local agro-industrial by-products on fe... more Effects of supplementing sheep consuming wheat straw with local agro-industrial by-products on feed intake, growth, digestibility and nitrogen utilization were determined. Thirty 1-year-old local wethers, with a mean (±SD) live weight of 19.8 (±1.06) kg, were assigned to five treatments: wheat straw + atella (T1), wheat straw + atella + poultry litter (T2), wheat straw + atella + coffee pulp (T3), wheat straw + atella + coffee pulp + poultry litter (T4), hay + concentrate (T5). A 7-day digestibility experiment and a 112-day growth trial were conducted. Total dry matter (DM) and organic matter (OM) intake as well as body weight gain was similar for all treatments. The highest (P < 0.05) nitrogen (N) intake was in sheep fed T1 and T4 diets, while the lowest was in those fed T2 and T5 diets. Sheep fed T1 and T2 diets had greater (P < 0.05) DM and OM digestibility than those fed T4 and T5 diets. The highest (P < 0.05) digestibility of N was for the T2, T4, and T5 diets, while the lowest was for the T1 diet. The highest N retention was in T4 diet, whereas the lowest was in T3 diet. In conclusion, in urban and peri-urban areas where atella, poultry litter, or coffee pulp are available, smallholder farmers could feed the mixtures as a supplement to straw with a good performance without using concentrate feeds.

Research paper thumbnail of Feeding value of enset ( Ensete ventricosum ), Desmodium intortum hay and untreated or urea and calcium oxide treated wheat straw for sheep

Journal of Animal Physiology and Animal Nutrition, 2009

Feed intake, in vivo nutrient digestibility and nitrogen utilization were evaluated in male sheep... more Feed intake, in vivo nutrient digestibility and nitrogen utilization were evaluated in male sheep fed different fractions (leaf, pseudostem, corm, whole plant) of enset, untreated or 2% urea- and 3% calcium oxide- (CaO or lime) treated wheat straw and Desmodium intortum hay as sole diets. All feeds, except D. intortum hay and enset leaf had low crude protein (CP) content. Non-fiber carbohydrate contents were higher in enset fractions, especially in pseudostem and corm relative to other feeds. Enset leaf and pseudostem had high calcium, phosphorus and manganese contents. Corm, whole enset and D. intortum hay were rich sources of zinc. Daily dry matter and CP intakes were higher (p < 0.05) in sheep fed D. intortum hay (830 and 133 g, respectively) than those fed pseudostem (92 and 7.8 g, respectively). Organic matter digestibilities were highest for corm (0.780) and whole enset (0.776) and lowest for D. intortum hay (0.534) and untreated wheat straw (0.522). The CP digestibility ranged from 0.636 in D. intortum hay to 0.408 in corm. Nitrogen (N) balance was highest (p < 0.05) in D. intortum hay (10.4 g/day) and lowest in corm (−1.3 g/day). Enset leaf could be a useful protein supplement whereas the pseudostem and corm could be good sources of energy.

Samples of leaf lamina, leaf midrib, pseudostem and corm were taken from ten enset varieties at the age of 5 to 6 years during the main rainy season. The dry weight of each variety and fraction were also determined. Mineral contents in fractions of different enset varieties were analysed and compared with nutrient requirements of ruminants. The contribution of different enset fractions to the total dry weight was variable (P < 0.05), the highest being from pseudostem and the lowest from leaf lamina. There were varietal differences (P < 0.05) in macro and trace mineral content in different fractions except phosphorus (P) content of leaf lamina. Most enset fractions were rich sources of major minerals such as P, potassium (K), calcium (Ca) (except corm) and magnesium (Mg). Sodium (Na) content was very low. Most fractions were rich in iron (Fe) and manganese (Mn), but deficient in copper (Cu), except leaf lamina. Zinc (Zn) content was high in corm, but low in other fractions. This account of the macro and trace mineral content of different enset varieties and fractions could help in strategic supplementation intended to alleviate mineral deficiencies.

One hundred twenty dairy farms, (60 from urban and 60 from rural dairy production system) were selected for the study randomly. A structured questionnaire was prepared and an interview of each household was carried out to collect data on demographic and characteristics of households, livestock holding and composition, objective of dairying, available feed resources and feeding practices ,dairy cattle feeding management practices and constraints of dairy cattle. The common feed samples which were used in urban and rural sites available across the different season were randomly collected. Descriptive statistics was used to analyze the data using SPSS. The average family size of the households was 5.7 for urban and 6.1 for rural. Average farm size of households in the rural production system was 0.73 ± 0.07 ha. There was no significant difference (p<0.05) in cattle holding between urban and rural systems. Purpose of cattle keeping was for milk sale, milk and meat, for home consumption, security and income source .The major feed resources available were natural pastures, crop residues, improved forages and pasture and agro-industrial by-products (AIBP). About 657 total dry matters (tDM) per household per annum was produced from all feed resources in rural kebeles, whereas about 1104 tDM was the total annual requirement. There was a deficit of about 60%. The major constraints hindering dairy production were feed scarcity, land/space limitation and high cost of animal feed .In urban area, the highest (P<0.05) CP content was for Sesbania whereas the lowest (P<0.05) was from natural pasture for roughages . Sesbania had the highest (P<0.05) IVDMD while the lowest was for natural pasture. Linseed had the highest (P<0.05) CP content and IVDMD. In the rural area, among roughage feeds natural pasture had the lowest (P<0.05) CP content while the highest (P<0.05) was for Sesbania. The IVDMD for desho were higher than the other feedstuffs. Linseed cake had the highest (P<0.05) CP content. Among the AIBP, mixed ration and linseed cake had the highest (P<0.05) IVDMD. In conclusion unless efforts are made to meet the nutrient requirements of dairy cattle through proper feed management and supplementation it is not possible to optimize the milk production potential of dairy cows. It is necessary to supply adequate amount of feed all year round through treatment of crop residues which are the dominant feedstuff and supplementation with tree legumes.

The apparent digestibilities of DM, OM, neutral detergent fibre and acid detergent fibre were similar (P > 0.05) among treatments. The digestibility of dietary CP increased (P < 0.05) with increasing levels of moringa leaf, but there was no significant difference between T2 and T3 diets. The nitrogen (N) intake and urinary N excretion increased (P < 0.05) with increasing levels of moringa leaf. The N retention was highest (P < 0.05) for 450 g moringa leaf supplementation. The control group was in a negative N balance. Supplementing a basal diet of Rhodes grass hay with dried moringa leaves improved DM intake, BWG and N retention. It is concluded that M. stenopetala can serve as a protein supplement to low-quality grass during the dry season under smallholder sheep production system.
