With increased search for least-cost alternative feed resource in animal production, this study was conducted to determine the visual properties, chemical composition and cost analysis of three differently processed discarded vegetable-bovine blood-rumen content mixture as potential alternative feed resource. These mixtures were obtained by mixing whole bovine blood, discarded vegetable and rumen content at ratio 1:1:1 under different processing methods. The processed mixtures obtained were in three categories: discarded vegetable-fresh bovine blood-fresh rumen digesta (D1), discarded vegetable-ensiled bovine blood-fresh rumen digesta (D2) and discarded vegetable-fresh bovine blood-ensiled rumen digesta (D3). The mixtures were cooked and sun-dried to constant moisture content and thereafter were subjected to particle size reduction. Chemical composition of the products indicated a good potential nutritional quality with metabolizable energy and crude protein contents ranging from 9.66 to 10.49 MJ/kg and 40.79 to 50.21, respectively. Crude fibre concentrations were relatively low (8.39-13.14) for most of the products compared to conventional protein sources. Visual assessment of processed mixtures revealed D1 to be brownish in colour while D2 and D3 tend towards grey. In terms of odour, all three test mixtures were strongly pungent. Processed mixture D1 had an intermediate texture (it was neither finely ground nor coarse) where D2 and D3 had a finely ground texture. Cost analysis revealed a lower production cost for the three processed mixtures indicating its adequacy to replace soybean and other plant and animal protein sources in terms of their cost/kg inclusion in diet. Processed mixtures can serve as suitable replacements for soybean meal in terms of chemical constituents and reduced cost/kg feed for animal.

This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and that had AMEn and TMEn values obtained by the total excreta collection method from growing broiler chickens and the chemical composition in crude protein (CP), ether extract (EE), mineral matter (MM), gross energy (GE), calcium (Ca) and phosphorus (P). The general equation obtained to estimate AMEn values of poultry offal meal was: AMEn = -2315.69 + 31.4439(CP) + 29.7697(MM) + 0.7689(GE) - 49.3611(Ca), R² = 72%. For meals with high fat contents (higher than 15%) and low mineral matter contents (lower than 10%), it is suggest the use of the equation AMEn = + 3245.07 + 46.8428(EE), R² = 76%, and for meals with high mineral matter content (higher than 10%), it is suggest the equations AMEn = 4059.15 - 440.397(P), R² = 82%. To estimate values of TMEn, it is suggested for meals with high mineral matter content the equation: TMEn = 5092.57 - 115.647(MM), R² = 78%, and for those with low contents of this component, the option is the equation: TMEn = 3617.83 - 15.7988(CP) - 18.2323(EE) - 96.3884(MM) + 0.4874(GE), R² = 76%.

Abstract Background The study highlighted the potential of three common and under-utilized tropical leguminous seeds (Tomentosa nilotica, Dioclea reflexa and Monodora myristica) to be used as supplementary feed to ruminant livestock. These seeds (their plants inclusive) are valuable sources of food and medicine for the prevention of illness and maintenance of human health. The medicinal properties of these seeds include antimicrobial, anti-inflammatory, anti-oxidant and immuno-stimulant. Trypsin inhibitors, which are common anti-nutritional factors in legumes and for monogastric animals, do not exert adverse effects in ruminants because they are degraded in the rumen. Hence, the crux of this study is to examine the effect of processing methods on the nutritional composition (proximate, fibre fractions, minerals, anti-nutrients) and in vitro digestibility of Tomentosa nilotica, Dioclea reflexa and Monodora myristica seeds and their suitability as feedstuff (protein sources) in small ruminant feed, particularly during off-season. Results From the results, raw Tomentosa nilotica and Monodora myristica have the highest crude protein (30.35% CP) and fat (22.40% EE), respectively. It is noteworthy that roasting best improve the mineral and significantly reduce the anti-nutrients observed in this study better compared to boiling and soaking methods. The highest organic matter digestibility, short-chain fatty acids, metabolizable energy and in vitro dry matter digestibility values were obtained in Dioclea reflexa compared to other test seeds. Roasting best improved the nutritive values, while Dioclea reflexa seed was rated highest for all the nutritional attributes and in vitro digestibility. Conclusions Dioclea reflexa could be incorporated in ruminants’ diet as protein source, particularly during the off-season, for improved ruminant production in Nigeria. However, in vivo study is therefore recommended to validate this report.

Forest rangelands contribute largely to goat diets in the Mediterranean area. Information about browsed plant quality is essential for adequate feeding management. The purpose of this study was to evaluate the temporal changes in chemical composition and in vitro digestibility of the main plant species selected by goats in the Southern Mediterranean forest rangeland during two consecutive years; these were very contrasted (dry and wet). The browsed species were composed of herbaceous, eleven shrubs, and four tree species. Overall, large variability in chemical composition, in vitro organic matter digestibility (IVOMD), and metabolizable energy (ME) was observed among species, grazing season (spring, summer, and autumn), and years within each species. Crude protein (CP) content varied from 60 to 240 g/kg dry matter (DM). The fiber fractions, except for Quercus suber, increased significantly by advancing maturity. Due to the water stress, the lignin level presented a higher value during the spring of the dry year. Condensed tannin (CT) content varied from 2 to 184 g/kg DM. CP, IVOMD, and ME showed a negative correlation with lignin and CT. Based on the results presented herein, it is concluded that the nutritive value of the browsed plant species was highest in the spring and lowest during the summer and autumn of both studied years. With a good grazing management strategy, the selected plant species by goats could guarantee high-quality feeding resources throughout the year.
