Nutritive value of three tropical forage legumes and their influence on growth performance, carcass traits and organ weights of pigs

Legumes are a very diverse source of food for humans and animals. Generally pulse legumes are used as human foodstuffs while pasture, shrub and tree legumes are more suitable and frequently used as a supplement to low quality feedstuffs for ruminant animals. The importance and potential of forage legumes is due to their diversity, compositional, agronomic and nutritional attributes.In many of the ruminant production systems of the developing world, native or naturalised grass pastures make up the bulk of the feed. The low quality and seasonal nature of the forage supply, together with the low intake by animals and the poor digestibility of the forage are major factors which contribute to low productivity of ruminant animals. There is thus substantial scope for the utilisation of the large array of forage legumes as a supplement for ruminant diets, especially in the arid and semi-arid tropics. Although the potential of forage legumes is high there is relatively little information on the vast array of materials available. There is some evidence, however, that some forage legumes have low digestibilities and contain a considerable variety of antinutrients and toxins which influence their nutritive value (Mueller-Harvey and Reed, 1992; D’Mello & Acamovic, 1989, Acamovic et al, 1992; Baintner et al, 1992; Jones et al, 1992; Topps, 1992).

The aim of this study was to evaluate the effect of dietary supplementation with Agave fourcroydes powder on growth performance, carcass traits, organ weights, gut morphometry, and blood biochemistry in broiler rabbits. A total of 40 male rabbits (New Zealand × Californian) weaned at 35 d were randomly selected for a control diet (CD) and CD + 1.5% of A. fourcroydes powder, with 10 replicates and two rabbits per replicate. After 60 d, A. fourcroydes powder increased body weight, feed intake, and weight gain (P<0.05), without affecting feed conversion ratio and viability (P>0.05). Furthermore, this natural product did not affect the edible portions and the indicators determined in the Longissimus dorsi, nor the organ relative weights and the intestinal morphometry (P>0.05); however, a decrease in cecal pH was observed and consequently an increase in cecal beneficial bacteria (P<0.05) were found. Also, A. fourcroydes powder reduced (P<0.05) the serum concentration of glucose, harmful lipids, HDL and atherogenic index although without change for the ureic nitrogen, creatinine and VLDL (P>0.05). Agave fourcroydes powder as a zootechnical additive promoted better growth, in addition, it showed lipid-lowering and hypoglycemic effects, without modifying the edible portions and organs digestive.

Fibre Fraction

Condensed tannins have been implicated in reducing the nutritive value of potentially important feedstuffs, largely through reducing protein and fibre digestion. Tannins can mediate their effects directly by binding to the protein or fibre fraction rendering them resistant to digestion, or indirectly by binding with digestive enzymes, preventing their catalytic action. These adverse effects of tannins, however, can be mitigated by the use of agents such as polyethylene glycol (PEG) which form complexes with condensed tannins rendering them less effective as protein and fibre-binding agents. In this study, the effects of polyethylene glycol on (a) the in vitro fermentability and (b) the digestibility of the fibre fraction (= non-starch polysaccharide; NSP) of leaves of six tropical forage legumes varying in condensed tannin content was investigated.The species used, chosen for their varying tannin contents, were Sesbania goetzei (SG), S. seban (SS), Leucaena leucocephala (LL), Dioclea guianensis (DG) Calliandra sp. (C) and Tadehagi sp. (T23).

The Relationship ◽

Eleven Species

Forage legumes are a potentially important source of dietary energy and protein for ruminants in the tropics. However, the nutritive value of such legumes can be depressed by their polyphenolic content. The effects of these compounds include inhibition of fermentation in the rumen and complexing with enzymes, dietary protein and fibre.The aim of this study was to evaluate the relationship between the total polyphenolic (TP), total condensed tannin (TCT), bound condensed tannin (BCT) and soluble condensed tannin (SCT) contents of forage legumes and their fermentability in vitro.Leaf samples from eleven species of tropical forage legume were collected from Colombia (six species) and Ethiopia (five species). Lyophilised, milled samples of each of the eleven species (1 g x 5 replicates) were placed in gas-tight culture bottles containing an anaerobic medium inoculated with bovine rumen fluid. The cultures were incubated under anaerobic conditions for a total of 7 d h at 39°C.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.
