“…The chemical composition of CA (Tables 1 and 2) in general agreed with the earlier findings of Donkoh et al 8, 9 and other reports on CC,4, 5, 10, 11, 13 although CP was lower and OA was higher in the present study as compared with Donkoh et al 8, 9 The higher amounts of OA found at 4 and 8 weeks of regrowth could be explained in terms of a response to cutting, which may lead to new growth containing higher amounts of antinutrients than uncut leaves as a response to the effects of browsing 21…”

“…In the plant kingdom, when OA is present in a species, then more often than not HCN is also to be found 28. This axiom has been shown to hold true for chaya in both this study and previous reports 8, 9. Liener 30 has stated that 2.0–3.0 g HCN kg −1 DM is likely to cause intoxication in humans.…”

“…Both CC and CA are important sources of protein, carotene, B vitamins, ascorbic acid, calcium and iron,4–11 and the amino acid availability in chickens has been reported as 0.84 by Donkoh et al 8 They also contain glucosides of hydrocyanic acid, 3, 6, 8, 9, 12, 13 which are destroyed by exposure to heat, from 1.02 to 1.98 g kg −1 DM, and from 0.088 to 0.099 g kg −1 DM in fresh and dried leaves respectively, and oxalate ranging from 0.85 to 1.07 g kg −1 8, 9…”

The chemical composition of chaya (Cnidoscolus spp) leaves, as a promissory edible tropical shrub for both humans and animals was evaluated. The chemical composition of C aconitifolius did not differ significantly with age of regrowth, with the exception of ether extractives and the oxalic acid content. Galactose, glucose and xylose were the most important sugars found in the insoluble fraction and, galactose and uronic acid were the main components in the soluble portion of non-starch polysaccharides (NSP). There was a total content of 197.2 g kg −1 NSP, of which 68.72 and 31.26% corresponded to the insoluble and soluble components respectively. The amino acid composition of C aconitifolius ranged from 0.416 for lysine to 0.641 for valine relative to their contents in soyabean meal. Nevertheless, without exception, the concentrations of all the essential amino acids in C aconitifolius were higher than the corresponding values in alfalfa, a fibrous foodstuff widely acceptable in diets for farm animals.

“…Dietary inclusion of 20-60kg Mimosa invisa leaf meal (MLM) in cockerel finishers, broiler starters and finishers resulted to depressed weight gain and feed conversion ratio which were significant (P<0.05) and progressive. Poor performance of these birds is attributed to the presence of mimosine in the MLM [44], low acceptability [36] and poor digestibility [8].…”

[8]recommended 25g Cindoscolusaconitifolius leaf meal per kilogramme of feed for optimal chickens performances, while [25], [29] concluded that 25gMLM/kg feed was adequate for broiler chicks and finisher maximum performance.…”

Aims:The objective of this study was to access the growth responses of chickens fed different leaf meal supplements. Study Design: The experimental design used was completely randomized design for the chicks and completely randomized block design for the growing pullets and cockerels. Place and Duration of Study:The experiments were carried out at Bora Poultry Unit of Federal College of Animal Health and Production Technology, Institute of Agricultural Research and Training (IAR&T) Ibadan, Nigeria. The experiments were carried out between the years 2004 to 2009. Methodology: Nutritive potentials of Centrosema pubescens, Mimosa invisa and Pueraria phaseoloides leaf meals (LM) were determined and evaluated using different types of chicken within the years 2004-2009. The diets were formulated to contain 0,20/25, 30/40, 60/75 and 80/90g LM/kg feed and 120 to 150 birds were used in each experiment. Each treatment was replicated three times. All ingredients in each experiment were of constant Research ArticleAmerican Journal of Experimental Agriculture, 3(3): 506-519, 2013 507 weight, except the soybean and groundnut cake which test ingredients replaced some percentages weight for weight. Data on feed intake and weight gain were subjected to oneway ANOVA and comparisons were made using Duncan's Multiple Range Test. Results: Results revealed that the LM are rich in crude protein (21.36-23.34%) and ash (4.25 -9.14%). The most available mineral elements were potassium (0.45-1.85%) and calcium (0.60 -1.726%). The concentration of tannin was highest in the LM (1.57-3.35g/100gDM) unlike oxalate (0.037-0.065g/100gDM). The poorest LM in terms of nutritive value and chicken performance was Mimosa invisa leaf meal (MLM), while the best was Centrosema pubescens leaf meal (CLM). Inclusion of 40 -60gCLM/kg feed for Black Nera chicks and finisher pullets and 75gCLM/kg feed for broiler starters and finishers resulted to significant (P<0.05) reduction in feed intake and weight gain. Feed intake and weight gain of broiler starters and finishers and cockerel growers fed 20 -60gMLM/kg feed supplements significantly (P<0.05) and progressively decreased with increased dietary concentration of MLM supplement. Broiler starters and finishers fed 30-90PLM/kg feed had increased feed intake, which was progressive, unlike their weight gain which depressed significantly (P<0.05) with increased concentration of Pueraria phaseoloids leaf meal (PLM). Conclusion: Hence, 20 and 25g CLM/kg feed is recommended for pullet chicks/growing pullets and broiler chicken, respectively, while PLM and MLM are not recommended, for chicken nutrition due to depression in growth rate.

Chaya (Cnidoscolus aconitifolius ssp. aconitifolius Breckon) is a fastgrowing, semi-perennial, and semi-woody Mesoamerican euphorbiaceous. It is used as a leafy green vegetable and prevailingly cropped in tropical savanna climate. However, cropping of chaya is possible in both dryer and more humid climates. Although the crop has its origin in the Maya region of Southeast Mexico, Guatemala, and Belize, chaya is popular throughout Mesoamerica. Due to its high nutritional value, cooked chaya leaves are an essential ingredient of the diet of Maya communities, especially in Southeast Mexico. Chaya is also used as an ornamental plant, for forage, and in traditional Maya medicine, where it is used to cure a wide range of diseases such as diabetes, kidney problems, arteriosclerosis, gallstones, and high cholesterol. Chaya can be called a semi-domesticated plant: Apart from wild chaya, there are four chaya varieties, whose grade of domestication varies from cropped almost wild phenotypes to entirely domesticated: 'Chayamansa,' 'Redonda,' 'Estrella,' and 'Picuda.'
