Esta pesquisa teve por objetivo investigar as propriedades químicas e cômputo químico dos aminoácidos da farinha e de concentrado protéico de feijão guandu (Cajanus cajan (L.) Millsp). A farinha apresentou composição química adequada em relação a outras leguminosas. O procedimento de extração aquosa de proteína, a partir de grãos de feijão guandu com 25,73% de proteína, permitiu a obtenção de concentrado protéico com 52,47% de proteína, em base seca, compreendendo concentração da ordem de 103,85%. O concentrado protéico de feijão guandu apresentou composição química adequada, sendo que cinzas e açúcares solúveis foram concentrados 122,17 e 21,86%, respectivamente, em relação ao grão. Os níveis de aminoácidos no concentrado protéico foram similares aos de farinha de guandu, porém, a metionina foi concentrada em 42,64%. O cômputo químico indicou que os aminoácidos limitantes primários na farinha e concentrado protéico foram os sulfurados totais. A composição química da farinha e do concentrado protéico de guandu indicou potencialidade para utilização de ambos como componentes de alimentos para seres humanos e animais. Abstract The aim of this work was the investigation of the chemical properties of Pigeon pea (Cajanus cajan) (L.) Millsp) flour and protein concentrate. The flour presented suitable chemical composition in comparison to other legumes. The water extraction procedure of protein, from Pigeon pea grains with 25,73% of protein allowed to obtain a protein concentrate with 52,47% of protein in dry basis, resulting an increase in order of 103,85%. The protein concentrate of Pigeon pea showed suitable chemical composition, having an increase of 122,17% in ashes and 21,86 % in soluble sugars in relation to the crude grain. The amino acids levels in the concentrate were similar to those in the flour, however there were an increase of 42,64% in methionine concentration. The chemical score suggest that the primary limiting amino acids in the flour and in the concentrate were the total sulphur amino acids. The chemical composition of the flour and concentrate of Pigeon pea showed perspectives of its utilization as feed components for humans and animals.

This study was divided into three parts. The first evaluated the effects of five stages of plant maturity (60, 75, 90,120 and 180 d) on the agronomic characteristics, chemical composition and in vitro degradability (IVDMD) of pigeon pea [Cajanus cajan (L.) Millsp.] 'Kaki' and its anatomical fractions, leaves and stems. In the second part, the selective consumption of this legume was studied. In the third part, the effects of the inclusion of pigeon pea in diets based on tropical grass hay for goats on voluntary intake, and digestibility of dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) were determined. Plant height increased and leaf :stem ratio decreased, as the plants grew. In the whole plant, DM and NDF content increased (P < 0.05) by 13.9 and 19.2 percentage units, but CP content numerically decreased by 4.8 units as plant maturity progressed from 60 to 120 d. At the five successive stages evaluated, CP content in the leaves exceeded that of the stems, whereas NDF content showed the opposite trend. The IVDMD values were 69.6% in the whole plant, 73.9% in the leaves, and 50.4% in the stems. Whole plant IVDMD decreased (P < 0.05), with advancing plant maturity, from 71.2% at 60 d to 55.8% at 180 d. In the selective consumption trial, intake of fresh pigeon pea was compared with that of fresh native tropical grass (NTG) or NTG hay. A high selection of pigeon pea was observed for the first 10 minutes, but during the following 20 minutes this selection decreased. In the voluntary intake and digestibility trial that utilized six goats (26.4 kg live weight) to evaluate the inclusion of 25% of pigeon pea in a NTG-based diet, CP intake was markedly higher (P < 0.05) with legume supplementation. Dietary inclusion of the legume also tended to improve the digestibility of DM and CP but not at the P < 0.05 level of significance (56.7% vs. 51.4% and 58.7 vs. 51.2%); however, it did not affect NDF digestibility. As the pigeon pea plant increased in height, changes occurred in leafistem proportions and chemical composition. The IVDMD results suggest that the interval from 75 to 120 d of growth is favorable for possible utilization of pigeon pea as fresh forage in diets for small ruminants.

Cutting Regimes

AbstractThis study evaluated the effect of cutting regime on biomass yield and nutrient composition of pigeon pea (Cajanus cajan (L) Millsp.) fodder in the Guinea Savanna Agro-Ecological Zone of Ghana. Three cutting regimes (12, 16 and 20 Week After Planting [WAP]) in RCBD were imposed on Cajanus cajan at both initial establishment and regrowth. At each harvest, biomass yield was estimated after which samples of the fodder were separated into leaf and stem botanical fractions for chemical composition and in vitro digestibility. Cutting regime significantly affected plant height, number of branches and stem diameter in both the initial establishment and regrowth. Biomass yield was significantly affected by cutting regime in the initial establishment but not the regrowth. The biomass yield was highest in the harvest at 20WAP (6515kgDM/ha) while 12WAP (3175 kg/ha) recorded the lowest biomass yield in the initial establishment. All chemical composition parameters were significantly affected by cutting regime and botanical fractions except hemicellulose in the initial establishment. Cutting regime also significantly affected DM, CP and ash concentrations in the regrowth with botanical fraction significantly (P < 0.05) influencing CP, NDF, ADF and ash. The highest CP was obtained in the leaf fraction harvested at 12 WAP and 20 WAP in the initial establishment and regrowth respectively. Cutting regime, botanical fraction and their interaction were significant in gas produced at 24 h, SCFA and ME in both the initial establishment and regrowth stages. In conclusion, harvest at 20WAP produced the highest biomass yield but lower CP in the initial establishment whiles in the regrowth, harvest at 20WAP produced higher biomass yield, CP and ME.
