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.

Planting Distance

The study sought to investigate the effect of two planting distances and Pigeon Pea (Cajanus cajan) intercrop on the biomass yield, chemical composition and in vitro organic matter digestibility (IVOMD) of Napier grass (Pennisetum purpureum). The treatments were laid in a 2x2 factorial RCBD. The factors were two planting distances (0.5x0.5 and 0.5x1m) and two levels of intercrop (Pigeon Pea intercrop and sole Napier grass). At 90-days, the grasses were harvested and biomass yield measured. The fodder was separated into leaves and stems for chemical and digestibility analysis in 2x2x2 factorial in CRD. The interaction at all levels was not significant for all the parameters. There was a significant main effect of planting distance, intercrop and botanical fraction on biomass yield, plant height, tiller number and fodder quality. Whilst biomass yield was higher (P=0.02) in the 0.5x0.5m, no significant difference was recorded in the effect of the intercrop. Whilst intercrop affected (P<0.05) IVOMD and ME, botanical fraction significantly affected DM, CP and ME. The leaf fraction had more (P<0.05) DM, CP and ME than the stem fraction. The study revealed that close planting distance enhanced biomass yield whilst Pigeon Pea intercrop and botanical fraction affected fodder quality of Napier grass.

Cookies were made from pigeon pea ( Cajanus cajan ) and cocoyam ( Xanthosoma sagittifolium ) flour blends. Pigeon pea flour (PPF) was mixed with cocoyam flour (CF) at ratios of 20:80, 30:70, 40:60, 50:50 and 60:40 respectively . The cookies were evaluated for proximate composition, saponins, oxalate, trypsin inhibitors, in -vitro protein digestibility, in -vitro carbohydrate digestibility, physical and sensory qualities. Standard experimental protocols were employed in the estimation of all indices. The protein content s of the cookies were significantly different (p<0.05) from each other and ranged from 10.89 to 11.60% with cookies from 60:40 PPF to CF having the highest value of 11.60% and cookies 20:80 PPF to CF having the least value of 10.89%. T he level s of antinutrients analyzed were low with saponin content ranging from 0.05 to 0.08mg/100g; trypsin inhibitors ranging from 0.08 to 0.11mg/100g and oxalate content between 0.06 to 0.68mg/100g. There were significant differences (p<0.05) observed in the in-vitro digestibility (protein and carbohydrate) with cookies made from 20:80 PPF to CF having the highest protein and carbohydrate in -vitro digestibilities of 64.81% and 67.35% , respectively. Results from the physical evaluation of the cookies revealed that the diameter and spread ratio of the cookies were significantly different (p<0.05) from each other and decreased with increasing levels of pigeon pea flour. Data obtained from the sensory evaluation indicated that the mean scores for taste, colour, general acceptabil ity and texture were generally high for cookies containing at least 50% cocoyam flour. However, cookies made from 20:80 PPF to CF had the highest mean scores for all the parameters assessed and were not significantly (p> 0.05) different from the control (100% wheat). It may, therefore be concluded from the strength of this work that cookies produced from 20% pigeon pea flour and 80% cocoyam flour have great potential as they compared favourably with cookies produced from wheat. The use of this composite flour would go a long way in reducing dependency on wheat flour in countries that import wheat.

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.
