Forages for feeding dairy cows should conciliate the potential for high dry matter yield per unit area, maximizing animal stocking rate, with high nutritive value, which enables decreasing the amount of concentrate feedstuffs per milk unit produced. Eighteen sorghum cultivars were cultivated 0.70 m apart and with 12 plants per linear meter. Plants harvested at the milk-to-dough stage were ensiled in the laboratory. Eleven agronomic and chemical traits were evaluated. Silage samples were incubated in situ and the effective ruminal dry matter degradation (DEF) was calculated assuming a fractional passage rate of -0.04 h-1. Dry matter yield was 13.0 ± 2.3 (mean ± S.D.) t ha-1. The neutral detergent fiber content was 50.3 ± 3.8 and the DEF was 48.8 ± 2.8% (dry matter basis). The average sorghum DEF was 84% of the DEF of a composite sample of 60 corn hybrids simultaneously cultivated, ensiled and ruminally incubated. The 12 forage-type cultivars were taller, more productive, had higher fiber content and lower DEF than the 6 grain and dual purpose-type cultivars. The acid detergent fiber content had the greatest correlation with DEF (r= -0.64). The linear model correlating DEF with productivity was: DEF=54.694 - 0.4449 x t of dry matter ha-1 (r²=0.14). Although there are cultivars that show high productivity and digestibility, it seems to be difficult to conciliate the maximum nutritive value with the maximum productivity of the sorghum crop.

An experiment was conducted to evaluate the effect of growth, biomas yieds and nutritive value of Lablab purpureus, Centrosema pubescens and Mucuna pruriens under rain fed condition in Yola, Adamawa State, Nigeria. The field experiment was laid in a randomized complete block design with the plot divided into three main plots and replicated three times measuring 5x5m with inter and intra row spacings of 0.5m. The five harvesting stages are 6, 8, 10, 12 and 14 weeks, respectively. The growth in height increases with stage of growth and declined with reduction in rainfall. Higher growth were recorded in T3 (3.8 -354.8cm) followed by T2 (2.96-260.20cm) and then T1 (1.50-213.00cm) and the results were presented graphically. The result of the chemical composition of all the legumes showed that the crude protein decreases with stage of growth from weeks 6 -14 (14.40, 12.26, 10.65-10.08, 6.79, 6.49) and ADF and NDF (25.20, 32.15, 27.35-42.13, 40.33, 36.50 and 32.20, 54.45, 47.00- 51.24, 63.53, 66.33), respectively. The biomass yields were significantly different (P<0.05) for all the legumes at different harvesting stages T1 (2744.53-3186.93), T2 (2696.47- 3006.70) and T3 (2843.73-3147.63). It is therefore concluded that legumes could best be harvested between weeks 10 and 12 when the yield and quality are at levels to sustain the animals both for maintenance and production.

The influence of the improved drainage broadbed and furrow (BBF), as opposed to the traditional flat seedbed over the growing season on the dry matter yield and nutritive value of Avena sativa, Vigna unguiculata, Lablab purpureus, Vida dasycarpa, Trifolium steudneri and Sesbania sesban were studied on Vertisol. Up to 7 t/ha dry matter yield was recorded for Avena sativa and Lablab purpureus when planted on Vertisols with improved drainage. Dry matter yield of forage crops also increased with advance in stage of maturity or subsequent harvests. On both improved and traditional flat seedbed methods, the chemical analysis of forage crops showed similar declines in crude protein content and in vitro dry matter digestibility (IVDMD) levels as the maturity of forage crops progressed.

The experiment was conducted at screen house of Centre for Dry land Agriculture, Bayero University Kano, in the year 2016. The objective of the study was to determine the effects of poultry manure and nitrogen rates from battery cage and deep litter systems on dry matter yield, morphological characteristics and forage quality of Columbus grass (Sorghum almum). Sorghum almum seeds were sown in 32 plastic containers (dimensions 26 cm height, 28 cm top width and 20cm base width) perforated at the bottom containing 12 kg mixture of sandy and loamy soil in ratio of 1:3. The treatments consisted of poultry manure from two production systems (Battery cage and Deep litter) and nitrogen rates (50, 60, 70 and 80 kgN/ha) in a 2x4 factorial combined in a completely randomized design. Parameters measured were dry matter yield, number of tillers and stem diameter at the late boot stage of Sorghum almum, in addition, forage quality parameters (CP, ADF NDF, digestible dry matter (DDM) dry matter intake as a percentage of body weight (DMI) and relative feud value (RFV)) were also evaluated. The results revealed no significant (p>0.05) difference between battery cage and deep litter fertilized Sorghum almum but deep litter fertilized Sorghum almum had numerically higher dry matter yield (5062.30 kg/ha) than battery cage (4400.40 kg/ha) Number of tillers and stem diameter were found to be significantly greater (p<0.05) in Deep litter (2.56 and5.70mm respectively) compared to Battery cage (1.13 and 5.08mm respectively. Both dry matter yield and stem diameter of Sorghum almum were significantly (p<0.05) highest at 80 kg N/ha. Crude protein was observed to be significant (P<0.05) in Sorghum almum fertilized with poultry manure from deep liter (11.35%) compared with buttery cage (10.05 %). The CP value was observed to increase with increased nitrogen rate with the highest value recorded at 80 kg N/ha (1.71%). Dry matter intake (us a percentage of body weight) was equally greater (p<0.05) in Sorghum album fertilized with deep litter (2.63%) compared to battery cage (2.49%). The value for NDF was significantly higher in sorghum almum fertilized with battery cage, while that of ADF was greater in deep litter it can be concluded that, Sorghum almum fertilized with manure from deep litter system produced better yield and nutritive value.

SummaryThe dry matter yield, nutritive value and persistence of three legume species (Stylosanthes hamata Taub., S. capitata Vog. and Centrosema pascuorum Mart. ex. Benth.) cut at different frequencies during the growing season or only once at the end of the growing season were compared. The shorter cutting intervals enhanced regrowth, but very frequent cutting reduced total dry matter and seed yields. A defoliation interval of three to six weeks is recommended. Generally, S. hamata gave the best performance.Efecto del deshoje en tres legumbres
