This paper aimed to evaluate the nutritive value and the quality of ensiled Napier grass (Pennisetum purpureum Schum) and banana (Musa acuminate) peelings.  Different levels of banana peeling and Napier grass were used in this study.  The levels of Napier grass and banana peeling compared as treatments with four replications were as follows: 100% Napier Grass (NG), 75% (NG) + 25% Banana Peeling (BP), 50%NG + 50%BP, 25%NG + 75% BP and 100%BP. Napier grass and banana peeling were mixed based on the percentage combination as treatments, weighed and placed into empty jam bottle with weights ranging from 64.4 grams to 509.2 grams as a simulated laboratory silo. Samples were stored in eight weeks at the Dairy Training Research Institute. Proximate analyses were done at Animal Nutrition Laboratory Institute of Animal Science while ADF, NDF, IVDMD, and IVOMD were done at the Animal Nutrition Division Laboratory at Dairy Training and Research Institute, UP Los Baños. Physically, the color of silage were light yellow with a  little greenish color for 100% napier grass, light to moderately yellow for the  three combinations of napier and banana peel and  yellow for 100% banana peel. Texture ranged from dry and coarse for napier grass, relatively dry for the combinations and moderately wet for the banana peel. The napier grass had a slightly acidic smell, the combinations had slightly sweet, acidic smell while the 100% banana peel had a sweeter, acidic smell.  Likewise, pH before ensiling had ranged from 5.7 (25%NG + 75%BP) to 7.5 ( 100% BP) while after  ensiling the pH changed from 4.575  ( 100% napier grass) to 5.75 ( 100% banana peel ). There were significant differences on DM, Moisture, CP, EE, CF, and Ash before ensiling. Similar trend was observed after ensiling except the ash content of all the treatments. ADF and NDF did not show significant variations in all treatments. IVDMD and IVOMD before ensiling varied significantly, but after ensiling only IVDMD of the treatments differed significantly. In terms of physical attributes, nutritive value and digestibility, banana peel can be used as silage material. All treatments generated comparable acceptability when fed to the animal.  It is suggested that further study, specifically in vivo trial, will be conducted to validate the feeding and nutritional value of banana peel as alternative silage for ruminants.

A 2×3 factorial experiment was conducted to compare two cultivars; Bangladesh Livestock Research Institute developed Napier hybrid-3 (BN-3) (Pennisetum purpureum) and Pakchong-1 (Pennisetum purpureum× P. glaucum) in terms of forage growth, biomass yield, and nutritional quality. Cultivars were cultivated in 03 blocks with 03 replicates and were harvested at 03 cutting periods (40, 50, and 60 days). Plot sizes for each cultivar were 25 m2 (5m × 5m), and in every plot, twenty-five stem cuttings with two healthy nodes per cutting were planted with (1×1) m spacing. The effects of cultivar and cutting period were significant on plant height, leaves per tiller, leaf DM production, and leaf stem ratio (LSR). Highest plant height (P<0.01) and leaves per tiller (P<0.05) were consistently produced by BN-3, while Pakchong-1 produced the highest amount of CP (P<0.05), LSR (P<0.05), tiller diameter (P<0.01) and diameter of the lowest node (P<0.01). Based on the %DM, DM yield, and CP yield, BN-3 performed better cutting at 50 days after the first plantation, but Pakchong-1 performed better cutting at 60 days after the first plantation. From the forage standpoint, Pakchong-1 seems to have little advantages over BN-3 because of its higher DM, LSR, and CP production. Bang. J. Anim. Sci. 2021. 50 (1):43-49

Varietal Differences

Feed supply in terms of quality and quantity plays an important role in livestock production and productivity. Here we report on varietal differences in yield and nutritional quality among 9 alfalfa accessions over 7 harvests following planting in Ethiopia. Experimental design was a randomized complete block with 3 replications at Chano Mille, Southern Ethiopia on a sandy loam soil where mean annual rainfall is 544 mm. Days to harvesting, plant height, dry matter yield, seed yield and the concentrations of the nutritional quality parameters crude protein (CP), neutral detergent fiber, acid detergent fiber, acid detergent lignin, hemicellulose and cellulose plus in vitro dry matter digestibility (IVDMD) and relative feed value (RFV) were assessed to rank the accessions. There were significant (P<0.001) differences between accessions and harvests in plant height, dry matter yield and seed yield. Accession ILRI_7323A performed best in all agro-morphological aspects. All accessions, except 1, produced forage with CP in excess of 30% and IVDMD greater than 80% with RFV greater than 150 at 50% flowering, indicating the high quality of forage produced. Further studies to assess the longevity of stands of the various accessions seem warranted along with studies in higher rainfall environments or under irrigation.

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.
