Abstract/ Executive Summary:

The study was undertaken to find out the chemical composition of different vegetable peels available in Rangunia, Chittagong, Bangladesh. Total 10 different vegetable peels i.e., Banana blossom (Musa sapientum), Bottle gourd peel (Lagenaria siceraria), Brinjal peel (Solanum melongena), Gram husk (Cicer arietinum), Green banana peel (Musa sapieutum), Green coconut peel (Cocos nucifera), Pea husk (Pisum sativum), Potato peel (Solanum tuberosum), Pumpkin peel (Cucurbita maxima), Ripe banana peel (Musa sapientum) were collected from the study areas. Samples were collected, chopped and tested immediately for moisture content and remaining samples were sun-dried and processed using standard procedure. Chemical analyses of the samples were carried out in triplicate for Dry matter (DM), Crude protein (CP), Crude fiber (CF), Nitrogen free extracts (NFE), Ether extracts (EE) and Ash. Results indicated that, crude protein content in Banana blossom was 13.8 g/100g, Bottle gourd peel 7.0 g/100g, Brinjal peel 12.3 g/100g, Gram husk 4.5 g/100g, Green banana peel 7.0 g/100g, green coconut peel 4.9 g/100g, pea husk 6.2 g/100g, Potato peel 13 g/100g, Pumpkin peel 16.5 g/100g and Ripe banana peel 6.8g/100g. In addition to crude protein, all samples contained a substantial amount of crude fiber, nitrogen-free extracts, ether extracts and ash. It could therefore be inferred that, the vegetable peels might be an alternative to conventional feeds for livestock of the developing countries.

Objectives:

Recently, there has been increasing recognition of the use of shrub and tree fodder as livestock feed (Saadullah, 1989). Therefore, the current study was undertaken to find out the chemical composition of different types of vegetable peels that could be used as potential unconventional feeds for livestock.

Methodology:

Study area Rangunia is a sub-district of Chittagong. There are lots of small and large dairy farms in Rangunia. Small dairy farm owner mostly practicing the use of unconventional feed particularly vegetable peels. Therefore, Rangunia was selected as the study area for collection of sample.

Collection of sample Samples were collected by using simple random sampling technique. Total 10 different types of unconventional feeds were selected randomly. Approximately 2000 grams of each sample was collected. Samples were wrapped up by polythene bag and preserved in the laboratory for chemical analysis.

Preparation of sample Fresh samples were cut into the smaller pieces of 1 cm sieve size and placed into the hot air oven for proper drying. The dried samples were subjected to grinding to make it homogenous powder. Later on, it was mixed properly and exposed to shade to cool down for sampling. Individual samples were kept in air tight polythene bag and identified by marker. Later on it was subjected to chemical analyses.

Analysis of sample Chemical analyses of the samples were carried out in triplicate for moisture, DM, CP, CF, NFE, EE and ash in the animal nutrition laboratory and PRTC laboratory in Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh as per AOAC (2006).

Calculation of ME Metabolizable energy (ME) was calculated separately for all 10 different samples. Calculation was performed by using the mathematical formula as per Lodhi et al. (1976).

Statistical analysis Data related to chemical composition of unconventional feeds were compiled by using Microsoft Excel 2007. Chi-square (χ²) test was performed to analyze the data by using SPSS 16.0. Statistical significance was accepted at 5 % level (P<0.05).

Achievement/Findings:

The year-round supply of sufficient feeds for livestock is the priority area for profitable livestock production. The available feedstuffs in Bangladesh are mainly crop residues, agro-industrial by-products and unconventional feed stuffs. The role of unconventional feeds in ruminant nutrition continues to increase. The utilization of unconventional feeds will not only benefit the milk and beef industry but also increase the economic return. The unconventional feed can also be used during the scarcity of traditional feed.
