Abstract/ Executive Summary:

The effect of supplementation of Jackfruit (Artocarpus heterophyllus) tree leaves and mashkalai (Vigna mungo) bam on the intake and digestibility of freshly cut common grass by Black Bengal goats was evaluated. Twelve castrated goats of approximately 5-6 months age were randomly allocated to three dietary treatments: freshly cut common grass ad libitum, common grass+lOOg Jackfruit tree leaves and common grass+lOOg mashkalai bran. Although digestibilities of dry matter, organic matter, nitrogen and neutral detergent fibre were very similar in the grass alone and mashkalai bran supplemented goats but the values were significantly (p < 0.01) higher than those observed in the Jackfruit leaves supplemented goats. Supplementation of mashkalai bran promoted higher (p < 0.05) digestible nutrients intake with the consequent higher daily live weight gain (75 g) than those fed grass alone (31 g) or supplemented with Jackfruit tree leaves (30 g). It could be concluded that mashkalai bran could be a suitable supplement for goats consuming common grass in the tropics and subtropics.

Objectives:

It is therefore, essential to investigate the effect of feeding goats with common grasses and also when supplemented with tree leaves or cereal by-products on intake digestibility and body weight gain.

Methodology:

Twelve castrated Black Bengal goats of approximately 5-6 months age with and average body weight of 11 kg were used as experimental animals. These animals were purchased from the local market, were dewormed and divided randomly into three groups A, B, and C of four goats each. The animals were kept in individual pens made of bamboo slated floor throughout the trial period. Feeds and feeding Three groups of animals were randomly allocated to three experimental diets i.e., common grass, common grass + 100g Jackfruit tree leaves and common grass + 100g mashkalai bran. Fresh jackfruit tree leaves were collected daily in the morning. Animals were given mashkalai bran followed by feeding freshly cut common grass. In all treatments, common grass was supplied ad libitum (at the rate of 120% of the fresh intake of previous day) twice daily, half in the morning (7:00 h) and the rest in the afternoon (16:00). Refiisals of common grass were collected every morning. The animals had free access to freshwater. The feeding trials were continued for 60 days after the initial 15 days adjustment period. Digestibility trial Two digestibility trials were conducted during the 3rd and 6th weeks of feeding trials according to the methods described by Swift et al. (1950). During digestibility trials feed offered, feed refused, faeces voided were recorded daily. Growth measurements The animals were weighed at weekly intervals during the whole experimental period. The animals were weighed in the morning before feeding. Chemical and statistical analysis The samples of feeds, refusals and faeces were analyzed for dry matter (DM), organic matter (OM), nitrogen (N) according to the methods of AOAC (1975). Neutral detergent fibre (NDF) was determined after Georging and Van Soest (1970). All the data were analyzed by statistical method using analysis of variance (Steel and Torrie, 1980) in completely randomized design (CRD) and mean values were tested for differences between treatments with Duncan's New Multiple Range Test (DMRT) using Statistical Analysis System (SAS, 1982).

Achievement/Findings:

Based on above findings, it can be concluded that mashkalai bran could be a potential supplement for goat while feeding grasses. How mashkalai bran improved the growth rate of goats when fed green grass, deserve further investigation.
