Abstract/ Executive Summary:

Study was undertaken with the objective to determine the effect of replacing conventional concentrate with dried moringa foliage on the performances of growing native sheep. A total of thirty growing native sheep of 3 to 6 months of age were randomly allocated to five groups having six lamb per treatment. A control diet containing 30% molasses mixed rice straw and 70%concentrate mixture was fed to a group of sheep. The concentrate was replaced with moringa on DM basis. Thus, five dietary treatments consisted of varying proportion of moringa foliage (MF) and concentrate (C), were T₁(100MF); T₂ (75MF:25C); T₃ (50MF:50C); T₄ (25MF: 75C) and T₅ (100C). The experiment was arranged in a completely randomized design (CRD).The duration of feeding and growth trial was 93 days. After completing the feeding trial, digestibility trial was carried out for 7 days. Four animals from each treatment were randomly selected to slaughter for evaluating the carcass quality.

Objectives:

To determine the effect of replacing conventional concentrate with dried moringa foliage on the performances of growing native sheep.

Methodology:

A total of thirty growing native sheep of 3 to 6 months of age were randomly allocated to five groups having six lamb per treatment. A control diet containing 30% molasses mixed rice straw (2.5% molasses) and 70%concentrate mixture of broken maize-42%, soybean meal-38%, wheat bran-17%, vitamin-1%, DCP-1% and salt-1% was fed to a group of sheep. The concentrate was replaced with moringa foliage (moringa foliage-97%, vitamin-1%, DCP-1% and salt-1%) at 25, 50, 75 or 100% on DM basis. Thus, five dietary treatments consisted of varying proportion of moringa foliage (MF) and concentrate (C), were T₁(100MF); T₂ (75MF:25C); T₃ (50MF:50C); T₄(25MF: 75C) and T₅ (100C). The experiment was arranged in a completely randomized design (CRD).The duration of feeding and growth trial was 93 days. After completing the feeding trial, digestibility trial was carried out for 7 days. Four animals from each treatment were randomly selected to slaughter for evaluating the carcass quality.

Achievement/Findings:

Average total DM intake was significantly higher in T₅(939.0 g d^-1) and T₂ (885.5 g d^-1) than T₁ (830.0 g d^-1), T₃(826.3 g d^-1), T₄ (823.3 g d^-1) while there was no significant difference in case of DM intake in percent live weight (3.96 to 4.11%). DM (75.30 to 79.98%), CP (79.20 to 81.74%) and OM (78.63 to 80.07%) digestibility was not significant different among the treatments. However, ADF and NDF digestibility were linearly (r=0.97; r=0.87 respectively) increased with an increasing level of moringa foliage in the diet. FCR, dressing percent did not vary significantly (P>0.05).The percentage of lean meat of warm carcass weight was significantly higher in T_2. Similarly, lean: fat increased linearly (r= 0.97) with the increasing level of Moringa foliage in the diet. However, carcass fat and waste fat percentage linearly (r=0.96; r=0.97 respectively) increased with the increasing of concentrate mixture. The result revealed that decreasing the level of concentrate mixture with Moringa foliage in the diet of growing sheep may shows desirable leaner carcass with a higher proportion of lean meat and lower weight of fat to improve carcass characteristics. Thus, moringa foliage may replace conventional concentrate partially or entirely in a straw based diet of sheep.
