A 5 month long 2x2 factorial feeding trial was carried out to determine effects of crossbreeding and feed supplementation on meat productivity of goats in Laos. The indigenous goat breed (Lat) was used as the control to compare with the F1 (BT x L) as a result of crossbreeding Lat does with bucks of Bach Thao, an improved goat breed imported from Vietnam. For each genotype, 30 growing male goats at 7 months of age were chosen and equally divided into 2 groups, each being raised under either the traditional feeding regime (free grazing only) or an improved feeding regime including dried cassava hay and mineral block provided ad libitum in addition to the free grazing regime. Observations included feed intake, live weight gain, dressing percentage, body composition, carcass parts, and meat quality. This paper presents body composition and meat quality of the goats as affected by crossbreeding and feed supplementation. Results showed that although there existed significant differences in weight percentage of some organs (legs, lungs and liver) in the body, no significant diferences were observed for meat quality (tenderness, color, pH, drip loss and cooking loss) between Lat and F1 goats under the two different feeding regimes. It was therefore concluded that crossbreeding with Bach Thao bucks imported from Vietnam and feed supplementation (cassava hay and mineral block) well improved meat yield without negative effects on meat quality of goats in Laos.

【Objective】A 2×2 factorial trial was carried out to determine effects of genotype and nutrition on improved growth performance, carcass characteristics, and meat properties of goats in Laos. 【Method】The indigenous goat breed (Lat) was used as the control in comparison with F1 (BT×L) as a result of crossbreeding Lat does with Bach Thao bucks imported from Vietnam. For each genotype, 30 growing male goats at age of 7 months were chosen and equally divided into 2 groups, one was raised according to the traditional feeding regime (free ranging only) and the other with an improved feeding regime including cassava hay and mineral block provided ad libitum in addition to free ranging. The animals were observed for the average daily gain (ADG) and at the end, three animals per group were slaughtered to determine carcass characteristics (physical composition, primal cuts), and meat properties (shear force, color, pH, drip loss, and cooking loss). 【Result】The results showed that the ADG of F1(60.02 g/head/day) was very much higher (56.09%) than that of the indigenous goat (38.45 g/head/day). The ADG of goats supplemented with cassava hay and mineral block (55.45g/head/day)was also significantly higher (28.89%) than that of those not supplemented (43.02 g/head/day). No significant (P >0.05)effects of the crossbreeding and supplementation were found for dressing percentage and percentages of shoulder-foreleg, rump-rearleg, and breast-rip cuts in the carcass; however, the F1 had a bigger neck (P<0.01) but a smaller loin-abdomen cut (P<0.01) compared with the indigenous goat. No significant differences were observed for the parameters of meat characteristics between Lat and F1 goats under the two different feeding regimes. 【Conclusion】It was therefore concluded that crossbreeding with Bach Thao bucks and supplementation of cassava hay and mineral block improved meat yield without negative effects on meat quality of goats in Laos.
