Formulation and Evaluation of Milk Replacer on Performance of Local Twin Lambs Before and After Weaning

Abstract

The objective of this experiment was to evaluated the effect of milk replacer on performance of local twin lambs before weaning and up to one month after weaning. Three pairs of local twin lambs aged about 2 weeks, weighed 3.83±0.4 kg were used and divided into three groups consisted of three animals in each group. The lambs were allocated in a randomized block design. The treatment diets were P1: milk source from mother milk and P2: milk source from milk replacer. Data were analyzed using descriptive analysis for dry matter, gross energy and protein intake before weaning and feed convertion ratio before weaning , and the other variable were analyzed using analysis of variance. The results showed that the treatments did significantly affect (P<0.05) dry matter, and gross energy intakes after weaning, daily weight gain before and after weaning, and weaning weights from mother milk and milk replacer. However those treatments did not significantly affect (P>0.05) feed conversion ratio, and 90 days weight. All lambs were health and there were no mortality, but performance of lambs given mother milk were better than given milk replacer.

Penelitian ini bertujuan untuk mengevaluasi milk replacer dengan melihat pengaruh pemberian milk replacer tersebut terhadap performa anak domba kembar dua umur dua minggu sampai lepas sapih dan mengevaluasi performa anak domba setelah disapih dengan pemberian pakan komersial yang sama. Domba yang digunakan terdiri dari 3 pasang anak domba kembar dua umur dua minggu hasil persilangan domba lokal ekor tipis dan domba Garut yang berasal dari 3 induk dengan rata-rata bobot badan 3,83±0,4kg. Rancangan percobaan yang digunakan pada penelitian ini adalah Rancangan Acak Kelompok dengan pengelompokan berdasarkan waktu lahir anak yang terdiri dari dua perlakuan dan tiga ulangan pada masing-masing perlakuan. Perlakuan terdiri dari : P1 (anak mengkonsumsi susu induk); P2 (anak mengkonsumsi milk replacer). Peubah yang diamati adalah konsumsi pakan, pertambahan bobot badan harian pra dan pasca sapih, bobot sapih, bobot satu bulan pasca sapih, konversi pakan, mortalitas dan kesehatan ternak. Data yang diperoleh akan dianalisis menggunakan statistika deskriptif untuk peubah konsumsi pakan pra sapih, konversi pakan pra sapih, mortalitas dan kesehatan ternak, sedangkan data peubah lainnya akan dianalisis menggunakan Sidik Ragam (ANOVA).
