Formulasi Susu Pengganti dan Evaluasi Pengaruhnya terhadap Performa Anak Domba Kembar

Abstract

The purpose of this experiment was to formulate and evaluate milk replacer on the production performance of twin lambs from before weaning to one month after weaning. Three pairs of twin lambs aged two weeks with a body weight of 3.83 ± 0.4 kg were divided into two groups, each consisting of three lambs. The treatments applied were PSI = lamb given mother's milk and PMR = lamb given milk replacer. Pre-weaning dry matter consumption data were analyzed descriptively and other data were analyzed using the T-test. The results showed that the dry matter consumption lambs that were given milk replacers in pre-weaning was 164.18 ± 31.25 g/head/day with the largest proportion coming from milk replacers (61.4%). PSI group lambs had dry matter and energy consumption after weaning, daily gain before and after weaning, and body weight when weaned were significantly higher (P <0.05) than the PMR group lambs. However, the ratio of feed conversion and body weight at 90 days in the two groups of lamb were not significantly different. All lambs were healthy and no one died. It is concluded that formulated milk replacer provides production performance in lambs that are equivalent to lambs fed with mother's milk. ABSTRAKTujuan dari percobaan ini adalah untuk memformulasi dan mengevaluasi susu pengganti (milk replacer) terhadap kinerja produksi anak domba kembar dari sebelum disapih hingga satu bulan setelah disapih. Tiga pasang anak domba kembar berumur dua minggu dengan bobot badan 3,83± 0,4 kg dibagi menjadi dua kelompok yang masing-masing terdiri dari tiga ternak. Perlakuan yang diterapkan adalah PSI = anak domba yang diberi susu induk dan PMR = anak domba yang diberi milk replacer. Data konsumsi pakan pra sapih dianalisis secara deskriptif dan data yang lain dianalisis dengan menggunakan uji-T. Hasil penelitian menunjukkan bahwa konsumsi BK anak domba yang diberi milk replacer pada pra sapih adalah sebesar 164,18 ± 31,25 g/ekor/hari dengan proporsi terbesar berasal dari milk replacer (61,4%). Anak domba kelompok PSI memiliki konsumsi bahan kering dan energi setelah disapih, pertambahan bobot badan harian sebelum dan setelah disapih, dan bobot badan saat disapih nyata lebih tinggi (P<0,05) daripada anak domba kelompok PMR. Namun, rasio konversi pakan dan bobot badan umur 90 hari kedua kelompok anak domba tidak berbeda nyata. Semua anak domba sehat dan tidak ada kematian. Disimpulkan bahwa susu pengganti yang diformulasi memberikan kinerja produksi pada anak domba yang setara dengan anak domba yang diberi air susu induk.Kata kunci: susu pengganti, susu induk, kinerja produksi, anak domba kembar

Importance of Colostrum for Calf Health and development: A brief review

“…Colostrum is a perfect food source for newborn calves, however, there is something that needs careful attention because giving Colostrum at low quality can lead to health problems for calves who consume it sooner after their birth. However, in a forced situation, if Colostrum cannot be obtained, milk replacer can be used whose quality is not much different from highquality Colostrum from the parent (Sudarman et al, 2019). According to Walz et al (1997) and Godden et al (2019), one of the earliest potential exposures for calves is to infectious agents such as Mycoplasma spp, Mycobacterium avium subspecies paratuberculosis and Salmonella spp.…”
