INTISARIAsap cair merupakan bahan yang bermanfaat untuk digunakan dalam proses pengawetan telur. Tujuan penelitian ini adalah untuk mengetahui pengaruh penggunaan abu pelepah sawit dan asap cair dalam proses pengasinan terhadap kuaitas fisik telur itik pegagan. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) pola searah yang terdiri atas 5 perlakuan dan 4 ulangan dengan setiap ulangan terdiri 5 butir. Perbedaan mean diuji dengan Duncan Multiple Ranges Test. Perlakuan terdiri atas R0, R1, R2, R3, dan R4, di mana seluruhnya menggunakan abu pelepah kelapa sawit dan garam dapur (1:0,25) serta masing-masing ditambahkan larutan asap cair secara berurutan 0% (kontrol), 2,5%, 5%, 7,5%, dan 10% (v/v). Variabel yang diamati adalah kualitas fisik telur asin, meliputi susut bobot telur, berat kuning telur, berat putih telur, indeks kuning telur, indeks putih telur, berat kerabang telur, tebal kerabang telur, kedalaman rongga udara, warna kuning telur, pH kuning telur, pH putih telur, haugh unit (HU), viskositas putih telur. Hasil penelitian menunjukkan bahwa penggunaan abu pelepah kelapa sawit dan asap cair dalam proses pengasinan berpengaruh nyata (P<0,05) terhadap tebal kerabang telur, kedalaman rongga udara, berat putih telur, berat kerabang telur, pH putih telur, indeks putih telur, haugh unit (HU), viskositas putih telur, dan susut bobot telur, akan tetapi berpengaruh tidak nyata (P>0.05) terhadap warna kuning telur, pH kuning telur, berat kuning telur, dan indeks kuning telur. Kesimpulan penelitian adalah penggunaan abu pelepah kelapa sawit dan asap cair dalam proses pengasinan dapat mempertahankan kualitas fisik telur asin itik pegagan.(Kata kunci: Abu pelepah kelapa sawit, Asap cair, Kualitas fisik, Telur itik pegagan) R0, R1, R2, R3, and R4, where all of treatments used palm oil fronds ash and salt (1:0.25) and each treatment was added liquid smoke 0% (control), 2,5%, 5,0%, 7,5%, and 10% (v/v) ABSTRACT Liquid smoke is a useful material for use in the process of preserving eggs. The purpose of this study was to determine the effect for use of palm oil fronds ash and liquid smoke in the process of salting to the physical quality of pegagan duck's egg. This study was assingned in a Completely Randomized Design, which consists of 5 treatments and 4 replications. Each replicatation used as much as 5 eggs. The treatment consists of

Liquid smoke is one of the feed additive that can be given to animals. The aim of the study was to determine the influence of liquid smoke given through drinking water on meat quality and production of fecal ammonia in broiler. Variables observed were meat pH, water holding capacity, cooking loss, the tensile strength of meat, cut off strength of meat, blood urea nitrogen and creatinine concentrations, and fecal ammonia. The experiment was assigned in a completely randomized design with 5 treatments, and 4 equal replicates. The treatments tested were symbolized as R0, R1, R2, R3, and R4, based on the level of liquid smoke added into drinking water (v/v) namely, 0%, 0.25%, 0.50%, 0.75%, and 1.00%, respectively. The data were subjected to analysis of variance, and continued to Duncan's multiple range test to determine the difference between treatment mean values at 5% probability. The results indicated that addition of liquid smoke up to 1% did not affect the meat pH, water holding capacity, cooking loss, the tensile strength of meat, blood urea nitrogen, and creatinine content, but it decreased the cut off strength of meat and fecal ammonia. It was concluded that an optimal dose of granting liquid smoke through drinking water was 1%.

Data on the evolution of blood metabolites and metabolic markers in neonatal piglets are scarce, although this information is vital to detect physiological aberrations from normal development. We aimed to characterize age- and nutrition-related changes in the plasma metabolome and serum biochemistry of suckling and newly weaned piglets and assess metabolite patterns as physiological markers for the two phases. In two replicate batches (n = 10 litters/group), piglets either received sow milk alone or were additionally offered creep feed from day 10 until weaning (day 28). Blood was collected from one piglet/litter on days 7, 14, 21, 28, 31 and 35 of life, totaling five females and five males/group/day. Signature feature ranking identified plasma triglycerides (TG) as discriminative for age and nutrition during the suckling phase. Influential TG 20:4_36:5, TG 17:0_34:2 and TG 18:2_38:6 were higher in creep-fed piglets on days 14, 21 and 28 of life, respectively, compared to only sow milk-fed piglets. Metabolites belonging to pathways within histidine, D-glutamine and D-glutamate metabolism as well as hippuric acid were distinctive for the postweaning compared to the suckling period. In conclusion, plasma lipid profiles especially corresponded to the type of nutrition in the suckling phase and showed a strong weaning effect.
