Efek Temperature Humidity Index terhadap Konsumsi Air Minum dan Performans Ayam Kampung Super dengan Pemberian Enkapsulasi Fitobiotik Minyak Buah Merah

Ayam kampung super merupakan salah satu ayam kampung yang ditingkatkan performannya dengan perkawinan silang. Akan tetapi, perkawinan silang tidak serta merta memperbaiki performan. Ada beberapa hal lain yang mempengaruhi performan yaitu lingkungan dan feed additive. Oleh karena itu, tujuan dari penelitian ini adalah untuk mengetahui pengaruh Temperature Humidity Index dan pemberian enkapsulasi fitobiotik minyak buah merah terhadap konsumsi air minum dan performans ayam kampung super. Materi yang digunakan adalah alat ekstraksi, alat dan bahan enkapsulasi, buah merah, kandang individu dan ayam kampung super serta pakan starter. Metode penelitian yang digunakan yaitu Rancangan Acak Lengkap 5 perlakuan dan 4 ulangan dengan uji lanjut Duncan Multiple Range Test. Pemeliharaan dilakukan selama 56 hari dengan Temperature Humidity Index yaitu 24,44 - 35,21 oC. Hasil penelitian menunjukan bahwa penambahan enkapsulasi buah merah tidak berpengaruh terhadap konsumsi air minum (P>0,05), konsumsi pakan (P>0,05), feed conversion ratio (P>0,05) dan berpengaruh nyata terhadap pertambahan bobot badan (P<0,05). Berdasarkan hasil penelitian dapat disimpulkan bahwa kondisi lingkungan dilokasi penelitian (Papua) relatif ekstrim dilihat dari selisih THI. Selain itu, berdasarkan uji lanjut bahwa penambahan enkapsulasi fitobiotik minyak buah merah terhadap penambahan bobot badan menghasilkan perlakuan terbaik pada penambahan 2,5% enkapsulasi minyak buah merah.

Effect of forage Legetan (Synedrella nodiflora) fresh and hay on the physical quality of forage pellets

This study aimed to determine the effect of raw materials Legetan in the form of fresh and hay on the physical quality of pellets. Legetan (Synedrella nodiflora) was used as main ingredient, in the form of fresh and hay. The research method used a Randomized Completely Block Design (RCBD). Then, if there was a significant difference, it will be analyzed further using Duncan multiple range test (DMRT). The treatments consisted of P1 = 10% rice bran + 90% fresh Legetan; P2 = 20% rice bran + 80% fresh Legetan; P3 = 10% rice bran + 90% hay Legetan; P4 = 20% rice bran + 80% hay Legetan. The variables measured were rendement, color, texture, and price. The results showed that the utilization of Legetan forage as raw material, both hay and fresh with the proportions of rice bran either 10:90 or 20:80, had no significant effect on the physical quality of Legetan forage pellets. However, the higher the portions of Legetan forage in the forage pellets, the more affordable the pellet price will be.

Evaluation of some heavy metals bio-accumulation in meat and haemolymph of african landsnail (Archachatina Marginata Swainson)

The impact of captive rearing of snails (Archachatina marginata) on the bio-accumulation of some heavy metals (HMs) (Fe, Mn, Cu, Pb, Co, Ni, Cd and Cr) in the meat and haemolymph was evaluated in a two treatment trial (snails from the wild, (SW) and captive reared snails, (SC), each comprised of sixty snails of three replicates. Alldata collected (using standard analytical procedures) were subjected to ANOVA and significant means separated by Duncan Multiple Range Test. The trial revealed that the meat of SC had outstanding (P>0.05) Fe (22.30mg/kg) and Mn(4.79mg/kg), with no significant variation for DM, while the haemolymph recorded non-significant (P< 0.05) concentration for (Mn, Pb, Co, Ni, Cd and Cr). Its levels of Fe (3.50mg/kg) and Cu (2.06mg/kg) were however significantly (P>0.05) impacted by captive rearing. Generally the level of Cr in the meat and haemolymph were higher than 0.05mg/kg recommendation by WHO, hence snail meat and haemolymph must be consumed with caution and guidance.
