Feed Forage and Nutrition Value at Altitudes during the Dry Season in the West Java

Abstract

Field grass was a source of ruminant forage, especially for rural farmers in the West Java in different altitude. The aim of this study was to determine the potential of grass during the dry season which included the botanical composition analysis and chemical analysis of nutritional value. The study was conducted from September to November 2015. The method used was a survey method, sampling was multistage sampling. The parameters measured in the study included a botanical composition of the forage, biomass production of feed materials on fresh and dry matter, dry material content, an inorganic material included ash, calcium and phosphorus, protein, crude fiber, extract materials without nitrogen, and crude fat. The results showed that the areas in the West Java were drought in September and October, thus resulting in very limited supply of forage and the productivity of the forages was very low. A botanical composition in the highland area was more complete included grass, legumes and weeds than lowland areas and medium altitude. Forage production in highland areas was higher than in lowland areas and medium altitude. Feed plants in the lowlands had a greater fiber content which was forming energy for plants, and lower crude protein when compared to highland

The Genotype and Crop Age Effect on Nutritive Value of Corn Forage

“…In young plants (80 days) the NFE was significantly lower than old plants (100 days). According to Rochana et al (2016), NFE levels are strongly influenced by forage nutrient content.…”

“…The genotype advantage correlated with wide adaptation and growth strength in the rain fed conditions (Giridhar et al, 2016). Rochana et al (2016) states that crude protein is very important for the life and ruminants growth. Crude protein helps in breaking crude fibers derived from forage and providing amino acids for ruminants.…”

Production and nitrogen, phosphorus and calcium absorption of sword bean leaf (Canavalia gladiata) in application of rock phosphate and VAM inoculation

“…Legumes have a useful use in soil systems, plants, livestock and the atmosphere and are very effective with the proportion of 30-50% legume green against grass. According to Rochana et al (2016) legume plants are recommended as much as 30% of the total rations, Legume plants as a source of protein is one of the most important nutrients for the life and growth of ruminants. If the protein is sufficient for ruminants required in the process of decomposition of crude fiber forage, then the ruminants perform its functions to produce amino acids that are essential for the growth, reproduction and meet production of ruminants.…”

PENGARUH PEMUPUKAN NITROGEN TERHADAP PRODUKSI DAN KUALITAS HIJAUAN KACANG KORO PEDANG (Canavalia gladiata)

“…Fiksasi nitrogen simbiotik penting pada pertanian berkelanjutan untuk mengurangi penggunaan pupuk dan menjaga kelestarian lingkungan (Pamungkas dan Prasetya, 2017). Pada penelitian tanaman koro pedang memiliki kemampuan dalam memanfaatkan nitrogen di udara dengan fiksasi nitrogen yang dilakukan oleh bakteri rhizobium yang ditandai dengan nodul di akar (Indriani et al, 2019) Desember 2019 Safira, M.L., dkk./Jurnal Nutrisi Ternak Tropis dan Ilmu Pakan fungsinya dalam proses penguraian serat kasar yang berasal dari hijauan pakan sehingga tersedianya asam-asam amino bagi ternak tersebut (Rochana at al., 2016).…”

“…Sebaliknya jika ditambahkan pupuk urea maka kandungan serat kasar semakin menurun, hal tersebut dikarenakan peran nitrogen umumnya untuk pembentukan kandungan protein kasar. Hal tersebut sesuai dengan peenelitian Rochana et al (2016) bahwa kandungan serat kasar berbanding terbalik dengan kandungan protein kasar, hal tersebut dapat dilihat pada tanaman pakan di dataran rendah mendapatkan radiasi matahari penuh sehingga kandungan serat kasar lebih besar yang merupakan pembentuk energi bagi tanaman sedangkan kandungan protein kasar menurun.…”
