Abstract: The objective of this work was to evaluate the nutritional value silages from tall-sized and dwarf elephant grass (Pennisetum purpureum) genotypes, intercropped or not with butterfly pea (Clitoria ternatea). experiment performed in randomized complete blocks, a 4x2 factorial arrangement (four genotypes × two cropping systems). were: IRI-381 Elephant B, tall sized; Taiwan A-146 2.37 Mo...

The objectives of the present study were to examine relationships between methane (CH4) output and animal and dietary factors, and to use these relationships to develop prediction equations for CH4 emission from beef cattle. The dataset was obtained from 108 growing-to-finishing beef steers in five studies and CH4 production and energy metabolism data were measured in indirect respiration calor...

Greenhouse gas emissions from ruminant livestock production systems contribute significantly to the environmental footprint of agriculture. Emissions are lower for feedlot than grass-based primarily because extra time required grass-finished cattle reach slaughter weight. In contrast, legume forages greater quality grasses, which enhances intake and food conversion efficiencies, leading improve...

Five beef cattle management regimens were evaluated for their effect on meat quality, fatty acid composition, and overall palatability of the longis-simus dorsi (LD) muscle in Angus cross steers. A 98-d growing phase was conducted using grass silage with or without supplementation of growth promotants (Revalor G and Rumensin) or soybean meal. Dietary treatments in the finishing phase were devel...

The effects of high and medium feed value grass silage or maize silage (MS), each offered with a range of concentrate feed levels, and ad libitum concentrate on the performance of finishing lambs, which were either shorn or unshorn, were evaluated. Three silages were used: 1 medium feed value (MFV) and 1 high feed value (HFV) grass silage (DM digestibility [DMD] of 71.3% and 74.5%, respectively...

Abstrak. Hijauan merupakan pakan utama bagi ternak ruminansia, tetapi ketersediaan hijauan semakin berkurang. Limbah serai wangi limbah perkebunan yang mudah didapatkan serta efisiensi penggunaannya sebagai dapat ditingkatkan melalui proses amoniasi. Bungkil inti sawit menyumbang protein dalam ransum ruminansia sehingga dijadikan pengganti hijauan. Rancangan digunakan adalah rancangan bujur san...

Dairy cows fed on perennial-ryegrass pasture produce higher-quality milk in terms of fatty-acid composition; however, they produce much less milk compared to dairy cows under other systems. The low dry-matter intake (DMI) has been identified as the main factor responsible for the lower milk production in pasture-based systems. To maximize milk production from those systems it is important to ma...
