Abstract

The pellets were produced from peanut straw (PTS), water spinach (WSP), Leucaena leucocephala leaves (LLL), Gliricidia sepium leaves (GSL), and Calliandra calothyrsus leaves (CCL). Each feedstuff was pelletized with the addition of 8% tapioca flour as a binder. The pellets were tested for chemical characteristics, physical appearance, and physical characteristics, which included the pellet length, density, stacking density, stacking compaction density, modulus of uniformity, modulus of fineness, pellet durability index (PDI), and water absorption. The data were analysed descriptively. The results of this research revealed that the nutritional composition of the pellets followed that of the raw feedstuff. All the pellets varied in color depending on the color of the raw material and had a medium texture. Each pellet had specific physical characteristics. The colors of PTS, LLL, GSL, and CCL were dark green, whereas WSP was dark brown. All single pellets had a medium texture, with PDI values above 97% and MF values greater than 4.1, which classified them into the coarse group. In terms of water absorption, the CCL had the longest absorption time, approximately 75.17 minutes, whereas the other pellets had absorption times less than 30 minutes. As a result, although a single feed ingredient can be produced as pellets, the physical and chemical qualities depend on the origin of the ingredient.

Abstract

The present study was aimed to investigate the effects of silo type for laboratory scale on chemical compositions, fermentation characteristics, and microbial counts of silage. Four typical silos use on a laboratory scale, consisting of transparent plastic bags (Silo A), black plastic bags (Silo B), transparent plastic bags covered with a bucket (Silo C), and transparent plastic bags covered with a sack (Silo D). All silo types were used to ensilage 5 kg Elephant grass (Pennisetum purpureum cv. Mott) for 21 d. Each Silo was conducted in triplicate. After ensiling, Silo C had higher crude protein with lower ammonia compared to other Silos (p<0.05). In addition, the Silo C resulted in lower pH, butyrate, and yeast with higher lactate and lactic acid bacteria (p<0.05) compared to other Silos. Silo C had the lowest bulginess, which indicated the optimum ensiling process. The present study concluded that ensiling forage with Silo C is more suitable and recommended for laboratory scale, which can reduce the errors, especially in the nutrient loss, production of ammonia, lactate, and butyrate, and also the counts of microbes in the silage.
