This study was carried out to investigate the possibilities of making silage from fruit juice industry waste.For this purpose, orange, lemon and tangerine pulp silage quality have been determined by comparing silage with maize and beet pulp silage.Treatment groups; 1) orange, 2) tangerine, 3) lemon, 4) maize and 5) sugar beet pulp. The silages were evaluated after 2 months from ensiling in the following areas: subjective evaluation, pH, dry matter, organic matter, crude protein, acid detergent fiber, neutral detergent fiber, ether extract and energy values (metabolizable energy) and net energy for lactation were calculated. As a result, it was determined that fruit juice industry residues were lower in terms of dry matter, but they contained higher energy due to their high organic matter content, digestibility and low cellulose content. In addition, it was determined that citrus pulp was evaluated as silage without any contribution.

This study was carried out to determine the effects of storage duration on nutrient composition and silage quality parameters. Corn was used as silage material. Corn (31.41% dry matter) was harvested at the dough stage and fermented for 90, 104, 118, 132, 146, 160, 174, 188 and 202 days in three trench silos. The samples were brought to laboratory every 14 days. This process was repeated 9 times. After the 132th day, whereas silage crude protein (CP), ether extract (EE), ash and crude fiber (CF) contents decreased, nitrogen free extract (NFE) content increased. Lactic acid concentration of corn silage increased until the 118th day but decreased between the 118th and the 160th days. On the contrary, of decrease in LA concentration, acetic acid concentration increased depending on storage time. Ammonia nitrogen and CO2 concentration of silage increased decreased with progressing time. Storage time had significant influence on Flieg scores. The lowest score was found between days the 104th-118th. In this research, it was observed that there was a change in silage nutrient contents and fermentation characteristics with increasing storage time.

The study was conducted to investigate the effects of ensiled guinea grass (GG)- cassava peel (CSP) enriched with soybean cheese waste (SBCW) in varying proportions into 4 treatments: T1 (GG100%), T2 (GG80% + CSP10% + SBCW10%), T3 (GG60% + CSP30% + SBCW10%) and T4 (GG40% + CSP50% + SBCW10%) on West African Dwarf goats. Twenty WAd goats were allocated into four silages of five growing WAd goats each. Daily feed intake and weekly weight gain were measured for twelve weeks of the experiment. Digestibility study was carried out using Three animals per treatment for faeces and urine collection. Blood samples were collected via jugular vein for blood profile analysis using standard measures in a completely randomized design. The Crude protein (CP) concentrations of silage increased with the increasing level of cassava peels. Crude fiber levels of the silages also followed the same trend. The group of animals fed T4 had highest feed intake among the treatment groups. Daily weight gain of goats in T4 was better enhanced than other treatments. The apparent digestibility was significantly different (P˂0.05) among the treatment groups. There were diet effects on the parameters measured for rumen liquor of the animals fed silages. The treatments had no effects on the haematology and total protein of goats fed diets. It is therefore indicated that agro-industrial by-products ensiled with guinea grass are potential means of feed sustainability during the dry season period for goats in Nigeria without any deleterious effects on goats’ health and performance.

The purpose of this study was to investigate how the addition of rosemary to corn silage affected the quality, fermentation, and in vitro digestion of organic matter. In the study, unaltered silage group constituted the control group, while silages prepared by adding 0.5, 1 and 2% rosemary constituted the experimental groups. After 60 days of ensiling, the pH of the opened silages was determined to be in the range of 3.67-3.72. As the amount of rosemary in the silages increased, the levels of ammonia nitrogen (NH3-N/TN) decreased. Compared to the control group, increases in in-vitro organic matter digestion (IVOMD) and metabolizable energy (ME) values were observed in the experimental groups due to the addition of rosemary. In comparison to the control group, the methane gas (CH4) rate of silages was reduced in the other groups. Meanwhile, the group receiving 2% addition of rosemary had the highest values of acetic acid (AA) and lactic acid (LA) among the supplemented silage groups. But, propionic acid (PA) and butyric acid (BA) were not detected in any of the silage groups. Consequently, it was determined that 1% and 2% of rosemary added to corn silage can enhance the quality of the silage.
