“…With permeability to oxygen of just 50 cm 3 m −2 d −1 , ROMOS bags are even better than the recently developed oxygen barrier film, with an oxygen permeability of 70 cm 3 m −2 d −1 31. However, studies of Ashbell et al 32 indicate that oxygen permeability through the plastic bag is not a crucial factor for maintaining acceptable silage quality, so long as the bag is intact and the inside atmosphere contains volatile fatty acids at levels of 15–20 g kg −1 DM. The authors tested different types of commercial plastic bags and found that permeability to oxygen ranged from 43 to 504 cm 3 m −2 d −1 , with good‐quality silages in all tested materials.…”

“…In spite of large differences in gas permeability among the bags, acceptable silage quality was obtained in all bag types. Ashbell et al. (2001) concluded that oxygen permeability through the bag material is not a crucial factor for maintaining acceptable silage quality, as long as the bag is intact.…”

The aim of the investigation was to determine the influence of variations in thickness and colour of agricultural plastic film on silage preservation conditions and grass silage quality. For this purpose, 30 cylindrical plastic containers (mini‐silos; 0·3 m3) were filled with chopped grass and covered with five films of different thickness and colour: 90 μm, white; 125 μm, green; 150 μm, black; 200 μm, green and 200 μm, white. Four replications of each film type were placed in the open air. Two replications were housed indoors and exposed to an ‘artificial sky’ in a test apparatus. The surface temperature of the films was found to be strongly dependent on film thickness and colour. Results of the chemical analysis of silages did not reveal any significant influence of the films. This was also the case when restricting the analysis to the uppermost silage layer. The results showed that under the conditions of this experiment, well preserved forage can be produced with films of differing colour, as well as of lesser thickness.

“…As a technically sound method, ensiling is considered the most proper utilization of greenery byproduct residues and a convenient preserving method with optimal quality and quantity and minimal natural losses [23]. Ashbell et al [24]. and El-Shaer [25] highlighted ensilage as a potential livestock fodder in arid and semi-arid areas.…”

There is a chronic shortage of local feeds in Kuwait, and almost 95% of total feeds are expensively imported. Therefore, efforts were focused to explore the possible utilization of locally available landscape browse residues as feed ingredients. Landscape greenery residues have increased with locally implemented greenery programs. Conocarpus lancifolius is an ornamentally predominant tree among landscape plantations, daily resulting in over 120 t of residual by-products without being utilized. Ensiling, was considered as a technically sound strategy for proper utilization of Conocarpus residues as an upgraded feed ingredient substituting imported conventional feeds. A total premix of 24 t of silage was prepared in pilot-scale trench silos for 30 days. Nutritional value of Conocarpus silage was evaluated, where mean values of 4.2 ± 0.12, 4.95 ± 0.32%, and 7.3 × 108 ± 0.12 colony forming units (CFU)/g of silage for pH, lactic acid, and lactic acid bacteria were achieved, respectively. Palatability and feeding trials were performed for four months on 60 growing heifers of Holstein-Friesian breed grouped in six dietary treatments. Formulated feed rations contained 20, 30, 40, 50 and 60% silage partially replacing conventional roughages (alfalfa, hay straw). Control dietary treatment contained 100% conventional feed ingredients. Daily dry matter intake and feed conversion ratio were signifi cantly (p > 0.05) high. Results showed that grossly 40% of the conventional roughages could be replaced by the ensiled Conocarpus greenery browse residues. Cost/benefi t analysis was carried out on pilot-scale production of Conocarpus silage, confi rming a feasible, low cost, and competitive product where the cost was calculated to be Kuwaiti Dinar 33 (US$ 120)/t silage. Break-even point could be achieved after 30 months with production of 3,159 t silage. Potentially, low-cost Conocarpus silage could partially substitute expensive imported roughages, thereby alleviating feed shortage and, currently, promoting livestock production.
