“…The digestibility of NDF, ADF and gross energy were not affected by treatment (P ≥ 0.12). The low values of DM and crude protein digestibility in steers fed STMR suggested an imbalance between available energy and nitrogen (N) in the diet, with available N being greater than available energy (Chizzotti et al 2009). This is supported by the ruminal NH 3 -N content of steers fed STMR being greater (P = 0.01) than other groups at 4 h after feeding (Table 5).…”

Our objective was to determine the effect of forage ensiling and ration fermentation on total mixed ration pH, ruminal fermentation and animal performance. Thirty Holstein-Zebu cross steers were allotted to feeding treatments for 188 days in a randomized complete block design including: fresh grass-total mixed ration (GTMR; pH 4.7), grass silage-TMR (STMR; pH 4.0) and fermented-TMR (FTMR; pH 3.5). Average daily gain for STMR was greatest during the first 3 months period; however, that for FTMR tended to be greater than GTMR during the second 3 months period (P < 0.10). During the second period dry matter intake for STMR was the greatest (P < 0.01), but feed conversion ratio (P < 0.01) and cost per gain (P < 0.01) were the least for FTMR. Protein digestibility tended (P < 0.10) to be greater for FTMR than STMR and fat digestibility was greater (P < 0.05) for GTMR and FTMR than STMR. FTMR had less (P < 0.01) ruminal NH -N content than STMR. Total volatile fatty acids post-feeding was greatest for GTMR (P < 0.01). Ruminal proportions of acetic and butyric acids were greater for FTMR than GTMR (P < 0.05); in contrast, propionic acid was greater for GTMR (P < 0.05). Utilizing silage or total ration fermentation did not negatively impact on ruminal pH. STMR and FTMRs can be used to maintain performance of growing crossbred Holstein steers.

“…observed no palatability problems though their research studies reported that grass silage can produce as much milk per cow as alfalfa silage when rations are balanced. Rodrigues et al [104], Barrière et al [105]., Pereira et al [106] and Chizzotti et al [107]. all reported satisfactory DM intake with appropriate concentrate levels of diets containing grass hay or silage as roughage.…”

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.

“…The complete rich diet containing concentrates combined with good Conocarpus silage lead to high growth rates for the experimental heifers groups. Barrière et al (2004), Chizzotti et al (2009), Dalton et al (2008) and Rodrigues et al (2002), reported satisfactory DM intake with appropriate concentrate levels of diets containing grass hay or silage as roughage. On the other hand, Carvalho et al (2006) and Evans et al (2004) found no effect of concentrate ratios on DM intake, while Pereira et al (2008) traced digestibility parameters in beef cattle-fed diets containing silage and concentrates.…”

Conocarpus lancifolius is an ornamental tree planted in Kuwait, resulting in more than 120 t of residual by-products daily. These residues could be utilised as ensiled feed. A total premix of 24 t of silage was prepared in six pilot-scale trench silos for 30 days, after which triplicate samples were taken from each trench silo, which were analysed for nutritional contents and microbial populations. Mean pH value was 4.2 ± 0.12, where mean of dry matter (DM), crude protein, crude fats, crude fibre, organic matter, lactic and acetic acids and total water soluble carbohydrate concentration were 35.10 ± 4.0%, 11.18 ± 0.07%, 2.47 ± 0.21%, 20.85 ± 0.95%, 19.53 ± 0.53%, 4.95 ± 0.32%, 1.47 ± 0.01% and 20.86 ± 0.56% on DM basis, respectively. Means of aerobic bacteria, fungi (yeast and moulds) and lactic acid bacteria counts were 1.8 ×10 4 ± 0.15, 1.1 × 10 4 ± 0.09 and 7.3 × 10 8 ± 0.12 colony forming units per gram of fresh silage, respectively. An animal performance trial was conducted on 60 Holstein Friesian heifers with initial live weights ranging from 262 to 275 kg, grouped in six dietary treatments for a 148-day feeding trial. The diets contained different ratios of Conocarpus silage, which ranged from 10 to 60% on DM basis partially replacing conventional roughage (alfalfa hay, straw). DM intake of heifers ranged between 11.40 ± 2.14 kg and 13.61 ± 2.54 kg. Daily live-weight gain ranged from 0.99 ± 0.38 kg to 1.20 ± 0.31 kg. From the results, Conocarpus silage could be suggested as a replacement for conventional roughage in rations for growing heifers.
