“…According to Wilkinson (2005) silages should contain 72 -89 g CP/kg DM (McDonald, 1981) and 9.6 -12.2 MJ ME/kg DM and would require supplementation to achieve a daily gain of more than 150 g/d in commercial lamb operations (Marley et al, 2007). Feeding lambs on silage alone generally leads to either loss of live weight or limited daily gains (Fitzgerald, 1986).…”

________________________________________________________________________________ AbstractThe aim of the study was to determine the effect of whey or molasses on the fermentation quality when added to potato hash silage. In addition, lamb performance, digestibility and feed intake of diets containing potato hash silage were compared with a diet containing maize silage (MSd). Potato hash silage (treated with no additive, or whey, or molasses) and MS were produced in 210 L drums for 90 days and the fermentation quality of the silages was determined thereafter. Diets were formulated and fed ad libitum to 32 South African Dorper lambs (23.5 ± 0.873 kg live weight) for 63 days. A digestibility study was conducted during the last week of the study. The untreated potato hash silage (UPHS) was poorly fermented as indicated by higher concentrations of butyric acid, ammonia-N and pH compared to the other silages. Higher dry matter intake (DMI) and daily weight gains (218 and 250 g/d) were obtained with MSd and molasses treated potato hash silage diet (MPHSd) compared to the other diets. Nutrient digestibility was lower in the UPHS diet compared to the other dietary treatments. It was concluded that the fermentation quality of potato hash was improved with the addition of whey and molasses. Furthermore, growth performance was higher with the MSd and MPHSd than of the other treatments, suggesting that MPHSd can safely replace MSd in a lamb diet at a dietary inclusion level of 20% without any adverse effect on animal performance. ________________________________________________________________________________

“…To overcome this inefficient balance of dietary nutrients, increasing the amount of energy provided in the form of concentrates (Dewhurst et al, 2003) is not conducive to the principles of organic farming. Alternative, and more 'natural' approaches, may include the use of ryegrass that has been bred to express high water-soluble carbohydrate concentrations (Lee et al, 2001;Marley et al, 2007a) or feeding alternative high-energy forages, such as forage brassicas, which have been shown to improve voluntary intake and N utilisation in ruminants (Marley et al, 2007b).…”

This review provides an assessment of research findings into the current practices and standards and the principles and aspirations for organic dairy production, with respect to the health and welfare of the dairy cow. The relationships between the four main factors: management, environment, genetics and nutrition and their impact on the health and welfare status of organic dairy cows are considered. The concept that good animal health and welfare is more than merely the absence of disease, with behavioural aspects of health and welfare such as physiological and psychological needs, is also discussed. These factors are inter-related and important in all dairy systems, irrespective of whether the system is organic, low-input or intensive. Incidences of individual clinical and sub-clinical diseases that are recorded in conventional dairy systems also occur in organic dairy systems, with infertility, lameness and mastitis being the major problems. However, the magnitude of the incidence of many of these diseases may be either lower or higher in organic systems due to different management practices and the standards defined for organic milk production that, for example, prohibit the routine use of conventional medicines and require the feeding of high-forage diets. In relation to different systems, it is important to note that contrary to a common assumption, good welfare does not necessarily occur with more extensive systems. The type of organic system (self-sufficient, purchased-feed) also has the potential to have a major influence on the incidence of health problems and the reproductive status of organic dairy herds. Health status is also influenced by environmental and welfare factors, including the method of rearing replacement animals, type of housing and the geographical and climatic conditions of individual farms. Overall, this review identifies where conflicts arise between current practice and the organic principles and standards, and aims to provide suggestions to bring about further improvement in organic dairy health and welfare.

“…Silage technology has opened the possibility for utilizing green residues for feeding livestock [22]. 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].…”

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.
