“…The proliferations of yeasts, aerobic bacteria and molds cause the increase in temperature and pH, result in the nutrients loss and increase the risk of proliferation of potential pathogenic or undesirable microorganisms, thus affecting the performance of animals fed the silage [27]. Kung Jr and Ranjit [28] defined the aerobic stability as the number of hours that the silage remained stable before increasing more than 2°C above the ambient temperature.…”

ObjectiveThe objective of this study was to evaluate the effect of sodium diacetate (SDA) on fermentation profile, chemical composition and aerobic stability of alfalfa (Medicago sativa L.) silage.MethodsFresh alfalfa was ensiled with various concentrations of SDA (0, 3, 5, 7, and 9 g/kg of fresh forage). After 60 days of the ensiling, the samples were collected to examine the fermentative quality, chemical composition and aerobic stability.ResultsThe application of SDA significantly (p<0.05) decreased silage pH with the lowest value in silage with 7 g/kg of SDA. The proliferations of enterobacteria, yeasts, molds and clostridia were inhibited by SDA, resulted in lower ethanol, propionic and butyric acid concentrations and dry matter loss in SDA treated silages than control. The increasing SDA linearly decreased free amino acid N (p<0.001), ammonia N (p = 0.018) and non-protein N (p<0.001), while linearly increased water soluble carbohydrate (p<0.001) and peptide N (p<0.001). It is speculated that SDA accelerated the shift from homofermentative to heterofermentative lactic acid bacteria during the silage fermentation, indicated by lower lactic acid production in SDA-9 than SDA-7 silages after 60 days of ensiling. Alfalfa silages treated with SDA at 7 g/kg had highest Flieg’s point and remained stable more than 9 d during aerobic exposure under humid and hot conditions in southern China.ConclusionSDA may be used as an additive for alfalfa silages at a level of 7 g/kg.

“…However, in some countries, such as Canada and US, soybean first use was as forage crop, which shows an increased interest in livestock production systems. Soybean silage can supply the protein requirements of the animals, reduce the feed costs, improve the profitability, and benefit the soil fertility and structure when intercropping with others grains crops (Vargas-Bello-Pérez et al, 2008;Spanghero et al, 2015;Nkosi et al, 2016).…”

The objective of this study was to evaluate the performance, feeding behavior, carcass traits, and meat quality of feedlot lambs using 2 types of silage, sorghum or soybean. Twenty-eight male non-castrated market lambs weighting 20 ± 2 kg were used. Diets were formulated to be isonitrogenous and isocaloric. The animals were slaughtered after 50 days of experiment, with 32.13 ± 5.09 kg of body weight. Lambs fed with soybean silage showed increased time for feed intake (P = 0.01). There was no difference for allowed daily gain, dry matter intake, feed conversion, and carcass traits between diets. Meat from lambs fed with soybean silage showed decreased shear force (P = 0.001) compared to sorghum silage, with no differences (P > 0.05) for chemical composition, color, and cooking loss. The intake of sorghum silage increased (P < 0.05) C6:0, C16:0, C20:0, C14:1, and C16:1 fatty acids content of Longissimus lumborum intramuscular fat. The intake of soybean silage showed an increased (P < 0.05) content of C18:1ω9t, C18:2ω6c, and sum of ω6 fatty acids. The feed cost and profit from the use of sorghum and soybean silage were US$ 0.

“…Seppälä, Heikkilä, Mäki, and Rinne (2016) stressed that the purpose of using additives during ensiling is to inhibit the growth of undesirable micro-organisms so as to prevent spoilage of the feed, thereby minimizing energy and nutrient losses. The use of chemical additives in the ensiling of tropical forages has been tested for over two decades (Felix & Funso, 1994;Mahouachi, Haddad, Kayouli, Théwis, & Beckers, 2003;Miron, Kabala, Tockb, & Ben-Ghedalia, 1995), and the improvement and efficiency of production of preserved roughages (Nkosi et al, 2016;Roth et al, 2016) have been gradually contributing to animal production. Romão et al (2013), Chizzotti et al (2015) and Martins et al (2015) investigated and described the use of urea and calcium oxide as alkalinizing chemical additives in the ensiling of sugarcane.…”

This study aimed to evaluate the effect of pearl millet silage ammoniated with urea on lamb carcass characteristics and meat quality. Thirty-two noncastrated crossbred lambs at 4-5 months of age, with an average initial body weight of 17.39 ± 2.16 kg, were distributed into four treatments in a randomized block experimental design with eight animals per treatment. Experimental diets were composed of pearl millet silage ammoniated with four levels of urea (0%, 2%, 4% and 6%, on dry matter basis (DM). Carcass conformation and fatness decreased linearly (p < 0.05). Except for the fat content, the proximate composition was not influenced (p < 0.05) by the diets. Meat lightness and yellowness increased linearly (p < 0.05). There was no effect of diets (p > 0.05) on cooking losses or shear force. The levels of oleic and erucic fatty acid levels in the meat decreased linearly (p < 0.05), whereas linoleic and eicosadienoic acids, polyunsaturated fatty acids, PUFA:SFA ratio and ω6 contents increased (p < 0.05). Pearl millet silage ammoniated with urea allows for the production of good-quality lamb meat, with greater concentrations of polyunsaturated fatty acids. However, lambs fed diets with pearl millet ammoniated with up to 6% lead to a reduction of carcass characteristics without significantly affecting loin-eye area possibly associated with low palatability of the additive used. The lower acceptance of the silages with higher levels of urea is due to the ammonia retention in the material is attributed to the ammonization process. Thus, in spite of the benefits on lamb meat quality, it is suggested that the use of this additive in the ammonization of tropical forages be carried out with care, in limits of up to 6%.
