“…Starch is the main source of energy in CS and is a quantitatively important nutrient for the performance of dairy cows (Jensen et al, 2005). Rezaei et al (2014) noted that CS produced in warm climate regions tended to present lower starch concentrations, which is similar to that reported in current study (20.1% DM basis, Table 1), but is lower than those stated in NRC (2001) tables (i.e., 32% DM basis).…”

“…Miron et al (2007) reported a similar concentration of DM for SS (29% of DM), whereas Oliver et al (2004) showed greater DM concentrations for both SS and CS compared with our results (30 vs. 34.4% of DM, respectively). The differences in DM concentration among the studies are probably due to factors such as soil, climate, planting date, crop management, stage of maturity, and season (McDonald et al, 2011;Rezaei et al, 2014).…”

Total mixed rations containing corn silage (CS) or forage sorghum silage (SS) were fed to mid-lactation Holstein cows to determine the effects on feed intake, lactation performance, milk composition and fatty acid profile, nutrient digestibility, blood metabolites, rumen microbial N synthesis, and antioxidant status. The experiment was designed as a 2-period changeover (two 28-d periods) trial with 2 diets including CS diet or SS diet and 12 cows. Total replacement of CS with SS had no significant influence on dry matter intake. Substituting CS with SS had no effect on milk production, feed efficiency, and milk concentrations of fat, protein, lactose, and solids-not-fat, whereas yields of milk fat, protein, and lactose were greater for cows fed the CS diet. Blood parameters including glucose, albumin, cholesterol, triglyceride, total protein, urea N, and fatty acids were not affected by the dietary treatments. Apparent digestibility coefficients of dry matter, organic matter, crude protein, ether extract, neutral detergent fiber, and acid detergent fiber were not significantly influenced by the diets. Replacing CS with SS had no effect on total saturated fatty acids and total monounsaturated fatty acids, whereas total polyunsaturated fatty acid percentage was greater with the SS diet. Proportions of C20:0, C18: 3n-3, and C18: 3n-6 were affected by feeding SS. Cows fed CS had a greater amount of urinary purine derivatives. Feeding SS had a positive effect on total antioxidant capacity of blood and milk. In conclusion, SS can be fed to lactating Holstein cows as a total replacement for CS without undesirable effects on animal performance, but with positive effects on antioxidant capacity and polyunsaturated fatty acids of milk. This forage can be an excellent choice for dairy farms in areas where cultivation of corn is difficult due to water shortage.

“…Amaranth has a moderate to great OM disappearance (OMD; 618 to 734 g/kg; Abbasi et al, 2012). The main stem axis and high moisture concentration make quick drying of a large biomass of grain-type amaranth difficult (Abbasi et al, 2012;Rezaei et al, 2014), and this limits its use as a dried forage. Therefore, ensiling is recommended to conserve amaranth (Rezaei et al, 2014).…”

This study assessed the influence of wilting, lactobacillus (LAB) and / or molasses on the chemical composition, phenolic compounds, in situ degradability and in vitro ruminal fermentation parameters of amaranth (var. Maria) silage using a randomized complete block design with 6 replicates. Treatments were fresh amaranth forage (FAF), ensiled amaranth without additive (EA), EA inoculated with LAB (EAB), EA + 5% of molasses (EAM), EA inoculated with LAB + 5% of molasses (EABM) and 24-h wilted EA (WEA). The ensiled materials were stored anaerobically for a period of 45 d. Chemical composition, oxalic acid and nitrate levels, silage fermentation characteristics, DM disappearance (DMD), OM disappearance (OMD), in vitro ruminal ammonia-N, VFA, cellulolytic bacteria and protozoa counts, and in situ DM and CP degradability were determined. Compared with FAF, EA had a lesser values of water-soluble carbohydrates (P = 0.023), nitrate (P = 0.001), total phenolics (P = 0.04), total tannins (P = 0.01), DMD (P = 0.01), ruminal cellulolytic bacteria (P = 0.02), soluble and very rapidly degradable fraction (P = 0.014), and effective degradability (P = 0.01). The EA had lesser OMD and CP degradability compared with FAF (P < 0.05). Adding molasses to EA resulted in increased ash and lactate concentrations and decreased ammonia (P < 0.05), but had no effect on OMD. The WEA had lesser ammonia and greater lactate compared to EA (P < 0.05). Overall, fresh amaranth var. Maria can be preserved as a valuable silage to feed ruminants. Ensiling amaranth var. Maria decreased the anti-quality compounds, and molasses addition improved the fermentation quality of the silage.

“…The improved MPS in the animals fed diets containing up to 140 g/kg of DBL compared to those fed the control diet could be due to increased intakes of DM and CP (Rezaei et al, 2014). Higher DM digestibility, and thereby increased daily ME intake, and greater CP supplied by diets, may have resulted in better synchrony of ME and N in the rumen of sheep fed the diets containing up to 140 g DBL/kg DM.…”
