This experiment aimed at determining the effect of farmyard manure (FYM)applicationon a natural pasturein Western Serbia, with a 30 t ha-1treatment incomparison to control (no fertilizer added) during two years (2012-2014).The FYMwas applied in the autumn of 2012 and the trial plots were harvested twice a year.Dry matter (DM) yield and forage quality - content of crude protein (CP),nonprotein N (%CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) andnet energy for lactation(NEL), were estimated for each production year. Treatmentwith manure gave a higher DM yield compared to control plots in bothexperimental years (5.91 t ha-1 vs. 3.01 t ha-1 in 2013, and 2.76 vs. 2.03 t ha-1 in2014). As expected,the yield in the second cuts of both years was much lower thanin the first cuts. The FYM application did not affect chemical composition and netenergy concentration of forages, whereas significant effects of different cuts werefound, but were inconsistent between the first and second experimental year. Ingeneral, it can be concluded that application of FYM did not have a significanteffect on forage quality ina permanent grassland, whereas chemical compositionwas significantly affected by different cuts and experimental years. Based on theresults, a grassland may have a good DM yield response if FYM is used as afertilizer, while the effect on forage qualitymay be much weaker.

Established stands of alfalfa (Medicago sativaL.) at two field locations were treated at one date in the fall with pronamide [3,5-dichloro (N-1,1-dimethyl-2-propynil) benzamide] at 0.8 and 1.6 kg ai/ha and at two dates in the spring with sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} at 0.3 and 0.6 kg ai/ha for the control of quackgrass [Agropyron repens(L.) Beauv. # AGRRE]. Herbicide efficacy was compared by measuring botanical and chemical composition and yield of forage. Both chemicals suppressed quackgrass in first-cutting herbage. While sethoxydim at the higher rate was equivalent to pronamide for increasing the proportion of alfalfa in forage, pronamide was superior for increasing seasonal total yield. Late postemergence applications of sethoxydim were more effective for quackgrass regrowth control than earlier spring applications. Controlling quackgrass in late spring resulted in lower crude protein (CP) content in first-cutting forage than did controlling it in fall. Alfalfa competing with untreated quackgrass had a lower CP content than where quackgrass was controlled with herbicides. All herbicide treatments reduced the neutral-detergent fiber (NDF) of the herbage. As measured by the acid-detergent fiber (ADF) concentration of alfalfa, sethoxydim slightly retarded spring growth of the legume.

Ruminal Degradability

A study was conducted to determine the effects of forage soybean cultivar on chemical composition, ensiling characteristics, and ruminal degradability of silage. Two cultivars of forage soybean (Kodiak and Mammouth) were field-grown, harvested at the R6 stage, and ensiled in mini-silos (n = 3) for 0, 2, 4, 8, 16 and 45 d. Two ruminally fistulated cows were used to determine in situ ruminal nutrient degradabilities of the 45-d silages. Both cultivars went through slow fermentation as indicated by a gradual decline in pH up to day 45 post-ensiling. Lactic acid concentration increased throughout ensiling and was higher for Mammouth than Kodiak except at day 45 post-ensiling. Analysis of the 45-d silages showed that Mammouth contained higher neutral detergent fiber (NDF, 490 vs. 444 g kg-1), acid detergent fiber (371 vs. 353 g kg-1) and acid detergent lignin (81 vs. 64 g kg-1) than Kodiak. However, crude protein (CP) concentration was higher for Kodiak than Mammouth. Mammouth silage had lower buffer soluble protein and higher neutral and acid detergent insoluble protein concentrations than Kodiak silage. Results of the in situ study indicated that Kodiak silage had greater ruminal dry matter (606 vs. 549 g kg-1), CP (828 vs. 752 g kg -1) and NDF (272 vs. 227 g kg-1) degradabilities than Mammouth. It was concluded that chemical composition and ruminal nutrient degradabilities of forage soybean silage were significantly influenced by cultivar. Key words: Soybean [Glycine max (L.)

In this study, it was aimed to determine some forage quality characteristics of sweet sorghum genotypes in semi-arid climatic conditions. The experiment was set up in randomized complete block design with 4 replicates. Research was carried out in 2016 and 2017 under Harran Plain second crop conditions, Sanliurfa, Turkey. In the study 21 genotypes of sweet sorghum were used. Crude protein content, crude ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), dry matter digestibility, dry matter consumption, were determined in the study. Significant differences were found between the genotypes for tested characteristics (P≤0.01). According to average of two years, crude protein content ranged from 4.20% (Tracy) to 5.90% (USDA S.Africa), crude ash from 4.44% (Theis) to 6.90% (Topper 76), acid detergent fiber (ADF) from 27.84% (Nebraska sugar) to 36.30% (USDA-Zaire). The highest NDF value was obtained from USDA-Zaire genotype (56.49%) whereas the lowest values were seen at N98 genotype (43.11%). Dry matter digestibility values were between 60.62% (USDA-Zaire) and 67.21% (Nebraska sugar), dry matter consumption between 2.14% and 2.85%. The highest relative feed value was obtained from N98 genotype (148.95) whereas the lowest values were seen at USDA-Zaire genotype (101.00). Net energy values ranged from 1.38 Mcal kg-1 (USDA-Zaire) to 1.50 Mcal kg-1 (Nebraska sugar). Considering the properties examined in terms of feed quality, it was seen that the crude protein content and net energy value was low. But ADF, NDF, digestible dry matter, dry matter consumption and relative feed values were within acceptable levels. Nebraska sugar, Topper 76, N98, Roma, M81E, Tracy and Corina genotypes were found as the best for forage quality in sweet sorghum. It was determined that sweet sorghum can be used as a forage source.

Objectives: To determine the chemical composition and in vitro digestibility of Acacia angustissima, Dalea spp., Desmodium spp., Leucaena leucocephala, Phaseolus vulgaris and Tephrosia vicioides (Fabaceae) fodder species. Design/Methodology/Approach: Crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude lignin (CL), cellulose (Cel), hemicellulose (Hcel), cellular content (CC) and in vitro dry matter digestibility (IVDMD) were determined. The design was completely random with three repetitions. The variables were correlated by pairs and the means of the species were compared with Tukey’s test (P<0.05). Results: Dalea spp. had the highest crude protein (17.7%), followed by A. angustissima (15.9%) and L. leucocephala (14.1%). A. angustissima (73.2%), Dalea spp. (74.9%) and P. vulgaris (77.5%) showed the highest IVDMD. L. leucocephala, Tephrosia vicioides and Desmodium spp. showed the lowest values of CP (14.1, 11.8 and 12.3%, respectively) and IVDMD (70.4, 70.2 and 64.9%, respectively). Desmodium spp. showed high levels of NDF (59.2%), ADF (41.4%), CL (17.5%), Cel (29.7%) and Hcel (17.8%) (P?0.05). IVDMD showed positive correlation with CC and negative correlations with NDF, CL, and Hcel (P<0.05). Study Limitations/Implications: Desmodium spp. showed high content of CL and low values of CP and IVDMD, therefore supplements should be added when used in animal feed. Findings/Conclusions: Dalea spp. showed low levels of lignin and high levels of protein and digestibility, making it posible to use as feed for ruminants

Abstract: The objective of this work was to assess the nutritive value of four elephant grass (Pennisetum purpureum) genotypes. The chemical composition, intake by sheep, and digestibility of different genotypes (G1, G2, G3, and G4) were evaluated. A dry matter (DM) digestibility assay was performed with total leftovers and feces collected from 20 sheep kept in metabolic cages. G3 had lower DM intake in grams per animal per day compared with G1 and G2, and it had greater digestibility, crude protein, neutral detergent fiber, and acid detergent fiber values. G1, G2, and G4 have the best nutritive values among the evaluated genotypes.

Abstract A laboratory experiment was conducted to examine the effects of microbial fermentation using Bacillus subtilis and Aspergillus oryzae on the chemical composition of a commercial soybean meal (SBM). Five quadruplicate samples of SBM were subjected to four treatments with one batch serves as a control. The treatments were steam conditioning treatment (P1) where the other three groups were further fermented with B. subtilis (P2), A. oryzae (P3), and the combination of B. subtilis + A. oryzae (P4). The results showed that bacterial and fungal inoculation increased crude protein (CP) content when compared to control (p<0.05). In addition, fiber fractions including neutral detergent fiber (NDF) and acid detergent fiber (ADF) were concomitantly decreased with fermentation (p<0.05). In this study, no significant difference was observed on CP and NDF content with heating treatment (P1, p>0.05). However, this treatment decreased ADF content (p<0.05). Ether extract (EE), ash, non-fibrous carbohydrates (NFC), and total phosphorus contents were not affected by the treatments. To conclude, fermentation either with bacterial or fungal inoculants was effective to improve the chemical composition of SBM as indicated by increasing CP and decreasing fiber contents of SBM.

Abstract The objective was to evaluate the chemical composition and in situ degradation of Maasai, Mombasa and Tanzania grasses belonging to the genus Panicum, at 22, 34 and 46 days after regrowth. The contents of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) were determined. For the evaluation of ruminal degradation, 4 g sample were placed in nylon bags and incubated in the rumen of a fistulated animal, for 6, 24 and 72 h. The experiment had a completely randomized design for chemical composition analysis and a split-split plot completely randomized design for in situ degradation, with means compared by Tukey test at 5%. There was an increase in the contents of DM (+ 1.69%) and NDF (+ 5.06%) (P <0.05) of the grasses at the highest cutting ages with reduction in the CP fraction. The potential degradation (PD) of DM, NDF and CP decreased with advancing age of grasses, with an increase in colonization time (0.69 h) and NDF degradation rate (1.14%/h). The increase in the post-regrowth age of the Massai, Mombasa, and Tanzania grasses increases the acid detergent fiber content and reduces the crude protein content, with a negative effect on the degradation of DM, PB and NDF. The management of these cultivars is indicated at 22 and 34 days post-regrowth to obtain forage with better nutritional value.

Forage Yields

Eighteen alfalfa (Medicago sativa) cultivars were evaluated as to dry forage and crude protein yields at the Lajas Research and Development Center; there were 6 cuttings during a 232-day period. Dry forage yields ranged from 4,673 kgfha for Tanverde (lowest) to 11,675 kg/ha for Maracay (highest) cultivar. Good yields were also obtained with Florida 66, Moapa, Peruvian, Certified Mesa Sirsa, and Hayden PX-1 cultivars. Stand persistence declined markedly after the fifth harvest due to Phytophthora root rot infestation. Maracay, Florida 66, and Certified Mesa Sirsa showed the best persistence through the sixth cutting. Mean overall values for neutral-detergent fiber, acid-detergent fiber, lignin, cellulose, silica, crude protein, phosphorus, and potassium contents for the 18 cultivars were 34.86, 29.13, 10.22, 17.08, 1.42, 21.86, 0.36, and 2.08%, respectively. Insects were not a major problem in this study.

Due to the seasonal cycle of forage, the use of silage to feed animals provides nutrients throughout the year. However, its quality can be improved with the inclusion of additives and other products. Glycerol is a rich source of energy and present a high efficiency of utilization by animals. The purpose of this work was to evaluate the effect of glycerol inclusion on the chemical and fermentation characteristics of corn and sunflower silages. Two silage sources (maize and sunflower) were used and four levels of glycerol inclusion (0, 15, 30 and 45%) based on dry matter were carried out. The experimental design was completely randomized in a 2 x 4 factorial arrangement with five replications. The pH values and chemical composition of corn and sunflower silages were determined. In both silages there was increment of dry matter, non-fiber carbohydrates and total digestible nutrients (TDN) added to a reduction of crude protein, neutral detergent fiber and acid detergent fiber due to the glycerol inclusion. The corn silage required 45% glycerol to achieve the TDN level of the sunflower silage. The glycerol addition contributed to the increase in the nutritional value, offsetting loss of quality in the ensiling process.

This study evaluated the chemical composition and ruminal degradability of dry matter (DM), neutral detergent fiber corrected for ash and protein (NDFap) and crude protein (CP) in byproducts of African oil palm (palm cake, kernel or fiber), macaúba (pulp cake and kernel cake), acai (acai fruit), babassu (kernel cake) and pineapple (peel, crown and bagasse silage). Nineteen rumen-fistulated sheep were kept in individual stalls, receiving a daily diet composed of elephant grass silage and corn and soybean concentrate. After preparation in nylon bags, the byproduct samples were incubated for 0, 3, 6, 12, 16, 18, 24, 48, 72, 96, 120 and 144 hours, with three replicates of each ingredient per incubation time. The divergence between the protein nutritional value and energy nutritional value, based on discriminatory variables between groups, was estimated by cluster analysis. The effective degradability of DM, NDFap and CP for the different byproducts was, respectively, 35.9, 26.9 and 59.0% for palm cake; 48.3, 34.3 and 76.4% for palm kernel; 21.1, 6.6 and 50.3% for palm fiber; 34.3, 15.0 and 52.8% for macaúba pulp cake; 58.1; 63.0 and 51.6% for macaúba kernel cake; 49.7, 49.6 and 41.8% for babassu cake; 53.4, 40.5 and 79.8% for pineapple bagasse silage; and 21.3, 17.0 and 38.9% for acai fruit. Based on their NDFap and CP characteristics, the feeds were clustered in up to four different groups.
