Medicago Sativa L

This research was conducted to determine performances of seven alfalfa cultivars with different fall dormancy rates in terms of dry matter yield and some quality parameters under Mediterranean conditions throughout the years of 2007-2009. In the study, cultivars were evaluated for dry matter yield (DMY), leaf/stem ratio (LSR), crude protein (CP) content, crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM) content and relative feed value (RFV). According to average of two year results, there were significant differences among alfalfa cultivars in terms of all characters studied. Mean DMY, LSR, contents of CP, ADF, NDF, DDM and RFV were determined as 18.147 t ha-1, 0.82, 17.4 %, 41.0 %, 49.0 %, 56.9 % and 114. The highest DMY averaged over two years was obtained from cultivar Nimet while lowest one was obtained from Magnum 5. As a dormant cultivar, Magnum 5 was superior in terms of LSR and CP content to the other alfalfa cultivars and it was lower in ADF and NDF content than the others. It was concluded that cultivar Nimet with the highest DMY and CPY yields can be recommended as a non-dormant cultivar for farmers in regions of Turkey with the Mediterranean climate.

This study was conducted to determine the effect of row spacing (40, 60 and 80 cm) on forage dry matter (DM) yield and quality of four hybrids grown in the years 2001 and 2002. The highest DM yield was obtained from the Arifiye (24.1 and 22.4 t/ha) while the lowest DM yield was obtained from Pioneer 3163 (19.9 and 19.8 t/ha) in the years 2001 and 2002, respectively. As row spacing increased, DM yield as an average of two years decreased from 27.2 to 16.6 t/ha. No differences were found among row spacing for DM content, harvest index (HI) and ear content. As row spacing increased, whole-plant acid detergent fiber (ADF) and neutral detergent fiber (NDF) content increased from 214 to 227 g/kg and from 420 to 451 g/kg during the year 2001, respectively. However, ADF content decreased from 281 to 267 g/kg and NDF contents decreased from 530 to 515 g/kg with increasing row spacing during the year 2002. In this study, hybrids showed distinct differences for crude protein, ADF and NDF contents in both years. Forage quality parameter including ADF and NDF of Pioneer 3163, TTM 8119 and Karadeniz Yildizi were higher than Arifiye hybrid.

An experiment was conducted to evaluate the dry matter yield and quality performance of Maralfalfa forage at six harvest intervals (HI; 40,50,60,70,80, 90d) at three dairy farms in northern Puerto Rico during the short day season. In the majority of the quality parameters under study, the HI of 40 and 50 days were significantly (P menor 0.05) superior to the other HI. Conversely, the dry matter yields from the above mentioned intervals were (P menor 0.05) inferior to those obtained with HI of 70, 80 and 90 days. The 50 and 60 day HI did not differ significantly (P > 0.05) in dry matter yield. The HI of 50 days yielded forage of a quality not very inferior to that of the 40 days (ex., % crude protein 19.1 vs. 16.0), but its dry matter yield was nearly three times higher (P menor 0.05) (3,000 vs. 8,607 kg/ha). The simple regression equations of in vitro digestibility of dry matter and of neutral detergent fiber vs. HI showed a digestibility loss of 5.0 and 6.0 percentage points for each 10 days increment in harvest interval, as the values decreased from 84% and 74% at HI 40 d, to 60% and 45% at HI 90 d, respectively.

ABSTRACT The objective of this work was to determine the factors of soil water availability (FSWA) that result in the highest agronomic performance of irrigated forage sorghum, with no changes in the plants' chemical-bromatological composition. The experiment was conducted at the Montes Claros State University, Janaúba campus, MG, Brazil, in a Typic Quartzipsamment (Neossolo Flúvico Psamítico - Embrapa) with 59 mm of soil water storage capacity in the 0.0-0.3 m layer, under drip irrigation. A randomized block design with four replications and a split-plot arrangement was used, consisting of five FSWA (f0.2 = 0.20; f0.35 = 0.35; f0.5 = 0.50; f0.65 = 0.65, and f0.8 = 0.80) in the plots and two simple forage sorghum hybrids (Volumax® and BRS-655) in the split-plots. The evaluations were based on fortnightly measurements of plant height, plant transversal diameter, number of leaves per plant, leaf area index, relative chlorophyll content, stem diameter, panicle length, dry matter yield, water use efficiency, crude protein, mineral matter, acid detergent fiber, neutral detergent fiber, and lignin. The FSWA of 0.20 and 0.35 increased dry matter yield and plant height of the two evaluated sorghum hybrids. The Volumax hybrid presented more crude protein content and acid detergent fiber. The evaluated FSWA did not change the chemical-bromatological composition of the sorghum hybrids.

The objective of this study was to evaluate the effect of planting alfalfa (Medicago sativa L.) with- and without cover crops on forage dry matter yield and nutritive values of alfalfa in Kansas, USA. In the first production year 2014, dry matter yield of mono-culture alfalfa appears to be compatible or even higher than planting with certain species of winter annual forages as a cover crop. Alfalfa planted with a combination of four different multi-species winter annual forages such as oats (Avena sativa L.), oilseed radish (Raphanus sativus L.), annual ryegrass (Lolium multiflorumL.), and turnip (Brassica rapa L.) had the highest dry matter yield of alfalfa in 2014.Dry matter yield of alfalfa in 2nd production year 2015 was similar to alfalfa + oats and alfalfa + oats + oilseed radish + annual ryegrass + turnip or significantly higher than alfalfa planted with annual ryegrass, oilseed radish, and turnip together. Based on two year of data in 2014 and 2015, the highest alfalfa yield occurred when alfalfa was planted with a combination of oats, oilseed radish, annual ryegrass, and turnip. The lowest dry matter yield of alfalfa occurred when alfalfa was planted with annual ryegrass.No significant differences in crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF) were found when comparing alfalfa monoculture with alfalfa + oats, alfalfa + oilseed radish, alfalfa + oats + oilseed radish + annual ryegrass + turnip, and alfalfa + turnip treatments. When considering both dry matter and nutritive values of alfalfa, planting alfalfa with cover crops appears to be compatible or better practice than planting alfalfa monoculture.

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.

An experiment was conducted to evaluate the dry matter yield and quality performance of Maralfalfa forage obtained at six harvest intervals (HI; 40, 50, 60, 70, 80, 90 d) on three dairies in northern Puerto Rico during the long day season. The 40-day harvest interval was significantly (P < 0.05) inferior in dry matter yield to those of 60, 80, and 90 days; no significant (P < 0.05) differences in yield were observed among intervals of 40, 50 and 70 days. The 40-day interval showed the highest forage quality as indicated by crude protein content, digestibility in vitro of dry matter and neutral detergent fiber, and estimated net energy, index of relative forage quality and theoretical milk production. Although significant (P < 0.05) differences were observed in some of these criteria between 40- and 50-day harvest intervals, the latter maintained a good nutritional value in contrast to drastic losses in quality observed with the longer harvest intervals under study. The simple regression equations between digestibility in vitro of dry matter and of neutral detergent fiber versus harvest interval showed a decrease in digestibility of 2.7 and 3.0 percentage points for each additional 10 days of harvest interval, respectively.

ABSTRACT The objective of this study was to evaluate the nutritive value of sugarcane silage with or without inoculation with P. acidipropionici or L. buchneri, over three fermentation periods. The experimental design was completely randomized in a 3 x 3 inoculant by fermentation period factorial arrangement (without inoculant, inoculant 1, inoculant 2; x three fermentation periods, 10, 60, 90 days). Values of pH, dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM) and lignin were determined and in situ DM degradability profiles were modelled for parameters a, b and c, potential degradation (A) and effective degradability (ED). The 90 day fermentation yielded a lower pH for both inoculants. There was an interaction between inoculant and fermentation period (P < 0.05) for DM content, with a reduction in silage DM without the additive at 90 days. The CP, HEM, ADF and lignin contents of sugarcane were not influenced by the treatments. The addition of P. acidipropionici provided the lowest NDF content at 10 days and presented a higher fraction a, potential degradation and ED. At 60 days, there was no variation in soluble fraction, the control silage showed a higher fraction b, higher potential degradation and ED. At 90 days of fermentation, L. buchneri silages presented a higher fraction a, degradation rate and DE and a higher b value was obtained in the silage without inoculant. Inoculants are effective in maintaining the silage DM content and nutritional value during prolonged fermentation periods.

An experiment was conducted to evaluate the effect of growth, biomas yieds and nutritive value of Lablab purpureus, Centrosema pubescens and Mucuna pruriens under rain fed condition in Yola, Adamawa State, Nigeria. The field experiment was laid in a randomized complete block design with the plot divided into three main plots and replicated three times measuring 5x5m with inter and intra row spacings of 0.5m. The five harvesting stages are 6, 8, 10, 12 and 14 weeks, respectively. The growth in height increases with stage of growth and declined with reduction in rainfall. Higher growth were recorded in T3 (3.8 -354.8cm) followed by T2 (2.96-260.20cm) and then T1 (1.50-213.00cm) and the results were presented graphically. The result of the chemical composition of all the legumes showed that the crude protein decreases with stage of growth from weeks 6 -14 (14.40, 12.26, 10.65-10.08, 6.79, 6.49) and ADF and NDF (25.20, 32.15, 27.35-42.13, 40.33, 36.50 and 32.20, 54.45, 47.00- 51.24, 63.53, 66.33), respectively. The biomass yields were significantly different (P<0.05) for all the legumes at different harvesting stages T1 (2744.53-3186.93), T2 (2696.47- 3006.70) and T3 (2843.73-3147.63). It is therefore concluded that legumes could best be harvested between weeks 10 and 12 when the yield and quality are at levels to sustain the animals both for maintenance and production.

he aim of this study was to evaluate fermentation and chemical characteristics and the in situ degradability of sorghum silages enriched with dried Leucaena. The experiment was conducted as completely randomized design with four treatments (0 - control silage, silage without leucaena; 10.0, 20.0, or 30.0% inclusion of Leucaena) and five replicates, totaling 20 experimental units. The inclusion levels of leucaena influenced (P 0.05), with all silages having values above 90%. Gas loss decreased (P < 0.05) as the level of leucine increased in sorghum silage. A linear increase was observed for dry matter (P ? 0.0001) and crude protein (P = 0.0008) contents in response to Leucaena inclusion. There was a linear (P < 0.05) linear effect on neutral detergent fiber, hemicellulose and acid detergent fiber. As leucaena inclusion levels increased, for each 1% inclusion a reduction of 0.179 was observed; 0.059 and 0.119% for the values of neutral detergent fiber, hemicellulose and acid detergent fiber respectively. The inclusion of leucaena influenced (P < 0.05) the increase of silage lignin levels, probably due to the higher lignin content of the legume. The soluble fraction (a) of the silages increased along with the Leucaena inclusion levels, with highest values observed at the inclusion of 20 and 30% of the legume, respectively. Potential degradation (A) increased linearly with the levels of Leucaena added to the silage; the highest value for this variable was observed at 30% inclusion. Effective degradability (ED) increased up to the inclusion level of 20% (46.77%). Degradation rate (c) decreased markedly with the use of 30% Leucaena. The use of the forage part of Leucaena dried for three hours leads to reduced gas production, increased dry matter and crude protein contents, and decreased fiber contents. The degradability of dry matter increases up to the inclusion level of 20%.
