AbstractTemperate grass and legume yield and quality are markedly reduced during hot, dry summer months in the southern USA; therefore, browse species could add feed options for small ruminants during this season. Our objective was to compare total biomass yield and forage nutritive value of two browse species, leguminous bristly locust (Robinia hispida) and smooth sumac (Rhus glabra), as well as a leguminous shrub known as sericea lespedeza (Lespedeza cuneate), during summer months (June, July, August and September). Plants were sampled monthly during growing-seasons in 2012 and 2013 to determine biomass yield (foliar, shoot, and total above ground) and foliar nutritive value [crude protein (CP), acid detergent fiber (ADF), acid detergent lignin (ADL), and condensed tannins (CT)]. There was a species × harvest time interaction for foliar biomass yield (P = 0.0125). This interaction was likely due to low yield in June for bristly locust compared with sericea lespedeza and smooth sumac, but in all other months (July, August, and September) yields were similar for each species. Bristly locust had the highest CP (16.9%), followed by sericea lespedeza (14.8%), and smooth sumac (12.3%). Acid detergent fiber and ADL were similar between bristly locust (ADF 38.5%; ADL 24.1%) and sericea lespedeza (ADF 38.4%; ADL 23.1%), but was lower for smooth sumac (ADF 22.1%, ADL 6.3%; P < 0.05). Condensed tannins, an anti-nutritive yet anti-parasitic phenolic compounds, were highest in smooth sumac, intermediate in bristly locust, and lowest in sericea lespedeza. Plant foliar percentage (ratio of foliar to shoot mass), was highest in smooth sumac (55.1%), followed by sericea lespedeza (47.7%), and bristly locust (42.6%). Overall, smooth sumac had the highest foliar biomass and lowest ADF and ADL; however, this species had the lowest CP and highest CT. Consequently, average foliar biomass yield of all three browse species in our study far exceeded forage yield from dominant forage species [tall fescue (Schedonorus arundinaceus) and bermudagrass (Cyanodon dactylon)] in this region and may provide high-yielding, low input, anti-parasitic fodder for small ruminants during this period in the Southeastern U.S.

Normalised Difference Vegetation Index

This study was conducted to investigate the potentials of normalised difference vegetation index (NDVI), nitrogen (N) concentration (%), and N content (g/plant) of whole maize plant to estimate yield and nutritive value of hybrid forage maize. Hybrid forage maize was grown with two rates of pre-sowing fertiliser N (0, 135 kg/ha) and three rates of post-sowing fertiliser N (0, 79, 158 kg N/ha) applied at the six-leaf stage. Data on the NDVI and N (% and g/plant) of maize were collected at 2-, 3-, 6-, 8-, 12-, 16-, 18-leaf stages and at harvest. Metabolisable energy (ME) content of the whole maize plant at harvest was estimated from in vitro digestibility. Simple, polynomial, and multiple regression analyses were conducted and only the best-fit models were selected. The 8-leaf stage was found to be the most effective stage for use of the NDVI in predicting biomass yield (R2 = 0.81), grain yield (R2 = 0.72), and N (%) (R2 = 0.92) of forage maize. Nitrogen (%) at the 8-leaf stage was also best related to biomass yield (R2 = 0.88). Multiple regressions at the 3-leaf stage increased the coefficient of determination for both biomass yield and grain yield (R2 = 0.77) over the relationships obtained from N (%) of the whole plant at 2- or 3-leaf stage. The NDVI and N (%) of the whole plant at 8-leaf stage were the best predictors of yield, but failed to predict ME content of the hybrid forage maize. Multiple regression models at the 3-leaf stage were almost as effective as the NDVI and N (%) of whole maize plant at the 8-leaf stage in predicting biomass and grain yield of forage maize.

The present study evaluated the chemical composition and in vitro ruminal digestibility of napier Pakchong 1 silage combined with maize cob and husk in different ratios. The napier Pakchong 1 grass was harvested at 45 days of maturity. The napier Pakchong 1 grass was ensiled with maize cob and husk at ratios of 1:5, 1:10 and 1:15. Three rumen fistulated Thai native cattle (White Lamphun cattle) with an average weight of 154 ± 4.7 kg were used to determine ruminal digestibility by in vitro gas-production technique. Gas production was recorded after incubating for 2, 4, 8, 12, 24, 48, 72 and 96 h. The microbial biomass yield was determined after incubating for 24 h. DM, NDF and ADF of maize cob and husk mixed with napier Pakchong 1 silage declined by increasing the proportion of napier Pakchong 1 grass, while gas production after 4–10 h of incubating maize cob and husk mixed with napier Pakchong 1 grass increased by increasing the proportion of napier Pakchong 1 grass. The metabolisable energy, organic matter digestibility and microbial biomass yield did not differ among the different ratios. The results of the study suggested a recommended ratio of maize cob and husk to napier Pakchong 1 grass of 1:10. The ensiling fermentation increased the proportion of protein in the roughage, which lead to increased in vitro gas production of roughage.

The success of maize + soybean intercrop depends on the plant arrangement. An experiment was carried out to evaluate different row arrangements on intercrop forage yield, silage quality and maize grain yield in relation to maize as a sole crop. The experiment was set up with a randomized complete block design with eight row arrangements between maize and Soybean. Maize biomass yield among crop arrangements were similar, although, lower than the maize sole crop. On the other hand, these treatments showed higher soybean biomass yield, which in turn increased silage crude protein and crude protein yield per unit area. Maize thousand grain weight, grain yield per plant and per area was affected by the intercrop arrangements. The use of two corn rows + two soybean rows (2M+2S-30 cm) and four corn rows + four soybean rows (4M+4S-30 cm) showed higher crude protein yield per area associated with similar maize grain yield in relation to the sole maize crop. In conclusion, alternating four maize rows with four soybean rows was the optimum row ratio in maize + soybean intercrop, though this needs to be further confirmed by more trials.

The aim of this paper is to study the chemical composition of a green fodder used in laying hens feeding raised in ecological system; organic fodder being an important condition to obtain organic eggs for consumption. In order to evaluate the chemical composition variations of the green fodder throughout the year, there were taken plants samples in three different vegetation stages (May, September and October). To each period, were done 5 determinations for the following indicators: dry matter - DM (%), ash - Ash (%), crude protein - CP (%), ether extract - EE (%), crude fiber -CF(%), nitrogen free extract - (NFE%) calcium � Ca(%), phosphorus - P(%), magnesium - Mg (%), natrium -Na(%). And also, were analyzed the relevant indexes for the organic production: lead -Pb (mg/kg DM), cadmium - Cd (mg/kg DM), cooper -Cu (mg/kg DM), zinc - Zn (mg/kg DM) nitrites (ppm), nitrates (ppm), pesticides. After analysis, it was noticed that dry matter, minerals, organic matter and protein content varied very significantly between the first period and the third (p �0.001), while the fat content, crude fiber and nitrogen free extract did not register significant differences (p �0.05). Regarding the minerals elements analyzed, P and Mg differed significantly distinctly between the first and the last analyzed period. The content of green fodder in Pb, Cd, Cu and Zn was below the limits allowed by current legislation. The analyses for pesticides have highlighted the lack of them in the fodder. The quality parameters of the analyzed green fodder, expressed through levels of pollutants such as heavy metals, nitrites, nitrates, pesticides, allow us to notify that the green fodders achieve the conditions necessary for organic production.

Lucerne is an important legume forage grown worldwide due to its high nutritive value, yield potential, quality and survival under highly contrasting environments. Estimation of genetic diversity in germplasm is an important criterion in breeding programme and is done based on phenotypic characters, biochemical and molecular markers. Thirty one accessions of Lucerne collected from Maharashtra and Gujarat were evaluated for morphological, yield characters, molecular markers and were compared with national check RL-88. The diversity analysis of morphological and yield characters indicated wide range of variation within the accessions. The accession RLG 08-1 recorded significant differences for plant height, number of tillers per plant, internodal length, green fodder, dry matter and crude protein yield (P 0.05) over RL-88. Green fodder yield was significantly correlated with plant height (0.72**), no. of tillers per plant (0.71**) and internodal length (0.71**). Dry matter yield was found significantly correlated with plant height, no. of tillers per plant, internodal length and crude protein yield (0.70**, 0.69**, 0.70** and 0.99**). Leaf stem ratio was not linearly correlated with green fodder, dry matter and crude protein yield. Principal component analysis (PCA) demonstrated that the first two PCs contributed to 93.7% of total variance among the accessions. The accession RLG 08-1 was found superior among all the accessions. Thirteen Inter Simple Sequence Repeats (ISSRs) markers showed 82.8% polymorphism. The dendrogram revealed slight geographical structuring and RLG 08-1 was found genetically distinct from other accessions.Mantel correlation was not observed between morphological and yield characters as well as molecular markers.
