Evaluating the use of Atriplex nummularia Hay on Feed Intake, Growth, and Carcass Characteristics of Creole Kids
Meneses,Raúl; Varela,Gabriel; Flores,Hugo;
Chilean journal of agricultural research , 2012, DOI: 10.4067/S0718-58392012000100012
Abstract: there is a surplus of atriplex nummularia lindl. grazing that can be used as animal feed. this material was harvested to assess the effects on intake, growth, and carcass characteristics of kids. atriplex replaced alfalfa hay (medicago sativa l.) in a proportion of 0%, 10%, 20%, 30%, and 40% for 60 creole kids weighing 13 kg and was assigned to the diets in a completely randomized design. the process was conducted from march to may. two males and two females were used from each group to evaluate individual nutrient intake. height at withers, thoracic diameter, and weight change were evaluated in all the animals. the carcasses of four females per group were evaluated. offered and rejected hay diet samples were chemically analyzed. atriplex hay crude protein (cp), metabolizable energy (me), chlorine (cl), and sodium (na) contents were 20.20%, 1.99 mcal kg-1, 4.78%, and 6.47% respectively. hemicellulose (hc), ash intake, height at withers, thoracic diameter, and carcass component, except for the kidney, were not different (p > 0.05) among treatments. over 20% of a. nummularia hay content in the diet caused an increase in mineral consumption (p < 0.05). total body weight gain decreased (p < 0.05) by adding 20% or more a. nummularia hay content in the diet. however, adding up to 20% of a. nummularia hay in the diet did not produce a negative effect and higher percentages decreased weight gains attributable to the high na and cl content.

Agricultural Sciences (AS) , 2011, DOI: 10.4236/as.2011.22019
Abstract: Soil microbial community structure is clearly linked to current plant species composition, but less is known about the legacy effects of plant species and agricultural management practices on soil microbial communities. Using microbial lipid biomarkers, we assessed patterns of com-munity-level diversity and abundance at depths of 0-10 and 10-25 cm from three hay (al-falfa/orchardgrass) and two corn plots in south ern Wisconsin. Principal components analysis of the lipid biomarkers revealed differential composition of the soil microbial communities at the two depths. Despite similar abundance of fungi, bacteria, actinomycete, protozoa, and total microbial lipids in the hay and corn at 0-10 cm, community structure differed with a sig-nificantly higher absolute abundance of arbus-cular mycorrhizal fungi and gram-negative bacteria in the hay plots. No significant micro-bial lipid mass differences were detected be-tween the two management regimes at 10-25 cm, but the proportional dominance of bacterial gram type differed with depth. These results indicate the potential for legacy effects of an-nual and perennial cropping systems manage-ment on microbial community composition and suggests the importance of considering past land-use when initiating long-term agroecolo- gical trials.

Abstract: The aim of the applied research project:“Forage evaluation by NIR spectroscopy” was to monitor the nutritive value of grass silage, corn silage and hay on family farms in Croatia over 6-month feeding in each of the two investigation years (from November 2003 to May 2004 and from November 2004 to May 2005). In this paper the nutritive value of hay on 18 dairy farms over the second year of investigation and the comparison of the results with the first year was done. Extension service staff recommended dairy nutrition based on monthly silage analysis by NIRS instrument (Foss, Model 6500). The following parameters were estimated: dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), metabolizable energy (ME), water-soluble carbohydrates (WSC) and organic matter digestibility in DM (D-value). The average results show desirable DM content (873.30 g kg-1), high NDF (671.16 g kg-1DM), but low WSC (83.53 g kg-1 DM), CP (61.75 g kg-1 DM), ME (8.75 MJ kg-1 DM) and D-value (58.33%). Great variations were observed for CP (40-133 g kg-1 DM), ME (6-11.7 MJ kg-1DM), WSC (21-160 g kg-1 DM) and D-value (40-78%). Statistically significant differences (P<0.05) among family farms were recorded for CP (P<0.05) that varied from 40-112.4 g kg-1 DM. No statistically significant differences were observed in the investigated parameters between the first and the second year of the investigation.
