The study was to conduct to evaluate the chemical composition and nutritive values of feedstuffs (forages and concentrate mixtures) used for dairy goats nutrition in Vojvodina. Samples were collected from six farms, including one organic farm. The results showed that the relative feed values of analyzed forages were in the range of good, medium to lower quality. Average protein content from lowest to highest for investigated forages was: corn silage (Zea Mays) (65.37-82.57g kg??DM), alfalfa haylage (Medicago sativa L.) (159.99-184.17g kg??DM), pasture (185.30g kg?? DM), and alfalfa hay (Medicago sativa L.) (167.48-203.60g kg??DM). The non-fibre carbohydrates and protein content most varied in organic hay samples (cv: 29.25% and 19.09%, respectively). Generally, feedstuffs used in organic nutrition, including organic concentrate, were of lower nutritional quality and moreover contained higher amounts of crude fibre and lignin. Especially, a high source of variation was observed in investigated concentrate mixtures for the crude protein content (p<0.0001), ranged from 135.32 to 209.87g kg??DM. Corn silages also varied substantially in their chemical composition and significant difference (p<0.05) was observed in regard to acid detergent fibre (ADF) and lignin content (ranged: ADF: 242.20-319.24g kg??DM; ADL: 27.98-52.54g kg??DM, respectively). Furthermore, pasture contained the most soluble materials during May and June and their content was related inversely to crude fibre amount. This survey highlights that investigated farms still pay insufficient attention to the quality of the feedstuff. For the development of intensive goat farming, greater emphasis should be placed on using higher quality feedstuffs, as well, standards for feed quality must be considered and established.

The aim of the research was to determine the forage yield and quality of thirty alfalfa (Medicago sativa L.) genotypes. Plots were established in 2014 in Isparta, Turkey, in a randomized complete block design with 3 replicates. Five cuttings were done during the 2015, 2016 and 2017. The dry matter yield (DMY), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL) and relative feed value (RFV) were determined. According to the three years average results, significant differences were determined for all parameters. Alfalfa genotypes viz., Cay-1, Cay-2, Keciborlu-1 and Keciborlu-3 were selected for alfalfa breeding program due to their superior yield and quality features.

Medicago Sativa L

The effects of cultivars, date and rate of seeding on the yield and quality of alfalfa (Medicago sativa L.) seeded at the end of summer and harvested the year after was studied from 1971 to 1975 on a Kamouraska clay. Seeding in early August gave the best results; seeding should not be carried out after mid-August. Differences between cultivars were more important on the third than on the first cut. Aftergrowth was an important factor on yield during the first year of harvest. Seeding rate did not always affect the yield, but the 6,7 kg/ha rate yielded less than the 13,4 kg/ha rate at the first cut and when the cuts were summed. The combined effects of the three factors studied indicates the importance of the seeding date on the height, cover and yield of alfalfa. Digestibility and crude protein content of the dry matter were affected more by seeding dates than by cultivars. The effect of cultivars on quality was variable and seeding rates had no effect. The variation in forage quality may be attributed to a difference in maturity of the plant at harvest, rather than only to the factors studied.Key words: Medicago sativa L., cultivar, date, rate, yield, quality

Two Populations

The nutritional quality of lucerne (alfalfa, Medicago sativa L.) plants correlates positively with the presence of multifoliolate (MF) leaves. Using phenotypic recurrent selection, we developed populations with an increased percentage of MF expression from 6.7% in the original population (C0) to 77.7% in the fourth cycle (C4). The effect of selection on genetic diversity within and among populations was evaluated. The populations C0 and C4 were represented by 40 plants genotyped by using 25 simple sequence repeats (SSR). The number of alleles per locus was large in both C0 and C4, averaging 6.28. The within-population genetic diversity (HE) overall estimation was 0.723 for C0 and 0.726 for C4, the absence of significant difference between the two populations indicating that the genetic diversity was as large in C4 as in C0. The Nei’s population differentiation (GST) overall estimation was 0.013, meaning that only 1.3% of the total genetic diversity was between populations and 98.7% was within populations. An efficient selection process was conducted without any increase in inbreeding or genetic drift.

Genotype by environmental interactions in lucerne (Medicago sativa L.) present considerable challenges when selecting an appropriate cultivar for a particular location and farming system. Data on the yield and persistence of a range of lucerne cultivars and experimental lines grown in two Tasmanian environments, Forth (41.20°S, 146.27°E, Red Ferrosol soil, under cutting with high fertiliser inputs, i.e. a high yield potential environment) and Cranbook (42.00°S, 148.03°E, Red Ferrosol soil, under grazing with low fertiliser inputs, i.e. a low yield potential environment) were examined using winter activity class as the experimental factor. At Forth, winter-dormant lucernes were the lowest yielding genotypes. In contrast, at Cranbrook, highly winter-active genotypes had lower plant persistence and dry matter yield than winter-dormant genotypes. Modified joint linear regression analysis showed that in a cool temperate climate, winter-dormant genotypes are more suited to a low yield potential environment, whereas highly winter-active genotypes are adapted to a high yield potential environment. Both the semi-winter-dormant and the winter-active genotypes were adapted to all environments. The dry matter yield of winter-dormant and highly winter-active genotypes was most sensitive to environmental conditions in winter and spring, while performance of all cultivars and experimental lines was most stable over summer.

Medicago Sativa L

Boron (B) is an essential micronutrient for plant reproductive growth and seed setting. A better understanding of the reasonable application rate of B could provide guidelines for improving seed yield and quality. In this study, we used five B concentrations (0, 400, 800, 1200, and 1600 mg B L-1) to study the effect of foliar application of B on seed yield and quality of alfalfa (Medicago sativa L.) in northern China. Our results indicated that foliar B application increased the pollen number, pollen viability, and dry weight and B concentration of alfalfa reproductive organs. The effect of B on alfalfa seed yield can be attributed to affecting the number of inflorescence and the seeds per pod. Foliar application with 800 mg B L-1 made quantitative and qualitative improvements in seed yield and quality of alfalfa. These results help to explain the positive effects of B on alfalfa seed production.

Astragalus Cicer

Cicer milkvetch (Astragalus cicer L.) is a winter hardy, non-bloating forage legume. In southern Alberta and Montana, cicer milkvetch retains its leaves longer and maintains forage quality later in the season than alfalfa (Medicago sativa L.). Consequently, it has the potential to provide nutritious forage in the fall, at a time when pasture productivity and quality is limited, particularly in northern areas. The objectives of this study were (i) to compare the yield and quality of monocultures of cicer milkvetch and alfalfa over the growing season and (ii) to evaluate the long-term productivity of cicer milkvetch under Parkland conditions. Studies were initiated in Melfort, Saskatchewan in 1986 and 1987, and subplots were harvested monthly during the growing season in the 2nd to 6th years. Cicer milkvetch peak yields were similar to or higher than alfalfa in 7 out of 10 harvest years. Forage yield of alfalfa was generally higher than that of cicer milkvetch in early season harvests, but cicer milkvetch had similar or higher yields later in the season. As the growing season progressed alfalfa declined in leafiness and in in vitro dry matter digestibility whereas corresponding values for cicer milkvetch were higher than those for alfalfa in all harvests. The protein content of both legumes was similar for all harvests, declining with plant maturity. Cicer milkvetch maintained its production similar to alfalfa over the 6-yr period studied. Key words: Cicer milkvetch, Astragalus cicer L., Medicago sativa L., leaf retention, protein, digestibility
