Land Changes

The quality and quantity of production from irrigated lucerne, chicory and red clover swards were compared over six years (30 November 1996 30 June 2002) on a Wakanui silt loam at Lincoln University. Mean annual yields from lucerne swards (21 t DM/ha) were 3.9 t/ha greater than chicory and red clover over five perennial regrowth seasons. Sown species gave 100% of dry matter (DM) production in the first regrowth season, but by the fifth season sown species gave 65, 55 and 0% of DM production for chicory, lucerne and red clover respectively. Utilised herbage had a similar metabolisable energy (ME) content for all three species (10.9 11.6 MJ/ kg/DM). The crude protein (CP) content of utilised herbage was also similar for lucerne and red clover (0.25-0.29 g/g DM), but chicory had a lower CP content (0.18 g/g DM). This combined with utilisation data to show lucerne swards provided 30% greater annual CP and ME intake for grazing stock than either chicory or red clover. This demonstrated the greater potential of lucerne to improve livestock production from high value land. Changes in lucerne herbage quality were also analysed within regrowth cycles to examine the influence of the time of grazing on CP and ME intake. The fraction of palatable lucerne herbage decreased linearly from 100% at 700 kg/ha standing DM to 57% at 4300 kg/ha standing DM. The CP and ME contents of the palatable fraction of lucerne herbage were always higher than the post grazing residual. This highlights the selective grazing of the stock, which consumed 80% of total CP and 70% of total ME for a crop of 4300 kg/ha standing DM. This grazing preference shows that delaying defoliation will not reduce potential stock production, unless stock are forced to consume the low quality stem in standing herbage.

Abstract This study highlights the effect of drought and ambient temperature on performance and herbage quality of legume monocultures and grass-legume mixtures. In a field experiment, the total dry matter yield, seasonal pattern of dry matter yield distribution, content of crude protein and crude fibre of monocultures of red clover and alfalfa and grass-legume mixtures were investigated during two consecutive dry years (2011-2012). Alfalfa cultivars Kamila and Tereza grown as monocultures or as mixtures with Festulolium braunii (cultivar Achilles) outperformed the red clover cultivars Fresko and Veles and provided a well-balanced total and seasonal dry matter yield during both years. Across all experimental years, crude protein content was significantly higher at alfalfa monocultures and mixture when compared with clover monocultures (P < 0.05). However, considerable lower content of crude fibre at clover monocultures in comparison with alfalfa ones was found. Responses of nutritive parameters of both legume species to weather variables were different. Crude protein content in red clover was independent of rainfall and temperature. In contrast, the crude fibre content correlated with temperature whereby the alfalfa monocultures showed stronger correlations (P < 0.05) than red clover monocultures.

Trifolium Pratense L

The objective of this study was to investigate the changes that take place in nutrient values of red clover (Trifolium pratense L.) cv K-27 at different stages of growth in the second and the third cut. The samples from different stages of growth: mid-bud stage, around 60% flowering and full flowering were investigated for crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), digestible dry matter (DDM), dry matter intake (DMI), relative feed value (RFV), total digestible nutrients (TDN), net energy-lactation (NEl), net energy-maintenance (NEm) and net energy-gain (NEg) content. Higher content of crude protein was found in the third cut (262.1 g kg-1 of DM) than in the second cut (260.8 g kg-1 of DM) in the first stage of development. TDN, DDM, DMI, RFV, NEl, NEm and NEg were calculated according to the appropriate equations adapted from common formulas for forages. The stage of plant development has a significant influence on the chemical composition and the relative feed value of red clover. The achieved results show that adequate maturity stage for cutting might be at mid-bloom stage, when crude protein content, NEl, NEm and NEg content are high.

The effects of temperature, water and nitrogen on pasture production of an 8 year old 'Wana' cocksfoot pasture were quantified at Lincoln University, Canterbury. The maximum dry matter (DM) yield was 22.0 t/ha/yr when neither water nor N were limiting. Crude protein yield of +N pastures was 3.2-4.2 t/ha/yr compared with 1.0 t/ha in -N pastures. Metabolisable energy averaged 178*103 MJ ME/ha/yr for the +N pastures compared with 69*103 MJ ME/ha/yr for -N pastures. Seasonal differences in pasture production were explained in relation to thermal time with 7.0 kg DM/oCd for N fertilised pastures and 3.3 kg DM/oCd when no N was applied. During periods of water stress, relative yield decreased at a rate of 1.4%/mm when the soils critical limiting deficit of 78 mm was exceeded.

To monitor seasonal changes in herbage quality, a lucerne-based pasture (Medicago sativa, Bromus willdenowii and Dactylis glomerata) was sampled in Argentina every 2 weeks for 28 months. The pasture was strip-grazed and samples were taken from the regrowth of a previously grazed strip, ready for regrazing, for which herbage mass was estimated with a calibrated rising plate meter. Each sample was sorted into dead and green components, and the latter subsequently separated into grass and lucerne, and then into lamina plus leaflet and stem plus pseudostem fractions. Similarly, at each sampling date, quantitative maturity indexes – mean stage by count and mean stage by weight – were applied to grasses and lucerne. Samples were also analysed for in vitro dry matter digestibility (DMD), crude protein (CP), fibre and non-structural carbohydrates. The dataset was divided into morphological, maturity and nutritional variables. Analyses of variance by season for both groups of variables were carried out using year as a block. Multiple regression analyses were performed for each season between maturity indices and predictors of herbage quality. DMD, and consequently metabolisable energy (ME), was significantly lower in the autumn and CP was lower in the summer compared with overall averages, which were consistently high throughout the year (overall average of 11.5 MJ ME/kg dry matter and 20.6% CP). The sward had a higher proportion of lucerne during summer and autumn, than winter and spring (averages 59.3 and 48.8%, respectively). The highest leaf : stem ratio (2.82) was during winter and the highest green content (97.5%) was during spring. Grasses had a higher mean stage by count and mean stage by weight during spring–summer, whereas lucerne had a higher mean stage by count and mean stage by weight during summer–autumn. Morphological and maturity estimates predicted satisfactorily the changes in the energy and fibre within season, but CP content was not well predicted in summer or winter. These results provide the basis for tactical grazing practices with further calibration.

Six Trifolium pratense L. cultivars, five diploid and one tetraploid, were grown in the lowland region (123 m altitude) and the mountain region (650 m altitude). Dry matter (d.m.) and green mass (g.m.) yield, stem height and leaf proportion were assessed from each of the three growing seasons. Chemical composition was assessed from the average samples of all cuts in the second year of the experiment. Greater green mass (54.14 t/ha) and dry matter yield (9.86&nbsp;t/ha), stem height (0.61 m), crude protein (157.6 g/kg), crude fiber (222.9 g/kg), crude ash (100.68 g/kg) and crude fat (30.09 g/kg) content were observed in the mountain region, compared to the lowland region (45.61 t/ha g.m. 8.92 t/ha d.m. 0.59 stem height, 156.38 g/kg crude protein, 216.6 g/kg crude fiber, 94.85 g/kg crude ash, 24.98 g/kg crude fat). The greater leaf proportion (47.2%) and nitrogen free extract content (420.13 g/kg) were observed in the lowland region compared to the mountain region (42.95% and 402.99 g/kg, respectively). A significant location &times; cultivar interaction was found for all investigated parameters except for leaf proportion.&nbsp;

In this paper, yield and quality of forage following species of forage legumes were evaluated with regard to precipitations: lucerne (Medicago sativa L.), red clover (Trifolium pratense L.), white clover (Trifolium repens L.), kura clover (Trifolium ambiguum M.), alsike clover (Trifolium hybridum L.) and birdsfoot trefoil (Lotus corniculatus L.). The trial was sown in the spring of 2008, evaluated in the period 2009–2011. Analysis of samples was performed with the apparatus NIRS 6500. Following parameters were evaluated: production of dry matter, energy concentration (NEL), contents of fibre and crude protein. The highest three year yield average was measured for lucerne (15.01 t.ha−1), followed by red clover group (9.3–11.8 t.ha−1). Kura clover gained the lowest yield (1.97 t.ha−1). The average crude protein contents (g.kg−1) were: lucerne 211.47, red clover group (184.3–194.8), white clover group (229.1–238.7) and birdsfoot trefoil (204.2). The obtained results indicated that lucerne responded at best to periods of drought. Although the production of dry matter decreased in periods of drought, the canopy of stands remained to be complete in contradistinction to white clover, which partly disappeared from the stand. Red clover and alsike clover disappeared from the stand during the trial.

Supplementary feeding of grazing dairy cows is often uneconomic, and whilst supplementation with silage (buffer feeding) can be worthwhile, this often leads to a depletion of winter forage stores. In this study, a mixture of brewers grains and treated straw was used as a supplement. Offered as a 1:1 mixture in the dry matter (DM), it is a purchased substitute for grass silage, having a similar cost, and similar metabolisable energy (ME) and crude protein (CP) contents. The high seasonality adjustments to milk price in mid-late season make supplementation potentially worthwhile.Experiments were carried out from April to September in 1988 and 1989, which had moderate and very low rainfall respectively. Each year 20 British Friesian cows which calved December to March (1988 experiment) and February-April (1989) were allocated at random to either treatment B or C. In B, the cows were offered a 1:1 mixture (DM basis) of brewers grains and NaOH treated chopped barley straw for 60 minutes after morning milking. In C, the cows received no supplement. Both groups were fed 1.0 kg/day of concentrates in the milking parlour. Due to the severe drought in 1989, concentrate feeding was increased to 5.0 kg/day for all cows during the last 4 weeks of the experiment. Also, urea-treated whole crop wheat was fed at a level of 2.5 kg DM/day during the last 7 days.

По результатам научных исследований, выполненных за ряд лет в растениеводстве и животноводстве, показана целесообразность интродукции в кормопроизводство Пермского края новой многолетней бобовой культуры эспарцета песчаного. По четырёхлетним наблюдениям (2012 2015 годы) в полевых опытах культура не уступала по урожайности кормовой массы традиционному для региона клеверу луговому, а по концентрации обменной энергии и сырого протеина в сухом веществе была на уровне клевера лугового и люцерны изменчивой, но в разы превосходила их по содержанию сахара. Сенаж это единственный вид зимнего корма, максимально сохраняющий обменную энергию, протеин, сахар, каротин, достаточно концентрированный, чтобы обеспечивать потребности высокопродуктивных животных. В 2018 году на Лобановском молочном комплексе ООО Русь в Пермском районе Пермского края были проведены научнохозяйственный и физиологический опыты по скармливанию сенажа из эспарцета песчаного голштинизированным коровам чёрнопёстрой породы. При использовании сенажа из эспарцета песчаного животные в сутки потребляли сухого вещества на 2,3 3,9 кг на голову больше по сравнению с группой, где в рационе было сено (контроль). В результате использования сенажа из эспарцета песчаного переваримость сухого вещества рациона у опытных групп животных была выше на 2,55 5,80 по сравнению с контрольной органического вещества на 2,54 4,14 . За учётный период научнохозяйственного опыта (120 дней) от коров опытных групп получено по 399327,2 и 414431,9 кг молока, что со средней степенью достоверности выше продуктивности животных контрольной группы (391045,4). По содержанию молочного жира и молочного белка преимущество достоверно также было за опытными группами. Затраты корма на 1 кг молока составили в контроле 0,74 энергетических корм. ед. (ЭКЕ), в опытных группах 0,71 и 0,69 ЭКЕ. Hungarian sainfoin was shown to be an effective perennial legume crop in the forage production of the Perm Territory. For 4 years (2012 2015) this crop produced forage mass, exchange energy and crude protein comparable to the ones of red clover and bastard alfalfa but exceeded them significantly in carbohydrate content. Haylage is the only type of winter forage that has sufficient concentrations of exchange energy, protein, carbohydrates and carotene, satisfying needs of highproductive livestock in nutrients. Haylage from Hungarian sainfoin was fed to Holstein BlackandWhite cows in the frame of experiments conducted in 2018. Cows consumed 2.3 3.9 kg more of dry matter (DM) with the haylage, compared to hay (control). Digestibilities of DM and organic matter were 2.55 5.80 and 2.54 4.14 higher than in the control group, respectively. For 120 days the experimental groups produced 3993 27.2 and 4144 31.9 kg of milk versus 3910 45.4 kg of the control one. The former also exceeded the latter in milk fat and protein contents. Fodder costs per 1 kg of milk amounted to 0.74 energy feed units in the control and 0.71 and 0.69 energy feed units in the experimental groups.

Using ileal digestible amino acids in feed optimising will intensify feed protein utilizing and decrease nitrogen excretion to the environment. The study determined the apparent ileal digestibility (AID) coefficients of amino acids in barley, wheat, oats, triticale, maize, and dehulled oats in the diets of 180 Ross broiler chickens (aged 24–35 days). The birds were fed semi-purified diets that contained grain as the sole protein source and chromium-mordanted straw as an indigestible marker. The AID coefficients of the nutrients were assessed using the slaughter technique, and the apparent metabolisable energy (AME) was determined using total excreta collection. The ileal digestibility of the dry matter and organic matter were the highest in maize. The AME of maize was higher than that of other cereals. The ileal digestibility of crude protein was higher in wheat than that in barley, oats and dehulled oats. The AME of wheat was similar to that of barley and oats but lower than that of triticale and dehulled oats. The amino acid AID was highest in wheat (0.86) and triticale (0.85) and lowest in oats (0.79) and barley 0.77). The average amino acid AID was 0.81 in dehulled oats. The threonine AID was the same in all tested ingredients. The lysine, methionine, and cystine AID coefficients were 0.81, 0.79, and 0.71 respectively for barley; 0.86, 0.84, and 0.38 respectively for oats; 0.87, 0.86, and 0.53 respectively for dehulled oats; 0.84, 0.90, and 0.66 respectively for maize; 0.89, 0.88, and 0.77 respectively for triticale; and 0.87, 0.85, and 0.71 respectively for wheat. Results indicated that AME –values of domestic grains (barley, oats and wheat) are in the same level. Especially, low AME value of wheat needs further investigation.;
