Experience In Grazing Large Young-Cattle Herds In The "Lewitz" State Farm, Ulrich Scharfenorth
IGC Proceedings (1977-2023)
In the Lewitz, a region with a large share of grassland, an efficient centre of heifer raising with an annual output of 5,000 head was established with the help of our socialist State. Heifer production in the "Lewitz" State farm is being expanded on account of the positive experience gained. Industrialized heifer raising allows grazing and makes it economically advisable. The advantages of grazing can be adequately linked with the requirements of intensive young-cattle raising. Grazing herds of 200 to 500 head of young cattle puts higher demands on the herdsmen than indoor keeping in summer. This kind of grazing …

Young-Cattle Rearing Along Industrial Lines And Pasturing In The Gdr, H Kleiber, F Morchen, F Lemme
IGC Proceedings (1977-2023)
Young-cattle rearing along ind us trial lines involves a general increase ofrearing standards. When pasturing large herds of young cattle it is difficult to achieve high live weight gain. Factory-like milk production requires not only optimal live weight development of the heifers but also an excellent state of health of the animals' legs. The latter is achieved more easily through pasturing than by way of indoor rearing of the youngstock. The intensification of young-cattle rearing includes the intensification of pasture rearing as well. Young-cattle rearing along industrial lines brings up new problems to be solved by technological research workers.

Effectiveness Of Irrigated Pastures, Nikolai Gavrilovich Andreev
IGC Proceedings (1977-2023)
Irrigated pastures are of greatest relevance to stabilizing the general fodder situation, for reasons of the high yield and low cost of pasture forage. If irrigation and fertilization are provided, best yields may be expected from forage plant mixtures which consist of five species: three grasses and two legumes. Fertilizer application must be quantified, depending on the soil nutrient status and in conformity with agrochemical test results and soil maps. The use of slurry obtained from livestock farms is useful not only for higher pasture forage yields but also for better protection of ground water and surface water. Irrigated pastures …

Aspects Of Efficient Grassland Utilization By Concentrated Sheep Flocks, Hans-Joachim Gutsche
IGC Proceedings (1977-2023)
Pasture utilization by sheep and its adaptation to crop production along industrial lines is a main point of sheep farming and implies the concentration of sheep flocks. Electric fencing is increasingly employed in grassland utilization. Whole-day ration grazing with daily rotation is finding general acceptance. Avoiding unproductive driftways and utilizing natural activity periods for feed intake are major features that make this procedure so effective. Working-time expenditure of 0.19 man-minutes per sheep at a flock size of 1500 head was found to be the optimum value. Combination of three flocks provides the conditions necessary for work in groups and for …

Intensive Use Of Pasture By Sheep In Southland, New Zealand, A J. Harris, M J. Hickey
IGC Proceedings (1977-2023)
Production from pastures containing white clover is described for the southern region of New Zealand. An outline is given of a selfcontained grazing experiment in which district practice at a high ewe stocking rate is compared with a moderate rate with an induced high lambing percentage. Yields of animal products and pasture utilisation patterns are presented and these demonstrate advantages of fitting animal requirements as closely as possible to pasture production. Yield increases are possible from improved plant varieties and it is suggested that the incorporation of these into efficient animal systems will lead to further productivity increases.

Interrelationships Of Pasture Production, Pasture UtilizaTion And Animal Production From Grazed Pastures On Kangaroo Island, South Australia, P R. Gibson
IGC Proceedings (1977-2023)
Pasture dry matter production, crude utilization and availability data are presented for two treatments (annual- and perennial-based pasture) in a larger stocking rate experiment carried out on the Kangaroo Island Research Centre, South Australia. There was no significant effect of stocking rate on mean annual pasture production for the four-year experimental period although some within-season correlations (both positive and negative) were observed. The mean efficiency of wool production in relation to pasture production and rainfall increased with stocking rate up to 17 sheep/ ha highlighting the biological efficiency of high stocking rates on these pastures.

Possibilities Of Raising Grassland Yields And Sheep Production By Means Of Intensive Nitrogen Fertilization, Jozef Kvietok
IGC Proceedings (1977-2023)
Application, after every grazing cycle, of 40 and 80 kg of nitrogen per hectare of sheep pasture, respectively, raised pasture yields to several times the level achieved in the unfertilized control. The fertilized herbage contained larger quantities of nitrogen compounds, with a trend to further increase in the following years. In variant A (40 kg N/ha) conversion of fertilizer nitrogen into plant matter was more efficient. In variant B (80 kg N/ha) we found a better balance of herbage regrowth over the whole grazing season. The amount of animal products produced in the individual variants correlated with the quantity and …

Permissible grazing frequency was elucidated by comparing forage plant mixtures for their response to different regimes of use, with reference being made to variation in yields and in the percentage of sown legume components in the stand. In the absence of nitrogen-fertilized grass stands in the pasture, a mixture with white clover is recommended for five uses. For four uses it is more suitable to take mixtures with red clover or alsike clover, or with white clover as well, provided the availability of grass stands for early pasture use. Only three uses per season are permissible of alfalfa/ grass mixtures, …
