This book was released on 2002 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two grazing systems were evaluated over three years to compare the amounts of hay fed, cow weight and condition score changes, growing animal production, and effects of management systems on the mass and nutritive value of forages. In a minimal land (ML) grazing system, replicated 8.1-ha smooth bromegrass-orchardgrass-birdsfoot trefoil (SB-OG-BFT) pastures were rotationally stocked with six spring-calving cows and calves. Excess forage was harvested as first-cutting hay, then the entire area was rotationally stocked the rest of the season. At termination of summer grazing, cows were fed hay in a drylot. In the year-round (YR) grazing system, 8.1-ha SB-OG-BFT, 6.1-ha smooth bromegrass-red clover (SB-RC), and 6.1-ha tall fescue-red clover (TF-RC) pastures were stocked with six spring-calving cows and calves, 12 stocker animals (previous season's calf crop) and six fall-calving cows. First-cutting hay was harvested from TF-RC and SB-RC pastures simultaneous to the ML system. Second-cutting forage was strip-grazed by cows, while stocker animals remained in SB-OG-BFT pastures. Stocker animals were removed from pastures and finished and cows were again stocked in SB-OG-BFT pastures, while forage was allowed to accumulate in TF-RC and SB-RC pastures. During winter, spring-calving cows sequentially strip-grazed corn crop residue fields and stockpiled SB-RC pastures. Simultaneous to initiation of corn crop residue grazing, fall-calving cows with calves strip-grazed stockpiled TF-RC pastures. Hay was supplemented during winter when weather conditions limited grazing. Fall-calving cows had greater (P [Less than or equal to symbol] 0.03) body condition scores at all production stages except post-breeding (P = 0.13) and post-weaning (P = 0.53) compared to either group of spring-calving cows. Total growing animal production was 27 kg/cow greater (P = 0.01) from the YR grazing system than the ML grazing system. The amount of hay fed in the ML grazing system was 896 kg DM/cow-stocker pair greater (P

This book was released on 2021 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the conversion of perennial pasture and hay land to cropland in the western corn belt region, alternative methods of cow/calf management are being used to decrease reliance on perennial forages. These include grazing corn residue and feeding cow/calf pairs in confinement. Previous research has shown that limit-feeding a diet of low-quality forage and energy-dense co-products to cows in confinement is cost effective. However, this strategy may limit the intake of the young calf and thus their performance. A study was conducted to evaluate the impacts of two alternative calf management strategies when pairs are in confinement, early weaning or creep feeding. The results suggest that providing a separate creep diet containing higher quality forage to the calf is a cost effective option as opposed to keeping cows and calves as pairs providing the limit fed diet containing low quality forage, or weaning calves early and feeding the cow and calf separately. Winter grazing of corn residue is a common practice, whereas grazing into spring is rare due to concerns about soil compaction and negative effects on subsequent crop yield. A study was conducted to evaluate the impacts of spring grazing and stocking density when targeting a grazing rate of consumption of 50% of the leaf and husk. The results suggest that grazing in the spring when the soil is thawed and wet results in negligible compaction. Increased stocking density in the spring when grazing corn residue does increase surface roughness and soil penetration resistance, but these effects were minimal. In fact, subsequent soybean yield was increased in a high yielding irrigated field due to grazing at both a normal and high stocking density in the spring. Combining confinement of cows with grazing residue may be a solution to maintain cow herds without utilizing perennial forages.

This book was released on 2019 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continuous and rotational grazing systems are two of the most frequently employed grazing systems in the western United States. Years of scientific evidence suggests that continuous grazing frequently outperforms rotational grazing in regard to cattle production. In this study we use economic data from a long-term USDA-ARS study in northern Colorado to determine if there are profit differences that may influence a producer’s decision to adopt rotational grazing. More specifically, we evaluate the costs that are expected to differ between the two systems (fencing and water infrastructure, and labor) over a suite of initial ranch conditions (contiguous vs non-contiguous ranches, grazed either continuously or rotationally). The livestock weight gain data was used with 20-year cattle market data for Colorado to calculate annual revenues using a model free of inter-annual market effects. Our results indicate that the additional infrastructure required to convert from a continuous to a rotational grazing system makes rotational grazing a financially infeasible option without cost share assistance. However, rotational grazing results in lower labor costs due to the increased stocking density of the herd. We also find that contiguous pasture ranches are significantly more profitable than non-contiguous ranches, a finding that could be especially pertinent to beginning ranchers as well as those looking to expand their operations.

This book was released on 2012-03-26 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mediterranean area shows a great diversity of livestock systems, depending on local resources and traditions, but also on the networking space where informational resources are available for producers. During the last decades, a lot of innovations have been conceived or introduced in the Mediterranean area, allowing livestock systems to remain competitive. The book looks at two main issues: firstly, it gives an updated review on the main innovations that significantly changed the activities of livestock production in the Mediterranean area in the recent past. Secondly, the focus lies on the extent to which these innovations improve the efficiency, ensure the socio-cultural basis or reduce the environmental impact of livestock systems. One major finding is a new vision of innovating systems based on the distinction between regulated innovation (when aims are fixed) and innovative design (when aims are questioned). Innovations reported in the book are dealing with a set of concerns. They concern the production techniques, the work organization, the equipment and infrastructures, the collective features for selection, reproduction, feeding or sanitary devices. They also concern the local organization such as product labelling, new dynamics around local breeds, collective rules for supply basin or approaches of new products for new markets. More recently, some innovations focus on environmental impacts of livestock production, due to an increasing consciousness of those kinds of problems. In the final part of the book, a round table copes with a crucial question: are traditions in Mediterranean livestock activities to be considered an obstacle or a source of innovation? This book provides a set of updated information and knowledge useful for researchers, students, extension services and policy-makers in the field of animal science.
