ECONOMIC EVALUATION OF CROPSHARE AND CASH LEASE CONTRACTS IN SOUTH DAKOTA AND NEBRASKA

Factors influencing choice of share or cash rental leases for cropland are examined using a 1996 dataset containing 1071 lease contracts in Nebraska and in South Dakota. Logistic regression results indicate tenant's age, capital position, and relationship with landlord were more important than leased land use or crop management variables.Farm Management,

The Interface of Agricultural Land Leasing, Conservation, and Value Sets: An Analysis

This paper explores the hypothesis that tenants do not farm leased land with the same management integrity as their owned property. It assesses today\u27s agricultural land leasing practices in the context of sustainable resource management, specifically addressing the influences of human attitudes and value sets

Was Old Jules Right?: Soil Stewardship on Leased Land

In a country where more than 40% of the agricultural land is farmed by tenant operators, the question of how that land base is farmed becomes paramount In this study we examined soil erosion levels in relation to land tenure and surveyed tenant farmer practices and attitudes in Nebraska and South Dakota, We found leased land was farmed and maintained by tenants in an environmentally sustainable manner, Furthermore, we found no evidence to suggest variation from this norm due to type of lease, size of farm, type of farm organization, or landowner classification, While educational level and years of experience (age) contributed to soil stewardship practices, to a great extent tenant farmers in these Great Plains states farmed leased land in a conscientious manner to maintain their integrity and reputation in the community as being a good farmer, Landowners, as well as society at large, benefit from this perspective

Evaluation of genetic components in traits related to superovulation, in vitro fertilization, and embryo transfer in Holstein cattle

The objectives of this study were to estimate variance components and identify regions of the genome associated with traits related to embryo transfer in Holsteins. Reproductive technologies are used in the dairy industry to increase the reproductive rate of superior females. A drawback of these methods remains the variability of animal responses to the procedures. If some variability can be explained genetically, selection can be used to improve animal response. Data collected from a Holstein dairy farm in Florida from 2008 to 2015 included 926 superovulation records (number of structures recovered and number of good embryos), 628 in vitro fertilization records (number of oocytes collected, number of cleaved embryos, number of high-and low-quality embryos, and number of transferrable embryos), and 12,089 embryo transfer records (pregnancy success). Two methods of transformation (logarithmic and Anscombe) were applied to count variables and results were compared. Univariate animal models were fitted for each trait with the exception of pregnancy success after embryo transfer. Due to the binary nature of the latter trait, a threshold liability model was fitted that accounted for the genetic effect of both the recipient and the embryo. Both transformation methods produced similar results. Single-step genomic BLUP analyses were performed and SNP effects estimated for traits with a significant genetic component. Heritability of number of structures recovered and number of good embryos when log-transformed were 0.27 +/- 0.08 and 0.15 +/- 0.07, respectively. Heritability estimates from the in vitro fertilization data ranged from 0.01 +/- 0.08 to 0.21 +/- 0.15, but were not significantly different from zero. Recipient and embryo heritability (standard deviation) of pregnancy success after embryo transfer was 0.03 (0.01) and 0.02 (0.01), respectively. The 10-SNP window explaining the largest proportion of variance (0.37%) for total structures collected was located on chromosome 8 beginning at 55,663,248 bp. Similar regions were identified for number of good embryos, with the largest proportion of variance (0.43%) explained by a 10-SNP window on chromosome 14 beginning at 26,713,734 bp. Results indicate that there is a genetic component for some traits related to superovulation and that selection should be possible. Moreover, the genetic component for superovulation traits involves some genomic regions that are similar to those for other fertility traits currently evaluated.Agriculture and Food Research Initiative Grant from the National Institute of Food and Agriculture - 2013-68004-20365United States Department of Agriculture (USDA) USDA Agricultural Research Service - 1265-31000-096-00Southeast Milk Checkoff Progra
