Evaluating Hay Quality

One of the frustrations to nutritionists interested in the feeding value of roughage has been that with all their book knowledge and technical aids no dependable scheme they could devise would consistently rank forages in feeding value, while the dumb ruminant animal could unerringly detect differences in their nutritive values.-E. W. Crampton, 196

Hay Quality Evaluation

During the last few years there have been several developments related to hay quality evaluation and marketing. In this presentation I shall briefly review these and indicate some of the implications for producers, vendors, purchasers and users of alfalfa hay

Using Birdsfoot Trefoil in Kentucky Pastures

Birdsfoot trefoil (Lotus corniculatus L.) is an excellent pasture legume in the Corn Belt and in northeast United states . It has usually been considered too poorly adapted to Kentucky to merit trial by the farmers. Observations and grazing results in Woodford county during the last 14 years, however, indicate that this view is no longer valid. A grazing trial was established in 1954, with birdsfoot trefoil and Kentucky bluegrass as one of three mixtures used. Trefoil was seeded alone in the spring, and an excellent stand was obtained. Bluegrass was drilled in the established trefoil in September 1954. There were four 4-acre experimental pastures of trefoil-bluegrass and an additional 6-acre field which was used as a reserve pasture

Slide Stabilization With Gravel Trenches

A different method of slide stabilization using gravel trenches is described. The design, construction, and performance monitoring of the gravel trenches are discussed together with a history of the slide, description of the soils, and mechanism of failure. The applications and limitations of this method of slide stabilization are also evaluated

Some Observations and Comments on Birdsfoot Trefoil

Farmer\u27s Bulletin No. 2191, TREFOIL PRODUCTION FOR PASTURE AND HAY, was released by the U.S. Department of Agriculture in July, 1967. This publication noted that acreages of trefoil in the U.S. increased from 770,000 in 1957 to over 2 million acres in 1967. This bulletin is an excellent guide to kinds of trefoils, to the different varieties available, and to general production practices in obtaining stands and in managing this legume. It is stated in the bulletin that birdsfoot trefoil is not recommended south of a line drawn from the Nebraska-Kansas border to the east coast, except at higher elevations. (The very northern tip of Kentucky is about 70 miles south of the Nebraska-Kansas line.

Associations Between Temperamental Negative Affectivity and Parental Anxiety Across Childhood

Extant research suggests a link between child temperamental negativity and parental anxiety and depression. However, most studies focus on temperamental negativity generally, and over fairly short longitudinal time spans. The present study extended the time span well beyond immediate postnatal infancy and explored associations between specific child temperament dimensions, both positive and negative, and parental psychopathology. We expected positive relationships between temperamental negative affectivity and parental mental health problems, but an inverse relation involving temperamental effortful control. Data were collected on child temperament, and parental anxiety and depression, using a cross-sectional design and anonymous survey methodology across five child age groups: infancy (INF; 3 - 13 months, N ≅ 83), toddler (TOD; 14 - 36 months, N ≅ 94), early childhood (EC; 3 - 7 years, N ≅ 81), middle/late childhood (MLC; 8 - 10 years, N ≅ 31), and early adolescence (EA; 10 - 15 years, N ≅ 38). REDCap survey links were published on several dozen social media outlets and relevant listservs. Across all datasets, parental respondents primarily identified as white and female. Child gender distribution was approximately equal between girls and boys. We used the Rothbart family of instruments to assess temperamental negative affectivity and effortful control in each sample (i.e., IBQ-R Short Form, ECBQ Short Form, CBQ Short Form, TMCQ Standard Form, and EATQ-R Short Form, respectively). Parental anxiety was measured by the Generalized Anxiety Disorder Assessment (GAD-7), and parental depression was measured by the Patient Health Questionnaire-9 (PHQ-9). Associations involving child negative affectivity were generally consistent with expectations. Results indicated positive correlations between parental anxiety and child negative affectivity in 4 out of 5 groups (INF: r(83) = .25, p = .02; TOD: r(94) = .27, p = .01; EC: r(81) = .37, p \u3c .001; EA: r(39) = .57, p \u3c .001), and between parental depression and child negative affectivity in all age groups (INF: r(81) = .26, p = .02; TOD: r(91) = .22, p = .03; EAC: r(80) = .26, p = .02; MLC: r(30) = .42, p = .02; EAA: r(37) = .42, p = .01). Effortful control was negatively, but less robustly, correlated with parental anxiety (TOD: r(94) = -.22, p = .03; EAA: r(39) = -.44, p = .02) and depression (TOD: r(91) = -.29, p = .01; MLC: r(30) = .45, p = .01). Although we make no assumptions regarding directions of effect between child temperament and parental mental health, bidirectional influences seem likely. For example, parental mental health problems probably exacerbate temperamental negative affectivity, and temperamental negative affectivity probably exacerbates parental mental health problems. This study provides an important expansion of the timeframes of associations between parental mental health and child temperament
