Effect of water addition on selective consumption (sorting) of dry diets by dairy cattle
No full textThe objective of this study was to determine whether
adding water to a dry diet would reduce sorting and
improve cow performance. Eighteen multiparous lac-
tating Holstein cows were used in a cross-over design
with 21-d periods. Treatments had the same dietary
composition and differed only by adding water (WET)
or not (DRY). Diets consisted of 10% alfalfa silage, 30%
hay (approximately 80% grass and 20% alfalfa), and
60% concentrate [dry matter (DM) basis]. Dietary DM
was 80.8% for DRY and 64.4% for WET. Both diets
contained 16.9% crude protein and 24.3% neutral deter-
gent fiber. Particle size was determined using the Wis-
consin Particle Size Separator on the as-fed diets. The
separator has five square-hole screens (Y 1 to Y 5 ) with
diagonal openings of 26.9 mm for Y 1 , 18 mm for Y 2 ,
8.98 mm for Y 3 , 5.61 mm for Y 4 , and 1.65 mm for Y 5 ,
and one pan. Sorting was calculated on a 60 ° C DM basis
(60DM). Predicted intake of Y i was calculated as the
product of 60DM intake (60DMI) and the 60DM fraction
of Y i in the total mixed ration for that screen. For DRY
and WET, actual 60DMI by screen expressed as a per-
centage of predicted intake was 61.4% vs. 75.2% for Y 1 ,
83.8% vs. 98.6% for Y 2 , 85.6% vs. 90.8% for Y 3 , 95.2%
vs. 96.0% for Y 4 , 100.1% vs. 101.9% for Y 5 , and 105.9%
vs. 102.9% for pan, respectively. Adding water did not
affect total DM intake (28.3 kg/d) or milk production
(41.3 kg/d). Neutral detergent fiber intake was 6.42 kg/
d for WET and 6.15 kg/d for DRY. Milk fat percentage
tended to be higher (3.41% vs. 3.31%) when cows con-
sumed WET vs. DRY. No differences in ruminal pH,
NH 3 , and volatile fatty acids were observed. Cows
sorted against long particles in favor of shorter particles
on both diets. Adding water to dry diets reduced sorting
and tended to increase neutral detergent fiber intake
and milk fat percentage

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
