Analysis of daily activity patterns identified no between-group differences regarding the time allocated to feeding (two-way ANOVA with factors sex and breeding status: F3,32 = 2.76, p>0.05), but it did show significant differences amongst groups regarding locomotion (F3,32 = 8.32, p<0.05) and resting (F3,32 = 7.37, p<0.05).
We analyzed several different ratios RF:(1 − RF) between feeding-ground catch and spawning-ground catch, (6b) where RF is the proportion of the total catch that is allocated to the feeding grounds.
Half of both the infected and the control populations were randomly allocated to two feeding treatments with either P-sufficient algae or with P-limited algae, resulting in four replicate populations for each of the parasite-feeding treatment combinations (see Additional file 1 for schematic representation).
Upon confirmation of mating by the appearance of a semen plug on the cage floor, the rats were allocated to be fed (ad libitum) isoenergetic diets containing 18% protein (control, n = 8) or 9% protein (LP, n = 16), as described previously [27].
Thirty-one pregnant Scottish Blackface ewes carrying twins were randomly allocated to groups fed either a control protein (CP) diet (n=15) providing adequate protein from d 0 to 65 gestation (term ∼147 d), or a protein-restricted low-protein (LP) diet from d 0 to 65 gestation (n=16).
Ten 4 to 5-month-old heifer calves were allocated to 2 feeding groups, LO or HI, to obtain growth rates of 400 g/day or 900 g/day.
For dry matter intake evaluation, cows from both treatments were randomly divided in 5 groups of 8 cows each, and allocated to 8 individual feeding stations for 3 d.
Studies on European robins (Erithacus rubecula) demonstrate a significant tradeoff between time allocated to singing and feeding: individuals who devoted more time to singing often suffered the greatest energy storage losses (Thomas et al. 2003), and comparative studies also show that species with higher metabolic rates have decreased song outputs (Read and Weary 1992).
Each animal was randomly allocated to four diets fed in four successive 28-days periods, so that a total of 16 diets were fed (six ewes per diet).
In the first part of this study (pH monitoring), subjects were randomly allocated to two groups: fed with a high-pectin diet [enteral formula: pectin liquid = 2 1 (v/v ], or a low-pectin diet [enteral formula: pectin liquid = 3 1 (v/v)].
The patients allocated to the early feeding regimen (group B, 47 patients) began clear fluids on the first postoperative day.
