Moreover, it was found that ewes in the LN photoperiod
were characterised by higher (p<0.
Cultivar production relation with temperature and photoperiod
in the greenhouse
For example, Gerard & Ruf (1997) observed that temperature influenced the biology of Anthrenocerus australis Hope (Coleoptera: Dermestidae), but other abiotic factors such as relative humidity and photoperiod
affect the life cycle to a similar extent.
The finding of a suitable photoperiod
for a particular species, can reduce social stress and increases: food intake, nutrient assimilation and specific growth rate (Fielder et al.
All of the results suggested that short photoperiod
can reduce body mass, body fat mass, increased food intake.
Air temperature and photoperiod
are meteorological elements that interfere with the development of grasses (Castro et al.
The experimental period started when the birds completed 21 weeks old, and at the beginning of the pilot phase (02/10) the natural photoperiod
contained 13:13h, passing through the winter solstice in the southern region of the country (06/23) with 10:03h, and at the end of the experiment (07/27) the natural photoperiod
was of 10:28h (Cotta, 2002).
Influence of photoperiod
and water availability on reproduction of male California voles (Microtus californicus).
Chickens subjected to a short/non-intermittent photoperiod
had the lowest body weight, body weight gain, feed intake, carcass weight, and fillet and tender weights when compared with those reared under long/continuous and regular/intermittent photoperiods
The SD photoperiod
treatments reduced the yield components and yield, but not affected significantly the yield components and yield under SD-12 h treatment compared with SD-8 h treatment.
Many studies have been conducted to see the influence of photoperiod
on the reproductive functions of male birds in view of their economic interest.
In this report, the combined effects of temperature and photoperiod
on broodstock conditioning of O.
