Flea species richness and parameters of host body, host geography and host ‘milieu’
TLDR
The results show that species richness of ectoparasites is affected little by parameters of the host body and to a greater extent by parameters related to the host environment.
Effects of solar radiation, dietary energy, and time of feeding on thermoregulatory responses and energy balance in cattle in a hot environment.
TLDR
It seems that a lowered body temperature in the morning is a physiological mechanism used by animals to prepare for the heat load that develops during the day and changing the time of feeding to the late afternoon could be beneficial to the animals in reducing their heat loads.
Acacia saligna as a fodder tree for desert livestock and the interaction of its tannins with fibre fractions
TLDR
It was concluded that Acacia saligna could not be used as a sole dietary source for small ruminants because of low intake and negative nitrogen balance, however, the tree might have a potential as a supplementary fodder due to its high crude protein content.
Sheep and goat milk in pastoral societies
TLDR
Sheep and goats raised by pastoralists are generally low-producing in terms of milk and offspring but are well-adapted to the climatic conditions and are relatively tolerant of local diseases.
Growth rate, total body water volume, dry-matter intake and water consumption of domesticated ostriches ( Struthio camelus )
Growth rate, total body water volume (TBW), dry-matter intake (DMI) and water consumption were determined in ostriches from hatching to 350 days at which time they weighed approximately 100 kg. A
Is a starving host tastier? Reproduction in fleas parasitizing food‐limited rodents
TLDR
The results suggest nutritional and/or energetic cost of host resistance, measured as host-mediated parasite fitness loss, as well as possible adaptive stress-induced immunosuppression, in fleas parasitizing underfed animals.
Tritiated water for estimating total body water and water turnover rate in birds.
TLDR
The use of tritiated water (TOH) to estimate total body water (TBW) and total water turnover rate was validated in chukar partridges and sand partridges to conclude that the TOH method provides accurate estimations of TBW and water turnover rates in birds.
Average daily metabolic rate of rodents: habitat and dietary comparisons
TLDR
The predictions in regard to desert and non-desert habitats were confirmed, and there is a non-significant trend in the predicted direction with respect to diet, although results are not in agreement with predictions.
The nutritive value of Acacia saligna and Acacia salicina for goats and sheep
TLDR
It is concluded that neither A. saligna nor A.salicina could be used as a sole food for small ruminants because of low intakes and negative nitrogen balances.
Fertility decline in aging roosters is related to increased testicular and plasma levels of estradiol.
TLDR
It is suggested that plasma levels of LH and testosterone in roosters are regulated by a negative feedback mechanism involving estradiol that is produced not only by the aromatization of testosterone in the brain but also by peripheral estradiola originating in the testes and that estradio has a major role in the decline in fertility in aging roosting.
