Mothers demonstrate a unique ability t...
متن کاملGenetic aspects regarding piglet losses and the maternal behaviour of sows. Part 2. Genetic relationship between maternal behaviour in sows and piglet mortality.
The aim of the study was to analyse the genetic background of different traits to characterise the maternal behaviour of sows and to evaluate the relationship to different causes of piglet losses - increasing piglet survival due to higher maternal abilities of the sow. A total of 1538 purebred litters from 943 German Landrace sows in the year 2004 were available for data analysis. Around 13 971...
متن کاملMaternal behaviour and lamb survival: from neuroendocrinology to practical application.
Parental care promotes offspring survival and, for livestock species, this care is provided solely by the mother. Maternal behaviour in the sheep has been exceptionally well-studied compared with other species and many of the underpinning biological processes leading to the expression of maternal care are known. In this review the current state of play with regard to the biology of maternal car...
متن کاملFeed Conversion and Feeding Behaviour in Laying Hens
T_e high proportion of feed costs in total operating expenses (1,2,6) indicates that the utilization of feed by the birds is closely related to the profitability of >oultry operations. The relationship between feed conversion (expressed as a ratio between weight units of feed consumed per weight unit of product) and profitability (defined as an increment .of total income over total costs) is es...
متن کاملFeatured Articles in This Month’s Animal Behaviour
Sir Francis Galton famously demonstrated that, by combining the individual estimates of people guessing the weight of an ox at a country fair, one could arrive at an estimate that was considerably more accurate than any one individual’s guess. He named this effect the ‘vox populi’ and, since then, there have been many other demonstrations of ‘the wisdom of the crowds’ (for an excellent review, ...
