Suckling Behaviour of Piglets Affected by Body Weight and Sex
Piglet suckling behaviour has been extensively studied, but surprisingly, there are not many studies that specifically consider body weight and sex in this context. These two basic individual characteristics have been considered more as supporting data but not as main factors. Therefore, the objective of the present research was to examine the effect body weight on suckling behaviour of piglets during lactation separately by sex. The study comprised 14 litters with a total of 158 piglets (85 male, 73 female, litter size 6−15 piglets). Suckling behaviour was described in terms of suckling position (the teat at which the piglet suckled during suckling), suckling territory (the range two outermost suckling positions of the piglet encompasses) and sucklingstability (the tendency to suckle successively at the same position), and was observed in six periods: 0−3, 4−7, 8−10, 11−14, 15−21 and 22−32 days of age. In each period, piglets were also weighed. The udder was divided into three areas: anterior (1st-2nd teat pair), middle (3rd-5th teat pair) and posterior (6th-8th teat pair). Body weight affected suckling behaviour differently in male and female piglets (i.e., all traits in females, suckling stability only in males). The relative body weight of females decreased significantly from the anterior towards the posterior part. Heavy females (but not males) suckled considerably more frequently on the anterior area. Heavier piglets (male and female) established more stable suckling order. Suckling territory of males was quite large, but did not differ among body weight classes. Interestingly, light females visited significantly larger suckling territory than heavy females. The present results fill a gap in the otherwise broad knowledge of pig suckling behaviour, which is of great importance for litter management during lactation, especially when cross-fostering is implemented. In this context, knowledge of the detailed role of sex and body weight is of particular importance because breeders rely mainly on basic body traits when managing litters.

期刊介绍:
Scientia Agricultura Sinica seeks to publish those papers that are influential and will significantly advance scientific understanding in agriculture fields worldwide. Scientia Agricultura Sinica publishes manuscripts in the categories focusing on the core subjects listed below. -Review describes new development and highlight future directions of a specialized or interdisciplinary significance in agricultural sciences. They should be focused on providing insights and summary/context on the published findings and introducing new concepts or viewpoints for solving the important unresolved questions by presenting the research background, approach, and outlook of the field. Most Reviews are solicited by the editors, but unsolicited submissions may also be considered. -Research Article presents important new research results through reproducible experimental design, using genetic, biochemical, cell and molecular biological methods, statistical analyses, and other scientific methods. -Research Notes is for a concise, but independent report representing a significant contribution to agricultural sciences. It is intended to publish these results that are exceptional interest and particularly topical and relevant, but the preliminary results. Core Subjects: -Crop Genetics & Breeding·GermplasmResources·Molecular Genetics -Tillage & Cultivation·Physiology & Biochemistry -Plant Protection -Soil & Fertilizer·Water-Saving Irrigation·Agro-Ecology & Environment -Horticulture -Storage·Fresh-Keeping·Processing -Animal Science·Veterinary Science -Agricultural Ecology -Research Notes
