The effect of backfat thickness at mating on the reproductive and productive performances of ewes
Small Ruminant Research, 2012Three Egyptian sheep breeds (Rahmani, n = 40; Barki, n = 50; Ossimi, n = 36) were used to investigate the effect of backfat thickness of ewes, at mating, on their subsequent reproductive and productive performances. Ewes were assigned to four groups, according to their backfat thickness (

Fatty acid composition of backfat in large white pigs selected for low backfat thickness
Meat Science, 1978Samples of midback fat were taken from 157 Large White boars and analysed for fatty acid composition and melting point of lipid. Seventy-seven boars were from a line showing fast efficient growth and low backfat depth (selection line) and 80 from a random-mated control line. All were performance-tested from 27 to 87 kg liveweight on ad libitum feeding.

Backfat thickness of young boars for meat production
BSAP Occasional Publication, 1984Concern is being expressed about the marketing of over-lean carcasses, especially from young boars. Experiments at Terrington have tested the effects of various management practices, feeding regimes and slaughter weights on the performance and backfat thickness of young boars reared for meat production.Pigs were kept in groups of mixed castrates and ...

Fat mobilisation in large white pigs selected for low backfat thickness
Journal of the Science of Food and Agriculture, 1980AbstractPlasma free fatty acid (FFA), glucose and insulin responses to feeding and fasting were investigated in a sample of two lines of Large White pigs. One line had been selected for nine generations against backfat thickness and for improved growth rate and feed conversion efficiency. The other line had been randomly bred for six generations.

Reproductive performance of gilts according to growth rate and backfat thickness at mating
Animal Reproduction Science, 2010The study evaluated the influence of growth rate (GR) and backfat thickness (BF), at first mating of gilts, on the reproductive performance until the first farrowing and on the variation in birth weight of piglets. Gilts were categorized into three groups according to GR from birth until the first mating: GRI (600-700 g/d; n = 345), GRII (701-770 g/d ...

The causes of seasonal variation in backfat thickness of pigs in Western Australia
Australian Journal of Agricultural Research, 2004Anecdotal observations suggest that pigs get fatter at certain times of the year. Abattoir data from a major Western Australian genotype were investigated to determine whether there is seasonal variation in P2, and if so, what factors may contribute to this.

A comparison of ultrasonic machines for the prediction of backfat thickness in the live pig
Australian Journal of Experimental Agriculture and Animal Husbandry, 1984Measurements of the backfat thickness over the last rib, 65 mm from the dorsal midline, were taken on 122 live pigs with five different ultasonic machines: Sonatest, Medata, Renco, Sonalyser and Ilis. These measurements were examined for their ability to predict the corresponding carcass introscope measurements.

Backfat thickness in pigs is positively associated with leptin mRNA levels
Canadian Journal of Animal Science, 1998The obese (ob) gene isolated from ob/ob mice in 1994 is expressed specifically in adipose tissue. The gene product, leptin, regulates food intake, energy expenditure and puberty. Reported herein is a 2477 bp mRNA sequence for the pig obese gene, which includes the complete coding sequence.
