Estimation of Sow Backfat Thickness Based on Machine Vision [PDF]

Animals
Controlling the backfat thickness of sows within an appropriate range during different production stages helps to increase the number of pigs weaned per sow per year and ultimately enhances the economic benefit to the pig farm.

Genetic architecture of backfat thickness in laying hens: implications for extended egg production [PDF]

Genetics Selection Evolution
Background To extend the egg production period of laying hens, it is important to understand the energy trade-offs during the late laying period (after 80 weeks of age) to avoid decreasing egg production or compromising health through inadequate body ...

Changes in quality and aroma compounds of Hu sheep with different backfat thicknesses

Applied Food Research
Backfat thickness demonstrates significant correlations with reproductive efficiency, growth performance, and meat quality parameters in lambs. In this study, we selected six Hu sheep with high backfat thickness and six with low backfat thickness.

Sex-specific microbiota associations with backfat thickness, eye muscle area, and rumen fermentation in Qinchuan cattle [PDF]

BMC Microbiology
Background Ruminant livestock are essential for global food production, and understanding sex-specific rumen fermentation and microbial differences is key to improving production efficiency and meat quality. This study explored sex-specific variations in

Genetic architecture and major genes for backfat thickness in pig lines of diverse genetic backgrounds [PDF]

Genetics Selection Evolution, 2021
Background Backfat thickness is an important carcass composition trait for pork production and is commonly included in swine breeding programmes. In this paper, we report the results of a large genome-wide association study for backfat thickness using ...

Shunt fostering on a large-scale commercial pig farm in Hungary: Interplay between backfat thickness and piglet weaning performance [PDF]

BIO Web of Conferences
Shunt fostering, also known as fall-behind management, is a unique piglet management strategy in commercial pig farming. We investigated the effects of shunt fostering on sow backfat thickness and piglet weaning.

Population genetic structure analysis and identification of backfat thickness loci of Chinese synthetic Yunan pigs [PDF]

Frontiers in Genetics, 2022
Yunan is a crossed lean meat pig breed in China. Backfat thickness is the gold standard for carcass quality grading. However, over 14 years after breed registration, the backfat of Yunan thickened and the consistency of backfat thickness decreased ...

Backfat Thickness at Pre-Farrowing: Indicators of Sow Reproductive Performance, Milk Yield, and Piglet Birth Weight in Smart Farm-Based Systems [PDF]

Agriculture, 2023
The importance of backfat thickness in sows lies in its correlation with nutritional status, reproductive performance, and overall health. Identifying the optimum backfat thickness is crucial for determining the ideal energy reserves needed to support ...
