Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

open access: yesAnimal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Identification and validation of a regulatory mutation upstream of the BMP2 gene associated with carcass length in pigs

open access: yesGenetics Selection Evolution, 2021
Background Carcass length is very important for body size and meat production for swine, thus understanding the genetic mechanisms that underly this trait is of great significance in genetic improvement programs for pigs. Although many quantitative trait

Influence of Image Analysis and Carcass Traits on Beef Carcass Price

open access: yesNihon Chikusan Gakkaiho, 2003
北海道内の枝肉市場に上場された黒毛和種去勢牛(1,543頭)および交雑種去勢牛(532頭)の枝肉横断面の画像に対し,脂肪面積比,全体の粒子のあらさ,最大粒子のあらさ,ロース芯の短径・長径比およびロース芯形状の複雑さを画像解析形質として分析に用いた.格付形質としては,枝肉重量,ロース芯面積,バラの厚さ,皮下脂肪厚,BMSナンバー,BCS等級およびBFS等級を用いた.これらの形質が牛枝肉価格にどのような影響があるかを検討した.取り上げた14種類のモデルのうち,格付形質のみおよび画像解析形質を含む2種類の,計3モデルについて詳細に検討した.3種類のモデルの決定係数は,黒毛和種で0.799~0.825,交雑種で0.784~0.792の範囲にあった.価格に最も影響を与えた形質は ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Whole genome scan in chickens for quantitative trait loci affecting carcass traits

open access: yesPoultry Science, 1999
An experiment was conducted to enable quantitative trait loci (QTL) mapping for carcass traits. The population consisted of 10 full-sib families originating from a cross between male and female founders chosen from two different outcross broiler lines. Founder animals, parents, offspring, and grandoffspring are denoted as generation (G) 0, 1, 2, and 3 ...

Genomic Structural Variations Provide Insights Into Litter Size and Teat Number Traits in Hu Sheep

open access: yesAnimal Research and One Health, EarlyView.
Here, we conducted whole genome sequencing on 300 Hu sheep with an average depth of 16.51X. Two candidate genes associated with litter size and teat number traits were identified, namely MAST2 and AFDN. ABSTRACT Litter size and the teat number are important economic indicators in sheep production.

Chromium propionate improves performance and carcass traits in broilers

open access: yesAnimal Nutrition, 2020
There is evidence to suggest that poultry may have a dietary requirement for metabolically available chromium (Cr) that exceeds the amount provided through wheat soybean meal diets.

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

open access: yesAnimal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Why we age

open access: yesBiological Reviews, EarlyView.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Genomic Regions Associated With Skeletal Type Traits in Beef and Dairy Cattle Are Common to Regions Associated With Carcass Traits, Feed Intake and Calving Difficulty

open access: yesFrontiers in Genetics, 2020
Linear type traits describing the skeletal characteristics of an animal are moderately to strongly genetically correlated with a range of other performance traits in cattle including feed intake, reproduction traits and carcass merit; thus, type traits ...
