| The aim was to quantify the factors influencing the detailed milk fatty acid profile. The results of large scale screening of the Danish dairy cattle population for a detailed milk fat composition revealed profound effects of breed, production system, parity, lactation stage and genetics. This opens up the possibility to differentiate the milk at farm level, by management and breeding strategies. |

| Projektet SOBcows har i samarbejde med RYK gennem 16 måneder i 2015/16 analyseret for indholdet af 11 fedtsyrer/fedtsyregrupper i kontrolmælken fra alle ydelseskontrollerede køer i Danmark. Dataanalyser af godt 3,5 mio. mælkeprøver viser, at det er muligt at påvirke sammensætning af mælkefedtet gennem avl. En foreløbig beregning af arvbarheden hen over laktationen viser, at alle fedtsyrekategorier har en genetisk variation og enkeltfedtsyrerne har arvbarheder på højde med den samlede fedtydelse. Det betyder arvbarheder i intervallet 0,25-0,44 afhængig af race og paritet. De genetiske sammenhænge varierer betydeligt gennem laktationen og er påvirket af den øgede kropsmobilisering i de første måneder efter kælvning. En anvendelse af fedtstyrebestemmelserne i... |

| This presentation provides an overview of the results from the projects "The optimal cow" and "SOBcows". The aim of "The optimal cow" is to derive economic values for breeding goal traits in four different production systems, among them an organic production system. The aim of "SOBcows" is to enhance the size and the profitability of the organic dairy production by adapting the breeding material to organic production circumstances and by indicating sustainable methods for sustainable niche production based on animals with specific genetic characteristics |

| In this paper we present the results of a genome-wide association study to identify significant genes that contribute to genetic variation in abundant milk fatty acids (FAs) C14:0 and C16:0 with considering lactation stage effect. FA composition phenotypes were measured using Application Note 64 (FOSS) and were available on 24,661 milk samples from 3,213 Danish Holstein cows. Association mapping analyses was performed using a Bayesian Variable Selection method. Results showed, in total 21 significant SNPs were detected for C14:0 and 18 significant SNPs were detected for C16:0 that are significant in changing over lactation stage for abundant milk FAs C14:0 and C16:0. For both milk FAs most significant SNPs influencing the slope of the lactation curve were... |

| Projektet SOBcows har i samarbejde med RYK gennem 16 måneder i 2015/16 analyseret for indholdet af fedtsyrer i kontrolmælken fra alle ydelseskontrollerede køer i Danmark. Rapporten præsenterer opgørelser på målingerne og evaluerer potentialet i at bruge viden om mælkens fedtsyreprofil i avl og produktion samt i forhold til fedtsyrernes betydning for human sundhed. En litteraturgennemgang viser, at fedtsyresammensætningen i komælk varierer betydeligt og er påvirket af en række faktorer relateret til fodring, race og management. Fodring med græs- eller urtebaserede rationer øger mælkens indhold af umættede C18-fedtsyrer, og tilsvarende øger fodring med mættet fedt indholdet af palmitin– og stearinsyre (C16:0 og C18:0) i mælkefedtet. Litteraturen viser... |

| Abstract Milk fatty acid (FA) composition can be manipulated through feeding, and especially effects of grazing have been shown to promote a healthier milk FA profile due to increasing contents of beneficial FAs, like conjugated linoleic acid (CLA) and α-linolenic acid (C18:3, the main n3 FA in milk). In addition to diet-based manipulations, selective breeding for specific FA could also be a strategy for altering the FA profile as milk FA display low to moderate heritabilites (0.07-0.34 in Danish Holstein). Since 2015, milk samples from all Danish dairy cows under yield control have been analyzed using mid infrared spectroscopy. The FOSS Application Note 64 has subsequently been used to predict content of seven FA groups (short-chain FA (SCFA),... |

| The fatty acid (FA) composition of bovine milk may be related to human health and technological properties of dairy products. The FA composition can be altered both through management and breeding. Large scale FA profiling of the Danish dairy cattle population has now been implemented for more than a year. For the first time access to millions of FA observations across an entire dairy population enables in depth analysis of the factors affecting the FA profile of milk. This was the aim of this study. For 12 months more than 3.5 million milk samples from four Danish dairy breeds had been analyzed using mid infrared spectroscopy and application of FOSS Application Note 64 for predicting content of seven FA groups and four individual FA. The results showed... |
