“…Although quality pasture contains considerable amounts of metabolizable protein and AA [139,140] which could reach double the recommended levels for early lactation in some countries [141], its low content of rapidly fermentable carbohydrates (i.e., non-fiber carbohydrates such as starch and pectin) limits the supply of dietary energy and consequently constrains high milk and protein yields in pasture-only based diets [141,142,143]. This could contribute to the higher protein yield and/or content from milk derived through TMR compared to that of pasture based systems in some studies [69,144,145,146,147]. Rapidly fermentable carbohydrates increase the production of glucose, propionate and microbial protein which provides substrate for the cow to produce more milk and milk protein [121] due to the higher energy supply per unit [148].…”

“…The variation in the supplied energy through pasture and TMR feeding systems has been highlighted in earlier sections of this review. The increased energy supplied through TMR compared to a pasture feeding system was shown to alter milk lactose content (positive correlation) especially in high starch diets when corn and fava beans are included [144,178]. Milk derived from cows fed TMR diets had significantly higher lactose concentrations compared to that derived from cows fed pasture [12,18,147].…”

Milk is a highly nutritious food that contains an array of macro and micro components, scientifically proven to be beneficial to human health. While the composition of milk is influenced by a variety of factors, such as genetics, health, lactation stage etc., the animal’s diet remains a key mechanism by which its nutrition and processing characteristics can be altered. Pasture feeding has been demonstrated to have a positive impact on the nutrient profile of milk, increasing the content of some beneficial nutrients such as Omega-3 polyunsaturated fatty acids, vaccenic acid, and conjugated linoleic acid (CLA), while reducing the levels of Omega-6 fatty acids and palmitic acid. These resultant alterations to the nutritional profile of “Grass-Fed” milk resonate with consumers that desire healthy, “natural”, and sustainable dairy products. This review provides a comprehensive comparison of the impact that pasture and non-pasture feeding systems have on bovine milk composition from a nutritional and functional (processability) perspective, highlighting factors that will be of interest to dairy farmers, processors, and consumers.

“…In addition, an increase in the losses of unsaturated fatty acids (UFA) and total fatty acids (FA) is produced during the wilting and silage processes [ 48 ]. Furthermore, the biohydrogenation of 18:2 n-6 could be affected by the high PUFA content in the rumen [ 51 ] and, as a consequence, could increase with higher contents of these fatty acids [ 14 ]. These results show that the fatty acid profile varies depending on the production system, with a greater proportion of UFA in cows fed on pasture [ 5 ].…”

“…The nutritional quality of milk fat is largely based on its fatty acid profile, which plays a key role in many vital functions and has a direct impact on the health of consumers [ 10 ]. In general, the fatty acid content of milk changes in quantity and quality depending on factors related mainly to diet and, to a lesser extent, to the animal and the environment [ 11 , 12 , 13 ], so that fat content and the fatty acid profile can be indicators of the diet of animals [ 14 ] and the management system [ 6 ].…”

The optimization of milk production includes a rational use of forages, respect for the environment and offers the best quality to consumers. Milk production based on grass and forages produces healthier milk and it is widely spread throughout the Atlantic arc to maximize milk yield per hectare. However, the mode of offering the grass can have a major influence on milk composition. The aim of this study was to evaluate the effect of grass supply mode (grazing, zero-grazing or ensiling) on dairy cows’ performance, with particular reference to fatty acids and fat-soluble antioxidants concentration. A three by three Latin square experiment was performed with 18 dairy cows. Experimental treatments consisted of exclusive feeding with grass silage and zero-grazing, both offered ad libitum indoors, or grazing for 24 h. The results showed that grazing cows had a higher dry matter intake and greater milk yield than cows feeding on grass silage and zero-grazing, as well as higher concentrations of protein, lactose, nonfat-solids and urea in milk than housed cows. Milk fat from grazing cows had a higher proportion of unsaturated fatty acids than from cows feeding on grass silage and zero-grazing, with significant differences in the proportion of vaccenic and rumenic acids. The 18:1 trans-11 to 18:1 trans-10 ratio is proposed as biomarker to identify the milk produced from the management system of grazing cattle. Milk from grazing cows had a greater proportion of lutein than cows eating grass silage, with the zero-grazing system having intermediate values. In conclusion, the mode of grass supply affects fatty acid and antioxidant profiles of milk.

“…Thus, several studies for the authentication of feeding systems on dairy products have been conducted in recent decades and recently reviewed by Prache et al (2020). Among others, Vicente et al (2017), Hurtaud et al (2014), and Mitani et al (2016) successfully used milk fatty acids (FA) to authenticate cow feeding systems. Vitamins and carotenoids in milk were used to authenticate pasture feeding of cows (Segato et al, 2017), and volatile organic compounds were tested for authentication purposes (Valdivielso et al, 2017;Bergamaschi et al, 2020).…”

The ability of mid-infrared spectroscopy (MIR) to predict indicators (1) of diet composition in dairy herds and (2) for the authentication of the cow feeding restrictions included in the specification of 2 Protected Designation of Origin (PDO) cheeses (Cantal and Laguiole) was tested on 7,607 bulk milk spectra from 1,355 farms located in the Massif Central area of France. For each milk sample, the corresponding cow diet composition data were obtained through on-farm surveys. The cow diet compositions varied largely (i.e., from full grazing for extensive farming systems to corn silage-based diets, which are typical of more intensive farming systems). Partial least square regression and discriminant analysis were used to predict the proportion of different feedstuffs in the cows' diets and to authenticate the cow feeding restrictions for the PDO cheese specifications, respectively. The groups for the discriminant analysis were created by dividing the data set according to the threshold of a specific feedstuff. They were issued based on the specifications of the restriction of the PDO cheese. The pasture proportion in the cows' diets was predicted by MIR with an coefficient of determination in external validation (R 2 V) = 0.81 and a standard error of prediction of 11.7% dry matter. Pasture + hay, corn silage, conserved herbage, fermented forage, and total herbage proportion in the cows' diets were predicted with a R 2 V >0.61 and a standard error of prediction <14.8. The discrimination models for pasture presence, pasture ≥50%, and pasture ≥57% in the cows' diets achieved an accuracy and specificity ≥90%. A sensitivity and precision ≥85% were also observed for the pasture proportion discrimination models, but both of these indexes decreased at increasing thresholds from 0 to 50, and 57% pasture in the cows' diets. An accuracy ≥80% was also observed for pasture + hay ≥72%, herbage ≥50%, pasture + hay ≥25%, absence of fermented herbage, absence of corn silage, and corn silage ≤30% in the cows' diets, but for several models, either the sensitivity or precision was lower than the accuracy. Models built on the simultaneous respect of all the criteria of the feeding restrictions of PDO cheese specifications achieved an accuracy, specificity, sensitivity, and precision >90%. Both the regression and discriminant MIR models for bulk milk can provide useful indicators of cow diet composition and PDO cheese specifications to producers and consumers (farmers, dairy plants).
