“…Production of trans FA isomers in the rumen causes depression of milk fat, and ruminal biohydrogenation of FA provides a clue to the source of specific trans FA isomers used by the mammary enzymes for secretion in milk (Tripathi, 2015). The ability of ruminal microbial biohydrogenation, which transforms the UFA of dietary fat to saturated FA, to change milk FA composition irrespective of the dietary FA composition is limited.…”

Feed is the main factor impacting the composition and quality of milk of dairy animals. Therefore, the present review explores the effects of feed and nutrition on milk fat content and levels of healthy fatty acids (FA) in milk consumed by humans. Milk and dairy products are two main sources of healthy and unhealthy FA in human nutrition. The concentrations of FA in milk depend mainly on diets; therefore, milk FA concentrations and ratios can be greatly altered by some feeding strategies. Dietary supplementation of the diets of dairy livestock with vegetable seeds or oils, microalgae and phytogenic feed additives, and feeding of some grasses can enhance the contents of healthy FA, including n-3 FA, α-linolenic acid, conjugated linoleic acid (CLA) and, generally, unsaturated FA in milk and dairy products. Enrichment of milk with healthy FA may make milk a source of anticarcenogens (CLA and polyphenols) for human health. This review, therefore, focusses on the current research findings on enrichment of milk with healthy FA and summarizes some effective supplementation strategies to alter milk FA profile.

“…Biohydrogenation of linolenic and linoleic acids produced a trans -10 double bond intermediate. Ruminal bacteria can produce a trans -10, cis -12 CLA, while mixed rumen microorganisms can convert oleic acid to trans FA and also produce a trans -10 isomer (Tripathi, 2015).…”

“…Altering the milk protein profile and bioactive properties of the milk by manipulating the diet of the dairy cow offers a promising approach to naturally enhance the healthfulness of milk products. Research examining the relationship between nutrition and the bovine milk protein profile is limited and nutrition is a significant management factor that has the potential to alter milk protein composition (Kennelly et al, 2005; Tripathi, 2014). Christian et al (1999) altered the proportions of high abundance bovine milk proteins by feeding a lupin-wheat-based diet, a high RUP source, to lactating dairy cows compared with cows fed spring-pasture, a high RDP source.…”

Little is known about the bovine milk proteome or whether it can be affected by diet. The objective of this study was to determine if the dietary rumen degradable protein (RDP):rumen undegradable protein (RUP) ratio could alter the bovine milk proteome. Six Holstein cows (parity: 2.5 ± 0.8) in mid lactation were blocked by days in milk (80 ± 43 d in milk) and milk yield (57.5 ± 6.0 kg) and randomly assigned to treatment groups. The experiment was conducted as a double-crossover design consisting of three 21-d periods. Within each period, treatment groups received diets with either (1) a high RDP:RUP ratio (RDP treatment: 62.4:37.6% of crude protein) or (2) a low RDP:RUP ratio (RUP treatment: 51.3:48.7% of crude protein). Both diets were isonitrogenous and isoenergetic (crude protein: 18.5%, net energy for lactation: 1.8 Mcal/kg of dry matter). To confirm N and energy status of cows, dry matter intake was determined daily, rumen fluid samples were collected for volatile fatty acid analysis, blood samples were collected for plasma glucose, β-hydroxybutyrate, urea nitrogen, and fatty acid analysis, and total 24-h urine and fecal samples were collected for N analysis. Milk samples were collected to determine the general milk composition and the protein profile. Milk samples collected for high-abundance protein analysis were subjected to HPLC analysis to determine the content of α-casein, β-casein, and κ-casein, as well as α-lactalbumin and β-lactoglobulin. Samples collected for low-abundance protein analysis were fractionated, enriched using ProteoMiner treatment, and separated using sodium dodecyl sulfate-PAGE. After excision and digestion, the peptides were analyzed using liquid chromatography (LC) tandem mass spectrometry (MS/MS). The LC-MS/MS data were analyzed using PROC GLIMMIX of SAS (version 9.4, SAS Institute Inc., Cary, NC) and adjusted using the MULTTEST procedure. All other parameters were analyzed using PROC MIXED of SAS. No treatment differences were observed in dry matter intake, milk yield, general milk composition, plasma parameters, or rumen volatile fatty acid concentrations, indicating no shift in total energy or protein available. Milk urea N and plasma urea N concentrations were higher in the RDP group, indicating some shift in N partitioning due to diet. A total of 595 milk proteins were identified, with 83% of these proteins known to be involved in cellular processes. Although none of the low-abundance proteins identified by LC-MS/MS were affected by diet, feeding a diet high in RUP decreased β-casein, κ-casein, and total milk casein concentration. Further investigations of the interactions between diet and the milk protein profile are needed to manipulate the milk proteome using diet.

Resumo -O objetivo deste trabalho foi avaliar o efeito da interação entre sistemas produtivos e estações do ano sobre a qualidade química e microbiológica do leite bovino, além de propor um índice de potencial nutracêutico do perfil de ácidos graxos do leite. Três propriedades foram avaliadas mensalmente, durante as diferentes estações do ano, em quatro graus de especialização dos sistemas de produção: altamente especializado, especializado, semiespecializado e não especializado. Os sistemas de produção e as estações do ano interferem de forma conjunta no perfil de ácidos graxos e, de forma isolada, na qualidade química e microbiológica do leite. As maiores contagens de células somáticas e os menores conteúdos de proteína foram observados no verão, e o grau de especialização das unidades produtivas esteve indiretamente relacionado à contagem bacteriana total no leite. No inverno, sistemas não especializados produziram leite com o melhor índice nutracêutico, que apresentaram os maiores teores de ácidos graxos poli-insaturados, ácido rumênico (CLA, 18:2n7-c9,t11) e ácido t10,c12-octadecadienoico (CLA, 18:2n6-t10,c12).Termos para indexação: ácido linoleico conjugado, alimentos funcionais, perfil de ácidos graxos, qualidade do leite bovino. Quality and nutraceutical potential of bovine milk in different production systems and seasonsAbstract -The objective of this work was to evaluate the effect of the interaction between production systems and seasons on the chemical and microbiological qualities of bovine milk, besides proposing a potential nutraceutical index of milk fatty acid profiles. Three farms were assessed monthly, along the different seasons, for four specialization levels of the production systems: highly specialized, specialized, partially specialized, and nonspecialized. The production systems and the seasons jointly interfere in fatty acid profiles, and singly interfere in the chemical and microbiological quality of milk. The highest somatic cell counts and the lowest protein contents were observed in the summer, and the specialization level of the production units had an inverse relationship with the total bacterial count. During winter, nonspecialized systems produced milk with the best nutraceutical index, with the highest contents of polyunsaturated fatty acids, rumenic acid (CLA, 18:2n7-c9,t11) and t10,c12-octadecadienoic acid (CLA,c12).
