“…The effect of forage conservation (fresh vs . ensiled) is more pronounced on milk VA concentrations than forage species, as reported in previous multivariate analyses . In the present study, milk fat VA concentrations were not affected by dietary treatment despite the slightly higher ALNA intakes observed with higher WC intake.…”

“…This may indicate that a smaller proportion of dietary ALNA was hydrogenated to VA in the rumen when cows were fed the WC‐containing diets. Although fresh grass consumption (either grazed or zero‐grazed) may result in an increase in milk VA concentrations, the effect of grazing was more pronounced when compared with zero‐grazing practices (such as those used in the current work) in other studies…”

“…Approximately half of milk C16:0 originates from endogenous synthesis by the mammary gland, and therefore its concentrations can be influenced by the diet, either directly or by influencing the ruminal production of substrates for the subsequent de novo synthesis in the mammary gland . Increased fresh forage intake in the total diet may reduce milk concentrations of C16:0 and total SFA, but the effect of forage species is not as pronounced . Therefore, the similar dietary forage:concentrate ratio across dietary treatments in the present study may explain the lack of effects on total and individual SFA concentrations in milk.…”

Effect of substituting fresh‐cut perennial ryegrass with fresh‐cut white clover on bovine milk fatty acid profile

et al. 2018

BACKGROUNDIncluding forage legumes in dairy systems can help address increasing environmental/economic concerns about perennial ryegrass monoculture pastures. This work investigated the effect of substituting fresh‐cut grass with increasing quantities of fresh‐cut white clover (WC) on milk fatty acid (FA) profile and transfer efficiency of dietary linoleic (LA) and α‐linolenic (ALNA) acids to milk fat. Three groups of three crossbred dairy cows were used in a 3 × 3 crossover design. Dietary treatments were 0 g kg−1 WC + 600 g kg−1 grass, 200 g kg−1 WC + 400 g kg−1 grass, and 400 g kg−1 WC + 200 g kg−1 grass. All treatments were supplemented with 400 g kg−1 concentrates on a dry matter basis. Cows had a 19‐day adaptation period to the experimental diet before a 6‐day measurement period in individual tie stalls.RESULTSIncreasing dietary WC did not affect dry matter intake, milk yield or milk concentrations of fat, protein or lactose. Milk polyunsaturated FA concentrations (total n‐3, total n‐6, LA and ALNA) and transfer efficiency of LA and ALNA were increased with increasing dietary WC supply.CONCLUSIONInclusion of WC in pastures may increase concentrations of nutritionally beneficial FA, without influencing milk yield and basic composition, but any implications on human health cannot be drawn. © 2018 The Authors.

“…Moreover, from an animal welfare perspective, the negative effects of the driving down transhumance might be amplified by the recent evolution of the dairy sector in the mountains. In many alpine regions, autochthonous cattle breeds, well adapted to the alpine environment, have been indeed massively replaced by specialised dairy breeds that have more difficulty to cope with pasture grazing (Battaglini et al 2014;Knaus 2015;Stergiadis et al 2015). According to D'Hour et al (1994), the extreme walking exercise of the transhumance could be particularly detrimental for high producing dairy cattle when managed under extensive systems.…”

The study aimed at verifying if the prolonged walking and fasting of the driving down transhumance from an alpine pasture to the farm of origin at the end of the summer grazing may impair health and productive response of lactating cows belonging to two specialised dairy breeds. The study considered a herd of 380 dairy cows and heifers of Italian Holstein and Italian Brown breeds that faced a driving down transhumance with a vertical drop of about 1050 m. The animals walked for about 40 km completing the journey in 23 h, including three resting periods. Ten Holstein and nine Brown lactating cows were selected and monitored before and after the driving down transhumance taking individual blood samples and recording milk yield. The prolonged physical exercise and the limited water and energy intake during the driving down transhumance impaired cows' metabolic profile resembling a status of ketosis. A significant drop in milk yield was observed in all the monitored animals regardless of the breed. The production loss was more severe (49.4%) in cows with high milk yield and less days in milk. These animals required also a prolonged time to recover from the milk drop due to the driving down transhumance and, based on these findings, they should be excluded from this practise.

Recently, the Swiss breeding association reported an increasing number of white-spotted cattle in the Brown Swiss breed, which is normally solid brown coloured. A total of 60 Brown Swiss cattle with variably sized white abdominal spots, facial markings and depigmented claws were collected for this study. A genome-wide association study using 40k SNP genotypes of 20 cases and 1619 controls enabled us to identify an associated genome region on chromosome 22 containing the MITF gene, encoding the melanogenesis associated transcription factor. Variants at the MITF locus have been reported before to be associated with white or white-spotted phenotypes in other species such as horses, dogs and mice. Whole-genome sequencing of a single white-spotted cow and subsequent genotyping of 172 Brown Swiss cattle revealed two significantly associated completely linked single nucleotide variants (rs722765315 and rs719139527). Both variants are located in the 5 0regulatory region of the bovine MITF gene, and comparative sequence analysis showed that the variant rs722765315, located 139 kb upstream of the transcription start site of the bovine melanocyte-specific MITF transcript, is situated in a multi-species conserved sequence element which is supposed to be regulatory important. Therefore, we hypothesize that rs722765315 represents the most likely causative variant for the white-spotting phenotype observed in Brown Swiss cattle. Presence of the mutant allele in a heterozygous or homozygous state supports a dominant mode of inheritance with incomplete penetrance and results in a variable extent of coat colour depigmentation.
