Flavonoid supplementation may modify the behavior and rumen inflammatory response of fattening bulls, and this could be related to the concentrate presentation (mash or pellet) form. In the present study, 150 Holstein bulls (183.0 ± 7.53 kg BW and 137 ± 1.8 d of age) were randomly allocated to one of eight pens and assigned to control (C) or (BF) (Citrus aurantium, Bioflavex CA, HealthTech Bio Actives, Spain, 0.4 kg per ton of concentrate of Bioflavex CA, 20% naringin). Concentrate (pellet) intake was recorded daily, and BW and animal behavior fortnightly. Animals were slaughtered after 168 d of study, and ruminal epithelium samples were collected for gene expression analyses. Treatment did not affect animal performance; however, BF supplementation reduced agonistic interactions and oral non-nutritive behaviors and increased the time devoted to eating concentrate and ruminating activity (p < 0.05). The gene expression of some genes in the rumen epithelium was greater or tended to be greater in BF than C bulls (bitter taste receptor 16, cytokine IL-25, β-defensin; p < 0.10; pancreatic polypeptide receptor 1 and tumor necrosis factor alpha; p < 0.05). In conclusion, flavonoid supplementation modifies the expression of genes in the rumen epithelium that could be related to inflammation and animal behavior modulation.

Генотипирование 51 быка голштинской породы немецкой и голландской селекции по гену каппа-казеина показало, что наибольшая частота встречаемости желательного аллеля CSN3В зафиксирована у быков-производителей голландской селекции (21,43%), что на 4,4% выше встречаемости его у немецких быков. Наиболее желательный генотип CSN3ВВ каппа-казеина в изучаемом поголовье не выявлен. Частота встречаемости генотипа CSN3АВ гена каппа-казеина у быков из Нидерландов составила 42,86%, или на 8,8% выше, чем у немецких быков. Изучено влияние быков голштинской породы разного происхождения, различающихся по генотипам гена каппа-казеина на динамику живой массы их дочерей от рождения до возраста 3-й лактации. Установлено, что от быков с генотипом CSN3АВ как немецкой, так и голландской селекции рождались телочки с большей живой массой; при этом дочери быков с генотипом CSN3АА лучше росли в период от 6 до 18 мес независимо от происхождения. Живая масса дочерей быков немецкой селекции при первом оплодотворении была одинаковой, в голландской селекции преимущество на 20,4 кг имели дочери быков с генотипом CSN3АВ гена каппа-казеина. Максимальную живую массу к возрасту 1-й лактации имели дочери быков немецкой селекции с генотипом CSN3АВ (521 кг), дочери быков голландской селекции с генотипом CSN3АА (520,5 кг). У коров 3-й лактации наивысшая живая масса была у обладателей генотипа CSN3АВ (568,5 кг и 581,3 кг), в группах немецкой и голландской селекции, соответственно.Genotyping of 51 Holstein bulls of German and Dutch breeding on the Kappa-casein gene showed that the highest frequency of occurrence of the desirable allele CSN3B was recorded in Dutch breeding bulls (21.43%), which is 4.4% higher than its occurrence in German bulls. Most desirable CSN3ВВ genotype of Kappa-casein in the studied population were not identified. Frequency of genotype CSN3АВ of the gene Kappa-casein bulls from the Netherlands amounted to 42,86%, or 8.8% higher than the German bulls. Influence of the bulls of golshtinsky breed of different origin differing on gene genotypes of a Kappa-casein on dynamics of live mass of their female calves from the birth to the age of the 3rd lactation is studied. It is established that heifers with higher live weight were born from the bulls with genotype CSN3АВ both the German and Dutch breeding; moreover, the female calves of bulls with genotype CSN3АА grow better in the period from 6 to 18 months regardless of origin. The live weight of female calves of bulls of the German selection at the first insemination was the same, in the Dutch selection female calves of bulls with genotype CSN3АВ of the gene Kappa-casein had advantage of 20.4 kg. The maximum live weight by the age of the 1st lactation had female calves of bulls of German selection with genotype CSN3AV — 521 kg, female calves of bulls of Dutch selection-with genotype CSN3AA (520.5) kg. — with a genotype of CSN3AA (520.5) kg had the maximum live weight. The 3rd lactation cows had the highest live weight with CSN3AB genotype — 568.5 kg and 581.3 kg, in groups of the German and Dutch selection, respectively.

AbstractMetabolic consequences of an energy and protein rich diet can compromise metabolic health of cattle by promoting a pro-inflammatory phenotype. Laminitis is a common clinical sign, but affected metabolic pathways, underlying pathophysiology and causative relationships of a systemic pro-inflammatory phenotype are unclear. Therefore, the aim of this study was to elucidate changes in metabolome profiles of 20 months old Holstein bulls fed a high energy and protein diet and to identify novel metabolites and affected pathways, associated with diet-related laminitis. In a randomized controlled feeding trial using bulls fed a high energy and protein diet (HEP; metabolizable energy [ME] intake 169.0 ± 1.4 MJ/day; crude protein [CP] intake 2.3 ± 0.02 kg/day; calculated means ± SEM; n = 15) versus a low energy and protein diet (LEP; ME intake 92.9 ± 1.3 MJ/day; CP intake 1.0 ± 0.01 kg/day; n = 15), wide ranging effects of HEP diet on metabolism were demonstrated with a targeted metabolomics approach using the AbsoluteIDQ p180 kit (Biocrates Life Sciences). Multivariate statistics revealed that lower concentrations of phosphatidylcholines and sphingomyelins and higher concentrations of lyso-phosphatidylcholines, branched chain amino acids and aromatic amino acids were associated with an inflammatory state of diet-related laminitis in Holstein bulls fed a HEP diet. The latter two metabolites share similarities with changes in metabolism of obese humans, indicating a conserved pathophysiological role. The observed alterations in the metabolome provide further explanation on the underlying metabolic consequences of excessive dietary nutrient intake.
