the liquor collectd with rumenocentesis is very representative of the rumen liquor. Some reserches have demonstrated this. When the liquor is collected with oroesofageal tubes marked differences can be observed on pH and total AGV for the saliva contamination, but samples are representative for the AGV profile and microbiota profile tests.

The transition period, 3 weeks before to 3 weeks after parturition, is important for health, reproduction, production and profitability of dairy cows (Bertoni et al., 2008). In this period cows are affected by different stressors including the increase of body lipid mobilization, oxidative stress, major changes in endocrine status, and altered immune function, which together result i ...

Fertility is the result of so many factors that the definition of Fromageot (1978) is not surprising: reproduction can be considered a “luxury” function. In fact, several experiments have demonstrated how numerous and different are the causes of reduced fertility. Among them, nutrition has a relevant role (Wolter, 1973; Bertoni, 1990; Ferguson, 1991) related to th ...

In non-ruminants, the peroxisome proliferator-activated receptors (PPAR) play a crucial role in the regulation of fatty acid metabolism and inflammatory responses . The PPAR family is composed of three subtypes: PPAR-gamma (PPARG), PPAR-alpha (PPARA), and PPARδ/β (PPARD), among which the expression of PPARG and PPARA subtypes are associated with adipogenesis/lipogenesi ...

The peripartal or “transition” period in taurine cattle is considered the most important phase of the lactation cycle because during this time animals are most-susceptible to metabolic or infectious disorders (Drackley 1999; Van Knegsel et al. 2014). The immune and innate host resistance mechanisms (Mallard et al. 1998) are impaired during the peripartal period, often re ...

The liver performs essential functions in mammals. These include, but are not limited to, gluconeogenesis and glycogen synthesis, synthesis of several plasma proteins encompassing clotting factors and acute phase proteins (APP) (e.g., haptoglobin, albumin, and fibrinogen), metabolism of amino acids and lipids, and detoxification including ammonia removal [1,2]. During the period aro ...
