“…Deterioration in milk composition is also observed (4). Although a range of energy additives to ruminant diets has been extensively investigated (7,48), an ongoing research focused on the negative energy balance of periparturient dairy cows is required (29,50). In this regard, much attention is given, among others, to the use of energy feed additives in dairy cow diets and to their impact on animal metabolism and performance, as well as on milk composition.…”

High-producing dairy cows require an appropriate management system, good care, and a tailored nutritional program that provides well-balanced feed rations. High yielders, especially during the periparturient period, normally show a reduced feed intake with a concomitant increased demand for nutrients for milk synthesis. Thus, the incidence of metabolic disorders may greatly increase, and consequently, a decrease in milk production is noted. Deterioration in milk composition is also observed (4). Although a range of energy additives to ruminant diets has been extensively investigated (7,48), an ongoing research focused on the negative energy balance of periparturient dairy cows is required (29,50). In this regard, much attention is given, among others, to the use of energy feed additives in dairy cow diets and to their impact on animal metabolism and performance, as well as on milk composition. Each of gluconeogenic precursors, such as glycerol (51), propylene glycol (28), sodium or calcium salts of propionate (30), has a different route for conversion to glucose. Depending on their type and administration period, energy supplements may contribute to reducing metabolic disturbances during the transition period. Propylene glycol may affect glucogenic action in different ways. A portion of this substance is metabolized in the rumen to lactic acid Klebaniuk R., Kochman G., Kowalczuk-Vasilev E., Grela E. R., Bąkowski M., Olcha M., Dunster F.Energy efficiency of diet for periparturient dairy cows supplemented with free fatty acids or glucogenic additives Summary The aim of the study was to compare the efficiency of two energy preparations used at fixed doses, but for different lengths of time: 1) a loose mixture of propylene glycol and sodium propionate, and 2) a granular formulation of free fatty acids produced from palm oil and palm nut, non-degradable in the rumen.A three-factorial experiment was carried out on 5 groups of Polish Black and White Holstein-Friesian cows (10 animals each) which were within the transition period. The aim of the experiment was to determine the effect of two energy preparations administered at a constant dose, but over different time periods, on the animals' performance, as well as on their milk yield and composition. The following treatment groups were formed: control group C, which received a standard diet; experimental groups G1 and G2, which received a dietary additive of a glucogenic preparation; and experimental groups F1 and F2, which received a free fatty acid preparation. The diet of the transition cows was supplemented with the full dose of the additives (500 g/ head/day) for 2 weeks before the expected calving and 3 or 6 weeks of lactation.The present research confirmed the benefits of dietary inclusion of energy supplements for transition cows. Supplementation with both glucogenic and free fatty acid preparations reduced the negative energy balance in the cow's organism and improved milk production and composition. The milk yield, higher by ca. 10% for the cows fed diets with...

“…Aunque se sabe que los taninos de alto peso molecular pueden formar complejos con celulosa, hemicelulosa entre otros compuestos, haciéndolos no disponibles para la población bacteriana, se ha evidenciado que en algunos casos el uso de taninos condensados no afectó el desempeño ni el balance de nitrógeno en ovinos. Szczechowiak et al (2016) ensayaron una mezcla de taninos condensados y aceites de pescado y soya, en vacas para ver su efecto sobre la fermentación ruminal, la concentración de metano y la proporción de ácidos grasos en liquido ruminal y leche; encontrando que hubo un efecto inhibitorio en la producción de metano, pero sin efecto aditivo en la bio-hidrogenación, factor atribuido al efecto de los taninos y su posible interacción con los aceites utilizados.…”

Given the steady population growth at the global level observed in the passage of time, there has been perceived the need to have a social scheme where the offer of healthy food is constant and sufficient to settle the existing insufficiencies in the human population. Before this situation, the efficiency of the cattle models of animal production has turned out to be awkward as a result of the competition of the animal species for the nutritive resources that the man consumes. For such a motive, the need to recognize and to characterize new food that they have

“…This observation suggests that the specific antiprotozoal fungal effects of PCS or GLA-enriched microbial oil do not interfere with hydrogenesis, since methane production in experiments was not reduced (Laho et al, 2011a,b;Wencelová et al, 2014). However, it is known that PUFA sources distinctly inhibit the ruminal protozoal population, but they do not suppress bacterial activity (Hristov et al, 2004), although the reduction in the protozoal population may also lead to a decrease in the methanogen population (Toprak, 2015;Szczechowiak et al, 2016). Alternatively, the metabolic responses of rumen ciliates and bacteria to different forms and concentrations of PUFA sources vary (Cieślak et al, 2009a,b), and the absence of protozoa from the rumen microbiota did not systematically reduce methane production in the rumen environment (Morgavi et al, 2012).…”
