“…Phipps et al (2000) administered doses of monensin (0, 150, 300, and 400 mg/d) and did not observe differences in DMI. Similar to the present study, previous works did not find effect of the thermal process in DMI (De Marchi et al, 2013;2015). Blood parameters are health indicators that can show the nutritional status and can be used to diagnose metabolic disorders.…”

El peletizado y la monensina sódica incrementan la concentración de CLA en leche de vacas suplementadas con linaza Peletização e monensina sódica aumentam a concentração de CLA no leite de vacas alimentadas com linhaçaAbstract Background: Demand for naturally enriched foods is increasing worldwide. Animal nutrition allows incorporating nutraceutical molecules into milk. These molecules are intended for improving human health. Objective: To evaluate the effects of pelleting and monensin addition to the diet on intake, digestibility of dry matter (DM) and nutrients, milk yield and composition, and fatty acids (FA) profile in cows kept on pasture and supplemented with concentrate containing ground flaxseed (GF). Methods: Four Holstein cows were assigned to the following treatments: 1) concentrate with GF; 2) GF + 32.93 mg/Kg monensin (GFM); 3) GF pelleted (GFP); 4) GF pelleted + 32.93 mg/Kg monensin (FMP). Results: Treatments did not show effects on digestibility of dry matter (DM) and nutrients or feed intake, with the exception of ether extract intake, which was reduced by 28% with pelleting. Addition of monensin increased the conjugated linoleic acid (CLA) concentration by 47%. Pelleting increased the concentrations of CLA (70%), polyunsaturated FA (PUFA; 25%), Rev Colomb Cienc Pecu 2018; 31(2):110-119Vieira Romero J et al. Pelleting and monensin increase milk CLA and monounsaturated FA (MUFA; 16%), and reduced the concentrations of steric acid (C18) in 19% and total saturated FA (SFA; 14%). Conclusion: Pelleting and monensin does not alter feed intake and digestibility of DM and nutrients. Pelleting of concentrate feed containing flaxseed improves milk FA quality. ResumenAntecedentes: La demanda por alimentos naturalmente enriquecidos se ha venido incrementado en todo el mundo. A través de la nutrición animal es posible incorporar moléculas nutracéuticas en la leche. El uso de estas moléculas pretende mejorar la salud humana. Objetivo: Evaluar los efectos de la peletización y la monensina sobre la ingesta, digestibilidad de la materia seca (DM) y nutrientes, producción de leche, composición y perfil de ácidos grasos (FA) en leche de vacas en pastoreo que consumen alimento concentrado formulado con linaza molida (GF). Métodos: Cuatro vacas Holstein fueron distribuidas en los siguientes tratamientos: 1) ración conteniendo GF; 2) GF + 32,93 mg/Kg de monensina (GFM); 3) GF en pellets (GFP); 4) GF en pellets + 32,93 mg/Kg de monensina (FMP). Resultados: Los tratamientos no mostraron efectos en el consumo y digestibilidad de la DM y nutrientes, excepto por el consumo de extracto etéreo, con una reducción del 28% en las raciones peletizadas. La monensina incrementó la concentración de ácido linoleico conjugado (CLA) en 47%. La peletización aumentó el contenido de CLA (70%), FA poliinsaturados (PUFA; 25%) y FA monoinsaturados (16%); y redujo las concentraciones de C18 en 19%, y FA saturados total en 14%. Conclusión: El peletizado y la monensina no alteran la ingesta de alimento ni la digestibilidad de la DM y nutrientes...

“…The study revealed that TDN had not been influenced by giving dairy cattle with EEG. This result agreed with the reults reported by Marchi et al (2013) that pelleting and lignosulfonate treatments influenced diet intake and nutrient digestibility but were not affected by ground seeds. Additionally, TDN intake influenced CF, which is a source of roughage used in the diet was corn silage similar to diets based on a combination of two roughages (Alessio et al, 2018).…”

The growth of several types of grass in the area of mine re-vegetation is rapidly providing an opportunity to be used as forages despite the possibility of heavy metal contamination. The purpose of the study was to evaluate the effect of treatment of different levels of elephant grass (EG) (Pennisetum purpureum) planted at ex-coal mining reclamation on milk productivity and mineral contents of dairy cattle. This study used four lactating (second lactation) dairy cattle using Latin Square Design of 4 (treatments) x 4 (replications). Each period was 21 days consisted of 14 days of preliminary for feed adaptation and 7 days for observation. Treatments were P0 (0% ex-coal mining (EEG)+60% Farmer's EG (FEG)+40% Concentrate), P1 (15% EEG+45% FEG+40% Concentrate), P2 (30% EEG+30% FEG+40% Concentrate), and P3 (60% EEG+0% FEG+40% Concentrate). The study observed variables of feed intake and efficiencies, milk production, milk quality, and mineral contents of milk. Results showed that EEG treatment at different levels did not affect fresh and dry matter intake. The highest fresh and dry matter intake was found in P0 treatment. There was no significant difference in giving EG planted at the ex-coal mining and the farmer's land on the milk production and milk quality. The only significant differences (p<0.05) were found in mineral Fe and Mg contents of milk. The study concluded that giving EG planted at the ex-coal mining area until 60% of forage affected Fe and Mg contents of milk, but they are still in the safe limit.

“…However, lignosulfonate and pelleting could contribute to release of oils in the rumen, improving the digestibility of nutrients and the milk production of dairy cows. Thus, studies to minimize the negative effects of high fat addition and increase PUFA uptake in milk are important to improve the impact of sunflower seeds use on ruminant nutrition (Marchi et al, 2013).…”

The objective of this study was to evaluate the fatty acid composition of butter from Holstein cows fed diets containing ground sunflower seeds or ground and pelleted sunflower seeds, with or without the addition of lignosulfonate. The butter was produced from milk collected from eight Holstein cows multiparous, with 100±62.6 days in milk, with a mean weight of 556±39.8 kg Body Weight (BW) and producing 15.6±0.12 kg of Milk/day. The cows were distributed in a double Latin square, with 4 periods of 21 days each, with 14 days for adaptation and seven days for data collection. Diets containing pelleted sunflower seeds altered the fatty acids profile of the butter, with an increase in the fatty acids 16:1n-11, 18:1trans and CLA18:2 c9 t11. However, decreased the amounts of fatty acids 18:0 and 20:0. The amounts of Saturated Fatty Acids (SFA) decreased, while the Polyunsaturated Fatty Acids (PUFA) and the amount of total Conjugated Linoleic Acid (CLA) increased with the pelleted diet. Thus, the use of diets with pelleted sunflower seeds is possible to obtain butter with desirable nutritional value in dairy products, which are beneficial for consumer health.
