Twelve Holstein-Zebu lactating dairy cows were used to study the effects of different carbohydrate sources and soybean oil on dry matter intake, milk yield, and milk composition. The following carbohydrate sources were used: corn (CO), wheat bran (WB) or citric pulp (CP) with 0 or 2.25% of soybean oil. No significant interactions between soybean oil and carbohydrate sources were observed in this trial. Both dry matter intake (18.4 kg/day) and milk yield (23.5 kg/day) did not differ among carbohydrate sources […]

The objective of this trial was to evaluate the effects of dietary monensin and soybean oil on milk fatty acid (FA) profile in the 5th and 15th week of lactation of dairy cows. Sixteen multiparous crossbred dairy cows averaging 30 days in milk were assigned to a completely randomized block design in a 2 x 2 factorial arrangement (presence or absence of monensin and soybean oil). The following diets were used: control not supplemented with monensin or soybean oil (CT), […]

Sixteen 7/8 Holstein-Zebu multiparous cows averaging 30 DIM were used in a complete randomized block design with a 2 x 2 factorial arrangement to study the effects of supplementing monensin and/or soybean oil on production of early lactating dairy cows. The experimental period lasted 84 days and was divided in three phases as follows: I – 5th to 8th, II – 9th to 12th, and III – 13th to 16th week of lactation. The following treatments were used: control diet […]

Four rumen fistulated lactating dairy cows were assigned to a Latin Square (4×4), with 21 days of experimental period, being the last three days for evaluation, to evaluate the effects of the combination of soybean oil and monensin in lactating dairy cow diets on dry matter intake, total and partial digestibility of the nutrients and ruminal fermentation and microbial synthesis. The animals were assigned to a factorial arrangement (2×2): presence (4% in total DM) or absence of soybean oil and […]

A study was conducted to evaluate the use of cashew nuts meal (CNM) in diets for sheep, raised in feedlot. Thirty two crossbred animals received concentrates with the same amount of crude protein, but four different levels of CNM (0, 12, 24 and 36%). A factorial 4 x 2 was used, with four levels of CNM and 2 sexes, with four repetitions. Daily weight gain and feed conversion as well as intake of dry matter (DM), crude protein (CP), ether […]

The objective of this work was to verify the effects of lipid sources (ground soybean and soybean oil) added to the diet on the fatty acids profile of milk fat, specially in the increasing of CLA. Six multiparus 7/8 Holstein-Zebu cows, 30 days after calving, with average body weight of 500 kg and average milk production of 20 kg/day, were used. The animals were divided in three groups in order to receive isoprotein and isocaloric diets (treatments), in which control […]

The objective of this research was to evaluate the effects of soybean oil (500 mL/animal/day), Rumensin® (3g/animal/day) and levels of concentrate (0, 25, 50 and 75%) in the diet of bovines, and sugarcane as a forage source, in some ruminal parameters and dry matter intake. There were used four rumen fistulated 7/8 holstein-zebu steers, at 400 kg of live weight. The experiment consisted of four periods of 15 days, in which 12 were for adaptation to the diets and three […]

The objective of this work was to verify the effect of lipids sources (whole soybean meal – WSM; and soybean oil – SBO) added to the diet on changes in milk production and its physical-chemical characteristics. Six multiparous 7/8 Holstein-Zebu cows, averaging 30 days post calving, 500 kg body weight and daily milk production of 20 l were used. The animals were divided into three groups and received three isoproteic and isocaloric diets (treatments): control (3% ether extract), WSM (7% […]
