Effects of Milking Frequency of Dairy Goats on Milk Yield and Composition and on System Profitability
(Juniper Publishers, 2017-09)The effects of once (1X) vs twice (2X) daily milking frequency on milk yield and chemical composition of multiparous Saanen biotype goats were evaluated during the second third of lactation. Goats were assigned to one of ... -
Effects of supplementation with increasing levels of energy concentrate on the productive response and ruminal digestion of dairy cows grazing lucerne pasture
(Scientific Research, 2018-11)The aim of the study was to determine the effect of three levels of energy concentrate intake on dry matter (DM) and energy intake, milk yield and composition, rumen environment and pasture neutral detergent fiber (NDF) ... -
High pasture allowance does not improve animal performancein supplemented dairy cows grazing alfalfa during autumn–winter
(2015)The aim of this study was to assess the effect of three alfalfa pasture herbage allowances on milk yield and composition during autumn–winter grazing season on early autumn calving dairy cows. Eighteen multiparous Holstein ... -
Milk Yield and Composition and Pasture Ruminal Digestion in Grazing Dairy Cows Receiving Three Levels of Energy Concentrate Supplementation
(2017-10)The objective of the experiment was to determine the effect of feeding three levels (T3.5, T7.0 and T10.5) of energy concentrate (3.5, 7.0 and 10.5 kg cow-1 day-1) on total dry matter (DM) and energy intakes, milk yield ... -
Productive Response of Dairy Cows Fed with Different Levels of Totally Mixed Ration and Pasture
(2018-07)Forty multiparous Holstein cows in early lactation (66 ± 19 days) were assigned to one of four treatments that consisted in different ratios of total mixed rations (TMR) and pasture at 100% TMR (T0), 75:25 (T1) 50:50 (T2) ... -
