“…Sunflower as a forage source is reported to be high in fiber and low digestibility (Demirel et al 2009) compared to other forages. Forages with high fiber content reduce the digestibility of the ration, the synthesis of rumen microbial protein and the supply of energy (Gottardo et al 2017).…”

“…It is medium quality forage due to its high fibre content and lower digestibility resulting in negative effects on intake (Demirel et al, 2006). Ensiling may be difficult due to low dry matter (DM) content that together with a medium protein content does not lower pH rapidly (Demirel et al, 2009). Given its medium quality, the recommended proportion for inclusion of sunflower silage in diets for dairy cows varies among authors, who coincide that, due to its limitations, is not viable as an only source of forage (Tan et al, 2014;Aragadvay-Yungán et al, 2015).…”

Small-scale dairy systems are an option to ameliorate rural poverty in developing countries. These systems need to enhance their productivity through improved feeding strategies. The objective was to assess in a participatory on-farm experiment the effect on dairy cow performance of the inclusion of sunflower silage (SFS) with maize silage (MSL) during the dry season in three treatments: T1= 100% MSL, T2= 50% MSL/50% SFS, and T3= 75% MSL/25% SFS. Cows grazed 8 h/day, received 6.8 kg DM/cow/day of silage treatments, and 4.6 kg DM/cow/day of commercial concentrate (as decided by the collaborating farmer). Design was a 3x3 Latin Square replicated three times with nine Holstein cows, and 14-day experimental periods. Analysed variables were milk yield and composition, live weight and body condition score; as well as chemical composition of feeds and feeding costs. There were significant differences with a higher milk yield and higher milk fat content in T2 than T1 with intermediate values for T3; but no significant differences for protein (mean 31.4 ± 6.1 g/kg), lactose (45.1 ± 3.4 g/kg), pH (6.5 ± 0.16) or milk urea nitrogen (10.5 ± 0.81mg/dL). There were highly significant differences in live weight with T3 recording a lower live weight than T1 or T2, but no differences between treatments for body condition score (mean 2.3). Feeding costs were lowest for T2 and highest for T1. The inclusion of SFS at 50% with MSL to complement grazing dairy cows of moderate milk yields is an alternative to increase milk yields and income in small-scale dairy systems.
