TL;DR
This study explores feeding practices in Brazilian dairy farms and finds that high and medium milk-producing herds use better feed management techniques than low-producing ones.
Contribution
The study provides new insights into how feeding practices vary with milk production levels in Brazilian confined dairy systems.
Findings
High and medium production herds are more likely to evaluate feed quality and use cooling systems.
High production herds have better feeding frequencies and management practices.
Low production herds show less frequent use of advanced feeding management techniques.
Abstract
Despite the critical role that feeding and feed bunk management practices play in dairy herd performance, limited information is available on how these practices are implemented across different production levels in Brazilian confined dairy systems. We aimed to gather information on the producers ‘reported feeding practices used on confined dairy operations and identify their relationship with average herd milk production. An electronic survey of 38 questions was emailed to 500 Brazilian dairy producers. Out of the 135 responses received, answers from 82 producers were included, and herds were ranked according to their 305-d milk production (kg) as low (LP; < 7,000; n = 27), medium (MP; 7,000–10,000; n = 35), and high production (HP; > 10,000; n = 20). The HP and MP herds had greater odds of evaluating particle size distribution, forage DM, TMR physically effective fiber NDF (peNDF),…
