Environmental and Economic Responses to Precision Feed Management in Dairy Cattle Diets
نویسندگان
چکیده
The dairy industry is under pressure to reduce its environmental impact while producing more milk meet society’s needs. Precision feed management (PFM) one tool that can be used this challenge. A simple definition of PFM provide adequate, but not excessive, nutrients animal requirements. There has been an trend decrease diet nitrogen (N) and phosphorus (P) in the last 20 years. New York herds lowered N by 10.8% between 1999 2019. Milk per cow increased 40% during time, total manure excretion decreased 8.1%. Research results from on-farm trials have consistently indicated lowering crude protein (CP) decreases improving profitability; a 3-year study with 8 herds, CP was 9.7%, 14% lower. Income over purchased cost $137/cow/year. Carbon footprint (CF) also decreased. 19% 2007 2017 reported for United States industry. already made significant strides production on environment; however, there are additional opportunities further nutrient emissions into environment increase efficiency use.

Yeast in Dairy Cattle Diets
Yeast is a unicellular fungi that does not reproduce via asexual spore production (Phaff, 1966). The most commonly fed yeast in dairy diets is Saccharomyces cerevisiae (SC); a facultative anaerobic yeast often referred to as brewers or bakers yeast. The most common yeast products fed to ruminants are live cells or yeast culture mixtures. A yeast culture is a yeast-fermented product that contain...

This study was conducted to investigate the effect of dairy cow diets containing different protein sources [soybean meal, xylose protected soybean meal (Yasminomax®), and steam-flaked whole soybean] and various partially processed grain on in vitro gas production kinetics and the microbial nitrogen yield. Soybean meal (S) and xylose protected of soybean meal (XS) were provided as 0.56:...

Periparturient hypocalcemia or milk fever is a common condition of dairy cows with an annual incidence of 5 to 8%. Feeding rations with low dietary cation-anion difference (DCAD) to dairy cows for at least 2 weeks before calving decreases the incidence of periparturient hypocalcemia (Ender et al 1971, Dishington 1975, Block 1984, Oetzel et al 1988, Lean et al 2006, Goff 2008). The most likely r...
متن کاملFeed management practices to reduce manure phosphorus excretion in dairy cattle
Phosphorus (P) is an essential mineral that needs to be supplied in sufficient quantities for maintenance and growth and milk production in dairy cattle. However, over 60% of the P consumed can be excreted in faeces with a potential to cause environmental pollution. Concern over higher levels of P in intensively managed livestock systems has led to legislation such as the Water Framework Direct...
متن کاملEconomic values of live weight and feed-intake capacity of dairy cattle under Dutch production circumstances
This study estimated the effect of genetic change of live weight (LW) and dry-matter intake capacity (DMIC) on labour income (economic values) in dairy cattle under different production circumstances. Dutch production circumstances in the years 1998 and 2008 were based on different scenarios and varied with respect to product prices, milk output restrictions and environmental legislation. Linea...
