Effects of feeding rations with genetically modified whole cottonseed to lactating Holstein cows.
Two experiments were conducted to evaluate dry matter intake (DMI), milk yield, and milk composition from feeding rations that contained different sources of genetically modified whole cottonseed to Argentinean Holstein dairy cows. Twenty-four lactating multiparous Argentinean Holstein dairy cows were used in 2 experiments with a replicated 4 x 4 Latin square design, with cows averaging 565 kg ...
متن کاملDigestibility and effects of whole cottonseed fed to lactating cows.
Four lactating Holstein cows producing about 21 kg milk/day were fed complete rations containing 0, 5, 15, and 25% whole cottonseed in a 4 X 4 Latin square design. Diets were fed ad libitum. Periods were 21 days in length with total collections of feces and urine during the last 7 days of each period. Digestibilities o nitrogen, lipid, and energy increased with increasing cottonseed in the diet...
متن کاملPerformance of lactating dairy cows fed whole cottonseed coated with gelatinized cornstarch.
The handling characteristics of whole cottonseed are improved by coating with gelatinized cornstarch, but limited information is available on the effects of feeding the coated cottonseed to lactating dairy cows. Thirty-six lactating Jersey cows were used in a crossover design trial with 4-wk experimental periods to evaluate the influence of coating whole cottonseed with 2.5% gelatinized cornsta...
متن کاملEffects of long-term feeding of genetically modified corn (event MON810) on the performance of lactating dairy cows.
A long-term study over 25 months was conducted to evaluate the effects of genetically modified corn on performance of lactating dairy cows. Thirty-six dairy cows were assigned to two feeding groups and fed with diets based on whole-crop silage, kernels and whole-crop cobs from Bt-corn (Bt-MON810) or its isogenic not genetically modified counterpart (CON) as main components. The study included t...
متن کاملEffect of Feeding High Free Fatty Acid Whole Cottonseed on Milk Yield and Composition of Lactating Dairy Cows
Several criteria are used for determining the acceptability of whole cottonseed (WCS) for crushing including concentrations of moisture, oil, free fatty acids in the oil (FFA), and ammonia. Whole cottonseed that does not meet the minimum standard is typically sold as a feed ingredient. When tropical storms delay cotton harvest and the moisture remain elevated, concentrations of FFA increase. Fe...
