Supplementation of apple pomace with nonprotein nitrogen for gestating beef cows. IV. Pesticide accumulation in cows.
Samples of fresh apple pomace were collected from 14 loads of apple pomace as delivered from the processing plant in October 1968 and from stored apple pomace that had been obtained in October 1967 and fed during a feeding trial from mid-November 1967 through April 1968. All samples were analyzed for dicofol (kelthane), tetradifon (tedion), DDT, DDD and DDE. For the pesticide residues in fresh ...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Utilization of nitrogen in cows consuming wet distillers grains with solubles in alfalfa and corn silage-based dairy rations.
The objectives of this experiment were to determine the effects of forage type on nutrient digestibility, purine derivative excretion, nitrogen utilization, and milk production in dairy cattle consuming rations containing high levels of wet distillers grains with solubles (WDGS). Primiparous (n=8) and multiparous (n=20) Holstein cows were used in a replicated 4 x 4 Latin square. Animals were fe...
متن کاملComparative Study on Milking Ability of Sahiwal Cows and Murrah Buffaloes under Hand and Machine Milking
Present study was undertaken to compare the effect of two different milking methods (hand vs. machine milking) on milking ability in Murrah buffaloes and Sahiwal cows. 30 lactating Sahiwal cows and 30 lactating Murrah Buffaloes were selected and divided into four equal groups having 15 animals each. 15 animals of each species were subjected to machine milking and 15 animals of each species were...
متن کاملSupplementation of apple pomace with nonprotein nitrogen for gestating beef cows. II. Skeletal abnormalities of calves.
Skeletal abnormalities consisting of shortened long bones, enlarged joints and splayed front feet in newborn calves were associated with cows fed apple pomace supplemented with nonprotein nitrogen (NPN) during late gestation. Measurements of x-ray films of the metacarpus and lumber vertebrae from 86 calves in three trials showed that calves from dams fed apple pomace and NPN had longer, thicker...
