Available in PDF, EPUB and Kindle. Book excerpt: This bibliography was prepared for scientists concerned with the problems of defining and measuring biotic parameters, and of sampling populations in grassland communities. References on the applications of statistics to these problems, or on underlying statistical theory, are found in a great variety of publications, some limited in distribution. This is a collection of such references with abstracts and should be useful in designing new studies of grassland problems. Literature of the world through 1963 was searched; some references were undoubtedly omitted, although not deliberately.

Download or read book Forage Intake and Digestion by Fistulated Steers Grazing Range as Estimated by Chromic Oxide and Lignin Indicator Techniques written by Montie Lee Howard and published by . This book was released on 1971 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of four trials were conducted each of two summers (1964 and 1965) to estimate the digestibility of the forage dry matter, crude protein, gross energy and acid detergent fiber and estimate the daily intake of the forage dry matter, gross energy, digestible energy, crude protein and digestible protein. Two different sets of three rumen fistulated, yearling steers were used each year as the experimental animals. The diet of the grazing animals was estimated by the rumen evacuation procedure with the digestibility of this diet determined by the lignin ratio technique. Nutrient intake was estimated from the digestibility data and the fecal output was determined using chromic oxide as an external indicator.

Download or read book Determination of Intake and Digestibility of Pasture Forages Using Conventional and Indicator Techniques written by Suleyman Orhan Alpan and published by . This book was released on 1965 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digestibility experiments were carried out with dairy heifers to determine the digestibility of orchard grass, Dactylis glomerata, and also to evaluate the accuracy of various indicator techniques in pasture digestibility experiments. Chromic oxide was used as an external indicator to predict fecal dry matter output in three digestion trials. Cut grass was fed in one of the trials and corn silage in the other two. The internal indicators fecal nitrogen and protein of feed and feces were studied in two of the trials in which one conventional and one grazing trial were involved. The experimental animals consisted of six approximately two year old Holstein heifers and six Jersey heifers of the same ages. All animals were in about the fifth month of pregnancy. In the experiments, five grams of chromic oxide in gelatin capsules were fed to the animals twice a day at 7 A.M. and 4 P.M. Solka-floc, which is a pure cellulose material, was used as a carrier for chromic oxide. Fecal grab samples were collected from the rectum of grazing animals at 6 A.M. and 4 P.M. The chromic oxide recoveries in the feces of the stall fed animals fed orchard grass ranged from 98.4 to 99.2 percent, averaging 98.8 percent. The average difference between the predicted and actual fecal dry matter output was 23.1 g. This magnitude of difference yielded a 1.01 percent error of prediction. However, chromic oxide recoveries for the silage trials were considerably lower, estimated as 79.9 and 74.9 percent for trials III and IV respectively. These low recoveries of chromic oxide resulted in a rather high error of prediction of fecal dry matter output with silages. The average errors of prediction for the grass forage dry matter intakes using fecal nitrogen and protein indigestibility techniques were found to be 1.4 and -6.4 percent, respectively. The respective differences between the average actual and predicted forage dry matter intakes were 86.1 and -405.2 g. Based on the results of this study the fecal nitrogen index technique appears to be superior to the protein indigestibility technique. The digestion coefficients of ether extracts were found to be higher for the conventional trial with pasture than for that of the grazing trial, while the reverse was true for the nitrogen free extracts. The average TDN and digestible energy values for orchard grass dry matter in the conventional trial were found to be 67.1 and 68.0 percent, respectively. The difference in estimations of the TDN and digestible energy values between total collection and fecal nitrogen technique was 0.5 percent, which may be regarded as a reasonable error in digestibility experiments. The TDN and digestible energy values of the grazing trial were slightly higher than that of the conventional trial. The digestible energy determinations were highly correlated with the calculated TDN values. It was concluded that chromic oxide and fecal nitrogen may be used effectively in pasture digestibility experiments. More research is needed to establish their use as reliable indicators with single feed stuffs, such as silages, or when combined in complete rations.

This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.
