Book Description
The impetus for sorghum (Sorghum bicolor L.) silage to replace corn silage in beef cattle and dairy rations has increased due to sorghum's ability to grow well under water-limited conditions. Two experiments were conducted to evaluate the effects of maturity, mechanical processing, ensiling duration, and hybrid on in situ ruminal digestibility. In Exp. 1, three ruminally cannulated beef steers (BW = 463 ± 15 kg) were used to evaluate the effect of maturity stage, mechanical processing, and ensiling duration on in situ digestibility of forage sorghum silage. A brown midrib (BMR) forage sorghum (Alta Seed AF7401) was harvested at soft dough (SD) and hard dough (HD). Within each maturity stage, sorghum kernels were processed (C) using a chipper shredder or left unprocessed (W), and were subjected to 0, 30, 60, or 120 d of ensiling. In Exp. 2, three ruminally cannulated steers (BW = 570 ± 17.9 kg) were used to evaluate sorghum hybrids and ensiling duration on in situ silage digestibility. A BMR forage sorghum (Alta Seed AF7401), conventional forage sorghum (Sorghum Partners NK300), and a grain sorghum (Sorghum Partners SP33S40) were ensiled for 0 or 60 d, which was the optimal ensiling duration for Exp. 1. In Exp. 1, kernel processing increased (P

Book Description
Ensiling is a technique that is used to store food, mainly vegetable crops, to feed the herd when the forage supply from the pastures is not enough to maintain the productive performance of the ruminant animals. However, silage can also be used as substrate for biogas production and other different purposes. In the past years, we have seen many advances in the knowledge about silage production utilization, and this book is a compilation and discussion of the outstanding scientific research activities concerning actually the most recent advances and technologies that have been studied about silage and future demands. It is directed to a broad public of readers - farmers, academics, students, or anyone just curious or interested in the subject.

Book Description
Provides a historical foundation as well as a review of the state-of- the-art in forage science, detailing 25 years of progress in forage quality, evaluation, and utilization, along with the latest developments and new directions for future research. The volume is divided into six sections: overview of forage science; identification and quantitative measurement of forage quality components; intake as a critical element of forest quality; role of digestion and metabolism in determining forage quality; integrating concepts affecting changes in forage quality; and improving forage quality and evaluation.

Book Description
This book is an officially authorized advisory manual that implements the recommendations on the energy and protein requirements of cattle, sheep and goats made by the AFRC Technical Committee on Responses to Nutrients (TCORN) since its establishment in 1982. TCORN has produced a series of numbered reports including No. 5 in 1990 on Nutrient Requirements on Ruminant Animals: Energyand in 1992, No. 9 Nutrient Requirements of Ruminant Animals: Protein. The former recommended, with only minor modifications, the adoption of the AFRC’s 1980 Technical Review’s full recommendations on energy requirements of ruminants, while the latter recommended the adoption of a protein system based on Metabolisable Protein as the unit. Opportunity has been taken to include material from TCORN Report No. 8, 1991 on the Voluntary Intake of Silage by Cattle and from an unpublished TCORN Report on the Nutrition of Goats. The current volume presents these recommendations in a practical form designed for use by advisors, farmers, lecturers, research workers and students concerned with the nutrition of ruminant animals. The manual includes 45 tables of requirements (incorporating agreed safety margins) and 29 example diets.
