Book Description
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.

Effects of Feeding Distillers Grains Throughout a Yearling Heifer Beef Production System on Meat Quality Attributes and Effects of Omnigen - AF with Ractopamine Hydrochloride on Animal Performance and Beef Carcass Characteristics of Feedlot Steers
Author: Kelby M. Sudbeck
Publisher:
ISBN:
Category :
Languages : en
Pages : 151
Book Description
Heifers (n = 229; 225 kg ± 2) were used in a 2 x 2 x 2 factorial to determine the effects of longterm exposure to corn distillers grains plus solubles (DGS) on meat quality characteristics. Factors included supplementing 0.91 kg (LW) or 2.3 kg (HW) modified DGS (MDGS) while grazing corn stalks; 0.6% BW dry DGS (SS) daily or none (NS) during summer grazing; and finishing diet containing 40% wet corn gluten feed (CGF) or 40% MDGS (DGF) on a DM basis. An interaction was observed within CGF for discoloration, with SS increasing discoloration 30%; but no differences between SS or NS from DGF cattle. Discoloration scores for DGF increased compared to CGF d 6 - 7 and d 4 - 6 for steaks aged 7 and 21 d, respectively. Supplementing with DGS did not further reduce the color stability of retail beef of DGF finished cattle; however, DGS supplementation prior to finishing can affect beef quality when DGS are not included in the finishing diet. In the second study, crossbred steers (n = 336) were utilized in a 2 x 3 factorial evaluating duration of OmniGen – AF supplementation (0, 28, or 56 d) at 4 g / 45.5 kg BW and supplementation of ractopamine hydrochloride (RAC) at 300 mg/ steer daily for the last 28 days of finishing or no supplementation. No Omnigen – AF by RAC interaction or OmniGen –AF effects were observed for any feedlot performance or carcass characteristics measured. Supplementing RAC increased ADG 0.5 kg, increased FBW 10.0 kg, and increased LM area 0.9 cm2 compared to NORAC.

Effect of Rumen Degradable Protein in Concentrate on Cow Performance with Two Grazing Strategies in 2016 and 2017
Author: Ronald Zom
Publisher:
ISBN:
Category :
Languages : en
Pages : 61
Book Description
Two grazing experiments were carried out to investigate the effects of 1. Compartmented continuous grazing 2. Strip grazing and 3. Protein supplementation strategy (Low and High rumen degradable protein (RDP) and high RDP plus additional metabolisable protein) on pasture intake, milk and milk solids yield in spring calving dairy cows. Neither grazing system nor protein supplementation strategy influenced pasture dry matter intake. However, high RDP resulted in higher milk yield and milk protein outputs. Additional high RDP plus additional metabolisable protein did not result in further improvement of milk performance. High RDP and high RDP plus additional metabolisable protein resulted in reduced nitrogen use efficiency. Despite similar diet compositions in both experiments, there were large differences in rumen NH3 and apparent OMD between experiments, suggesting strong year to year effects in rumen fermentation and rumen digestion which were not reflected in the feeding values.
