Book excerpt: A 2-yr experiment was conducted researching the impact of common lower Midwestern beef cattle winter forage systems on late gestation, spring-calving beef cows and their subsequent calves. We hypothesized that cows grazing stockpiled tall fescue (STF) during late gestation would have increased nutrient intake compared to cows fed summer-baled tall fescue hay (HAY), which would result in improved fetal growth and development, as well as subsequent calf performance and metabolic status. Overall, cows consuming HAY lost more BCS prepartum than cows consuming STF. In yr 2 HAY cows gained more BW prepartum than STF cows, but there was no difference between forage systems in yr 1. Calves born to cows consuming HAY weighed less at birth than calves born to STF cows, suggesting decreased fetal growth. Despite this, in yr 2 there were no differences in calf vigor measures at birth or in triiodothyronine, thyroxine, or cortisol concentrations at 48 h. Additionally, calves born to HAY cows tended to weigh less at d 80 than STF in yr 1, but in yr 2 there was no difference. During yr 1 blood urea nitrogen (BUN) was greater at 48 h for calves born to cows consuming STF and plasma glucose concentrations tended to be greater through weaning for STF calves. Despite this, impacts of late gestation maternal nutrition on calf amino acid concentrations at 48 h varied. In conclusion, grazing stockpiled tall fescue in late gestation appears to improve fetal growth and alter perinatal nutrient supply in calves.

Available in PDF, EPUB and Kindle. Book excerpt: A four year study (2004-2007) was conducted at Highland Rim Research and Education Center near Springfield, TN to compare tall fescue (Lolium arundinaceum Schreb.) forage systems in which rye (Secale cereale L.)/ryegrass (Lolium multiflorum Lam.) was used to supply additional high quality forage to stocker cattle. Twelve 1.2-ha pastures were assigned to two cool-season forages and two forage systems with three replicate pastures each. Cool-season forage treatments were: (1) endophyte-infected (Neotyphodium coenophialum) 'Kentucky-31' tall fescue and (2) 'Jesup MaxQ'[Superscript TM] tall fescue. The two forage systems were: (1) stockpiled tall fescue, supplemental feed (a blend of byproduct feeds formulated to provide energy and protein equivalent to tall fescue hay) during winter, spring growth tall fescue and (2) stockpiled tall fescue, rye/ryegrass during winter when available, spring growth tall fescue and rye/ryegrass. Forage systems containing rye/ryegrass were established by drilling 38 kg of rye and 6.8 kg ryegrass in a prepared seedbed in 0.4 ha of the allotted 1.2 ha pasture area. All pastures were clipped in late spring to assure vegetative growth. In late-November, four weaned beef steers were randomly allotted to each pasture based on age, weight, and breed and remained on pastures until mid to late June. Steers grazed rye/ryegrass when it reached average height of 20 cm and were removed at an average height of 8 to 10 cm. Forage heights of rye/ryegrass before and after grazing and the number of days grazing was recorded. When forage was unavailable or insufficient, cattle were fed a byproduct-based supplement. Animal weights were collected on two consecutive days at the beginning and end of the trial. Data collected at 14-d intervals included: steer weight, forage availability by clipping strips (2 per 0.4-ha pasture), and blood serum for prolactin. Data were analyzed using the MIXED procedure of SAS and differences determined at P

Available in PDF, EPUB and Kindle. Book excerpt: Bovine Reproduction is a comprehensive, current reference providing information on all aspects of reproduction in the bull and cow. Offering fundamental knowledge on evaluating and restoring fertility in the bovine patient, the book also places information in the context of herd health where appropriate for a truly global view of bovine theriogenology. Printed in full color throughout, the book includes 83 chapters and more than 550 images, making it the most exhaustive reference available on this topic. Each section covers anatomy and physiology, breeding management, and reproductive surgery, as well as obstetrics and pregnancy wastage in the cow. Bovine Reproduction is a welcome resource for bovine practitioners, theriogenologists, and animal scientists, as well as veterinary students and residents with an interest in the cow.

Book Synopsis Lactation and the Mammary Gland by : R. Michael Akers
Download or read book Lactation and the Mammary Gland written by R. Michael Akers and published by John Wiley & Sons. This book was released on 2016-02-10 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Michael Akers provides the basics for understanding mammary development and lactation and conveys the critical regulatory events in lactation. This text willl prove to be an invaluable overview of mamorary development and lactation for undergraduates and graduates studying lactation, new researchers, and as a review for established scientists. Additionally, the book will be an important resource for professionals in the animal and dairy industry and for those in other scientific disciplines such as food chemistry, cell biology, and endocrinology whose work is closely tied to mammary gland development and function. Lactation and the Mammary Gland covers growth and development of the mammary gland including comparisons between species. It imparts and emphasizes the critical nature of mammary growth and the onset of lactation at the time of parturition. Special emphasis is given to the endocrine and growth factor regulation of both mammogenesis and lactogenesis. A thorough discussion of the role of growth hormone in development and maintenance of lactation or galactopoiesis adds to this book's value as a text and reference. The author reviews the presence of hormones, growth factors, and other bioactive compounds in milk and mammary secretions as well as the potential for use of the mammary gland as a bioreactor in the pharmaceutical industry. A description of the nutritional and management factors in milk production round out the book's comprehensive coverage.

There are new chapters onsurgery, embryo transfer, artificial insemination, ethno-veterinarymedicine and biosecurity, and a new consolidating chapter on theinteraction between the animal, environment, management anddisease. The previous edition has sold all over the world, and as aresult of this a greater emphasis has been placed on conditions andtheir treatment in areas other than temperate regions. A newsection entitled "Global Variation in Cattle Practice" has beenincluded with contributors discussing bovine medicine practice intheir part of the world. All in all this is an outstanding resource for any practisingvet and an excellent reference for veterinary students.
