ELUCIDATING DIFFERENT CLOSTRIDIUM PERFRINGENS TYPE D VACCINE PROTOCOLS IN EWES AND LAMBS
… ETX) is a major cause of sudden mortality in lambs. Protection of neonatal lambs relies heavily on maternally derived antibodies (MDA) transferred through colostrum; however, these antibodies may also influence the lamb’s immune response to vaccination. Therefore, the present study aimed to: …

The effect of rumen inoculation on the growth rates of calves and lambs
Three commercially prepared rumen cultures and fresh rumen liquor were compared to determine their effect on the rate of gain and efficiency of feed utilization of a) twenty-four steer calves, b) twenty-four two-year old steers in pasture, and c) twelve weanling lambs. Two of the cultures were …

Methionine and glucose transport by isolated intestinal brush border membrane vesicles from pigs and lambs fed an Aspergillus product
… would influence growth or feed utilization and intestinal mucosal cell function as indicated by uptake of methionine and glucose by isolated intestinal brush border membrane vesicles (BBMV). In Experiment 1, 24 weanling pigs were paired by sex, BW, and litter and were allotted, within pairs, …

Protein supplementation and comparative feeding value of alkaline hydrogen peroxide-treated wheat straw-containing diets fed to cattle and lambs
… peroxide-treated wheat straw (AHPWS)-based diets and to compare the feeding value of AHPWS to corn silage (CS). A lamb metabolism experiment was conducted to determine the dietary CP level needed to maximize nitrogen (N) retention and fiber digestibility. Soybean meal (SBM) replaced corn to …

Early weaning and other methods of intensive lamb production
… weaning onto pasture, separate grazing for ewes and lambs on pasture, and weaned and nonweaned lambs in a drylot were compared with control groups of ewes and lambs grazed together at Blacksburg and Glade Spring in 1960 and 1961. Data were available on 457 lambs for average daily gain and …

A study of face-covering in the Hampshire breed of sheep
… covered to the nostrils. By assignment of plus and minus values for those faces considered to fall slightly above or below an event unit, ewes and lambs could be separated into fifteen classes. Some points receiving attention in the course of the study were: (1) the method of visual evaluation …

CAUSE SPECIFIC MORTALITY OF DESERT BIGHORN SHEEP LAMBS IN THE FRA CRISTOBAL MOUNTAINS, NEW MEXICO, USA
… populations of desert bighorn are declining, and factors affecting their growth rates include low lamb recruitment and high mortality of adults due to cougar predation. No one has previously reported cause-specific mortality rates for desert bighorn lambs. My objectives were to determine the …

Energy and protein nutrition of ewes in late pregnancy
Feeding of the pregnant ewe affects its weight and condition and subsequently the ability to supply the lambs with adequate nutrition. Supplementing is commonly used to secure adequate birth weight and growth rate but for efficient use the condition of the ewes as well as total composition of the …

Agronomic potential of Lupinus polyphyllus L. for dryland Merino properties in the Mackenzie Basin : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… of Lupinus polyphyllus L. (also known in New Zealand as perennial lupin and Russell lupin) as a productive pasture component for high-country pastures. To do this, a combination of on-farm studies, controlled field experiments and glasshouse experiments were carried out. Throughout the thesis, …

Lamb performance, behavior, and body temperatures in hardwood silvopasture systems
… forage-livestock systems with multiple goods and services, including shade, shelter, and browse. Reports of forage and animal productivity from these systems indicate that, in some cases, animal gains are similar or better despite lower forage yield. The relationship between grazing system, …

Chemical aspects of saponin bioactivity and ovine photosensitization diseases
… review of saponin chemistry, bioactivities and of chemical aspects of saponin-associated hepatogenous photosensitization of ruminants (sheep, goats, and cattle) is presented. A field trial was undertaken to explore the genin dose/response hypothesis that saponins produced by the plant …

The evaluation of the nutritive value of Baobab seed cake and Macadamia oil cake as feed for ruminants
Horticultural by-products such as seed and nut oil residues have the potential to replace conventional protein and energy sources in diets for ruminants. The objective of the study was to evaluate the nutritive value of Macadamia oil cake and Baobab seed cake as nutrient supplements for feedlot …

A computational approach to understanding maternal influences on the development of ruminant neonates
… because they are born immunologically naïve and agammaglobulinemic due to the synepitheliochorial placenta, which precludes the prenatal transfer of maternal immunoglobulins (IgGs) and immune cells. This vulnerability is further exacerbated by overlapping early-life health challenges, …
