Annotation:

In the community of Tunshi San Nicols of the Licto parish in the Province of Chimborazo, an evaluation was done on the effect of an energetic supplementary feeding of bees (Italian-mestizas) during the dry season (September 23 to February 20). These supplements consisted of carrot juice (T1), orange juice (T2) and sugar cane juice (T3). These supplements were also compared to a control group (T0). The experimental units consisted of 16 standard beehives distributed randomly with the 4 treatments and 4 repetitions of each treatment. The results showed that sugar cane juice (T3) obtained the bes

Annotation:

Linseed meal (LSM) was fed to ovariectomized ewes exposed to estradiol 17-? (E2) implants over time, and LSM was supplemented to beef cows during late gestation and early lactation to evaluate the estrogenic potential of the phytoestrogen secoisolariciresinol diglycoside (SDG) found in LSM. Forty-eight ovariectomized ewes were fed a diet containing 12.5% LSM for 0, 1, 7, or 14 d and implanted with estradiol-17? (E2) for 0, 6, or 24 h before tissue collection. Uterine cellular proliferation, vascularity, and the expression of the angiogenic factors and their receptors were recorded.

Thesis (PhD (Agric))--University of Stellenbosch, 2005.<br>ENGLISH ABSTRACT: It is generally accepted that feed intake and growth (gain) are the most important economic components when calculating profitability in a growth test or feedlot. Feeding cost of animals is a major determinant of profitability in livestock production enterprises. Genetic selection to improve feed efficiency aims to reduce the cost of feeding in beef cattle production and thereby improve profitability. The objective of this study was to define a clear selection objective to enable South African beef breeders and

Annotation:

Sugar intake is linked to developmental programming of obesity and diabetes. We hypothesized that supplementing ground beef in place of sugar during pregnancy would reduce fetal and offspring developmental programming. Gestating sows were fed 1 of 4 isocaloric supplements: control, ground beef, granulated sugar, or beef plus sugar. In the fetal study supplements were fed from d 40 to 110 of gestation and in the offspring study from d 40 until weaning. Gene expression differences in fetal liver and muscle were observed for IGF2 (P = 0.04), FBPase (P = 0.03), and IGF2R (P = 0.02). Differences we

Leafy spurge (Euphorbia esula L.) is a costly noxious weed to manage in the Northern Great Plains; it invades rangelands and displaces native and desirable vegetation. Our first objective was to test the recommended full rate and half rate of selected herbicides applied in September following a spring burn on a leafy spurge invaded plant community. Our second objective was to determine if raffinate (desugared beet molasses) applied to leafy spurge invaded rangeland would attract cattle to consume leafy spurge.

Excessive dietary protein may affect MP use because of energetic costs of excreting excess N. Amino acids also may influence post-ruminal digestion. Therefore, two experiments were designed to evaluate the effects of MP intake and post-ruminal flow of AA on growth performance and pancreatic digestive enzymes. In experiment 1, treatments supplied different amounts of MP intake to cattle and the effects on growth performance and feeding behavior were evaluated. In experiment 2, duodenal infusion of glutamate or casein was examined and the effects on pancreatic enzymes were measured. Experiment 1

Cattle are social animals and frequently interact with other members of their social group, especially when access to food is limited. Despite considerable interest in the social behavior of cattle, no research has focused on assessing the relationship between competition and the feeding behavior of individual feedlot cattle housed in small groups. Forty-five British crossbred feedlot heifers (520.5 ± 32 kg BW) were used to determine how successful competitive interactions impacted an individual's ability to consume and gain access to feed in a competitive feeding environment. Heifers were ran

Assignment (MPhil)--University of Stellenbosch, 2004.<br>ENGLISH ABSTRACT: The aim of this study was to evaluate the performance and profitability of different dietary specifications for broiler chickens slaughtered at 35 days of age. Two trials were performed to evaluate different production parameters. The results of these trials were compared to the predicted results of the EFG broiler model. No carcass data were available for the two trials mentioned above. Therefore, in order to evaluate the accuracy of the broiler model when predicting carcass characteristics, two published data set

In 2006, Japan was one of the markets that contributed to the 4 million dollars live bee sales in Australia. In 2007, the export of queen honey bee from Australia was suspended when Nosema apis was detected in the nurse bees that were escorting the queens during a quarantine inspection off the Japanese ports. Nosemosis or nosema is a worldwide endemic disease caused by N. apis. Infected bees have reduced life span, energy, productivity, and develop deformed glands. As a result of this suspension, many Japanese fruit farmers had to hand pollinate many of their crops while Australian beekeepers

The aim of the first study was to determine if barley could replace maize as an energy source in concentrates fed to dairy cows grazing on kikuyu/ryegrass pasture without affecting the milk production, milk composition, or cause metabolic disorders. Sixty Jersey cows, in early to mid lactation were randomly allocated to one of five treatments (n = 12) based on feeding concentrates with different ratios of maize to barley, ranging from 100:0, 75:25, 50:50, 25:75 and 0:100, respectively. Concentrates contained 12 MJ ME kg -1 and 130g CP kg-1 DM and cows were fed 3 kg (as-is) concentrate after ea

Thesis (MScAgric)--University of Stellenbosch, 2002.<br>ENGLISH ABSTRACT: Starch is the main component of cereal grains and is usually the primary energy source for pigs and poultry. Feed manufacturing can adopt several measures, including physical treatments such as milling or pelleting and other techniques, such as enzyme treatment, to disrupt cell structure. Grinding and pelleting are the most common food processing methods used for pigs. However, pelleting of complete balanced feeds is no longer such an economical proposition due to rising energy and equipment costs; therefore this c

The biological variation in feed efficiency is regulated by multiple physiological mechanisms relevant to energy use in livestock species. The current study examined the associations between body composition, feeding behavior, linear body measurements and plasma metabolites with different measures of feed efficiency in growing heifers, finishing steers and mature pregnant cows. Our findings indicate that inclusion of body size measurements in prediction models of gain and intake improved the models? accuracy and might account important differences related to eating capacity.
