Abstract:

Objectives of this study were to determine if variation in energy expenditures contributed to differences in feed efficiency between low and high RFI steers. Nine steers with the lowest and highest residual feed intakes (RFI) were selected from 169 Braunvieh-sired crossbred steers that were individually fed a pelleted roughage-based diet for 77 d. Following the RFI measurement period, heat production (HP) measurements were obtained using indirect calorimetry while steers were fed the same roughage diet (RD) and on a high-concentrate diet (CD). Linear regression analyses of log HP or retained e

Abstract:

An investigation into the effects of feed composition on lactational performance was carried out using rats and cows. A graphical representation of the feed as a triangle was used to aid the interpretation of results. The first rat experiment showed that, on high protein feeds, the lactational performance of rats is not depressed when offered feeds of very low carbohydrate content. This was substantiated by the other rat experiments. When carbohydrate in the feed was replaced by fat at low protein content (rat experiment 2) there was a large depression in lactational performance, effectively a

Abstract:

In this study the stability and nutrient removal performance of aerobic granules under variable operating pH and variable growth medium was investigated. The results indicated that alkaline pH (pH=9) inhibited nitrogen and phosphorus removal. Moreover, high pH induced granules breakage and resulted in an increased biomass concentration in the effluent. On the other hand, acidic pH (pH=6) did not have significant impacts on stability and nutrient removal efficiency of granules. Changing the growth medium from acetate-based wastewater to municipal wastewater resulted in loss of biological phosp

Abstract:

Understanding the central nervous systems role in appetite regulation is crucial to cure the obesity epidemic, which is more prevalent than any disease in the United States. Central appetite regulators, known as neuropeptides, are pivotal in understanding appetite regulation. Neuropeptide Y (NPY), a 36 amino acid peptide, plays a major role in regulating the hunger signals from the brain. In all vertebrates studied, it is a strong orexigenic neurotransmitter located throughout multiple nuclei of the hypothalamus. Peripheral hormones associated with hunger are able to activate NPY neurons in th

Abstract:

This study investigated the hypothesis that cattle fed to produce a lean carcass during a winter restriction period will subsequently grow faster and remain leaner than fatter steers during the summer, exploiting cheap grazed grass. Three studies were carried out; in the first study steers were restricted at three levels of growth (300, 600 and 900 g/day) during winter and turned out to graze grass during summer. At each level of growth during winter steers were fed on one of two diets aimed at producing steers of either a lean or fat carcass composition. At the end of the winter restriction p

In conditions where supplementation of poor quality diets is a major challenge, forage legumes such as Sericea lespedeza can be a good alternative supplement for protein at lower cost than most commercial concentrates. From studies done on Sericea lespedeza it is found plausible and valuable to supplement urea with Sericea lespedeza to strategically combat the deleterious effect of condensed tannins in the Sericea lespedeza and provide nitrogen in the rumen.

ABSTRACT Ruminal acidosis remains an important and prevalent disorder of economic and welfare concern to the dairy industry worldwide. There are inconsistencies in the diagnostic techniques and definitions of ruminal acidosis and a requirement for further information on the pathogenesis of ruminal acidosis, in particular in regard to the role of feed substrates, such as starch, sugar, and protein (Chapter 1). A greater understanding of changes to the microbiome during ruminal acidosis, feed management, and the possible synergistic effects of feed additive control agents is also required (Chapt

Selection of pigs has focussed on the improvement of lean growth with simultaneous reduction in fat tissue, due to the high economic importance of these traits.

Knowledge about the deposition rates of these components is important to accurately predict the nutritional requirements of pigs and to determine selection objectives for optimal development of body tissues and feed intake capacity.

Abstract:

Developing new membrane morphologies and modifying the existing membrane materials are required to obtain membranes with improved gas separation performances. The incorporation of zeolites and low molecular-weight additives (LMWA) into polymers are investigated as alternatives to modify the permselective properties of polymer membranes. In this study, these two alternatives were applied together to improve the separation performance of a polymeric membrane. The polycarbonate (PC) chain characteristics was altered by incorporating p-nitroaniline (pNA) as a LMWA and the PC membrane morphology wa

Abstract:

O objetivo deste estudo foi avaliar o fornecimento crônico de leptina recombinante ovina (oLeptina) e do nível de energia da dieta na idade, peso vivo (PV), escore de condição corporal (ECC) e composição corporal à puberdade, assim como avaliar seus efeitos no desenvolvimento dos folículos ovarianos e no consumo de matéria seca (CMS). Foram utilizadas 36 novilhas da raça Nelore, com média de 18 a 20 meses de idade, 276,1 ± 17,9 kg PV e ECC de 4,7 ± 0,46, distribuídas aleatoriamente em três tratamentos: A) Dieta de alta energia; B) Dieta de baixa energia, BL) Dieta de baixa energia com administ

Abstract:

Foi realizado um experimento de suplementação com bezerras Nelore, em pastagem de Brachiaria brizantha cv. Marandu, no período de transição seca-águas. Os tratamentos foram suplementação com sal mineral com 65 g de fósforo/kg (SM), sal mineral com 65 g de fósforo/kg + 1500 mg de virginiamicina/kg (SMV), sal proteinado com 40% de proteína bruta (SP) e sal proteinado com 40% de proteína bruta + 638 mg de virginiamicina/kg (SPV), em três ciclos de pastejo (CP) de 35 dias cada. O método de pastejo adotado foi rotacionado com sete dias de ocupação e 28 dias de descanso. Foram realizadas as seguinte

Abstract:

Ewes at two sites were fed to be either condition score 2 or 3 by Day 90 of pregnancy and then grazed on various levels of feed-on-offer (FOO) from Day 90 of pregnancy until weaning, to investigate whether nutrition of Merino ewes during pregnancy and lactation affected the muscle, fat and immunity to worms of their progeny. Eye muscle and fat depth at the C-site, and faecal worm egg counts (FWECs) of the progeny were measured between 7 - 27 months of age. Ewe condition score at day 90 of pregnancy did not impact largely on the eye muscle depth, fat depth or FWEC of the progeny. Increasing FO
