Effects of season and plane of nutrition upon serum lipids and protein of white-tailed deer
… were collected from 80 wild deer in four areas of the southeastern United States, and from 50 captive deer on three levels of nutrition at Pennsylvania State University. Blood lipids were fractionated by thin layer chromatography; serum proteins were separated by electrophoresis on cellulose …

Evaluation of spray-dried plasma in milk replacers fed at a high plane of nutrition on performance, intestinal permeability, and morbidity
… (MR) fed at conventional rates. The use of a PP and wheat blend to replace a portion of whey protein has been shown to perform similarly to an all whey protein control MR. However, there are growing trends in the dairy industry to feed calves for accelerated growth in the pre-weaning …

Effects of prepartum plane of nutrition during mid- or late gestation on beef cow BW, BCS, blood hormone concentrations, and preimplantation embryo
… objectives were to evaluate the potential effect of prepartum plane of nutrition during mid- or late gestation on cow BW, BCS, blood hormone concentrations, and preimplantation embryos. In Exp. 1, multiparous Angus and Angus x Simmental cows (n = 33; BW = 664 ± 78 kg) were fed diets formulated to …

Effect of source of trace minerals and plane of nutrition on growth and health performance and hoof development of transported dairy calves
The aims of the present experiment were: 1) to evaluate the effects of enhanced feeding programs and trace minerals source early in life on growth and health of transported calves, and 2) to quantify the effect of early nutrition programs and trace minerals source on hoof tissue development in …

Transition cows: hepatic endocannabinoid system gene expression in response to prepartal plane of nutrition and the effects of genetic merit on genes of lipid metabolism in adipose tissue
… system gene expression in response to prepartal plane of nutrition. 2) effects of genetic merit on lipid metabolism in adipose tissue. For the objective of first experiment, we examined mRNA expression via qPCR of endocannabinoid receptors (CNR1, CNR2), enzymes that synthesize FAE (HRASLS5, …

Effects of bodyweight and plane of nutrition on mitogenic capacity of mammary extracts in cell culture, mammary growth and development, and protein expression profiles of mammary tissue in Holstein heifers
… from a large serial-slaughter Holstein heifer nutrition trial were used to determine the effects of stage of development and nutritional management on mitogenic activity of mammary extracts and mammary parenchymal composition. Stage of development and nutritional management of heifers had …

The Role of Nutrition and Administration of Estrogen in Holstein Calf Growth, Development, and Adenogenesis
… replacement heifers consumes a large portion of dairy and beef producers' income. An ultimate goal of producers is to decrease inputs and maximize outputs to produce fertile replacement heifers. Manipulating early postnatal growth and development through diet enables this practice to be …

Effects of weaning age and maternal nutrition on gene expression of longissimus muscle of beef steers
… level were studied. The longissimus muscle (LM) of beef steers on an early weaning (141 days age) plus high-starch diet (EWS) or a normal weaning (NW, 222 days age) plus starch creep-feed diet (CFS) was biopsied at 0 (EW), 25, 50, 96 (NW), 167, and 222 (pre-slaughter) days. Expression patterns of …

The role of insulin-like growth factors in the fetus
… substrate supply is important in the regulation of fetal growth. The insulin-like growth factors (IGFs), insulin and placental lactogen (PL) may be important mediators in fetal growth regulation. However, nutritional regulation of circulating concentrations of IGFs, their binding proteins …

Dietary Energy Restriction During Late Gestation in Multiparous Holstein Cows
… Holstein cows were used to determine the effects of diet, intake, and physiological state on hepatic mitochondrial camitine palmitoyltransferase (CPT) activity. In experiment 1, 30 cows were fed high grain (HG), high fat (HF), or high grain + high fat (HGF) diets from dry-off to parturition. …

Biological, Nutritional, and Processing Factors Affecting Breast Meat Quality of Broilers
A series of experiments were conducted to investigate the effects of certain biological, nutritional, and processing factors on breast meat quality of broilers. In the first experiment, the influence of genetic strain, plane of nutrition, and age at slaughter on breast meat quality was evaluated. …

Biological factors influencing the nature of goat skins and leather
The effect of a goat’s sex, age, slaughter weight and nutrition on its skin and leather quality were investigated through chemical, biochemical, histological and hydrothermal analyses of dried skins, and physical testing of leathers. This work formed part of a larger project sponsored by the …

Influence of dietary component manipulation and feed management strategies on growth and rumen development of weaned dairy heifers
… a central foundation for the continued success of the dairy industry. Emphasis on improving pre-weaned calf nutrition has predominated in the industry, but opportunities exist to improve post-weaning heifer nutrition and management. We aimed to evaluate common feed management strategies seen in …

Influence of nutrition on the muscle transcriptome and ruminal microbiome in cattle
Beef cattle nutrition research has historically focused on formulating diets to address nutrient requirements of cattle for given level of animal performance. While predictive models account for many factors that may affect nutrient requirements, additional physiological effects can alter the …

Growth Promoting Implants and Nutrient Restriction Prior to Feeding: Effect on Carcass Composition, Carcass Quality, and Consumer Acceptability of Beef
… characteristics and consumer acceptability of beef. The objectives of these studies were to determine the effect of prefinishing implant strategy and plane of nutrition on prefinishing and feedlot performance, carcass characteristics and quality, and consumer acceptability of beef. In 2 …

Estimation of economic weights for a beef cattle selection index
… computer simulation was used to estimate effect of genetic change in mature size (WMA), maximum daily milk production (PMA) and 60-d conception rate (CP) on costs per 100 kg slaughter weight (COST) and costs per 100 kg weaned weight (WNCOST) both adjusted for cull cow sales. Genetic inputs were …

Evaluation of the pathogenicity in goats of Trypanosoma Congolense from Matutuine, Mozambique
A study was conducted to determine the impact of infections with Trypanosoma congolense on various variables (including hematological and biochemical parameters) of South African Boer goats kept on various planes of nutrition. Sixteen goats with eight months old divided into four groups and …
