Effects of tallow supplementation on dietary nutrient and minimal amino acid utilization in the laying hen were studied in two experiments. In the first experiment diets contained six levels of animal tallow ranging from 0 to 10%. Percent egg production and egg mass were not significantly affected by tallow. Body weight was significantly increased by 2% tallow was maximum at 6%. Addition of up to 6% fat improved feed conversion without adversely affecting other production characteristics. Metabolizable energy (ME) intake increased from 305.1 to 322.4 kcal/hen/d over the range of 0 to 6% tallow

Introduction : Family Poultry (FP) are birds of indigenous breeds living in almost symbiotic relationship with human communities. The chickens are usually free ranging, or have very limited restrains on their access to the village environment. African livestock population statistics for 1995 indicates poultry to be the most numerous species of farm animal (Anonymous, 1996a). More than 80% of poultry are kept in rural areas and contribute substantially to annual egg and meat production (Sonaiya, 1997). Throughout Africa poultry production stems from ancient traditional practices. FP is the most

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

Annotation:

Determining the energy values of feed ingredients for poultry is of great concern, especially since production efficiency is associated with profit margins. Therefore, accurate, precise, and reproducible energy values for feed ingredients are of the utmost importance in formulating an economical diet. An important aspect in determining the apparent metabolizable energy (AME) of a feed ingredient is the procedure employed in the drying of excreta samples. During sample preparation, substantial grinding losses were incurred amounting to 3.5 to 5.2% of the dried sample weight. Also moisture upta

Intragastric intubations of tryptophan inhibited food intake and decreased body temperature of SCWL cockerels.

[Truncated abstract] Australia produces 87% of the worlds lupins (Lupinus angustifolius) which have the potential to be an excellent source of protein and energy in animal diets. However, feed manufacturers and poultry producers cannot use more than about 5% lupins in broiler and 7% in layer diets. The main reason is because 34% of the lupin grain comprises complex cell-wall polysaccharides that are indigestible. The main component of cell walls in lupins is pectin (33%). Poultry cannot digest pectin because they don't secrete the appropriate enzymes so their ability to use lupins is limited.

Creation of the feed: This proceeded from the cultivation, cutting, and drying of amaranth until the obtaining of the flour and late

Bibliography: leaves 107-130. This study evaluates quality of fermentation of the silage and also its nutritive value to ruminants on the basis of "in vitro" and "in sacco" digestability. Animal response to the silage is also evaluated in an "in vivo" digestability and nitrogen balance trial with Australian Merino sheep. The objective of this thesis is to investigate the opportunities for utilising citrus pulp and poultry litter to improve the nutritive value of wheat straw.

Thesis (MScAgric)--Stellenbosch University, 2011.<br>ENGLISH ABSTRACT: The objective of this study was to evaluate the use of Musca domestica (common house fly) larvae meal, as protein source, for broiler production. This was done by investigating the nutritive value of house fly larvae meal together with its total tract digestibility, potential toxicity and carcass characteristics of the broilers supplemented with house fly larvae meal. The proximate analysis of house fly larvae meal show that it contained, on a dry matter basis, a gross energy value of 20.10 MJ/kg, 60.38% crude protein,

Master of Science<br>Department of Animal Sciences and Industry<br>R. Scott Beyer<br>The modern poultry industry uses auger feed lines to transport feed for broilers to pans to make feed available for them while greatly reducing labor costs. The feed given to broilers is manufactured at significant cost into a pelleted form. Pellets reduce broiler production costs by increasing feed intake and growth rate while reducing feed. Pellet quality is expressed using a method called the Pellet Durability Index (PDI). A series of studies was conducted to determine the effects of these destructive

Several experiments were conducted to identify the limiting amino acids in a 22% corn-soybean meal diet for poults from one to three weeks of age. Additional studies were designed to investigate changes in muscle composition and protein turnover in response to essential (EAA) and nonessential amino acid (NEAA) supplementation of the low protein diet. Developmental changes in muscle metabolism as well as differences between muscles were also examined. Protein synthesis was determined using a ¹⁴C-tyrosine emulsion technique. Protein degradation was calculated as the difference between synthesis

Annotation:

There is a growing market for specialty poultry production using alternative genotypes and management systems. However, producers interested in specialty poultry production face several challenges. One challenge is that little published data exists regarding the growth and production parameters for alternative genotypes like slow-growing meat strains and heritage breeds. To address this challenge, research at the University of Kentucky examined the effect of feed strategies, alternative feedstuffs, and dietary enzymes on the growth and performance of heritage breeds of chicken used for either
