Impact Of Drinker Type On Pig Performance, Water Use And Manure Production, Mike Brumm, Jill Heemstra

Nebraska Swine Reports

A summer experiment was conducted to examine the impact of drinker design on pig performance, water use and manure volume. Pigs with access to Drik-O-Mat® bowl drinkers had similar daily gains, lower feed intake and improved feed conversion compared to pigs with access to a WaterSwing® nipple drinker. Water use was reduced 24.8 percent for the bowl versus swing drinkers. Manure volume was reduced 21.6 percent for the bowl versus swing drinker. The difference in manure volume is most likely due to a reduction in water wastage. Selection of drinker devices must include consideration of the manure system design and …

Response To Increasing Levels Of Nutrients Fed During Gestation And Lactation To Control And Prolific Gilts, David Casey, Rodger K. Johnson

Nebraska Swine Reports

Normal diets and diets with 50 percent greater amounts of protein, vitamins and certain minerals were fed during the gilt development period through lactation to gilts of lines that differed in litter size. The lines had been developed with 10 generations of genetic selection that resulted in a difference between the prolific line and a randomly selected control line of 2.9 fully formed pigs at birth in first parity sows. However, the large litter size line also had greater numbers of stillborn pigs, smaller pigs at birth and greater pre-weaning mortality. The purpose of the experiment was to determine whether …

Improving Feed Grains, Bruce P. Mullan

Journal of the Department of Agriculture, Western Australia, Series 4

Clearly, to encourage grain growers to focus their production systems towards feed grains, it is important to first identify the reasons for variation in the nutritional value of grains and then to develop rapid, cheap, and accurate methods of measuring these factors. The analytical methods should ideally be suitable for application either at the site of grain delivery from the farm or within the place of stockfeed manufacture. This will mean the nutritional value of the grain can be known before it is used. The rational marketing of feed grains could then be achieved, with the benefits from more efficient …

The normal span of feeding of these larvae were 8 days which was considered as control. A lot of larvae mortality occured due to feeding for 1 and 2 days therefore, these treatments were not considered. …

The Importance Of \Omega-3 Series Fatty Acids In Marine Fish Larvae Nutrition And Recent Developments, Abdurrahman Polat, Gülsün Özyurt

Turkish Journal of Veterinary & Animal Sciences

In general, marine fish larvae require \omega-3 HUFA, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Larval growth, survival and larval activity are affected by dietary levels of essantial fatty acids. Some pathological signs, such as abnormal pigmentation, hydrops etc. and low feed conversion efficiency, poor growth, mass mortality are related to \omega-3 HUFA series fatty acids deficiency in larvae food. EPA/DHA ratio in live foods or microencapsuled diets is an important factor in larval development and survival.

Fisheries Research Report No. 112 - Final Report, Frdc Project 94/075: Enhancement Of Yabby Production From Western Australian Farm Dams, Fisheries Western Australia, Fisheries Research And Development Corporation

Fisheries Research Reports

Farmers receive higher prices per kilo for large yabbies. Yabby farmers have reported that the majority of yabbies trapped from farm dams are below market size (< 30 g) and therefore of no economic value. In addition, farmers also report that while dams produce large yabbies when first harvested, after a number of years the proportion of large animals gradually decreases.

To identify why yabbies in farm dams stunted and how farmers could increase the size of small yabbies the project had three main experimental areas.

Research station experiments: A field research station consisting of 25 ponds was constructed for running replicated, randomised and reproducible experiments, with controls, in an environment that simulated farm dams. In addition, these ponds were large enough to provide an adequate sample number of yabbies at realistic industry stocking …

Protein Production In The Milk Of Genetically Engineered Animals, Katherine M. Bates

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are numerous proteins that have potential uses in commercial and scientific applications that are not utilized to their full potential. this is partly because it is not economically feasible to isolate some of these proteins from their natural sources or to produce them using bacterial fermentation methods. The purpose of this research was to target recombinant protein expression to the mammary glands of genetically engineered or transgenic animals. Foreign protein expression has been achieved in the mammary glands of rabbits, sheep, cows, and swine. By using a strong mammary gland promoter and signal peptide fused to the protein, it …

The Role Of Ammonia In Reproductive Inefficiency In High-Producing Dairy Cows Fed Excess Rumen Degraded Protein, Douglas Scott Hammon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The role of ammonia in reproductive inefficiency in early lactation dairy cows was studied in a series of experiments designed to determine the concentrations of ammonia in normal bovine follicular fluid (bFF), to determine the effects of ammonia on the bovine embryo during specific stages of development, and to test the hypothesis that elevated plasma urea nitrogen concentration is associated with elevated ammonia and urea nitrogen concentrations in the reproductive fluids.

In the first study, ammonia concentration in different size follicles and the effect of ammonia during in vitro maturation on embryo development were determined. Ammonia concentration in the bFF …

Livestock Watering Practices In The Moroccan Pre-Sahara: Their Effects On Water And Nutrient Metabolism Of Sheep In Different Body Conditions, El Mostafa Darfaoui

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A field survey and a metabolism experiment were conducted to study livestock watering practices in the Moroccan Pre-Sahara and their changes with drought extent, season, ecological zone, pastoral system, and herd size. The metabolism experiment was designed to determine effects of once per 2 days (ID), once daily and twice daily drinking frequencies, and high and low body conditions on water and nutrient utilization by sheep fed high- and low-quality diets.

The way herds are managed in this region exposes all sex and age categories of animals to food and water shortages during annual dry seasons and occasional droughts. Livestock …

Self-Organization Of Foraging Behaviour: From Simplicity To Complexity Without Goals, Frederick D. Provenza, Juan J. Villalba, Carl D. Cheney, Scott J. Werner

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

A herbivore faces challenges while foraging--ongoing changes in its physiological condition along with variation in the nutrient and toxin concentrations of foods, spatially and temporally--that make selecting a nutritious diet a vital affair. Foraging behaviours arise from simple rules that operate across levels of resolution from cells and organs to individuals and their interactions with social and physical environments. At all these levels, behaviour is a function of its consequences: a behaviour operating on the environment to induce changes is itself changed by those events. Thus, behaviour emerges from its own functioningbehaviour self-organizes-not from that of its surroundings. This ostensible …

Management Of Red Squirrel Feeding Damage To Lodgepole Pine By Stand Density Manipulation And Diversionary Food, Thomas P. Sullivan

Vertebrate Pest Conference Proceedings: 18th (1998)

The red squirrel (Tamiasciurus hudsonicus) feeds on the vascular tissues of sapling lodgepole pine (Pinus contorta) during spring periods in forests of interior British Columbia and Alberta, Canada. This damage may lead to mortality and reduced growth of crop trees in managed stands. Manipulation of stand density by pre-commercial thinning to densities < 1,000 stems/ha is an effective method to lower squirrel populations and feeding damage. Lowering stand density enhances the growth of crop trees, and understory herbs and shrubs as wildlife habitat, while protecting trees from squirrel feeding. This approach has been successful in several forest ecological zones. An alternative management tool is provision of diversionary food (sunflower seed) for those stands susceptible to feeding damage, and where stand thinning has already been completed. Diversionary food can be applied aerially and is very cost effective for protecting managed stands. These techniques may be used to maintain or even enhance species diversity of small mammal communities in those forest stands requiring protection.
