A total of 400 broilers were randomly divided into five groups, each of which received a different treatment. The first group was considered a negative control and did not experience any HS (C^-); the second group was considered a positive control (C⁺) and was exposed to HS; the third group received only vitamin C (250 …

Differential Impacts Of Cereal And Protein Sources Fed To Pigs After Weaning On Diarrhoea And Faecal Shedding Of Escherichia Coli, Production, And Total Tract Apparent Digestibility, John R. Pluske, Bruce P. Mullan, Jae Cheol Kim, David J. Hampson

Animal production and livestock research articles

Different cereal types, in combination with different protein sources, are fed to pigs after weaning, but their interactions and possible implications are not well researched. In this study, 84 male weaned piglets were used in a 21-day feeding trial to investigate the effects of feeding either medium-grain or long-grain extruded rice or wheat, in a factorial combination with protein sources of either vegetable or animal origin, on postweaning performance, shedding of β–haemolytic Escherichia coli, and the coefficient of total tract apparent digestibility (CTTAD). Pigs fed either rice type performed the same (p > 0.05) as wheat-fed pigs after weaning. The use …

Buying Healthy Goats And Keeping Them That Way, Susan Kerr

Professional Agricultural Workers Journal

Abstract

Starting a goat herd with healthy animals prevents expense and effort eliminating infectious diseases. Pre-purchase testing and examinations are worth their cost because of the savings realized through fewer animal illnesses, increased production, lower medication costs, and reduced culling. Key management practices such as hoof trimming, vaccinating, body condition scoring, and assessing parasite loads are needed to maintain herd health. Biosecurity practices must become routine to prevent the introduction and/or spread of contagious diseases. Several goat diseases are contagious to humans, so biosecurity measures must address this concern. Excellent record-keeping helps producers monitor health and production trends, document treatments, …

Grazing System And Management For Goat Production, Steve Hart

Professional Agricultural Workers Journal

Abstract Grazing system management is for supplying inexpensive, adequate nutrition for the goat enterprise. This involves managing forages to facilitate dry matter production and managing grazing so forage quality is adequate and harvest efficiency is high while avoiding consuming internal parasites. Since nutrient costs are greatest for winter, the grazing system should be planned to provide some grazing during winter. The forage system should be managed to provide the greatest proportion of nutrients possible during kidding and lactation. The base forage species can be overseeded with cool-season or leguminous species to improve forage production, quality or the seasonal distribution of …

Year-Round Forage Production For Sustainable Goat Farming, Uma Karki

Professional Agricultural Workers Journal

Abstract

Goat farming in the U.S. is based on grazing lands. Forages available for grazing throughout most of the year are essential for supplying required nutrition for goats and minimizing production costs. Most goat farmers do not have pastures productive for an extended period. This situation results in poor performing animals and high production costs. Forage availability can improve by enhancing the productivity, quality, and production duration of pastures. The inclusion of browse species in grazing systems will also improve diet variety, minimize internal parasite problems, and better utilize the soil resources. Grazing opportunity can be extended by developing a …

Comparison Of Productivity Of Different Breeds Of Meat Goats Under Low-To-Moderate-Input Systems In The United States, Richard Browning Jr., Maria L. Leite-Browning

Professional Agricultural Workers Journal

Abstract

Boer and Kiko goats were imported in the 1990s to enhance the productivity of the US base population of Spanish meat goats. Successful breed introductions require adaptation to the destination environment. Well-planned, low-input management is a good route to meat goat enterprise profitability using proper goat genetics. Reproduction drives profit more than growth and carcass traits. Results of breed evaluation studies on doe reproductive and health traits, the Boer goat influence tended to be negative compared with Kiko and Spanish goat influences. Reduced doe herd reproductive output suggests reduced enterprise profitability. Differences in growth or carcass traits among sire …

Marketing Toward The Future, Niki Whitley, Susan Schoenian

Professional Agricultural Workers Journal

Abstract

United States goat producers face many challenges with regards to marketing. Although the demand for goat products is increasing, the market is fractured. There is a general lack of infrastructure and many producers do not sell their animals or products for fair or profitable prices. Production costs are too high, and there is a need to improve production efficiency. Imports pose a challenge to US goat producers, as domestic production cannot compete with the availability and lower cost of imports. Government regulations hinder market development because non-commercial slaughter is an important aspect of goat marketing, and regulations keep many …

Nutritional Requirements Of Different Classes Of Meat Goats, Nar Gurung

Professional Agricultural Workers Journal

Abstract

Feeds provide nutrients to animals. Feeds can be grains, crop by-products or forages. Forages can form the basis of feeds for goats in the southeastern US because year-round forage production is possible. Since goats are classified as browsers, the forage program should consist of browse and pasture. Managing browse species as feed resources is challenging, and there is limited information relative to managing browse species. Hay is the main forage feed for goats in the region and average quality hay can meet nutrient requirements for maintenance. However, nutrient requirements for late-pregnancy, lactation, and growing goats cannot be met with …

Best Management Practices For Internal Parasite Control In Small Ruminants, Susan Schoenian, Enrique Nelson

Professional Agricultural Workers Journal

Abstract

Internal parasites represent a significant obstacle to a profitable and sustainable US goat industry. In some states, internal parasites are a year-round problem, while in others, they are a more seasonal challenge. Traditionally, parasite control methods relied heavily on antiparasitic drugs called anthelmintics or dewormers. Continued use and misuse of these drugs have resulted in increasingly resistant worm populations, necessitating more holistic or integrated methods of parasite control. A combination of practices will usually be necessary to achieve a satisfactory level of control. This paper discusses best management practices for controlling internal parasites in small ruminants, including pasture and …

Reproductive Technologies Used To Make Goats More Efficient, Seyedmehdi Mobini

Professional Agricultural Workers Journal

Abstract

With the introduction of Boer and Kiko breeds for meat goat production in the United States, more emphasis is being placed on the reproductive management to increase the number of offspring born and weaned and the frequency with which they are produced. It is also desirable to produce out of season kids to take advantage of a market premium for milk and meat. Reproductive manipulations, commercial Artificial Insemination (AI) programs using fresh or frozen semen, and Embryo Transfer (ET) have been developed and are in use most commonly in goats for reproductive efficiency.

Goat Mortality Composting, Roger Merkel

Professional Agricultural Workers Journal

One lawful method to dispose of animal carcasses is composting. Mortality composting is a “green” method that provides the producer with valuable soil amendments. Composting sites should be away from water sources and public areas. Some states require a facility and/or permit for carcass composting so producers should contact their State Veterinarian. Animal composting generates little to no odor and generates temperatures high enough to kill pathogens. Mortality composting is an aerobic process and requires a proper C:N ratio achieved by using a high carbon source to envelop the carcass, moisture content of roughly 50%, and available oxygen. Common composting …

Optimizing Reproductive Performance In The Goat Herd, Dahlia O'Brien, Stephen Wildeus

Professional Agricultural Workers Journal

Abstract

Reproductive efficiency impacts pregnancy rates, kidding/lambing frequency and number of offspring available for market each year. To enhance reproductive performance, consider breed, selection, nutrition and health, and understand basic female and male reproduction. Proper ration formulation and feeding promotes reproductive function and leads to more offspring. Selecting the highest performing females while culling unproductive does increases reproductive rates. Diseases affect the reproduction and survival of kids, so adopting disease prevention strategies including routine vaccinations and deworming protocols that promote good herd health is necessary. Understanding male and female reproduction are critical in managing puberty, minimizing the effects of seasonality …

This LCA is …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Polymorphisms Of Bovine Hsp90 And Their Implications In Beef Cattle Productivity, Glynn G. Smith

Animal Science Undergraduate Honors Theses

Production of beef cattle represents a $60 billion industry in the United States (USDA, 2015). The American beef cattle industry loses an estimated $370 million annually due to heat stress (St-Pierre, 2003). As of 2003, this was equal to nearly 99 million pounds of beef lost (USDA, 2015). The average American consumed roughly 65 pounds of beef in 2003; this means that the 99 million pounds of beef lost to heat stress would have been enough to feed approximately 1.5 million Americans for an entire year (Barclay, 2012).

Sheep Worms – Breeding Worm Resistant Sheep, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Lost productivity due to drench resistance in sheep worms has been recognised as a widespread problem in Western Australia (WA) since the 1980s. The first member of the macrocyclic lactone (ML) group, ivermectin, was released in Australia in 1988 and by 1993 the first case of resistance to this group was discovered. It is now thought that more than 85% of WA sheep farms are likely to have ML resistant sheep worms. In other parts of Australia, resistance to barber's pole worms is especially severe and involves all drench groups except the newly-released drench, monepantel (Zolvix).

The Effect Of Lupinus Albus On Growth Performance, Body Composition And Satiety Hormones Of Male Pigs Immunized Against Gonadotrophin Releasing Factor, Karen Moore, Bruce Mullan, Jae Cheol Kim, Frank R. Dunshea

Animal production and livestock research articles

Two hundred and ninety four pigs were used with the aim to develop a dietary management strategy using Lupinus albus L. (albus lupins) to reduce the increase in feed intake and subsequent increase in carcass fatness in pigs immunized against gonadotrophin releasing factor (immunocastrates; IC males) and entire male pigs in the late finishing stage. From day (d) 0 to 28, IC males fed the control diet grew faster (p = 0.009) than entire males fed the control diet but there was no difference in growth rate between sexes for pigs fed albus lupins for 14 days pre-slaughter (Albus 14) …

Genetic Polymorphisms Of The Glucocorticoid Receptor And Interleulin-8 Receptor Genes And Their Relationship To Production Traits And Hair Coat Scores In Crossbred Cattle, Avery B. Deaton, Laura Meyer, Jeremy Powell, Charles F. Rosenkrans Jr.

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Little is understood about how the diversity of genes, specifically the glucocorticoid receptor (GR) and interleukin-8 receptor (CXCR2), are related to reproductive health and how this affects physical traits in cattle. Glucocorticoid receptors have been positively associated with higher milk yields, lactose content, feed intake, and feed conversion rates. Interleukin-8 genes are part of the innate immune response and help with many aspects of female reproductive health, such as protecting the embryo from the maternal immune system during pregnancy. The objective of this research was to identify polymorphisms in the GR and CXCR2 genes and to associate genotypes between the …

Cost-Benefit Analysis Of A Genetic Marker On Cow-Calf Operations Differentiated By Pasture And Breed, Josh C. Crystal, Michael P. Popp, Nathan P. Kemper, Charles F. Rosenkrans Jr.

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Genetic sequencing in beef cattle (Bos taurus L.) is expected to aid producers with selecting breeding stock. Using data from experimental trials conducted with Angus, Brahman, and their reciprocal cross, the single nucleotide polymorphism (SNP) P450 C994G marker expression was investigated for use in selecting genetics suited to grazing endophyte-infected tall fescue (Festuca arundinacea Schreb. L.) compared to bermudagrass (Cynodon dactylon L.) pasture. The study is unique in the sense that actual cow-calf breeding failure rates (open cows were not culled) were tracked from 1991 to 1997 on herds that were bred to calf in spring and were either exposed …

The Effect Of Lupinus Albus And Calcium Chloride On Growth Performance, Body Composition, Plasma Biochemistry And Meat Quality Of Male Pigs Immunized Against Gonadotrophin Releasing Factor, Karen Moore, Bruce P. Mullan, Jae Cheol Kim, Frank R. Dunshea

Animal production and livestock research articles

Two hundred and ninety-four pigs were used to assess the effect of two ingredients (Lupinus albus (albus lupins) or a combination of calcium chloride and sodium tri-polyphosphate (mineral salts)) on growth performance, body composition and objective meat quality of pigs immunized against gonadotrophin releasing factor (immunocastrates) and entire male pigs in the late finishing phase. Pigs fed mineral salts ate less feed than those fed the control diet with no effect on growth rate (p > 0.05), backfat (p > 0.05) or fat deposition (p > 0.05). Pigs fed albus lupins had a reduced feed intake (p < 0.001 for all time periods), lower growth rate (p < 0.001 for all time periods), lower backfat (p < 0.005) and decreased fat deposition (p < 0.001 for all time periods) compared to those fed the control diet or mineral salts. From day (d) 0–28 pigs fed mineral salts had a better feed conversion ratio (p = 0.001) than those fed albus lupins who in turn had an improved feed conversion compared to the control diet. Immunocastrates had thicker backfat than entire males at the end of the experiment (p < 0.001), however, feeding albus lupins to immunocastrated males reduced backfat thickness to similar to entire males fed the control diet (p = 0.01). With the exception of the increased muscle pH at 45 min post-exsanguination in mineral salts and albus lupins compared with the control diet (p = 0.03) there was no effect of diet on objective pork quality. Pork from IC males had a higher ultimate pH (p < 0.001), was lighter (L*; p = 0.003), more yellow (p = 0.008) and had a higher drip loss (p < 0.001) compared to entire males. Albus lupins show potential in reducing the increase in feed intake and backfat associated with immunocastration. Mineral salts may be useful in situations where a reduction in feed intake and an improvement in feed conversion is desired and reducing fat deposition is not the objective.

Acetylsalicylic Acid Supplementation Improves Protein Utilization Efficiency While Vitamin E Supplementation Reduces Markers Of The Inflammatory Response In Weaned Pigs Challenged With Enterotoxigenic E. Coli, Jae Cheol Kim, Bruce P. Mullan, John L. Black, Robert J E Hewitt, Robert J. Van Barneveld, John R. Pluske

Animal production and livestock research articles

Background

This experiment was conducted to test the hypothesis that vitamin E (Vit E) and acetylsalicylic acid (ASA), a cyclooxygenase-2 (COX-2) inhibitor, will additively reduce the production of the immunosuppressive molecule prostaglandin E2 (PGE2) and hence reduce inflammatory responses in weaner pigs experimentally infected with an enterotoxigenic strain of E. coli.

Methods

The experiment was conducted in a research facility with 192 individually-housed male weaner pigs (Landrace × Large White) weighing 6.6 ± 0.04 kg (mean ± SEM). The pigs were experimentally infected with an enterotoxigenic strain of E. coli and were allocated to a 2 × 3 factorial …
