Factors That Affect Reproductive Efficiency in Cattle

The cattle industry is a very important industry in the United States. It is what feeds America and all the other countries in the world. The U.S brings in most of its revenue from agriculture. Without the cattle industry everybody in the world would literally starve. Without the cattle industry we would not be able to obtain beef or milk; two important and common sources of foods that we consume. There are two different breeds of cattle that producers profit from: beef cattle which are raised for meat and veal, and dairy cattle which are raised for milk and other dairy products. Reproduction is an important consideration in the economics of cattle reproduction. A healthy calf each year is normally the usual goal. This is possible by increasing the reproductive efficiency of the cattle. Reproductive efficiency is one main factor that determines if a producer will be profitable or not. Efficiency is important to the profitability of an individual cattle operation and to the competitiveness of the industry as a whole. Reproductive efficiency is a complex phenomenon controlled by both genetic and non-genetic factors. I will be discussing the non-genetic factors that the cattle industry’s reproductive efficiency has declined due to such as feed and nutrition, climate, lactation, and breed of cattle.
Feed and Nutrition Just like any other species what you feed cattle affects the way they work and perform. Nutrition is an important component of a sound reproduction program. A cow’s nutrition and management program can have a profound effect on its herd’s reproductive efficiency. Proper nutritional inputs may afford cattle managers the opportunity to produce cattle more efficiently and become more sustainable. Serious deficiencies or excess of individual nutrients over

Cattle Rearing

...Cattle Rearing Cattles are the most common type of large domesticated ungulates. They are a prominent modern member of the subfamily Bovinae, are the most widespread species of the genus Bos, and are most commonly classified collectively as Bos taurus and Bos indicus. Cattle Rearing is the growing or raising of cattle. Reference http://en.wikipedia.org/wiki/Cattle Breeds and Types of Cattles The two major types of cattle are Bos taurus and Bos indicus. A Bos indicus A Bos taurus Bos indicus cattle have looser, thicker skin, larger ears, a prominent hump, and live in the hotter, humid climates. Bos taurus, on the other hand, lack all of these characteristics (except for the thick hide, which is found in such breeds as the Hereford), and are more adept at living in colder, drier climates. Reference: http://www.answers.com/Q/What_is_the_difference_between_bos_indicus_and_bos_Taurus#ixzz3V23Wx0uH Types of cattle The three basic types of cattle are: * Milk or dairy types - are cattle cows bred for the ability to produce large quantities of milk, by Will Ferguson from which dairy products are made. Dairy cows generally are of the species Bos taurus. Dairy cattle are triangular in shape. * Beef type - are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of adult cattle is known as beef. There are three main stages in beef production: cow-calf operations, back grounding, and feedlot operations. When raised in...

Six groups each composed of nine representative farmers from communal and small-scale conservation enterprises participated in deriving the objective selection criteria of breeding animals using data on economic weights of preferential traits. The shuffled focus groups brainstormed on the mating strategy and management of breeding animals within low-input conservation enterprises. An economic-weight dependent culling method (EWCM) and two-tier open nucleus breeding scheme were conceptualized. The Nguni breeding animals ideally need to maintain optimum body condition score (4 - 6) and low tick counts across seasons under low-input production system. The indigenous breeding bulls need to have high reproductive efficiency while breeding cows must have calved...

Metabolism

...food protein to animal protein? Nutrition and Metabolism of the Cow: Digestive System of the Cow. Proper nutrition is the foundation for a productive and profitable cow herd. Unaccompanied with good nutrition, cattle can’t express their full potential including reproductive efficiency. Cattle are classed as ruminants, they have four compartments to their stomach and chew their cud. The cattle digestive system evolved to be able to handle large volumes of material. Dairy farming is a crucial part to Australia’s rural industry. On farm efficiency is on an increase through the improvement of pasture and feed and also herd management techniques. Supplement the cattle diet with grains and other legumes is becoming increasingly common, the Australia’s dairy industry remains predominantly pasture based. State’s of Australia, Victoria foremost, have attainable milk productions, supplying fresh milk to nearby cities and towns. The industrial value increases through the processing of milk to produce fresh lines such as butter, cream, cheese and yogurt. Bulk milk and specialised powdered milks are also significant. (Crampton, E.W, Harris, L.E (1969) “A Series of Books in Agricultural Science - Animal Science” (W.H Freeman and Company - San Francisco)) Cattle feed can be classed as either roughages (high fibre plants / the fibrous part of the plant) or concentrates (compound feed mix of grain and by products also may have the addition of minerals)(Edwards, R.A, Greenhalgh...

Major Practice in Dairy Production and Milk Processing

...MAJOR PRACTICE IN DAIRY PRODUCTION AND MILK PROCESSING By CHRISTIAN ANDREW J. PERALTA INTRODUCTION Importance of the Major Practice The Philippine local dairy industry is considered as a "repacking and reprocessing" industry because of the limited supply of dairy products due to the less developed dairy industries in the Philippines. It is greatly dependent on imported milk as raw materials, leading to continuous importation from Australia, USA and New Zealand. Philippine’s dairy milk production remains at less than one percent of total dairy requirements despite the continuing government and industry efforts to support and aid the increase of dairy production. Dairy farming goes back for thousands of years and has great difference in management process compare to today’s dairy farming. It was originally done on a mixed farm unlike in modern dairy production in which has specific dairy farm. ________________________ Undergraduate Major Practice Outline in Dairy Production to be presented as partial fulfillment of the requirements for the degree of Bachelor of Science in Agriculture, major in Animal Science from Central Luzon State University, Science City of Muñoz, Nueva Ecija to be conducted in the Philippine Carabao Center, CLSU Dairy Farm under the supervision of Edgar A.

Mineral Supplementation for Cattle and Zinc-Ractopamine Hydrochloride Association to Enhance Animal Performance

...society. Approximately 155 species of ruminants can be found around the globe but only about 6 of them are domesticated, cattle, sheep, goats, buffaloes, reindeer and yaks (Van Soest, 1994). Ruminants are different from all other mammals because of its digestive anatomy composed by four stomach compartments (reticulum, rumen, omasum and abomasum). Another unique characteristic is the interaction between animals, plant and microorganisms present inside the gastrointestinal tract resulting in a symbiotic relationship through gastro-enteric microbial fermentation. Plants consumed by ruminants are utilized as substrates by the microorganisms and the products from fermentation and microorganisms provide energy and protein to the host animal. Animal products such as milk and meat have always been an important component of human diets, therefore technologies to enhance production efficiency and increase economic return for producers are important. Ruminant nutrition research has focused on strategies to improve animal growth performance and carcass quality. Different feed additives and mineral supplementation strategies have been used to influence several characteristics on ruminants and some are used to modify growth. Ractopamine Hydrochloride is one of them, and consists of a metabolic growth modifier used to increase animal performance and has been used in cattle legally since 2003 in the United States of America (Gruber et al., 2007). Therefore, utilization of feed additives including...

...predation relationship between the wildflowers and the kangaroo rats because the kangaroo rats eat wildflowers. Assuming that the fence was limiting the space of the experimental plot, competitive exclusion caused the extinction of the 4 other wild flowers. To begin, there was some interspecific competition, which happens when individuals of different species compete for a resource that limits their survival, between the 5 flower species in the experimental plot because they had their space limited to the fence that they were enclosed in. this competition was a density dependent factor in that the death rate rose when population density in the plot rose. Also, some of the specie’s ecological niches (like what nutrients they needed and how many branches would form) would have had to been the same or else they could coexist together. Then, one of the species of wildflower might have had a reproductive advantage like thorns to repel the kangaroo rats which would have allowed them to prosper and the other species to die out. This is the principle of competitive exclusion. On a tangent, the kangaroo rats would have learned to stay away from the wildflower with thorns by classical conditioning because they paired the idea of getting stung with eating that particular wildflower species and eventually stopped. The control plot, on the other hand, did not have a fence, so they had all the room to grow and didn’t not have to compete for the resources. The reason they didn’t grow even...

The vast majority of studies identified for this review focused on the fate and management of excess nitrogen and phosphorous, their effects on terrestrial and aquatic ecosystems, and contributions to air quality and climate change. Many environmental mitigation efforts were suggested, including balancing nutrient inputs/outputs at the level of the farm, the watershed, and regionally; taking greater care in the timing of fertilizer and manure applications; increased testing for phosphorus and nitrogen in soil; and the use of riparian buffer strips and fencing to protect water bodies. In addition, many studies suggested that cattle stocking rates be calibrated to ensure that nitrogen...

Agriculture

...3% of global land. And per caput availability of resources is about 4 to 6 times less as compared to world average. This will decrease further due to increasing demographic pressure and consequent diversion of the land for non-agricultural uses. Around 51% of India’s geographical area is already under cultivation as compared to 11% of the world average. The present cropping intensity of 136% has registered an increase of only 25% since independence. Further, rain fed dry lands constitute 65% of the total net sown area. There is also an unprecedented degradation of land (107 million ha) and groundwater resource, and also fall in the rate of growth of total factor productivity. This deceleration needs to be arrested and agricultural productivity has to be doubled to meet growing demands of the population by 2050. Efficiency-mediated improvement in productivity is the most viable option to raise production. The country recorded impressive achievements in agriculture during three decades since the onset of green revolution in late sixties. This enabled the country to overcome widespread hunger and starvation; achieve self-sufficiency in food; reduce poverty and bring economic transformation in millions of rural families. The situation, however, started turning adverse for the sector around mid-nineties, with slowdown in growth rate of output, which then...
