Utilisation of fodder from crop residues compensates for non-availability of grasses during the off-season. Unlike the small ruminants that could be left to freely range about all alone, cattle are never left all alone to freely graze about or scavenge, but are conscientiously guided by the rearers in the search for pasture and water; and thereafter, are securely checked into the provided shelter. The NMV method uses exhaust fan ventilation in cold-to-mild conditions with sidewall curtains and wind potential handling warm weather ventilation see Figure 1a. Figure 5. Dissipating this heat to prevent heat stress has become challenging.
Unquestionably, the biggest change in HLPP systems has occurred in the egg-laying sector. Meat constitutes the foremost animal product that is highly explored by the Nigerian households, particularly for direct consumption and as such, the ruminants, especially cattle, constitute the major and cheapest source of meat consumption for most households in the country  about 1million cattle are annually slaughtered for meat in the country. Mastitis and its control, Foot and Mouth Disease. The male herders however return at the start of the wet season to help with crop cultivation and where necessary, household income is supplemented with the sales of surplus male sheep or cattle. But with the relegation of agriculture from the economic fore, use of the number or size of farm animals as measuring tool of social status is no longer tenable, especially at rural level in southwest Nigeria where subsistence agriculture is the main practice. Although, the small ruminants, especially goat, are as well slaughtered for meat sale, the small size of the animals and high market price of their meats makes the animals less demanded for regular meat consumption.
Airborne pollutant concentrations within and emission rates from Australian piggery buildings Thomas Banhazi 9. Specifically, the diseases include rinderpest, foot-and-mouth disease, and contagious bovine pleuropneumonia to be the common diseases of cattle in Nigeria. This movement has been especially prevalent in pig housing systems where the porcine reproductive and respiratory syndrome virus PRRSv has caused significant economic hardship. Socially, the size of the animal is highly intimidating to humans as appearance of unguided cattle in the public is known to cause commotions whereby people run helter-skelter.

They however meet their other basic needs through the proceeds from sales of milk and other dairy products. In addition, the cattle resistant quality to tsetse flies, could as well have been enhanced by Government importation of breeding stock of disease-resistant strain from Gambia in the s; and the tsetse fly eradication and control programme that was put in place during the s and s.
Specific emphasis was placed on general building characteristics, general ventilation design features, heat stress control, and systems designed to address animal welfare. Unlike the devalued state of the socio-cultural value of the small ruminants in southwest Nigeria, cattle, sheep and goats remained relevant as measuring tools of social status and economic strength among the rural households in the northern region of the country.
Utilisation of fodder from crop residues compensates for non-availability of grasses during the off-season. Example ceiling fresh-air diffuser commonly used in HLPP systems.
HVAC design for virus control Disease transmission from herd-to-herd via aerosol transport is a concern, driving significant HLLP system changes to accommodate new and innovative ventilation designs. While about TV systems were first developed in the southeastern quadrant of the USA where the percent calm periods in the summer months can be high.
For this region, the predominant summer winds are from the S-SE and a properly oriented NV building would have the ridge axis E-W or slightly tilted counter-clockwise to expose the sidewall curtains to the predominant summer winds.
General thermal modification systems for housed livestock and poultry In the USA, the raising of food animals in controlled climate facilities has progressed rapidly since the s.
Another important factor determining demand for food is urbanization. Livestock breeding: livestock breeding is crucial to livestock development globally. An increased amount of GHG generates high temperatures on earth. This situation thus accounted for the widespread of sheep and goats among individuals in Nigeria either for consumption, though mostly on events celebration, or rearing for widespread sheep and goats as important animals of trade within humid West Africa though with different demand and consumption patterns in the region.
This system uses higher amounts of labor and resources per unit of land, but it also produces greater yield per unit of land than extensive farming systems.
He has supervised a number of post-graduate students and published a large number of journal articles, conference papers and book chapters, including two textbooks published by the Wageningen Academic Publishers. Phillips Fodder banks are designed not to supply forage year-round for an entire herd but rather to be used strategically for limited periods with selected animals, thus only pregnant and lactating animals are allowed to graze the bank.
This growth is driven by the rapidly increasing demand for livestock products, this demand being driven by population growth, urbanization and increasing incomes in developing countries Delgado • Resource engineer role for intensive animal housing and environment control.
This involved the provision of engineering advice to extension officers and producers, the production of extension material and the coordination of extension efforts on housing, environment control and waste management with pig and poultry extension officers.

The advantages and disadvantages of factory farming often include the ethics of this production method, but there are also some practice reasons why we should continue using this process and why we should avoid it.
