The objective of this project was to investigate the effects of selecting sires for residual feed intake (RFI) on the performance of their daughters. Bulls with low or high estimated breeding values (EBV) for RFI were selected from the Angus Society of Australia sire summary and mated to Angus cross commercial cows at the Kansas State University Cow-Calf Unit in 2005 and 2006. The average EBV o...

Iran contributes to the stock enhancement of several economically valuable fish species, including the Caspian salmon, S. trutta caspius, by producing and releasing millions of fingerlings into the sea. This work was conducted to determine the production costs of the Caspian salmon fingerlings in the years 2002 and 2003. For this purpose, a questionnaire was prepared and filled in by an expert ...

The major sources of variability in net farm income on New York dairy farms over the past 10 years are identified using Dairy Farm Business Summary records. The most important source of income variability is the fluctuation in milk prices, followed closely by year-to-year variation in the quantity of purchased feeds. These results suggest that forward pricing of milk and feed purchases may be e...

Fifty-six acres of central Iowa corn land were seeded to bromegrass and divided with high-tensile wire into eight seven-acre plots. This bromegrass was fertilized with 70 pounds of nitrogen each spring and fall, 1987-1990. In 1991 – 1995, the nitrogen was increased to 80 pounds both spring and fall. The plots were stocked with 1.3 cow/calf pairs per acre in 1987-1991 and 1993–1995, but in 1992 ...

With Increasing Energy Demand in the World and to keep Environment Friendly, biogas technology has attained a notable position for the future scope. This paper tells about a comprehension review on anaerobic digestion of cow dung and food waste with Water hyacinths to enhance biogas productions. Water hyacinths are treated as waste in rivers, ponds, but they have high potential in biogas produc...

The growth of 94 normal term infants was studied from birth to 6 months. 33 infants were breast fed and the others randomly allocated to one of 3 bottle feeds--Cow and Gate V formula, Baby Milk Plus, and Premium. The weight, length, and head growth velocities were similar in all 4 groups. The infants fed Cow and Gate V formula consumed a larger volume of feed at 3 months than the infants fed th...

In dairy farms, the feeding cost, which includes expenses for purchased feed but also production, constitutes a very large part of production cost (more than 60%), indicates economic importance strategy. This study discerns three different strategies: landless farms only purchasing from markets (“Purchasing”), home-grown feeds stand more 10% costs (“Producing”) and with less (“Multi-purpose”). ...

The indirect effects of mastitis treatment are often overlooked in cost-benefit analyses, but it may be beneficial for the dairy industry to consider them. The cost of mastitis treatment may increase when the duration of intra-mammary infections are prolonged due to misdiagnosis of host-adapted mastitis. Laboratory diagnosis of mastitis can be costly and time consuming, therefore cow-side tests...

Densification of the feeds could be a solution to feedstock deficiency for biogas plants and ultimate option for waste management. This paper deals with development of a environmentally and farmer’s friendly technology for sustainable use of waste,through densification and development of a package of integration of nutrients, alternate waste and binder etc with cow dung for biogas plant. The la...
