Growth Performance and Feed Conversion Efficiency of Crossbred Heifers
Theexperiment was conducted to investigate the growth performance and feed conversion efficiency of crossbred heifer at different age level in Government Dairy Farm in Bogra, Bangladesh. Twelve female crossbred heifers were equally distributed (n=3) into four groups [Group A: (7±2 months), B: (12±2 months), C: (15±2 months) and D: (20±2 months)] according to age and fed concentrate mix, rice st...
متن کاملEcological pricing and economic efficiency
There is a need to accurately account for the contributions of environmental assets to the overall economy. Such accounting would permit policies that allow protection of important natural resources and aid the analytic process to determine an accurate basis for a sustainable economy. The aim is to develop an accounting framework for ecology that is sufficiently consistent with the economic fra...
متن کاملCharacterization of Shrimp Farm Effluents in Honduras and Chemical Budget of Selected Nutrients
The percentage of world shrimp production in Central America is only about 7% (Rosenberry, 1994), but the industry is important to local economies. In Honduras, over $70 million was generated by shrimp culture in 1994 placing the industry third in national export earnings. Sustainability of the industry is economically critical, and could depend on estuarine water quality. A 2-yr baseline of wa...
متن کاملEffect of Wet Feeding on Feed Conversion Efficiency in Laying Hens during Summer Season
The aim of this study was to investigate the effect of wet feeding on feed conversion efficiency in laying hens during summer season. The study was carried out on 192 pullets of eight weeks age (distributed to four groups). The feed offered to chicks consisted of starter diet up to 8 weeks of age and grower diet up to 20 weeks of age. From 20 weeks onwards, birds were provided with layer diet u...
متن کاملFeed-conversion ratio of finisher pigs in the USA.
Although the feed-conversion ratio is recognized as a prominent indicator of profitability for pork producers, only 212 (50.7%) of 418 producers who were asked the feed-conversion ratio for finisher pigs provided a response during the USA National Animal Health Monitoring System 1995 National Swine Study. Of these, 126 (59.4%) producers furnished a feed-conversion ratio which they characterized...
