C ORN silage is being utilized in increased quantities in beef cattle growing and fattening rations. The research data of Hammes et al. (1964), with various ratios of corn to corn silage in fattening rations, have demonstrated that higher levels of corn silage can be justified because gains between high grain and high silage rations are similar, whereas, use of higher silage rations permits the...

The aim of the work was estimation of copper intake with the daily food rations used for alimentation of students of military high schools and soldiers doing compulsory military service in the Polish Army. An average planned copper content in daily food rations used for alimentation of students and soldiers amounted to 2.49±0.35 mg, and 2.44±0.25 mg respectively. The copper content in the daily...

An in vitro study was conducted to evaluate the optimum roughage to concentrate ratio in complete rations using unconventional sweet sorghum bagasse (SSB), a by product of ethanol industry as sole roughage source. Eight rations were prepared with roughage to concentrate ratio of 100:0 to 30:70. Significantly (P<0.01) higher in vitro gas production volume (ml) at 24 h incubation, in vitro organi...

The aim of the present study was to evaluate the vitamin and mineral content of bone and raw food rations fed to adult dogs in Germany. Pet owners completed a standardised feeding questionnaire. The composition of 95 rations was calculated from mean data for foodstuffs using nutrition balancing software. Typical ration ingredients were meats, fish, offal, dairy products, eggs, oil, nuts, cod li...

Food technology has been instrumental in ensuring that troops remain “fit to fight”. Early food technologies produced flat bread, hard biscuits, cheese and salted meat, allowing Roman legionaries to carry rations for several days. Canning was invented in the late 18th century in response to the French Government’s offer of a substantial reward to the person whose invention would allow troops to...

A twoto four-fold increase in corn prices in recent years over historical trends has prompted many questions about alternatives to corn for dairy rations. As corn is a low protein high energy feedstuff, its continued use even with high prices or concern over its partial replacement is mainly confined to rations for lactating cows where meeting the energy requirements of milk production is impor...

Phenotypic flexibility is critical in determining fitness. As conditions change during ontogeny, continued responsiveness is necessary to meet the demands of the environment. Studies have shown that subsequent ontogenetic periods of development can interact with one another and shape developmental outcomes. The role genetic variation within populations plays in shaping these outcomes remains un...

This study aimed to compare local dairy farmer ration formula with national research council in producing higher feed efficiency and milk production. This study had two stages. The first stage was in vitro study of dairy farmer rations which have different raw materials (R3, R4, and R5) with NRC based ration (R2) and Demo Farm ration (R1). The variables measured in this stage were proximate com...

1. Statistical analyses were carried out on results obtained under strictly-controlled conditions in metabolism stalls with forty-one different rations fed to 127 adult non-pregnant dry cows, and with fourteen other different rations fed to thirty-five adult non-pregnant lactating cows that had calved 2-6 months earlier and whose daily milk production ranged from 11 to 20 kg. 2. Correlations be...

Introduction Ionophores have been used extensively in the beef industry in Canada since 1977. Until recently, there has been no label indication for use of ionophores in lactating dairy cattle. Ionophores are feed additives that alter rumen microbial populations through ion transfer across cell membranes. In Canada, the label warning prohibiting the use of Rumensin premix in lactating dairy ca...
