Feed resources availability at cheap and affordable prices for livestock consumption are major factors determining capability of livestock production to supply products for increasing urban and cities consumers in Nigeria. To take advantages of the high demand in urban areas, livestock producers on extensive pastoralism are moving closer to cities and urban communities such as Abuja the Nigeria...

The value of dietary exogenous enzymes in promoting growth and efficiency of feed utilization is well recognized in poultry industry. In a case of high-cost yellow corn, several feed producers are choosing to replace yellow corn with other ingredients that have lower nutritional value like triticale, wheat, barley or sorghum. These crops are rich in non-starch polysaccharides (NSPs), and there ...

Ten Holstein steers (141 kg) were used in two 5 X 5 Latin-square experiments conducted simultaneously to determine the effects of offering different levels and types of feeds with endo: phyte-infected rescue given ad libitum. In Exp. 1, steers wer e given ad libitum access to infected fescue hay in the afternoon; in the morning fescue was given ad lihitum (basal) or bermudagrass or clover hays ...

In this experiment the effects of supplementation of the diet of laying hens with sodium selenite (SS) or selenized yeast (SY) on quality of eggs were studied. The chickens of Shaver Starcross hybrid were randomly divided at the day of hatching into 4 groups (n=12 in each group). The birds were fed from Day 1 of life till 9 months of age with diets differing in amounts and/or forms of selenium....

Trace element content of feeds is extremely variable compared to total digestible nutrients or protein. Differences are wide between low and high values for many trace elements within a given type of feed. Coefficients of variation for forages range from 42 to 100%. Summary data are given for both major and trace elements. Problems in supplementation are discussed. Amounts for some elements are...

BACKGROUND Stoned olive pomace (SOP), which represents approximately 50% of the conversion process of olives to olive oil, is largely not utilised and creates costs for its disposal and has negative environmental impacts. In vitro trial experiments were employed to study the effect of feeds integrated with this bio-waste, which is rich in polyphenols, on rumen biohydrogenation, using sheep rume...

The aims of the present study were to investigate the efficacy of measuring bovine urinary zearalenone (ZEN) concentrations by using a commercially available ELISA method in cattle kept under different feeding conditions to monitor the natural contamination of feeds at the farm level, and to investigate the effects of supplementation of a mycotoxin adsorbent (MA) product in the feed based on ur...

Taurine has been demonstrated to be a conditionally indispensable nutrient for several carnivorous fish species. Currently, trout feeds contain reduced levels of fishmeal which had been the primary source of dietary taurine. The reduction of fishmeal in the diet, and thus dietary taurine, may limit growth. A 12-week feeding trial was conducted using a factorial treatment design with taurine sup...

—Taurine has been demonstrated to be conditionally indispensable for several carnivorous fish species. Current trends in trout production include decreasing levels of fish-meal content in feeds, along with faster growing strains of fish. Taurine may be a limiting nutrient in support of elevated planes of growth for rainbow trout. A 9-wk feeding trial was conducted using a factorial treatment de...
