Opinions vary regarding how much distiller’s grains (DG) can be used effectively in lactation rations. In order to better understand conflicting reports and recommendations about the effect of DG on milk yield we examined 23 studies about DG in the dairy science literature. Inclusion of DG in treatment diets ranged from 4 to 42% of dietary DM across all studies. Our analysis of the entire datab...

Increased cost of common feedstuffs and increased availability of coproducts from plant-based biofuel manufacturing has enhanced interest in the use of these coproducts in rations for dairy cattle (Donkin and Doane, 2007). Glycerol (commonly marketed as crude glycerine with a glycerol content of approximately 80%) is a coproduct produced during biodiesel production from soybean oil and is becom...

Protein available to ruminants is supplied by both microbial and dietary sources. Metabolizable protein (MP) is the true protein which is absorbed by the intestine and supplied by both microbial protein and protein which escapes degradation in the rumen; the protein which is available to the animal for maintenance, growth, fetal growth during gestation, and milk production. Thus, the concept of...

A study was conducted to determine the effects of water temperature and rations size on growth performance, feed utilization and carcass biochemical composition of juvenile Benni. Six treatments representing a combination of two water temperature (24 and 28 °C) and three feeding rations (1%, 3% and 5%) were tested with three replicates. Each replicate was stocked with 12 fish (30.66±0.81 g aver...

BACKGROUND The problem of low female literacy rates in Africa starts with low primary school enrollment, particularly in areas of high food insecurity. The provision of food in, and through, schools is considered to be one way of enrolling more girls in school, keeping them enrolled, and enhancing their adult well-being and productivity as a result. OBJECTIVE To investigate the effects of pro...

Three experiments were conducted with Ross-type broiler chicks to determine the optimum level of in­clusion fish meal and value bloodmeal as a substitute for fishmeal in practical starter ra­tions. The was found In be 7.5%. Higher levels tended increase cost production lower growth performances. ad­dition all vegetable protein rations resulted better performances than ration. II that blood coul...

Fif teen lactating Holstein cows in a 3 × 3 Latin square experiment determined effects of ground newspaper in the diet. Test components of the rations were: A) 20% cottonseed hulls; B) 10% paper and 10% cottonseed hulls; C) 20% paper. All animals received 2.3 kg of long alfalfa hay daily. Proximate analysis and gross energy determinations indicated that the paper rations contained more crude fi...
