Even though extensive research has examined the role of nutrition on milk fat composition, there is less information on the impact of forages on milk fatty acid (FA) composition. In the current study, the effect of replacing grass silage (GS) with maize silage (MS) as part of a total mixed ration on animal performance and milk FA composition was examined using eight multiparous mid-lactation co...

A research for eight weekswas conducted to evaluate the effect of substituting fish meal with local agricultural products in diet Nile Tilapia (Oreochromis niloticus).Three treatment dietaries were prepared. The dietary composition tested diets is as follows: A1/plant based-diet (Groundnut cake, sesame millet bran, maize and 0% meal) A2/fishmeal partial replacement meal, 10% A3/fishmeal 25% mea...

Differences in the nutritive value of four grades of stackburned yenow maize, obtained from a single storage unit in Mozambique, were examined. Samples were analysed for chemical composition, and subjected to the fonowing in vitro assays for estimating digestibility: total dietary fibre and pancreatin for non-ruminants, and gas production using sheep rumen fluid for ruminant livestock. Samples ...

This experiment aimed to quantify the methane emissions and intake, digestibility, performance, and carcass characteristics of finishing beef cattle offered maize (Zea mays) silages harvested at 1 of 4 sequential stages of maturity and to relate these values to those obtained from animals offered an ad libitum concentrate-based diet. Sixty continental crossbred steers with a mean initial BW of ...

In total, 20 multiparous Holstein-Friesian dairy cows received one of four diets in each of four periods of 28-day duration in a Latin square design to test the hypothesis that the inclusion of lucerne in the ration of high-yielding dairy cows would improve animal performance and milk fatty acid (FA) composition. All dietary treatments contained 0.55 : 0.45 forage to concentrates (dry matter (D...

Two groups of Merino sheep (with or without rumen fistulae) were used to study the effect of feeding maize-silage (compared to hay) on: thiamine concentrations in rumen fluid, tissues and organ; blood transketolase activity; microbial fermentation in the rumen. After sheep were transferred from a hay diet to maize-silage, thiamine concentrations in ruminal fluid fell to about 25% of control val...

To determine values for the digestible indispensable amino acid score (DIAAS), it is recommended that ileal amino acid (AA) digestibility values obtained in growing pigs are used to characterise protein quality in different foods. Therefore, an experiment was conducted to determine the standardised ileal digestibility (SID) of AA in eight cereal grains (yellow dent maize, Nutridense maize, dehu...

In this study, fish meal (FM) was replaced by the black soldier fly maggot meal (BSFM) with replacement levels at 0%, 25%, 50%, 75% and 100%. The feeding trial was conducted for 56 days and the effect of each replacement level on the growth performance, feed utilization, body composition and survival of the experimental fish was assessed. All the experimental diets were well accepted by the fis...

canistel (pouteria campechiana) is an underutilized fruit tree species found in many parts of the world. the objective of this study was to evaluate suitability of canistel fruit meal (cfm) as a feed ingredient for broiler chickens. giving completely randomize design, ninety broiler chickens in 30 floor pens received one of five diets ad libitum from day 21 to 42. the nutritionally balanced con...
