Results of experiments carried out on the tilapiine fish Oreochromis aureus (Steindachner) to evaluate the method used in the determination of the apparent dry matter and nutrient digestibilities of an ingredient, together with validity of estimations based on day and night collection of faeces, and internal and external markers, are presented. The apparent dry matter and protein digestibilitie...

Growth trial of thirteen weeks’ duration was carried out on 24 pigs (2 months age; 12.5 kg b. wt.) which were divided into four groups of 6 pigs each and were fed with control diet concentrated feed mixture (CFM) (T0), CFM plus polyherbal superliv (500 g/ton) (T1), CFM plus polyherbal Ruchamax (500g/ton) (T2) and CFM plus AV/AGP/10 polyherbal (500g/ton) (T3). The dry mater intake (DMI) (g/d) in...

The wet chemical analysis of feed samples is time consuming and expensive. Near infrared spectroscopy (NIRS) was developed as a rapid technique to predict the chemical composition of feeds. The prediction of accuracy of NIRS relies heavily on obtaining a calibration set which represents the variation in the main population, accurate laboratory analyses and the application of the best mathematic...

Forty-eight crossbred weaner pigs divided into three groups of sixteen pigs each were used to assess the effect of feeding frequency on the performance and nutrient digestibility. The same type and quantity of feed was rationed once, twice and thrice daily. Performance of pigs fed twice daily was better than those fed once per day. Digestibility of dry matter, crude protein and crude fibre incr...

to determine the amount of food amino acid and to spend time in the laboratories are expensive & time-consuming due to a chemical analysis. in the current laboratories, digestion nirs method is widely used for this purpose. but this method has technical limitation. therefor is important find appropriate method for estimate amount of amino acids. artificial neural network (ann) can provide a bet...

Aim: The present study was carried out to evaluate the nutrient digestibility of sweet sorghum stover, an unconventional roughage source in ram lambs in comparison to conventional sorghum and maize stovers. Materials and Methods: 18 Nellore ram lambs aged about 3 months (average body weight 15.65±0.10 kg) were randomly allotted to three complete rations formulated with roughage to concentrate r...

BIEL, W. and E. JACYNO, 2013. Chemical composition and nutritive value of spring hulled barley varieties. Bulg. J. Agric. Sci., 19: 721-727 The objective of this research was to evaluate the chemical composition and nutritive value of four spring hulled barley varieties (Antek, Skarb, Nagradowicki and Granal) grown in one location in Poland. In the study were determined: chemical composition, a...

Changes in the chemical composition and functional properties of fermented seed flour of Pigeon pea, Cajanus cajan L. were studied for 0,1,2,3,4 and 5 days. The differently fermented seeds were analyzed for proximate composition, calorific values and functional properties. Results showed that fermentation significantly (p≤ 0.05) increased the moisture, protein and ash contents of the seed while...

In the Molise region (Italy), some autochthonous populations are still bred and, between them, some wild horses named 'Pentro horses.' The breeding area is a natural pasture. It is 2200 ha extended including a broad plane surrounded by wooden hills. The aim of this research was to determine the nutritional characteristics of this area over a 2-year period to improve the management of the herd a...
