The proximate chemical composition, mineral, fatty acid, and amino acid profiles of Nigella seed meal (NSM) was determined. In addition, apparent (AAAU) and true (TAAU) amino acid utilization, and apparent (AMET) and true (TMET) metabolisability were determined using a force-feeding…
Incorporating olive pomace (OP) into ruminant feed can alleviate the environmental impact of OP disposal, minimize food–feed competition, and bolster food security. However, high fibre and low crude protein (CP) reduce its nutritional value for ruminants. The study assessed the…
The objective of this study was to determine the effect of a mixture of essential oils (EO), calcium malate (CM), or their combination (EO + CM) on the physico-chemical characteristics of lamb meat. A total of 36, two-month-old, 20 ±…
Agroecological dairy production systems are gaining attention worldwide. However, few studies have compared the quality of bovine milk produced in these systems with that produced in conventional dairy production systems. In view of the different farming practices, it was expected…
Tiger nut (Cyperus esculentus L.), or chufa, is a plant that is found in nature and is cultivated for its edible tubers. The purpose of this study was to determine the chemical composition, nutritive value, and in vitro digestibility of…
The objective of this study was to evaluate the nutritional characteristics of meat from lambs fed diets containing 0%, 12.5% and 25.0% (dry matter (DM)) mulberry hay as a substitute for the concentrate. Twenty-four feedlot Île-de-France lambs with an average…
The aim of the study was to evaluate the nutritional status of scavenging chickens by assessing the composition of their crop contents. The study was conducted on 288 free-ranging indigenous chickens from six adjacent rural villages in Venda region of…
The objective of the work was to evaluate the influence of genetic and mechanical removal of hulls from oat grains on their nutrient content. The studies included three cultivars and six lines of oat grains. In grain samples of hulled…
This study was carried out to investigate the effect of conventional farming systems for laying hens (standard cage batteries) and new alternative systems (improved cages and free range), approved by European Union (EU) poultry welfare legislation, on the chemical and…
The aim of this work was to evaluate the nutritive value of carob pulp for rabbits using the in vitro digestibility and gas production techniques with inocula from caecal content of rabbits. Experimental diets contained 0% (D1), 10% (D2), 20%…
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…
The objective was to determine the effects of wilting, molasses and inoculants on the biochemistry and in vitro and in situ digestion of lucerne silage. Lucerne containing 200 g/kg of dry matter (DM) was ensiled as fresh or wilted (370…
The study compared the nutrient content of selected joints of South African mutton (Class C2) (n = 18) and lamb (Class A2) (n = 18) carcasses of fat code 2 in both classes. South African sheep carcasses are classified according…
A randomized complete block design with five replications was used to assess biomass yield, in vitro dry matter digestibility (IVDMD) and nutritional value of spineless cactus (Opuntia ficus-indica) produced under drip irrigation and fertilization. Cladodes were harvested from an established…
Digestion trials using sheep and voluntary feed intake (VFI) trials using long yearling heifers in Calan gates were conducted in the spring, summer and autumn over 5 years. These data and the chemical composition of the herbage were regressed on…
The study was conducted firstly to establish the influence of cultivar and environment on the protein-, amino acid and ether extractable oil concentration of sunflower seed and secondly to study the influence of soil pH and fertilization on the protein…
Nutrition research with grazing ruminants. Native pasture is still the main source of feed supply for the sheep and beef cattle industries. Apparently an inadequate intake of digestible nutrients puts a limitation on animal production. Due to the seasonal pattern…
Rice-straw was ensiled with a 5-6% urea solution for 3 weeks before being fed. Cattle fed with urea-ensiled rice straw alone can maintain weight. However, to obtain a daily weight gain of 300-450 g in Holstein Friesian heifers (8-12 months…
Food preferences and food selection by giraffe have been extensively investigated but little data concerning the chemical composition of the preferred species are available. The aim of the present study was to determine whether the differences and seasonal changes in…
Various studies on the food preferences of giraffe indicate that the leaves of the Acacia and Combretum species are the most important food items selected. The present study was aimed at comparing the chemical composition of the leaves and explaining…
