Experiments were conducted to determine the reason for depressed growth in chickens when high levels of bone, bone ash, or calcium were added to diets based on wheat, skim milk, and soybean and/or meat meal, and containing a basal supplement of vitamins and an antibiotic. The growth depression was not due to energy dilution of the diet, nor to an induced deficiency of essential fatty acids or minerals. The growth rates of pair-fed groups of chickens indicated that about half the growth depression was due to a reduced food intake. Depression of appetite and growth was completely prevented by further vitamin . plus antibiotic supplementation of diets containing added bone, bone ash, or calcium carbonate up to a total calcium content of c. 2.5%, but not when calcium exceeded this level. Additions of either vitamins or antibiotics alone produced responses but were not as effective as in combination.

Catfish (Pangasius hypophthalmus) processing industry produces by products of abdoment fat containing unsaturated fatty acids, polyunsaturated fatty acids (PUFAs) which are the essential fatty acids needs to maintain health. Catfish belly fat can be processed into coarse fish oil through a purification process, with the addition of the adsorbent used, one of which is bentonite. This study was aimed to determine the<br />effect of bentonite application on the characteristics of refined catfish oil. Fish oil was extracted from belly fat then purified by adding bentonite adsorbent at a concentration of 1; 4 and 7%. The design used in this<br />study was a complete factorial of one factor. The parameters of analysis were the number of free fatty acids, peroxide value, anisidine, and totox. The results showed that bentonite had significant effect on free fatty<br />acid, peroxide, anisidine and totox values. The use of 7% bentonite decreased content of free fatty acid, peroxide value, anisidine, peroxide and totox from 1.72 to 0.85%, 5.18 to 0 meq/kg, 27.51 to 2.28 meq/kg,<br />and 37.88 to 2.28 meq/kg respectively.

The amplified production of fruit as well as burgeoning demand for plant-made food products have resulted in a sharp increase of waste. Currently, millions of tons of by-products are either being discarded or utilized rather ineffectively. However, these by-products may be processed and further incorporated as functional ingredients in making high-value food products with many physiological and biochemical effects. The chemical analysis of pomace oils using gas chromatography-mass spectrometry (GC/MS) and reversed-phase-liquid chromatography coupled with fluorescence detector (RP-HPLC/FLD) systems led to the identification and quantification of 56 individual lipophilic compounds including unsaturated, polyunsaturated and saturated fatty acids, as well as phytosterols and four homologs of tocopherol. The oils recovered from by-products of Malus spp. (particularly cv. “Ola”) are rich in fatty acids such as linolenic (57.8%), α-linolenic (54.3%), and oleic (25.5%). The concentration of total tocopherols varied among the Malus species and dessert apples investigated, representing the range of 16.8–30.9 mg mL−1. The highest content of total tocopherols was found in M. Bernu prieks, followed by M. cv. “Ola”, and M. × Soulardii pomace oils. A significantly higher amount of δ-tocopherol was established in the oil of M. Bernu prieks, indicating that this species could be utilized as a natural and cheap source of bioactive molecules. β-Sitosterol was the prevalent compound determined in all tested pomace oils with a percentage distribution of 10.3–94.5%. The main triterpene identified in the oils was lupeol, which varied in the range of 0.1–66.3%. A targeted utilization of apple pomace would facilitate management of tons of by-products and benefit the environment and industry.

Tamarind kernels are typically under-emphasized by products of the tamarind pulp industry. The kernel is a fair source of protein, fat (essential fatty acids), carbohydrates and minerals, which can replace conventional flour to develop new food products. The study aims to exploit the under-utilized tamarind kernel for value addition to improve tamarind kernel-based food products’ acceptability and consumption. The tamarind kernel incorporated cookies at 50 percent level of incorporation had moisture of 1.62 %, carbohydrate content of 72.52%, protein of 9.26 %, fat of 22.98%, fiber of 3.25% and ash of 1.12%, respectively. The developed cookies had higher protein and fiber content than control cookies, which depicts its potential to be the better alternative for the conventional flour.

Biomarker Analysis

Throughout evolutionary history, elasmobranchs have developed diverse reproductive strategies. Little focused work, however, has addressed how neonatal nutritional state is affected by differing degrees of maternal investment associated with these markedly different reproductive strategies. To investigate the effect of maternal investment on the nutritional quality of pups during the early life history of an extremely viviparous elasmobranch, quantitative biomarker analysis including lipids, fatty acids and stable isotopes was conducted. Using the cownose ray Rhinoptera bonasus (histotrophic viviparous) as a model, we found that pups were initially born in a positive nutritional state, enriched in physiologically important essential fatty acids and nitrogen and carbon stable isotope values (δ15N and δ13C), a result of maternal intrauterine transfer. A systematic decrease in some fatty acids and δ15N values, as well as a decrease in cholesterol with growth, confirmed that these substrates were derived from maternal resources and used in initial metabolic processes following birth. An observed increase in condition factor, plasma essential fatty acids and triglyceride:cholesterol ratio with increasing body size identified a progression towards successful independent foraging with pups not displaying marked nutritional deficiency or fasting phases. Our multi-tracer approach allowed the identification of 2 size classes of young rays (<50 and <70 cm disc width) that displayed distinct physiological states. Since prenatal maternal investment is critical for offspring condition and to promote successful foraging post birth, understanding the trophic ecology and physiological state of pups during their first year is critical to guide management and conservation within nursery grounds.
