Two experiments were carried out to evaluate the inclusion of vegetable oils with different fatty acid content in starter and pre-starter broiler diets. In Experiment I 480 1- to 9-day-old male Ross 308 broilers were fed diets containing corn oil (CO), acid corn oil (ACO), linseed oil (LO) or coconut fat (CoF). Chicks were distributed according to a factorial 2x2x2arrangement (2 free fatty acids - FFA ) x (2 n6:n3 ratios) x (2 medium-chain fatty acids levels - AGMC). Performance responses and dry matter (DMM), crude protein (CPM), and crude fat (CFM) metabolizability were evaluated. In Experiment II, 480 1- to 20-day-old male Ross 308 broilers were offered the free choice of 2 different diets: with no fat addition, or with 10% addition of the following fat...

Provedor de dados: 89
Autores: Biavatti,MW; Bellaver,MH; Volpato,L; Costa,C; Bellaver,C.
The influence of alternative treatments using fluidextracts of Alternanthera brasiliana, propolis resin and linseed oil on the performance and blood biochemistry of broilers was evaluated. The study was done with five treatments: basal diet (negative control); basal diet + 40 ppm avylamicin and 120 ppm monensin (positive control); basal diet + A. brasiliana extract (180 mL/200 kg of feed); basal diet + propolis extract (200 mL/200 kg of feed) and basal diet + linseed oil (2.5% replacing soybean oil). Propolis and A. brasiliana extracts improved broiler performance from 14 to 21 days, whereas linseed oil had no effect. The findings of this experiment revealed that A. brasiliana and propolis extracts can be used as antimicrobials, but further studies are...

Provedor de dados: 96
Autores: Keum,Moung-Cheul; An,Byoung-Ki; Shin,Kyoung-Hoon; Lee,Kyung-Woo.
ABSTRACT This study was conducted to investigate the effects of dietary fats (tallow [TO] or linseed oil [LO]) or conjugated linoleic acid (CLA), singly or in combination, on laying performance, yolk lipids, and fatty acid composition of egg yolks. Three hundred 50-week-old laying hens were given one of five diets containing 2% TO; 1% TO + 1% CLA (TO/CLA); 2% LO; 1% LO + 1% CLA (LO/CLA); and 2% CLA (CLA). Laying performance, egg lipids, and serum parameters were not altered by dietary treatments. Alpha-linolenic acid or long-chain ω-3 fatty acids including eicosapentaenoic and docosahexaenoic acids were elevated in eggs of laying hens fed diets containing LO (i.e., LO or LO/CLA groups) compared with those of hens fed TO-added diets. Dietary CLA, alone or...

This study was carried out to evaluate the effect of supplements with isolated soy protein, brewer’s yeast, a mixture of isolated soy protein with brewer’s yeast, linseed oil, palm oil and mixture of linseed oil with palm oil in the royal jelly production of Africanized honey bee colonies. Total royal jelly produced was superior (P &amp;lt; 0.05) in colonies that were fed with isolated soy protein and brewer’s yeast (11.68g/colony), followed by linseed oil and palm oil (11.30g/colony) and palm oil (9.61g/colony), and the latter higher than controls I (6.35g/colony), and II (6.95g/colony). Thus, mixed supplements are viable to optimize this beekeeping activity in commercial scale.

The aim of the study was to examine the changes in milk fatty acid (FA) profile of grazing buffaloes fed either low (L, 276g/d) or high (H, 572g/d) doses of a blend (70:30, wt/wt) of soybean and linseed oils. Fourteen multiparous Mediterranean buffaloes grazing on a native pasture were fed 4 kg/day of a commercial concentrate containing no supplemental oil over a pre-experimental period of ten days. The baseline milk production and composition and milk FA profile were measured over the last three days. After this pre-experimental period the animals received the same concentrate added with either the L or H oil doses for 26 additional days. Milk yield (g/animal/day) did not differ at the start (1776 ± 522 and 1662 ± 291 for L and H, respectively,...

The objective of this study was to evaluate the incorporation of omega-3 fatty acids (n-3 FA) on male Swiss mice livers receiving diets based on linseed oil (LO) for up to 56 days. The mice were sacrificed at 7, 14, 28, 42, 56 days and FA concentration was analyzed by gas chromatography. A total of 13 FA were identified on LO feeds presenting alpha-linolenic acid (LNA) contents of 26.97 %. A total 22 FA were identified in the livers of the mice. Part of the LNA was converted into n-3 FA (20:3n-3, eicosapentaenoic acid-EPA, 22:5n-3, and docosahexaenoic acid-DHA), and some of the LNA was stored in the liver. LNA, EPA and DHA concentrations (mg/g total lipids ) from 0 days for up 56 days increased from 1.29 to 18.90 (LNA), 0.20 to 18.90 (EPA) and 41.26 to...

Autores: Brestenský,Matej; Nitrayová,Soňa; Patráš,Peter; Heger,Jaroslav; Nitray,Jozef.
ABSTRACT: In the present study it was evaluated the effect of the addition of linseed oil, inulin and horse chestnut added to a high fat (HF) diet on the content of fatty acids (FAs) in musculuss longissimus dorsi (MLD) of pigs. A 5d with adaptation period was followed by a 70 d experimental period, during which the pigs were fed with a HF basal diet. The HF basal diet which served as a control (group CG) was supplemented either with linseed oil (group LG) or with inulin and horse chestnut (group IG). All of the pigs were slaughtered at the end of the experiment and samples of MLD were taken for FA analysis. The concentration of α-linolenic acid in MLD of the LG group was 58 % and 61 % higher (P˂0.05) compared to CG and IG groups, respectively. The content...
