An experiment was conducted to study the effect of different dietary fatty acid profiles on abdominal fat deposition in broilers. Diets with four types fats (tallow, olive oil, sunflower and linseed oil), at two levels inclusion (either 6 or 10%), were administered males from 21 42 d females 49 age. The sexes studied separately. Performance parameters, fat, muscle cholesterol, profile thigh, breast, determined. Broilers fed oils presented better values feed efficiency. Abdominal cholesterol...
The aim of this study was to determine the effect different dietary fatty acid profiles on efficiency energy, fat, nitrogen, and deposition in broiler chickens. Sixty female chickens were fed a basal diet without additional fat or with 4 other diets fats (tallow, olive, sunflower, linseed oils) at 10% from 28 48 d age. Among broilers added those oil had less abdominal (in grams percentage) than tallow (P < 0.05). Absorbed losses slightly higher for birds oil, nitrogen lower However, there...
Two experiments were carried out to evaluate the effect of dietary addition yeast cell wall (YCW); beta-1, 3/1, 6-glucan (BG); and mannoprotein complex (MP) purified fractions in broilers. In experiment 1, there was a control diet 5 experimental diets containing, respectively: 10 mg avilamycin (AVI)/kg feed, 500 YCW/kg 95 MP/kg 145 BG/kg MP plus feed. All birds vaccinated via drinking water against Newcastle disease virus at 9 d age. At 42 d, chickens fed AVI, YCW, + BG, BG had similar BW...
The effect of continuously feeding the probiotic microorganism Toyocerin to birds inoculated with Salmonella Enteritidis field-isolated strains on prevalence, and performance variables were studied in 2 experiments. experiments performed 1) broiler chickens floor pens until slaughter 42 d age, challenge was 3, 7, or 14 x 10(6) cfu per chick, 2) Single Comb White Leghorn cages 28 7 10(8) chick. inclusion feed did significantly (P < 0.05) improve ADG (by 3.4 g), BW 141 conversion ratio -0.060...
Intramuscular fat is an important quality trait in pork. Lysine and protein have been reported to influence this trait, but most studies modified both factors simultaneously. In study, the effects of dietary Lys were investigated finishing pigs determine if either 2 alone or combination deposition intramuscular fat. One hundred four barrows (Landrace × Duroc) fed 1 4 experimental diets, including control protein-control (CPCL), protein-low (CPLL), low (LPCL), diets (LPLL) with 10 pens per...
Two experiments were conducted in order to determine the effect of dietary fatty acid profile on deposition body fat, carcass and separable fat depots. Diets with four types (tallow, olive, sunflower, linseed oils) at an inclusion level 10% administered female broiler chickens. In Experiment 1, total (total minus abdominal fat), (AF) determined. 2, several depots (abdominal, neck, sartorial, mesenteric fat) removed weighed. general, analyzed reduced broilers fed sunflower or oils respect...
The aim of this study was to determine the effect different dietary fatty acid profiles on main fat depots broiler chickens: skin including s.c. (SK) and abdominal pad (AF). One hundred forty-four female chickens were fed a low-fat diet (B; 0.5% added fat) or diets supplemented with 10% tallow (T), sunflower oil rich in oleic (SOO), linoleic (SOL), linseed linolenic (LO), mix fats (M: 55% T + 35% LO SOL) that contained one-third each saturated acids, monounsaturated polyunsaturated acids....
The objectives of this study were to investigate the effects dietary fat (6% lard and sunflower olive oil) supplementation α-tocopheryl acetate or β-carotene on vitamin E content lipid oxidation in raw, cooked, chilled-stored broiler leg meat. Vitamin increased its tissue level, reducing oxidation. oxidative stability meat tended decrease with oil. Effects levels depended concentration feed, decreasing E, mainly at 50 ppm. β-Carotene 15 ppm acted as antioxidant fresh cooked oil diets....
The objective of the study was to determine effects two enzyme preparations containing beta-glucanase and xylanase activities on barley- wheat-based diets, respectively, for broilers, in combination with flavomycin. In addition, stability after pelleting measured. Temperatures recorded during process reached 75 80 C, recovered respect amounts present mash feed before were 80% or higher. Two performance experiments conducted simultaneously under same conditions over 6 wk. intestinal viscosity...
Previous experiments have shown lower abdominal and body fat deposition in broilers fed polyunsaturated fatty acids (PUFA) compared with those saturated (SFA) or monounsaturated (MUFA). These changes may be related to different rates of lipid synthesis oxidation. In Experiment 1, vivo lipogenesis dietary acid profiles (tallow, sunflower oil, linseed oil) was investigated. 2, liver a basal diet (without additional fat) diets added tallow, olive oil studied. Results from 1 showed higher de...
Benefits from probiotic micro-organisms have been recognised for over 100 years, and as being useful in poultry 50 years. Fuller (1989) redefined probiotics 'a live microbial feed supplement which beneficially affects the host animal by improving its intestinal balance'. derived this improved balance could be reflected performance or prevention of pathogen colonisation. Probiotic use production has widely accepted new opportunities arose 2006 EU ban on antimicrobial growth promoters. The...
The objective of this study was to assess the effects a probiotic strain Clostridium butyricumMIYAIRI 588 (CBM588) on broiler and weaned piglet health zootechnical performance. Five field studies were carried out in broilers five piglets under European feed additive guidelines. Each followed randomized blocked design with two treatments: Control (basal diet) CBM588 supplemented groups. performance parameters selected body weight, daily gain, intake efficiency (feed:gain). Broilers fed diets...
An experiment was conducted to study the effect of different dietary fatty acid profiles on plasma levels insulin, very low density lipoproteins (VLDL), cholesterol, and glucose. Diets with four types fat (tallow, olive, sunflower, linseed oils) at an inclusion level 10% a basal diet without additional were administered female broiler chickens. Serum VLDL affected by treatments; however, glucose concentrations similar among treatments. In fasted state, broilers fed diets sunflower or oil...
The objective of this study was to investigate the effects dietary fat (lard, sunflower oil, and olive oil) supplementation α-tocopheryl acetate or β-carotene on descriptive sensory changes in broiler leg meat as evaluated by a trained panel. Twenty-five descriptors were analyzed from chicken meat: 11 raw 14 cooked meat. Rancid values very low, possibly because samples consumed between 1 4 d after slaughter, which maybe insufficient time for oxidative processes decrease quality. However,...
Little is known about pig gene expressions related to dietary fatty acids (FAs) and most work have been conducted in rodents. The aim of this study was investigate how fats regulate fat metabolism pigs different tissues. Fifty-six crossbred gilts (62 ± 5.2 kg BW) were fed one seven treatments (eight animals per treatment): a semi-synthetic diet containing very low level (no (NF)) six fat-supplemented diets (ca. 10%) based on barley soybean meal. supplemental sources tallow (T), high-oleic...
Abstract 1. An experiment was conducted to compare the relative bioefficacy of DL‐methionine hydroxy analogue free acid (DL‐MHA‐FA) with in broiler chickens. Responses used for comparison were weight gain and food efficiency between 7 35 d age, breast meat deposition, cost per kg meat, abdominal fat at 41 age. 2. A total 2160 seven‐day‐old male chicks used. The feeding programme consisted a starter diet from 21 d, finisher till end experiment. basal contained 6.1 g/kg sulphur‐containing...
