Weaning is associated with several stress factors and their effects on the piglet's body are fairly well known. Thus, changes were estimated in certain serum and faecal parameters after weaning owing to dietary protein level, though essential amino acid (AA) levels were maintained or reduced. Eighteen Topigs piglets were assigned randomly to three homogenous groups. The dietary protein level was reduced by 10% in diets 1 and 2 compared with diet C. Diet 1 had similar levels of essential AA to diet C, while the levels of essential AA in diet 2 were reduced by 10%. Blood samples were collected by jugular venipuncture in the farrowing unit on four occasions: Before and after separation from the sow; the day after transfer to the nursery; and seven days after weaning. Faecal excreta were collected daily. No major health problems arose, and total pathogen germs were not different among treatments. Cortisol concentration reached similar values to those from the farrowing unit seven days after weaning. Whatever the diet, vitamin E in plasma decreased significantly in the first seven days post weaning. The reduction of dietary protein, as well as essential AAs, adversely affected the concentration of Cu (by 17.3%) in plasma. Selenium concentration in plasma increased slightly, irrespective of diet. The authors conclude that providing dietary protein at a particular level (diet 1), while maintaining AAs at normal level, limits faecal nitrogenous content without significantly modifying stress indicators (except vitamin E) or faecal composition.

The purpose of this study was to investigate the effect of the dietary mulberry leaves on nutrient digestibility and layer performances. The experiment was conducted for 30 days on 105 Lohman Brown layers assigned to 3 groups (C, E1 and E2) with 35 layers/group. The experimental diets included 3% (E1) and 6% (E2) mulberry leaves. The layers had free access to the food. The feed intake, egg production, feed conversion ratio, egg mass production and egg weight were recorded; no significant difference was noticed between the 3 groups. Digestibility studies were performed on weeks 2 and 3 (5 days/week). Organic matter digestibility was significantly higher in the control group compared to the experimental groups: E1 and E2. Nitrogen free extractives significantly differed in groups too. The physical parameters of the eggs (egg weight, egg white weight, egg shell thickness, Haugh unit, egg yolk weight and egg shell weight) did not differ significantly between the groups. Yolk colour intensity was significantly higher in the experimental groups E1 and E2 compared to the control group. Use of mulberry leaves in laying hens nutrition by including into ratio up to 6% had no negative effects on breeding performances and egg quality.

The purpose of this study was to investigate the effect of the dietary mulberry leaves given to broiler chicken on their performance and on the quality of the breast meat. The experiment was conducted for 4 weeks, on 114 broilers, aged 21 days. The broilers were assigned to 3 groups (C, E1 and E2) with 38 animals per group. The diets for groups E1 and E2 also included mulberry leaves 2 and 5%, respectively. The birds had free access to the feed and water. The average daily feed intake (g/day/broiler), average daily weight gain (g/day/broiler), final weight (g) and feed conversion ratio (g feed/g gain) were not significantly different among the 3 groups. The fatty acid content of the breast muscle had the following evolution: the concentration of saturated fatty acids decreased, while the concentration of polyunsaturated fatty acids increased by 14.53% in groups E1 and 25.58% in E2 compared to the control group, the difference between groups E2 and C being significant. The cholesterol concentration decreased in the experimental groups, the difference between groups E2 and C also being significant. The inclusion of up to 5% mulberry leaves in broiler diets did not have adverse effects on broiler performance, while it increased the quality of the breast muscle by decreasing the concentration of saturated fatty acids, omega 6 (n-6) to omega 3 (n-3) ratio, and also the concentration of cholesterol. © 2015 Indian Journal of Animal Sciences.

The experiment assessed the fatty acids (FA) composition of Longissimus dorsi (LD) muscle and plasma polyphenols spectrumin finishing hybrid Topigs fed diets containing dried grape pomace (DGP). The trial was conducted on 24 hybrids Topigs, 75.54±5.55 kg, randomly assigned for 28-d experimental period, to 2 groups, viz. a control (C diet), and an experimental (E diet) with the additional inclusion of 50 g DGP / kg diet. The FA composition wasanalysed by gas chromatography and all the spectra were recorded by spectrophotometry. The results of the study prove that the DGP, by its high content of polyunsaturated fatty acids (PUFA, over 60% of total FAME) and by the active principles such as polyphenols (lmax =273 nm), is a valuable feed which improvedfatty acids composition of LD muscle. In addition, the polyphenols from GP changed in plasma, maximum changes from 273 nm to 279 nm. These properties were reflectedin a positive influence on muscle n-3 FA composition (>1.27 times in DGP group than control group, p=0.02), particularly alpha-linolenicFA (>1.35 times) and eicosapentaenoic FA (>1.30 times than C diet), known for their health benefits.

The study was conducted using 21 Romanian Black Spotted fattening steers to determine the effects of sorghum grains on health and fatty acid profile of Longissimus dorsi muscle. The animals were assigned uniformly to 3 groups of 7 steers each, which received different treatments: control (C) received a compound feed without sorghum grains, experimental group (E1) received 15% sorghum grains in the compound feed, while next experimental group (E2) received 25% sorghum grains in the compound feed. To determine the biochemical parameters, blood samples were collected from animals at the end of experimental period. The laboratory analyses conducted on samples of Longissimus dorsi muscle collected from the 3 experimental groups, showed changes in the fatty acid composition. The proportion of saturated fatty acids (SFA) decreased in favour of the unsaturated fatty acids (UFA) with 1.04% in group E2, while the proportion of unsaturated fatty acids increased from 53.00% in the control group to 54.19% in group E2.
