The objective of the research was to evaluate to effect of feeding mengkudu on performances of broilers. The research design used was completely randomized design. One hundred broilers were distributed into five treatments. The treatments were different levels of mengkudu meal (0, 0.75%, 1.5%, 2.25 % and 3%). The observed measured were feed consumption, average body weight (gain) and feed conversion. Results showed that feeding mengkudu (Morinda Citrifolia L.)  no effect significant (P>0.05) on feed consumption, average body weight and feed conversion.  In conclusion, feeding mengkudu meal up to 3% (in diet) does not negatively affect feed consumption, average body weight, and feed conversion.

Background : Female menstrual changes in hormone concentration influence appetite and eating behavior. As well, eating pattern has some influences on menstrual hormonal status. Feeding date palm fruit has been found in our previous report to affect menstrual hormones and some menstrual parameters. Objective: The aim of this research is to study the effect of feeding dates on energy, macronutrient, and fiber intakes, body weight, and body fat%. Additionally, this study aims to find any correlation between menstrual hormone concentration and the above-mentioned parameters. Methods: A convenient sample (n=37) of not-sexually active females aged 20-30 were divided into two groups; one group (dates group) was fed 7 dates and the other served as a control group. The participants of the control group were exposed to the same experimental conditions except for eating dates. Throughout the feeding trial, the volunteers filled a 3-day food record; one menses day and two non-menses days. Results: There was a significant effect of the menstrual status-feeding duration interaction in terms of protein and fat intakes. Additionally, menstrual status, as well as feeding duration, affected energy and macronutrient intakes significantly. Furthermore, feeding duration affected fiber intake significantly. Despite the above-mentioned differences in energy and macronutrient intakes, these effects didn’t affect the body weight and body mass index of the study participants, neither their body fat%. Moreover, we have found significant correlations between nutrient intakes and menstrual hormone concentration. Conclusion : Feeding dates affected energy, macronutrient, and fiber intakes significantly. These effects were related to the changes in menstrual hormone concentration.

The research was conducted on the effect of bird broilers fed with different hybrid rye doses on the fatty acids profile in muscle. The first experiment was performed on 3 geese broilers groups fed with hybrid rye, oats or hybrid rye and oats mix in proportion 1:1. No effect of the hybrid rye feeding of geese on the SFA level in meat was observed, but the MUFA level was significantly higher and PUFA level and n-6/n-3 PUFA ratio were significantly lower than in geese fed with oats. The second experiment was performed on 3 chicken broiler groups fed with mix of corn, wheat, soybean meal and rapeseed oil (control group), and fed with an addition of 10% or 20% hybrid rye in diet (experimental groups). No effect of hybrid rye feeding of chicken broilers on the meat quality and SFA level was observed. However, the MUFA level was higher and the PUFA level and n-6/n-3 PUFA ratio were lower in meat of chicken broilers fed with hybrid rye. In conclusion hybrid rye is a healthy ingredient in the diet of studied birds and may be used up to 20% in chicken broilers and 50% in the diets of geese. A 100% hybrid rye in geese diet caused lower final body weight.

Abstract The objective of this study was to determine the effects of an immunomodulatory feed ingredient during post-weaning on growth and cortisol levels of beef heifers. Commercial Angus heifers (n = 72) from two AI sires were blocked (n = 9) by sire and BW and then randomly assigned to one of two pens per block. Each pen (4 heifers/pen) per block was assigned to one of the treatments. Heifers were fed a commercial TMR twice daily from d 0 to 60 to gain 0.75 kg/day. The feed was top-dressed once a day with either 72g of Celmanax (CEL) or 72g of corn germ (CON) per pen. Body weight was collected on d -1, 0, 15, 30, 45, 60 and 61. Blood samples were collected on d 0, 15, 30, 45 and 60. Sixteen heifers (n = 8 CEL; n = 8 CON) were randomly selected for a corticotropin releasing hormone/ arginine vasopressin (CRH/AVP) challenge after the 60 d period. Two heifers per pen (n = 32) were randomly selected for a transportation challenge to evaluate stress response on d 61 or 62 of the study. Pen was the experimental unit and data was analyzed by ANOVA or repeated measures analysis as appropriate. Feed efficiency and BW gain was increased (P = 0.04) in CEL heifers compared to CON heifers. Serum cortisol concentrations were decreased (P < 0.01) in CEL heifers compared to CON heifers on d 30 to 60 post-weaning. Serum cortisol concentrations were decreased (P < 0.05) in CEL heifers compared to CON heifers during the CRH/AVP challenge from 60 to 150 minutes post infusion. Serum cortisol concentrations were decreased (P < 0.05) in CEL heifers compared to CON heifers throughout the transportation challenge. In summary, supplementation of Celmanax post-weaning increased BW gain and reduced cortisol concentrations in beef heifers.

The present study was conducted in 20 growing female Mehsana buffalo calves to study the effect of feeding cotton seed cake with the objective to increase growth and blood biochemical profile. Mehsana buffalo calves of 3-6 months of age were randomly divided in two groups on the basis of body weight and age. Group I was control (T1) fed Banasdan (concentrate mixture) whereas, group II (T2) was fed with cottonseed cake @ 700g, 850g and 960g for 1st, 2nd and 3rd month of treatment, respectively in addition to concentrate feed. Both the groups fed green fodder @ 3kg and dry fodder @ 1kg per day throughout the experiment. Body weights of individual calves were recorded at the commencement of the experiment and followed by monthly interval. Blood- biochemical constituents were recorded on day 1 and thereafter on day 90 of experiment period to analyze the changes in blood constituents in T1 and T2 groups. Average daily body weight gain of calves during the experimental period was higher (P less than 0.01) in T2 group as compared to T1 group. The serum glucose level was higher (P less than 0.05) in T1 group than T2 on day 90. The values of serum cholesterol, protein, globulin, ALP, SGOT and SGPT concentration were also significantly (P less than 0.01) higher in T2 group than T1 on day 90. However, the differences for serum albumin, A/G ratio, calcium and phosphorus on day 90 were found to be non-significant whereas metabolic hormone level T3 and T4 were significantly (P less than 0.01) higher in T2 than T1 on day 90. The results are indicative of supplementation of cotton seed cake in addition to Banasdan accelerated the growth, blood biochemical parameters and hormonal levels.
