A total of 150 unsexed broilers consisting of 75 Abor Acre and 75 Cobb were randomly allotted into 5 treatments of 15 birds for each strain. Treatment one (T1) had no scent leaf meal (control); treatment two (T2), treatment three (T3), treatment four (T4) and treatment five (T5) had 0.5%, 1.0%, 1.5%, and 2.0% throughout the experimental period (56days). Blood samples and carcass characteristics were evaluated after the feeding trial and subjected to analysis of variance in a completely randomized design. Results revealed that diets and strain significantly (P < 0.05) affected live weight, dressed weights, and dressing percentages. T3 had the highest live and dressed weight (2091.50 ± 85.27 g and 1737.67 ± 22.16 g), while T5 recorded the lowest (1700 ± 102.47 g and1253.17 ± 68.09 g). Cobb was superior to Arbor acre for all carcass traits except for leg weight. Red Blood Cell, White Blood Cell, Mean Corpuscular Volume, Mean Corpuscular Haemoglobin and Mean Corpuscular Haemoglobin Count of the two strains were significantly (P < 0.05) different, while Pack Cell Volume, Haemoglobin, Neutrophils, Lymphocytes, Monocytes, Eosinphils and Basophils were not significantly different (P > 0.05). This study revealed no detrimental effect of the test ingredients on birds, though 1.5% inclusion rate could be tolerated, 1.0% is recommended for optimum performance, and can therefore efficiently replace synthetic antibiotic in broiler production.","PeriodicalId":17946,"journal":{"name":"Large Animal Review","volume":"204 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76201631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Total of 200 one- day-old unsexed chicks were used, and divided into two pens/groups (100 birds of each with 25 birds of each replicate), at stocking density of 8.7 bird/ square meters. First pen used for LED white color and second pen for LED blue- green mix color light. The results showed that the birds exposed to blue-green light had significant higher (P≤0.01) BW, DBWG and FC values of the whole experimental period compared to those exposed to white color. However, the light color had no significant effect on FCR and MR measurements with average values 1.44 and 0.50%, respectively. The birds exposed to blue-green light had significant higher pre-slaughter live BW and carcass weights (P≤0.01) compared to those exposed to white color. The birds exposed to blue-green light had higher insignificant dressing percentage compared to those exposed to white color. The weekly behavior results showed highly significant differences (P≤0.01) among weeks for aggressiveness and immobility activities, while it being insignificant for pecking activity. The correlation value between immobility and five-week BW of birds reared under blue-green light was the only significant value (0.42) among all studied values. In conclusion, the results indicated that Cobb broilers were calmer under blue-green light compared to those reared under white light, which contributed in more better performance traits.","PeriodicalId":17946,"journal":{"name":"Large Animal Review","volume":"35 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83407038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first week all chicks fed starter basal diet, however during the second week, broiler chicks were exposed to feed restriction by feed withdrawal time (0, 6, 9, 12 hours/day). Broiler chicks exposed to feed withdrawal had low body weight gain and feed consumption at 2 weeks of age. Feed withdrawal had no effect on final weight, body weight change, total feed intake, total feed conversion, economic efficiency, carcass traits and serum blood composition of 42-day-old-broiler chicks. Feed withdrawal and feed additive in broiler diets decreased total microflora counts and E coil and enhanced lacto Bacillus, amylase and chemo trypsin in broiler guts. Feed additive (Progut®) decreased total feed consumption, improved total feed conversion and increased economic efficiency of broilers. Feed additive increased the level of β globulin and decreased the level of α globulin in serum blood of broiler chicks. The obtained results suggested that feed withdrawal during the second week of age had not effect on broiler performance, carcass traits and serum blood characteristics and improved lacto Bacillus, amylase and chemo trypsin.

Twenty-seven goats (15 buck and 12 pregnant does) were used in this experiment. The bucks and gravid does were fed same experimental diet once daily at either, 06:00h, 12:00h or 18:00h in the morning, afternoon or evening, respectively. Rectal temperature (P<0.001) of bucks fed at 18:00h was higher than 12:00h fed bucks which was higher than 06:00h fed bucks. In contrast, pregnant does fed in the evening had lowest (P=0.009) axillary and rectal temperature while afternoon-fed does had the highest. Time of feeding induced increase (P<0.001) in axillary and rectal temperature of the bucks and pregnant does. The excursion ranges of temperature of morning, afternoon and evening-fed bucks was 0.42-0.79, 1.11-1.25, 1.15-1.19 o C, respectively, while the excursion range of temperature of morning, afternoon and evening fed bucks was 0.17-0.19, 0.55-0.72, 0.45-0.47 o C respectively. This study shows that time of feeding can entrain body temperature and animal physiological state can affect the temperature rhythm of animals. In conclusion, feeding bucks or pregnant does in the morning or evening may be an effective strategy to manage heat stress in measuring time for the three times measurement per week. It shows that the time does were fed actually entrained the pattern of distribution of their temperature. In the morning-fed does, the temperature rhythms were fairly consistent throughout the day for each week. In evening and afternoon-fed does, the temperature rhythms greatly fluctuate.","PeriodicalId":17946,"journal":{"name":"Large Animal Review","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90472265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
