Quantitative Measurements

Patterns of growth can be determined one of them through quantitative measurements, namely osteometry. The aim of this study was to determine the growth of patterns of Lohmann broiler chickens based on hindlimb osteometry at the age of 7, 21 and 35 days. This study used 30 Lohmann broiler chickens aged 7, 21 and 35 days. Osteometry techniques are performed on all the bones of hindlimb with variable Greatest length (GL), Breadth of the proximal end (Bp), Breadth of the distal end (Dd), Minimum breadth of diaphysis (Sd), Circular of the proximal end (Cp), Circular of corpus (Cc), and Circular of distal end (Cd). The data obtained is recorded in units of centimeters (cm). Data of body weight and weight of each bone are also recorded in grams (g). Data were analyzed by ANOVA test, if the result obtained with a significance of 5% then the test continued with Pos Hoc Duncan. The results showed that from 6 osteometry variables, body weight, and bone mass obtained significant differences (p<0.05). The fastest growth rate is reached when Lohmann broiler chickens are 21 days old.

Selection Of

Two trials were conducted with Nicholas strain turkeys. In trial 1, 300 male poults were reared to 49 days using either initial stages of 'large-turkey' feeding regime, or a situation allowing for diet self-selection of protein and energy. Within these programs, diets were supplemented with 10 ppm avoparcin, while a comparable number of controls received no growth promoter. Avoparcin improved growth rate (P < 0.01) irrespective of age, and improved feed utilization to 35 days of age. This effect was not confounded with the form in which diets were offered. In a second trial a 'broiler-turkey' feeding schedule was used, with birds slaughtered at 88 days. Diet treatments consisted of a control diet containing 33 ppm robenz and test diets containing either 33 ppm robenz + 10 ppm avoparcin or 10 ppm avoparcin alone. Avoparcin improved weight gain (P < 0.05) irrespective of coccidiostat inclusion. Feed utilization and carcass grades were not influenced by diet. The 7% improvement in body weight noted here with avoparcin was substantially greater than that previously observed with broiler chickens.

The Mean

Three commercial premix types were fed in and duplicated to six groups of 45 broilers each at the starter pbase (0-5 weeks). At the finisher phase (5-9 weeks) each treatment group of the vital roles in starter was further divided into three groups. Nine premix combinations were used at the finisher pbase. Performance of the birds was monitored. At the starter phase, birds fed premix Z diet had a mean body weight blood (629.90gm) that was higher (P<0.05) than fed premix A diet (518.87 gm) which was also the maintenance of osmotic relations and acid higher than those fed premix U diet (414.59gm). The mean daily weight gain followed the same  trend with 16.81gm, 14.04gm, or 10.58 gm for birds fed diets that contained premixes Z A or U respectively. Birds fed a diet that contained premix Z consumed 48.80 gm daily which was  more than those for birds fed premix U in their diet (37.85gm). The feed to gain ratio was not significantly affected (P>0.05) by the premix  type fed at this phase. Poor growth rate caused by premixes with marked differences in their by premix fed at the starter phase was not completely overcome due to the premix type fed at the finisher phase varied (P<0.05) with the type of premix fed. No difference (P>0.05) was observed among the  premix types for the metabolic trials at the starter phase.

Three experiments were conducted to test the effects of Lipo-adrenal cortex (LAC), cortisone acetate (CA), hydrocortisone acetate (HCA) and glucagon (G) in broiler chickens. Oral administration of 38.7, 69.6 or 96.8 mg CA per bird significantly retarded body weight gain between days 14 and 21. HCA administered intramuscularly in doses varying from 2 to 24 mg/100 g of body weight significantly decreased body weight gain between days 14 and 28. Shank growth was similarly affected by doses over 4 mg HCA. The same doses significantly increased liver weight. At 3 months of age, birds recovered from growth retardation caused by the injection of 4 mg HCA/100 g of body weight at 14 days of age. Experimental results indicate that 2 or 4 mg HCA/100 g of body weight, administered by one injection at 14 days of age, may be used to increase growth rate variance by retarding growth.

Rapid growth rate in broilers is always followed by a rapid fatty liver, in which fat storage tends to increase with increasing body weight. The rapid growth in broilers that are often followed by a fatty is higher, it becomes a problem for consumers who want a chicken with a low fatty. The purpose of this study was to determine the effect of adding the juice of betel leaves to body weight of broiler chickens. This research was conducted in 9 March to 6 April 2014 for 28 days at Hamlet Village Kedungrejo Salamrejo Binangun District of Blitar. This research used an experimental method that uses a completely randomized design (CRD) using 4 treatments with 5 replicates, each replicate consisting 5 Broiler. The Results showed the treatment had no significant effect (P = 0.05) on body weight. Based on statistical calculations did not show any differences. The absence of significant differences is due to the weight of the chicken that uniform between treatments and content of feed used primarily energy and protein in the diet is almost the same.Keyword : Betlle Leaf Juice, Broiler Again, FCR

Three different brands of commercial premixes were fed to a total of 270 Brown Hypeco breeds of broilers at starter and finisher stages of development. At the starter phase the broiler chickens were divided into three experimental groups. Each group was fed one type of premix in duplicates and designated A, B and C. At the finisher phase, each of the 3 groups was divided into 3 experimental group to obtain a total of mine premix combinations. Data on growth rate, feed and energy intake were recorded from which weight gain and energy efficiency were calculated. The results showed that broilers fed premix B at both development stages had better body weight and gain (20.59g/day), comsumed more DM (56g/day), energy (168 kcal / day) with better energy efficiency than broilers in other groups. Energy efficiency of broilers fed premix A was better than that of C – fed broilers at finisher phase. Energy efficiency was improved when broilers were finished with premix B irrespective of the starter premix. The poor energy efficiency of broilers fed premix A or C was attributed to deficiency of thiamine and marginal deficiency of other energy related micro-nutrients leading to nutrients imbalance.

Prenatal Effects

Light during incubation can influence embryonic and postembryonic development of chickens, but the underlying mechanisms are poorly understood. Previous studies have demonstrated that red and blue lights during incubation had opposite effects on the development of embryonic melatonin biosynthesis; red light results in the highest and blue light in the lowest amplitude of the daily rhythm. Therefore, in this study, we investigated if exposure to monochromatic red (632 nm) and blue (463 nm) light during incubation can differently influence growth, selected biochemical (glucose, cholesterol, triacylglycerols) and endocrine (corticosterone and thyroid hormones) traits and behavioural parameters during postembryonic development in broiler chickens. For analysis, we used 10 and 11 hatchlings incubated in red and blue light, respectively and 10 birds per each group (six males and four females) in 3-weeks-old broilers. During the rapid growth phase (days 18, 20 and 21 of age), higher body weight was recorded in broilers incubated under red compared to blue light, whereas endocrine and metabolic traits did not differ between the treatments. The improved growth rate was related to behavioural traits, mainly because chickens incubated in red light exhibited more passive (resting, standing, preening, dust bathing) and less active behaviours (walking, foraging, fighting, wing-flapping) than the blue-light incubated birds. The time spent for eating and drinking and the results of the tonic immobility test did not differ between both groups. Our results suggest that red and blue monochromatic light during incubation can differently program the postembryonic development of broilers, with possible consequences for their growth and welfare.

Growth Promoter

Two trials were conducted to test the effectiveness of a new antibiotic growth promoter, avoparcin, on growth and feed utilization of floor reared, mixed-sex, broiler chickens. Avoparcin 10 ppm, avoparcin 10 ppm + 3-nitro 50 ppm and lincomycin 2.2 ppm were tested in combination with various coccidiostats. To 28d (28 days), birds fed avoparcin were significantly (P < 0.05) heavier than those fed lincomycin, although neither group was heavier than control birds receiving no growth promoter. Growth promoter had no significant effect on body weight at 49d, although the coccidiostat, coban, resulted in a significant (P < 0.05) depression in growth rate. From 0 to 49d, birds fed avoparcin alone showed a significantly (P < 0.05) improved feed intake:body weight gain. In a second trial 10 and 20 ppm avoparcin were tested. Avoparcin 10 ppm resulted in a significant (P < 0.05) 3.7% increase in body weight and 4.1% improvement in feed efficiency at 49d of age relative to control birds. Increasing the level of 20 ppm resulted in no further improvement in these parameters. The effect of avoparcin was independent of the coccidiostats used in this experiment.
