Quantitative Genetic Traits

The aim of this study is to characterize some quantitative traits of Noi chicken, one of the Vietnamese famous native breeds for meat quality and fighting, at the stage of 0-28 days old. Therefore, 742 chicks were used to measure, record, analyze and evaluate on these traits. As results, there was significant difference in observation traits among stages of age (P=0.000). Interesting, the wings (+64.88%) and keel lengths (+58.83%) rapidly developed within the first week of life, followed by the most of other dimensions, especially breast diameter (+31.85%), thigh diameter (+71.17%) in the second week of age. An increase in the size of the measurements was due to development of the skeleton at observing time points along the experiment. However, there was strong development of muscle tissue in the second week of life as rate of the breast and thigh diameter was greatest. Noi chicks consumed amount of feed of 16.54 g/bird/day and gained a weight of 6.98 g/bird/day. Thus, their feed conversion ratio was 2.37 at the stage of 0-28 days old. Perhaps a direct positive relationship between observed traits and age were randomly established according biological characteristics of animal. This work provided initial benchmarks of Noi chicks for further studies.

The objective of the study is to compare the practical results with the predicted results by Crossbreeding Effects (CBE) software on pig crossbred based on daily gain, backfat thickness and feed conversion ratio. Another purpose of this study is to predict those three traits among some expected hybridization. This research was conducted on pig farm at Binh Thang Research and Development center from 2013 to 2017. In this study, for each pair of purebred Duroc and Pietrain, Duroc and Landrace, Pietrain and Landrace, twelve hybridizations were analyzed, nine unhybridizations were predicted by CBE software. The results showed that there was no significant difference between the predicted and actual data. With some unhybridization crossbred , the predictions showed high reliability (P<0.05). Based on the predicted data of CBE software , some traits of the crossbred animals would not be improved, therefore, it was not necessary to conduct these hybridizations

Performance and organoleptic indices of rabbits fed plantain, oil palm and calopogonium leaves was assessed using 48, eight weeks old bucks. They were allotted to four groups of 12 animals and three replicates of four animals each. Group A (control) was fed calopogonium leaf while groups B, C, and D were fed plantain leaf, oil palm leaf, and 50% oil palm + 50% plantain leaves, respectively. Animals consumed fixed amount of commercial pellets while forages and water were given ad libitum. Completely randomized design, one-way analysis of variance was used. Proximate analysis of pellets and forages as well as feed intake, weight gain and feed conversion ratio were assessed. At the end of the experiment, meat from one rabbit per treatment was used for sensory evaluation by 20 semi-trained panelists using 7-point hedonic scale. Data were analyzed using SPSS software. Significant means were separated using Least Significant Difference. Crude protein, crude fibre, ether extract, nitrogen free extract and ash contents of the leaves ranged from 25.11±1.50 (calopogonium) to 4.90±0.92 (oil palm), 38.40±2.12 (oil palm) to 15.38±0.07 (plantain), 9.71±0.01 (plantain) to 2.30±0.01 (oil palm), 47.80±0.56 (oil palm) to 32.27±0.02 (calopogonium) and 11.93±0.02 (plantain) to 2.99±0.01 (oil palm), respectively. Groups A and B had the highest (p<0.05) final weight and weight gains while groups A, B and C had the highest (p<0.05) forage intake. Feed conversion ratios of groups A and B were better (lower) than others. Forages had no effect on meat colour and texture. Groups B and D meats tasted better than others. Group D meat aroma was better than those fed single forages. Meats from groups C and D were the juiciest while meats from groups A, C and D were the most acceptable. Consideration of final weights, weight gains, feed conversion ratio and taste of meat would require that plantain leaves be used to feed meat rabbits.

ABSTRACT EFFECT OF SUBSTITUTION OF YELLOW CORN WITH BANANA (Musa paradisiaca) PEELS IN THE DIETS ON BROILER PEERFORMANCE. A study has been conducted to determine the effect of substitution of yellow corn with banana (Musa paradisiaca) peels in the diets on broiler performance. The present study used 60 broiler chicks and reared for 5 weeks. A Completely Randomized Design was used as an experimental design with 4 treatments and 5 replications. Treatments were formulated as follow: R0: diet without substitution of banana peels or 0% in the diet; R1: diet with the substitution of 7,5% or 4,28% in the diet; R2: diet with the substitution of 15,0% or 8,55% in the diet; and R3: diet with the substitution of 22,5% or 12,83% in the diet. Variables measured were: daily feed consumption, daily gain, and feed conversion. Research results showed that daily feed consumption, daily gain, and feed conversionratio were all significantly (P < 0,05) affected by treatments. Daily feed consumption at R3 significantly (P < 0,05) lower compared with R0 and R1 treatments, but no differences (P > 0,05) were observed  between R2 and R3. No significant (P > 0,05) was observed between R0 and R1, but there was a significant difference (P < 0,05) between R2 and R3 and between R1 and R2. Feed conversion ratio was significantly (P < 0,05) lower for R0 compared with R1, R2 and R3, but no differences (P > 0,05) were observed among R0, R1, and R2 treatments. It can be concluded that banana (Musaparadisiaca) peels meal can be used up to 15% replacing yellow corn or 8,55% in broiler diet. Key words: Broiler chicks, Banana    (Musaparadisiaca) peels,        Daily feed consumption,         Daily gain, feed conversion            ratio.

The study was carried out to evaluate the effect of feeding locust bean (Parkia Biglobosa) seed meal (LBSM) at graded levels on the performance of broilers. Two hundred and forty broilers were used which were randomly allotted to four treatment groups, each replicated four times in a completely randomized design. The diets contained 0% level of LBSM which served as the control, while other three diets contained 5, 10 and 15% levels of LBSM. The experiment lasted for 28days. Significant differences of (P<0.05) were observed in feed intake (g/b/d) water intake ml/b/d, final body weight (g/b), body weight gain (g/b) averaged daily gain (g/b/d) and feed conversion ratio (FCR). While no significant effect of locust bean seed meal (LBSM) in broilers diets provide effective mechanism for better performance. But live weight was significantly influenced (P<0.05) by LBSM. Analysis of variance (ANOVA) was used to determine significant difference between treatment groups in term of performance parameters. Where significant difference existed, Duncan’s multiple range test was applied to separate the means. Data analysis was carried out using (SPSS (SPSS, 2013version 20.0).It is concluded that LBSM can be included in the diet of broilers at starter phase from 5-15% inclusion levels while at finisher phase, diets containing 10 and 15% level of inclusion would be used for better performance without any deleterious effect on the growth performance. It could be recommended that, diets containing 10 and 15% LBSM level of inclusion would be used for better performance and economic benefit with better feed conversion ratio.

Evaluation of the efficiency of rapeseed meal (RSM) as an alternative protein source by replacing soybean meal (SBM) in the diets of GIFT strain of Nile tilapia Oreochromis niloticus was carried out in cages installed at Poondi Reservoir, Tamil Nadu, South India. Five isonitrogenous (30% protein) and isolipidic (7% lipid) diets were formulated by incorporating RSM protein by replacing SBM protein at 0 (control diet), 25, 50, 75 and 100% levels (0RSM, 25RSM, 50RSM, 75RSM and 100RSM). Each diet was fed to two replicate groups of GIFT tilapia with a mean initial weight of 20.38 ± 0.07 g for 60 days in cages. GIFT tilapia fishes fed with 75RSM diet attained maximum percentage weight gain, PWG (590.89 %), maximum specific growth rate, SGR (3.22), best feed conversion ratio, FCR (1.03) and maximum protein efficiency ratio, PER (3.23) among the treatments. The fishes fed with 0RSM, 50RSM and 100RSM diets showed no significant difference (p>0.05) in mean weight gain, MWG, SGR, FCR and PER. No significant difference in hepatosomatic index, HSI was found among the fishes fed with 0RSM, 75RSM and 100RSM diets. There was no significant difference (p>0.05) observed in survival between treatments. The whole body proximate composition (moisture, protein, lipid and ash) of GIFT tilapia did not differ significantly (p>0.05) among the treatments. It was concluded that, rapeseed meal can completely (100%) replace soybean meal protein in the diets of cage cultured GIFT tilapia in reservoir, without compromising growth, feed conversion ratio and whole body composition.

The aim of the study was to evaluate the effect of grass pasture on the performance of slowly growing chickens. Both sexes (72 chickens) of the slowly growing hybrid Hubbard JA 757 were used in the experiment, which was carried out in the summer 2015. The chickens were divided into two groups with six replications. After 34 days of age, half of the chickens were transferred to outdoor fields to the transferable cages (EXP). The second half of chickens stayed in the house in a controlled microclimate condition. The live weight of chickens at 63 days of age was 2.93 kg in the EXP and 3.14 kg in the CON, and there was no significant difference between the groups (P > 0.05). However, the live body gain between 34 and 63 days of ages was significantly affected by the pasture (P ≤ 0.01), and it was 2.02 kg in EXP and 2.45 kg in CON. Feed conversion ratio during the experimental period was also significantly different in the groups (P ≤ 0.01), 2.60 in EXP and 1.97 in CON. High average daily temperature 28.7 °C had a main negative effect on the performance of chickens.

Catfish is one of the fish that has a high economical value. Catfish is accepted by society easily because of its advantages. These advantages include fast growing, good adaptive behavior, good taste, high nutrient, and cheap price. One of the factors that determine the success of aquaculture is the availability of adequate food, both quantity and quality. There are several alternative feed ingredients that can be used in the preparation of feed. One of these feed ingredients is azolla flour made from Azolla sp. plant. Azolla sp. plant contains large amount of protein up to 28,12% of its dried weight. Selection of the base material feed using Azolla sp. based on the research results Handajani (2000) which declare that the protein content Azolla sp. which is quite high, namely 28.12% dry weight. The addition of Azolla sp. in catfish feed formulation is expected to improve retention of energy and lower feed conversion ratio. The purpose of this study was to determine the addition of Azolla sp. in feed formulations affect the retention of energy and feed conversion ratio catfish. This research was conducted in July-August in the Faculty of Fisheries and Marine University Airlangga. Research method used in the study was an experimental method with complete random planning. It included five treatments and four repetitions. Treatments that were used included azolla flour inclusion 0%, 5%, 10%, 15% and 20% at the formulated feed. Data analysis that was used included statistic and descriptive. The result of the research shows that energy retention among treatments does not have significant difference. On the other hand, the feed conversion ratio also does not have significant difference. It can be concluded that Azolla sp. inclusion in the catfish feed formulation affects nothing to energy retention and feed conversion ratio.  Keyword : Azolla sp., Clarias sp., Energy Retentiom, Feed Convertion Ratio

A trial was carried out to evaluate the effect of replacing wheat offal with rumen content on the growth performance of broiler chickens. A total of one hundred and fifty (150), one day-old broiler chicks were randomly allotted to five (5) dietary treatments containing 0, 5, 10% inclusion levels of sundried rumen content and 5 and 10% inclusion levels of roasted rumen content as a replacement to wheat offal. Each treatment was replicated three times with five (5) birds per replicate in a completely randomized design experiment. The trial lasted for eight (8) weeks. The results showed that there were no significant differences in the final weights, daily feed intake, daily weight gain and feed conversion ratio at the starter phase and finisher phases. Furthermore, no significant differences in the final weight (1346.60-1508.50g), daily feed intake (83.57-100.00g), and daily weight gain (36.43-39.53g), and were observed for the overall performance. However, there was a significant difference (P<0.05) in the feed conversion ratio with the highest being 2.69g and the lowest 2.33g in the overall performance. From these findings, it could be concluded that rumen content could replace wheat offal without any detrimental effect on the performance of broiler chickens.

Carcass Parameters

A study was carried out to evaluate growth performance and carcass characteristics of broiler birds fed with varying level of choline inclusion in their diets; T1 (control), T2 (10g/10kg) and T3 (20g/10kg). A total of 225 marshall broiler chicks were randomly divided into three (3) treatment group of 75 birds each. Each group was divided into five (5) replicates of fifteen (15) birds each laid in a completely randomized design. Feed and water was supplied ad-libitum and the experiment lasted for 49 days. The total feed intake (1316.75-14442.18) (24437.13-31999.76) for starter and finisher respectively, body weight gain (6227.30-8241.20) (10956.64-14182.96) for starter and finisher respectively, feed conversion ratio (1.73-2.26) (2.21-2.48) for starter and finisher respectively. Many (thigh, wings, back) of the carcass parameters measured were not significantly (p>0.05) affected by the treatments but significant difference (p<0.05) was observed in drum stick, breast and neck.  However, significant difference (p<0.05) was also observed in gizzard, liver and bile, heart, lungs, legs and head. There was significant difference (p<0.05) in primal cuts per live weight, primal cuts per dressed weight, organs per live weight and organs per dressed weight. In view of the results obtained, it can be concluded that treatment two (10g/10kg) performed better in terms of total body weight (TBW) and feed conversion ratio (FCR). Also in the carcass characteristics, treatment two performed better in terms of breast yield, drumstick, percentage of primal cuts from live weight (P/LW) and percentage of primal cuts from dressed weight.
