PREDICTION OF DAILY GAIN, BACKFAT THICKNESS AND FEED CONVERSION RATIO AMONG CROSSBRED TERMINAL SIRES BETWEEN PUREBRED DUROC, PIETRAIN, AND LANDRACE BY CBE 4.0 SOFTWARE

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

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.

Sixteen blocks of eight littermate pigs were weaned at 3 weeks of age and each divided into four groups. Various levels of nutrition were applied to the pigs so that the four groups reached 20 kg. at 59, 68, 80 and 91 days of age, respectively.Only small differences were observed between groups in feed conversion ratio to 20 kg.; however, Group 4 required more feed per kg. gain than the three other groups.During the second period (20–90 kg.) the pigs in each group were divided into two sub-groups, which were on a high and a low plane of nutrition respectively. In both sub-groups the type of feeding before 20 kg. influenced the average daily gain and feed conversion ratio. The older the pigs were at 20 kg. the higher the daily gain and the lower the feed conversion ratio in the following period. There was an increase in daily feed intake with increased age at 20 kg. for pigs fed ad lib. during the second period.An increase in age at 20 kg. caused a significant decrease in thickness of backfat, a greater area of eye muscle and a smaller area of fat overlying muscle. For pigs fed ad lib. the area of eye muscle was significantly increased by a higher age at 20 kg. live-weight.

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.

Effect Of Age

The study was conducted with the objectives to understand the effect of age of native Pabna bulls on feed conversion ratio (FCR), digestibility and carcass yield characteristics. Fifteen Pabna bulls having five in each age groups of 6 to12, 13 to 24 and 25 to 36 months were fed ad libitum mix silages of Splendida (Setaria splendida) and Andrpogan (Andropogon gyunus) grasses (1:1 fresh) and supplemented with a concentrate mixture at 1% of live weight (LW) for a period of 72 days. With the increase of age, and subsequently LW (initial LW: 98.2, 182.6 and 288 kg, respectively), there was significant decrease in dry matter (DM) intake as % LW (<0.05; 2.94, 2.61 and 2.36, respectively) and increased daily gain (<0.01; 294, 519 and 597 g/d, respectively). However, the feed conversion ratio (FCR) (>0.05; 10.88, 10.10 and 12.24, respectively) and DM digestibility (>0.05; 51.0, 48.1 and 49.1 %, respectively) of bulls were remained unchanged. In case of carcass yield characteristics, significantly lower yield grade (<0.01; 1.79, 1.27 and 0.20, respectively) of bulls of 25 to 36 years produced higher closely trimmed boneless retail cuts (CTBRC) (<0.01; 50.47, 51.64 and 54.14 %, respectively), retail cut (<0.01; 76.14, 78.55 and 83.48 %, respectively) and meat quality index (MQI) (<0.01; 67.28, 67.89 and 69.07, respectively) compared to younger bulls. It may, therefore, be recommended that beef cattle farming with native Pabna bulls of 24 to 36 months will give more daily LW gain and produce more CTBRC at a similar FCR compared to younger ones.Bang.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.

Abstract Improved genetics in commercial pig production have resulted in larger litter sizes. However this has increased the prevalence of compromised pigs exhibiting inferior birthweights, weaning weights, and lifetime performance. This study aimed to determine the effects of increased sow lactation feed intake on growth of low and average birthweight piglets until 10 wk of age. Low (Low BW; <1 kg) and average (Av BW; 1.3–1.7 kg) birthweight animals were reared in uniformly weighted litters comprising 14 piglets on a foster mother offered either a low (Low FA; max 7.5 kg/d) or high (High FA; max 11 kg/d) feed allowance over a 28- ± 1-d lactation. Piglet performance was monitored from birth until 10 wk of age. Sows offered a High FA consumed 42.4 kg more feed on average than those offered Low FA, resulting in a greater derived milk yield (P < 0.05). Animals of Av BW remained heavier than Low BW pigs throughout the trial (P < 0.05). Piglets reared by High FA sows were heavier at weeks 3, 4, 5, and 7 (P < 0.05) but not week 10 (P > 0.05). Growth rate of piglets relative to their birthweight was significantly greater for Low BW piglets than those of Av BW during lactation (P < 0.001). Piglets reared by sows offered a High FA expressed greater relative growth preweaning (P < 0.05); however, postweaning relative growth for piglets reared on sows offered a Low FA was greater (P < 0.05) suggesting compensatory growth. Neither birthweight nor sow feed allowance significantly affected preweaning mortality (P > 0.05). However, Low BW animals on sows with a High FA recorded half the preweaning mortality of Low BW pigs on sows with a Low FA. During week 1 of lactation, Av BW litters recorded a greater total suckling duration compared to Low BW litters (P < 0.05) but there was no difference in suckling frequency (P > 0.05). During week 3 of lactation, High FA litters displayed a significantly lower suckling frequency (P < 0.05) yet a greater total suckling duration (P < 0.001). Average daily gain was greater for Av BW pigs during weeks 4–7 (P < 0.001) but no difference was recorded between weeks 7 and 10 (P > 0.05). Average daily feed intake was greater for Av BW pigs throughout the nursery period (P < 0.05) but feed–conversion ratio did not differ compared to Low BW pens (P>0.05). In conclusion, offering sows a High FA increased weaning weight of all animals; however, birthweight was the major determinant of postweaning performance.

The objective of the study was to evaluate the effects of expanded diets on growth performance, meat quality, and carcass characteristics in finishing pigs. A total of 80 finishing pigs [(Landrace × Yorkshire) × Duroc] were randomly allotted to two dietary treatments: 1) unexpanded corn-soybean meal diets; 2) expanded corn-soybean meal diets. Each treatment consisted of ten replicate pens with four pigs (2 gilts and 2 barrows) per pen. There were no differences in daily feed intake and daily gain throughout the experiment (P less than 0.05). However, expanded diets decreased feed conversion ratio compared with unexpanded diets (P less than 0.05). Expanded diets had no effect on carcass characteristics and meat quality with the exception of increased sensory evaluation (color) of meat compared with unexpanded diets (P less than 0.05). In conclusion, expanded diets can improve feed conversion ratio but have no effect on daily gain and daily feed intake and sensory evaluation of meat color.
