The objectives of this study was to analyze the comparative ability of animal genetic, using evaluation of production that has important economic traits including Landrace, Yorkshire, and Duroc breeds of swine. A total of 49 swine consist 15 boars and 34 gilts, with average body weight of 18.50-21.50kg were used in this research. All of samples were raised in the same pen and feeding management. This research used the experimental method of Completely Randomized Design involving three treatments of animal breeds including Landrace, Yorkshire, and Duroc breeds. The data were analyzed by using analysis of covariance procedur General Linier Model and Least Square Means test. Boars and gilts were analyzed in separated data. The result showed that the effect of breed was significantly associated for all traits, but not for boars feed intake. The overall, Yorkshire and Landrace performed better than Duroc for average daily gain, feed conversion ratio, selection index, and age at 90 kg body weight. However, Duroc boars and gilts had the thinnest backfat followed by Yorkshire and Landrace.

The objective of this work was to evaluate the effect of slaughter body weight on the quantitative characteristics of carcasses and the yield of commercial cuts of young Nellore bulls. Twenty-four non-castrated, 11-month-old, feedlot-fed Nellore bulls were distributed in a completely randomized design, in three treatments: 350 kg, 400 kg or 450 kg of body weight at slaughter (SBW). Slaughter was performed in a commercial slaughterhouse. The data were analyzed by an ANOVA followed by a Tukey test (p ? 0.05). SBW had no relationship with dry matter intake (6.05 kg/day or 75.74 g/kg BW0.75), feed efficiency (22.16) or feed conversion (4.67). Average daily gain was different depending on the SBW. Animal slaughtered at 350 kg had gained 1.17 kg/day, whereas animals slaughtered at 400 and 450 kg had gained 1.49 and 1.47 kg/day, respectively. Cold carcass weight increased with SBW (189.50, 209.33, and 242.39, respectively). Other carcass characteristics, like pH at 48 h (5.75), cold dressing carcass (52.61%), chilling losses (1.79%), fat thickness (5.54 mm), marbling (3.34 points), intramuscular fat (6.68%), longissimus muscle area (63.10 cm2) and sarcomere length (1.60 ?m), were not affected by SBW, but SBW increased cold carcass weight. The treatments had effects on the primary and commercial cut weights. However, the cut yields for the forequarter (39.84%), hindquarter (47.82%) and side-cut (12.34%), and the secondary cuts: chuck (14.38%), hump steak (1.94%), shoulder clod (16.97%), brisket point end (5.56%), neck steak (1.00%), striploin (7.77%), outside flat (5.30%), topside (9.36%), tenderloin (2.16%), flank steak (3.41%), eyeround (2.67%), rump tail (1.20%), rump eye (3.89%), shank (4.44%), knuckle (5.25%) and rump cap (1.40%), were not affected by SBW. SBW did not influence (p > 0.05) the commercial cut compositions for all cuts in the forequarter and hindquarter. Finishing young bulls in a feedlot is a strategy to produce beef with reduced feed costs. After all, the slaughter body weight (350, 400 or 450 kg) influenced the quantitative characteristics of the carcass; however, it did not affect the yield of commercial cuts from young Nellore bulls.

THE EFFECTS OF AFFERING KING GRASS (Pennisetum Purpupoides) AND CORN STOVER ON PERFORMANCE OF ONGOLE CROSSBREED COWS A research evaluating the effects of affering king grass (Pennisetum purpupoides) and corn stover as feed ingredients on performance of ongole crossbreed cows has been conducled. Two years old, of fifteen ongole crossbreed cows with ± 200 kg body weight were used in this experiment. Completely  Randomized Design with 5 treatments and 3 replications was used. The treatments were R1 = 100% king grass, R2 = 75% king grass + 25% corn stover, R3 = 50% king grass + 50% corn stover, R4 = 25% king grass + 75% corn stover and R5 = 100% corn stover. Variables measured were dry matter consumption (DMC), average daily gain (ADG) and feed conversion (FC). The average of DMC, ADG and FC were 4,64-5,97 kg/tail/day, 0,36-0,55 kg/tail/day and 10,89-13,44 respectively.  The results showed that there were significant effects (P<0,05) on DMC and ADG, however, there was no significant effect (P>0,05) on FC. Tukey test showed that DMC of cows fed R1 were significantly (P<0,05) lower compared to R5, however, there was no significant (P>0,05) difference among cows fed R3, R4 and R5. ADG of cows fed R1 was not significantly (P>0,05) different compared to R2, R3 and R4, while, cows fed R1 and R2 were Significantly (P<0,05) lower compared to R5. Based on the results on DMC, ADG and FC it can be concluded that to increase performance of crossbreed cows the portion of king grass can be affered up to 50%, on the other hand corn stover is more than 50% in the ration. Key words :     Kinggrass (Pennisetum purpupoides), corn stover, performance ongole crossbreed cows.

Noi chicken is one of the most popular native breeds in the South of Vietnam because their good meat quality and disease resistance. Therefore, although price of their products (eggs and meat) is always high, they are always preferred. However, there have not been many studies on the morphology of this breed yet. In the current study, a total of 355 Noi chickens (164 males and 191 females) at 28 days old were selected and randomly allotted to individual cages until they reached the market weight at 84 days old. During the experiment, Noi broilers were fed ad libitum a diet with 17% crude protein and 3.000 kcal/kg ME produced by GreenFeed Vietnam Joint Stock Company. Average daily gain, feed conversion ratio and some morphological dimensions were recorded at two different stages of age (28-56 and 56-84 days old). Results were demonstrated that (i) significant differences in feed intake (P=0.006), body weight (P=0.019), beak length (P=0.014), thigh length (P=0.004), shank length (P=0.003), breast diameter (P=0.000), and thigh diameter (P=0.001) were found between males and females as well as between different stages; and (ii) body weight and some dimensions will increase rapidly at the first stage. An understanding on these economic traits helps researchers and producers have a more detailed glance on developing of each part of Noi chicken at different stages of age which they are the basic scientific foundation for further studies on this breed.

This study aims to examine the different weighting and different types of commercial feeds on the growth of broiler chickens. The study was prepared based on Completely Randomized Design (RAL) of 4 x 3 and 3 replication factorial patterns. The first factor is Grouping Cut Off (600 - 1000 grams or ± 800 g, 1,100 - 1300 g or ± 1,200 grams, 1,400-1,700 or ± 1,600 grams, 1,800 - 2200 g or ± 2,000). The second factor is the type of commercial feed / ration from different factories (AB1, BP11 and P11). Parameters measured include: feed intake, drinking water consumption, body weight gain, feed conversion and final cutting weight. The results of this study indicate that the use of commercial BP-11 feed on various commercial broiler feed factors resulted in increased body weight, better feed conversion compared with AB-1 and P-1 feed types. While the cut weight factor significantly affect the consumption of feed as weight gain and cut weight. At the cut weight of 1100-1500 grams, the average feed conversion produced is the lowest that is 1.26 which indicates that this cut weight is most favorable with the smallest feed efficiency. Keywords:   cutting weight, commercial feed, growth, feed consumption, average daily gain, feed conversion, broiler chicken

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.

Background: The effects of the probiotics vary with the doses and strains used for this reason, a study was conducted over 35 days to determine the effect of live yeast supplementation in the diet of growing rabbits on growth performance and apparent nutrient digestibility.Methods: A total of 60 New Zealand and California rabbits (5 weeks old, average body weight 0.881±0.015 kg) were housed in 30 cages. They were fed with a control diet based on alfalfa and maize or barley grains and supplemented with Procreatin®7 (Saccharomyces cerevisiae CNCM I 1077) or Biosaf® SC47 (Saccharomyces cerevisiae NCYC Sc47) at three doses, namely 0, 6.4, or 12.8 ×109 CFU per kg basal diet.Result: The higher yeast concentration had a positive effect (P less than 0.01) on final body weight (BW), average daily gain (ADG) and carcass weight (CW). However, there were no significant differences in dry matter intake. As a result of this, the feed conversion ratio (FCR) decreased (P less than 0.01). Significant increases (P less than 0.05) in nutrient digestibility (DM, OM, NDF and ADF) were observed with both grains. The use of yeast in maize and barley-based diets of rabbits has positive effects on growth performance and nutrient digestibility.

This experiment was carried out with the objective of determining the macrominerals (Ca, P, Mg, K and Na) requirements of Nellore steers under grazing. Twenty four Nellore steers (371 ± 14 kg of BW and 26 mo old) were used. Four steers were slaughtered at the beginning of the experiment (reference group), serving as a reference in subsequent study. The remaining 20 animals were weighed and distributed into a completely randomized design with four supplementation levels offer: 0.0 (mineral mixture - control), 0.3, 0.6 and 0.9% of BW, with five replications. The supplements, based on ground corn, soybean meal and/or urea, were previously balanced to achieve an average daily gain of 350, 650 and 850g, respectively, for the different supplementation levels offer. The contents of macrominerals retained in the animal body were determined by regression equations of the macrominerals body content logarithm in function of the empty body weight logarithm (EBW). Net macrominerals requirements for a gain of 1kg of EBW were obtained using the equation Y'= b.10ª.Xb-1, with a and b, respectively, the intercept and the regression coefficient of the prediction equations of macrominerals in the animal body contents for each macromineral considered. The concentrations of all macrominerals, in the empty body weight and gain of the empty body weight, decreased with the increase in the body weight. Total calcium and phosphorus dietary requirements are higher than those recommended in the literature.

The objective of this work was to evaluate performance, efficiency parameters and phenotypic correlations among measurements of energy efficiency of Nellore cattle selected for post weaning weight and classified according to residual feed intake, calculated by the difference between observed and predicted intake, based on average metabolic body weight and average daily gain. Thus, animals were classified within three groups: high (> mean + 0.5 standard deviation, less efficient); medium (±0.5 standard deviation of the mean); and low (< mean - 0.5 standard deviation, more efficient) residual feed intake. No differences were observed at initial and final body weights, average daily gain and dry matter intake among groups. Animals with low residual feed intake also had greater feed efficiency, feed conversion and partial efficiency of growth and did not differ from the other animals regarding to relative growth rate and Kleiber ratio. Residual feed intake was significantly correlated to feed efficiency (-0.25), feed conversion (0.25), partial efficiency of growth (-0.37) and dry matter intake (0.16) but it did not present significant correlation with body weight (0.04), average daily gain (-0.02), relative growth rate (-0.03) and Kleiber ratio (-0.05). Significant correlations were found between feed conversion and initial body weight (0.34) and average daily gain (-0.46). Partial efficiency of growth presented significant correlation with all other efficiency parameters analyzed. Residual feed intake has high potential in productive efficiency, when compared to the other energy efficiency measurements, being independent of growth and size of the animals.

Recycled paper products were evaluated as litter material for broilers; parameters were growth performance, carcass quality, and footpad problems. One hundred sixty-eight broiler chicks were raised to market age (42 d) in an open-sided poultry house located at the Lajas Agricultural Experiment Station Small Animal Research Farm. Birds were assigned to 12 floor pens bedded with either rice hulls (RH) as control; a 50:50 mix of RH and shredded white paper (SWP); or a 50:50 mix of RH and shredded newspaper (SNP) according to a completely randomized design replicated four times. Traits measured were body weight, feed intake, feed conversion, carcass yield, breast blister score, footpad burn score, and mortality. Litter moisture percentage was assessed at 14, 28, and 42 d of age. Litter material had no influence on body weight, breast blister score, or bird mortality. However, birds raised on SWP had lower feed intake and higher body weight than those raised on RH and SNP. No significant differences in feed conversion were observed among treatments from 7 to 28 d of age. At 35 and 42 d, birds raised in SWP had significantly lower feed conversion than controls, whereas feed conversion of birds raised in SNP did not differ from that of the other treatments. No differences were found for carcass yield among treatments. At all sampling times, litter moisture percentage was significantly higher in SNP than in the control. No litter caking problems were observed in any of the treatments. Significant differences in footpad burn scores were observed among all treatments, with birds raised on SNP having higher scores (severer lesions), than those on SWP and RH.The results suggest that recycled paper products could be an excellent alternative bedding material for broilers. The use of SWP as litter appears to improve broiler performance and reduce the incidence of footpad problems.
