title: INFLUENCE OF CO2 LEVELS AND TYPE OF INCUBATOR ON THE PERFORMANCE OF BROILERS

description: Abstract The aim of this work was to assess single and multiple-stage incubators and different CO2 levels over performance, number and diameter of muscle fibers, cardiac morphometry and carcass yield of broilers. Two thousand five hundred and twenty fertile eggs were randomly allocated and distributed into four different CO2 levels (4,000, 6,000, 8,000 and 10,000ppm) during the first ten days of incubation. After hatchling, 1,050 male chicks were placed into an experimental barn following the design used in the hatchery. Induced hypercapnia during the first ten days affected weight gain and feed conversion ratio of one-week-old chicks. However, these aspects did not last until the end of the rearing period. There was no effect of either hatchers or hypercapnia on number and diameter of muscle fibers and cardiac morphometry. Higher thigh yield was noted in the birds from single-stage incubators up to 6,000ppm of CO2. This fact is explained through higher vascularization caused by premature hypercapnia.

title: ZOOTECHNICAL PERFORMANCE OF NILE TILAPIA (Oreochromis niloticus) JUVENILE FED WITH PROBIOTIC CEPAS AND SUBMETIDS A HEALTH CHALLENGE

description: Abstract: The appearance of diseases caused by stress during the cultivation of juveniles have become rather common due to the intensification of the production systems, causing high mortality and economic loss to the grower. Due to this context, the probiotics (which are a group of live microorganisms) are being employed due to their capacity of establishing and multiplying in the host’s intestine and promote equilibrium to the microbiota contributing with the sanity and performance of fish, especially in the first weeks of life. Thus, this work had as objective to evaluate the development of juvenile of Nile tilapia fed with probiotic strains and subjected to sanitary challenge. 180 juvenile were experimented, distributed in a completely randomized design with three treatments, four replications and 15 fishes as experimental unit. The treatments were: T1 - fish cultivated in clean water without the use of probiotics; T2 - fish cultivated in water under challenge and without the use of probiotics; DP - fish cultivated in water under challenge with the use of probiotics. There was no significant effect (P&gt;0.05) in the parameters of zootechnical performance, feeding consumption and survival rate. The use of probiotics in the feeding was not able provide improvements in the performance, feeding consumption and survival of juvenile Nile tilapia in the period of 30 days of cultivation.

title: PRODUCTIVE PERFORMANCE OF PRE-WEANED CALVES REARED IN THE PANTANAL

description: Abstract Early weaning (EW) has been adopted in cattle breeding farms in Pantanal as a strategy to increase the rate of pregnancy in cows. The primary income of these properties is the production of beef calves, and the price of these animals depends on their weight. Therefore, the calves subjected to EW should present weight similar to or higher than those of calves subjected to conventional weaning (CW). This study aimed to evaluate the productive performance of pure (Nellore) calves and crossbred (Nellore/Angus) calves reared in the Pantanal and subjected to either EW or CW. After EW, the calves were supplemented with concentrate at 1 kg/animal/day (low-energy diet) or 1% of live weight (high-energy diet). The weights adjusted to 300 days of age were higher for EW calves fed the high-energy diet (p&lt;0.01) in both genetic groups. No significant differences were observed in the weight of EW animals fed the low-energy diet and CW animals (p&gt;0.01), and animal weight was 241.17 and 236.27 kg in crossbred calves and 184.44 and 189.78 in Nellore calves, respectively. The EW adopted in this experimental model did not affect the productive performance of calves raised in the Pantanal.

title: PERFORMANCE, CARCASS AND MEAT CHARACTERISTICS OF LAMBS IN FEEDLOT FED DIETS WITH INCREASING LEVELS OF FRESH ORANGE PULP REPLACING CORN

description: Abstract The objective of this research was to evaluate the performance, the quantitative and qualitative carcass and meat characteristics of finished lambs with different levels of fresh orange pulp replacing corn. Thirty-two whole males of Texel breed were used, with a mean initial weight of 16 ± 2.5 kg. The animals were distributed in a completely randomized design in four experimental treatments, with eight replicates each. The treatments were four levels of orange pulp (0, 33, 66 and 100%) replacing corn on dry matter. The animals were slaughtered when they reached 32.5 kg of live weight. Average daily weight gain (188 g per day), total weight gain (16 kg) and slaughter weight (32.5 kg) were similar among treatments. The loin eye area and subcutaneous fat thickness decreased linearly as a function of the orange pulp inclusion levels in the diet. The performance and carcass characteristics were not altered by the partial or total replacement of the corn with orange pulp. However, the total replacement of corn with orange pulp reduced loin eye area by 32% and subcutaneous fat thickness by 35%.

title: PRODUCTION AND NUTRITIVE VALUE OF CANARANA ERECTA LISA (Echinocloa piramidalis Lam.) IN RESPONSE TO HARVEST INTERVALS

description: Abstract The objective of this study was to compare and explain the variations in the production and nutritive value of canarana erecta lisa grass (Echinocloa pyramidalis Lam.) at different harvest intervals. The treatments corresponded to the cut intervals of 20, 27, 34, 41, 48, 55, 62, and 69 days. The experimental design was a randomized complete block design with three replications. Each experimental unit had 6m2 (3m ×2m). The variables studied included forage production, canopy height, and nutritive value o harvested forage. Forage production varied from 11517 to 12324 kg ha-1; Plant heights from 48.8 to 234 cm; Neutral detergent fiber (NDF) from 68.8% to 71.13%; Acid detergent fiber (ADF) from 36.20% to 44.15%; Crude protein (CP) from 11.43% to 5.85% and in “in vitro” dry matter digestibility (IVDMD) from 63.30% to 47.42%. These values indicated that the nutritive value of canarana erecta lisa was reduced at longer harvest intervals. It is recommended to harvest the grass at 35 days of regrowth favoring productivity, nutritive value and forage digestibility.

title: USE OF VIRGINIAMYCIN AND SALINOMYCIN IN THE DIET OF BEEF CATTLE REARED UNDER GRAZING DURING THE RAINY SEASON: PERFORMANCE AND RUMINAL METABOLISM

description: Abstract The rumen is the most studied organ with regard to the symbiotic interaction between host and microbiota in the digestive tract of ruminants. Thus, this study aimed at evaluating the effects of including virginiamycin and salinomycin to the supplement for cattle fed tropical grass diet during the rainy season. Three treatments were set: control - mineral supplement COMIGO - Cria 61-F2 (MS); virginiamycin - MS + virginiamycin (Phigrow (r)) 100 mg/animal/day; salinomycin - MS + salinomycin (Posistac(r)) 108 mg/animal/day for the experiment 1 (performance) and experiment 2 (ruminal metabolism). The control showed higher Mineral supplement intake (MSI) (P &lt;0.05), the virginiamycin had higher average daily gain (ADG) (P&gt; 0.05) and better financial efficiency. Biometric measurements showed no differences (P&gt; 0.05), suggesting a change in the ADG composition. There was no difference (P&gt; 0.05) for dry matter digestibility (DMDIS), acid detergent fiber digestibility (ADFDIS), ruminal pH and ammoniacal-N. The virginiamycin had the highest effective neutral detergent fiber (NDF) degradability (P&gt; 0.05) in the passage rates of 2 and 5%; the degradability rates were similar to control treatement and higher than that of salinomycin at the rate of 8%/hour. The virginiamycin or salinomycin can be conveyed to the MS, but do not promote significant effects on ruminal pH, ammoniacal-N, DMDIS and ADFDIS; but virginiamycin promoted greater effective degradability of NDF.

title: ALLOMETRIC GROWTH IN BRAZILIAN NATURALIZED PIGS

description: Abstract The allometric growth of male and female naturalized pig breeds (Nilo, Piau, Moura, and Monteiro) was evaluated regarding hip height, snout length, and head length using the allometric equation. Body measurements generally show later growth in relation to the snout length and earlier growth in relation to the head length and hip height. When comparing breeds of pigs, female Moura animals showed later growth of the characteristics linked to muscle (thoracic circumference, body length, and longitudinal diameter) than of head length. Nilo females showed characteristics such as shoulder length, rump length and interschiadic distance earlier than snout length. There were differences between the breed and gender in terms of development times for the different parts of the body, showing that breeding systems and use of these animals have to be specific for each breed.

title: ANDROLOGICAL POINTS CLASSIFICATION AND ANDROLOGICAL REPRODUCTIVE EVALUATION CHARACTERISTICS IN GIR BULLS CANDIDATES FOR PROGENIETEST

description: Abstract Reproductive efficiency should be evaluated in dairy farms, when they are related to reproductive problems in both female and male. Breeding is among factors that affect herd productivity and draws attention by low rates of traditional livestock breeding. The aim was to study sperm evaluation tool known as the CAP index and its correlation with the biometric and morphological analyzes of Gir bulls semen. Thirty four healthy Gir bulls (Bos taurus indicus), dairy fitness, with 17 to 31 months of age with 450 kg of body mass were used. The bulls were submitted to andrological examination (physical evaluation including testicular biometry and semen morphological analysis) follow by andrological classification by points (CAP index). Three independent collections were carried out to evaluate sperm quality per bull during the experiment period According to the CAP index, animals were classified as excellent (17%) and as very good (83%). The CAP Index correlated positively with scrotal perimeter and semen physical characteristics.

title: PERFORMANCE OF CREEP FEED LAMBS, FINISHED UNDER FEEDLOT OR Brachiaria brizantha DEFERRED PASTURE: GASTRINTESTINAL PARASITISM AND BIOECONOMIC EFFICIENCY

description: Abstract The objectives of this study were to evaluate the effect of creep feeding and drylots or semi confined raised lambs on weight gain, gastrointestinal nematodes infection and economic viability. Lambs from six lots of 30 ewes were weighed at birth and at weaning and the offspring of three lots were supplemented in private troughs and their food intake was measured. In the second phase, after weaning, lambs were divided into two finishing groups, feedlot or semi confinement considering gender, weaning weight and creep feeding. All animals were dewormed at early termination, weighed every 14 days and supplemented with 2% of body weight. Feedlot animals received sorghum silage while semi confined animals were kept at pasture on Brachiaria brizantha cv Piata. Creep feeding had effect on weight and weight gain at weaning and finishing, but favorable economic returns were only observed at termination. Pasture deferred in the semi-confinement system controlled verminosis, preventing deaths with no differences in weight and weight gain among feedlots or semi-confined lambs. Both systems were economically viable, but profit in semi confinement was 2.3 times higher than the feedlots.
