The beef heifers performance from eight to twelve months of age was evaluated in exclusive Italian ryegrass (Lolium multiflorum Lam.) pasture, ryegrass plus red clover (Trifolium pratense) LE 116 or in ryegrass pasture receiving supplement in proportion of 1% BW. The continuous grazing method with variable stocking rate was used. The supplement used was a commercial ration, with 17% of crude protein, 23.6% of neutral detergent fiber and 59.6% of total digestible nutrients. The means values of forage mass and […]

The carcass characteristics, yields and linear measurements of 24 non-castrated non defined breed lambs (SPDR) with 4.8 ± 0.8 months of age and mean initial live weight of 20.45 ± 3.25 were evaluated. The animals were kept in individual stalls and fed with diets containing 0, 10, 20 and 30% of babassu meal. A block randomized design, with six replicates and four treatments was used. A linear decreasing effect of the babassu meal on the empty-body-weight, live weight at slaughter, […]

With the objective of evaluating the relative development of live weight (LW) components, commercial meat cuts and carcass tissues, 40 Saanen male kids were used. These animals were slaughtered when they reached 5.0, 12.5, 20.0, 27.5 and 35.0 kg of LW. The carcass was sectioned as follows: shoulder, neck, 1st to 5th rip, 6th to 13th rip, brisket, chump and leg. The leg was dissected into bones, muscle and fat. An allometric equation was used Y=aXb for relative development estimation. […]

This experiment evaluated the plant and stem dry matter (DM) content, plant, stem and grain DM productivity of corn cultivars harvested in different maturity stages. A randomized block design, with a 8 × 6 × 2 factorial scheme, composed of eight harvesting times, six corn cultivars and two evaluation harvests (2001/2002 and 2002/2003) was used. Cultivars CO 32, AG 5011, P 3041, DKB 333B, AG 1051 and Z 8550 were harvested when reaching 50% of male flowering, 15 days after […]

The objective of this trial was to evaluate the nutritional value, fermentation profile and dry matter losses of Palisadegrass silages ensiled with either dried citrus pulp, soybean hulls, chemical or microbial additives. The trial was carried out in a completely randomized experimental design and in a factorial arrangement (3 × 5), with three dry matter levels (wet forage or forage ensiled with pelleted citrus pulp or pelleted soybean hulls) and five additives (without or with the presence of bacterial inoculants […]

The profile of beef meat consumers was analyzed, as well as the consumption of certificated meat, with the objective of obtaining data on the importance the of certification value at the purchasing occasion. The aim of this study was to evaluate the beef meat consumers awareness regarding the meat certification and how much they are willing to pay for this process. The data survey was carried out in only one supermarket chain from the city of Porto Alegre – RS, […]

This study was conducted to evaluate the effect of the supplementation of enzymatic complexes on the performance and carcass characteristics of broiler chickens from both sexes. Five diets were evaluated: positive control diet based on corn and soybean meal with meat and bone meal without enzyme; negative control diet formulated with 3% less of metabolizable energy; negative control + 0.05% of complex A (600 U/g of xylanase, 8000 U/g of amylase and 800 U/g of protease); negative control + 0.04% […]

The aim of this study was to evaluate the influence of body condition score (BCS) on reproductive performance of beef cows before and after calving and to evaluate the calving probability using body condition score and weight variation during critical periods of the cow reproductive cycle. From 2001 to 2005, the body condition score was recorded in 248 multiparous cows raised in native pastures, submitted to different supplementation treatments (mineral mixture only – control; dry supplement; liquid supplement and liquid […]

To evaluate the effect of probiotic (Lactobacillus sp.) associated with different crude protein (CP) levels on performance, CP nutritional requirements, carcass and cut yields of meat quails, a total of 2304 meat quails were distributed in a 2 × 4 factorial design (with and without probiotic and four CP levels – 15, 20, 25 and 30%), with two replications per treatment, repeated twice in time (two experimental periods), totalizing 32 experimental units. The addition of probiotic decreased the feed intake […]

With the objective to evaluate available phosphorus levels in diets for swine genetically selected for meat deposition, sixty commercial hybrid pigs were used, being 30 castrate males and 30 females, with initial weight of 15.00 ± 0.41 kg, distributed in a completely randomized experimental design, with six treatments, five replications and two animals (1 male and 1 female) per experimental unit. The treatments were composed of a basal diet and other five diets obtained through basal diet supplementation with dicalcium […]
