Item Acompanhamento e controle zootécnico do sistema de produção de pequenos ruminantes (caprinos e ovinos), do CODAI/UFRPE, localizado na região da Zona da Mata Norte, no município de São Lourenço da Mata - PE(2021-12-07) Brito, Admilson Ribeiro Toscano de; Freitas, João Antônio Gomes de; http://lattes.cnpq.br/1765326853404114; http://lattes.cnpq.br/7228033819346383The Obligatory Supervised Internship (ESO) was held at College Agricole Dom Agostinho Ikas of UFRPE, Campus-Tiúma, in the Animal Science Area, in the Nucleus de Caprinovinocultura, located in the forest Mata Norte region, in the district of Tiúma, municipality of San Lourenço of the Mata, Pernambuco, under the supervision of teacher Dr. João Antônio Gomes de Freitas and supervision of teacher Drª. Elisa Alves Vilar, with a total workload of 420 hours, in the period from 08/30/2021 to 11/16/2021. Zootechnical Monitoring and Control of the Goats and Sheep Production System were carried out, involving management of facilities; food management; reproductive management; productive management; sanitary management and disposal management. This work aimed to report the main activities related to the experiences developed during the referred internship, in the goat and sheep production nucleus of CODAI-UFRPE, in the routine of raising goats and sheep. The production nucleus, mentioned above, has a fixed squad of 22 animals; being 10 goats and 10 sheep (parents); 01 goat and 01 ram (breeders), in addition to the offspring, calving, which occur during the breeding routine. The goats are predominantly of the Anglo-Nubiana breed, while the sheep come from the Santa Ines breed. The intensive production system, with an emphasis on animal welfare, is the method adopted by the production nucleus. The installations consist of suspended bays with slatted floors. Nutritional and food management is carried out in a balanced way with elephant grass pasture (Pennisetum purpureum) and supplemented with protein and mineral concentrate. The main diseases observed and treated during this period were some bacterial diseases such as caseous lymphadenitis, food poisoning, epidermatitis and parasitic diseases such as worms. Discards are carried out following the guidelines for the genetic and productive improvement of the herd. During this period the animals showed an average weekly weight gain ranging from 250g to 350g per animal (50g/day).Item Correlações entre parâmetros obtidos por meio de ultrassonografia e na carcaça de novilhos bubalinos terminados em confinamento(2021-12-03) Vieira, Guilherme Heliodoro Pedroso; Pessoa, Ricardo Alexandre Silva; http://lattes.cnpq.br/0245806512931662; http://lattes.cnpq.br/8840572890087004In order to evaluate the correlations between measurements determined in vivo by ultrasound and in the carcass of feedlot-finished buffalo steers, the experiment was carried out in the Buffalo Culture Sector of the Animal Science Department of the Federal Rural University of Pernambuco. Twenty whole buffalo Murrah steers were used, with an initial average weight of 300 kg, collective in individual pens. Feeding was confirmed by sugarcane corrected with urea and small palm (Nopalea cochenillifera) with urea, replacing wheat bran, and ad libitum approval, at 06:00 and 18:00, allowing about 10% of the leftovers. After the 80 days, experimental measures were carried out with measurements of the ribeye area (AOLU) and subcutaneous fat thickness (EGSU) by ultrasound. Afterwards, the animals were introduced to fasting for 16 hours and slaughtered to obtain the carcass. In the cold carcass, between the 12th and 13th ribs, AOLC and EGSC were measured. The experimental design adopted was in randomized blocks with four treatments. Pearson's correlation was performed between measurements determined in vivo by ultrasound and in the carcass of Murrah steers, accepting up to a level of 5% precision. Ultrasound-measured AOLU was highly correlated with carcass-measured AOLC (0.96) and carcass compactness index (0.87) selected on carcass (P<0.001). Ultrasound-measured EGSU showed high correlation (P < 0.001) with carcass EGSC (0.94) and low but slight correlation (P < 0.05) with ICC (0.48) and AOLC (0.48) chose on the carcass. AOLU and EGSU measurements adjusted by ultrasonography can be used in the evaluation of these parameters in the carcass.Item Viabilidade econômica do confinamento de ovinos alimentados com rações contendo milho ou gérmen de milho integral extra gordo associado ou não com palma orelha de elefante mexicana(2021-07-07) Souza, Felipe Gusmão de; Soares, Luciana Felizardo Pereira; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/8726088889461065The objective of this study was to evaluate the economic viability of confinement of lambs fed diets containing corn or extrafat whole corn germ associated or not with Mexican elephant ear palm (OEM). The experiment was carried out in the Sheep Sector of the Animal Science Department at the Federal Rural University of Pernambuco. Forty Santa Inês sheep were distributed in a completely randomized design using the animals' initial weight as a covariate. The treatments consisted of diets composed of tifton-85 hay, with two energy sources (corn or corn germ) associated or not with OEM palm: Corn+hay; Corn+Palm+Hay; Germ+Hay; Germ+Palm+Hay. For economic analysis, the market prices obtained for the feed ingredients and for the live weight of the lambs were considered. In possession of the cost of each ration and their dry matter consumption, the technical, zootechnical and economic indicators were analyzed. The Germ+Palm+Hay treatment presented the lowest cost value for 1 kg of dry matter. Tifton-85 hay and soybean meal had higher average market values than the other ingredients that made up the feed. The Germ+Palm+Hay treatment provided better productive and economic performance.
