SAANEN CARCASS QUANTITATIVE AND Longissimus dorsi QUALITATIVE CHARACTERISTICS OF FEEDING WITH PROTECTED FAT

Twenty-eight uncastrated male Saanen goat kids, on a feedlot, with an average slaughter weight of 28 kg were used to evaluate the effects of feeding goat kids with metabolizable energy levels by the addition of protected fat to the diet. The effects on the quantitative characteristics of the carcass and qualitative characteristics of the loin were assessed. The animals were randomly distributed into one of the four groups: one control group (without protected fat) was fed a diet containing 2.5 Mcal of metabolizable energy/kg dry matter (ME/kg DM). The other three groups were fed diets containing 2.6, 2.7 or 2.8 Mcal of ME/kgDM, using protected fat to increase the energy levels. The carcass quantitative characteristics were not influenced by the diets; however, a reduction was observed on the days of the feedlot and slaughter age for the animals fed protected fat diets. The short length and fat thickness in the loin has improved from diets with protected fat addition. The muscle, fat and bone proportions and the chemical composition of the Longissimus dorsi were similar between the diets. There was an increase in the fatty acid profiles of the polyunsaturated fatty acids linoleic and linolenic and improvements in the total omega-3 levels and the ratios of omega-6: omega-3. The protected fat can be used to feed Saanen kid goats as an alternative, increasing the energetic density of the diets up to 2.8 Mcal of ME/kg DM with improvements on the omega-3 quantity. And it can also be used to increase the ratio of omega-6:omega-3 in the Longissimus dorsi

CARNE BOVINA COM QUALIDADE: UMA REVISÃO / BEEF MEAT QUALITY: A REVIEW

A diferenciação dos alimentos proporciona um produto de melhor qualidade ao consumidor final. O aumento da exigência dos consumidores pela qualidade dos produtos alimentares força para que as organizações desenvolvam instrumentos com maior eficiência na segurança, diferenciação e na agregação de valor aos seus produtos. A rastreabilidade proporciona ao consumidor, através de legislação comunitária, a garantia de um produto que está sendo rastreado em todas as fases do processo produtivo, permitindo também voltar às origens, fornecendo informações úteis para corrigir e aperfeiçoar as cadeias. Objetivou-se com esta revisão abordar a produção de carne com qualidade à consumidores exigentes.</p

Desempenho e características de carcaça de cabritos da raça Saanen recebendo rações com farelo de glúten de milho e/ou farelo de soja - DOI: 10.4025/actascianimsci.v25i2.2012

This research was carried out in Iguatemi Experimental Farm, Universidade Estadual de Maringá, Maringá (State University of Maringá), state of Paraná, Brazil, to study the performance of 30 Saanen (±17kg) kids, 75-day-old males and females, in feedlot for 70 days. The rations were adjusted with corn gluten meal and/or soybean meal, with 12.5% CP and 2.56 Mcal ME/kg of DM. The dry matter intake (kg/day), daily average gain and feed conversion ratio presented the best responses on soybean meal treatment. The variables of live weight in the origin and to the slaughter, loss weight in the origin, fat thickness, cooling loss, weight of the middle carcass, commercial carcass yield and biological carcass yield, carcass compactness, ham compactness, yield for ham, pallete, loin, rib, uncovered rib and neck did not differ (p>0.05) between the [email protected] RESUMO. O trabalho foi conduzido na Fazenda Experimental de Iguatemi, UEM/Maringá, Estado do Paraná, com o objetivo de avaliar o desempenho de 30 cabritos (±17kg), sendo machos e fêmeas com 75 dias de idade, confinados durante 70 dias, recebendo rações com diferentes fontes de proteína (farelo de glúten de milho e/ou farelo de soja), apresentando 12,5% de PB e 2,56 Mcal de EM/kg de MS. A ingestão de matéria seca em kg/dia, o ganho médio diário e a conversão alimentar apresentaram melhores respostas para o tratamento com farelo de soja. Ao término do experimento, os machos inteiros foram abatidos para avaliação de carcaça. As variáveis de peso vivo na origem e no abate, perda de peso na origem, espessura de gordura, perda por resfriamento, peso da meia carcaça, rendimentos do pernil, paleta, lombo, costela, costela descoberta e pescoço não diferiram (p >0,05) entre os tratamentos

Effect of whole oilseeds feeding on performance and nutritive values of diets of young growing saanen goats

Twenty-eight Saanen goat kids (16 non-castrated males and 12 females; 14.38±1.60 kg) were used to evaluate the performance and nutritional value of diets. Animals were randomly allotted into a 4x2 (diets x gender) factorial arrangement. Treatments consisted of four different total mixed diets composed of oat hay, soybean meal, mineral supplement, and/or oilseeds replacing ground corn (on dry matter basis), as follows: 1) control (without oilseeds), 2) diet containing 7.9% flaxseed, 3) diet with 7.3% sunflower, and 4) diet containing 8.0% canola. Dry matter intake was higher for animals receiving control diet. Gender did not influence dry matter and nutrient intake. Oilseeds did not affect the average daily gain (ADG) and feed conversion (FC). Flaxseed diet showed more days in feedlot. Males showed better means of ADG, FC and days in feedlot. Diets containing oilseeds had higher values for ether extract digestibility and lower total carbohydrates than the control diet. The energetic value of diets did not alter. The inclusion of flaxseed, sunflower or canola in diets of Saanen goat kids in place (8% on a DM basis) corn, does not improve the performance, however these oilseeds may be used without changing the nutritional value of diets
