“…The improvement in daily weight gain achieved with FCF, especially in lambs with low BtW could be attributed to increased total feed intake as was evident with improvements in feed conversion ratio. The results on fattening of lambs in the present study were within the normal range (Olfaz et al, 2005;Sen et al, 2011;Sirin et al, 2011).…”

To determine effects of birth weight (BtW) and feeding system on fattening performance and behavioural responses of lambs, after birth 28 Karayaka male lambs were divided into two BtW groups, namely a low BtW (4.1±0.06 kg) and high BtW (5.0±0.09 kg). After weaning (90 days of age), seven lambs in each of these groups were fed individually ad libitum with total mixed ratio (TMR), consisted of 80% of a compound feed and 20% of roughage based on a dry matter basis (140 g crude protein and 2550 kcal ME/kg) and the other seven lambs were fed on the same ingredients as that of TMR but each ingredient was put in separate troughs (free choice feeding, FCF). Therefore the lambs were distributed into four groups according to 2 (low vs high BtW) × 2 (TMR vs FCF) factorial design. Live weight gains and intakes of dry matter, feedstuffs and nutrients of the lambs were affected by the FCF, but not by the BtW and their interaction. The daily weight gain (P<0.01), intakes of soybean meal and corn (P<0.01), dry matter (P<0.05), protein and energy (P<0.01) of FCF-fed lambs were higher than those of TMRfed lambs. FCF-fed lambs consumed less alfalfa hay, wheat bran and barley than TMR-fed lambs (P<0.01). The FCF increased rumination (P<0.01) and tend to rest more (P<0.05) compared to the TMR. The study suggests that FCF system can assist in enhancing the live weight gain by promoting the protein and energy intakes and by improving the welfare of lambs.

ResumoEsta pesquisa foi conduzida com o objetivo de se avaliar a utilização dos resíduos de abacaxi (Ananas comosus L.), banana (Musa sp.), manga (Mangifera indica) e maracujá (Passiflora ssp.) na alimentação de cordeiros confinados, sobre desempenho produtivo, rendimento de carcaça e características qualitativas e quantitativas da carne confinados. Foram utilizados vinte e cinco ovinos mestiços com a Raça Santa Inês e sem raça definida, distribuída em cinco tratamentos. Os tratamentos foram constituídos pela substituição de 75% da silagem de sorgo pelos respectivos coprodutos, sendo que no tratamento controle o volumoso foi composto apenas silagem de sorgo. As dietas tiveram uma relação de volumoso: concentrado de 40:60 em relação à matéria seca (MS) sendo isoprotéicas e isoenergéticas. Os animais foram abatidos aos 32 quilos de peso vivo. Antes do abate obtiveram-se as medidas biométricas, e logo após o mesmo, efetuou-se o peso de carcaça quente e as medidas morfométricas. Após 24 horas em câmara frigorífica à temperatura de 4 ºC, obteve-se o peso de carcaça fria e o cálculo do rendimento. A meia-carcaça esquerda foi dividida em cinco cortes: pescoço, paleta, pernil, costela e lombo, efetuandose o cálculo de rendimento dos cortes. As análises de qualidade de carne tais como pH, cor (L, a, b, croma e H o ), perda de peso por cozimento, capacidade de retenção de água e força de cisalhamento foram realizadas em amostras do músculo Longissimus dorsi. O experimento foi conduzido em delineamento inteiramente casualizado. Para a análise de variância e o teste de Tukey para comparação das médias foi utilizado a probabilidade de 5%. Não houve efeito de dietas (P>0,05) de acordo com os parâmetros: desempenho produtivo, medidas corporais e qualidade de carne de cordeiros confinados. Também não houve efeito das dietas (P> 0,05) sobre a área de olho do lombo admitindo-se que as carcaças mantiveram padrão semelhante de musculosidade fato importante para a aceitação de mercado. Concluise que, a substituição em até 75% da silagem de sorgo por resíduos de frutas (abacaxi, banana, manga e maracujá) na alimentação de cordeiros torna-se viável por não alterar o desempenho produtivo, as medidas corporais, os rendimentos de carcaça e cortes e características da carne de cordeiros confinados.

“…Cooking loss is an indicator of meat quality; the lower the cooking loss, the better the juiciness of the meat (Ameha, 2006). Therefore, the type of cooking may have effects on nutritive values, organoleptic attributes and acceptability of meat from ruminants (Wood et al, 2003;Olfaz et al, 2005). Therefore, the study was conducted to evaluate pH value, cook loss, water holding capacity, and chemical composition of meat beef, chevon and mutton consumed in the Hawassa city of Ethiopia.…”

The study was conducted to study meat quality of beef, chevon and mutton consumed at Hawassa city in Southern Ethiopia. Purposive sampling technique was used to collect information from butcheries. From each sub cities, 15 butcheries were selected randomly for the purpose thus, a total of 45 sample butchers were used. From longissimus dorsi muscle, sample of beef, chevon and mutton were taken and analyzed for the study. The average pH value of beef, chevon and mutton was 5.6, 5.8 and 5.5, respectively. The average water holding capacity (WHC) was 23, 29 and 32%, respectively, for beef, chevon and mutton. The average cook loss of beef, chevon and mutton was 33.8, 32.5 and 29.9%, respectively. Protein content of raw, boiled and roasted beef was 16.1, 23 and 31.2% DM, respectively, while the average fat of raw, boiled and roasted beef were 5.4, 7.2 and 10% DM, respectively. Ash content of 1.2, 1.8 and 2.7% DM was found for raw, roasted and cooked beef, respectively and the average moisture of raw, boiled and roasted beef was reported as 72.7, 63.2 and 51.8%, respectively. The average value of raw, boiled and roasted protein and fat chevon was 20, 29.8, 34; 5.3, 8 and 11.4%, respectively. On the other hand, ash content was 0.9, 2 and 3. 6% DM; moisture 74.2, 60.6 and 48.2%; were found for raw, roasted and cooked chevon, respectively. For raw, roasted and cooked mutton, protein content of 19, 28.2 and 32% DM; fat 6.4, 8.1 and 11.6% DM; ash 1.1, 2.7 and 3.7% DM and moisture 72.7, 59.4 and 44.8%, respectively, were found. The results indicate that the moisture, ash, protein, fat, cooking loss and water holding capacity of the beef, chevon and mutton were almost in comparable with the results reported by various researchers in Africa.
