No significant differences (P > 0.05) between dressing percentage of broilers from the two treatments were observed. As birds grew, significant differences (P < 0.05) in LW, FI, AFI, FCR, and CFI, over a four-week period were recorded. Results of the allergen analyses indicated that soy and gluten allergens were not carried over from feed into eggs and meat of chickens fed a maize/soya bean-based diet and a maize/soya bean-based with a 15 percent whole wheat inclusion, respectively. In conclusion, a maize/soya bean-based diet and maize/soya bean-based diet with a 15 percent whole wheat inclusion that contained soy and gluten allergens, are feed sources that promote and stimulate 36-week-old LW hen and Ross 308 chicken growth.]]> Wed 12 May 2021 15:46:51 SAST ]]> Primiparous and multiparous cow behaviour of friesland, jersey and cross-bred cows around calving time and during milking https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40665 Wed 12 May 2021 14:59:24 SAST ]]> Glycolytic potential and meat quality from dorper and merino sheep slaughtered at a commercial abattoir https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40361 Wed 12 May 2021 14:37:59 SAST ]]> Determination and validation of medicinal plants used by farmers to control internal and external parasites in goats in the Eastern Cape Province, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27718 Thu 13 May 2021 07:03:47 SAST ]]> Effect of Tenebrio molitor larvae as a protein source on growth performance, carcass yield and meat quality of broiler chickens https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27944 0.05) to T3. The dressing percent of T1 was significantly different (P<0.05) from T2 and T3 which were similar to each other, with T2 having the highest dressing percentage (78, 2 percent) and T1 having the lowest DP percent (66 percent). The breasts in T2 were significantly higher and different (P<0.05) from both T1 and T3 which were similar to each other. The drumsticks in T3 were significantly different (P<0.05) from T1 while they were similar to T2 with values with T2 having highest values. After 45 minutes of slaughter, a significant difference (P<0.05) was observed in L⃰ among all treatments. In redness (a⃰), T3 was significantly different from T1 but was similar to T2 and all treatments in this study exhibited a darker red meat, with T3 muscles exhibiting darker red colour than the other treatments. Similar results were observed in yellowness (b⃰), where the breast muscles from T3 were more yellow than the other treatments. After 24 hours of slaughter, T2 L⃰ values were significantly different (P<0.05) from both T1 and T3 which were similar to each other. It was also found that the broiler chickens given diet with no T. molitor L inclusion (T1) had lower values of BW, FI, ADG and FCR throughout the experiment than those that were in T2 and T3 with 5 percent and 10 percent T. molitor L inclusion levels, respectively. However, it was also found that although broilers with 5 percent T. molitor L inclusion (T2) in their diet had high ABW and ADG than the broilers with 10 percent T. molitor L inclusion (T3), the T3 birds compared favourably to T2 birds as they required low feed intake to reach the same slaughter weight due to high FCR. It was, therefore, concluded that T. molitor L meal can be incorporated into the diets of broilers to produce heavy birds either at 5 or 10 percent. However, although 5 percent T. molitor L inclusion yields heavier carcasses, the 10 percent T. molitor L inclusion compared favourably to 5 percent inclusion since it required low feed intake to reach the same slaughter weights and there were slight differences on meat quality attributes between the two treatments.Thus T. molitor L at 10 percent inclusion levels was the best inclusion level to enhance broiler growth performance, carcass yield, meat yield and meat quality.]]> Thu 13 May 2021 04:45:31 SAST ]]> Microbiological analyses of beef slaughtering process and meat safety knowledge of handlers at selected high and low thoughput abattoirs https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27712 Thu 13 May 2021 03:29:07 SAST ]]>
