“…Goats are among the major economically important livestock species in the Eastern Cape Province of South Africa (Bakare and Chimonyo 2011). In 2009, there were about 2.3 million goats in the province, which contributes about 37% of the goat population in the country (Bakare and Chimonyo 2011).…”

“…Despite, the nutritive value M. oleifera leaves, its use as a livestock supplementary feed to improve the growth and carcass characteristics of indigenous goats, such as Xhosa lop-eared goats, in South Africa is unknown, and there are a limited number of studies done worldwide (Murro et al 2003;Mendieta-Araica et al 2011). Crossbred Xhosa lop-eared goats are one of the most kept goat breeds in the Eastern Cape Province of South Africa (Bakare and Chimonyo 2011). It is believed that Xhosa lop-eared goats were used to develop the modern improved Boer goat and other big-framed genotypes (Bakare and Chimonyo 2011).…”

The objective of the study was to determine the effect of supplementing Moringa oleifera leaves (MOL) on growth performance, carcass and non-carcass characteristics of crossbred Xhosa lop-eared goats. A total of 24 castrated goats aged 8 months, with a mean initial weight of 15.1 ± 2.3 kg, were randomly divided into three diet groups with eight goats in each. The duration of the trial was 60 days. All goats received a basal diet of grass hay (GH) ad libitum and wheat bran (200 g/day each). The MOL and sunflower cake (SC) groups were fed additional 200 g of dried M. oleifera leaves and 170 g of SC, respectively. The third group (GH) did not receive any additional ration. The crude protein of MOL (23.75%) and SC (23.27%) were higher (P < 0.05) than that of the GH diet (14.08%). The attained average daily weight gain for goats fed MOL, SC and GH were 103.3, 101.3 and 43.3 g, respectively (P < 0.05). Higher (P < 0.05) feed intakes observed were in SC (491.5 g) and MOL (490.75 g) compared with GH (404.5 g). The hot carcass weight was higher (P < 0.05) for SC (10.48 kg) and MOL (10.34 kg) than for the GH group (8.59 kg). The dressing percentage in SC (55.8%) and MOL (55.1%) were higher (P < 0.05) than that of the GH (52.9%). The growth performance and carcass characteristics of SC and MOL goats were not different. Feeding MOL or SC improved the growth performance and carcass characteristics of goats in an almost similar way, which indicates that M. oleifera could be used as an alternative protein supplement in goats.

“…Goat meat (chevon) is an important protein source for human beings throughout the world, especially in developing countries (Ding et al, 2010;Bakare & Chimonyo, 2011). However, undernourished goats tend to produce poor quality meat (Mushi et al, 2009), which is attributed to poor nutrition and genotype (Madruga et al, 2008).…”

“…In South Africa over 50% of goats are reared under the communal farming system, in which there is indiscriminate crossbreeding (Rumosa Gwaze et al, 2009), and the crossbred Xhosa lop-eared goat is one such example. Crossbred Xhosa lop-eared goats are found in considerable numbers in communal areas (Rumosa Gwaze et al, 2009;Bakare & Chimonyo, 2011). They are large framed goats with the potential to increase meat supply owing to higher meat yield and twin kidding ability.…”

The objective of this study was to determine the physico-chemical characteristics and consumer sensory scores of chevon from crossbred Xhosa lop-eared goats supplemented with Moringa oleifera leaf meal (MOL). Twenty-four goats, aged 8 months, were divided into three groups with eight goats in each. All three groups were fed a basal diet of grass hay (GH) ad libitum and wheat bran at 200 g/head/day. In addition to the basal diet, the MOL and sunflower seed cake (SC) groups were fed 200 g dried M. oleifera leaf meal and 170 g sunflower seed cake, which contained 238 g and 233 g crude protein/kg, respectively, with GH having 141 g. Diet influenced chevon colour. Chevon from MOL-and SC-fed goats had higher values for lightness (L*) 24 h post mortem. The redness (a*) values of chevon 24 hours post mortem were significantly higher in MOL supplemented goats. Warner Bratzler shear force (WBSF) values of chevon from SC (30.1 N) and MOL (29.8 N) were lower than those for meat from GH diet (32.6 N). Chevon from goats fed GH diet had significantly higher cooking losses (29.5%) than that from the MOL (25.4%) and SC (25.6%) fed groups. Diet influenced the consumer sensory scores of chevon from goats supplemented with MOL, which had higher first bite, aroma, flavour and juiciness scores. Supplementing crossbred Xhosa lop-eared goats with an MOL diet produced chevon with the highest physico-chemical characteristics and consumer sensory scores. ______________________________________________________________________________________

Human‐centered, active‐learning approaches can help students develop core competencies in biology and other STEM fields, including the ability to conduct research, use quantitative reasoning, communicate across disciplinary boundaries, and connect science education to pressing social and environmental challenges. Promising approaches for incorporating active learning into biology courses include the use of course‐based research, community engagement, and international experiences. Disruption to higher education due to the COVID‐19 pandemic made each of these approaches more challenging or impossible to execute. Here, we describe a scalable course‐based undergraduate research experience (CURE) for an animal behavior course that integrates research and community engagement in a remote international experience. Students in courses at two U.S. universities worked with community partners to analyze the behavior of African goats grazing near informal settlements in Western Cape, South Africa. Partners established a relationship with goat herders, and then created 2‐min videos of individual goats that differed in criteria (goat sex and time of day) specified by students. Students worked in small groups to choose dependent variables, and then compared goat behavior across criteria using a factorial design. In postcourse surveys, students from both universities indicated overall enthusiasm for the experience. In general, students indicated that the laboratory provided them with “somewhat more” of a research‐based experience compared with biology laboratories they had taken of similar length, and “somewhat more” to “much more” of a community‐engagement and international experience. Educational benefits were complemented by the fact that international educational partners facing economic hardship due to the pandemic received payment for services. Future iterations of the CURE can focus on goat behavior differences across ecological conditions to help herders increase production in the face of continued environmental and social challenges. More generally, applying the structure of this CURE could facilitate mutually beneficial collaborations with residents of under‐resourced areas around the world.
