“…The Boer goat breed is an important meat breed in South Africa which is well known for their good quality meat and rough-fed resistance as well as strong adaptability ( Chong et al, 2019 ). However, little information on the effects of thermal stress on the immune function of this particular breed was available.…”

IntroductionThis study was conducted to evaluate the effects of fermented feed of Pennisetum giganteum (P. giganteum) on growth performance, oxidative stress, immunity and gastrointestinal microflora of Boer goats under thermal stress.MethodsThe study was conducted during 45 days using twenty 2 months Boer goats. The goats were randomly allocated into two groups: NPG (n = 10; normal P. giganteum) and FPG (n = 10; fermented feed of P. giganteum), and the ratio of concentrates to roughage was 3:2. Both groups of animals were kept in sheds and exposed to summer thermal stress from 10:00 h to 18:00 h (temperature and humidity index, THI > 78). At the end of the study, the animals were slaughtered and assessed for various characteristics.ResultsThe findings from the study revealed that FPG-feeding significantly increased (p < 0.05) average daily gain (ADG, 48.18 g) and carcass weight (4.38 kg), while decreased (p < 0.01) average daily feed intake (ADFI, 0.74 kg/d; p < 0.01) and the feed:gain (F/G, 15.36) ratio. The CAT, GSH-Px activities and GSH in serum, liver and spleen, and the levels of IgA, IgG, IgM, IL-2, IL-4 and IL-1β in serum of FPG-fed goats were significantly higher (p < 0.05) than those of NPG-feeding goats. Further, we found that FPG feed is rich in nutrients with Lactobacillus (65.83%) and Weissella (17.80%). Results for gastrointestinal microbiota composition showed that FPG-feeding significantly enhanced the abundance of Lactobacillus and unidentified Clostridiales, and reduced Anaerovibrio and Methanobrevibacter. Meanwhile, Spearman’s correlation analysis showed that these microbiotas were closely related to the improvement of oxidative stress and immune indexes of goats.DiscussionThese results demonstrated that FPG-feeding not only reduces oxidative stress and improves ROS clearance to enhance antioxidant defense system, but also improves gastrointestinal microbiota to enhance immune function by overcoming the adverse effects of heat stress, and further improve growth performance of goats.

“…Resource diversity in Creole genetics constitutes one major global concern (12). Threats to the Creole goat population include interbreeding with exotic breeds (6,26), the economic pressure related to traditional breed abandonment towards intensive management systems (41), and the global trend regarding livestock intensification, specialization, and desertion of marginal lands (2).…”

The objective was to implement a participatory process involving rescue and conservation of Creole goats in agro-silvopastoral systems, as a development strategy for the indigenous and marginalized region of the Mountains of Guerrero (MG), Mexico. The study focused on the caprine agroecosystem, documenting aspects of goat development and identifying caprine areas in 13 municipalities, zoometrically characterizing 680 goats. One hundred and ten goat producers were interviewed for evaluating farmer perception of goat production. Fifty-seven producers were trained in holistic management, and four producers raised 300 goats in outstanding herds. Data were analyzed using social networks, principal component analysis and correspondence analysis. Two goat agroecosystems were identified: 1) agro-silvopastoralism, with crossbreeding of goat populations and, 2) traditional systems, involving grazing of Creole goats on native vegetation. We identified three types of goats: 1) Mixteco mosaic (61%), 2), Pastoreña (31.8%), and 3) Crossbreeds (7.2%), based on bicoastal diameter, chest depth, body length, thoracic perimeter, height at withers, shoulder point width and liveweight. Smallholder goat farmers in the MG preferred Creole goats for their greater productivity and better environmental adaptation. Highlights: Farmer-participatory programs to rescue and conserve the Creole goat breed. Goats agro-silvopastoral systems with low resource smallholders. Sustainable utilization of Creole goats. Goat production systems in the Mexican Mountains.

“…One effort to improve the genetic quality of Kacang goats was through crossing with Boer buck goat. Boer goat was a beef type with fast body growth, good meat quality, and parasitic tolerance (Chong et al, 2019;Elieser et al, 2012;García-Muñiz et al, 2019). Boer has weaning weights 23.4±9.7 kg at the age of 112 days (Menezes et al, 2016) and adult male 120-150 kg at the age of 2-3 years (Nurgiartiningsih et al, 2006).…”

This study aimed to identify the variation of 5’UTR Myostatin (MSTN) gene and its association to body weight in Boer, Kacang, and Boerka goats. DNA samples were obtained from 149 heads of the goats from the Indonesian Goat Research Center, Sungei Putih, North Sumatera. Polymorphism identification was conducted by direct sequencing and PCR-RFLP with DraI as the restriction enzyme for indel g.1256/TTTTA. Analysis of variance for body weight was carried out using the General Linear Model (GLM). The 5’UTR MSTN gene|DraI was monomorphic in Kacang but polymorphic in Boer and Boerka. Genotype frequencies for Boer 0.40(AA), 0.43(AB), 0.17(BB); Kacang 1.00(AA); Boerka 0.53(AA), 0.37(AB), 0.10(BB). The allele frequencies for Boer 0.62(A), 0.38(B); Kacang 1.00(A); Boerka 0.72(A), 0.28(B), respectively. AB was the most frequent genotype among Boer, but AA was the most frequent in Kacang and Boerka. Indel g.1256/TTTTA has a significant effect (P<0.05) only on birth weight (BW) of Boer, but no significant effect on other bodyweight parameters both in Boer and Boerka.AA genotype has the highest BW (P<0.05) than AB, but it’s not significantly different from BB. Indel g.1256/TTTTA could be used as a genetic marker for the birth weight of Boer but not in Boerka goats.
