Attempts to reduce ruminal degradability of CM through gamma irradiation have generated conflicting results. While this strategy has the potential to reduce CM degradability, the optimal radiation dose is unknown for this valuable co-product. Therefore, this in vitro ruminal fermentation study was designed to evaluate the efficacy of gamma irradiation to protect CM protein from ruminal degradation. Canola meal was irradiated at 0 (CM0), 15 (CM15), 30 (CM30), 45 (CM45), 60 (CM65), 75 (CM75), and 90 kGy (CM90). Irradiated CM was then analysed for proximate composition and incubated with rumen fluid to determine in vitro degradability of dry matter (DMD) and nitrogen (ND). The data were evaluated for linear and quadratic effects using response surface regression analysis. Neutral detergent fibre and acid detergent fibre linearly decreased as irradiation dosage increased. Quadratic responses were observed for total nitrogen (N) content, DMD12, and DMD36 in response to increasing irradiation dosage. Gamma irradiation linearly increased the rapidly soluble fraction (a) and effective degradability (ED) of dry matter. There were no irradiation effects on ND12, ND36, ND48, fractional rate constant (c), and potential degradability, but significant quadratic trends were observed for ND24, a, slowly degradable fraction (b), and ED of N. It was concluded that although gamma irradiation altered the chemical composition of CM, it was not an effective method to protect CM from extensive ruminal degradation","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"48 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80300519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No substantial difference in growth performance between the YH, SY, and SDDP groups was found; however, compared with the CON group, the performance of these three groups was substantially improved. The contents of serum globulin and ALP in the CON group were markedly decreased compared to the other groups, but the AST level was substantially increased. The IL-10 concentration in the other groups was substantially higher than the CON group, and the highest content was in group YH; the TNF-α content showed an opposite trend. The levels of serum IgG and IgA in the CON group were the lowest among all groups. There were substantial differences among the groups in villi height and crypt depth in the duodenum, jejunum, and ileum.

This necessitates paradigm shifts to improve agricultural efficiency. However, South African wool production has continuously declined over the past three decades. The study analysed the efficiency of smallholder wool farmers and identified the determinants of technical inefficiency in wool production in Thaba ‘Nchu and Botshabelo in the Mangaung Metro (Free State province, South Africa). A multistage sampling technique was used to select 351 participants. A stochastic frontier model was employed to analyse the efficiency of wool farmers. The results indicate that increases in feed and veterinary costs negatively affect the efficiency of smallholder wool production. Wool quality and use of social media were found to have a negative and statistically significant influence on the variation in the inefficiency of wool production (i.e., as these variables increase, inefficiency decreases). Poor extension services and poorly managed farmers’ associations increase the inefficiency of smallholder wool producers. Furthermore, only 7% of smallholder farmers were efficient, and most smallholder wool farmers were not producing at full capacity; there is thus much room to improve production. To increase the efficiency of smallholder wool production in Mangaung, it is recommended that farmers are trained to improve the quality of their wool and, consequently, increase the wool price. Further recommendations include improvement of extension services, better management of farmers’ association","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"33 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79089374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Goats on the browser diet lost weight in March, May, and in August whereas those on the control diet gained weight. The serum urea concentration of goats consuming browser diets in May and August (1.8–3.3 mmol/l) was lower than the normal range, consistent with animals failing to derive their protein requirements from the diet.

A total of 3343 records of Turkish Saanen kids were collected in 2019. The importance and order of the effects of environmental factors, such as gender, birth type, sex, birth weight, farm, season of birth, weight at death, and maternal age at the kid’s mortality were determined by using the decision tree statistical method. As a result of this study, the farm effect was the first effective factor in the survivability of kids, and death was less common in small farms (F3), with a rate of 7.8%. The death times of kids were divided into four groups: birth–first 24 hours (M1), 1–7 days (M2), 7–30 days (M3), and 30 days–weaning (90 days) (M4). Deaths were highest in M2 with 40.1% and least in M3 with 5.7%. The death weight variable had a primary effect on deaths. This was followed by birth weight, then farm variables. Two other factors came to the forefront to increase the survivability of the kids: deaths could be greatly reduced by providing good nutrition to the mothers in the prenatal period and offering good management, especially in the first week after birth, to obtain offspring with higher birth weights.","PeriodicalId":21869,"journal":{"name":"South African Journal of Animal Science","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75297569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
