“…It was also claimed that animals in the early lactation period were shown more effort to meet its energy needs and so, there is a decrease in total protein and lipid content of the adipose tissue 24,25 . Transition phase from early lactation period to late lactation period is regulated by a homeostatic mechanism comprising metabolic interactions and body fuel distribution, and this mechanism is primarily based on glucose 26 .…”

SummaryThe purpose of the study was to investigate effects on oxidant and antioxidant balance of early and late lactation period in goats. Blood samples used in study were obtained from Halep goats in early and late lactation period. Oxidative stress index (OSI) and lipid hydroperoxide (LOOH) and total oxidative status (TOS) and total antioxidant status (TAS) were analyzed to determined of oxidant and antioxidant balance. Plasma TOS, OSI and LOOH levels in early lactation period were significantly higher (P<0.001) than late lactation period of goats, while lower (P<0.001) level of TAS. It was concluded that lipid peroxidation decreased and antioxidant defence system mechanism in late lactation period in goats served as more positive than early lactation period. Keywords: Goat, Lactation, Total antioxidant status, Total oxidant status, Oxidative stress Erken ve Geç Laktasyon Periyodunun Keçilerde Plazma Oksidan/Antioksidan Dengesi Üzerindeki Etkileri ÖzetBu çalışmada keçilerin oksidan ve antioksidan dengesi üzerinde erken ve geç laktasyon periyodunun etkilerinin araştırılması amaçlandı. Çalışmada kullanılan kan örnekleri erken ve geç laktasyon periyodunda bulunan Halep keçilerinden elde edildi. Oksidan ve antioksidan dengenin değerlendirilmesi için oksidatif stres indeksi (OSİ), lipid hidroperoksid (LOOH), total oksidan (TOS) ve total antioksidan düzeyleri (TAS) analiz edildi. Erken laktasyon periyodunda plazma TOS, OSİ ve LOOH düzeylerinin geç laktasyon periyodundaki keçilere göre daha yüksek (P<0.001) olduğu belirlenirken, TAS düzeyinin daha düşük olduğu belirlendi (P<0.001). Sonuç olarak, geç laktasyon periyodundaki keçilerde erken laktasyon periyoduna göre lipid peroksidasyonunun azaldığı ve antioksidan savunma sistemi mekanizmasının daha olumlu yönde işlediği kanısına varıldı.

“…In a Dry Puna study, grasslands species loss was diminished and grassland condition improved when rotational grazing was applied (Swinton and Quiroz, 2003). Cañas et al (2003) found that under high grazing intensities, a common occurrence in the Puna, animal performance increases under rotational grazing due to a more efficient use of the forage. …”

“…A study done in Ivory Coast revealed that The effect of climate information herders practice mobile pastoralism because of higher productivity and better health of their livestock than that under sedentary pastoralism (Bassett, 2009). The availability of nutritious pastures during herd mobility is linked to forage selection by livestock resulting into higher fertility and productivity, which yields higher economic returns (Idibu et al, 2016;Cañas et al, 2003;Baumont et al, 2000). Research has shown that controlled grazing results into grazing less nutritious forage especially during the dry season resulting into lower productivity (Idibu et al, 2016).…”

Purpose This paper aims to investigate the effect of using indigenous forecasts (IFs) and scientific forecasts (SFs) on pastoralists’ adaptation methods in Rwenzori region, Western Uganda. Design/methodology/approach Data were collected using a household survey from 270 pastoralists and focus group discussions. The multivariate probit model was used in the analysis. Findings The results revealed that pastoralists using of IF only more likely to be non-farm enterprises and livestock sales as adaptation strategies. Pastoralists using both SF and IF were more likely to practise livestock migration. Research limitations/implications Other factors found to be important included land ownership, land tenure, gender, education level, non-farm and productive assets, climate-related risks and agricultural extension access. Practical implications Increasing the number of weather stations in pastoral areas would increase the predictive accuracy of scientific climate information, which results in better adaptive capacity of pastoralists. Active participation of pastoral households in national meteorological dissemination processes should be explored. Social implications A two-prong approach that supports both mobile and sedentary pastoralism should be adopted in rangeland development policies. Originality/value This study has shown the relevance of IFs in climate change adaptation methods of pastoralists. It has also shown that IFs compliment SFs in climate change adaptation in pastoralism.
