The performance of Prosopis juliflora and Leucaena leucocephala was investigated at plant spacings of 1 × 0.5, 1 × 1, 1 × 1.5, 1 × 2 and 1 × 2.5 m corresponding to a tree density of 20,000, 10,000, 6,666, 5,000 and 4,000 ha-1, respectively, to identify the most suitable plant spacing for the optimum biomass harvest per unit area. The overall performance of L. leucocephala was superior to P. juliflora under most parameters measured, except for the calorific value. The performance of both species in terms of the plant height, stem diameter and number of trunks was affected by the population density at age 6 mths and there were significant increases at wider spacings (1 × 2 and 1 × 2.5 m) when the age advanced to 12 mth. There were significant differences in the biomass production per tree and better total above ground biomass results were obtained with plantings at wider spacings at both 6 and 12 mth of age. However, the total above ground biomass yield per hectare of both species increased markedly with increasing plant density at both 6 and 12 mth of age and this revealed that both species can be grown at closer spacing (1 × 0.5 m).

An experiment was conducted to identify rice varieties resistant to blast disease. Samples of 311 genetically diversified varieties/accessions comprised of landrace (263), improved (43) and wild (5) rice varieties/accessions were provided by the National Rice Gene Bank of Thailand. The screening for blast at the seedling stage was done using 29 diversified blast isolates. The blast isolates were collected from seven provinces (Phitsanulok, Ubon Ratchathani, Khon Kean, Chiang Rai, Nong Khai, Chaiyaphum and Udon Thani) of Thailand. The results indicated a total of 35 varieties/accessions (25 landrace, 9 improved and 1 wild) were resistant to all tested blast isolates. The 25 resistant landrace varieties were collections from Northern (10), Northeastern (9) and Southern (6) Thailand. Moreover four of the resistant landrace varieties (GS23107, GS19769, GS20874 and GS23774) were highly resistant with no symptom of the disease. From this study, it can be suggested that the resistant landraces from the Southern, Northern and Northeastern regions could be used as sources of resistant varieties in designing future breeding programs aimed at developing disease-resistant genotypes.

This study was designed to examine the existence of a genotype × region interaction on milk production traits in Holstein crossbred dairy cows in Thailand. The data set for this study was provided by Department of Livestock Development of Thailand. The data were divided into five regions (Central, East, North, Northeast and West). The factors having genotype × region interaction on milk production traits were region, year-season of calving, breed group and breed group × region interaction. The investigated traits were actual total milk yield (ATMY), 305 d milk yield (MY305) and adjusted 305 d milk yield (AJ305), respectively. The breed group of cow had a significant (P < 0.05) effect on MY305 and a highly significant (P < 0.01) effect on ATMY and AJ305 while the effect of year-season of calving and region had very highly significant (P < 0.001) effects for all the studied traits. Breed group × region had a highly significant interaction (P < 0.01) for the milk production traits. The estimated heritability for the milk production traits ranged between 0.17 to 0.24 for the Central region and 0.29 to 0.57 for the Eastern region. It was suggested that the performance of breed group of cows from different regions should differ significantly or there was a genotype × region interaction in this particular study.

Twenty Afar male sheep with initial mean body weight ± SD of 17.87 ± 1.19 kg were used to evaluate the effect of replacing commercial feed with Prosopis juliflora pods and leaves on growth performance, carcass and meat quality characteristics. Animals were equally divided into four dietary treatment groups for 120 d (Rhode grass hay (RGH), RGH + 300 g ground P. juliflora pods (PJP), RGH + 150 g each ground P. juliflora pods and leaves mix (PJPLM) and RGH + 300 g commercial concentrate mix (CCM) per head per day). Total dry matter and crude protein intakes increased (P < 0.05) in treatments supplemented with ground PJP and CCM. The average weight gain and meat quality parameters obtained by supplementing with 300 g ground PJP were significantly higher than the RGH and PJPLM treatment groups, but were comparable with that of CCM. The present study demonstrated the potential of using PJP for Afar lambs without adverse effects on growth and carcass characteristics. However, the intake of PJP reduced when mixed with leaves and this indicates the leaves are unpalatable.

This study aimed to estimate the direct genetic effects on actual milk yield and lactation length of Holstein crossbred dairy cows in the Aownoi Dairy Cooperative. The data comprised 869 lactation records from 850 cows that had calved during 2009-2010. The data were analyzed by the Restricted Maximum Likelihood Method and applying the Average Information Algorithm (AIREML) using univariate analysis. The factors having a direct effect on actual milk yield and lactation length were the year-season of calving (YS), the breed group of the cows and the lactation number. The investigated traits were lactation length and actual milk yield. The results showed that the overall mean (± SE) for milk yield and lactation length was 4,484.84 ± 13.60 kg.cow-1.lactation-1 and 376.94 ± 0.34 d, respectively. The lactation number had a significant effect on the actual milk yield but there was no significant effect of breed group, lactation number and year-season of calving on the lactation length. Estimates of heritability for the actual milk yield and lactation length were 0.22 ± 0.08 and 0.26 ± 0.09, respectively.

The experiment was conducted to determine the supplementary feeding value of ground Prosopis juliflora pod (Pjp) and cottonseed meal (CSM) and their mixtures on feed intake, body weight gain and carcass parameters of Afar sheep fed a basal diet of pasture hay. Twenty-five yearling fat-tailed Afar rams with mean initial live weight 17.24 ± 1.76 kg (mean ± SD) were used in a randomized complete block design. Animals were blocked on their initial body weight. The experiment was conducted for 12 weeks and carcass evaluation followed. Treatments were hay alone ad libitum (T 1) or with 300 g CSM (T 2), 300 g Pjp (T 5), 2:1 ratio (T 3) and 1:2 ratio of CSM: Pjp (T 4). The CP contents of the hay, CSM and Pjp were 10.5, 44.5 and 16.7 %, respectively. Hay DM intake was higher (P < 0.05) for non-supplemented and total DM intake was lower in non-supplemented. Average daily weight gain (ADG) was lower (P < 0.05) for T 1 compared to all supplemented treatments except T 5. Hot carcass weight and rib-eye muscle area also followed the same trend like that of ADG. Compared with feeding hay alone, supplementing with CSM or a mixture of CSM and Pjp appeared to be a better feeding strategy, biologically, for yearling Afar rams. © 2014 Springer Science+Business Media Dordrecht.

The study was conducted in Chifra district in Awsi-Resu zone of Afar Regional State to explore production objectives and strategies of sheep and goats in pastoral and agro-pastoral production systems. Cross-sectional survey with systematic random selection of 180 households (90 households from each production system was conducted. Descriptive statistics, t test, chi-square test, analysis of variance, and ranking method were employed in analyzing data using JMP-5 software. In pastoral production system, sheep and goat were primarily reared for household milk consumption, followed by live animal savings and income, while in agro-pastoral production system, sheep and goat are primarily reared for income, followed by household milk consumption and manure supply, as live animal savings. Overall mortality rates of sheep and goats (4 to >12 months of age) were 9 and 9.5 % in pastoral production systems while 7 and 6 % in agro-pastoral production system. Average age at first mating, kidding interval, days of mating after birth, weaning age, lactation length, litter size, slaughtering age, and marketable age of sheep and goats in pastoral production system were 7.4 months, 358 days, 29 days, 4.2 months, 3.1 months, 1.5 lambs, 7.4 months, and 14 months, respectively, while in agro-pastoral production system, they are 6.9 months, 353.3 days, 28 days, 3.2 months, 1.6 lambs, 6.4 months, and 14.5 months, respectively. It was concluded that production system-based development interventions could help to increase the productivity of sheep and goats and thereby enhance the livelihood of smallholders. © 2014, Springer Science+Business Media Dordrecht.

Based on data generated from 180 randomly selected households with children age under five years old in Aysaita district of Afar region of Ethiopia, this study explored prevalence of malnutrition and scrutinized household characteristics, maternal characteristics, specifics of the child and economic variables associated with child malnutrition. The height-for-age Z-scores (HAZ), weight-for-height Z-scores (WHZ) and weight-for-age Z-scores (WAZ) were used to measure the extent of stunting, wasting and underweight, respectively. The results revealed that prevalence of long term nutritional imbalance and malnutrition status indicator (i.e. stunting) was 67.8%. The short term measure (wasting) was found to be 12.8% and underweight was found to be 46.1%. Moreover, children in households which are headed by women, and characterized by more dependency ratio, less access to assets, health services and institutions are more likely to be undernourished. © 2013 The Korean Nutrition Society and the Korean Society of Community Nutrition.
