“…The faster growth rate of single-born kids than multiple-born kids during the pre-weaning period (WG1) and lower or similar performance afterward is consistent with Deribe et al (2015) and Mohammadi et al (2012) who reported that multiple-born kids gained the least weight during the pre-weaning period, but not during the post-weaning period. Competition for uterine space during pregnancy and milk after parturition could explain the reduced growth rate of multiple-born kids during pre-weaning.…”

“…In Ethiopia, however, there is a scarcity of information. Few pieces of research have reported growth performance of 50% Boer level or F1 crossbred goats ( Belay et al., 2014 ; Deribe et al., 2015 ), and little is known about the influence of factors and their interactions on the growth and Kleiber ratio for different levels of Boer goat. Therefore, this study aims to evaluate the growth and efficiency-related traits and to identify genetic and non-genetic factors affecting the performance of different levels of crossbred goats.…”

The growth and efficiency-related traits of the Boer x Central Highland goats raised semi-intensively were evaluated. Besides, genetic and non-genetic factors affecting growth and efficiency-related traits were identified. Data were collected over a period of nine years in a flock of Boer crossbred goats and analyzed using general linear model procedure of SAS. The overall least-squares mean live weight at birth, 3-, 6-, 9-and 12 months of age were 2.52 AE 0.01, 9.81 AE 0.13, 13.8 AE 0.15, 17.8 AE 0.19, and 20.5 AE 0.29 kg, respectively. The average weight gains from birth to 3 months, 3 to 6, 6 to 9 and 9-12 months of age were 80.3, 37.5, 41.9, and 31.2 g day À1 , respectively. Boer blood level, birth type, season and year of kidding had a significant effect on growth traits. The overall least-squares mean of Kleiber ratio from birth to 3 months, 3-6 months, 6-9 months, and 9 month to yearling age were 13.99 AE 0.11, 5.23 AE 0.14, 4.66 AE 0.16, and 2.95 AE 0.18, respectively. Parity, birth type, Boer blood level, season and year of birth had a significant influence on the expression of efficiency-related traits (Kleiber ratios) in different growth phases. In terms of growth performance and efficiency-related traits, F2 and F3 crossbred goats did not show any benefit over F1 crossbred goats. Increasing Boer blood level above 50% would be worthless under the existing minimal input production system. Therefore, besides to improving the management of goats, producing the first filial generation would be suitable for medium to high input production systems.

“…The fourth finding was that mean BW of Boer crossbreds were higher than mean BW of indigenous goats, as reported elsewhere (Deribe et al 2015;Kalenga et al 2015), but smaller than the 28.7 kg theoretically expected in the absence of heterosis. This theoretical value was obtained by averaging the weight of our indigenous goats (22.3 ± 4.1 kg) and the weight of pure Boer goats raised under extensive humid tropical conditions (35.1 ± 1.32 kg) as reported by Nguluma et al (2013).…”

Similarly, a small BW increase was reported for crossbred goats in Ethiopia (Deribe et al 2015): they stated that birth and weaning weights of Boer crossbreds were significantly higher than weights of local breeds, but the difference dwindled as the age of kids advanced. These observations may be explained by the management conditions not allowing animals to express their genetic potential (e.g.…”

Characteristics of smallholders’ goat production systems and effect of Boer crossbreeding on body measurements of goats in Burundi

et al. 2020

As part of a national action plan to manage animal genetic resources in Burundi, we characterized smallholders' goat production systems and assessed the effect of Boer crossbreeding on animal body measures. To that end, 319 farmers were surveyed in the five agro-ecological zones of Burundi and the zootechnical measures of 939 adult goats were taken. Cluster analysis of the goat production systems resulted into two opposed groups and one intermediate. On the one hand, there are the dry lowlands systems characterized by large herds composed mainly of indigenous animals grazing freely, and having high market characteristics. On the other hand, there are the humid highlands systems characterized by small herds composed of indigenous and crossbred animals in stall feeding or herding/tethering systems, and by low market characteristics. Fixed effect linear models were used to evaluate the effect of Boer crossbreeding on body weights and linear body measures, after adjustment for age, sex, grazing systems and agro-ecological zones. Results showed that least square means for body weights of adult Boer crossbreds were 4.74 kg higher than those of indigenous goats, which was lower than expected. Least square means for linear body measures of Boer crossbreds were significantly higher than those of indigenous breeds: differences in chest girth, body length and height at withers were 4.88 cm, 5.59 cm and 4.82 cm, respectively. Goats were heavier and greater in linear measures in lowlands than in highlands. The advantages and issues of a selection programme within indigenous breeds are discussed as an alternative to the crossbreeding programme.

“…In Ethiopia, researches undertaken on goat reproductive performance were largely based on single trait, often used as part of a breed performance evaluation program on research stations (Belay et al 2014 ; Solomon et al 2014 ; Deribe et al 2015 ). However, technological solutions developed through conventional station-based agricultural research have failed to achieve the expected results in the small-scale farming sector of the developing world (Stroud et al 2000 ).…”

Reproductive performance is a key determinant for the efficiency of goat production. Regular monitoring of reproductive efficiency is essential to assess management and to avoid financial losses due to poor performance. To allow more objective measurement and comparisons over time, we propose a novel quantitative approach for defining annual reproductive performance by combining common performance indicators into a goat flock index. Commonly used reproductive performance measures were collected from 242 goat flocks in four districts in dryland of Ethiopia between July 2018 and February 2019. Principal component analysis (PCA) was performed to identify biologically meaningful latent components that explain annual reproductive output (ARO) and annual reproductive wastage (ARW). Together with the remaining annual reproductive performance measures, the ARO and ARW components were included in a PCA to derive an algorithm for a goat annual reproductive performance index (G-ARPI). One component representing variation in kidding interval, PCARO1 and PCARW1 was extracted and normalized to a 10-scale value. The flocks were classified into good performing (15.63%) with index > 8.5, moderately performing (48.21%) with index values ranging from 6.5 to 8.5 and poor performing (36.16%) with index < 6.5. Good performing flocks have higher scores for reproductive output measures, lower scores for reproductive wastage and lower kidding interval. The proposed G-ARPI can be used as an objective tool to compare reproductive performance between management systems, evaluate the costs of poor reproductive management and will be useful for economic models that aim to identify the most cost-efficient intervention option and monitor the impact of interventions. We present here the index for goat production in dryland systems in Ethiopia; the approach can easily be adapted to other production systems elsewhere.
