“…The difference in LWP among farming systems could be attributed to the difference in the amount of rainwater evapo-transpired in feed production across farming systems. The LWP values found in our analysis were generally low and comparable with the values reported by other researchers (Amede et al, 2009a;Peden et al, 2009;van Breugel et al, 2010). The LWP values were particularly low in farming systems dominated by barley-potato and maize-sorghum crop mixtures.…”

“…The observed low LWP values in most farming systems can partly be attributed to the low level of meat and milk production per animal. As a consequence, the water requirements for maintenance, growth and milk production are very high in these systems (van Breugel et al, 2010). The low level of LWP reported in the farming systems could also be associated with the widespread land degradation in the Ethiopian highlands (Kato et al, 2011;Alemu and Kidane, 2014).…”

Livestock production is a major consumer of fresh water, and the influence of livestock production on global fresh water resources is increasing because of the growing demand for livestock products. Increasing water use efficiency of livestock production, therefore, can contribute to the overall water use efficiency of agriculture. Previous studies have reported significant variation in livestock water productivity (LWP) within and among farming systems. Underlying causes of this variation in LWP require further investigation. The objective of this paper was to identify the factors that explain the variation in LWP within and among farming systems in Ethiopia. We quantified LWP for various farms in mixed-crop livestock systems and explored the effect of household demographic characteristics and farm assets on LWP using ANOVA and multilevel mixed-effect linear regression. We focused on water used to cultivate feeds on privately owned agricultural lands. There was a difference in LWP among farming systems and wealth categories. Better-off households followed by medium households had the highest LWP, whereas poor households had the lowest LWP. The variation in LWP among wealth categories could be explained by the differences in the ownership of livestock and availability of family labor. Regression results showed that the age of the household head, the size of the livestock holding and availability of family labor affected LWP positively. The results suggest that water use efficiency could be improved by alleviating resource constraints such as access to farm labor and livestock assets, oxen in particular.Keywords: mixed-crop livestock systems, livestock feed, water use efficiency, livestock water productivity ImplicationsLivestock production is one of the major consumers of fresh water, and the influence of livestock production on water resources is increasing because of the growing demand for livestock products. The results suggest that water use efficiency could be improved by alleviating resource constraints such as access to farm labor and livestock assets, oxen in particular. The findings of this research help in making decisions about where to invest scarce resources in order to improve water use efficiency in livestock production under rain-fed conditions.

RESUMOA produtividade hídrica é um indicador ainda pouco considerado na produção animal. Isso se justifica por a água ser ainda entendida pelos atores da cadeia de produção como um recurso natural abundante disponível em quantidade e qualidade. O objetivo deste estudo foi avaliar o impacto de estratégias nutricionais em indicadores hídricos para suínos em crescimento e terminação. Cinco estratégias foram avaliadas: dieta testemunha (T1), com redução do nível de proteína bruta (T2), com fitase (T3), com minerais orgânicos (T4) e as três estratégias nutricionais juntas (T5). O indicador de produtividade hídrica é definido como a relação da quantidade de produto pelo total de água consumida para gera-lo. Os seguintes indicadores de produtividade hídrica foram calculados: peso total (kg. O T5 apresentou as melhores produtividades, ou seja, para cada litro de água consumida, se produziu maior quantidade de produto. A produtividade de peso total nesse tratamento foi de 3,0 kg L -1 , enquanto no T1 foi de 2,5 kg L -1 . O T3 apresentou as menores produtividades. A produtividade hídrica nutricional foi de 2.512, 2.763, 2.657, 2.814 e 3.039 kcal L -1 , respectivamente para T1, T2, T3, T4 e T5. A utilização de estratégias nutricionais reduz o consumo de dessedentação e, consequentemente, melhora a produtividade hídrica. As melhores produtividades são observadas quando se utiliza as estratégias simultaneamente.Palavras-chave: aminoácidos, dessedentação, fitase, minerais orgânicos. Impact of nutritional strategies on water productivity indicators for pigs ABSTRACTThe productivity of water is a poorly considered indicator in animal agriculture. This is because water is a resource still believed by persons in the production network to be abundant and of good quality. The aim of this study was to evaluate the impact of nutritional strategies in water productivity indicators for growing and slaughtering pigs. Five strategies were evaluated: control diet (T1), with a reduction in the level of crude protein (T2), phytase (T3), organic minerals (T4) and the three nutritional strategies combined (T5). The water productivity indicator is defined as the quantity of product by water used. The following indicators were calculated: total weight (kg L -1 ), cold carcass (kg L -1 ) lean carcass (L kg -1 ), and nutrition (kcal L -1 ). T5 showed the best productivities for each liter of water used. The total weight productivity in this treatment was 3.0 kg L -1 , while in T1 was 2.5 kg L -1 . T3 had the lowest productivities. The nutritional water productivities were 2,512, 2,763, 2,657, 2,814,
