The increasing pressure on maize for human and livestock nutrition, coupled with the cost of maize which keeps increasing, stimulate the use of alternative and locally available sources of energy. This study aimed at contributing to chicken productivity by evaluating effect of pelleted diets with graded inclusion levels of cassava-sweet potato meal (CASPM) as energy substitute for maize on the digestibility, carcass and haematological parameters of Cameroon Kabir chickens. A completely randomised design was used to allocate a total of 315 Kabir chickens (270 hens and 45 rosters) of 23 weeks of age to five dietary formulations T1 (0% replacement of maize with CASPM considered as control diet), T2 (25%), T3 (50%), T4 (75%) and T5 (100%). Animals within the treatments were balanced for weight in each sex, each treatment having 63 Kabir chickens in three replicates of 18 hens and 3 roosters each. The apparent digestibility of metabolizable energy was found to be positive. Lipids apparent digestibility value was negative for diet but positive for other treatments. Crude protein, Ash and crude fibre were all negative irrespective of treatments. The rosters had higher carcass weight than the hens (P<0.05), which in turn had a higher liver to carcass ratio as well as abdominal fats compared to the rosters. No significant difference was observed among other organs. The lowest RBC count was registered for T5 whereas unusual high RBC count was observed for hens from T4. T5 (100% substitution) and T3 (50% substitution) had the highest digestibility mean while T3 (50% substitution) had the lowest FCR. T1 and T3 were found to have the best optimum range blood characteristics. Overall, T3 was the best of the five treatments as neither mortality nor adverse effects on chickens was recorded. Besides, no abnormalities were found upon carcass analysis. It is therefore recommended that 50% substitution of cassava-sweet potato meal as energy substitute for maize shall be used for the improvement and productivity of Kabir chicken production.

This research quantified the economic importance of pest and disease control for agricultural producers in Brazil. The probable economic losses that would result if agrochemicals were not applied to control the observed infestations was evaluated by means of simulations based on experimental data and economic models. Every crop management practices were assumed to be maintained except those related to the use of the agrochemical in question. Primary data from 31 representative producing regions in 14 Brazilian states were used for three harvests seasons of soybeans and corn (2014/2015, 2015/2016 and 2016/2017). The question was: how would observed producers? costs, revenues and profits change if the control of one of the observed pest or disease was suppressed, taking into account the likely rise in market prices that the reduction in supply would cause? The results indicate that the lack of pest and disease control could cause substantial economic losses to producers. For instance, failure to treat soybean rust in 2016/2017 would result in farmers? loss of more than US$ 3.7 billion, because observed aggregate profit of US$2.63 billion would turn into a loss of US$ 1.06 billion. No control of the Spodoptera caterpillar would transform observed soybean farmers? profit of US$2.63 billion into a loss of US$0.46 billion, thus totaling a profitability loss of US$3.08 billion. Avaliação econômica do uso de agroquímicos em duas grandes lavouras brasileira de grãos Esta pesquisa quantificou a importância econômica do controle de pragas e doenças para os produtores agrícolas no Brasil. As prováveis perdas econômicas sem a aplicação de agroquímicos para controlar as infestações observadas foram avaliadas por simulações baseadas em dados experimentais e modelos econômicos. Nas simulações, todas as práticas de manejo foram mantidas, exceto aquelas relacionadas ao uso do agroquímico em questão. Especificamente, os casos das safras de soja e milho em 2014/2015, 2015/2016 e 2016/2017 foram examinados com dados primários de 31 regiões representativas de produção em 14 estados brasileiros. A pergunta foi esta: como mudariam os custos, receitas e lucros dos produtores observados se o controle de uma praga ou doença observada fosse suprimido, considerando o provável aumento dos preços de mercado que a redução na oferta causaria? Os resultados indicam que a falta de controle de pragas e doenças pode causar perdas substanciais na lucratividade dos produtores. O não tratamento da ferrugem da soja em 2016/2017, por exemplo, resultaria em perda de lucratividade de mais de US$ 3,7 bilhões, já que o lucro agregado observado de US$ 2,63 bilhões se transformaria em uma perda de US$ 1,06 bilhão. A falta de controle da lagarta Spodoptera transformaria o lucro observado dos agricultores de soja de US$ 2,63 bilhões em uma perda de US$ 0,46 bilhão, totalizando assim uma perda de lucratividade de US$ 3,08 bilhões.
