This study was conducted to determine the effect of cottonseed meal (CSM) incorporated into laying rations in place of soybean meal (SBM) at different ratios on yield traits. The birds began to lay at 6th week, 180 female and 45 male quails were used in laying period experiment. Birds were fed with rations containing 20% CP and 3000 Kcal/kg ME up to 20-week age (Laying period). CSM as a substitute, five different rations of the protein content (0, 30, 58, 86 and 100%) for SBM to basal diets based on corn-soybean meal were used. The results showed that there were no differences in terms of egg yield traits, cumulative feed consumptions and viabilities during the laying period. The highest dry shell rate and shell thickness were obtained from 5th group and 1st group, respectively. As a result, adding CSM instead of SBM in laying period were no significantly differences in terms of egg production and egg quality in laying period.

This study aimed to evaluate the effect of different amounts of incubated samples on the kinetic parameters of in vitro fermentation of roughage and concentrated food used for feeding ruminants. Samples were prepared using 200, 300, 400, and 500 mg of air-dried roughage and concentrated sample, ground to 1 mm, and placed in 120 mL glass flasks. Next, inoculum and McDougal solution were added, and the readings were obtained using a semi-automated pressure transducer up to 96 h after the beginning of the incubations. Gas production of the non-fibrous fraction increased linearly (P < 0.05) for sugarcane, Marandu grass silage, corn silage, dried corn distillers’ grains with solubles, dried brewer’s yeast, bean residue, wet brewer’s grains, sunflower meal, and Jatropha meal; quadratically (P < 0.05) for Napier grass silage and cottonseed meal; and cubically (P < 0.05) for castor meal and soybean meal. The degradation rate of the non-fibrous fraction reduced linearly (P < 0.05) for sugarcane, Napier grass silage, and castor meal; quadratically (P < 0.05) for Marandu grass silage; and cubically (P < 0.05) for corn silage, soybean meal, dried corn distillers’ grains with solubles, bean residue, and cottonseed meal. Gas production of the fibrous fraction increased linearly (P < 0.05) for Napier grass silage, Marandu grass silage, corn silage, dried corn distillers’ grains with solubles, bean residue, wet brewer’s grain, cottonseed meal, and sunflower meal; quadratically ( < 0.05) for Jatropha meal; and cubically (P < 0.05) for sugarcane, castor meal, and soybean meal. The degradation rate of the fibrous fraction increased linearly (P < 0.05) for Napier grass silage, dried corn distillers’ grains with solubles, dried brewer’s yeast, wet brewer’s grains; quadratically (P < 0.05) for corn silage and castor meal; and cubically (P < 0.05) for sugarcane, Marandu grass silage, and bean residue. The lag time reduced linearly (P < 0.05) for castor meal and dried corn distillers’ grains with solubles; quadratically (P < 0.05) for Napier grass silage; and cubically (P < 0.05) for sugarcane, Marandu grass silage, corn silage, soybean meal, bean residue, cottonseed meal, sunflower meal, and Jatropha meal. Thus, our findings suggest that the kinetic parameters of in vitro fermentation were affected as a function of the amount of incubated sample.

Six male Landrace x Large White pigs (25 kg liveweight) were fitted with T-shape cannulae in the terminal ileum. The pigs were fed 1.2 kg dry matter per day containing 4.5 g threonine/kg of diet from continuous belt feeders. The apparent digestibility of dry matter (DM) to the terminal ileum was 0.91, 0.87, 0.85, 0.81, 0.80 and 0.75 for pigs given diets containing milk, fish meal, soybean meal, meat meal, sunflower meal and cotton seed meal respectively. The apparent digestibility of nitrogen (N) to the terminal ileum was 0.87, 0.87, 0.86, 0.86, 0.81 and 0.74 for pigs given diets containing milk, fish meal, soybean meal, sunflower meal, meat meal and cottonseed meal, respectively. The true digestibility of threonine to the terminal ileum was 0.96, 0.95, 0.90, 0.87, 0.80 and 0.66 for the diets containing milk, fish meal, sunflower meal, soybean meal, meat meal and cottonseed meal, respectively.

Abstract This study evaluated the effect of different sources of nitrogen [soybean meal (SM); cottonseed meal (CM); cottonseed + urea (CU); and urea (U)] associated with spineless cactus on intake, digestibility, performance, carcass characteristics and meat quality of confined lambs. Forty male Santa Inês sheep, uncastrated, with initial body weight of 23.00 ± 1.66 kg were distributed in random blocks design and slaughtered after 58 days of confinement. Dry matter (DM) intake (1.16 ± 0.19 kg/day) did not differ (P > 0.05) between nitrogen sources, but the intake of crude protein (CP) and non-fibrous carbohydrates (NFC) was lower (P < 0.05) for sheep consuming CU. Sheep fed with diets containing U had lower digestibility of DM, CP and NFC (P < 0.05). The average daily gain (0.15 ± 0.04 kg/day) and the slaughter body weight (32.07 ± 2.86 kg) did not differ between nitrogen sources, but the cold carcass and loin weight was lower (P < 0.05) for sheep fed with U. The water retention capacity and meat protein content were greater (P < 0.05) for animals fed with SM. Soybean meal or cottonseed meal associated with spineless cactus-based diets for sheep meat production are recommended because it allows greater DM digestibilityand improves carcass characteristics and physicochemical composition of the meat.

<p>Objetivou-se avaliar o efeito da substituição do farelo de soja pelo farelo de algodão em suplementos múltiplos sobre as características nutricionais e desempenho produtivo de novilhas de corte em fase de recria em pastagens de <em>Brachiaria decumbens </em>no período da seca. Foram utilizadas 24 novilhas de corte nelore com idade e peso médio inicial de 8 meses e 210±6 kg, respectivamente. O delineamento foi inteiramente casualizado com quatro tratamentos e seis repetições. Os suplementos continham aproximadamente 30% de proteína bruta (PB) e substituição progressiva do farelo de soja pelo farelo de algodão em 0, 50 e 100%. Aos animais do tratamento controle foi fornecida apenas mistura mineral <em>ad libitum </em>e aos demais tratamentos foram fornecidos 1,0 kg/animal/dia de suplemento. Não houve diferença de GMD entre os animais suplementados e os animais controle (P&gt;0,10). A suplementação aumentou apenas o consumo de proteína bruta (PB) (P&lt;0,10). O nível de substituição de farelo de soja pelo farelo de algodão não afetou (P&gt;0,10) o consumo nos animais suplementados. A suplementação ampliou os coeficientes de digestibilidade aparente (P&lt;0,10) da MO, PB, CFN e NDT com exceção do EE e da FDNcp (P&gt;0,10). Observou-se efeito linear positivo (P&lt;0,10) do nível de substituição de farelo de soja pelo farelo de algodão sobre a digestibilidade da MO, CNF e NDT. Houve efeito da suplementação e do nível de substituição (P&lt;0,10) sobre o teor de nitrogênio ureico no soro e nitrogênio ureico na urina. Não houve efeito da suplementação e do nível de substituição sobre o fluxo de nitrogênio microbiano ao intestino (NMIC) e eficiência de síntese de proteína microbiana (EFM) (P&gt;0,10). Foi verificado efeito linear decrescente (P&lt;0,10) da substituição sobre a relação nitrogênio microbiano/ nitrogênio ingerido (NMICR). Conclui-se que a substituição do farelo de soja pelo farelo de algodão em suplementos múltiplos durante a época seca não prejudica o desempenho produtivo de novilhas de corte.</p>

Abstract Background The aim of this study is a comparison between some different protein sources in sheep rations to identify the best protein source that achieves the highest production performance and the lowest economical feed efficiency. Twenty Farafra male lambs weighed on average 41.39 ± 1.66 kg were divided randomly into four similar groups of 5 animals each. All groups were fed on concentrate feed mixture (CFM) at 3% of their body weight, and wheat straw fed ad lib. to replace 100% of the soybean meal (SBM) as a source of protein, black cumin seed meal (BCSM), cottonseed meal (CSM) and sesame seed meal (SSM) were incorporated into the CFM. The feeding trial extended for 66 days followed by digestibility and nitrogen (N) balance trials. Results The results indicated no difference in total feed intake between experimental groups. Digestibility of crude protein, ether extract and crude fiber for animals fed CSM ration was higher (p < 0.05) than those fed the other rations. On the other hand, the CSM ration recorded a higher value of digestible crude protein than SBM and BCSM rations. Lambs gave rations containing CSM was higher (p < 0.05) average daily weight gain compared with those fed the other rations. Lambs that fed CSM ration were better to feed conversion as kg dry matter intake/kg gain than those fed the other rations. Relative economic efficiency was the best for CSM ration as compared to other protein sources. Nitrogen balance value of sheep fed CSM diet had the highest (p < 0.05) value compared with those fed different sources. Rumen fermentation showed that the pH value was the lowest with SSM, NH3-N concentration was higher for BCSM and SSM, and total volatile fatty acids were higher for SBM compared with the other rations. Conclusion It could be concluded that cottonseed meal was the best treatment for digestibility coefficient, average daily gain, highest nitrogen balance, better feed conversion ratio and also the best economic efficiency compared to soybean meal, black cumin seed meal and sesame seed meal treatments. It can replace 100% soybean meal by cottonseed meal in sheep ration when economics is to be considered.
