“…The supply of whole oilseeds is a way to moderate the release of nutrients in the rumen and thus increase the availability in the small intestine (Dayani, Dadvar;Afsharmanesh, 2011;Zhang, Mustafa;Zhao, 2007), then it may be advantageous to performance of growing goat kids.…”

Twenty-eight Saanen goat kids (16 non-castrated males and 12 females; 14.38±1.60 kg) were used to evaluate the performance and nutritional value of diets. Animals were randomly allotted into a 4x2 (diets x gender) factorial arrangement. Treatments consisted of four different total mixed diets composed of oat hay, soybean meal, mineral supplement, and/or oilseeds replacing ground corn (on dry matter basis), as follows: 1) control (without oilseeds), 2) diet containing 7.9% flaxseed, 3) diet with 7.3% sunflower, and 4) diet containing 8.0% canola. Dry matter intake was higher for animals receiving control diet. Gender did not influence dry matter and nutrient intake. Oilseeds did not affect the average daily gain (ADG) and feed conversion (FC). Flaxseed diet showed more days in feedlot. Males showed better means of ADG, FC and days in feedlot. Diets containing oilseeds had higher values for ether extract digestibility and lower total carbohydrates than the control diet. The energetic value of diets did not alter. The inclusion of flaxseed, sunflower or canola in diets of Saanen goat kids in place (8% on a DM basis) corn, does not improve the performance, however these oilseeds may be used without changing the nutritional value of diets.Index terms: Digestibility, intake, fat supply, goats, performance. RESUMOCom o objetivo de avaliar os efeitos do uso de grão de oleaginosas sobre o desempenho e o valor nutricional das rações, foram utilizados 28 cabritos Saanen (16 machos e 12 fêmeas; 14,38±1,60 kg) distribuídos aleatoriamente em arranjo fatorial 4x2 (rações e sexos). Os tratamentos consistiram em rações compostas por feno de aveia, milho moído, farelo de soja e suplemento mineral e/ou grãos de oleaginosas em substituição ao milho, conforme os seguintes tratamentos: 1) controle; 2) 7,9% linhaça; 3) 7,3% de girassol; e 4) 8,0% de canola. A ingestão de matéria seca foi maior para ração controle. Não houve diferença entre os sexos para ingestão. O ganho médio diário (GMD) e a conversão alimentar (CA) não foram alterados. O número de dias em confinamento (DC) foi maior dentro da ração linhaça. Os cabritos machos apresentaram melhor GMD, CA e DC. A inclusão das oleaginosas aumentou a digestibilidade do extrato etéreo e reduziu a digestibilidade dos carboidratos totais. Não foram observadas diferenças para a concentração energética das rações. A inclusão dos grãos de linhaça, girassol ou canola nas rações de cabritos Saanen, em substituição (8% MS) ao milho, não traz benefícios ao desempenho, no entanto, esses alimentos podem ser utilizados sem que haja alteração do valor nutricional das rações.Termos para indexação: Digestibilidade, ingestão, suplementação lipídica, caprinos, desempenho.

“…The high lipid content of WCS may depress cell-wall degradation (Moore et al, 1986), due to some mechanisms as the physical coating of fibre by lipids, the shortage of cations due to formation of insoluble soaps, the inhibition of rumen microbial activity, and modification of the microbial population (Dayani et al, 2011).…”

“…In some studies concerning the effects of WCS as a replacement of cereals (Cunha et al, 2008;Dayani et al, 2011;Kandalys et al, 1998;Luginbuhl et al, 2000;Moore et al, 1994) on the performance and carcass traits of sheep and goats contradictory results have been reported. Moreover, there is a lack of results about the effects of the replacement of fibrous by-products (as soybean hulls) by WCS on performance and meat quality of lambs.…”

Byproduct as whole cottonseed (WCS) and soybean hulls are quite used in finishing diets to feedlot lambs and WCS is a potential source to be included in lambs diet when prices are advantageous. The most part of the studies with WCS is used as a replacement of cereals as corn. Thus, this study was conducted to evaluate the effect of replacing a fibrous byproduct (soybean hulls) with increasing levels of WCS (0, 10 and 20%) on the performance, carcass traits and meat quality of feedlot lambs. Thirty crossbred lambs (15 males and 15 females, 20±1.6 kg) were fed 1 of 3 high concentration diets: CTL (without WCS), WCS10 (with 10% WCS), and WCS20 (with 20% WCS) in a block design (sex) for 56 days. Feeding 10 or 20% WCS significantly (P=0.013) improved the feed conversion without affecting the final weight gain, average daily gain or dry matter intake in kg/d. However, the DMI (in %) of live weight was affected by treatments (P<0.0001): lambs fed the CTL and the WCS10 diet consumed more DMI than the lambs from WCS20 diet (4.19, 4.03 and 3.6%, respectively). The hot carcass weight, dressing percentage, longissimus muscle area and fat thickness were not affected by the WCS levels. The shear force and meat colour were similar among treatments. These results suggested that fattening lambs may benefit from an increase in feed efficiency from 10% WCS up to 20% without negatively impacting carcass and meat quality.

“…Luginbuhl et al (2000) reported that increasing WCS levels in diets of growing male goats increased serum urea nitrogen level quadratically. In contrast, Dayani et al(2011) reported that adding 20% of WCS in the diet did not significantly affect blood urea concentration, but decreased significantly when the CP level was reduced to 12%.…”

“…Warren et al (1988) reported that feed intake (FI) and digestibility were decreased when more than 30% WCS was included in a diet. Additionally, Dayani et al (2011) indicated that WCS in the diet of fattening lambs should be lower than 20%. Feeding WCS up to 20% of the diet decreased average daily gain (ADG) and feed conversion of fattening male lambs.…”

This study was carried out to determine the effect of whole cottonseed (WCS) supplementation on finishing performance and blood parameters of Awassi lambs under heat stress. The compositions of diets for the various treatments were i) control: concentrate without WCS plus 15% wheat straw; ii) 8.5% WCS, 76.5% concentrate and 15% wheat straw; and iii) 17% WCS, 68% concentrate plus 15% wheat straw. Twenty seven male Awassi lambs (4-5 months old) were allotted to three dietary treatments in equal numbers for each diet in a completely randomized design. Following 15 days of diet adaptation, lambs were fed the experimental diets ad libitum for 56 days. According to the finishing trial, average daily gain (ADG), feed intake (FI), dry matter intake (DMI), feed efficiency and water consumption were not affected by the inclusion of WCS. Only numerical increment of daily gain, FI and DMI was observed in the 8.5% WCS group. Supplementation of WCS did not affect blood glucose, urea, total protein, albumin and potassium levels, but blood cholesterol level was increased. Changes in scrotal circumference were observed with supplementation of 17% WCS. As a result, WCS can replace concentrate up to 8.5% of diet without negative effects on finishing performance of Awassi lambs under heat stress conditions.
