“…Moreover, the most of suckling milk in G2 and G3 groups may be due to increased volatile fatty acids (VFA's) concentration in rumen of goats given oil compared to G1 group. These results are in agreement with Kholif et al (2015) who explained that the anaerobic fermentation of oil (as linseed oil) was more efficient and faster in yielding more VFA's than control by indirect way. Enhancing milk amount with oil consumption in G2 and G3 attributed to high α-linolenic acid (ALA) in rations were able to upregulate the peroxisome proliferatoractivated receptors (PPAR-α) gene and downregulate the stearoyl-CoA-desaturase gene compared to control diets with low ALA content (Trabalza-Marinucci et al, 2016).…”

“…As a result, addition of oils to rations could improve milk harvest in dairy goats. This finding is confirmed with that of Kholif et al (2015) who recorded more average milk yield with goat received linseed oil (1256 g / d) than control goat free of oil (1140 g / d). Also, this study showed higher milk harvest with goat fed sunflower oil which was in the line of who found that sunflower oil could improved milk yield up to 1240 g /d compared to 1140 g / d for goat fed control diet.…”

Fifteen Zaraibi nanny goats were divided into three groups (N=5/group) and randomly assigned to three experimental diets: (1) control diet group free of oil (G1) fed concentrate fed mixture (CFM) + berseem hay (BH), (2) trial diet group (G2) received CFM+ BH+ linseed oil and (3) trial diet group (G3) fed CFM+BH+ sunflower oil (oil bottles are not suitable for marketing). All goats in G2 and G3 group received oils at the rate of 3% of dry matter intake. The study included evaluation of rations' consumption from flushing to mating, from trimester to parturition, during suckling and lactation months. Also, productive performance recovery included changing body weight of maternal, offspring number, litter size, average birth body weight of kids (at four days post-received colostrum), suckling milk amount, body weight of weaning kids, trading milk, blood metabolites and economic efficiency. The results indicated that oils addition in G2 and G3 reduced feedstuffs consumption from flushing up to parturition, during suckling and lactation months compared to goats in G1 group. Subsequently, the total consumption of rations for G1, G2 and G3 were 1200, 1191, and 1189 g / h /d from flushing to mating; 1390, 1380, and 1380 g / h /d during trimester to parturition; 1497, 1427 and 1427 g / h /d during suckling and 1223, 1210 and 1202 g / h /d during milking months, respectively. Consequently, the productive performance recovery such as changing body weight of maternal in G1, G2 and G3 groups from flushing (36.80, 36.78 and 36.44 kg) to parturition (37.48, 38.00 and 38.12 kg), offspring numbers was 8, 10 and 11 kids, litter size recorded 2.00, 2.50 and 2.20% and average body weight of birth kids reached to 2.90, 3.60 and 4.70 kg, respectively. Furthermore, the nanny goats in diet of G1 showed a lower (P < 0.05) suckling milk amount (1.79, 2.05, 1.92, 1.43 and 1.25kg /h) than nanny goats in G2 (2.75, 2.70, 2.65, 2.03 and 1.55 kg/h) and G3 (2.88, 3.05, 2.70, 2.20 and 1.58 kg/h) through evaluation period at 7, 15, 30, 60 and 90 days post-partum, respectively. In addition, body weight of kids at weaning recorded significant (P<0.05) differences among G1, G2 and G3, being 9.40, 11.10 and 11.90 kg, respectively. When, G2 and G3 groups received oils they could show the highest (P<0.05) yield of milk (363 and 389 kg) than goats in G1 (262 kg) during lactating months, respectively. But, no variation (P > 0.05) was observed in blood parameters among G1, G2 and G3, except glucose (62.35, 68.88 and 69.86 mg/dl) and calcium (9.01, 10.11 and 10.45 mg/dl). The economic efficiency indicated the best estimate in G3 (72.53%) followed by G2 (65.98%) and the less within G1 (55.55%). The results showed that the addition of linseed and sunflower oils to goats' rations could lead to a lower consumption of diet during critical periods (from flushing to parturition) of production. In addition, it has been found a better production performance recovery and economic efficiency than those fed feedstuffs alone.

“…The higher milk fat and lactose contents for treated goats could be related to the change in ruminal activity with experimental additives. Morsy et al (2012) and Kholif et al (2012Kholif et al ( , 2015 reported that rumen molar proportions of individual total volatile fatty acids and the acetate to propionate ratio were significantly (p<0.05) affected by plant oils additives. Increased milk lactose and fat contents with the SO addition may be due to the increased blood serum glucose concentration and increased rumen fermentation with SO goats (Ollier et al, 2009).…”

Oilseed lipids are important sources of unsaturated lipids. Among oilseeds, sunflower, linseed and soybeans seed are used both in farms and experimental work. Moreover, the improvement of unsaturated fatty acids and Conjugated Linoleic Acid (CLA) in milk products is important for human health. The aim of this work was to enhance the fatty acid profile of processed cheese by using milk from goats fed with different additives, namely sunflower seed or sunflower oil. Fifteen lactating goats, in early lactation, were distributed to three groups using complete randomized design for a three months experimental period. The treatments were: (1) control diet consisted of concentrate feed mixture: berseem clover (1:1 dry matter bases), (2) control +50 g/head/d sunflower seed and (3) control +20 mL/head/d sunflower oil. Milk of each treatment was pooled and used in processed cheese manufacturing by acidifying milk with diluted lactic acid until coagulation. Cheese samples were stored at 7°C for 3 months. Results showed that experimental additives increased (p<0.05) the total unsaturated fatty acids and CLA in the processed cheese. All additives decreased (p>0.05) the total saturated fatty acids and increased (p<0.05) the polyunsaturated fatty acids contents of the processed cheese fat. Processed cheese color, flavors and physical properties, such as oil separation melting index and penetrometer reading were not significantly affected (p>0.05) by the experimental additives. It may be concluded that sunflower seed or sunflower oil addition to lactating goat rations increased the nutritive value of processed cheese.

RESUMENLa utilización de enzimas fibrolíticas exógenas comerciales (celulasas y xilanasas) ha sido ampliamente empleada en producción animal, con la finalidad de complementar la actividad de las enzimas endógenas, para lograr un incremento en la respuesta de producción de leche. En esta investigación se pretende utilizar como alternativa el uso de enzimas exógenas obtenidas del sustrato gastado de Pleurotus ostreatus con el fin de evaluar los parámetros productivos de cabras. Los resultados mostraron que la inclusión en la dieta de este extracto enzimático, tuvo efecto sobre la ganancia diaria de peso, producción de leche y consumo de alimento. Lo que sugiere que el extracto enzimático obtenido del sustrato gastado de Pleurotus ostreatus, puede ser una alternativa para mejorar los parámetros productivos de las cabras. Palabras clave: leche, extracto enzimático, cabras. ABSTRACTThe use of commercial exogenous fibrolytic enzymes (cellulases and xylanases) has been widely used in animal production, in order to complement the activity of the endogenous enzymes, to achieve an increase in milk production response. In this research, we intend to utilize as an alternative the use of exogenous enzymes obtained from the spent substrate of Pleurotus ostreatus in order to evaluate the productive parameters of goats. The results showed that the inclusion in the diet of this enzymatic extract had an effect on daily weight gain, milk production, and consumption. This suggests that the enzymatic extract obtained from the spent substrate of Pleurotus ostreatus may be an alternative to improve the productive parameters of goats. Keywords: milk, extract enzymatic, goat. INTRODUCCIÓNPara obtener mejor producción en rumiantes es importante considerar el tipo de forraje que es consumido por estos, debido a que aunque cuentan con una gran variedad de enzimas fibrolíticas en el rumen (celulasas, xilanasas, ß-glucanasas, pectinasas), que se encargan de intervenir en el proceso de degradación del material alimenticio; la presencia de compuestos indigestibles como la lignina, demeritan el aprovechamiento de los forrajes y con ello la producción de estos animales (González, 2002), tal es el caso de las
