Impact of Feeding Some Forage Shrubs on Milk, Blood Parameters of Ewes and Growth Performance of Their Offsprings in Northern Coast.

Abstract

Forty mature Barki ewes at late pregnancy , 3-4 years old and 45.2±0.47 kg live body weight (LBW) divided into equal four groups were used in this work. This experiment aimed to evaluate the effect of feeding Acacia (AC) Acacia saligna , Atriplex (AT) Atriplex halimus, Cassava (CA) Manihot esculenta. compared to berseem (Trifolium Alexandrinum) hay (BH) on yield, chemical composition and rheological properties of milk, hematological and biochemical blood parameters of ewes, and growth performance of their offspring's. Ewes were fed control diet in G1 consisted of : concentrate feed mixture, rice straw plus BH at levels of 60:10:30%, respectively. Only BH in (G1) was replaced by AC in (G2), or AT in (G3) or CA in (G4) stems and leaves planted in the salt soil. All animals were kept under the same managerial conditions. Results showed insignificant effect of dietary treatment on LBW of ewes. Ewes fed AT in (G3) showed higher (P<0.05) milk yields than in control group (G2), while ewes fed CA (G4) showed the highest (P<0.05) milk yields, ewes fed AT (G3) did not differ than those in control group (G1). Milk fat, lactose and ash contents in milk were not affected by dietary treatment during all lactation weeks. Protein content was higher (P<0.05) in G2 and G3 than in G1 and G4 at all lactation weeks. Total solids (TS) content was lower (P<0.05) in G4 than in other groups during the 1 st six weeks of lactation, being the highest (P>0.05) in G1 at the 7 th lactation week. Atriplex treatment was accompanied by high level of ca and p .Calcium and phosphorus content were affected significantly (P<0.05) by dietary treatment, being significantly (P<0.05) higher in milk of ewes of G3 than in G1, G2 and G4 at all lactation weeks. The differences were significantly (P<0.05) between G2 and (G1 and G4) at all lactation weeks, although no significant different of Calcium content between G1 and G4 except in 6 th an 7 th week, however, no significant differences of phosphorus content between G2 and G4 although there were no significant differences between them and G1 at all lactation weeks. Slight differences were detected in acidity, pH value, density and freezing point of milk, ranging from 0.16 to-0.20%, 6.62-6.81, 30.47-36.27% and from-0.49 to-0.64%, respectively. Rennet coagulation time (RCT) values were the lowest through 6 lactation weeks in G2 (98-125 s), and the highest in G4 (143-154 s). Curd tension (CT) was the highest in G2, and the lowest in G4 at 2 and 7 lactation weeks. Trend of Whey Syneresis values of all treatments was opposite to that of Curd Tension. The highest values was recorded with Cassava. Red blood cells (RBCs) count did not differ in G2, G3 and G4 than that of G1. White blood cells WBC's count, Ht,% and Hg, g/dl concentration were higher (P<0.05) in G4 than in G2 and G3. Concentration of total protein (TP), urea-N, Ca and Ca/P ratio increased (P<0.05) in G2 compared with G4, while both groups did not differ from those in G1 and G3. Concentration of creatinine, triglyceride (TG) and Total cholesterol (TCh...

Studies on Mixing Tanniniferous Plants With Ammoniated Wheat Straw in Barki Sheep Rations on Digestibility, Performance and Some Blood Biochemical

“…Fig ( ), it's worth noting that total gain and average daily gain of lambs (males and females) was not affected at different ages affected by their mothers feeding shrubs plants. These results agreement with Shetaewi et al (2001), Fasae et al(2015) and El-Saadany et al (2016). This means that feeding ewes during pre-and postpartum period on different forage types in this study was save without adversely effects on growth performance of lambs produced.…”

“…In agreement with the present results, Abdalla et al, (2013) found that fat percentage in goat milk was not affected by type of roughages. Also, El-Saadany et al, (2016) cleared that there was a non-significant tendency of decrease in fat content in ewes milk fed Cassava as compared to other groups during all lactation weeks.…”

Effect of Using Tanniniferous Plants Shrubs in Feeding Barki Ewes on some Productive and Physiological Parameters

“…The concurrent results come in agreement with those obtained by Shetaewi et al (2001); Fasae et al (2015) and EL-Saadany et al (2016) who recorded differences (P<0.05) between ewes fed Acacia, Atriplex and Cassava when compared with those fed Berseem hay in total gain and average daily gain of lambs. On the other hand, these results are not in accordance with those obtained by Mohammady et al (2014) who reported higher weaning weight and daily gain (P<0.05) in Barki lambs fed BH when compared with those fed tanniniferous plants shrubs.…”

“…Plasma globulin while increased in ewes fed BH it decreased in those fed tanniniferous plants. EL-Saadany et al (2016) found significant increase in total plasma protein concentration between experimental groups (Acacia, Atriplex and Cassava vs. Hay). With regard to albumin, Shaker et al (2008) recorded that plasma albumin was higher in Barki lambs fed mixture of Acacia and Atriplex.…”

“…Tanniniferous plants shrubs are distinguished with minimum use of brackish or saline irrigating water and tolerable to arid or semi-arid conditions. They also give good biomass yield which could be used for feeding sheep and goat (EL-Saadany et al, 2016).…”
