“…During the prepartum period, the treatments had no effect (P>0.05) on DMI and BW (Table 2), which corroborates results of Zambom, Alcalde and Macedo (2006), who evaluated dietary energy levels in Saanen goats during prepartum, and results of Sahlu, Hart and Le-Trong (1995) in Alpine goats.…”

Efeitos de níveis de energia na dieta utilizando sais de cálcio de ácidos graxos sobre o valor nutritivo das dietas e qualidade do leite em cabras leiteiras no periparto ABSTRACTPeripartum is a critical period for dairy goats, as dry matter intake (DMI) is not enough to supply the energy requirement for foetal growth and subsequent lactation. The objective of this study was to evaluate the use of calcium salts of fatty acids (CSFA) to increase dietary energy level of peripartum dairy goats and its effects on nutritive value of diets and milk quality. Twenty multiparous Saanen goats (body weight 63.5±10.3 kg) were distributed in a completely randomised design in four treatments at the following dietary energy levels: 2.6 Mcal of metabolisable energy per kg of dry matter (Mcal ME/kg DM) -control diet; and 2.7, 2.8, and 2.9 Mcal/kg DM -with added CSFA. Goats were housed in individual stalls and evaluated in the peripartum period, by measuring body weight (BW), DMI, dry matter and nutrient digestibility of diets, blood composition, and milk quality and yield. Increasing dietary energy level to 2.9 Mcal ME/kg DM had no effect on BW and did not limit DMI. CSFA supplementation increased intake of total digestible nutrients and did not affect fibre digestion. Blood triglycerides and cholesterol concentration increased with CSFA addition. The treatments had no effect on milk yield and composition; however, CSFA supplementation changed the fatty acid concentration of milk fat, increasing levels of polyunsaturated and essential fatty acids. In conclusion, peripartum dairy goats supplemented with CSFA to increase dietary energy level up to 2.9 Mcal ME/kg DM had a greater supply of total digestible nutrients and showed altered fatty acid concentration of milk fat.Index terms: Digestibility, calcium soap, fatty acid, Lactoplus ® , protected fat. RESUMOO periparto é um período crítico para cabras leiteiras, onde a ingestão de matéria seca (IMS) não é suficiente para suprir os requerimentos energéticos para o crescimento fetal e lactação subsequente. Neste estudo, objetivou-se avaliar o uso de sais de cálcio de ácidos graxos (SCAG), para aumentar o nível de energia na dieta de cabras leiteiras no periparto e seus efeitos sobre o valor nutritivo das dietas e qualidade do leite. Vinte cabras multíparas (63,5±10,3 kg) foram distribuídas em delineamento inteiramente casualizado, em quatro tratamentos com os seguintes níveis de energia na dieta: 2,6 Mcal de energia metabolizável por kg de matéria seca (EM/kg de MS) -dieta controle; 2,7; 2,8; e 2,9 Mcal de EM/kg de MS -com adição de gordura protegida. As cabras foram confinadas em baias individuais e avaliadas durante o período do periparto, acompanhando o peso corporal (PC), IMS, digestibilidade da matéria seca e dos nutrientes da dieta, concentração bioquímica sanguínea, produção e qualidade do leite. O aumento no nível de energia da dieta até 2,9 Mcal de EM/kg de MS não teve efeito sobre PC e não limitou a IMS. A suplementação com SCAG aumentou a ingestão de nutrientes digestíveis...

“…This amount of Ca ++ in colostrum corresponds to nine times the total serum amount in a 600-kg cow. Similarly, Zambom et al (2006) and Mundim et al (2007) found an increased demand for Ca ++ and other nutrients in dairy goats at the beginning as well as the peak of lactation, occurring on average between 40 and 60 days after partum, a finding that was also observed in our research.…”

In order to differentiate groups of hypocalcemic (G1) and normocalcemic animals (G2) and infer the influence of subclinical hypocalcemia on metabolic profiles, this study determined calcium concentrations during the transitional period in 35 dairy goats healthy, pregnant, primiparous or multiparous, crossbreed or pure-bred dairy goats producing average 3 kg/day/goat. Therefore, blood samples were collected before (30, 20 and 10 days before parturition), on the day of delivery and after parturition (10, 20, 30, 40, 50 and 60 days postpartum). The variables measured were glucose, nonesterified fatty acids, β-hydroxybutyrate, cholesterol, triglycerides, amylase, total protein, albumin, urea, creatinine, aspartate aminotransferase, gamma glutamyl transferase, creatine kinase, total calcium, phosphorus, magnesium, chlorides, cortisol and insulin, as well as ionized calcium (Ca++), sodium and potassium. Goats were considered to have subclinical hypocalcemia if Ca++ ≤0.72 mmol/L. The data were analyzed by ANOVA. In subclinically hypocalcemic goats, serum concentrations of Ca++ decreased earlier (10dbp) than in normocalcemic goats (parturition) and remained lower throughout the transitional period (p=0,004). Among the measured variables, Ca++ showed greater influence on the NEFA, glucose, insulin and total calcium but also influenced the protein profile. Lower food intake by goats with subclinical hypocalcemia was one of the main factors interfering with the metabolic profile and likely the productivity of these animals. Studies should be conducted to measure the effects of subclinical disease on the production rates and on the emergence of other transitional period diseases.

“…However, there was less dry matter intake due to compression by fetus and level of 1.5% supplementation promoted better weight maintenance during period of higher nutritional requirement. Zambom et al (2006) reported that, fundamental for increased intake of energy and protein avoiding mobilization of body tissues and to minimize the consequences of negative energy balance. Table 2 shows that the body condition score were decrease near parturition with regardless of breed and level of supplementation.…”

The present study was to evaluate the effect of level of concentrate supplementation on the intake and some indicators of the metabolic parameters of native ewes in pregnancy and supplemented in a grazing system. 28 lactating ewes were selected: 14 Morada Nova (MN) and 14 Santa Inês (SI) were distributed in an experimental design completely randomized in 2x2x3 factorial arrangement with two breeds (MN and SI), two levels of supplementation (0.5 and 1.5% body weight) and three experimental periods (75, 105 and 135 days of pregnancy). The concentrate intake and total dry matter intake (DMI) was higher (P <0.05) on SI ewes and, in animals supplemented with 1.5% of concentrate, where the pregnancy progresses promoted the progressive decrease of DMI. There was breed effect (P <0.05) on metabolic parameters evaluated, in which the two breeds presented the same trend of mobilization of body reserves with decrease (P <0.05) in the body condition score close of parturition. Supplementation did not influence in the metabolic parameters. The metabolic parameters were influenced by breed, however, with normal values, indicating a good adaptability of the MN and SI breeds at the experimental conditions, promoting an evolution of production rates with 0.5% of concentrate supplementation.
