The Impact

Abstract Three experiments were carried out to study whether a gestation diet, a simple transition diet, or a lactation diet is the best choice in late gestation and when sows preferably should be transferred to a high crude protein (CP) lactation diet. In experiment 1, 35 sows were fed either a gestation diet (12.1% CP), a lactation diet (15.9% CP), or a 50/50 mix (simple transition diet; 14.0% CP) from 6 d before parturition until parturition, to study the impact on farrowing and colostrum performance. In experiment 2, 90 sows were studied from 6 d before parturition until weaning at day 24 and they were fed one of five strategies: a gestation diet until day 3 or day 10 of lactation (strategy 1 and 2) and then lactation diet; a simple transition diet until day 3 or day 10 (strategy 3 and 4) and then lactation diet; or a lactation diet throughout the study (strategy 5). In experiment 3, 124 sows were fed strategy 1 or 5. Sows were weighed and back fat (BF) scanned when entering the farrowing unit and at day 2, 10, 17, and 24. Piglets were weighed at birth and after 24 h, and colostrum production was studied (experiment 1). Litter weight at day 2, 10, 17, and 24 was recorded, milk and blood samples were collected weekly and sow fat and protein mobilization, and balances of energy, N, and Lys were calculated from day 3 to 10 of lactation (experiment 2). Total- and live born piglets, and frequencies of stillbirth and piglet diarrhea were recorded (experiment 3). Feeding sows a gestation diet, a simple transition diet, or a lactation diet showed no evidence of effects on colostrum production or farrowing process (experiments 1 and 3) or lactation performance (experiments 2 and 3). Compared to previous studies, sows had a poor milk yield. Plasma urea was elevated (P < 0.001) indicating CP oversupply prior to parturition in sows fed the lactation diet as compared with the two other diets. According to calculated balances, all dietary strategies supplied insufficient amounts of N and Lys from day 3 to 10, indicating that the best choice is to feed sows with a high CP lactation diet from parturition and onwards. Primiparous sows had a higher plasma insulin concentration (P < 0.01), lower colostrum yield (P < 0.01), and higher frequency of piglet diarrhea (P < 0.001) than multiparous sows. In conclusion, in our conditions (high CP in gestation diet; poor milk yield; restricted feeding in early lactation), sow performance was not compromised by the dietary strategies, but results indicate that primiparous and multiparous sows should be fed differently.

The Impact

Abstract The impact of diet deprivation followed by overallowance during gestation on metabolic status of pregnant gilts and their lactation performance was determined. Gilts were fed a standard diet until day 27 of gestation and were subsequently reared under a control (CTL; n = 28) or an experimental (treatment, TRT; n = 26) dietary regimen. The experimental regimen provided 70% (restriction diet, RES) and 115% (overallowance diet, OVER) of the protein and NE contents provided by the CTL diet. The RES diet was given from days 28 to 74 of gestation followed by the OVER diet from day 75 until farrowing. Blood samples were obtained from all gilts on days 28, 75, and 110 of gestation, and on days 3 and 20 of lactation to measure concentrations of IGF-1, urea, FFA, and glucose. Milk samples were collected from 12 sows per treatment on day 19 of lactation and sow feed intake was recorded daily throughout lactation. Piglets were weighed at 24 h (after standardization of litter size), and on days 7, 14, and 21 (weaning). The TRT gilts gained less BW than CTL gilts (17.3 vs. 31.7 kg; P < 0.01) from days 28 to 75 of gestation and more BW (29.5 vs. 21.9 kg; P < 0.01) from days 75 to 110, but their overall gain from mating to day 110 was lower (61.4 vs. 67.2 kg; P < 0.05). Metabolic status during gestation was affected, with TRT gilts having less IGF-1 and urea, and more FFA than CTL gilts on day 75 (P < 0.01), and more urea on day 110 (P < 0.01). Growth rate of suckling piglets, sow lactation feed intake, and standard milk composition in late lactation (DM, fat, protein, lactose) were not affected by treatment (P > 0.10). In conclusion, diet deprivation of gilts as of day 28 of gestation followed by overfeeding from day 75 of gestation until farrowing did not improve lactation performance. It is likely that the compensatory growth that took place in late gestation was not adequate to illicit beneficial effects.

The Impact

This study was to investigate the impact of concentrate supplementation on the growth, milk yield and quality, postpartum heat period and days open in transient buffalo. Hence, six selected indigenous transient buffaloes were equally divided into two groups viz. control (n=3) and supplemented (n=3). About 56.0 kg mixed green fodders (Para:German=3:1) and 2.0 kg concentrate mixtures were offered as a basal diet to each buffalo. Besides these, an additional amount (0.5 kg) of concentrate mixture (wheat bran-50%, mustard oil cake-40%, common salt-2% and di-calcium phosphate-8%) was supplied to each buffalo of the supplemented group. The dry matter intake of the supplemented buffalo was 2.5 and 2% higher (p<0.001) at pre- and post-partum period, respectively than that of the control fed buffalo. Pre- and post-partum body weight, and body condition score of buffaloes between the group were found similar (p>0.05). About 20% more (p=0.02) milk was obtained in the supplemented group compared to the control group, however, the milk composition was not different (p>0.05). Calf birth weight was found ≈10% higher (p=0.51) in the supplemented group than that of the control group. Postpartum heat period and days open of the supplemented buffaloes were reduced remarkably by 13 and 14 days, respectively compared to the buffaloes in control group. Overall, concentrate supplementation to the transient indigenous buffaloes has noteworthy effects on milk yield, postpartum heat period and days open. Bang. J. Anim. Sci. 2020. 49 (1): 83-90

Boswellia Sacra

As an attempt to prevent transition-period-associated metabolic disorders and/or diseases, the potential benefits of Boswellia sacra (Bs) resin on hematology, immunity, metabolic status, udder and uterus health biomarkers, and milk production were examined in transitioning goats. From 2 weeks prepartum to 7 weeks postpartum, goats (n = 7/treatment) orally received 0 (control, nBS), 2 (BsL), or 4 (BsH) g of Bs resin/goat/day. The results showed that both Bs treatments significantly improved the activity of phagocytes. Both Bs treatments significantly decreased the concentrations of blood plasma urea, non-esterified fatty acids, hydroxybutyric acid, and interleukin-1β, whereas they increased the total antioxidant capacity compared with the nBS treatment. Both Bs treatments significantly decreased the uterine horn diameter and tended to decrease the intrauterine fluid content, indicating improved uterine involution compared with no treatment. Compared with the nBS treatment, both Bs treatments significantly decreased the milk somatic cell count. The lowest milk interleukin-1β content was observed in goats that received the BsL treatment, followed by those that received the BsH and nBS treatments. The BsL treatment significantly increased the concentration of immunoglobulin M (IgM) in the colostrum compared with the other treatments. Both Bs treatments significantly increased the daily milk yield compared with the nBS treatment but did not affect milk composition or the fat-to-protein ratio. In conclusion, supplementing lactating goats in the transition period with Bs resin at a dose of 2 g/goat/day positively affected the body lipid metabolism, udder and uterus health, colostrum IgM content, and milk yield due to its antioxidant and anti-inflammatory effects.

Abstract. Title of the paper: The impact of nutrition and non nutrition factors on milk urea concentration. I. The impact of nutrition factors on milk urea concentration The object of this study was to determine the impact of dietary crude protein / energy balance, stage of lactation parity, milk yield or milk protein yield, milk protein content, somatic cell count, season and herd on milk ureä concentration under the conditions of large herds (50–1000 dairy cows) and routine milk yield recording. From this data a model was created to predict the milk urea concentration for a single dairy cow or a feeding group For the analysis of the data a mixed linear model (proc mixed; SAS®, 1997) was used. The fixed effects (ratio of crude protein / energy, degradability of dietary crude protein, ruminal N-balance, lactation period, parity) was computed by generalized least-squares-means. The season, herd and month were used as random effects Milk yield or milk protein yield, milk protein content, somatic cell count and day in milk were included as Covariables in the model. The effect of dietary crude protein / energy balance on milk urea was significant (p < 0.0001). For diets with an optimal ratio of crude protein / energy (according to GfE, 1997) 226 mg/1 was calculated using least-squares-means. For diets with excess of crude protein this figure rose to 252 mg/1 In this study a significant difference in least-squares-means calculated urea concentration did not existed for degradability of dietary crude protein. On the other hand, a significant difference in least-squares-means calculated urea concentration existed for ruminal N-balance between 0 and 2.

The Impact

This is an experiment aimed to study the effect of re-mating interval on rabbit does after first kindling on hormonal (insulin, leptin, and T3) and metabolites (triglycerides, urea, and glucose) levels. DNA damage in ovary cells of rabbit does during the 2nd parity was also studied. Two varieties were used: APRI (synthetic line) and Baladi Black (BB, Egyptian breed). A total number of 120 mature rabbit does (60 does for each breed) were 6 months of age and were used at the beginning of the breeding season. Does of each breed were divided into three equal groups according to reproductive rhythm. The 1st group was postpartum (PP). The 2nd group was 11 days after parturition (P11). The 3rd group was post-weaning (PW). There were significant (P&ge;0.05) differences in plasma leptin concentration during 1st parity. The highest value of plasma leptin concentration was recorded by the PW group at mating. Also, there were significant differences in plasma insulin and T3 hormones concentrations of doe rabbits. The highest value of plasma insulin concentration was recorded by the PW group at mating in 1st parity and the highest value of plasma T3 hormone concentration was recorded for the PS group at mating. While there were insignificant differences during 2nd parity in T3 hormone concentration in rabbits, the differences of plasma glucose and triglyceride concentrations of doe rabbits during 1st parity and 2nd parity were significant. However, the highest significant value of plasma glucose concentration was recorded by the PW group at mating. On the other hand, there were insignificant differences in plasma urea concentration of doe rabbits during 1st parity and 2nd parity. Finally, no significant effects were observed on comet length, head diameter, tail length, or DNA % tail.

Lactating Dairy Cattle

The transition period of the dairy cow is physiologically and nutritionally stressful, particularly as feed intake is reduced and nutrient demands for foetal growth and initiation of milk synthesis are increased. It has been suggested that feeding concentrates in late gestation promotes the development of ruminal papillae, which takes 4 to 6 weeks to fully develop, consequently resulting in improved absorption of volatile fatty acids and increased food intake during early lactation. A recent study undertaken at this Institute (Keady et al. 1999) concluded that relative to silage offered ad libitum as the sole diet supplementation with 5 kg of concentrate during the last 28 days of gestation increased milk fat by 1.5 g/kg and improved milk yield by 0.6 kg/day during the first 12 weeks of the subsequent lactation. The response to dry cow supplementation reported by Keady et al. (1999) could have been mediated either by increased nutrient intake or by changes in the forage to concentrate ratio of the diet during the dry period. The present study was undertaken to evaluate the effect of level of energy intake and source of nutrients in late gestation on subsequent milk yield and composition.

Lactating Dairy Cattle

The transition period (last four weeks of pregnancy and the first four weeks of lactation) is the most traumatic period in the annual cycle of the dairy cow. It is physiologically and nutritionally stressful, particularly as food intake is reduced, especially in the last few days prior to calving, whilst nutrient demands for foetal growth and initiation of milk synthesis are increased. As the genetic merit of the national herd has increased considerably in the last ten years, improved nutritional management of cows during the transition period may be more important in reducing or preventing the cumulative loss of body condition, particularly in early lactation. The present study was undertaken to evaluate the effect of level of concentrate intake in late gestation on subsequent milk yield and composition.

SUMMARYA grazing experiment was conducted for 8 weeks in the spring/summer of 1993 at Palmerston North, New Zealand, to study the effects of condensed tannins (CT) inLotus corniculatus(birdsfoot trefoil cv. Grasslands Goldie) upon the lactation performance of ewes rearing twin lambs. Effects of CT were evaluated by studying the responses of ewes to twice daily oral supplementation with polyethylene glycol (PEG; MW 3500), which binds and inactivates CT. A rotational grazing system with restricted feed allowance was used. Measurements were made of pre- and post-grazing herbage mass, the composition of the feed on offer and diet selected, voluntary feed intake (VF1), milk yield and composition, liveweight gain and wool production. The concentration of metabolites in rumen fluid and in blood plasma was also measured. Lotus contained 35–5 g total nitrogen and 44–5 g total CT/kg dry matter in the diet selected, with anin vitrodigestibility of 73%. At peak lactation (weeks 3 and 4) milk yield and composition were similar for control (CT-acting) and PEG-supplemented (CTinactivated) ewes but, as lactation progressed, the decline in milk production and in the secretion rates of protein and lactose were less for control than for PEG-supplemented ewes. In mid and late lactation (weeks 6–11), control ewes secreted more milk (21 %), more milk protein (14%) and more lactose (12%) than PEG-supplemented ewes. Milk fat percentage was lower for control than for PEG-supplemented ewes, but secretion rates of fat were similar for the two groups. VFI, liveweight gain and wool growth were similar for both groups. Plasma urea and glucose concentrations were lower for control than for PEG-supplemented ewes, but concentrations of non-esterified fatty acids (NEFA), growth hormone and insulin were similar for the two groups. The concentrations of ammonia and molar proportions ofiso-butyric,iso-andn-valeric acids in rumen fluid were lower for control than for PEG-supplemented ewes; molar proportions of acetic, propionic and H-butyric acids were similar for the two groups. It was concluded that for ewes rearing twin lambs grazingL. corniculatus, the action of CT increased milk yield and the secretion rates of protein and lactose without affecting VFI, thereby increasing the efficiency of milk production. The increased milk production did not appear to be mediated by effects on plasma concentrations of growth hormone or insulin.

The Impact

Maternal diet during early gestation affects offspring phenotype, but it is unclear whether maternal diet during late gestation influences piglet metabolism. We evaluated the impact of two dietary protein levels in sow late gestation diet and piglet nursery diet on piglet metabolism. Diets met or exceeded the crude protein and amino acid requirements. Sows received either 12% (Lower, L) or 17% (Higher, H) crude protein (CP) during the last five weeks of gestation, and piglets received 16.5% (L) or 21% (H) CP from weaning at age 3.5 weeks. This resulted in a 2 × 2 factorial design with four sow/piglet diet treatment groups: HH and LL (match), HL and LH (mismatch). Piglet hepatic tissues were sampled and differentially expressed genes (DEGs) were determined by RNA sequencing. At age 4.5 weeks, 25 genes were downregulated and 22 genes were upregulated in the mismatch compared to match groups. Several genes involved in catabolic pathways were upregulated in the mismatch compared to match groups, as were genes involved in lipid metabolism and inflammation. The results show a distinct interaction effect between maternal and nursery diets, implying that sow late gestation diet could be used to optimize piglet metabolism.
