Abstract A cooperative study involving 189 litters from 114 sows [initial breeding body weight (BW), 200.8 ± 37.1 kg] was conducted at two experiment stations to investigate the effects of OmniGen AF (OG; Phibro Animal Health Corporation) supplementation in sow diets on reproductive performance and milk composition. Diets were: 1) corn-soybean meal-based control diet that met NRC (2012) requirement estimates or 2) control plus 0.75% OG. A common diet formulation was used by both stations. Sow allotment was balanced for breed, parity, and BW. Sows were allotted to diets at least 21 days prebreeding and were fed the diets continuously at 1.82 kg daily in gestation and ad libitum in lactation. Sow BWs were measured at breeding, prefarrowing, postfarrowing and weaning. Litter size responses were recorded within 24 h postpartum and individual pig weights were measured at birth and weaning. Milk samples were collected twice during lactation on d 5–7 and d 14–17. Supplementation with OG resulted in less (P < 0.05) BW change of sows during lactation (-12.1 vs. -8.2 kg). Total born (12.9 vs. 13.0), live born (11.7 vs. 12.0), and weaned (10.3 vs. 10.5) were similar for control and OG sows, respectively. Sows fed OG-based diets had greater (P < 0.05) litter weight for total born (18.3 vs. 19.3 kg) and weaned (63.2 vs. 67.0 kg), and lactation litter gain (47.8 vs. 50.7 kg). Lactation feed intake for control and OG sows (5.32 vs 5.52 kg, respectively) did not differ. Supplementing sow diets with OG increased (P = 0.057) lactose content (5.78 vs. 5.84%) and reduced (P = 0.047) protein content (4.77 vs. 4.68%) in milk. The results of this study demonstrated that supplemental OG at 0.75% in sow diets reduced weight loss during lactation and improved litter weights with marginal effects on milk composition of sows.

AbstractExperiment I. One hundred and twenty-five lactations from 88 New Zealand × Californian does were used to study the influence of high fat diets on the performance and milk yield of multiparous rabbit does in two high productivity situations: housed in hot conditions (minimum temperature above 24°C) with eight pups (group H8), or housed in warm conditions (minimum temperature under 21 °C) with 11 pups (group W11). Starting from a control diet (diet C) with 26 g ether extract (ЕЕ) per kg dry matter (DM), two isoenergetic diets were formulated adding fat from vegetable sources up to 99 g ЕЕ per kg DM (diet V) or animal sources up to 117 g ЕЕ per kg DM (diet A). The lactating does showed similar food daily intakes (⋍105 g DM per kg), therefore digestible energy intake of does on high fat diets was significantly higher (P < 0·001). The addition of f at to the diets increased (P < 0·001) milk yield of does (+21 and 24 g/day for diets V and A, respectively) and litter weight at weaning (P < 0·05), and decreased the number of pups replaced (P < 0·01) during lactation. Group H8 does had significantly lower DM intakes, litter growth rates and milk production levels than group Wll does (P < 0·001).Experiment 2. The effect of these diets on milk composition was determined in 62 lactations from 28 multiparous rabbit does, in which litter size was maintained at eight pups. Milk samples were collected manually on the 7th, 21st and 28th days of lactation. Milk of does given high fat diets, especially diet A, had higher fat and energy contents (P < 0·001) and a lower protein content (P < 0·001) than those given diet C. Milk of does given diet A had a greater DM content than those given the diets С or V (P < 0·001). There was a correlation between the fatty acid composition of milk and dietary fat. The proportion of odd chain fatty acids in the milk fat was lower for does given diet V (P < 0·05) than those given diet A. In conclusion, high fat diets were related to a higher milk yield and energy content of milk, allowing a higher litter weight gain and a lower mortality of sucking pups.

The growth rate of elephant seal pups during the suckling period is shown to be lower at Macquarie I. than at the Falkland Is. Dependencies. Earlier initiation of suckling and lower suckling frequency occurs in the more rapidly growing Falkland Is. seal pups. The analyses of the milk samples collected from Macquarie I. elephant seal cows at different stages of lactation are reported, and a striking difference in milk composition at the different stages is noted. An attempt to determine quantitatively the milk production of the elephant seal is described, and the inaccuracies of the methods used are discussed, with comments on how a better estimate could be obtained. It is concluded that the principal cause of depressed growth rate of elephant seal pups at Macquarie I. is disturbance within the harems. This disturbance has been alleviated to some extent at the Falkland Is. due to alteration in the structure of the population by long-term sealing operations. Indicative of disturbance within the harems at Macquarie I. were the high incidence of injury noted during dissection of 54 seal pups, the delayed initiation of sucking in new-born pups, and the higher frequency of sucking by pups.

Indigenous buffalo is the black gold of Nepal because of its important contribution to the livelihood of the rural farmers and agricultural economy of the country. A study was done to investigate the performance of indigenous buffalo found in high-hill of the western districts of Nepal. Further, effect of genetic and non-genetic factors on productive and reproductive performance of indigenous buffalo was accessed. This study was done in four districts: Myagdi, Baglung, Parbat and Kaski for 2 consecutive years from 2016 to 2017. A semi-structured and questionnaire survey format was prepared and was filled with verbal answers from 142 farmers on a different aspect of buffalo farming. Further, recording formats were distributed to enumerators for the recording of different information that cannot be collected from the survey. Total of 201 indigenous buffaloes (132 Lime and 69 Parkote) and minimum of 25 buffaloes in each site were measured for determining productive and reproductive performance. Further, 65 collected milk samples were subjected to Animal Nutrition Laboratory of DoAR, Lumle for determination of milk composition. Results of the findings revealed that there was a high variation in productive and reproductive performance of indigenous buffalo. Lactation milk yield of Lime buffalo was observed slightly higher (1180.90 ± 27.94 L) than Parkote buffalo (1170.56 ± 42.29 L) but was non-significant (p>0.05). Lactation yield of indigenous buffalo in Ramja, Parbat (1254.73±38.43 L) was observed significantly higher (P<0.002) than other research locations. Genetic evaluation of indigenous buffaloes and selection of better performers help in increasing productivity and lead to conservation by competitive advantage of indigenous buffaloes. Non-genetic factors play an important role in the productive and reproductive performance of indigenous buffalo and need to account for these effects to select buffalo for its genetic merit.

Lysophospholipids (LPL), a new feed additive, were supplemented to a pelleted total mixed ration (TMR) of dairy cows to examine its effects on feed intake, production, and composition of milk and plasma biochemical parameters. Two dietary treatments included diets supplemented without (control diet; CON) or with LPL at a dose of 0.5 g/kg of pelleted TMR. Twelve multiparous, mid-lactation, Holstein cows (Bodyweight 730 ± 9.3 kg; 100 ± 6.0 days in milk) were randomly assigned to one of the two dietary treatments with a 42-day measurement period after a 14-day adaptation period. Feed and water were provided ad libitum. Feed intake and milk yields were recorded daily, blood samples were collected fortnightly, and milk samples weekly. The results showed that the supplementation of LPL did not change feed dry matter intake, milk yields, and milk composition. However, it increased total protein and globulin and the activity of alkaline phosphatase and decreased total cholesterol in plasma. This study suggests that LPL may have beneficent effects in animal health but might be not a feasible feed additive to increase production for dairy cows fed a pelleted TMR.

This study was conducted to evaluate the effects of L-arginine supplementation levels during late gestation on reproductive performance and piglet uniformity in high prolific sows. A total of 60 F1 multiparous sows (Yorkshire × Landrace), with an average body weight of 238.2 kg, were allotted to one of three treatment groups in a completely randomized design. The dietary treatments were divided by the supplementation level of arginine during the late-gestation period, from day 70 to farrowing, as follows—(1) CON: corn-soybean meal-based basal diet (Arg 0.72%), (2) Arg10: basal diet + L-Arg 0.28% (Arg 1.0%), and (3) Arg15: basal diet + L-Arg 0.79% (Arg 1.5%). The same lactation diet was provided ad libitum to sows during the lactation period. There were no significant differences in body weight and backfat thickness in sows during late-gestation and lactation. Dietary arginine levels had no significant influences on the number of total born, stillbirth, and born alive. However, increasing inclusion level of L-arginine supplementation tended to increase (p < 0.10) alive litter weight linearly, and also linearly increased (p < 0.05) the piglet weight gain and litter weight gain during the lactation period. In piglet uniformity, the standard deviation of piglet birth weight (p < 0.05) and the coefficient of variation for piglet birth weight (p < 0.10) increased linearly, as dietary arginine levels increased in the late gestation period. Increasing L-arginine supplementation to late gestating sows linearly increased (p < 0.05) the blood concentrations of arginine and ornithine at day 90 and day 110 of gestation. On the other hand, dietary arginine levels in late gestation did not affect the blood parameters related to the nitrogen utilization. Increasing dietary arginine levels for the late gestating sows did not affect the milk composition for colostrum and milk at day 21 of lactation. In conclusion, the inclusion level of arginine in the diet for late gestating sows, by up to 1.5%, could improve the alive litter weight at birth and litter weight gain during lactation, whereas the piglet uniformity at birth was decreased due to the increase of survival for fetuses with light birth weight.

Abstract Sow feed intake during lactation is crucial to the maintenance of sow body condition, milk production, and litter performance. Loss of body weight or condition during this time could compromise future reproductive performance. Two groups (n = 52 total) of breeding age gilts and sows were used to evaluate whether a sensory additive would improve intake during the lactation period. Gilts/Sows were weighed, and back fat depth was measured, at 110 d of gestation prior to entering the lactation room, and again at weaning. The sows were sorted by parity and then allotted by BW at d 110 to Control or 0.075% sensory additive (Luctamax® SowVive, Lucta S.A., Barcelona, Spain). Experimental lactation diets were offered upon entry to the lactation room and fed through weaning. During this time feed was weighed back every three days. Gilts/sows were fed 2.72 kg/head/day until farrowing, and sows were placed on full feed 24 hours post-farrowing and allowed to eat ad libitum. Data was analyzed using the PROC MIXED of SAS as an RCBD with treatment as the fixed effect and group as a random effect. During lactation sows on the sensory additive diet showed an increase in intake during days 10 to 21 when compared to sows on the control diet (Table 1). Although it was not significantly different, sows fed sensory additive had numerically heavier weaning BW (239.4 vs 236.2 kg, P = 0.42) and increased litter weight gain (51.96 vs 48.69 kg, P = 0.24) compared to control fed sows. However, backfat thickness change during lactation did not differ between control and sensory additive fed sows (-4.74 vs -5.81 mm, P = 0.65). In conclusion, in the current study lactation diets supplemented with a sensory additive stimulated sow appetite during the lactation period.

AbstractNew Zealand × Californian rabbit does were offered ad libitum three diets: diet A, with 960 g lucerne per kg dry matter (DM), having 8•7 MJ digestible energy (DE) and 108 g digestible protein (DP) per kg DM; diet AF with 920 g lucerne and 50 g animal fat per kg DM, having 9•6 MJ DE and 105 g DP per kg DM; and diet C, as a control diet having 12•0 MJ DE and 122 g DP per kg DM. Productive parameters were measured for the first five parities, and food intake and milk yield during the first two parities.In experiment 1, 79 does (342 parities) were housed in a cooled building, litters were standardized to eight kits and weaned at 28 days of age. DM intake during lactation was lower (P < 0•001) but DE intake, milk yield and litter growth were higher for group C. Values for does on diet AF generally were between those of groups A and C. Average results for groups A, AF and C were respectively: 59, 65 and 51 days for the parturition interval; 160, 170 and 193 g for daily milk output in the first two lactations; 3•7, 4•0 and 4•5 kg for litter weight at weaning.In experiment 2, 64 does (294 parities) were housed in a climatic chamber at a constant temperature of 30oC, litters were standardized to six kits and weaned at 35 days of age. DM intake during lactation was lower (P < 0•001) but milk yield and litter growth were higher (P < 0•001) for C does. Average results for groups A, AF and C were respectively: 70, 70 and 56 days for parturition interval; 106, 128 and 128 g for daily milk output in the first two lactations; 3•7, 4•4 and 4•4 kg for litter weight at weaning. Lucerne-based diets allowed a reasonable performance of reproductive rabbit does in the long term, even under hot conditions.

Abstract The objective of this study was to determine the effects of increased AA and energy intake during late gestation on reproductive performance, milk composition, and metabolic and redox status of sows. A total of 118 Yorkshire sows (third through sixth parity) were randomly assigned to dietary treatments from day 90 of gestation until farrowing. Dietary treatments consisted of combinations of 2 standardized ileal digestible (SID) AA levels [14.7 or 20.6 g/d SID Lys, SID Lys and other AA met or exceeded the NRC (2012) recommendations] and 2 energy levels (28.24 or 33.78 MJ/d intake of NE) in a 2 × 2 factorial design. After parturition, all sows were fed a standard lactation diet. Blood samples were collected and analyzed for parameters on metabolism, redox status, and amino acid profile. The data were analyzed using the generalized linear mixed models to reveal the impact of dietary levels of energy, AA, and their interaction. Sows with increased intake of AA had greater BW gain (P < 0.01) during late gestation. Furthermore, the BW loss during lactation was increased in sows with increasing intake of energy (P < 0.05) or AA (P < 0.05). Sows fed high energy had higher total litter birth weights (20.2 kg vs. 18.4 kg, P < 0.05) and shorter duration of farrowing (261 min vs. 215 min, P < 0.05), compared with those fed low energy, which likely was due to higher (P < 0.05) plasma glucose and lower (P < 0.05) plasma lactate prior to parturition. High AA intake in late gestation increased the ADG of piglets during the following lactation (P < 0.05), and increased the concentrations of plasma urea, and the following AA: Lys, Met, Thr, Val, Ile, Leu, Phe, Asp, Ser, and Arg at farrowing (P < 0.05). In conclusion, the increased intake of energy increased total litter weight of newborns and shortened the farrowing duration, which likely was due to improved energy status at farrowing. Furthermore, sows with increased intake of AA led to higher growth rate of piglets during the following lactation, accompanying with the increasing levels of plasma urea and amino acids. Therefore, the higher energy intake in late gestation appeared to improve litter weight and farrowing duration, while higher AA intake may have positive effect on piglets performance in lactation.

The aim of this study was to determine the effect of supplementing different concentrations of extruded full-fat soybean (EFS) to corn-soybean meal-based lactation diets, at the expense of soybean meal and oil, on sow and litter performance. During gestation, a total of 60 Landrace × Yorkshire multiparous sows were fed the same gestational diet. After farrowing, sows were randomly allotted to one of four treatments including Control (corn-soybean meal-soybean oil), and 6.1%, 12.2%, and 18.3% EFS diets, until Day 21 of lactation. Individual weight at weaning tended to be heavier in the 12.2% EFS group as compared with Controls (P = 0.07). Litter weight in 12.2% EFS group was significantly increased compared with Controls, representing an increase of 7.8%. Average daily feed intake of sows in the 12.2% EFS group tended to increase (P = 0.08) when compared with the other three groups. At Day 21 of lactation, fat and protein content in the milk of the 12.2% EFS group were higher than those of the Control group (P &lt; 0.05). In conclusion, these results demonstrated that feeding lactating sows diets supplemented with EFS had a positive effect on milk composition as well as litter performance. Among the three dietary levels of EFS tested, 12.2% EFS supplementation level showed preferable reproductive performance.
